How Does the Wine Cabinet Cooling Unit Work?

How does the wine cabinet cooling unit work:
1.Working conditions: This unit is suitable for the space with the return air system and is not suitable for the new air system. The normal working conditions are 5 ° C ~ 43 ° C.

2.Refrigeration principle: The high-pressure liquid refrigerant flows out through the filter, and is throttled and depressurized by the expansion valve to enter the evaporator. Due to the reduced pressure, the refrigerant continuously absorbs heat transferred from the air to the evaporator in the evaporator and evaporates into steam. The steam is then sucked in by the compressor, and the compressed high temperature and high pressure gas enters the air-cooled condenser. The heat is taken away by the heat sink of the condenser. The refrigerant becomes a high temperature and high pressure liquid, and then passes through the filter to the expansion valve. This cycle continues to remove heat from the room and reduce the room temperature.
3. Heating principle: When the temperature of the conditioned air is lower than the required temperature, the computer controller of the constant temperature and humidity machine turns on the electric heater, heats the air, and sends it to the room to be heated to achieve the purpose of heating.

4. Dehumidification principle: When the humidity in the conditioned air is greater than the required value, the air is cooled to below the dew point temperature through the evaporator, and the moisture in the air is precipitated to achieve the purpose of dehumidification.

5. Humidification principle: When the relative humidity of the conditioned air is lower than the required value, the computer controller of the constant temperature and humidity machine turns on the electrode humidifier to make the electrode humidifier work. The water is heated and boiled into steam, which is sent to the air-conditioned room through a fan to achieve the purpose of humidification.
