摘要： In a heat exchanging apparatus for a vapor compression refrigerant cycle, an internal heat exchanger is attached to an end of a radiator. The internal heat exchanger is arranged such that high-pressure refrigerant passages are closer to the radiator than low-pressure refrigerant passages. The heat exchanging apparatus can be mounted on a vehicle such that the radiator receives cooling air more than the internal heat exchanger. Because the internal heat exchanger performs heat exchange between high-pressure refrigerant and low-pressure refrigerant, performance of the internal heat exchanger is not degraded even if it is located at a part receiving less cooling air. Thus, the heat exchanging apparatus is easily mounted on a vehicle by integrating the internal heat exchanger with the radiator, without reducing a cooling capacity of the radiator.

摘要： An air-conditioner includes a compressor, a radiator, an evaporator, an ejector, and a separator. The compressor compresses refrigerant and variably controls an amount of the refrigerant. The radiator cools high-pressure refrigerant. The evaporator cools air blowing into a passenger compartment of a vehicle. The ejector having a nozzle jets the refrigerant at high speed. The separator separates the refrigerant into gas refrigerant and liquid refrigerant. An opening degree of a throttle of the nozzle in the ejector becomes larger so as to increase a cooling performance of the air-conditioner when the amount of the refrigerant discharged from the compressor is smaller than a maximum amount of the refrigerant.

摘要： In an ejector refrigerant cycle, even if refrigerant is super-heated in an evaporator, super-heated gas refrigerant does not directly flow into a gas-liquid separator, so that boiling of refrigerant does not occur in the gas-liquid separator due to evaporation of refrigerant in the gas-liquid separator. When an equivalent inner diameter (D) of a tank body of the gas-liquid separator is set in a range of 2 cm–6 cm, and when a ratio of a vertical dimension (H) of the tank body to the equivalent inner diameter (D) thereof is larger than 1, a wall thickness of the tank body can be reduced while gas-liquid separation performance in the gas-liquid separator can be improved.

摘要： A silencer for a refrigeration cycle system is disclosed. The silencer includes a silencing chamber 15a formed in a housing 16, an inlet pipe 20 connected to the housing 16 to allow the refrigerant to flow into the silencing chamber 15a, and an outlet pipe 21 connected to the housing 16 to allow the refrigerant to flow out of the silencing chamber 15a. The direction in which the inlet pipe 20 is connected to the housing 16 and the direction in which the outlet pipe 21 is connected to the housing 16 cross each other. A bend 21c projected into the silencing chamber 15a and curved toward the upstream end 20b of the inlet pipe 20 is formed at the upstream end 21b portion of the outlet pipe 21. The bend 21c is formed with an opening 21d to open the inside part thereof. As a result, the refrigerant that has flowed into the silencing chamber 15a can be guided smoothly to the outlet pipe 21 while at the same time avoiding a case in which the bend 21c suppresses the interference of the pressure wave.

摘要： The present invention relates to a refrigerating system and a method of operating a refrigerating system. The refrigerating system includes a compressor, a gas cooler used as a heat-dissipation type heat exchanger, an expansion valve used as a throttling means, an evaporator used as a heat-absorption type heat exchanger and an accumulator, which are connected in series with each other to form a closed circuit. The closed circuit is adapted so that the higher pressure of the closed circuit becomes the supercritical pressure of a refrigerant circulating the closed circuit. This has a control characteristic property wherein the lower evaporating pressure increases as the higher pressure increases. The lower evaporating pressure and the higher pressure are detected, respectively, and if the detected value of the lower evaporating pressure is lower than a target value for the lower evaporating pressure determined based on the above control characteristic property in correspondence to the detected value of the higher pressure, the discharge capacity of the compressor is reduced so that the lower evaporating pressure coincides with the target value.

摘要： In a CO.sub.2 refrigerant cycle, a lubricating oil for a compressor has a compatibility relative to CO.sub.2 refrigerant, and the compatibility of the lubricating oil relative to the CO.sub.2 refrigerant at a pressure lower than a critical pressure of the CO.sub.2 refrigerant is lower than that at a pressure higher than the critical pressure of the CO.sub.2 refrigerant. Thus, in a low-pressure side such as an accumulator of the CO.sub.2 refrigerant cycle, because a liquid lubricating oil is separated with a liquid CO.sub.2 refrigerant, only the lubricating oil can be readily introduced into a suction side of the compressor, and it can prevent the liquid CO.sub.2 refrigerant from being sucked into the compressor. As a result, it can prevent a damage to the compressor while preventing deterioration of coefficient of performance of the CO.sub.2 refrigerant cycle.
