发明名称 COMPRESSOR, AIR CONDITIONER SYSTEM COMPRISING THE COMPRESSOR AND HEAT PUMP WATER HEATER SYSTEM
摘要 Provided is 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 gas discharge passageway, an enthalpy-increasing component, a high-pressure compression component, a medium-pressure gas passageway and a high-pressure chamber gas discharge passageway. The medium-pressure gas passageway comprises a passageway section at the side toward the low-pressure chamber gas discharge passageway and a passageway section at the side toward the high-pressure chamber gas suction passageway, wherein a ratio between a minimum cross sectional area of the passageway section at the side toward the low-pressure chamber gas discharge passageway and a minimum cross sectional area of the passageway section at the side toward the high-pressure chamber gas suction passageway is ranged from 1.4 to 4. In the compressor, the pressure fluctuation and the flow velocity fluctuation of the refrigerant are relatively smaller, which can improve the first-stage gas discharge plumpness and the second-stage gas suction plumpness, and increase the gas replenishment volume, thereby improving the working efficiency and the energy efficiency ratio of the compressor, and reducing the energy consumption.
