In the refrigeration industry, it is divided into two types: air-cooled chillers and water-cooled chillers. According to the compressor, it is divided into screw chillers, scroll chillers, centrifugal chillers. In terms of temperature control, it is 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. Low temperature unit temperature control is generally around 0 degrees to -100 degrees.
Chillers are also known as: chillers, refrigeration units, ice chillers, cooling equipment, etc. Because of the wide range of uses in various industries, the requirements for chillers are also different. Its working principle is a multifunctional machine that removes liquid vapor through compression or heat absorption refrigeration cycles.
