Problems solved by technology

Because the outdoor condenser and pipes are easy to freeze in low temperature environment, if not dealt with in time, it will affect the heating effect of the air conditioner. Therefore, most manufacturers use mode switching to change the air conditioner from heating mode to cooling mode. In this mode, the non-stop defrosting process is carried out. After the defrosting is completed, the air conditioner is controlled to enter the heating mode to realize the continuous replacement of defrosting and heating. However, during the defrosting process of the air conditioner, the indoor ambient temperature will fluctuate fluctuations, thereby affecting user comfort

Abstract

The invention discloses a control method of a compressor motor in an air conditioner. The control method of the compressor motor in the air conditioner comprises the following steps of acquiring a peak current of the compressor motor when the air conditioner enters into a defrost mode; calculating a maximum reactive current of the compressor motor according to the peak current of the compressor motor; controlling the compressor motor according to the maximum reactive current of the compressor motor so as to improve a calorific value of the compressor motor. According to the control method, the calorific value of the compressor motor is improved through increasing the reactive current of the compressor motor, so that the defrost time of the air conditioner is effectively shortened. The invention also discloses a control device of the compressor motor in the air conditioner, and the air conditioner.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a control method for a compressor motor in an air conditioner, a control device for a compressor motor in an air conditioner, and an air conditioner. Background technique [0002] When the outdoor ambient temperature is relatively low, the air conditioner needs to be in the heating mode for a long time to maintain the indoor ambient temperature. Because the outdoor condenser and pipeline are easy to freeze in the low temperature environment, if not dealt with in time, the heating effect of the air conditioner will be affected. Therefore, most manufacturers use the mode switching method to change the air conditioner from the heating mode to the cooling mode. After the defrosting is completed, the air conditioner is controlled to enter the heating mode to realize the continuous replacement of defrosting and heating. However, during the defrosting process of the air...
