How to improve the service life of screw chillers and reduce the failure rate of screw chillers? This problem has been plaguing many friends, and it is also the relevant knowledge module that they really want to know. To solve this problem, we must have a comprehensive understanding of the screw chiller. Only master the knowledge of the mechanical equipment and understand its performance. .
Screw chiller classification
This chapter focuses on the types of screw chillers! According to the air conditioning function, the difference of the refrigerant, the condensation mode, the sealing structure of the compressor, the structure of the evaporator, and the screw refrigeration compressor, a total of six different points can be made.
Class, the following is a detailed list of the information of these six categories for everyone!
1. According to the air conditioning function, it is divided into single cooling type and heat pump type.
2. According to the different refrigerants, it is divided into R134a and R22.
3. According to its condensation mode, it is divided into water-cooled screw chiller and air-cooled screw chiller!
4. According to the sealing structure of the compressor, it is divided into open type, semi-closed type and fully enclosed type.
5. Divided into normal type and full liquid type according to the structure of the evaporator
6. Classification according to the different types of screw refrigeration compressors used in screw chillers. Screw refrigeration compressors are divided into two types: twin screw and single screw. The twin-screw refrigeration compressor has a pair of rotors that are twisted and twisted in opposite directions. The single-screw refrigeration compressor has a rotor screw with six spiral grooves on the outer cylindrical surface.
