Abstract

This study investigates the possibility of using waste heat from the car engine cooling system to drive an absorption refrigeration system by using four different refrigerant solutions (water - lithium bromide/ammonia - water/ammonia - sodium thiocyanate/acetone - Zinc bromide). Four mathematical models had been built (model for each solution) to simulate the performance of the system and to compare the performance of different solutions. Engineering Equations Solution (EES) program had been used to perform this simulation. The results were as follows: Using refrigerant solution (water - lithium bromide) at the conditions of no load on the engine can produce (14kW) cooling capacity at evaporator temperature (14C°). While for the conditions of loaded engine it produced (32kW) cooling capacity at evaporator temperature (17C°). Using refrigerant solution (ammonia - water) at the conditions of no load on the engine can produce (12kW) cooling capacity at evaporator temperature (15C°). While for the conditions of loaded engine it produced (27kW) cooling capacity at evaporator temperature (17C°). Using refrigerant solution (ammonia- sodium thiocyanate) at the conditions of no load on the engine can produce (11kW) cooling capacity at evaporator temperature (15C°). While for the conditions of loaded engine it produced (23kW) cooling capacity at evaporator temperature (17C°). Using refrigerant solution (acetone - zinc bromide) at the conditions of no load on the engine can produce (13kW) cooling capacity at evaporator temperature (16C°). While for the conditions of loaded engine it produced (32kW) cooling capacity at evaporator temperature (17C°).
