COMPRESSOR PROTECTIVE METHOD AND STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2003/104656
Kind Code:
A1
Abstract:
A method and device, for protecting a compressor. When the temperature of a compressor having an electromagnetic clutch is equal to or below a preset predetermined value during the stop of the compressor, electricity is supplied to a core of the electromagnetic clutch so that the core functions as a heater to raise the temperature of the compressor above the predetermined temperature. Protection of the compressor is achieved with a simple structure and low costs because there is no need to provide a dedicated heater for raising the temperature of the compressor.
