portable air purifier.Do you know the working principle of a constant temperature and humidity machine

　　The unit adopts the principle of refrigeration compression dehumidification. Firstly, the compressor compresses the refrigerant and uses an evaporator for cooling. As the temperature drops below the dew point of the air, the water vapor contained in it will be condensed and discharged from the lower collection tray of the evaporator. This continuous circulation gradually reduces the indoor humidity.

　　Equipment operating principle:

　　① Refrigeration principle: When the temperature and humidity sensor of the machine detects that the room temperature is 2 degrees higher than the set temperature, the host controller sends a signal to the outdoor unit. The outdoor unit is transformed into a condenser, and the indoor unit is transformed into an evaporator to cool the indoor refrigeration. It is then sent to the air-conditioned room through a fan to achieve the purpose of cooling.

　　② Heating principle: When the temperature and humidity sensor of the machine detects that the room temperature is 2 degrees lower than the set temperature, the host controller sends a signal to the outdoor unit. The outdoor unit is transformed into an evaporator, and the indoor unit is transformed into a condenser to provide indoor heating. If the heating capacity is insufficient, the auxiliary electric heater will be connected to heat the air, and it will be sent to the air-conditioned room through a fan to achieve the purpose of heating.

　　③ Dehumidification principle: When the temperature and humidity sensor of the machine detects that the room humidity is 5% higher than the set humidity, the host controller sends a signal to the outdoor unit, the outdoor unit compressor starts, and the indoor unit transformer evaporator cools and dehumidifies, quickly dehumidifying without changing the indoor temperature. When the indoor temperature is higher than the set temperature, the outdoor unit transformer condenser and indoor unit transformer evaporator are used to cool and dehumidify the indoor air, and are sent to the air-conditioned room through fans to achieve the purpose of dehumidification.

　　④ Humidification principle: When the temperature and humidity sensor of the machine detects that the room humidity is 5% lower than the set humidity, the host controller sends a signal to the humidifier to work, and it is sent to the air-conditioned room through the fan to achieve the purpose of humidification.
