Compressor  is to enhance the low pressure gas to a high pressure gas driven fluid machinery, is the heart of the refrigeration system. It from the suction pipe at low temperature and low pressure refrigerant gas inhalation, through the rotation of the motor drives the piston to compress them, to the exhaust pipe of high temperature and high pressure refrigerant gas discharged, to provide power for the refrigeration cycle, in order to achieve compression, condensation (exothermic), expansion and evaporation (heat absorption) refrigeration cycles.

Compressor, piston compressor, screw compressor, centrifugal compressor, linear compressor, etc.. Piston compressor is composed of a casing body, a motor, a cylinder body, a piston, a control device (starter and thermal protection device and cooling system. Cooling methods are oil cooling and air cooling, three kinds of natural cooling. Straight line compressor without shaft, no cylinder, sealing and heat dissipation structure.

The compressor specification is divided according to the input power. Each specification is about 50W. In addition, there are divided according to the cylinder volume
