Abstract
A heat pump air-conditioning system includes a HVAC assembly, a compressor, an outdoor heat exchanger, and a first plate heat exchanger. The HVAC assembly includes an indoor condenser, an indoor evaporator, and an damper mechanism. The compressor communicates to the indoor condenser. The indoor condenser communicates to the outdoor heat exchanger and further to the outdoor heat exchanger through a first enthalpy-increased branch. The outdoor heat exchanger communicates to the indoor evaporator and further to a moderate-pressure air inlet of the compressor through a second enthalpy-increased branch. The indoor evaporator communicates to a low-pressure air inlet of the compressor. The first enthalpy-increased branch and the second enthalpy-increased branch exchange heat by using the first plate heat exchanger. The second enthalpy-increased branch is provided with a first expansion valve. The outdoor heat exchanger is in communication with the first plate heat exchanger through the first expansion valve.
