Embodiment Construction

[0030] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0031] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0032] The solution of the embodiment of the present invention is mainly that the air conditioner not only includes a refrigerant circulation loop composed of a compressor with a gas-liquid separator, a four-way valve, an outdoor exchanger and an indoor heat exchanger, but also includes a flow control device. The inlet of the flow control device is connected with the four-way valve; the outlet of the flow control device is connected with the gas-liquid separator of the compressor. The flow control device controls the flow rate of the refrigerant returning from the four-way valve to prevent the returning refrigerant from accumulating in the gas-liquid separato...

Abstract

The invention discloses an air conditioner comprising a refrigerant circulation loop composed of a compressor with a gas-liquid separator, a four-way valve, an outdoor exchanger and an indoor heat exchanger. The air conditioner further comprises a flow control device. An inlet of the flow control device is connected with the four-way valve. An outlet of the flow control device is connected with the gas-liquid separator of the compressor. The invention further discloses an air conditioner control method and device and a computer readable storage medium. The situation that returned refrigerants are all gathered into the gas-liquid separator of the compressor is prevented, overflowing of the refrigerants in the gas-liquid separator to the compressor due to the excessively high liquid level of the refrigerants is avoided, and accordingly the liquid impact phenomenon of the compressor is avoided.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an air conditioner, its control method, device and computer-readable storage medium. Background technique [0002] At present, at the initial start-up of the air conditioner, the liquid refrigerant in the air conditioner will return to liquid to be stored in the gas-liquid separator that comes with the compressor. In this case, due to the high liquid level of the refrigerant in the gas-liquid separator, there is a relatively obvious liquid return situation, which may easily cause the amount of liquid refrigerant in the gas-liquid separator to exceed its maximum allowable value and overflow into the compressor, thereby Causes liquid hammer problems in the compressor. Contents of the invention [0003] The main purpose of the present invention is to provide an air conditioner and its control method, device and computer-readable storage medium, aiming to solve th...
