Refrigeration compressors have five major technological

Refrigeration compressors have five major technological developments around energy saving CFCs and HCFCs refrigerants that have a destructive effect on the ozone layer are phase-out substances specified in the Montreal Protocol, and have been gradually replaced by HFCs and natural refrigerants in the late 1980s. The compressor has been greatly improved in technology to adapt to alternative refrigerants, and developed H134s refrigerant compressors such as R134a, R404A, R407C and R410A, and HCs refrigerant compressors such as R600a and R290. CO2 transcritical cycle compressors have been successfully used in automobile air conditioners and heat pump water heaters. Ordinary CO2 compressors and NH3 cascade systems are being used for commercial refrigeration, and closed NH3 compressors are being used in air conditioners and refrigerators. 3 Economizer gas supply and single-stage multi-stage compression The normal working condensation and evaporation temperature difference of the single-stage compression refrigeration system is 40-60 ℃. In cryogenic and low temperature air source heat pumps, this temperature difference can reach 75 ℃. In order to enable a single compressor to produce a large temperature difference, screw compressors and scroll compressors of the Economizer Air Supply (EVI) have been mass-produced, and piston compressors and rolling piston compressors for air supply have also been studied. Single-cylinder two-stage compression multi-cylinder piston compressors are becoming more and more common in refrigeration equipment. Single-cylinder two-stage compression two-cylinder rolling piston compressors have been successfully developed and applied. The single-machine three-stage compression centrifugal compressor is already a symbol of high energy efficiency. 4Special and specialized compressors The shaft seal is the core component of the bus air-conditioning compressor, which is still dominated by domestic brands. Rolling piston compressors for air source heat pump water heaters have been mass produced. The compressors for air conditioners and refrigerators driven by various special power sources such as 12V, 24V and 48V DC have also been mass produced, and are mainly rolling piston type, piston type and triangular rotor type. Micro compressors for cooling of microelectronics and air conditioning for human bodies are also under development. In short, the compressor technology should adapt to the changes of the times, constantly improve its performance, continue to expand the application field, and constantly develop new compressors. 5 Expand the capacity range and application areas The longest-lasting and most adaptable reciprocating piston compressor is a general-purpose model with a wide range of capacity. It continues to occupy the top position in the field of refrigerators and commercial freezers, and is subject to rolling piston, scroll, and screw compressors in the field of air conditioning Challenge. The compact centrifugal compressor with magnetic bearing is a highly mechatronic product, which is used in chiller units and overlaps with the capacity of the screw compressor. Large-scale scroll compressors and fully enclosed screw compressors have been mass-produced, and the two have been connected in terms of capacity. The output of scroll compressors for refrigeration continues to increase, and three-screw compressors have also been put on the market. The capacity range of the rolling piston compressor has been expanded up to 14hp and down to 1 / 8hp. In order to solve the problem of leakage and wear after using R410A, the research on the deformation structure of rolling piston compressors is extremely active, and the swing rotor compressor has been applied in engineering.
