If partial pressure of water vapor contained in the ambient air is lower than the

saturation pressure, evaporation occurs over the pool water’s surface. It is

possible to see the evaporation in large amount of water at indoor swimming

pools. Thus, the amount of moisture in the air rises to inappropriate level.

Depending on the high level of moisture in the building, sweating occurs at

windows and walls thus it results formation of corrosion and fungus in

structure components. Besides damaged of structural components in the

building, it lowers the blood circulation in people and results lower capacity in

sportive activities. According to VDI 2089/1, the humidity in indoor swimming

pools is ranked between 40 -64 %.

As a conclusion removing these adverse effects can be made by keeping the

humidity values appropriate by the humidifier.

The advantages of FourSeason Four-Pool series Swimming pool Humidifier

equipment:

• Absolute humidity control

• The necessary amount of fresh air

• Air flow control

• Mechanical cooling

The features such as the comfort and energy saving are kept at the highest

level in all operating process.

46% of energy saving is spent for heating and ventilation at indoor swimming

pools.

In scope of these applications, very suitable temperatures are revealed for heat

recovery. By virtue of using the heat pomp and recycling device during the

dehumidification process in ventilation, the value of heat recovery i.e.

coefficient of performance (COP value) in return air of swimming pool is

between 4 and 5.

1.1. Working Principle

FourSeason Four-Pool series Pool Dehumidifier is manufactured with fullautomatic control system with micro-processor. Thus, all components on equipment are able to be controlled to guarantee the result.As an example, while the device is idle and working without dehumidification function, it provides air circulation inside of the pool. When humidity sensor exceeds the setting value, it passes to dehumidification mode. While it is working at idle position, fresh air and exhaust dampers are turned off since there is nobody in the pool so no need to have fresh air. Heat pump comes into operation and it starts dehumidification process. Using by-pass dampers, it is mixed with dehumidified air by cooling with return air. This process continues until actual humidity value reaches to set value of humidity sensor..In active use, fresh air and exhaust dampers open. By pass damper 14 is turned off.

Scenario 1: WINTER- NIGHT

It is ideally preferred at nights during the winter months. Since there is no user in the pool, the fresh air and exhaust dampers are closed.. The mixture dampers are completely turned on. It runs with internal air by 100%. The compressor comes in and it fulfils the task of dehumidifying. The humidly rate of cooled air for dehumidifying is kept at fixed value thus increased temperature while passing over the condenser.

Scenario 2: WINTER- DAY

It is ideally preferred during the active pool hours in winter months when the outside temperature is low. The suction air leaves a part of heat while passing over the heating pipe. The compressor comes in and it fulfils the task of dehumidifying for energy saving, a certain amount of exhaust air is mixed with fresh air. Heat that is accumulated in heating pipe is rolled back. Heater battery brings the blowing temperature which has been lowered after dehumidifying process, to comfort value.

Scenario 3: SUMMER

It is ideally preferred in cases when the outside temperature is higher than the inside temperature of the pool. In such cases, the heating pipe and heating pumps are disabled. The humidity is kept constant by 100% fresh air. The compressor does not start in.
