【Jiangsu Wuxi Xishan Air Conditioning Recycling and Purchase Analysis of Air Conditioning Systems】The system analysis of air-cooled heat pump units involves more than comparing parameters such as cooling capacity, heating capacity, COP value, noise, operating weight, and dimensions. It also requires analyzing the compressor types, condenser types and arrangements, thermal expansion valve configurations, evaporator types, defrosting methods, energy regulation methods, and the automatic control and safety protection of the heat pump system, comparing the respective advantages and disadvantages in system configuration. Compressor types: The main compressor types for air-cooled heat pumps are piston, scroll, and screw types. Considering the characteristics of heat pump operation, such as long runtime and high compression ratio, the author believes that scroll and screw compressors will become the mainstream of heat pump compressors. The reasons are: 1. Scroll and screw compressors have fewer moving parts compared to piston compressors, which reduces the friction loss and improves the overall efficiency of the unit.
