    摘要： The disclosure discloses an air-conditioning system. The air-conditioning system includes a double-cylinder capacity-variable compressor (30), the double-cylinder capacity-variable compressor (30) having a suction port of an upper cylinder, a suction port of a lower cylinder and an exhaust port. The air-conditioning system further includes a first solenoid valve (71), one end of the first solenoid valve (71) is connected to the exhaust port of the double-cylinder capacity-variable compressor (30), and the other end of the first solenoid valve (71) is connected to a one-way valve (50) and the suction port of the lower cylinder of the double-cylinder capacity-variable compressor respectively. One end of the one-way valve (50) is connected to the first solenoid valve (71), and the other end of the one-way valve (50) is communicated with an inner chamber of a gas-liquid separator. The air-conditioning system further includes a second solenoid valve (72), the second solenoid valve (72) being provided in a pipeline connecting the suction port of the lower cylinder of the double-cylinder capacity-variable compressor to an inlet of the gas-liquid separator. By means of a drain bypass pipeline provided with a solenoid valve and additionally provided between the suction port of the lower cylinder and the inlet of the gas-liquid separator, a high-pressure coolant at a suction side of the lower cylinder can be decompressed to the gas-liquid separator, thereby optimizing the stability of the system when being switched from a single-cylinder operation to a double-cylinder operation. The disclosure also discloses a method for controlling an air-conditioning system.

    摘要： The present invention provides a capacity-control refrigeration cycle device capable of efficiently vary capacity, and in any of a full operation mode in which capacity of the refrigeration cycle device is not controlled and an operation mode in which the capacity is controlled, all of refrigerants are discharged into a hermetic container 1 and then, the refrigerants pass through a discharge path 11 and are guided to outside of the hermetic container 1. After a refrigerant and oil are sufficiently separated in the hermetic container 1, the refrigerant is discharged to outside of the hermetic container 1. Therefore, efficiencies of a condenser 300 and an evaporator 600 are not deteriorated. Since it is possible to reduce an amount of oil taken outside of the hermetic container, it is possible to stably secure oil in an oil reservoir 22, and to prevent bite of parts of a compressing mechanism and to prevent abnormal wearing.

    摘要： A refrigeration system includes a compressor. A heat rejection heat exchanger is downstream of the compressor along a refrigerant primary flowpath. An expansion device is downstream of the heat rejection heat exchanger along the primary flowpath. A heat absorption heat exchanger is downstream of the expansion device along the primary flowpath. An economizer heat exchanger is between the heat rejection heat exchanger and the expansion device along the primary flowpath. The economizer heat exchanger includes a first portion configured to provide heat transfer from the primary flowpath to a first economizer flowpath. The economizer heat exchanger includes a second portion configured to provide heat transfer from the primary flowpath to a second economizer flowpath.
