How to assemble ventilation for a swimming pool. Organizing pool ventilation: the best methods for organizing air exchange. Pool ventilation design rules

Water constantly evaporates from the vast area of ​​​​the pool's water surface, droplets settle on the ceiling, windows and walls. In such a humid and warm environment, pathogens of mold and fungi thrive. The same cannot be said about the pool visitors. Significant damage is also caused to structural elements. Condensation not only looks unattractive, it gradually destroys finishing materials.

Increased indoor air humidity leads to the following consequences:

• metal structures become covered with rust;
• fungus develops;
• plastered surfaces swell and collapse;
• painted parts become dull and become stained;
• conductivity increases insulating materials, there is a possibility of electric shock.

That's why in swimming pools ventilation units required. If we are talking about water parks or indoor sports pools, additional air dehumidification is usually required.

Air humidity is one of the most important indicators that determine the quality of ventilation. Humidity is the amount of water vapor per unit volume of air. At high humidity people are having trouble breathing. But too dry air in the pool is also a minus. As the water evaporates intensely, it cools swimmers' bodies, causing discomfort.

When designing pool ventilation, the mode of its operation, the climatic conditions of the area and the wishes of the customer are taken into account. The peculiarity of swimming pool ventilation is that design parameters water and air temperature have a significant impact.

Microclimate of the pool room

The maximum amount of water that air can accept at a certain temperature is called saturation humidity. An increase in air temperature entails an increase in the level of this indicator. The level of moisture in the air is determined by the mass in grams divided by 1 kg of air. If the saturation humidity threshold is passed, the excess settles on the walls, glass, and ceiling.

Before ventilation in the pool, moisture evaporation should be reduced by achieving a certain combination of water and air temperatures.

The air temperature is 1 - 2 degrees higher than the water temperature.

A minimal amount of moisture evaporates, which means that less powerful equipment for pool ventilation is needed. At equal air and water temperatures, the saturation point is reached with air humidity of 100%.

But in order for people in the pool to feel comfortable, the humidity should be from 50 to 65%. This indicator can only be achieved through a mechanical ventilation unit for the pool.

Evaporation is somewhat reduced if you cover the surface of the water with special blinds. The covered water hardly evaporates and does not cool due to evaporation.

For comparison:

• 2.3 liters evaporate from an open mirror of water in an hour;
• from closed - 1.2 liters per hour.

That is, resource savings are ensured when operating the pool.

Ways to reduce humidity in a swimming pool

It is impossible to completely prevent the evaporation of moisture in the pool. But it is quite possible to reduce it by installing a dehumidifier, supply and exhaust ventilation, or a combination of both methods.

Reducing air humidity can be done in two ways:

• condensation;
• assimilation.

Moisture condensation in the pool

The air is forced through a dehumidifier where its temperature reaches its dew point. The moisture condenses, after which the air is heated to the desired temperature and returned to the room.

Such installations are good for ventilating a swimming pool in a cottage, where it is impossible to implement an influx-exhaust system. The design is equipped with a hygrostat, which starts the compressor when the humidity reaches a certain reading. As soon as the humidity drops, the hygrostat stops the compressor. The fan can continue to rotate.

Condensation type dryers are:

• Wall-mounted, which are hung on the walls. They can be installed in a room with finished finishing;

• Wall hidden. All equipment is hidden in the adjacent room; only the fence grille opens into the pool room. It is necessary to plan such a pool ventilation system in a private house at the construction stage;

• Stationary. This powerful installations requiring special premises. They can be included in the supply and exhaust ventilation system for the pool sports complex. A stationary dehumidifier allows the addition of 1/5 of the air volume. Air supply and exhaust are provided by a system of air channels. Having equipped the system duct heater, we get full ventilation.

Assimilation of moisture in the pool

Supply and exhaust systems operate on this principle, using the ability of air to absorb water vapor. Rough calculations assume a 5-fold air exchange per hour.

Often in temperate latitudes To maintain the necessary microclimate in a small private pool, only ventilation is sufficient. But when calculating the ventilation of swimming pools of sports or entertainment complexes, you cannot do without a dehumidifier. Especially if they are located in places with a hot climate.

The assimilation method is good because the air is cleared of unpleasant odors. Its most significant drawback is its dependence on the weather. If the humidity of the atmospheric air is high, then it will not absorb moisture when it enters the pool room. However, in many cases this is the scheme that is used in practice.

The second significant drawback is that the supply air must be heated. This is especially noticeable in the cold season, when maximum energy is spent on heating.

Combined pool drainage method

The optimal type of dehumidification and ventilation installation for intensively visited swimming pools and large area. Experts recommend using both a dehumidifier and forced ventilation. The systems can be independent, not connected in any way, or form a common microclimate maintenance system.

This is expensive equipment that justifies itself only in pools with an area of ​​at least 50 square meters. meters.

