An Exergy Analysis and Effect of Condenser and Evaporator Temperature on Ice Production Plant

Abstract

In this study, an exergy analysis of an ice production plant was carried out. The exergy formulas were written and solved based on actual plant data to point out the thermodynamics inutility. For the analysis, the necessary data are obtained from an ice production plant situated at GIDC Navsari, Gujarat, India. The plant included ammonia refrigerant vapor compression refrigeration system having 24 tonnes of ice manufacturing capacity per day, including Kirloskar-4 cylinder reciprocating compressor, shell and tube condenser, induced draft counter flow cooling tower with fill- and flooded-type evaporator. Here the effect of condenser and evaporator temperature on exergy efficiency of components, compressor work and on COP, was also discussed. It is found that the significant amount of exergy drop is happened in compressor out of numerous parts of the ice plant, and it depends on evaporating temperature, condensing temperature, and geographical conditions. To measure the exergy loss (irreversibility) of the ice production procedure, an effort was also formed. So, to get the knowledge about the potential location for the plant execution refinement, an important detail can be obtained with the help of the exergetic study and its subsidiary derivatives.
