First and Second Law Analysis of a Solar Operated Ejector Absorption Refrigeration System

摘要

This analysis for the first and second law of a solar operated ejector absorption refrigeration system using duratherm 600 oil as the heat transfer fluid is performed. The proposed cycle is an integration of ejector in the absorption refrigeration cycles which could produce refrigeration output with independent of pressure of the condenser so amount of refrigerant vaporized increased. Both exergy destruction and losses in each component and hence in the overall system are determined. The effects of some influenced parameters like; generator temperature and the evaporator temperature have been observed on first and second law performance. Analysis clearly shows that performance evaluation based on first law analysis is inadequate and hence more meaningful evaluation must include second law analysis.
