In the present embodiment, when the winding temperature of current compressor is less than default heating temperature, illustrate compressor lubricant oil
Temperature it is equally lower, it may occur however that the case where causing compressor not start normally since viscosity is excessive, need at this time
Subzero oil is heated to start to avoid compressor and is failed, that is, exports a heated current to compressor winding, makes to compress
Machine heating in winding in the process, is still persistently detected and is calculated current by compressor heating in winding indirect heating lubricating oil
The winding temperature of compressor specially detects the voltage of current compressor terminal, according to the heated current and current compressor
The voltage of terminal calculates the winding resistance value of current compressor, similarly, according to the winding temperature of real-time current compressor, in conjunction with
Normal temperature and the factory real-time winding temperature of computing the resistor value stop output heating electricity when winding temperature is greater than target temperature
