Air conditioner and its control methods, devices, electronic equipment and storage media

Abstract

The present invention proposes an air conditioner and its control method, device, electronic equipment, and storage medium, wherein the air conditioner includes at least two outdoor units, at least two indoor units, a first regulating valve arranged on a low-pressure air pipe, a set With the second regulating valve on the high-pressure air pipe and the third regulating valve on the high-pressure liquid pipe, the control method of the air conditioner includes: when the air conditioner is in the rotation defrosting mode of the outdoor unit, control the third regulating valve corresponding to the unopened indoor unit. A regulating valve is opened to the preset maximum opening degree, the corresponding second regulating valve is closed and the corresponding third regulating valve is opened to the first set opening degree; the first regulating valve corresponding to the opened indoor unit is controlled to close, and the corresponding The third regulating valve is opened and the corresponding second regulating valve is opened to a second set opening degree. This method does not need to match a special indoor unit, and does not need to upgrade the indoor unit, and can realize the rotation defrosting of the outdoor unit, which can avoid the phenomenon that the defrosting time is too long, and improves the user experience.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an air conditioner and its control method, device, electronic equipment, and storage medium. Background technique [0002] In the existing air conditioner, in the heating mode, the refrigerant absorbs heat from the outside through the outdoor heat exchanger, then increases the pressure and temperature through the compressor, and discharges the heat from the outside to the room to achieve the heating effect. But in the winter heating mode, the lower the outdoor temperature, the less heat the outdoor heat exchanger can transfer from the outdoor to the indoor, the worse the indoor heating effect will be, and the refrigerant in the outdoor heat exchanger will be It needs to absorb the heat of the outdoor air, which needs to be lower than the temperature of the outdoor air, which will cause the outdoor heat exchanger to frost in the heating mode. [0003] In order to...

Problems solved by technology

However, this method requires the indoor unit to perform actions different from the normal defrosting process in the process of rotating defrosting (referred to as round defrosting), that is, the indoor unit needs to be upgraded accordingly, or needs to cooperate with a dedicated indoor unit. For air conditioners, the indoor unit needs to match the outdoor unit. Therefore, when the manufacturer launches a new indoor unit, there will be a situation where the new indoor unit and the old indoor unit coexist for a long time. In this case, the outdoor unit When defrosting in rotation, it is impossible to make corresponding control actions on the old indoor unit, which may lead to insufficient defrosting heat of the outdoor unit, resulting in failure of defrosting or slow defrosting process, affecting user comfort and poor user experience