Ways to maintain air temperature and remove odors in a pool

The air temperature in the pool room must be maintained above atmospheric. For this purpose, a heating system is installed. The air coming from the supply ducts is heated to a temperature maintained by the heating system. However, ventilation equipment is not designed to heat a room.

Air heating in in this case does not justify itself, since intense air movement accelerates the evaporation of water. It can only be used as an additional heating system if the main heating system cannot cope.

If the room is heavily glazed, the pool is located in the southern region, and additional air conditioning is provided.

In heavily trafficked large swimming pools natural ventilation is powerless, so forced methods of air movement are used. They provide stable temperature, supply fresh air, elimination of unpleasant odors and comfort for visitors.

Most effective method provision best conditions in the pool - this is the installation of supply and exhaust ventilation.

Advantages of the supply and exhaust system:

• a supply of fresh air is ensured;
• Excess moisture is removed from the atmosphere of the pool room.

The system is equipped with an air dehumidifier, and excess heat is removed to the street. It is autonomous and is not connected to the air exchange of the rest of the building. Ventilation ducts are made from materials that are resistant to moisture. The equipment is controlled automatically, supporting constant temperature and a mixture of clean air.

Before being supplied to the room, air from the street is filtered, cooled or heated, and its humidity also changes depending on the specified parameters.

Microclimate parameters for swimming pool:

• water temperature +26 – 31 degrees;
• air temperature +27 – 32 degrees;
• humidity from 50 to 65%;
• air exchange per visitor is 80 cubic meters per hour;
• air movement speed up to 0.2 meters per second;
• the concentration of chlorine molecules is up to 0.1 milligrams per cubic meter of air.

Water temperature in pools and saunas:

• hot +35 degrees;
• cold +15 degrees.

Possibility of heat recovery in the pool

A pool ventilation system in a cottage or water park with heat recovery will save significant money on heating the supplied air. The recuperator uses heat from exhaust air to heat fresh air. The heat exchanger can have a plate design, a rotary one, or operate on the principle of a heat pump.

Recuperation in the summer allows you to cool the air supplied inside. On average, savings per year are about 70%. The installation is equipped with filters and a heater, which, if necessary, brings the air temperature to the required temperature (for example, in winter).

Pool ventilation design rules

Swimming pool ventilation design is enough difficult process, taking into account many nuances. Only a specialist can competently plan pool ventilation with your own hands.

When calculating pool ventilation, the following should be taken into account:

• moist and heated air masses rush to the ceiling;
• Condensation forms on all cool surfaces.

Equipment for ventilation of any pool can be installed either in the adjacent room or under the bowl itself, around it, on top or on the wall. Often, supply grilles are placed around the pool or on both sides of it, facilitating the rapid displacement of exhaust humid air upward to the hood.

An important component in the operation of supply and exhaust ventilation of a pool is outside air. Its temperature affects the performance and power consumption of the system. In cold weather the air is cold and dry, in hot weather it is humid and warm. Thus, the ability to regulate air exchange allows you to create a comfortable microclimate without spending extra resources.

Adjustment is carried out using fans that increase or decrease the intensity of airflow and the volume of moving air masses. Manual or automatic control method is used.

Another important parameter for pool ventilation when calculating is the temperature of the supply air. It is heated by electric heaters before being supplied to the room, and correctly calculated temperature allows you to save on heating the room.

Features of designing ventilation for swimming pools in cottages

When designing ventilation for a swimming pool in a private house, the following features are taken into account:

• the water temperature in the pool according to domestic standards is +30 – 32 degrees, according to European standards +28;
• air temperature according to European standards exceeds the water temperature by 2 - 4 degrees, according to domestic standards by 1 - 2 degrees;
• the outflow of air can prevail over the inflow by 0.5 times;
• the noise level from operating installations should not exceed 60 decibels;
• As a rule, no more than 2 people swim in the pool at a time;
• use of the pool is occasional, not long-term;
• Blinds and curtains for water mirrors are widely used.

Used as pool ventilation equipment air handling units, can be separate, but always autonomous from the main air duct system of the house.

When placing supply grilles around the pool, discomfort is created from the movement of air masses, which is understandable, given small area premises.

It is advisable to use two-mode installations: the supply starts separately from the exhaust. When the pool is not in use, it is enough to ensure the outflow of moist air from the room.

Many customers require discreet ventilation in the pool that does not interfere with the design and architecture.

Selection of equipment and automation of pool ventilation

The selection of circuits and equipment for ventilation of a swimming pool in a cottage is based on careful calculations. Any factors that change the rate of evaporation are taken into account:

• pool area;
• temperature of water and air in the room;
• calculated humidity indicators;
• visiting mode;
• number of visitors;
• presence of water coverage;
• the volume of the hall in which the pool is located.

To calculate pool ventilation, data on average humidity and temperature in the cold and warm seasons is also required.

An automated control system allows you to set the necessary parameters once and never have to think about ventilating the pool of your private home. The electronics itself will determine the volume of inflow and outflow in case of changes in temperature or humidity.

