The Characteristics of Screw Refrigeration Compressor

Screw refrigeration compressor has the following advantages:

1. Screw refrigeration compressor only rotational motion, no reciprocating motion, so the balance is good, vibration is small, can improve the speed of refrigeration compressor.

2. Screw refrigeration compressor structure is simple, compact, light weight, no suction and discharge valve, less wear parts, high reliability, long maintenance cycle.

3. Screw type refrigeration compressor without clearance, no suction and discharge valve, so in the low evaporating temperature or high compression ratio conditions still have high volumetric efficiency; In addition, due to the cylinder oil spray cooling, so the exhaust temperature is lower.

4. Screw-type refrigeration compressor is not sensitive to wet compression.

5. Screw-type refrigeration compressor can achieve stepless adjustment of the refrigeration capacity.

Screw refrigeration compressor has the following disadvantages:

1. Screw-type refrigeration compressor operation noise.

2. Screw-type refrigeration compressor energy consumption is large.

3. Screw-type refrigeration compressor needs to spray oil in the cylinder, so the lubricating oil system is more complex, the unit volume Large.
