The refrigeration compressor is the core component in the refrigeration system, responsible for compressing low-temperature and low-pressure refrigerant gas into high-temperature and high-pressure gas, thereby achieving the refrigeration cycle.
Common types of refrigeration compressors include rolling rotor compressors, scroll compressors, semi enclosed piston compressors, screw compressors, and centrifugal compressors.
Characteristics and application scenarios of different types of refrigeration compressors
Rolling rotor compressor: mainly used for small air conditioners below 3HP, with a simple structure, suitable for small refrigeration equipment.
Vortex compressor: widely used in air conditioning units above 3HP, with the characteristics of high efficiency and low noise
Semi closed piston compressor: suitable for refrigeration equipment such as cold storage and display cabinets, with a simple structure and mature manufacturing technology, suitable for a wide range of pressure ranges and refrigeration capacity requirements
Screw compressor: simple structure, few parts, suitable for high-efficiency refrigeration needs, widely used in various working conditions
Centrifugal compressor: compresses gas in refrigeration systems, suitable for a wide range of operating conditions and high efficiency refrigeration needs
