Problems solved by technology

[0002] In the prior art, after the two-stage enthalpy-increasing compressor with dual rotors performs gas replenishment and enthalpy increase, the pressure and flow rate of the refrigerant in different stages in the medium-pressure gas flow channel are different, while the cross-sectional area of ​​the medium-pressure gas flow channel is the same Yes, this leads to a large airflow pulsation between the discharge of the low-pressure compression component of the first stage and the suction of the high-pressure compression component of the second stage, which affects the suction of the compressor and the fullness of the exhaust, thereby reducing the compressor efficiency and compressor energy efficiency, increasing energy consumption

Abstract

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.

Description

technical field [0001] The invention relates to the fields of air conditioners and heat pumps, and more specifically, to a compressor, an air conditioner system with the compressor, and a heat pump water heater system. Background technique [0002] In the prior art, after the two-stage enthalpy-increasing compressor with dual rotors performs gas replenishment and enthalpy increase, the pressure and flow rate of the refrigerant in different stages in the medium-pressure gas flow channel are different, while the cross-sectional area of ​​the medium-pressure gas flow channel is the same Yes, this leads to a large airflow pulsation between the discharge of the low-pressure compression component of the first stage and the suction of the high-pressure compression component of the second stage, which affects the suction of the compressor and the fullness of the exhaust, thereby reducing the compressor Efficiency and compressor energy efficiency, which increases energy consumption. ...
