Type of article: Article

Summary

THE ENERGY PERFORMANCE OF2 RESIDENTIAL EXHAUST-AIR HEAT PUMPS WITH DIFFERENT CONDENSER DESIGNS WAS STUDIED EXPERIMENTALLY IN A LABORATORY WITH A FOCUS ON TRANSIENT HEAT-PUMP PERFORMANCE ASSOCIATED WITH TIME VARYING REQUIREMENTS FOR WATER AND SPACE HEATING. BASEDON THE DATA, FOR A WIDE RANGE OF OPERATING CONDITIONS, THE AUTHORS DERIVED LINEAR CORRELATIONS BETWEEN THE HEAT-PUMP TIME-AVERAGE COP AND APPROPRIATE SPATIAL AND TEMPORAL AVERAGE TEMPERATURES IN THE HOT-WATER TANKS. THEY PROPOSE A NEW CONTROL SYSTEM THAT USUALLY PLACES PRIORITY ON SPACE HEATING AND, THUS, TAKES BETTER ADVANTAGE OF THE CAPACITY TO STORE HEAT IN THE WATER TANK.
