room, which houses the swimming pool, is adversely affected by high humidity.Excessive moisture settles on the ceiling, floor, windows, walls, metal structures and leads to corrosion, mold, bacterial growth and destruction of interior decoration.Water vapor has a negative impact on the equipment used, the result is a reduction in the operating system processing resource pool.In addition, create unfavorable conditions for the people present.To ensure a favorable climate in the room and the pool comply with sanitary norms applicable specialized equipment: forced ventilation and air dryer for pool .

Maintaining optimal humidity level is only possible when using these methods in combination.


Ventilation systems for pools ↑

main objective of ventila

tion is to remove excess moisture in the indoor pool.It evaporates from the surface as the pool, and with the wet fence, tel bathing people.In this situation, forced-air ventilation basin is a prerequisite for its functioning.

Important!Supply air shall not blow the water surface, since this causes an increase in the evaporation of water and its rapid cooling of the pool.

At design of the ventilation system should be aware that in order to reduce evaporation from the surface of the pool should ensure that the room temperature is 2-3 degrees higher than the current water temperature.Relative humidity is best maintained at 55-60%.

In practice two methods by which the supply and exhaust ventilation of pools:

  • Separate system and extract ventilation, which function simultaneously;
  • Supply and exhaust system with heat recovery.

Separate Ventilation and air extraction ↑

Separate system is characterized by a complex operation of supply and exhaust ventilation systems.Application of this method is different cheaper cost of the equipment, but is characterized by relatively high operating costs.To organize such a ventilation system for a swimming pool requires a large area for the installation.

This system supplies fresh air from outside and the simultaneous removal of humid air from the room by the pool.The device ventilation equipment is carried out with the construction works.

exhaust system provided an exhaust fan, built-in special exhaust channels.

Ventilation system consists of the following elements:

  • device for air intake valve, do not let the cold air in the winter when the fan is switched off;
  • filter to purify the incoming air;
  • heater outside air used during the cold season;
  • paranasal fan for organizing air supply into the room the pool;
  • control unit regulating the temperature and air volume.

important point requiring attention in the design of the ventilation system, it is the availability of the automation system.It is able to continuously monitor the room temperature and keep it at a certain level, controls the differential pressure between adjacent rooms and a swimming pool, ensures compliance with the required parameters of air flow.

Supply and exhaust system with heat recovery ↑

Air handling system with integrated heat recovery functions in one unit.This method differs the high cost of equipment procurement phase, but operating costs will be lower than for a cheaper separate air handling system.

Supply and exhaust system with heat recovery
Supply and exhaust ventilation system with heat recovery:
1 - fresh air;2 - exhaust air;3 - out of the pool;
4 - the pool

indisputable advantages of its use are:

  • Save space in the room.Supply and exhaust system in a single unit, requiring less space to accommodate than the separate system.Currently it plays an important role in choosing a ventilation system for a small pool.
  • energy savings.Using a built-in heat exchanger system can achieve energy savings of up to 50-70% due to the fact that the heating of the supply air using the exhaust air flow, but the mixing takes place.This function allows you to reduce the power of the engine built by 2-2.5 times.

The main elements of this system include:

  • Supply and exhaust fan;
  • purifying filter for the outside air;
  • dual valve prevents penetration of cold air when the unit is off;
  • heat reclaimers;
  • heater to preheat the incoming air to a predetermined temperature, located behind the heat exchanger.

uniform forced-air system is equipped with automatic control of temperature and humidity levels, in addition, it can further be equipped with devices for the distribution of hot air into other rooms.

to create and maintain the ideal climate should use additional specialized equipment such as dehumidifiers for swimming pools.

Dehumidifiers for pools ↑

main purpose of dehumidifiers is borrowing indoor pool optimum moisture.

Using dehumidifiers for swimming pools can significantly reduce energy consumption for heating outdoor air, as the bulk of the moisture can be removed using this equipment, avoiding its mechanical removal with air.The main drawback of using only the dryer becomes the inability to remove unpleasant odors.This problem is easily solved by a shared ventilation.

A variety of modifications can select dryer for pool based on the specific use case.There are stationary and portable, floor and wall models.

main parameters in selecting a quality dehumidifier are efficiency, performance, reliability, high protection against moisture.The main elements of this equipment is made of corrosion-resistant materials.

Current models of dehumidifiers for swimming pools operate on one of the following principles:

  • condensation;
  • Assimilation;
  • Adsorption.

condensing principle of the ↑

process works dehumidifiers, based on the principle of condensation, is located in the cluster of water vapor in the air on a special surface, characterized by a lower temperature.The mechanism of action is the same as that of the air conditioner, but the heat from the room is displayed.

principle of the device is the following: the interaction of air with the cooled surface of the condensation is carried out.Fan directs moist air from the pool room to the evaporator, where it is cooled and moisture condensation, which is then removed in a special container or through drainage.Further, air enters the condenser and heated to a predetermined temperature and falls back into the pool room.Dehumidifier is automatic.

Condensation principle of operation
Condensation drainage:
1 - moist air;2 - filter;3 - evaporator;4 - tray stacks;5 - container for condensate;6 - dried and cooled air;7 - capacitor;8 - Fan;9 - dehumidified and heated air

Efficiency condensing dehumidifiers is largely dependent on the initial room temperature.

Dehumidification by adsorption ↑

Work adsorption dryers is to remove moisture from air masses with a special absorber - adsorbent.The air in the room, forcibly passes through the desiccant chamber that contains the adsorbent.Further, moisture absorption is carried out effective adsorbent on the basis of fiberglass and return to the pool room treated air.

The adsorption principle of the
Adsorption dehumidifying:
1 - filter;2 - moist air;3 - a rotor;4 - dry air;5 - the fan;6 - regeneration air;7 - heater;8 - hot regeneration air;9 - humid regeneration air

data pool dehumidifiers are characterized by high efficiency and performance.The design of the rotor allows simultaneous adsorption miss two parallel air flow.One stream is processed and sends dry air into the room, and an additional stream of hot air removes moisture from the adsorbent.Continuous rotation of the rotor provides continuous dehumidification of humid air and the simultaneous recovery of the adsorbent.

Assimilation dehumidifier ↑

dehumidifiers, using the principle of assimilation, are characterized by low productivity and efficiency, consuming energy.Assimilation principle consists in the fact that the heated air to intervene more water vapor than cold.This kind of dryers is practically not applicable for drying basins, as their operation is largely dependent on ambient temperature.The assimilation dryers do not provide effective results in rooms with high relative humidity.

When choosing a dehumidifier is necessary to pay attention to the vibration and noise during operation.These parameters have an important influence on the comfort of the people present in the pool, because the equipment is designed for continuous operation without shutting down.

With proper organization of the pool ventilation and dehumidification creates favorable conditions for the people present, increases the life of the building as a whole.Using the full range of activities can achieve the required fresh air and avoid high humidity.Creating a favorable climate in the basin is only possible when the perfect balance between the air temperature and humidity.
