Description

Technical Field

[0002] The low-temperature screw unit, also known as the ultra-low-temperature screw refrigerator, is a chiller refrigeration device. Its main feature is the use of a spiral rotor compressor and Freon or other low-temperature environmentally friendly refrigerants as refrigerants. The main components of the low-temperature screw unit include the shell part and the rotor part. The advantage of this unit lies in its powerful refrigeration capacity, which can provide a stable refrigeration effect at a lower temperature. At the same time, the design of the spiral rotor compressor makes the unit more stable during operation and has lower maintenance costs. In addition, the low-temperature screw unit also has a high energy efficiency ratio, which can effectively reduce operating costs. The low-temperature screw unit is an efficient and stable chiller refrigeration device, suitable for various scenarios requiring low-temperature refrigeration.
