Air conditioning system development - ejector hybrid

A paper from the Ted Perry Award winner

The idea of using solar energy for air conditioning (AC) is conceptually an attractive one for reducing peak electrical demand and CO2 emissions related to electricity generation for operating compressors. In practice the systems proposed are hampered by high cost and, due to the inconsistency of solar energy availability, the annual primary energy reduction can be less favourable. This paper introduces the background motivation of an ongoing PhD research project aimed at developing an ejector hybrid system that can help to address some of these issues. The theoretical solar COP for the system is predicted in the range of 0.1-0.12 for a moderate climate but has operational benefits over the traditional ejector cycle
