ASSESSMENT OF A DOMESTIC HEAT PUMP. 2. COMPONENT AND FROSTING ANALYSIS.
Author(s) : COX-SMITH I. R., CARRINGTON C. G.
Type of article: Article
Summary
EXAMINES THE PERFORMANCE OF THE HEAT EXCHANGERS OF AN UNSOPHISTICATED AIR-AIR HEAT PUMP, WITH EMPHASIS ON THE EVAPORATOR FROSTING CHARACTERISTICS. THE DATA RELATE TO AN OPERATING DOMESTICHEAT PUMP IN DUNEDIN, NEW ZEALAND. FINDS THAT EVAPORATOR FROSTING REDUCES THE SEASONAL COP BY LESS THAN 1.7% IN THIS EXAMPLE BUT THE DEFROST RATE IS VERY SENSITIVE TO SMALL CHANGES IN THE EVAPORATOR CAPACITY. STATES THE FROST FORMATION GENERALLY HAS AN IMPORTANT INFLUENCE ON THE EVAPORATOR OPTIMIZATION CALCULATION. ALSO ANALYSES THE EFFECTIVENESS OF THE EXPANSION VALVE AND OF THE DEFROST THERMOSTAT. (INT. BUILD. SERV. ABSTR., GB., 25, N 2, 1990/03-04, 90-00384.
