Correct methods for calculating the ventilation system in the pool

Pools are available for public and private use. Each type has its own requirements for characteristics. Regardless of the purpose, the facility must have a ventilation system. It provides standard room air parameters, optimizes energy consumption depending on the microclimate. The design and creation of the pool ventilation scheme must comply with all the requirements.

Purpose of ventilation in the pool

A pool is an object in which there is constant intense evaporation from the surface of the water. It leads to an increase in humidity, which can lead to the following negative consequences:

• Condensation build-up on windows and other building structures. Excessive moisture can damage them and can also cause mold.
• Violation of sanitary standards. Discomfort of people who are relaxing in the pool.

The main task of ventilation in the pool is to maintain optimal humidity, temperature and air renewal.

Ventilation is designed during the construction phase of the pool. In this case, it is easier to install the channels.

Creation of a ventilation system plan

Designing a ventilation system in a swimming pool is a complex task, in the solution of which it is necessary to take into account all the nuances and features of the object. The basic requirements contain a description of the object itself:

• Placement relative to ground level. On which floor is the pool installed. The best choice is to create an object in the basement or on the first floor of the building.
• Orientation to the cardinal points.
• The presence or absence of coverage.
• The number of swimmers. Bathing frequency and time.
• The presence of sources of heat and cold.
• Air dehumidification methods.

The ventilation system is responsible for maintaining the required values ​​and parameters of the air in the room and optimizes the consumption of energy resources in case of changing conditions.

Determination of area

Public swimming pools have strict requirements for determining the area. Private owners can use approximate calculation formulas.

The traditional or normative way is as follows. It is necessary to take the number of swimmers, which is approximately equal to 1/3 of the number of people in the pool. Each swimmer requires a minimum of 2 sq. M. water mirrors. From this data, you need to calculate the total area of ​​the mirror.

A different calculation method is used more often. The formation of the area and shape is determined by architectural and design ideas. According to these requirements, the design specification is formed.

Regardless of the chosen methodology, the design of the ventilation system is carried out after the choice of the shape, calculation of the mirror area, installation of paths and fences.

Air temperature calculation

A comfortable microclimate must be maintained in the pool. On average, the surface temperature is 1-2 degrees higher than the water temperature. Moreover, it should not exceed 35 ° C.For recreational pools, the temperature range is 29-32 ° С, for children, these readings are 30-34 ° С. A strict calculation of air exchange in the pool for private use can be omitted - use these indicators.

Automation should be installed in the room, which will react to changes in values ​​and, if possible, reconfigure the mode.

Moisture calculation

When calculating the relative humidity of the air, take into account:

• 50-65% - values ​​for the halls of the pool baths according to SNiP;
• 67% and 29 ° С for heat engineering calculations.

For a pool with an air temperature of 29 ° C, a relative humidity of 65%, it is necessary to create conditions under which the dew point for structures and floors, equal to 21 ° C, will not be reached or will be below this value.

Calculation of moisture release

The pool is an object in which there are constant sources of high humidity. These are emissions from the surface of the water and bypass paths, fresh outside air, moisture emissions from people and water attractions.

Discharge from the surface of the water should be taken into account in time and mode. When the object is not in use, moisture reduction can be eliminated by using shutters.

Calculation of air mobility

The speed of movement of air flows in private pools in cottages should not exceed 0.2 m / s. If the indicator is exceeded, moisture leaving the surface will increase, as well as discomfort for vacationers.

Calculation of the frequency of air exchange

Within an hour, a certain amount of fresh air passes through the room. The number of times is called the rate of air exchange in the pool. This indicator is provided by regulatory documents and is determined taking into account moisture release, evaporation area, emission intensity factor and air flow rate.

According to SP and SNiP, the outdoor air consumption should not be lower than the set values. For one person, the minimum value is 80 cubic meters per hour per swimmer and 20 cubic meters per hour per spectator.

Choosing the right equipment

Since the pool is a complex object with a high level of humidity and significantly differs in its microclimate from other rooms, a special ventilation system is chosen. There are special designs of housings and performance of elements that are designed to work with high humidity. Also, all parts must be resistant to the admixture of vapors of chlorine compounds. To increase the efficiency of ventilation, various recuperators, recirculation units, pool hoods, and systems for using waste heat are used. Thanks to such devices, you can use the heat to heat water to a comfortable temperature or other household needs.

A ventilation unit for a pool will cost more than for houses and apartments due to the use of reliable and durable materials that are used to work in water. There will also be costs for installation, ventilation maintenance and electricity to run the pump.

Features of creating projects for private pools

In any house, the pool is built according to an individual plan with a unique design. Regardless of the chosen scheme, it is important to strive for maximum human comfort from the point of view of physiology and psychology, since the object is a recreation area.

There are a number of guidelines to follow:

• Moist air should be removed from the upper area. It is lightweight so it can be easily removed with a hood above the pool.
• To ensure the specified rates of circulation of air masses, the area of ​​the ventilation grilles must be large.
• Better displacement ventilation. There must be a source of fresh air.

Floor and wall inlet grilles at the bottom can cause discomfort to vacationers.They will feel the movement of cold air, so it is better to place them in the upper part of the room.
