Compression chiller: through the compression of refrigerant to achieve refrigeration, is the most widely used kind of chiller. According to the type of compressor can be divided into piston compressor, screw compressor and centrifugal compressor and so on.
Absorption chiller: through the absorption and release of the absorber to achieve refrigeration, mainly divided into single-stage absorption and double-effect absorption of two kinds.
Magnetic levitation centrifugal chiller: refrigeration is realized through the magnetic levitation centrifugal compressor, which has the advantages of high efficiency and energy saving, low noise and so on.
Condensing chiller: cooling is realized through the release of heat from the refrigerant in the condenser. According to the condensing method can be divided into water-cooled and air-cooled.
Air-source heat pump chiller: cooling and heating are realized through air-source heat pump technology, which has the advantages of high efficiency, energy saving and environmental protection.
The above are common types of chiller units, different types of chiller units in the refrigeration principle, scope of application, performance parameters and other aspects of the difference.
