[0002] In the refrigeration industry, there are two types of chillers: air-cooled chillers and water-cooled chillers. According to the compressor, they are divided into screw chillers, scroll chillers, and centrifugal chillers. In terms of temperature control, they are divided into low-temperature industrial chillers and normal temperature chillers. The temperature of normal temperature units is generally controlled within the range of 0 degrees to 35 degrees, and the temperature of low-temperature units is generally controlled within the range of 0 degrees to -100 degrees.

[0003] Air-cooled chillers are one type of chillers. They cool water at room temperature to a certain temperature through the chiller's compressor to enhance the cooling of molds or machines.
