REFRIGERATION MACHINE OR HEAT PUMP

摘要

The cooling machine or heat pump has a thermoacoustic work system having a heat source and a heat sink coupled with at least one thermoacoustic drive system of like construction. The heat source of the drive system has a higher temperature than the heat source of the work system. The machine can be used in a refrigerating system with heat energy removed from a cold chamber and used as a heat source in the thermoacoustic work system. The machine can also be used in a heat pump heating system with heat energy removed by way of a first heat exchange surface from a burner and used as a heat source in the thermoacoustic drive system. A process water circuit is used as a heat sink for the thermoacoustic drive system while a heating-water circuit is used as a heat sink for the thermoacoustic work system.
