    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: 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: 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: In a vehicle air conditioner having front and rear air conditioning units, a refrigerant cycle includes front and rear evaporators for cooling air in a cooling mode, a hot-gas bypass passage through which hot-gas refrigerant discharged from a compressor flows into the front evaporator while bypassing a condenser in a heating mode, and a fixed throttle between the condenser and the front evaporator for decompressing refrigerant flowing from the condenser in the cooling mode. Further, a refrigerant outlet side of the fixed throttle and a refrigerant outlet side of the hot-gas bypass passage are joined to a refrigerant pipe, and a refrigerant outlet of the refrigerant pipe is connected to a refrigerant inlet of the front evaporator. Therefore, a refrigerant pipe structure of the refrigerant cycle can be made simple.
