EVALUATION OF DUAL SOURCE EVAPORATOR FOR RESIDENTIAL HEAT PUMPS.

Author(s) : REISTAD G. M., GRIFFITHS J. G., LANG S.

Summary

A STUDY OF A DUAL SOURCE, AIR AND DOMESTIC WATER, HEAT PUMP FOR RESIDENTIAL USE HAS BEEN CONDUCTED. THE DUAL SOURCE HEAT PUMP INCORPORATES A SINGLE EVAPORATOR THAT HAS PASSAGEWAYS FOR AIR, REFRIGERANT AND WATER. THE EVAPORATOR OPERATES AS AN AIR OR A WATER HEAT EXCHANGER DEPENDING ON THE PREVAILING AMBIENT AIR TEMPERATURE. RESULTS SHOW THAT THE UNIT SIZE REQUIRED FOR A RESIDENCE IS REDUCED. THE ENERGY CONSUMPTION IS LOWERED AND PEAKING LOADS ARE SMALLER. THESE RESULTS CAN BE ACHIEVED WITH A UNIT THAT IS QUITE COMPARABLE IN FIRST COST WITH SIMILARLY SIZED AIR SOURCE UNITS.
