    摘要: According to the present invention, in a gas injection type heat pump apparatus, the high-pressure side pressure of refrigeration cycle (21) is detected in a heating operation, and an upper limit value (BP) of an amount of air passing through an inside heat exchanger (14) is determined based on the detection value. The upper limit value (BP) and a set air amount (BO) set by an air amount switching lever (51) are compared. When the set air amount (BO) 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: According to the present invention, in a heating operation where a heating indoor heat exchanger (12) function as a condenser and an outdoor heat exchanger (22) functions as an evaporator, an air amount supplied by a blower (4) is reduced when a predetermined amount of frost is or may be deposited on the outdoor heat exchanger (22) in an outside air introduction mode where an outside air is supplied into a passenger compartment. Accordingly, a heating load is reduced to thereby reduce an endothermic amount in the outdoor heat exchanger (22). As a result, a frost deposition speed is reduced, and a deposited frost limit is increased, thereby extending a heating operation period.

    摘要: An air conditioner for a vehicle includes a heat pump system for heating and cooling. The air conditioner includes a ventilation passage (14) for ventilating air from a passenger compartment (13) of the vehicle outside of the vehicle. An accelerating system is provided with the heat pump system for accelerating the evaporation of a refrigerant during air cooling or the condensation of a refrigerant during air heating by using involved energy recovered from air exhausted outside of said vehicle through the ventilation passage (14). Thereby, the air conditioner increases the heating and cooling ability and reduces the energy necessary for maintaining a constant temperature in the passenger compartment (13).
