ESTIMATION OF THE SEASONAL CYCLIC LOSSES OF AN AIR CONDITIONER.

Author(s) : BAHEL V., ZUBAIR S. M., ABDELRAHMAN M. A.

Summary

THE PAPER ILLUSTRATES THE EFFECTS OF DEGRADATION IN THE COP OF AN AIR CONDITIONER CAUSED BY CYCLIC OPERATIONS. THIS IS DEMONSTRATED BY CONSIDERING A 100 M2 RESIDENCE IN DHAHRAN EQUIPPED WITH A 17.6 KILOWATTS CENTRAL UNIT. SIMULATIONS SHOW CYCLIC LOSSES CAN BE AS HIGH AS 24% DURING THE MONTHS OF LOW COOLING WHEN SYSTEM ON-TIME IS MINIMAL ; LITTLE DEGRADATION WAS EXPERIENCED DURING THE HOT MONTHS. THE STUDY FOUND THAT ANNUAL STEADY-STATE ENERGY CONSUMPTION WAS 17,900 KILOWATTHOUR ; TRANSIENT LOSSES REQUIRED AN ADDITIONAL 2,100 KILOWATTHOUR. THE TOTAL PREDICTED VALUE OF 20,000 KILOWATTHOUR IS WITHIN 5% OF THE METERED CONSUMPTION. DEGRADATION MAY ALSO BE LOWERED BY INSTALLING AN INVERTER-DRIVEN, VARIABLE-SPEED AIR-CONDITIONING SYSTEM.
