Problems solved by technology
In the constant temperature dehumidification process of the three-pipe small multi-connected indoor unit, when the dehumidification temperature is set to be high, it is necessary to increase the flow rate of the auxiliary heat exchanger gaseous refrigerant to generate more heat and neutralize the cold air of the main heat exchanger to generate Hot air with a higher temperature, however, as the refrigerant flow rate of the auxiliary heat exchanger increases, the heat exchange of the heat exchanger will be insufficient, especially when the low wind speed is running, this phenomenon is more obvious
Therefore, part of the gaseous refrigerant in the auxiliary heat exchanger will enter the main channel to produce a gas-liquid two-phase refrigerant, and when the gas-liquid two-phase refrigerant in the main channel passes through the electronic expansion valve in the main channel, it will generate refrigerant noise of water flow. Seriously affect user comfort

The invention discloses an air conditioner and its control method and device. The method includes the following steps: identifying that the air conditioner needs to enter a dehumidification mode; obtaining the first temperature and the reference temperature on the auxiliary road in the air conditioner; The opening degree of the throttling element on the auxiliary road is adjusted with reference to the temperature. The control method of the present invention can reduce the refrigerant noise generated when the throttling element on the auxiliary road has a large opening while ensuring the cooling and heating effect of the air conditioner, reduce the noise of the whole machine, and improve user comfort.
Description
technical field [0001] The invention relates to the technical field of household appliances, in particular to an air conditioner control method, an air conditioner control device and an air conditioner with the control device. Background technique [0002] The three-pipe small multi-connected indoor unit includes: main heat exchanger, auxiliary heat exchanger and refrigeration components. In the constant temperature dehumidification process of the three-pipe small multi-connected indoor unit, when the dehumidification temperature is set to be high, it is necessary to increase the flow rate of the auxiliary heat exchanger gaseous refrigerant to generate more heat and neutralize the cold air of the main heat exchanger to generate The hot air with a higher temperature, however, as the refrigerant flow rate of the auxiliary heat exchanger increases, the heat exchange of the heat exchanger will be insufficient, especially when the fan is running at a low wind speed, this phenomen...
