Type of article: Article

Summary

DESCRIBES AN INVESTIGATION TO QUANTIFY THE EFFECT OF IMPROPER REFRIGERANT CHARGE ON THE STEADY-STATE AND SEASONAL PERFORMANCE OF A RESIDENTIAL SPLIT-SYSTEM AIR CONDITIONER. A LITERATURE REVIEW WAS CONDUCTED, AN EXPERIMENTAL SET-UP CONSTRUCTED AND DATA WERE COLLECTED AND ANALYSED. A 10.6 KILOWATT CAPACITY SPLIT-SYSTEM AIR CONDITIONER WITH CAPILLARY TUBE EXPANSION WAS USED IN THE EXPERIMENTS. THE CHARGE IN THE SYSTEM WAS VARIED SYSTEMATICALLY TO DETERMINE ITS EFFECT ON SYSTEM VARIABLES SUCH AS CAPACITY, POWER CONSUMPTION, COP AND SEASONAL COP. FINDS THAT UNDERCHARGING BY AS LITTLE AS 5% CAN CAUSE AS MUCH AS A 6.1% DROP IN SEASONAL COP. (INT. BUILD. SERV. ABSTR., GB., 25, N 6, 1990/11-12, 90-01748.
