Ventilation and air dehumidifiers for swimming pools
The room, which houses the swimming pool,It is adversely affected by high humidity. Excessive moisture settles on the ceiling, floor, windows, walls, metal structures and leads to the formation of corrosion, mold and bacterial growth and destruction of interior decoration. Steam adversely affects the equipment used, the result is a reduction in the working process of the resource pool systems. 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 optimum moisture level is only possible when using these methods in combination.

Ventilation systems for pools
The main objective is to eliminate ventilationexcess moisture to pool room. It evaporates as with the pool surface, and with wet enclosures bodies people bathing. In this situation, aeration and ventilation basin is essential 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 the stage of designing the ventilation systemit should be noted that in order to reduce evaporation from the surface of the pool should be provided in the room temperature 2-3 degrees higher than the current water temperature. The relative humidity is best kept at the level of 55-60%.
In practice, two methods are used, with the aid of which the supply and exhaust ventilation of pools:
- Separate air supply system, exhaust ventilation, which function at the same time;
- The air handling system with heat recovery.
Separate inlet and exhaust ventilation
Separate system is characterized by a complexjob supply and exhaust ventilation systems. Application of this method differs cheaper cost of the equipment, but is characterized by a relatively high maintenance costs. To organize such a pool ventilation system requires a significant area for the installation.
This system provides freshoutside air and the simultaneous removal of moist air from the pool room. Ventilation equipment The device is held together with the construction works.
The exhaust system is represented by an exhaust fan built into the special exhaust channels.
Ventilation system consists of the following elements:
- The 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;
- The heater for the outside air that is used during the cold season;
- Paranasal fan for supplying air to the organization of the pool room;
- A control unit regulates the temperature and air volume.
An important point that requires attention inthe design of the ventilation system, it is the availability of automation systems. 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, ensure that the required air flow settings.
The air handling system with heat recovery
The air handling system with built-inheat recuperator functions in one unit. This method differs considerable expenditure on equipment purchase stage, but the operating costs are lower than for cheaper separate air handling system.
are indisputable advantages of its use:
- Save space in the room. Supply and exhaust system in a single unit, requiring less space to accommodate than the separate system. This point is important when choosing a ventilation system for a small pool.
- Energy savings. Using the built-in heat exchanger system achieves energy savings of up to 50-70% due to the fact that the supply air is performed by means of heating the exhaust air flow, but this does not occur when they are mixed. This feature allows you to reduce the built-in engine output by 2-2.5 times.
The main elements of this system include:
- Supply and exhaust fan;
- Purifying filter for outside air;
- Double valve that prevents the penetration of cold air when the unit is off;
- Heat Exchanger;
- A heater for heating the incoming air to a predetermined temperature for a heat exchanger located.
Uniform supply and exhaust system is equipped withautomatic temperature control and humidity, in addition, it may further be equipped with devices for the distribution of hot air to other rooms.
to use additional specialized equipment such as dehumidifiers for swimming pools to creating and maintaining an ideal climate.
Dehumidifiers for pools
The main purpose of dehumidifiers is borrowing indoor pool optimal humidity.
Using dehumidifiers for swimming pools Air cansignificantly 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 desiccant becomes the inability to remove unpleasant odors. This problem is easily solved with the help of shared ventilation.
A variety of modifications of the dryer allows you to select for the pool based on the specific use case. There are stationary and portable, floor and wall models.
The main parameters in selecting qualitydryer 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 principle of
Workflow dehumidifier based oncondensation principle, is located in the cluster of water vapor in the air on a special surface, characterized lower temperature. The mechanism of action is the same as that of the air conditioner, but the heat is not removed from the premises.
The principle of operation consists of the following devices: reacting air with a cooled surface carried condensation. Fan directs moist air from the pool room to the evaporator, where it is cool and condense moisture, which is then removed in a special container or through drainage. Further, air flows to the condenser, is heated to a predetermined temperature and falls back into the pool room. Work dryer is automatic.
Effectiveness of condensation dehumidifiers depends largely on the initial room temperature.
Dehumidification by adsorption
Work adsorption dryers isremoving moisture from the 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 room air treated pool.
These dehumidifiers for swimming pools differhigh efficiency and performance. The design of the adsorption rotor can simultaneously pass two parallel air flow. One thread guides treated and dry air into the room, and the additional flow of hot air removes moisture from the adsorbent. Continuous rotation of the rotor ensures a constant drainage of moist air and simultaneous regeneration of the adsorbent.
Dehumidifiers using assimilation principle,characterized by low productivity and efficiency, high energy costs. assimilation principle is that the heated air to intervene more water vapor than cold. This kind of dryers is practically not applicable for drying basins, since their operation depends largely on the ambient temperature. The assimilation dryers do not provide effective results in a high relative humidity environments.
When choosing a dehumidifier is necessary to pay attentionthe vibration and noise during operation. These parameters have an important influence on the comfort of the people present in the pool, as the equipment is designed for continuous operation without a shutdown.
With proper organization of the pool ventilation anddehumidification creates a comfortable environment for the people present, increases operating life of the building as a whole. Using the full range of activities allows for the necessary fresh air and avoid high humidity. Creating a favorable climate in the swimming pool is possible only when the perfect balance between the air temperature and humidity.
