Air conditioner, control method and device for air conditioner, electronic equipment and storage medium

Abstract

The invention puts forward an air conditioner, a control method and device for the air conditioner, electronic equipment and a storage medium. The air conditioner comprises at least two outdoor units,at least two indoor units, a first regulation valve arranged on a low-pressure air pipe, a second regulation valve arranged on a high-pressure air pipe, and a third regulation valve arranged on a high-pressure liquid pipe. The control method for the air conditioner comprises the following steps of: when the air conditioner is under an outdoor unit rotation defrosting mode, controlling the first regulation valve corresponding to the indoor unit which is not started to a preset maximum opening degree, controlling the corresponding second regulation valve to be closed, and controlling the corresponding third regulation valve to be opened to a first set opening degree; and controlling the first regulation valve corresponding to the started indoor unit to be closed, controlling the corresponding third regulation valve to be opened, and controlling the corresponding second regulation valve to be started to a second set opening degree. According to the method, the rotation defrosting of theoutdoor unit can be realized without matching with a special indoor unit or upgrading the indoor unit, a phenomenon that defrosting time is overlong can be avoided, and a user experience degree is improved.

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