Automation system capabilities:

• starting or switching off ventilation (at a certain time or depending on air characteristics);
• control over humidity and air temperature;
• protection of equipment from power surges;
• notification of equipment malfunctions;
• integration into the smart home system.

Pool air conditioners

Decorating a pool beautifully is a matter of delicate taste

This is the epitome latest technologies, allowing you to purchase equipment for pool ventilation with your own hands. Air conditioners for swimming pools create the required microclimate, are fully automated and operate in the following modes:

• Room heating. The built-in heat register allows you to warm up the air in the room where the pool is located;
• Air dehumidification. The process takes place in a heat pump, where the air temperature drops to the dew point and drops of moisture are deposited on the walls of the evaporator, flowing into a container for collecting condensate. Next, the air enters the heat exchanger and is warmed before being supplied to the room;
• Fresh air addition. This function allows the air conditioner to completely replace the pool ventilation circuit, supplying heated and filtered air into the room. Warming up occurs due to heat recovery from the removed air;
• Summer mode. If the ambient air temperature exceeds the room temperature, this mode starts;
• Enhanced dehumidification. This mode is included in the ventilation scheme of a private pool if desired. It is necessary in areas with high atmospheric humidity.

The air conditioner makes ventilation in the pool easy to control and install. For country house This perfect option. But there are also more powerful models for therapeutic or public pools. The technologies used allow us to minimize operating costs. The power of the fans, as well as the operation of all other components, is controlled by an electronic switch.

The air conditioning unit is protected from corrosion polymer material and insulated.

Control is carried out by a remote control equipped with a screen, as well as an additional remote control. The screen displays information about the temperature and humidity of the room. Many models are equipped with modems that allow remote control.

Such systems allow you to very accurately maintain the microclimate in the room, ensuring high-quality ventilation of the pool. The owner can choose the appropriate equipment with his own hands.

We work with Objects of varying levels of complexity. Ventilation in the pool of a private house is installed with no less quality and attention than in large public swimming facilities.

Basic requirements for the ventilation system of indoor swimming pools

In order for the serviced premises to be comfortable, it is necessary to ensure that the climatic indicators in it correspond to certain values. They are given in the documentation SanPIN, SNiP, GOST.

In our work we take into account all the requirements of norms, rules and standards. When the Customer's wishes go against them, we always strive to adapt these wishes and bring them into line with the requirements.

Below are some of the required values ​​of climate indicators:

Failure to comply with any of these conditions can lead to sad and negative consequences. For example, an increase in temperature above normal values ​​leads to the formation of additional moisture and its settling on building structures. Which can lead to the appearance of fungus and their gradual destruction.

Supply and exhaust ventilation in the pool should provide:

• Air exchange in accordance with regulatory documentation
• Maintaining air humidity within the required limits

Required data for calculation

To select a scheme and calculate the parameters of the pool ventilation system, the following data is required:

• Characteristics of the room (dimensions, layout, etc.)
• Material of enclosing structures and their structure
• Initial temperature and humidity conditions
• Required air exchange values
• Related engineering and its technical parameters
• Approximate route for laying tracks
• Client's wishes

Combating constant high humidity

A swimming pool is an area in which a constant increase in dampness is caused by natural processes - water evaporates from the water “mirror”. Evaporation is especially intense if there are fountains, Jacuzzis, water slides, or if there are always a lot of swimmers present. Since the room is closed, it is impossible to remove moisture to the outside without special technical means.

To maintain the necessary climatic conditions, there must be a supply of fresh air masses, their movement and release outside. The main task of pool ventilation is precisely this.

Each specific case, and each specific swimming facility requires its own individual solution. The system configuration cannot be “taken out of thin air.” It must be specifically designed and correspond to the tasks that it needs to solve. Any mistake is fraught negative consequences, both financial and more serious.

Schemes for solving drainage problems

The solution to the problem of dehumidification in premises of this type can be implemented according to three schemes:

• Ventilation system using a dehumidifier
• Ventilation system without a dehumidifier - in this case, dehumidification is performed by a ventilation unit with specially selected equipment and parameters
• Dryer only

Typically, ventilation in a pool is carried out according to a complex scheme, which includes:

• Ventilation unit
• Dehumidifier. It can be either separately located or integrated (channel). In addition to the air drying function, it allows you to solve another problem - partial air purification from dust and various impurities
• Heater. Its functionality is to heat the air masses coming from outside

The complex ventilation option is the most expensive. But, if implemented correctly, its use guarantees comfortable conditions in serviced premises. In addition, heating the incoming air flow can significantly reduce the cost of heating the cottage.

If ventilation in the swimming pool of a private house is planned using a water heater, then its power must be taken into account when calculating the power of the boiler room. If you plan to use a system with an electric heater, then the power of this heater affects the power supply. It must be taken into account when calculating the cottage's electrical network.

