Compressor, air conditioner system comprising the compressor and heat pump water heater system

摘要

A compressor, an air conditioner system comprising the compressor and a heat pump water heater system. The compressor comprises: a low-pressure compression component, a medium-pressure chamber, a low-pressure chamber air discharge passageway, an enthalpy-increasing component, a high-pressure compression component, a medium-pressure air passageway and a high-pressure chamber air discharge passageway. The medium-pressure air passageway comprises a side passageway section of the low-pressure chamber air discharge passageway and a side passageway section of a high-pressure chamber air suction passageway, and a ratio between a minimum cross section area of the side passageway section of the low-pressure chamber air discharge passageway and a minimum cross section area of the side passageway section of the high-pressure chamber air suction passageway is from 1.4 to 4. In the compressor, the pressure impulse and the flow speed impulse of the refrigerant are relatively small, the first-stage air discharge plumpness and the second-stage air discharge plumpness can be improved, and the air supply quantity can be improved; therefore, the working efficiency and the energy efficiency of the compressor are enhanced, and the energy consumption is reduced.
