Performance Analysis of a Solar-powered Ejector Airconditioning Cycle with Heavier Hydrocarbons as Refrigerants

Abstract

In this paper the overall performance of the solar-powered ejector air-conditioning system, using pentane (R601) and hexane (R602) as a refrigerants, is presented. The modeling process and the efficiency of solar vapor generator (SVG) were shown. The effects of condenser and generator temperatures were examined. Simulation results indicated that condensing temperature had a strong influence on the ejector's performance. Maximum overall systems' value of COP, obtained for refrigerants R601 and R602, were 0.1 and 0.5, respectively, at Te=12°C, Tc=30°C, and G=800 W·m-2. Generator temperatures were 100-190°C for pentane and 100-200°C for hexane.
