Types of chiller compressor In the current application of the refrigeration industry, the efficiency of the equipment is closely related to the temperature. Under precise temperature control, the efficiency of the refrigeration equipment is required to be improved to a certain extent. Different situations are crucial to the selection of compressors, so let's take a look at the practical application of different compressors! Types of chiller compressor: Screw chiller compressors are all positive displacement refrigeration compressors, which can be divided into reciprocating compressors and rotary compressors. The reciprocating compressor uses a piston, crank, connecting rod mechanism or piston, crank, slide tube mechanism, and the rotary compressor uses a rotating shaft crank mechanism. According to the scope of application, it can be divided into low temperature, medium and low temperature, and ultra low temperature compressors.
Low-temperature compressor (evaporating temperature -35～-15℃), generally used in food freezers, etc. Medium and low temperature compressors (evaporating temperature -20～0℃), generally used in refrigerators, etc. Ultra-low temperature compressor (evaporation temperature -5 ~ 15 ℃), generally used in dehumidifiers, heat pumps, etc. The practical application of the chiller compressor: Piston compressors have the oldest qualifications and are used in many equipment such as cold storage. Rotary compressors are also mainly used in refrigeration devices. Scroll compressors are mainly used in low-temperature equipment and refrigeration units. Screw compressors are mainly used for large cooling capacity, and are used in cold storage and chiller units. Centrifugal compressors have greater cooling capacity. Generally used in chillers.
