A SIMPLIFIED CHART USED TO PREDICT THE UTILIZATION OF HEAT PUMP SYSTEM

Abstract

The present work gives a simple chart that helps the designer to make a quick estimation and decision if the heat pump system is feasible or not compared with traditional system and the economic limitation for use this type of systems by defining the annual ratio of cooling load to the heating load (R), the ratio of annually operating hours (C), Boiler efficiency ( ) and coefficient of performance of chillers (COP). The results showed ability to use heat pump systems within a certain limit of annually cooling to heating load ratio to produce energy saving within certain value of other factors.
