This paper examines through a thermodynamic analysis the feasibility of using waste heat from marine Diesel engines to drive a vapor compression refrigeration system. Several working fluids including propane, butane, isobutane and propylene are considered. Results showed that isobutane and Butane yield the highest performance, whereas propane and propylene yield negligible improvement compared to R134a for operating conditions considered.

The Impact

In this paper, for the purpose of providing a scientific reference for saving energy and improving the efficiency of diesel engine, the impact of ethanol diesel-oil alternative fuel and waste heat recovery are investigated on the basis of thermodynamic analysis. The results illustrate that, after using ethanol diesel alternative fuel, engine performance parameters are of no big change, however, the exhaust emissions are significantly reduced; Recycling the energy contained in the exhaust gas and cooling water, can achieve the purpose of energy conservation and emissions reduction, beside improving the thermal efficiency and exergy efficiency of the diesel engine.
