Air Conditioning Systems Introduction - Coggle Diagram

- - - - A compressor compresses the low-temperature and low-pressure saturated or superheated gas into a high-temperature and high-pressure superheated gas, for outdoor heat exchanging purposes
    - - After a throttle, the high-temperature,high-pressure liquid releases pressure. As a result, the refrigerant vaporizes. The high-temperature,high-pressure liquid also absorbs much heat to reduce the temperature of the liquid refrigerant. As a result, a low-temperature and low-pressure substance in both gas and liquid forms is formed.

    - - The high-temperature and high-pressure superheated gas is condensed into a high-temperature and high-pressure saturated or supercooled liquid in a condenser
    - - A refrigerant vaporizes in an evaporator and becomes a low-temperature and low-pressure saturated or superheated gas, and then absorbs heat from indoor air.
- - - - small and medium-sized data centers without 24 h chilled water source (with the cooling capacity less than 500 kW)
    - - areas with abundant water sources;
    - - large and medium data centers
    - - large and medium data centers
- - - - The medium that exchanges heat and humidity with air is in direct contact with air > water chambers and humidifiers
    - - The medium that exchanges heat and humidity with air is not in direct contact with air. > surface coolers , air heaters , evaporators and condensers
    - - Electrode Humidifier
      - Infrared Humidifier
    - - Refrigeration Dehumidifier
      - Rotary Dehumidifier
- - - - Supplying and returning air both from the top of room (up supply and up and up return ).
      - Supplying air from the middle of side walls of room (central supply).
      - Supplying air from the top of room (up supply) and returning air from the bottom of room (down return)
