The invention discloses a gas-replenishing enthalpy-increasing electric vehicle air-conditioning heat pump system and an electric vehicle equipped with the same. The gas-replenishing enthalpy-increasing electric vehicle air-conditioning heat pump system comprises a compressor, an outdoor heat exchanger, a first indoor heat exchanger, a second indoor heat exchanger, a gas-liquid separator, a firstthermal expansion valve, a second thermal expansion valve, a third thermal expansion valve, a first electromagnetic valve, a second electromagnetic valve, a first cooler and a compressor gas-replenishing enthalpy-increasing module, wherein the compressor gas-replenishing enthalpy-increasing module comprises the third thermal expansion valve and an economizer. The gas-replenishing enthalpy-increasing electric vehicle air-conditioning heat pump system has the gas-replenishing enthalpy-increasing heating state and the non-gas-replenishing non-enthalpy-increasing heating state. The gas-replenishing enthalpy-increasing electric vehicle air-conditioning heat pump system has the following beneficial effects that by use of the compressor gas-replenishing enthalpy-increasing module, the normal heating operation of the electric vehicle in a low-temperature environment can be satisfied.
Description
technical field [0001] The invention relates to an electric vehicle air-conditioning heat pump system for supplementing air and adjusting enthalpy and an electric vehicle comprising the same. Background technique [0002] Due to the increasingly prominent environmental problems, electric vehicles are becoming more and more popular as an alternative to traditional engine vehicles. Different from traditional cars, electric vehicles cannot use the waste heat of the engine for effective heating, and at the same time bring great challenges to the thermal management system of electric vehicles. There are problems in the environment that cannot guarantee normal heating. Contents of the invention [0003] The object of the present invention is to provide an electric vehicle air-conditioning heat pump system and an electric vehicle including the same to solve the problem of the influence of the existing electric vehicle air-conditioning system on the cruising range of the electric...
