摘要: In an ejector cycle with an ejector including a nozzle for decompressing refrigerant, a variable throttle device is disposed upstream from the nozzle to decompress and expand high-pressure refrigerant flowing from a condenser. For example, the variable throttle device decompresses the high-pressure refrigerant in a gas-liquid two-phase state at an upstream position from the nozzle of the ejector. In addition, the variable throttle device includes a back pressure chamber having an inner pressure that changes by sensing a refrigerant temperature at a refrigerant outlet side of an evaporator, and a pressure introducing means for introducing a refrigerant pressure of a refrigerant outlet side of the evaporator to a side opposite to the back pressure chamber with respect to a diaphragm. Therefore, a pressure difference between the back pressure chamber and the side opposite to the back pressure chamber can be made smaller.

摘要: An ejector cycle with an ejector includes a nozzle for decompressing refrigerant. A receiver for storing refrigerant is disposed at a refrigerant outlet side of a condenser. A bypass passage and a switching valve for opening and closing the bypass passage are provided so that high-temperature refrigerant discharged from a compressor is introduced into an evaporator while bypassing the condenser in a defrosting operation. When the defrosting operation is set, the switching valve is opened while a fan for blowing cool air to the condenser is operated. A part of refrigerant discharged from the compressor flows into the evaporator to remove frost on a surface of the evaporator.

摘要: A bypass valve 81 is opened until a predetermined period of time elapses after compressors 10a, 10b are stopped so as to equalize the pressure of a refrigerant circuit on a condenser 20 side with the pressure of a refrigerant circuit on an evaporator 30 side and, after the bypass valve 81 is closed, at least either of a refrigerant circuit 91 connecting to the compressor 10aand a refrigerant circuit 92 connecting to the compressor 10b is opened by opening a three-way valve 90 so that the refrigerant circuit on the condenser 20 side is made to communicate with the refrigerant circuit on the evaporator 30 side via the compressor 10 whereby, as the pressure equalized state can be maintained, it is possible to prevent the accumulation of a large amount of refrigerating machine oil on suction sides of the compressors 10 while the compressors 10 are stopped, thereby making it possible to prevent damage to the compressors 10 due to excessive compression when activated.

摘要: In an ejector cycle with an ejector including a nozzle for decompressing refrigerant, a refrigerant outlet is provided in an evaporator at a position upper than a refrigerant inlet. Therefore, a circulation performance of refrigerant flowing in the evaporator can be improved. Accordingly, even when a pumping capacity generated in the ejector becomes smaller, a sufficient amount of refrigerant can be drawn into the ejector from the evaporator. Thus, a refrigerant amount supplied to the evaporator can be effectively increased. Further, a control unit controls an amount of cooling air supplied to a condenser based on the temperature of the cooling air, to control a refrigerant state to be introduced to the nozzle. In this case, a pressure increasing amount in the ejector can be effectively increased, and consumption power in the compressor can be effectively increased.

摘要: In an ejector cycle with an ejector including a nozzle for decompressing refrigerant, a variable throttle is disposed upstream from the nozzle of the ejector to decompress and expand high-pressure refrigerant flowing from a radiator. For example, the variable throttle decompresses and expands the high-pressure refrigerant in a gas-liquid two-phase state at an upstream position from the nozzle of the ejector. The variable throttle controls a throttle opening degree so that a refrigerant super-heating degree at a refrigerant outlet side of an evaporator or at a refrigerant suction side of a compressor becomes in a predetermined range. Accordingly, the ejector cycle has an improved nozzle efficiency and an improved ejector efficiency in a wide load variation range of the ejector cycle.
