Screw compressor is composed of a pair of parallel, meshing each other's Yin and Yang screw, which is widely used in medium and large refrigeration systems. Screw compression is divided into single screw and twin screw two, usually said screw compressor refers to the twin screw compressor.

Screw compressor has the following characteristics:

1. Screw refrigeration compressor has simple structure, small number of parts, no wearing parts like valve, piston ring, rotor, bearing, etc., strength and wear resistance are relatively high.

2, screw compressor has the characteristics of forced gas transmission, that is, the exhaust volume is almost not affected by the exhaust pressure, there is no surge phenomenon in the small exhaust volume, and it can still maintain a high efficiency in a wide range of working conditions.

3, screw compressor is not very sensitive to liquid stroke, you can use oil injection cooling, so under the same pressure ratio, the exhaust temperature is much lower than the piston type, so the single-stage pressure ratio is high.

4, the use of slide valve adjustment, can achieve stepless energy regulation. Cooling capacity.
