CFD Analysis on a Plate Type Heat Exchanger for Waste Heat Recovery: An Attempt to Conserve Energy for Vapour Absorption Refrigeration System through Waste Heat from IC Engines

In the commercial vapour absorption refrigeration system a heating coil generator system is usually employed to vaporize the ammonia refrigerant. In this book work, the theoretical investigations were presented by replacing the heating coil generator system with the frame plate type heat exchanger. By the way, the exhaust gases from the IC engine have been utilized to vaporize the ammonia refrigerant. The available heat in the exhaust gases was estimated based on actual IC Engine driving cycles. The frame plate type heat exchanger has been modeled and flow analysis inside the heat exchanger was conducted with the help of CFD packages. In addition, the recoverable energy of the exhaust gases was analyzed for the representative IC Engine.
