Desription:
compressor is a driven fluid machine that lifts low-pressure gas to high-pressure gas and is the heart of a refrigeration system. It inhales low-temperature and low-pressure refrigerant gas from the suction tube, and drives the piston to compress it through the motor operation, and discharge the high-temperature and high-pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle.
Thus, the refrigeration cycle of compression → condensation (heat release) → expansion → evaporation (heat absorption) is realized. Compressor is divided into piston compressor, screw compressor, centrifugal compressor, linear compressor and so on. The entry introduces the working principle, classification, accessories, specifications, operation requirements, compressor production, common faults and environmental requirements, selection principles, installation conditions and development trends.
Compressors can be divided into volumetric compressors and velocity compressors according to their principle. Volumetric type is divided into: reciprocating compressor, rotary compressor; Speed compressors are divided into: axial compressors, centrifugal compressors and mixed flow compressors.
Today's home refrigerator and air conditioner compressors are volumetric, which can be divided into reciprocating and rotating. Reciprocating compressors use piston, crank, connecting rod mechanism or piston, crank, slide tube mechanism, rotary type is mostly used rolling rotor compressor. In commercial air conditioners, more are centrifugal, scroll, screw.
According to the application range, it can be divided into low back pressure type, middle back pressure type and high back pressure type. Low back pressure type (evaporation temperature -35 ~ -15 ºC), generally used in household refrigerators, food freezers, etc. Medium back pressure type (evaporation temperature -20 ~ 0 ºC), generally used in cold drink cabinets, milk coolers, etc. High back pressure type (evaporation temperature -5 ~ 15 ºC), generally used in room air conditioners, dehumidifiers, heat pumps, etc.
