Abstract

The invention provides an air conditioner control system and air conditioner using an ejector, wherein the system includes: a compressor, a gas-liquid separator, a first heat exchanger, an ejector and an opening and closing device; the opening and closing device is connected to the ejector between the outlet of the heat exchanger and the liquid pipe of the first heat exchanger; the air pipe of the first heat exchanger and the suction port of the compressor are respectively connected with the inlet and outlet of the gas-liquid separator; the exhaust port of the compressor is connected with the ejector The first inlet of the gas-liquid separator is connected to the second inlet of the ejector; after the air conditioning system is started, the opening and closing device is opened, and the high-pressure gas discharged from the compressor flows to the ejector to drive the gas-liquid separator The liquid refrigerant in the middle flows to the ejector and mixes with the high-pressure gas to form a mixed refrigerant. After the mixed refrigerant flows into the first heat exchanger, the liquid refrigerant in the first heat exchanger is converted into a gaseous refrigerant. The gaseous refrigerant will not cause liquid shock to the compressor; prevent the compressor from running oil, and will not cause the compressor to be short of oil or oil-free, ensuring the reliability of the compressor.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner control system using an ejector and an air conditioner. Background technique [0002] During the use of the air conditioner, if the air conditioner is left standing for a long time, the refrigerant will be deposited inside the gas-liquid separator and the outdoor heat exchanger; Under the push of pressure, the refrigerant will enter the gas-liquid separator through the inlet of the outdoor heat exchanger and the gas-liquid separator, so that the refrigerant in the outdoor heat exchanger and the refrigerant in the gas-liquid separator enter the compressor together. middle. As a result, the refrigerant will cause the problem of liquid hammer in the compressor; and when the temperature at the bottom of the compressor is higher than the saturation temperature of the refrigerant in the oil tank of the compressor, the refrigerant entering the compressor wil...
