In indoor swimming pool halls, the air can quickly become saturated with humidity and condensation. This is why the dehumidifier is essential equipment to maintain a humidity level which keeps the room healthy, preserves the health of bathers and ensures the sustainability of the building. But how does the swimming pool dehumidifier work?
As moist air from the pool room is drawn in by the dehumidifier fan, the circuit it takes is immutable and repeats itself until the chosen humidity level set point is reached. The stale air is therefore sucked in by the fan and transported to the refrigerated evaporator. This has the effect of further cooling the air, bringing it below the dew point, while increasing the relative humidity. The micro-droplets contained in the air condense on the cold surface of the evaporator, the water trickles into a tray or is directed to the house's wastewater network. The air is now free of humidity and continues the circuit on its own. It will pass into the condenser which heats it. The heated, dry air is returned to the room.
In the compressor, the gas circulates at low pressure and is hot. It is directed towards the capacitor. During this time, the fan draws in water vapor laden air from the room and forces it into the condenser. When the hot refrigerant gas meets the cold humid air, a heat exchange occurs.The gas which has transmitted its heat to the air, becomes liquid as it cools, it is temporarily stored in a bottle. Then the refrigerant under high pressure passes through the dryer which is responsible for removing excessive humidity from the air. The fluid continues its course and passes through a capillary tube or a thermostatic expansion valve. Both are intended to reduce pressure and control the flow of refrigerant through the evaporator. The refrigerant reaches its boiling point and reverts to low-pressure gaseous form. The loop is closed, the cycle begins again, compressor, capacitor...
Currently, the latest “generation” refrigerant R32 circulates in the dehumidifier. More environmentally friendly, less polluting, it is used in smaller quantities. It is its changes of state, gaseous, liquid, low then high pressure… which make it possible to eliminate humidity and heat the air. But the gas alone is not enough, it needs other organs to circulate and perform its role.The electronic card is another essential element for the operation of the device. It makes it possible to coordinate the correct operating order of the different elements. The more advanced the card, the greater the performance of the device.The electric dehumidifier for indoor swimming pools has the same operating principle as the swimming pool heat pump. But, instead of heating the water, it dries the air and warms it.
Knowing what an indoor pool dehumidifier is will help you understand why installing a pool dehumidifier in the indoor pool room is essential. Knowing some features of the dehumidifier will help you better understand this device and when should you install a pool dehumidifier. Knowing everything about the operating principle of the swimming pool dehumidifier will help you choose the device best suited to your indoor swimming pool.
