English
A water-cooled screw chiller is a type of cooling system that uses water as the cooling medium and a screw compressor to compress refrigerant. The refrigerant absorbs heat from a device and releases it to a cooling tower, providing cooling to the building or process.
The screw compressor is an efficient and reliable type of compressor that can handle a wide range of cooling loads. It operates at a low speed, which reduces wear and tear on the compressor and makes it quieter than other types of compressors. The compressor has two interlocking screws that rotate, drawing in refrigerant and compressing it.