Use of dehumidifiers only

There are cases when it is impossible to install a ventilation system at the Objects in question. In these cases, a configuration is chosen for implementation in which the entire system consists of a single dryer.

The operating principle of the dehumidifier is as follows: moisture-saturated air is removed from the drying zone and cooled until the “dew point” is reached. The remaining excess moisture is removed in sewer system, and dry air again enters the work area. The disadvantage of this approach is the lack of fresh air.

It is necessary to understand that the use of this approach cannot guarantee complete dehumidification and bringing the air into compliance with the requirements of SNiP. When developing a project and constructing a building with a swimming room, this must be taken into account. And already at this stage it is constructive to plan a full-fledged ventilation system. The best option- production of the project ventilation system before the start of construction of the building.

Basic rules for installation and arrangement of elements

The development of a ventilation system for a private pool, as well as its subsequent installation, is carried out based on several basic rules. Some of them are given below:

Heat recovery

The main way to reduce the costs of creating and operating a ventilation system is to use a recovery scheme.

The principle of recovery is that the heat from the air removed from the room is used to heat the air entering the room. The flows of incoming and outgoing air are separate. There is no mixing of these flows, only heat transfer occurs.

During recovery, thermal energy is effectively utilized. However, it must be taken into account that recovery parameters require accurate calculation. Ventilation of a private pool with recovery, if not performed correctly, will not lead to the desired effect. On the contrary, it can cause an imbalance in the entire system.

The development and installation of a ventilation system in such a complex room as a swimming pool requires the company performing it to know the specifics and certain nuances. An unprofessional approach or low qualifications of the Contractor can lead to mistakes and negative consequences.

Pool ventilation from MosInzhGroup is a guarantee of professionalism at all stages of the work performed!

Recently, arranging your own pool in a private house or cottage is not an indicator of incredible luxury. Modern technologies allow you to install such a water tank indoors without huge costs and investments. In order for the structure to last a long time and for a comfortable microclimate to be present in the house, you need to take care of the ventilation of the pool in advance.

Show all

general information

Each pool is a huge container of water, which constantly evaporates and falls out in the form of condensation on the ceiling, window openings or wall structures. But where there is water, there is also fungus or mold.

Moreover, exposure to increased moisture negatively affects the durability of the pool itself, because it leads to destruction finishing materials and other deformation consequences. Among them:

• The appearance of rust on metal products.
• Development of fungal microorganisms.
• Swelling and destruction of plastered surfaces.
• The appearance of stains on painted parts.
• Deterioration of the insulation of conductive materials, which increases the likelihood of receiving an electric shock.

In connection with the above points, arranging ventilation for a swimming pool in a cottage - the most important stage, which must be treated with increased responsibility. Such equipment will save the room from various deformation processes, and will also extend the service life of the tank itself.

With good ventilation in internal space There will always be a certain humidity level present. This unit indicates the volume of water vapor per unit volume of air. If the humidity exceeds the permissible level, it becomes difficult to breathe in the room.

However, if the air is too dry, this also entails unpleasant phenomena. Therefore, it is important to achieve an ideal balance, guided by the operating mode of the structure, the climatic factor and individual preferences owners of the premises. Future calculations should be carried out taking into account air and water temperatures.

Pool ventilation



Indoor microclimate

IN construction industry There is such a thing as saturation humidity. This indicator characterizes the volume of water that is taken up by the air at a specific temperature. If the temperature starts to rise, it raises the saturation humidity level. If the permissible value is exceeded, the excess begins to turn into condensation and settle on wall structures, glass or the ceiling.




When arranging ventilation in the swimming pool of a private house, it is necessary to get rid of excess moisture evaporation, maintaining a specific balance between the temperature of water and air.

If the volumes of evaporated moisture are relatively small, then there is no need to buy powerful ventilation systems. If the temperature of water and air is kept at the same level, the saturation point will be comparable to 100% air humidity.

But to ensure a comfortable microclimate in a room with a swimming pool, it is recommended to maintain a humidity level of 50 to 65%. This requires the installation of a mechanical ventilation system.

There is another method to reduce the level of evaporation. It is enough to cover the surface of the water with special metal elements, like blinds. As is known, closed water practically does not go into the evaporation stage and does not cool. If we compare an outdoor pool, about two and a half liters of liquid can evaporate in an hour. IN closed type these figures are 1.2 liters per part. As a result, this approach guarantees greater resource savings.



Reducing humidity in the room

Even the most powerful pool ventilation project is not able to completely cope with the problem of high humidity in the room. However, it is quite possible to reduce the level of evaporation, since there are many tools and ventilation equipment for this. Recently, supply and exhaust ventilation for pools, which is combined with the installation of special dehumidifiers, has been in particular demand.

