Abstract

The invention relates to the technical field of intelligent household appliances, and discloses a method for reducing air conditioner refrigerant noise, an air conditioner comprises an auxiliary gas-liquid separator, a plate heat exchanger and an auxiliary electronic expansion valve, the auxiliary gas-liquid separator is used for separating a refrigerant flowing out of an outdoor heat exchanger and throttled into a gas state and a liquid state, and the plate heat exchanger and the auxiliary electronic expansion valve are used for secondary supercooling. A main flow path of the plate heat exchanger feeds a liquid refrigerant into an indoor unit, an auxiliary flow path feeds a gaseous refrigerant throttled by an auxiliary electronic expansion valve into an outdoor unit, and the method comprises the steps that the outdoor environment temperature is detected; and under the condition that the outdoor environment temperature is larger than or equal to the temperature threshold value, the opening degree of the auxiliary electronic expansion valve is adjusted. The gaseous refrigerant enters the outdoor unit through the auxiliary flow path of the plate heat exchanger, so that the gaseous refrigerant fed into the indoor unit by the plate heat exchanger is reduced, and the flowing noise of the gaseous refrigerant in the indoor unit during secondary supercooling of the air conditioner is reduced. The invention further discloses a device for reducing the air conditioner refrigerant noise, an air conditioner and a storage medium.

Description

technical field [0001] The present application relates to the technical field of smart home appliances, for example, to a method and device for reducing noise of an air conditioner refrigerant, an air conditioner, and a storage medium. Background technique [0002] At present, when the air conditioner is running, cooling and heating are realized through the refrigerant in the heat exchanger. When the refrigerant flows in the indoor unit, it will generate noise, which affects the user experience. [0003] The method of reducing the noise of the air conditioner refrigerant in the prior art is: when the air conditioner is in the quiet mode, the inverter compressor of the air conditioner is controlled to start at the first frequency; after the first preset time, the inverter compressor is controlled at the first preset rate The frequency of the compressor is increased; judge whether the current frequency of the variable frequency compressor reaches the frequency corresponding t...
