Title:
METHOD FOR CONTROLLING HEATING BELT OF COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2021/078033
Kind Code:
A1
Abstract:
Disclosed is a method for controlling a heating belt of a compressor. The method comprises: measuring a suction pressure P of a compressor to determine a corresponding suction saturation temperature Tps; measuring an actual suction temperature Ts of the compressor and a lubricating oil temperature Toil of the compressor; and determining the opening or closing of a heating belt of the compressor on the basis of the suction saturation temperature Tps, the actual suction temperature Ts and the lubricating oil temperature Toil. According to the method, the opening or closing of the heating belt of the compressor is determined on the basis of the three temperatures and the specific relationship therebetween, such that the heating belt of the compressor can be controlled more precisely and effectively, and not only can a liquid impact phenomenon of the compressor be prevented, but the output power of the heating belt of the compressor can also be effectively reduced, thereby improving the energy efficiency ratio of the whole air-conditioning system.