When entering the dehumidifier, the air is heated to its dew point, which leads to moisture condensation. Then it heats up additionally and returns back, but in pure form, no water particles. Such systems are relevant for cottages in which it is impossible to consider the option of installing an inflow-outflow system. The design includes a hygrostat, which causes the compressor to start at certain operating conditions. If the moisture level decreases, the humidistat stops the compressor while the ventilation blades continue to rotate.

Condensation dryers available on the market are divided into several types:

1. 1. Wall-mounted. They are located in buildings where there is already finishing work.
2. 2. Wall hidden. In such dehumidifiers, all working elements are securely hidden in separate room, and in the space with the pool there is only a fence grille. You need to start planning such a scheme long before arranging a water tank.
3. 3. Stationary, non-removable. Such installations are characterized by the highest power and require additional space. They are often included in the supply and exhaust ventilation system in large sports centers. Stationary models support the mixing of 1/5 of the air volume, and if you equip them with a duct heater, this will allow you to set up a full-fledged ventilation system at home.



Moisture assimilation

In the search for effective ventilation systems in the pool, schemes and structural designs, one cannot ignore the method of moisture assimilation in the pool. It involves using the natural property of air to absorb water vapor. The technology allows for 5-fold air exchange in one hour of operation.

In temperate latitudes and in houses with small swimming pools, a conventional ventilation system is sufficient. But if we are talking about large water tanks in gyms and entertainment complexes, then here it is necessary to additionally equip a multifunctional dehumidifier.

An indisputable advantage of moisture assimilation is the effective elimination unpleasant odor, which appears due to high humidity. As for the minuses, there are few of them. The most unpleasant moment is the dependence on weather conditions, because if the surrounding air is too humidified, it will not be able to absorb condensation from the room with the pool.

But in most cases, this scheme justifies itself and outperforms other solutions. Another disadvantage of assimilation is the need to warm up the supply air. The procedure is especially necessary during cold periods, when the heating process requires a lot of electricity.

Engineers also practice combined method drainage of the pool, which is in demand for large areas and swimming pools with high frequency visits. In this case, you have to combine a dehumidifier and a forced ventilation system.

In this case, the type of equipment can be independent or form an irreplaceable part common system, affecting the microclimate. Combined options They are expensive options and are justified only on an area of ​​50 square meters or more.

How to reduce humidity in a swimming pool? Pool ventilation

Temperature maintenance

To avoid excessive moisture release, at the ventilation design stage it is necessary to achieve such indicators that the temperature in the building with a swimming pool exceeds the ambient temperature.




This is only possible if you have a powerful heating system that heats the air to optimal performance. But ventilation is not capable of heating the building, so air heating may be ineffective. It justifies itself only when additional installations are installed.

If the building is characterized good glazing, and the pool is located in a southern area, it is impossible to do without installing a powerful air conditioning system. Regarding frequently visited swimming pools with large sizes, then natural ventilation systems in them may be useless. In this case, forced methods of air movement are used, demonstrating the following advantages:

• Maintaining a stable temperature.
• Constant supply of fresh air.
• Fighting unpleasant odor.

Swimming pool in a private house. Heating system in the pool, ventilation and water heating.

Supply and exhaust circuit

Considering the most best types ventilation systems for the pool, one cannot ignore the example of the supply and exhaust circuit.





It has the following advantages:

• Stable flow of fresh air.
• Fighting residual moisture in the atmosphere.

The device is equipped with a special air dehumidifier, and any heat is instantly removed outside. In addition, such a system is characterized by autonomy and can operate without exposure to air from other rooms. Ventilation ducts are made on the basis of moisture-resistant materials, and the equipment is controlled using advanced automation. As a result, this allows you to maintain a stable temperature regime and introduce clean air.

Before entering the room, street air is carefully filtered, cooled or heated. Its humidity indicator also changes.

Correct design of the system in the cottage

To make a cottage pool worth it, there are a few things you need to keep in mind.

First of all, you should make sure that the temperature regime is kept within 30-32 degrees Celsius, and the outflow of air prevails over the inflow by 0.5 times. Noise levels cannot exceed 60 decibels, and no more than two people should be in the pool at the same time.

In order for the design and installation of an air exhaust system to be as successful as possible, you need to take into account a lot of rules and recommendations. You should visit a special website where you can calculate the required parameters online. Planning a ventilation system will only be successful after consulting with an expert and taking into account several important points.




As is known, the air high humidity and at elevated temperatures it is constantly directed upward, and when it collides with a cool surface it turns into condensation. In this regard, ventilation equipment can be located both in the adjacent building and under the bowl, around it or on top. In many cases, such systems are placed around the pool or on both sides of it, which causes the rapid displacement of exhaust moist air.

To ensure a comfortable microclimate in a building with a swimming pool, first of all drafts must be prevented. To do this, it is enough to equalize the volumes of supply and exhaust air. In the place where visitors are located, the air should not move faster than the specified speed. Often the intensity of movements is reduced using various patterns or specific grids.

