The invention relates to a hybrid electric vehicle heat pump air conditioning system which comprises a heat pump air conditioning loop which comprises an air conditioning compressor, a first heat exchanger, an in-vehicle condenser, a first electronic expansion valve, an in-vehicle evaporator and a gas-liquid separator which are sequentially communicated with one another. The warm air core body loop is connected with the engine cooling loop through a four-way valve, the warm air core body loop comprises a first circulating water pump and a warm air core body which are communicated with each other, and a first heat exchanger is communicated between the first circulating water pump and the warm air core body. According to the direct bypass heat pump air conditioner, the air conditioner compressor, the first heat exchanger, the in-vehicle condenser, the first electronic expansion valve, the in-vehicle evaporator and the gas-liquid separator of the heat pump air conditioner loop are connected with one another to form the direct bypass heat pump air conditioner. After the air conditioner compressor is started, the in-vehicle condenser is directly heated through the refrigerant, the in-vehicle condenser directly heats the passenger compartment, the heating speed of the passenger compartment can be increased, heat loss is reduced, and energy consumption of the air conditioner is reduced.
