Performance Analysis of VARS Using Exhaust Gas Heat of C.I Engine
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 1
Abstract
In this paper the waste heat from C. I engine is suggested as one of the alternative energy source for refrigeration system. In this study, an overview of utilization of waste heat with a brief literature of the current related research is studied. The review covers the vapour absorption refrigeration system connected to the four stroke diesel engine. From the engine the two main areas through which the heat exhausted into the atmosphere are the cooling water and the exhaust gases. The heat available at exhaust gas is 5.5 KW and heat carried by cooling water is 12.54 KW.Vapour absorption refrigeration system is presented as an attractive substance that utilizes the waste heat from C. I engine. For the present investigation, a vapour absorption system associated with waste heat recovery from four stroke diesel engine is used to find out the coefficient of performance and energy Consumption. By using waste heat energy the coefficient of performance is increased to 23% and the energy consumption of 220 KJ/K is saved than the existing system. So it is estimated that recovery of waste heat reduces heat loss, improves performance of the system, saves the fuel, reduces the emission of exhaust gas, and is economically feasible. Also the area from which heat is lost to the surroundings decreases. From the experimental study, the vapour absorption refrigeration system can be obtained using heat that is expelled in to the atmosphere from C. I. engine. Through the study and by analyzing the obtained results it is evident that the waste heat based refrigeration system is economic, eco friendly with zero co2 emissions. Hence the system selected is technically proven, echo friendly and economically better.
