Working principle of swimming pool dehumidifier

What is the working principle of swimming pool dehumidifier?

In an indoor swimming pool, a swimming pool shelter or a spa room, it is not uncommon to see condensation taking up considerable space. The humidity level prevailing in these spaces must be controlled if we want to enjoy this aquatic area peacefully for many years. To combat this natural phenomenon, the dehumidifier is the ideal device and perfectly simple to use. But how does the swimming pool dehumidifier work?

The electric dehumidifier for swimming pools: how does it work?

What are the conditions for comfortable swimming in the indoor swimming pool?

For the health of the room to last for many years, and for daily swimming to be pleasant and always a pleasure, it is necessary to tend and control the 3 conditions which promote condensation. Pool water between 25 and 30°C, ideally an ambient air temperature which must be 1°C below and maintain a hydrometry rate between 60 and 70%. If the swimming pool heat pump regulates the water temperature, adequate efficient heating heats the ambient air, you need a dehumidifier to overcome the humidity in the air.

What happens in a swimming pool dehumidifier in operation?

The operating principle of the dehumidifier for swimming pools is almost the same as the heat pump or the refrigerator.

The hot air from the room is sucked in by the fan integrated into the device.

The refrigerant which is at low pressure and low temperature cools the cold surface of the evaporator (metal grilles). When humid air is blown and comes into contact with the cold evaporator, the air temperature drops while the humidity increases. Then, when the dew point is reached, the humidity in the form of water vapor condenses, becomes liquid and runs off into the tank, the tank or it is evacuated towards the wastewater of the home.

During this action the air has cooled and is colder than when it entered the dehumidifier, the goal is now to warm it up. This is the role of the condenser supported by the compressor.

The compressor, as its name suggests, compresses the fluid into gas form at high pressure. By this action, the gas heats up and rises in temperature.

The condenser is a jar crossed by a coil which transports the hot gas at high pressure. The cooled but drier air circulates through the jar and heats up through the coil. The temperature of the air and gas changes, one heats up while the other cools.

The dry, hot air is reinjected into the room, the ambient temperature then increases between 2 and 5°C.

During this time, the fluid in the gaseous state when it enters the condenser leaves in the liquid state under high pressure.

The fluid will then pass in the regulator. The sudden shock causes a significant drop in pressure and the temperature of the refrigerant drops to a negative temperature.

The circle is complete. The dehumidifier cycle resumes and continues until the set point programmed and defined on the humidistat is reached.

Knowing what a dehumidifier for indoor swimming pool is will allow you to understand why installing a swimming pool dehumidifier in the indoor swimming pool room is essential. Knowing the technical elements of the dehumidifier as well as some of the characteristics of the dehumidifier will help you better understand this device and when should you install a swimming pool dehumidifier. You therefore have all the cards in hand to choose the device best suited to your indoor swimming pool.
