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.

摘要： A refrigeration cycle is switched from a refrigeration cycle circuit to a hot gas heater circuit to make the hot gas discharged from a compressor flow into an evaporator and heat the vehicle passenger compartment, at which time, when a suction pressure (Ps) of the compressor becomes a low pressure below a first predetermined pressure, the discharge volume (Vc) of the compressor is made larger to ensure a sufficient auxiliary heating performance. Further, when the hot gas is made to flow into the evaporator to heat the vehicle passenger compartment, if the suction pressure (Ps) of the compressor becomes a higher pressure over a second predetermined pressure, the discharge volume (Vc) of the compressor is made smaller to protect the refrigeration cycle parts and lighten the ON, OFF shock.

摘要： A decompressing device for decompressing refrigerant that is discharged from a compressor is provided at an inlet of a hot-gas bypass passage. The refrigerant flows in the hot-gas bypass passage after being decompressed by the decompressing device to bypass a condenser at a heating mode. In this case, because the refrigerant flows in the hot-gas bypass passage with a temperature that is lowered by the decompression, heat loss at a pipe portion of the hot-gas bypass passage is effectively decreased.

摘要： A refrigerating cycle apparatus is used in an air-conditioning system of an automotive vehicle, which is capable of operating in a hot gas bypass heating mode. Here, the discharge side of a compressor is directly connected through a hot gas bypass conduit to the inlet side of an evaporator. The evaporator acts as a radiator, heated by gas refrigerant. The compressor is stopped during operation of the apparatus in this heating mode when a physical quantity representing the high-side pressure at the compressor discharge side rises above a set value. The compressor is restarted when a physical quantity representing a heating capacity (for example the high-side pressure) falls below a set value which indicates that there is no heating capacity in the stopped state of the compressor. As a result, the heating capacity obtained through hot gas bypass can be controlled well without frequent stopping and restarting of the compressor.

摘要： In a refrigerant cycle system, a refrigerant discharge side of a compressor is directly connected to a refrigerant inlet side of an evaporator through a hot-gas bypass passage so that the evaporator is used as a radiator during a heating mode due to the hot-gas bypass. A physical amount of refrigerant, such as a high-pressure side refrigerant pressure, flowing through the hot-gas bypass passage is detected. When the high-pressure side refrigerant pressure is decreased to a value corresponding to a refrigerant shortage area, a refrigerant shortage is determined and the compressor is stopped by a control unit. Thus, during the heating mode due to the hot-gas bypass, when a refrigerant leakage is caused in the refrigerant cycle system, the compressor is accurately protected.

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.
