摘要： A refrigerant cycle system includes a first heat-exchanging portion for condensing gas refrigerant discharged from a compressor, a gas-liquid separator into which all of refrigerant after passing through the first heat-exchanging portion and a part of gas refrigerant discharged from the compressor are introduced, and a second heat-exchanging portion for cooling and condensing refrigerant flowing from the gas-liquid separator. Because all of the condensed refrigerant from the first heat-exchanging portion is introduced into the gas-liquid separator, a passage area of a gas refrigerant introduction passage for introducing gas refrigerant from the compressor into the gas-liquid separator can be set relatively large. Therefore, a dimension difference of the gas refrigerant introducing passage in manufacturing is not greatly affected to an adjustment of a liquid refrigerant amount in the gas-liquid separator.

摘要： The internal heat exchanger 7 is provided which exchanges heat between the refrigerant of low pressure and the refrigerant of high pressure, and the pre-load adjusting mechanism of the expansion valve 5 is abolished. Due to the above structure, the refrigerant flowing into the expansion valve 5 is cooled in the internal heat exchanger 7, and enthalpy of the refrigerant flowing into the evaporator 6 is reduced. On the contrary, the refrigerant sucked into the compressor 1 is heated. Accordingly, a difference in enthalpy between the refrigerant at the inlet and the refrigerant at the outlet of the evaporator 6 can be made large, and the heat absorbing capacity of the evaporator 6 can be enhanced, and further it becomes possible to give the degree of superheat to the refrigerant sucked into the compressor 1. Therefore, even if the pre-load adjusting mechanism is abolished, the vapor-compression-type refrigerating machine can be stably operated.

摘要： A refrigeration cycle for a vehicle air conditioning system allows the refrigerant-to-refrigerant heat exchanger to exchange heat between a high-pressure liquid refrigerant, which is delivered from the sub-cooling condenser and directed to the evaporator, and a low-pressure refrigerant having a liquid and gas phase, which is delivered from the evaporator and directed to the compressor. The refrigeration cycle also allows the amount of the refrigerant circulating through the refrigeration cycle to be adjusted in response to the level of sub-cooling upstream of a throttle hole of a reverse sub-cooling control valve to thereby indirectly control the level of superheating on the outlet side of the evaporator. This provides improvements both in the amount of heat to be exchanged between refrigerants in the refrigerant-to-refrigerant heat exchanger and the cooling performance of the evaporator.

摘要： In an expansion valve integrated with a electromagnetic valve, the expansion valve has an inlet refrigerant path for introducing refrigerant, a restriction path for decompressing and expanding the refrigerant, a valve element for adjusting an opening degree of the restriction path, a valve element operating unit, and an outlet refrigerant path for discharging the refrigerant. The outlet refrigerant path is opened or closed by the electromagnetic valve. When the electromagnetic valve is closed, the valve element operating unit closes the valve element in the restriction path, based on a refrigerant pressure in a space between a valve element of the electromagnetic valve and the restriction path. The space communicates with the inlet refrigerant path through a minute communication hole.
