EFFICIENT HEAT PUMP SYSTEMS FOR SERVICE HOT WATER.

Author(s) : ADNOT J., RABL A.

Summary

STATES THAT A REVIEW OF MEASURED PERFORMANCE OF HEAT PUMP WATER HEATERS SHOWS THAT THE AVERAGE ANNUAL COP (AROUND 3 AT BEST) IS FAR BELOW THE THEORETICAL LIMIT (AROUND 20). PROPOSES 2 SYSTEM DESIGN ALTERNATIVES TO LOWER THE TEMPERATURE RANGE OF THE HEAT PUMP. THE FIRST, APPLICABLE TO LARGE BUILDINGS, REPLACES THE CONVENTIONAL DISTRIBUTION LOOP BY TRACE-HEATED ONE-WAY PIPES. THE TEMPERATURE IS REDUCED FROM 60 DEG C TO THE END USE OF 45 DEG C. THE SECOND ALTERNATIVE MODIFIES THE INTERFACE OF THE HEAT PUMP AND TANK FOR EXAMPLE BY PLACING THE CONDENSER AT THE BOTTOM OF THE TANK TO OPTIMIZE THE CONDENSER TEMPERATURE.
