Air-cooled Chillers丨Refrigerated Circulators


       Air cooled chillers use shell and tube evaporators to exchange heat between water and    refrigerant. The refrigerant system absorbs the heat in the water. After cooling the water,    the heat is brought to the condenser through the compressor, and then dissipated to the    outside air by the cooling fan.

      Characteristics of air-cooled chillers:

  1. The air-cooled chiller does not need to be connected to a cooling tower, and is suitable for environments with poor impurities. (Impurities are easily mixed in the cold water tower, and the dust will cause the cooling water circulation circuit to be blocked, resulting in a decrease in cooling capacity).
  2. Air-cooled chillers are most suitable for areas with poor water quality, which can save other accessories such as cold water towers.
  3. The use of large-capacity condenser makes it easier and more convenient to operate.
  4. The floor space is reduced to a greater extent, and the installation is very convenient.
  5. The air-cooled chiller adopts the design of the upper air outlet.

Working Principle

       Using a single compressor, through the method of natural separation and multi-stage overlapping, the overlapping between the high boiling point components and the low boiling point components is achieved, and the purpose of preparing low temperature is achieved;

       Use ethylene glycol mixed with water mixture for circulating refrigeration, strict circulating pipeline design to prevent circulating water pollution and prolong the use time of circulating water;

       Fully enclosed design, no water absorption during low temperature operation, to ensure the purity of the cold heat transfer medium, prevent ice crystals, and improve the life of the heat transfer fluid;

       The temperature difference between the compressor on and off can be set; the ambient temperature monitoring function prevents the system from operating ambient temperature too high.
