Defrost principle of frozen type dehumidifier
In the low temperature environment, generally below 10 degrees celsius, if using the compressor type dehumidifier, the dehumidifier heat exchange system will be frost.
Therefore, when the temperature is low, the compressor dehumidifier will enter the defrost state regularly. The dehumidifier will stop the compressor work first, and use the evaporator heating wire to heat the heat exchange plate, and then through the fan output to produce the defrosting effect.
This time is determined by the ambient temperature, the lower the ambient temperature, the longer the time.
In the defrosting process, the compressor dehumidifier cannot perform dehumidification. Therefore, the temperature is low, the dehumidification effect is not ideal. If in the low temperature environment, can choose the wheel type dehumidifier.
Working principle of wheel dehumidifier
1. how does the desiccant wheel do? With the ceramic fiber paper with temperature of over 500 ℃, the runner wheel is formed by the forming mechanism, and then the silica gel is coated between the ceramic fiber.
In this way, the desiccant wheel does not occur burning and Hygroscopy.
Because its function of dehumidification is to take advantage of physical, not chemical, it does not produce harmful chemical substances.
