    摘要： In a vehicle air conditioner, a refrigerant cycle system is constructed to switch a cooling refrigerant cycle where an interior heat exchanger is used as an evaporator, and a hot gas heater cycle where the interior heat exchanger is used as a radiator. Further, it is determined whether the interior heat exchanger has a quantity of retained water in a heating mode due to the hot gas heater cycle. When it is determined that the quantity of retained water is in the interior heat exchanger in the heating mode, operation of a compressor of the refrigerant cycle system is intermittently controlled so that temperature of air blown from the interior heat exchanger becomes lower than temperature of a vehicle windshield.

    摘要： In the air conditioner of the present invention, both the normal cooling mode operation, in which refrigerant discharged from the compressor 1 is made to flow in the condenser 2, and the heating mode operation conducted by the hot gas bypass, in which refrigerant is made to bypass the condenser and directly flow in the evaporator 4 via the throttle 17, can be conducted. Before this heating mode operation, after the compressor is turned on for a predetermined period of time in the cooling mode, the compressor is turned off for a predetermined period of time, so that refrigerant residing in the condenser can be recovered into the hot gas cycle, and then a hot gas operation, which is the heating mode, is conducted.

    摘要： A refrigeration cycle system is disclosed. Upon generation of a start signal for a hot gas heater cycle, the cooling mode is first started thereby to start the dormant refrigerant recovery mode (S10) and, upon an increase in the compressor discharge pressure Pd to a predetermined setting P1, the cooling mode is ended and the compressor is switched to the off mode (S20, S30). Upon the lapse of a predetermined time ta in the off mode, the off mode is ended (S40) and the heating mode with the hot gas heater cycle is started.

    摘要： A vehicle air conditioner that inhibits re-evaporation of condensed water on the surface of an evaporator that might fog the inner surface of the vehicle windshield during operation of a hot gas heating cycle heating mode. It is possible to switch operation of a cooling mode by an ordinary refrigerating cycle by opening the inlet side of a condenser and closing the inlet side of a hot gas bypass passage. It is also possible to switch the operation of the heating mode by closing the inlet side of the condenser and opening the inlet side of the hot gas bypass passage. When it is determined during operation of the heating mode that the windshield will fog, operation of the air conditioning compressor is interrupted by the air conditioning control unit so that the temperature of an evaporator reaches no more than a predetermined value.

    摘要： A refrigerating cycle apparatus that inhibits system corrosion and abnormally high pressure during startup of a first refrigerant circuit by preventing air from penetrating into a refrigerant compressor during low-temperature startup of a second auxiliary refrigerant circuit. An apparatus evaporator heats air flowing through an air conditioning duct as a high temperature/high pressure gas refrigerant discharged from an engine-driven compressor is guided through a pressure-reducing unit and the evaporator, bypassing a condenser. Thereafter, the refrigerant is returned to the compressor, which is automatically stopped when a compressor suction pressure, or a physical quantity representative of the suction pressure, becomes lower than a predetermined value.

    摘要： A refrigeration cycle for a vehicle air conditioner has a bypass passage between a compressor and an evaporator. In a heating mode, high-temperature gas refrigerant discharged from the compressor is directly introduced into the evaporator through the bypass passage while bypassing a condenser to improve a heating performance of the air conditioner. When a refrigerant recovery mode in which refrigerant staying in the condenser is forced to be discharged and introduced into the evaporator is set, a passage between the condenser and the evaporator in which a thermostatic expansion valve is disposed is controlled to be opened a predetermined amount. As a result, refrigerant staying in the condenser is securely returned to the evaporator even when a temperature of outside air is extremely low and the expansion valve is closed.
