    摘要: A vehicle air conditioner includes: a heat pump cycle including an inside heat exchanger performing heat exchange between a refrigerant and a blown air that is to be blown into a vehicle compartment, and a refrigerant-circuit switching device that switches between a refrigerant circuit of a cooling mode in which the blown air is cooled in the inside heat exchanger and a refrigerant circuit of a non-cooling mode in which the blown air is not cooled in the inside heat exchanger; and a refrigerant-circuit controller that controls an operation of the refrigerant-circuit switching device. The refrigerant-circuit controller performs a cooling-mode unallowable control in which the refrigerant circuit of the cooling mode is prohibited from being selected after the non-cooling mode is selected during a predetermined time period.

    摘要: An air conditioner includes a refrigerant circuit, an electromagnetic induction heating unit, and a control unit. The refrigerant circuit has a compressing mechanism with an adjustable operating capacity, a heat source side heat exchanger, an expansion mechanism, and a utilization side heat exchanger. The electromagnetic induction heating unit heats a refrigerant piping and/or a member that is in thermal contact with a refrigerant that flows through the refrigerant piping. The control unit sets the electromagnetic induction heating unit to a forced inhibit state if any one of a condition in which the electromagnetic induction heating unit has been manually set to operation inhibited; a condition in which an air conditioning load is small; and a condition in which an amount of circulating refrigerant is small is satisfied.

    摘要: A heat pump system includes a refrigerant circuit and a controller. In a heating operation, the usage-side expansion valve is controlled so that a degree of subcooling of outlet refrigerant of the usage-side heat exchanger is equal to a predetermined target degree of subcooling. In a refrigerant recovery control, the heat-source-side expansion valve is controlled so that a degree of superheat of outlet refrigerant of the heat-source-side heat exchanger is equal to a predetermined target degree of superheat, the predetermined target degree of superheat is changed so that the outlet refrigerant of the heat-source-side heat exchanger is wet when the usage-side expansion valve is opened greater than a predetermined opening degree at a start of refrigerant recovery, and change in the predetermined target degree of superheat is cancelled when the usage-side expansion valve is closed smaller than a predetermined opening degree at an end of refrigerant recovery.
