Abstract

The invention discloses a method and device for controlling an air conditioner compressor based on the air speed of an indoor unit. The method comprises the step of circularly executing the followingwinding switching control processes: the real-time indoor unit air speed of the air conditioner indoor unit is determined and compared with a first set air speed threshold; if the real-time indoor unit air speed is not less than the first set air speed threshold, windings of the compressor are controlled to be connected in a triangle mode; and if the real-time indoor unit air speed is less than the first set air speed threshold, the windings of the compressor are controlled to be connected in a star-shape mode. By applying the method, overall operation performance of an air conditioner can beimproved.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, in particular relates to the control of an air conditioner, and more specifically relates to a method and a device for controlling the compressor of the air conditioner based on the wind speed of an internal unit. Background technique [0002] The existing frequency conversion air conditioner has the advantages of more accurate temperature control, less power consumption, and lower noise than the fixed frequency air conditioner by adjusting the operating frequency of the compressor. For compressors, there are star connection and delta connection for the internal winding connection. When the compressor runs at the same frequency, the compressor efficiency corresponding to different winding connection is not completely the same. At present, the winding connection mode of most air conditioner compressors has been determined after leaving the factory and cannot be changed during operation. U...
