Machine Room Air Cooled Precision Air Conditioning is mainly composed of compressor, condenser, expansion valve and evaporator.
Generally speaking, the refrigeration process of the air conditioner is: the compressor will be compressed into high pressure gas after the evaporator absorbs the heat, and then sent to the condenser of the outdoor machine; The condenser will release the heat energy of the high temperature and high pressure gas to the surrounding air through the fan, so that the high temperature and high pressure gas refrigerant will be condensed into liquid again, and then sent to the expansion valve; The expansion valve will cool the liquid refrigerant brought by the condenser pipeline into a liquid and gas mixed refrigerant, and then sent to the evaporator loop; The evaporator evaporates the refrigerant in the mixed state of liquid and gas into gaseous refrigerant by absorbing the heat in the room environment, and then sends it back to the compressor, repeating the previous process.
The importance of temperature and humidity control to computer room
The equipment in the computer room is composed of a large number of micro-electronics, precision mechanical equipment and so on, and these equipment uses a large number of electronic components, mechanical components and materials which are easily affected by temperature and humidity.
