Compressor is a low-temperature, low-pressure vapor or gas compression into high-temperature, high-pressure vapor or gas, thereby increasing its temperature and pressure, for the refrigeration system to provide refrigeration energy for the core components.
Refrigeration machine, on the other hand, refers to the refrigeration compressor, condenser, expansion valve and evaporator and other components assembled together to form the entire refrigeration unit.
Second, the difference between the compressor and refrigerator
1. Definition is different: the compressor is the low-temperature, low-pressure vapors or gases compressed into a high-temperature, high-pressure vapors or gases of the core components, while the refrigeration machine refers to the entire refrigeration unit.
2. Different roles: the compressor is the core component of the refrigeration cycle system, which can provide high-temperature and high-pressure refrigerant required for the refrigeration cycle, while the refrigeration machine refers to the entire refrigeration unit, including the compressor, condenser, expansion valve and evaporator and other components of the refrigeration system.
3. Composition is different: the compressor is a component of the refrigeration machine, while the refrigeration machine consists of a number of components, including the compressor, condenser, expansion valve and evaporator and other components.
4. The use of different scenes: compressors are widely used in industrial, agricultural, medical and other areas of refrigeration and air-conditioning equipment, while the chiller is not only used in refrigeration and air-conditioning equipment, but also widely used in cold storage, seafood preservation and other occasions.
5. Energy utilization is different: compressors can use electricity as energy, but also gas, diesel, etc. as energy, while the chiller generally use electricity as energy.
Overall, the compressor is a component of the refrigeration machine, is the core component of the refrigeration cycle system, while the refrigeration machine is composed of a number of components of the entire refrigeration device.
