摘要： The opening control of a pressure reducing expansion valve 40 is performed only when the refrigerant pressure on the high-pressure side in an outdoor unit 10 is high during a cooling operation. The opening of the valve 40 is determined on the basis of the driving frequency of a compressor 16 at that point in time, i.e., the volumetric flow rate of a refrigerant. A pressure reduction in the valve 40 is suppressed when the volumetric flow rate of the refrigerant is large and a pressure loss in a communication pipe 30 is large, and the pressure reduction in the valve 40 is increased when the volumetric flow rate of the refrigerant is small and a pressure loss in a communication pipe 30 is small, whereby the amount of pressure reduction of the refrigerant is adjusted in the total refrigerant circuit from the compressor 16 to an indoor expansion valve 22.

摘要： An air-conditioning apparatus includes an injection pipe allowing a part of a refrigerant, as discharged from a compressing device, to flow into an intermediate portion of a compression stroke of the compressing device, and an injection internal heat exchanger that exchanges heat between a refrigerant stream that flows through the injection pipe and a refrigerant stream that flows into a heat-source-side heat exchanger after passing through an indoor unit.

摘要： In certain embodiments, a transcritical refrigeration system (101) provides refrigeration by circulating refrigerant through the system (101). The system (101) includes a gas cooler (130), a heat exchanger (210), a high pressure expansion valve (135), a flash tank (105), refrigeration cases (115), and compressors (120). The gas cooler (130) cools the refrigerant to a first temperature. The heat exchanger (210) cools the refrigerant flowing from the gas cooler (130) to the high pressure expansion valve (135) to a second temperature. The high pressure expansion valve (135) is coupled to the flash tank (105), which is coupled to the refrigeration cases (115). The refrigeration cases (115) are coupled to the compressors (120), which are coupled to the gas cooler (130). An expansion valve (110) between the gas cooler (130) and the heat exchanger (210) may cool the refrigerant flowing to the heat exchanger (210). A high pressure vapor compressor (215) between the heat exchanger (210) and the gas cooler (130) may compress the refrigerant flowing from the heat exchanger (210) to the gas cooler (130).

摘要： A refrigeration cycle device includes a refrigeration cycle formed by connecting compressor (2), condenser (3), expansion valve (4) and evaporator (5) to each other. As a refrigerant in the refrigeration cycle, a working fluid containing 1,1,2-trifluoroethylene (R1123) and difluoromethane (R32) is used. A degree of opening of expansion valve (4) is controlled such that the refrigerant has two phases at a suction portion of compressor (2). With such a configuration, it is possible to provide highly reliable refrigeration cycle device (1) by suppressing occurrence of a disproportionation reaction of R1123.
