When, most of refrigerant can rest in compressor.Therefore, air conditioner does not have to for a long time, rests on the refrigerant in compressor
It will appear layering with refrigeration oil, refrigerant is sunken to compression motor spindle since density is larger, and refrigeration oil floats on system since density is smaller
Cryogen, special gas temperature become apparent from when relatively low.If at this point, starting compressor, there is refrigeration oil and is pulled out compressor,
It gets in machine and piping.The refrigeration oil got in machine or piping can not also return in compressor in time, in turn result in
Compressor is damaged because of oil starvation.
In the related technology, in order to avoid refrigeration oil is brought away from compressor, the exhaust outlet for being typically employed in compressor adds oil
The oil return bypass of liquid/gas separator and capillary composition, the freezing oil that will be carried from the refrigerant that the exhaust outlet of compressor is discharged
From rear, the refrigeration oil separated is sent back to by capillary in compressor, but oil-liquid separator cost is added in actually generating
It is higher, meanwhile, the refrigeration oil isolated can not be made to be returning momentarily in compressor using which, can only run up to it is certain
Slowly infiltration returns in compressor after amount.
Therefore, a kind of starting of air conditioner control method of offer of the embodiment of the present invention and air conditioner, to improve the above problem.
