LABORATORY TESTS OF A RESIDENTIAL LOW TEMPERATURE WATER SOURCE HEAT PUMP.

Author(s) : MEI V. C.

Summary

A RESIDENTIAL UNITARY LOW TEMPERATURE WATER-SOURCE HEAT PUMP WAS TESTED IN THE LABORATORY. THE HEAT PUMP CAPACITY AND COP WERE FOUND TO BE LINEARLY RELATED TO THE SOURCE-WATER TEMPERATURES. IN THE HEATING MODE, THE CAPACITY AND COP INCREASED WITH INCREASING SOURCE-WATER TEMPERATURE AND FLOW RATE. IN THE COOLING MODE, THE CAPACITY AND COP DECREASED WITH INCREASING SOURCE-WATER TEMPERATURE BUT INCREASED WITH INCREASING WATER-FLOW RATE. FOR CYCLIC OPERATION OVER THE TESTED SOURCE-WATER TEMPERATURE RANGE, 280 TO 294.6 K (7 TO 21.6 DEG C), THE COEFFICIENT OF DEGRADATION RANGED FROM 0.196 TO 0.137 FOR HEATING AND FROM 0.131 TO 0.161 FOR COOLING. THE EFFECT OF INLET AIR HUMIDITY WAS ALSO STUDIED FOR COOLING MODE OPERATION. A SAMPLE CALCULATION DEMONSTRATES THE APPLICATION OF THE TEST RESULTS IN CALCULATING THE ANNUAL PERFORMANCE FACTOR.