Air supply channel It's better to place it near the windows. It is also desirable that it be made of good heat-conducting material. Under the influence of dry air, any condensation will stop settling on the glass, and upon contact with the window, warm air will begin to cool.

Box with hood installed directly under the ceiling where intense accumulation of moisture and heat is observed. Otherwise, the air will quickly escape. If available in the building suspended ceilings, you need to think through the ventilation system in advance. If you do not do this, an area with high moisture content will appear above them.

A properly equipped air exchange system in a room with a swimming pool is the key to successful and long-term operation of such a water tank.

Therefore, in order to extend the life of the pool and protect it from premature deformation, it is important to design and install ventilation equipment in a timely manner.

Pool ventilation is designed to maintain an acceptable climate, as in any other room. However, the main emphasis is on controlling humidity and temperature levels. Having provided these two parameters, all other conditions are additionally satisfied.

Standards for air parameters

Pool ventilation must provide a number of parameters that together will create comfortable conditions for a person to stay in this room while undressed, among them:

• humidity level not higher than 65%;
• air temperature not exceeding the water temperature by more than two degrees;
• the water temperature is kept at no more than 32 degrees;
• the speed of air flow should not exceed 0.2 m/s (a value of 0.5 m/s will already be noticeable to a person);
• when the ventilation of swimming pools is designed, it is allowed to use the calculated air exchange value, however, it should not be lower than the standardized value - 80 m3/h per person.

Normative documents also determines the permissible difference in the volumes of supply and exhaust air, which is half the air exchange rate for a given room. But it should be taken into account that the value of this parameter is taken taking into account the speed of air flow.

The design of pool ventilation is based on the choice of a forced type of system, since natural air circulation cannot provide the air parameters required for an indoor pool due to the rather large area and constantly filled pool bowl.

The pool ventilation design should also take into account general level noise emitted by operating equipment. Taking into account the area of ​​the room, equipment is selected with high productivity. The total noise effect must not exceed a threshold of 60 dB.

Project development features

Designing swimming pool ventilation involves taking into account not only the ability to provide effective air exchange, but also eliminating the formation of factors harmful to the equipment. The first of these is condensation, which falls on the surface of the ventilation shaft, which will lead to its rapid wear. For this purpose, internal or outer surface ventilation shafts are insulated and electrically heated valves are used. Trays for collecting condensate are also required.

The ventilation of a private pool, just like the system of a public one, should provide for the possibility of using equipment of slightly lower productivity during the downtime of the room when it is not in use. And additional devices with higher power will turn on when the pool is in use. Thus, there will be no excess consumption of electricity when servicing the premises around the clock, but it will be achieved required value air exchange. Ventilation in the pool of a private house to a greater extent requires such an approach to organizing the operation of the equipment, since the frequency of use of this room is an order of magnitude lower than that of a public one.

When choosing devices that will supply and remove air, it is necessary to take into account the area of ​​the room, the calculated values ​​of the air exchange rate and air flow per person, as well as the possibility of heating the room.

Supply and exhaust ventilation in a pool can solve all problems, as it contains several components: a filtration system, a heater, a fan. If desired, you can choose monoblock installation with recovery, since this device will help reduce energy consumption by a quarter. The pool is provided with water heating, preferably along the entire perimeter of the bowl.

The ventilation system is equipped separately from the main one. It is advisable to plan a pool in a separate or adjacent room to the main building. When installing pool ventilation with your own hands, the so-called curtaining of the pool bowl is often used, which will help reduce evaporation from the water surface and the release of moisture into the air.

Basics of ventilation system calculations

Humidity levels up to 65% are allowed. However, in practice, a decrease in this parameter to 50%, and sometimes below 45%, is often observed. The feeling of excess moisture in the air plays a role here, since even if the supply ventilation in the pool and air exhaust are organized correctly, providing a fairly high percentage of humidity, discomfort may be felt and condensation may appear on the walls of the room.

When designing pool ventilation, the calculation includes determining the air flow. Using tables, air exchange is determined at a given temperature and a certain area of ​​the pool bowl. For example, if the pool area is 32 m2 and the room temperature is 34 degrees, the air flow is approximately 1,100 m3/h. The heater power should be about 20 kW.

The calculation of the pool ventilation system takes into account a number of parameters, including:

• area of ​​the pool bowl;
• area of ​​bypass paths;
• total area of ​​the room;
• outside air temperature during warm and cold periods;
• water temperature;
• indoor air temperature;
• the number of people regularly visiting the pool;
• Taking into account the peculiarity of air movement in the room (warm currents rise upward), for the calculation it is also necessary to know the temperature of the air being removed from the upper zone.

If you design the ventilation in the pool yourself, the calculation should include a number of calculations:

1. Receipt of sensible heat (heat release from solar radiation, from swimmers, from bypass paths, from lighting, and also when heating the water in the pool).
2. Moisture entering the air (from swimmers, from the water surface, from bypass paths).
3. Air exchange by moisture and total heat, as well as standard air exchange, are calculated.

