Energy -conserving conversion double -purpose unit and refrigerating system

The utility model discloses an energy -conserving conversion double -purpose unit and refrigerating system relates to energy conversion unit field. An energy -conserving conversion double -purpose unit, includes generator, diesel engine, compressor, first clutch and second clutch, and the generator has the main shaft, and the diesel engine passes through the 2nd clutch in main shaft through a clutch in main shaft, compressor. First clutch closure and the disconnection of second clutch to the generator makes the diesel engine can drive the main shaft and rotates, so that generating electricity.Perhaps, first clutch closure and second clutch are closed to make the diesel engine can drive the main shaft and rotate, and drive compressor work, can generate electricity simultaneously. Perhaps,disconnection of first clutch and second clutch are closed, and the generator can and drive compressor work through external power supply driving spindle. A refrigerating system which has adopted foretell energy -conserving co
