This chapter focuses on the types of screw chiller ! According to the air-conditioning function, different refrigerants, condensation methods, the seal structure of the compressor, the structure of the evaporator, and screw refrigeration compressors, there are six different classifications. Information!
1. Divided into single cooling type and heat pump type according to air conditioning function.
2. According to the refrigerant used, it is divided into R134a and R22.
3. According to its condensation method, it is divided into water-cooled screw chiller and air-cooled screw chiller!
4. According to the seal structure of the compressor, it is divided into open type, semi-closed type and fully closed type.
5. Divided into ordinary type and full liquid type according to the structure of the evaporator
6. Classified according to different screw refrigeration compressors used in screw chiller. Screw refrigeration compressors are divided into two types: twin screw and single screw. The twin-screw refrigeration compressor has a pair of rotors with helical teeth that are coupled to each other and rotate in opposite directions. The single screw refrigeration compressor has a rotor screw with six spiral grooves machined on the outer cylindrical surface. On the left and right sides of the butterfly and lever, the identical planetary gears with 11 racks are installed vertically!
A detailed understanding of the classification of screw chiller is undoubtedly a great help for friends who need to purchase screw chiller!
