Abstract

The invention provides a compressor winding heating control method and device. The method comprises the following steps: the exhaust temperature of a compressor is obtained; and the heating current ofcompressor windings is adjusted according to the exhaust temperature. Through heating of the compressor windings, heat of refrigerants is absorbed to transfer to an indoor unit evaporator through thewindings, so that the low-temperature heating capacity is improved.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a method and device for controlling heating of compressor windings. Background technique [0002] Low-temperature heating has always been a technical difficulty of the inverter air-conditioning system, including the technology of painting the enthalpy-increasing variable-frequency compressor and the technology of two-stage compression variable-frequency compressor to solve the problem of low-temperature heating. [0003] At present, in the case of not using a specially designed compressor, in order to increase the low-temperature heating capacity, it can only be achieved by increasing the compressor speed. However, there is an upper limit to the operating speed of the compressor, and if the speed is too high, it will cause the mechanical wear of the compressor and cause it to fail. Contents of the invention [0004] The present invention aims at solving one of the technica...
