Introduce the working principle of industrial dehumidifier

The defrosting principle of the refrigerated dehumidifier:
When using a compressor-type dehumidifier in a relatively low temperature environment (generally below 10 degrees Celsius), it will cause frosting on the heat exchange system of the dehumidifier, and this process is inevitable, so the compressor-type dehumidifier should be kept at ambient temperature. When it is low, it will enter the defrosting state periodically.
At this time, the dehumidifier will first stop the compressor, and use the evaporator heating wire (a part of the heat exchange system) to heat the temperature of the heat exchange plate, and then output it through the fan to produce a defrosting effect.
This time-consuming needs to be determined by the ambient temperature. The lower the ambient temperature, the longer the time-consuming. During the defrosting process, the compressor-type dehumidifier cannot perform dehumidification work. The effect is not ideal. If it is a dehumidification environment with low ambient temperature, you can buy a new type of rotary dehumidifier.
The working principle of the rotary dehumidifier:
1. The manufacture of the dehumidification rotor is made of ceramic fiber paper with a temperature resistance above 500°C, which is formed into a honeycomb rotor through a molding machine, and then coated with silica gel between the ceramic fibers, so the dehumidification rotor will not burn and burn. Deliquescence and other issues. Since its dehumidification function is physical rather than chemical, it does not produce any harmful chemicals.
2. The dehumidification principle of the rotary dehumidifier is to use the silica gel coated on the rotor to physically absorb the moisture in the air on the porous synthetic silica gel, and then in the regeneration area of the rotor, the moisture adsorbed on the silica gel The water vapor in the hole is heated and vaporized, and reaches the inlet of the AC heat exchanger to form high-temperature and high-humidity air, and then passes through the heat exchanger that has been cooled by the indoor cold and humid air, and the condensed water is discharged due to the difference in dew point.
