Abstract

The invention provides an air conditioner control system using an ejector and an air conditioner. The system comprises a compressor, a gas-liquid separator, a first heat exchanger, the ejector and a starting / closing device; the starting / closing device is connected between an outlet of the ejector and a liquid pipe of the first heat exchanger; a gas pipe of the first heat exchanger and a gas sucking port of the compressor are respectively connected with an inlet and an outlet of the gas-liquid separator; an exhaust port of the compressor is connected with a first inlet of the ejector; a bottom port of the gas-liquid separator is connected with a second inlet of the ejector; after the air conditioning system is started, the starting / closing device is opened; high-pressure gas exhausted from the compressor flows to the ejector to drive a liquid-state refrigerant in the gas-liquid separator to flow to the ejector for mixing with high-pressure gas to form a mixed refrigerant; and the mixed refrigerant flows into the first heat exchanger to convert as a gas-state refrigerant with the liquid-state refrigerant in the first heat exchanger. The gas-state refrigerant cannot hydraulically shock the compressor to prevent the oil overflowing phenomenon of the compressor without generating oil shortage and no oil of the compressor, so that the reliability of the compressor is guaranteed.

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...
