Integration of an Ammonia-water Absorption Refrigeration System with a Marine Diesel Engine: A Thermodynamic Study

This paper examines through a thermodynamic analysis the feasibility of using waste heat from marine Diesel engines to drive an ammonia-water absorption refrigeration system. An energy balance of a diesel engine shows that sufficient waste heat is provided. The results illustrate that higher performance of the system is obtained at high generator and evaporator temperatures and also at low condenser and absorber temperatures.
