With the improvement of people's living standards, the use of dehumidifiers is becoming more and more popular, especially ceiling dehumidifiers, which are very popular with consumers. Ceiling dehumidifiers are especially popular among consumers. Ceiling dehumidifier is a kind of refrigerated dehumidifier, usually moist air is sucked into the machine from a fan, and the evaporator is cooled to below the dew point through a refrigeration compressor. The moist air is condensed into water through the surface of the evaporator, collected in the water basin, and then flows into the water tank. The dry air is reheated in the condenser and discharged from the air outlet, so that the humidity in the room is continuously reduced. The working principle of the ceiling dehumidifier is as follows:

1. Defrosting process: When used in a relatively low temperature environment, it will cause the heat exchange system of the ceiling dehumidifier to freeze. Since this process cannot be avoided, the ceiling dehumidifier enters the dehumidifier regularly when the ambient temperature is low. Frozen state. At this time, the ceiling dehumidifier stops the compressor first, uses the heating wire of the evaporator to heat the heat exchange plate, and then uses the fan power to produce the defrosting effect. During defrosting, the ceiling dehumidifier cannot dehumidify the air. Therefore, for low-temperature environments, the dehumidification effect of conventional refrigeration dryers is not ideal. It is recommended to buy a rotary dryer.

2. Effect on room temperature: After the air passes through the evaporator, the moisture in the air condenses on the evaporator, causing the temperature to drop. The temperature of the air passing through the secondary heat recovery device will rise, while the temperature of the leaving air will not drop. The temperature of the air dryer and spray gun will rise slightly.

The above two points are all about the working principle of the ceiling dehumidifier, thank you for your understanding and support!
