Actual cases In the device, the refrigeration compressor is the main equipment to realize the refrigeration cycle, which can carry out the continuous process of refrigerant gas from low pressure to high pressure. The compressor can be divided into refrigeration compressor, air conditioning compressor and air conditioning compressor. According to the speed of the compressor can be divided into fixed speed compressor and frequency conversion control compressor. According to the work used, can be divided into ammonia compressor, freon compressor and so on. The structure is divided into open, semi-closed and fully enclosed compressor. According to the working principle of compressor, it can be divided into two types: volume type and speed type. Volume type compressor is done through variable working volume of the gas compression and transportation process, it can be divided into two kinds of piston and rotary, piston (also known as the reciprocating compressor is the piston within the cylinder for reciprocating motion, called reciprocating piston; Rotary compressors are the rotating motions of the rotor in the cylinder. It mainly has rolling rotor type compressor, vortex type compressor and so on. The speed type compressor increases the speed of the gas in the rotating impeller and then converts the kinetic energy of the gas to the pressure energy through the guide, thus completing the gas compression and delivery process. The commonly used is centrifugal compressor. The structure and working principle of compressor Unit: dalian sanyo, dajin, Hitachi, guangdong meizhi, matsushita, ruizhi, zhuhai lingda, Toshiba, e
