DESUPERHEATER WATER-HEATER AND AIR-TO-AIR HEAT PUMP SYSTEM: REPRESENTATIVE PERFORMANCE DATA.

Summary

A REFRIGERANT-TO-WATER HEAT EXCHANGER DOWNSTREAM OF THE COMPRE SSOR OF A CONVENTIONAL AIR-TO-AIR HEAT PUMP SERVES AS A DESUPERHEATER, TRANSFERS THERMAL ENERGY TO THE WATER, AND MAY PROVIDE MOST OF THE HOT WATER REQUIREMENTS IN A RESIDENTIAL APPLICATION. THE PERFORMANCE OF THE DESUPERHEATER DEPENDS ON THE OPERATING CONDITIONS AFFECTING THE RETURN WATER TEMPERATURE, THE REFRIGERANT DISCHARGE TEMPERATURES, AND THEIR FLOW RATES. TEST DATA ARE NOW PROVIDED FOR A SAMPLE CASE. THE DESUPERHEATER GENERALLY INCREASES THE EER OF THEHEAT PUMP AND DECREASES THE COP WHILE IN A HEATING MODE. THESE CHANGES CAN BE QUITE NOTABLE AND ARE DEPENDENT ON THE HEAT PUMP'S OPERATING CONDITIONS AND THE CONDITIONS OF THE WATER ENTERING THE DESUPERHEATER.
