Abstract

Fin tube heat exchangers are used in many heating and cooling devices for the purpose of heat transfer from one element to other by conduction and convection. Due to their designs fin tube heat exchangers also provide a control space or volume for carrying out chemical reactions by extracting heat from the surrounding or liberating heat to the surrounding while undergoing an endothermic or exothermic reaction respectively. The Thermally Activated Cooling (TAC) system developed by Thermax Ltd. is a device one of its kind. It comprises of metallic powder which undergoes endothermic and exothermic reactions at different temperature. When arranged in a proper cycle desired cooling effect can be obtained via this process, The fin tube heat exchangers comprise of metallic powder and provide a control volume for reactions and a conductive surface for heat transfer. The amount of metallic powder in the heat exchanger is proportional to its performance, which is directly proportional to the COP of refrigeration system. The agenda of this project is to enhance the material filling process which is a crucial stage and requires a lot of time.
