Comprehensive Utilization of System Energy
 
Improvement of the energy efficiency of the entire refrigeration sys-tem is crucial for large frozen food processing plants in order to reduce energy consumption and increase enterprise efficiency, so refrigerator manufacturers, for instance Yantai Moon, have developed integrated systems consisting of an ammonia/ carbon dioxide cascade refrigeration system, an ammonia high-temperature heat pump, and an R245fa vapor- compression heat pump. The integrated system can produce chilled water, hot water, and vapor simultaneously and increase primary energy efficiency through pipe connection, and thus realizes the waste heat recycling and can replace a coal boiler or other high-polluting vapor production equipment.
