Abstract

The analysis of biogas operated Ammonia-Water vapor compression absorption (hybrid) refrigeration system was carried out based on computational model being developed and the thermodynamic properties of working fluids have been used from the computer code. The variation of performance parameters such as exergy loss, COPCOOLING, COPHEATING and Exergy efficiency are studied with varying generator temperature, evaporator temperature, condenser and absorber temperature. The results indicate that maximum COP cooling as well COP heating value are found to be at generator temperature of 80 oC for the same variation in the generator temperature from 80 oC
–135 oC. The effect of the varying cooling capacity on the exergy loss in different components as well as exergy efficiency is also studied in the analysis of the hybrid system which revealed the maximum exergy loss is found in the generator which goes on increasing with an increase in the cooling capacity of the system.
