This article mainly focuses on the types of screw chillers. According to the air conditioning function, the different refrigerants, the condensing method, the structure of the compressor's seal structure, the structure of the evaporator, and the screw-type refrigeration compressor, six different classifications can be made. The following is a detailed list of the six categories. Information!
1. According to the air conditioning function, it is divided into single cold type and heat pump type.
2. According to the use of refrigerants are divided into two different R134a and R22.
3. According to its condensing mode, it is divided into water-cooled screw chiller and air-cooled screw chiller!
4. According to the seal structure of the compressor is divided into open, semi-closed and fully enclosed.
5 according to the structure of the evaporator is divided into ordinary and full liquid type.
6. According to different types of screw refrigeration compressors used in screw chillers. Screw refrigeration compressors are classified into twin-screw and single-screw. A twin-screw refrigeration compressor has a pair of helical gear rotors that are twisted together and rotated in opposite directions. The single-screw refrigeration compressor has a rotor screw machined with six spiral grooves on the outer cylindrical surface. Vertically mounted on the left and right sides of the butterfly and pole are the same planetary gears with 11 racks!
A detailed understanding of the classification of screw chillers is undoubtedly of great help to a friend who needs to purchase a screw chiller!
