Description:
The refrigeration compressor is the core and heart of the refrigeration system. The capacity and characteristics of the compressor determines the capacity and characteristics of the refrigeration system. In a sense, the design and matching of refrigeration systems reflect the capabilities of the compressor. Therefore, the refrigeration industry in all countries in the world has invested a lot of energy in the research of refrigeration compressors, and new research directions and research results continue to appear. The technology and performance level of compressors is changing with each passing day. There are many types of compressors. According to different working principles, refrigeration compressors can be divided into fixed displacement compressors and variable displacement compressors.
Features:
1. The refrigeration capacity of most fully enclosed piston compressors does not exceed 0.5KW, which are mainly used in household refrigerators/freezers and small commercial refrigeration equipment.
2. The cooling capacity of the scroll compressor is 0.75～15KW (excluding special models), and most of them are between 3～5KW. The most applications are in small household air conditioners and commercial air conditioners. This type of compressor is not used for refrigeration conditions at minus 5 degrees.
3. Centrifugal refrigeration compressors are mainly used for chillers under air conditioning conditions.
4. The single screw compressor has a cooling capacity of 30kw-1500kw, which can be used in cold storage, artificial ice rinks, and chillers.
5. The semi-hermetic piston refrigeration compressor has a wide range of uses. The cooling capacity of a single machine is from 3kw-100kw. At the same time, multiple heads can be used in parallel, so the cooling capacity range from 3kw-1000kw can be provided. , And can be applied to air conditioning conditions.
6. Turning on the piston refrigeration compressor is only commonly used in cold storage, a very small number of air-conditioning chillers.