Based on these data, you can adjust the project by adding equipment to further reduce the supply air temperature in the hot season, and in the cold season, on the contrary, more may be required. powerful device to heat the air environment than was originally intended when designing the ventilation system. When designing swimming pool ventilation, a calculation example will help you navigate the actions that need to be performed. For this purpose, tables are also used, through which you can obtain a number of normalized values ​​based on the specified parameters.

When deciding to build a swimming pool, it is necessary to take into account all the factors that influence a comfortable stay in the room. To correctly calculate the pool ventilation systems, you will need to study all the equipment and structures in the complex. Namely: mirror area, location of water treatment systems, door and window openings, type of bowl (skimmer, overflow, etc.), room design (wood, concrete, brick), presence of adjacent rooms (bath, sauna, hammam, etc.), availability basement for supplying fresh air, the presence of a drainage system, etc.

Competent calculation of the ventilation system, installation necessary equipment, adjusting its functioning is an important factor influencing the creation of a comfortable microclimate in the room. Lack of attention to these details leads to unpleasant consequences.

Pool microclimate

The pool ventilation system is extremely important factor creating a microclimate that is comfortable for humans. The lack of a high-quality ventilation system leads to the rapid spread of fungus and mold, and the accumulation in the air large number microorganisms lead to various diseases.

High humidity in indoors pool leads to metal corrosion and rotting wooden structures, destruction of finishing and walls by fungus

The humidity in the pool room should be at the level of 50–60%; in this case, a moderate level of moisture evaporation from the surface of the water is achieved, which affects the comfort conditions in the room. At a given humidity and air temperature of 28-30 °C (characteristic temperature for swimming pool premises), dew will form at 16-21 °C. This is noticeably higher than for ordinary rooms, in which the air temperature is 24 °C, humidity is 50%, and the dew point is 13 °C. For swimming pool premises, excess moisture content in the air is considered normal.

• The water in the pool is within 24–28 °C.
• The air in the pool room should be 2–3 °C higher than the water temperature. When the air temperature drops, there is a risk of catching a cold. As humidity increases, a feeling of stuffiness may occur. It is also not recommended to reduce the air temperature at night in order to save energy, as heat consumption increases.
• To avoid drafts, the recommended air speed should be in the range of 0.15–0.3 m/s.

All these and many other conditions are taken into account during the design, and solutions are proposed to reduce moisture condensation on the ceiling and walls. The complexity of the situation is that when people, for example, do not use the pool at night, the heat and humidity do not disappear. The pool cannot be “turned off” at night. The only way to reduce the amount of evaporation is to use water surface covers, but these devices are short-lived and rarely used.

When the humidity level reaches 80–90% at a temperature of 29–30 °C, there is a risk of exacerbation of chronic diseases and a sharp deterioration in well-being. Therefore, with a correctly calculated and designed ventilation scheme for a private pool, excess moisture is removed from the air, it is cleaned due to intensive air exchange, but does not dry out.

Air is dehumidified to the required parameters by dehumidifiers, according to moisture release parameters. Dehumidifiers can be monoblock and built into the ventilation system (at ).

An example of calculating the evaporation of water from a swimming pool per day

Initial data:

• Mirror size 4.2 × 14 m.
• room temperature +28 °C;
• pool water temperature +26 °C;
• relative humidity 60%.

1. The surface area of ​​the pool is 58.8 m².
2. The pool is used for swimming 1.5 hours a day.
3. The evaporation of water during swimming will be 270 grams/m²/hour x 58.8 m² x 1.5 hours = 23,814 grams.
4. Evaporation at rest for the remaining 22.5 hours will be 20 grams/m²/h x 58.8 m² x 22.5 hours = 26,460 grams.
5. Total per day: 23,814 grams + 26,460 grams /1,000 = 50.28 kilograms of water per day.

Ventilation design rules

The ventilation system installed in the pool must be autonomous and independent of the ventilation of the rest of the house. If the ventilation of a house must ensure the flow of fresh air and the removal of waste air masses, then the ventilation of swimming pools, in addition to these functions, must maintain the relative humidity of the atmosphere within the established standards.

When constructing a pool, the project is developed individually. The main requirement is to ensure the safety and comfortable stay of people indoors.

In order for swimming pool ventilation units to work effectively, it is necessary to design their installation taking into account:

• Size of the room.
• Number of people using the pool.
• The area of ​​the water surface of the pool.
• Air and water temperature requirements.
• The rate of evaporation of water, which depends on its temperature. The warmer the water, the faster it evaporates.

Taking into account these parameters, the appropriate power of supply and exhaust ventilation for the pool is selected. If the equipment is chosen incorrectly, this will lead to an imbalance in air humidity and temperature. This will contribute to condensation settling and creating an unfavorable atmosphere for human health.

