ShareREFRIGERATION SYSTEM DYNAMICS DURING THE REVERSE CYCLE DEFROST.
Author(s) : O'NEAL D. L.
Summary
THE OBJECTIVE OF THE RESEARCH WAS TO CHARACTERIZE THE DYNAMIC RESPONSE OF AN AIR-SOURCE HEAT PUMP DURING THE REVERSE CYCLE DEFROST. THE TEST SETUP CONTAINED A NOMINAL 10.5 KILOWATT CAPACITY RESIDENTIAL AIR-TO-AIR HEAT PUMP THAT USED A THERMAL EXPANSION VALVE FOR EXPANSION DURING THE DEFROST. MEASUREMENTS MADE OF REFRIGERANT TEMPERATURE AND PRESSURE THROUGHOUT THE SYSTEM, REFRIGERANT FLOW RATES, AIR-SIDE CAPACITY, COMPRESSOR/OUTDOOR FAN POWER, AND REFRIGERANT LEVEL IN THE ACCUMULATOR. A DETAILED DESCRIPTION OF THE PHYSICAL PROCESSES THAT OCCUR DURING A DEFROST ARE PROVIDED.
