Problems solved by technology

Simply controlling the switching of the winding connection mode based on the frequency of the compressor can improve the operating efficiency of the compressor, but it cannot guarantee the comfort of the indoor environment
Moreover, when switching the winding connection mode, it is generally necessary to stop the compressor first and then switch. If the frequency changes frequently and the winding connection mode is frequently switched, the compressor needs to be stopped frequently, which will greatly affect the comfort of the indoor environment. Impact
Thus, using the existing method, the effect of improving the overall performance of the air conditioner by improving the efficiency of the compressor is reduced

Abstract

The invention discloses an air conditioner operation control method and device. The air conditioner operation control method comprises the step of circularly executing the following winding switchingcontrol processes: the temperature difference between the real-time indoor temperature and an indoor temperature target value is calculated, and the real-time indoor temperature difference is obtainedand compared with a first set indoor temperature difference threshold; if the real-time indoor temperature difference is not less than the first set indoor temperature difference threshold, windingsof a compressor are controlled to be connected in a triangle mode; and if the real-time indoor temperature difference is less than the first set indoor temperature difference threshold, the windings of the compressor are controlled to be connected in a star-shape mode, and the operation rotating speed of an indoor fan is adjusted based on the real-time indoor humidity while the windings of the compressor are controlled to be connected in the star-shape mode. By applying the air conditioner operation control method, overall operation performance of an air conditioner can be improved.

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 an operation control method and a control device of the air conditioner. 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. Under certain operating frequencies, the efficien...
