The chiller unit has the advantages of large refrigeration capacity, precise temperature control, stable and reliable operation, and is an indispensable and important equipment in many industrial and commercial fields. With the continuous development of technology, chillers are also constantly being upgraded and improved to meet more diverse needs and higher energy efficiency standards.

The chiller unit can also be classified based on factors such as the type of compressor, type of refrigerant, refrigeration capacity, and control method. For example, according to the type of compressor, chillers can be divided into piston type, screw type, centrifugal type, etc; According to the type of refrigerant, it can be divided into ammonia refrigeration units, Freon refrigeration units, etc.
