Title:
AIR-CONDITIONING SYSTEM AND METHOD FOR CONTROLLING SAME
Document Type and Number:
WIPO Patent Application WO/2015/096539
Kind Code:
A1
Abstract:
An air-conditioning system comprises a double-cylinder capacity-variable compressor (30) with an upper cylinder air suction port, a lower cylinder air suction port and an exhaust port. The air-conditioning system further comprises 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 separately connected to a one-way valve (50) and the lower cylinder air suction port of the double-cylinder capacity-variable compressor. 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 connected to the inner chamber of a gas-liquid separator. The air-conditioning system further comprises a second solenoid valve (72) arranged in a pipeline connecting the lower cylinder air suction port of the double-cylinder capacity-variable compressor to the inlet of the gas-liquid separator. By means of the drain bypass pipeline provided with the solenoid valve and additionally arranged between the lower cylinder air suction port and the inlet of the gas-liquid separator, the high-pressure refrigerant at the lower cylinder air suction side is discharged to the gas-liquid separator, so that the stability of the system when being switched from single-cylinder operation to double-cylinder operation is improved. Also disclosed is a method for controlling the air-conditioning system.
