A significant amount of amount of heat is wasted in electricity general, manufacturing, chemical and industrial process. Phase change material are utilized in different engineering field such as thermal storage building structures, heating and cooling systems, electronics products, drying technologies, refrigeration and cold storage. Paraffin wax (Melting Point 54C) is used as storage media due to its low cost and large-scale availability in Indian Markets. The further experimental study will show the flexibility of using paraffin wax PCMs as a storage medium in heat recovery system. This is because paraffin wax maintains its properties even after thousands of charging and discharging (melting and solidification of paraffin wax) cycles. In this paper, a heat exchanger will be designed for low temperature heat transfer fluid using paraffin wax as a phase change material. Experiments will be performed for different mass flow rates and temperature of heat transfer fluids. The effect of same on the performance of system is to be studied.
