Fresh and clean air is important for comfortable breathing at every moment of being inside indoor pools. Swimming pool ventilation systems are installed to regulate and balance air humidity and ventilation conditions for indoor swimming pools, and creating ventilation for swimming pools will vary according to the device model and how they work, which you can check for technical specifications, brands, And the price of buying all kinds of pool ventilation equipment, stay with us in the rest of the article.
Guide to choosing pool VENTILATION systems
An important issue considered in the initial stages of designing and building pools is whether the pool is covered or open. As a general rule, both in soldier pools and indoor pools, the employer's ultimate goal is that the pool can be used most of the year. In tropical regions, swimming pools and water parks are usually built in the form of soldiers, and the favorable conditions of their environment are provided based on the region's weather conditions.
air temperature
relative humidity (RH)
airflow
Hall air quality
Due to the humid environment in indoor swimming pools, the mentioned four factors should be provided considering relative humidity, air temperature, pool water temperature, and indoor air quality. Among the factors mentioned, relative humidity is more problematic and important than others. Because the high relative humidity of the air threatens the comfort and health of swimmers while breathing and causes irreparable damage to the building structure and equipment in the long run, therefore, the ultimate goal of the designer should be to provide the following conditions:
Comfort conditions for swimmers and provision of a healthy environment for them
Controlling the relative humidity of the air in the hall
Providing the desired indoor air quality
Water vapor distillation control inside the pool
Buying pool ventilation systems
The first point that should be mentioned is that except for the championship swimming pools with special stands for spectators, air cooling systems are rarely used in other swimming pools to cool the interior. The reason for this issue is also clear; as long as people are swimming inside the pool, the pool water acts as a medium for heat transfer and takes the heat of the swimmers' bodies to some extent. The body reaches a state of thermal equilibrium. When the swimmer gets out of the water, even with the slightest breeze, people shiver because the water evaporates on the skin as the air flows.

The human body is very sensitive to changes in relative humidity. Fluctuations in relative humidity outside the range of 40 to 60 percent increase the possibility of bacteria, fungi, and mold growth, which decreases the air quality inside the pool. For people who swim in the pool, the 50 to 60% humidity will bring the most comfort. If the relative humidity is less than 50%, the rate of evaporation of water from the skin surface will increase, which causes an unpleasant cold feeling for swimmers. They may have just come out of the water, and their bodies are still wet. Relative humidity of more than 60% also increases the possibility of fungi and molds growing in the pool hall environment, the rate of water vapor distillation on the internal surfaces, and the destruction of the structure and equipment in the pool hall. In all indoor pools, the relative humidity is kept in the range of fifty to sixty percent for the following two reasons, and it is usually not reduced below fifty percent:
In relative humidity less than 50%, due to the rapid evaporation of water from the skin, swimmers who get out of the water feel unpleasantly cold.
Regardless of other factors, in swimming pools, due to the constant evaporation of water from the pool bowl and very humid conditions inside, reducing the relative humidity of the indoor space below forty percent requires spending a lot of money. At the same time, relative humidity above 50% is possible by spending reasonable and acceptable costs.
Factors for calculating water evaporation rate in swimming pools
The free level of pool water: the higher the pool level, the higher the water evaporation rate. Of course, it should be noted that factors such as depth, shape, and total volume of pool water do not affect the evaporation rate of pool water. But the free surface of the water in contact with air is effective.
Pool water temperature: The pool water temperature and its mutual effect on indoor air temperature are among the most effective factors in terms of the total rate of water evaporation. As the air temperature of the pool decreases compared to the water temperature, the water evaporation rate increases significantly.
Pool air temperature: To minimize the rate of water evaporation, the pool air temperature should be a few degrees higher than the water temperature. To reduce the evaporation rate of pool water and prevent the induction of cold feelings in the body of people in the pool, the air temperature in public pools should be kept 1-2 degrees Celsius higher than the water temperature. In swimming pools, two thermostats are used to control the temperature of the swimming pool. So that one thermostat is used to control the air temperature of the pool, and another thermostat is used to control the water temperature. The thermostats that are used to control the water temperature are called acoustics.
Relative humidity of indoor air: as a general rule, keep in mind that the lower the relative humidity of the pool air, the longer the pool's air conditioning system will have to work, which will increase the running costs of the system. When the air and water design standards of the pool are met, exhaust fans can be used in addition to the air conditioning system of the main pool to remove the extra heat from the interior space.
Airflow on the surface of the water: One factor that increases the pool water's evaporation rate is the wind speed in military pools and the airflow that passes over the surface of the pool water in indoor pools. By reducing the airflow that passes directly over the water surface, the rate of water evaporation also decreases.
The amount of water turbulence and swimmers' activity coefficient among the mentioned factors, the relative humidity of the air is more problematic and important than other cases because the high relative humidity of the air not only deprives the swimmers of their comfort but in the long run, irreparable damage to Imports structures and equipment. The main reasons for the increase in pool water evaporation and relative humidity in the pool hall environment are the large temperature difference between the pool and ambient temperatures. This temperature difference should be at most 2 or 3 degrees Celsius; also, if the relative humidity of the environment is less than 40% to 50%, the swimmer will feel cold.
Moisture removal methods
Dehumidification using moisture-absorbing salts (moisture-absorbing salts such as silicates have a very high tendency to absorb moisture. After absorbing moisture, these salts reach a saturated state and lose their ability to absorb, and must be reused to revive them somehow.)
Dehumidification using cold surfaces (mechanical dehumidification systems)
