    摘要: The supercritical refrigerating apparatus has refrigerant bypass means for bypassing a heat exchanger according to a physical value of the refrigerant. Therefore, the temperature of refrigerant on a suction side of the compressor becomes lower than that of refrigerant sucked into the compressor via the heat exchanger. As a result, the refrigerant temperature in a refrigerant passage extending from a suction side to a discharge side of the compressor is decreased, thereby preventing breakage of the compressor.

    摘要: An air conditioning system having an evaporator 8 at a location upstream from a compressor. When a compressor is stopped, a refrigerant inlet is closed by an electromagnetic valve 28 and a refrigerant outlet is closed by a check valve 29. A pressure in the closed passageway is detected by a pressure sensor 22. A leakage of refrigerant at the evaporator is reliably detected, which allows the leakage of the refrigerant to be quickly noticed.

    摘要: According to the present invention, when leakage of refrigerant is detected during operation of an air conditioning apparatus for a vehicle, air outlets for a passenger and a solenoid valve for an air passage are closed. Accordingly, a compressor is stopped after a predetermined time has elapsed since the solenoid valve is closed. In this way, refrigerant within an evaporator is sucked and discharged. Consequently, an amount of refrigerant leaking from an air conditioner casing due to damage of the evaporator can be reduced.

    摘要: In an air conditioner according to the present invention, the first and second electromagnetic valves are disposed at the outlet port and the inlet port of the condenser, which is disposed at a position away from the passenger compartment and may be easily damaged by the outer force when the vehicle collides. The first and second electromagnetic valves are closed when the outer force applied to the vehicle is equal to a predetermined value or more. In this way, an amount of leaking refrigerant is as much as the amount accumulated in the air conditioning devices at most, thus making it possible to reduce the leakage of the refrigerant.

    摘要: In a refrigeration cycle device for a vehicle, a weak-inflammability refrigerant that does not ignite at a high-temperature heat source mounted in an engine compartment of the vehicle in a refrigerant single state is circulated in a refrigerant cycle. The refrigerant cycle includes a compressor for compressing and discharging the refrigerant. The compressor includes an oil separator that is located at a refrigerant discharge side of the compressor to separate a lubrication oil from the refrigerant and to return the separated lubrication oil to an interior of the compressor, a shutting portion configured to shut a reverse flow of the refrigerant at a refrigerant suction side of the compressor, and a driving portion located to drive the shutting portion. Furthermore, the driving portion causes the shutting portion to shut the reverse flow of the refrigerant when the refrigerant cycle is damaged.

    摘要: A gas-liquid separator (accumulator) is arranged at a refrigerant suction side of a compressor of a refrigerant cycle system mounted in a vehicle. The gas-liquid separator includes a gas-liquid separation portion for separating refrigerant into gas refrigerant and liquid refrigerant, and a liquid refrigerant storage portion for storing therein the separated liquid refrigerant. In the gas-liquid separator, the gas-liquid separation portion is arranged approximately vertically, and the liquid refrigerant storage portion is arranged approximately horizontally with respect to the approximately vertically arranged gas-liquid separation portion. Therefore, mounting performance of the gas-liquid separator in the vehicle can be effectively improved while gas-liquid separation can be accurately performed.
