摘要： According to the present invention, in a gas injection type heat pump apparatus, the high-pressure side pressure of refrigeration cycle is detected in a heating operation, and an upper limit value of an amount of air passing through an inside heat exchanger is determined based on the detection value. The upper limit value and a set air amount set by an air amount switching lever are compared. When the set air amount is larger than the upper limit value, the amount of the air passing through the inside heat exchanger is restricted within the upper limit value. In this way, the high-pressure side pressure increases, and an intermediate pressure in a gas-liquid separator also increases. Therefore, the gas injection amount can be increased, and a heating capacity can be effectively improved.

摘要： When heating the passenger compartment of a vehicle during cold weather, an air switching outlet is operated to allow the entry of outside air with an interior blower being operated to facilitate the entry of the outside air. A condenser door is operated to close an air passage of the condenser and a bypass passage is opened so that outside air flows to the passenger compartment of the vehicle while bypassing the condenser. Further, only a defogging outlet is opened and the incoming air is blown out from this defogging outlet toward the windshield of the vehicle so that a low humidity air curtain is formed proximate to the inner surface of the windshield. After completing the warm-up of the heat pump cycle, the condenser door is switched such that the air blown in by the blower passes the interior condenser to start the heating of the passenger compartment.

摘要： A heat pump cycle system which can switches cooling operation and heating operation for a compartment includes a first inside heat exchanger and a second inside heat exchanger disposed in an air conditioning case. The first inside heat exchanger is disposed in the air conditioning case at a downstream air side of the second inside heat exchanger, while being arranged in line in a flow direction of refrigerant. The first inside heat exchanger is upstream from the second inside heat exchanger in the flow direction of refrigerant during the heating operation. In the heat pump cycle system, an expansion valve is controlled so that coefficient of performance in each operation becomes approximately maximum. Thus, during the heating operation of the heat pump cycle system, a lower limit temperature of air blown from the inside heat exchangers can be increased so that temperature of air blown into the compartment is increased, while the coefficient of performance is improved.
