FIELD TEST OF A NOVEL BIVALENT HEAT PUMP TO ESTABLISH HEATING DEMAND AND LOAD PROFILES.

Author(s) : CUTHBERT D. F.

Summary

A NOVEL BIVALENT HEATING APPLIANCE WAS INSTALLED IN A TORONTO-AREA HOME. THE UNIT IS AN AIR-SOURCE SPLIT-SYSTEM HEAT PUMP, WHICH INCORPORATES ITS OWN AUXILIARY HEAT SOURCE IN THE FORM OF A GAS BURNER LOCATED BENEATH THE OUTDOOR COIL OF THE UNIT. AT WARMER TEMPERATURES, THE MACHINE RUNS AS A NORMAL AIR-SOURCE HEAT PUMP, BUT AT COLDER TEMPERATURES, THE GAS BURNER IS ACTIVATED FOR < SECOND-STAGE > HEATING AND DEFROSTING. DURING THIS UNUSUAL GAS BURNING OPERATION, FLUE GASES ARE CONDENSED ON THE OUTDOOR HEAT EXCHANGER TO ACHIEVE COMBUSTION EFFICIENCIES SIMILAR TO THOSE OF A CONDENSING GAS FURNACE.
