Abstract

The invention discloses an air conditioner and a low-voltage protection control device and method for a compressor in the air conditioner. The control method includes the following steps: detecting the operating current of the air conditioner to obtain a first current detection value; detecting the input voltage of the air conditioner to obtain the voltage detection value; if the first current detection value is greater than or equal to the first preset current value and the voltage detection value is continuously less than the preset voltage value within the first preset time, the compressor is controlled to stop for low-voltage overcurrent protection, In this way, the vibration of the compressor pipeline caused by low-pressure operation can be prevented from increasing, thereby preventing the occurrence of pipeline vibration cracks and refrigerant leakage, effectively protecting the compressor, improving the reliability of the compressor, and prolonging the service life of the compressor. It also prevents the compressor from starting and stopping frequently due to low voltage.

Description

technical field [0001] The invention relates to the technical field of household air conditioners, in particular to a low-pressure protection control method for a compressor in an air conditioner, a low-voltage protection control device for a compressor in an air conditioner, and an air conditioner with the control device. Background technique [0002] In the related art, the air conditioner usually protects the compressor by detecting the current value. However, the disadvantage of the related technology is that the cause of the compression overcurrent cannot be effectively judged, and there is no pertinence. [0003] Therefore, related technologies need to be improved. Contents of the invention [0004] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, an object of the present invention is to provide a low voltage protection control method for a compressor in an air conditioner, which can prote...
