Screw compressors are often used in connection with cooling systems. A screw compressor draws in coolant fumes continually, while some other compressor types draw in portions.
In a screw compressor, the compressor and motor are separated, and therefore connected with an axle or V-belt. As the compressor and motor are separated, the compressor can be used with ammonia as the coolant.
The cooling output of cooling systems can be regulated by adjusting compressor performance. A screw compressor is well-suited for regulation of cooling systems, as it features smooth adjustment from 100 % to almost 0%.
