摘要: An ejector type refrigerating cycle comprises a compressor, a heat radiating device, an ejector, and a first vaporizing device, which are connected in a circuit to form a refrigerating cycle. A bypass passage is provided between an inlet port and a suction port of the ejector, so that a part of the refrigerant is bifurcated to flow through the bypass passage. A second vaporizing device is provided in the bypass passage. An internal heat exchanger is further provided between an outlet side of the heat radiating device and the inlet side of the ejector, so that the enthalpy of the high-pressure refrigerant from the heat radiating device is reduced, to thereby increase an enthalpy difference between the inlet side and outlet side of the first and second vaporizing devices. As a result, the cooling capability by the both vaporizing devices can be improved.

摘要: In an ejector cycle having an ejector for decompressing refrigerant, a check valve is disposed in an oil return passage through which refrigerant including a lubrication oil is introduced from a refrigerant outlet side of an evaporator to a refrigerant suction side of a compressor while bypassing the ejector. When the lubrication oil amount staying in the evaporator reduces, the check valve is automatically closed, and a normal operation mode of the ejector cycle is automatically set. On the contrary, when a large amount of lubrication oil stays in the evaporator, the check valve is automatically opened, and an oil return mode is automatically set. Therefore, the lubrication oil staying in the evaporator can be controlled equal to or lower than a predetermined amount, thereby effectively returning the lubrication oil to the compressor.

摘要: In a vapor compression refrigeration system, an evaporator and a gas-liquid separator are received in a common casing, so that the gas-liquid separator and the evaporator are placed close to each other. Thus, it is possible to limit heat absorption of the liquid phase refrigerant from the atmosphere to reduce the heat loss upon discharge of the refrigerant from the gas-liquid separator. Also, it is possible to reduce pressure loss in a refrigerant passage between the gas-liquid separator and the evaporator.
