Abstract
In present scenario world facing severe energy crisis. We all think that all the energy is decreasing day by day but it is not the case, day by day the quality of the energy decreasing by each conversion process from one form to another form. So here concentration is to minimize the loss of quality of energy. Nowadays many people using HVAC systems throughout the world, so it is one of the major energy consuming industry. So it is our responsibility to minimize the loss of quality of energy in these systems This project focus on the heat pump systems and aim is to conduct exergy analysis throughout the heat pump system and to find out irreversibilities associated with each component in the system by various modifications and configurations that decreases the irreversibilities by varying parameters like type of refrigerant, source temperatures, materials associated with the model and the simulations associated with the parameters as discussed above are performed on simulation software like MAT LAB. This paper describes an exergetic analysis on a vapor compression refrigerating system. The exergetic relations have been defined. A mathematical model for carrying out exergy analysis by computer has been developed. An experiment and an exergy analysis on refrigerator using R134a, R12, R22 and R717 have been carried out to illustrate the various exergy losses occurring in the different components, and to display the potential improvements in both heating and cooling mode of vapour compression refrigeration system.
