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 freq

Example Embodiment

[0037] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following will further describe the present invention in detail with reference to the accompanying drawings and embodiments.

[0038] See figure 1 , The figure shows a flow chart of an embodiment of the method for controlling the compressor of an air conditioner based on the degree of cold and heat of the present invention. Specifically, it is the flow of the compressor control method of an embodiment that takes into account the comfort of indoor personnel and the operating efficiency of the compressor Figure.

[0039] Such as figure 1 As shown, the method for realizing air-conditioning compressor control in this embodiment includes a winding switching control process formed by the following steps:

[0040] Step 101: Determine the real-time heat and coldness of indoor personnel and compare with the set heat and coldness level.

[0041] Among them, the determination of the r...

Abstract

The invention discloses a method and device for controlling an air conditioner compressor based on the cold and heat degree, and an air conditioner. The method comprises the steps that the following winding switching control process is circularly executed, specifically, the real-time cold and heat degree of indoor personnel is determined and compared with the set cold and heat degree level; if thereal-time cold and heat degree belongs to the uncomfortable cold and heat degree level, a winding of the compressor is controlled to be in a triangular connection mode; and if the real-time cold andheat degree belongs to the comfortable cold and heat degree level, the winding of the compressor is controlled to be in a star-shaped connection mode. By applying the method and device and the air conditioner, the overall operation performance of the air conditioner can be improved.

Description

Technical field [0001] The present invention belongs to the technical field of air conditioning. Specifically, it relates to an air conditioner and its control, and more particularly, to a method, a device and an air conditioner for controlling an air conditioner compressor based on the degree of coldness and heat. Background technique [0002] The existing variable frequency air conditioner has the advantages of 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 in the internal winding connections. When the compressor runs at the same frequency, the compressor efficiency corresponding to different winding connections is not completely the same. At present, the winding connection mode of most air-conditioning compressors has been determined after leaving the factory, and cannot be changed during operati...