Pool ventilation diagram

The calculation of ventilation in the pool is carried out taking into account two features:

1. Heated moist air currents rush upward.
2. Condensation settles on all cool and damp surfaces.

Ventilation equipment can be installed in any convenient way: on the walls, on top of the pool, under its bowl or around it. Often, supply ventilation is located around the pool or on both sides so that the exhaust air rises faster to the hood.

The exhaust unit must operate so that the volume of air it removes is equal to the volume of supply air masses. Thanks to this functioning, there will be no drafts that disturb the comfortable microclimate. Supply ventilation It is recommended to install under windows, air is supplied from the basement through slotted floor grilles. This placement of ventilation ducts will prevent the formation of condensation on the glass. Exhaust ventilation ducts are mounted in the middle of the mirror under the ceiling where moisture and heat collect, not getting close to the inflow, so that the recirculation of air masses is more efficient.

Ventilation calculation

To design the right ventilation system, professionals recommend dividing the installation process into several stages:

1. Selection of equipment and materials for installation of the ventilation system. At this stage, you should decide on your choice good specialist who will perform the work.
2. Creation of a working draft, design of a circuit for installation with the installation of the necessary technological holes.
3. Creation executive documentation, including drawings and instructions for installed equipment.

Determination of ventilation performance and air heater power depending on the surface area of ​​the pool

Here's an example of how to calculate pool ventilation:

• Temperature values ​​are taken as the initial data working area premises, water in the pool bowl, humidity level, bowl area, as well as average daily temperature and air humidity.
• The air exchange is calculated for the number of people using the room. The air exchange rate is calculated using the formula: the evaporation rate is divided by the specific density of the air, which is multiplied by the difference in air humidity outside and inside the room. For 1 person it is 80 m³/h, therefore for 10 users this figure will be 800 m³/h.
• The supply air flow rate is determined to maintain the optimal humidity level (for example, in the initial data it is 60%). It is compared with the air exchange rate presented above. The larger of these values ​​is selected.
• The level of heat gain and loss is determined. Heat comes from lighting, swimmers inside the room, attached rooms (bath, sauna, hammam), density of bypass paths, door and window openings. Heat loss occurs when the reservoir heats up.
• Then the amount of evaporation from the surface of the reservoir is calculated. The evaporation coefficient is determined.

Having calculated all the indicators, we can conclude how many degrees the incoming air should be cooled or heated in order to maintain a balance with the temperature inside the room.

Optimal humidity level

A comfortable level of air humidity in the pool should not exceed 65%. To reduce humidity to the optimal level, you can use a dehumidifier, forced-air ventilation, or both. Two methods are used to dry air: condensation and assimilation:

1. Condensation is a method in which air is passed through a dehumidifier where its temperature reaches its dew point. After moisture condenses, the air warms up and returns to the room. In this case, thermal insulation of all air ducts is necessary to prevent condensation from draining inside the room. Often, the pool ventilation in a cottage with such an installation is equipped with a hygrostat, which starts the compressor when the humidity reaches a certain level. When the humidity drops, the compressor automatically switches off. The fan continues to work. There are condensation dryers three types: wall-mounted, hidden, stationary. The last type requires separate room or built into the supply and exhaust system.
2. The operation of supply and exhaust devices according to the principle of assimilation is based on the ability of air to absorb water vapor. The advantage of the assimilation method is that it effectively purifies the air, but there are two disadvantages. The first is related to weather dependence: when high level atmospheric humidity, the air entering the pool room does not absorb moisture. The second disadvantage is that the supply air must be heated.

The rate of water evaporation from the pool surface (liters/square meter per hour)

The best option for maintaining required level humidity of the pool room, experts consider a combined dehumidification method using a forced installation and a dehumidifier. However, this method is effective only for small bowl volumes, and requires careful calculation, otherwise problems may arise in resolving the issue (equipment failure, inexperienced connection of the system, etc.).

Ways to maintain optimal air temperature

The air temperature in the pool should be higher than atmospheric. Heating systems are often used for this: the supply air is heated to a temperature that is maintained by the heating system using appropriate sensors, which increases the cost of the project. This method is best used as an additional method to the main one. heating system. Most effective way maintaining optimal temperature air in the pool is supply and exhaust system with heat recuperator. It takes heat from the exhaust air (35–40%) and gives it to the cold supply air through filtered systems. It must be remembered that the heat of the return air is not enough, and in any case it is necessary to install additional heating (electric heater, water heater).

To summarize, it should be noted: to create favorable microclimate inside the pool room, it is necessary to carry out a complex process of calculations, design, and installation of ventilation systems. But the efficiency of the ventilation system is influenced by many factors, between which a certain balance must be maintained, corresponding to the standards of air exchange, optimal humidity levels, and air temperature.

This process requires professional approach to the ventilation system for rooms with a swimming pool:

• The supply and exhaust ventilation rate is calculated based on specific individual conditions.
• The air dehumidifier is selected according to the parameters indicated above.
• The presence of a specialist is required.
