The title of this project is Development ofNew Drying System using salt solution. The topic is actually to investigate for the salt solution to be as an alternative refrigerant in the drying system. Seven types of salt involved in this project andthe properties of each salt are determine via experimental work. The process of dissolving salt has an energy change associated with it, which are endothermic and exothermic heats of solution. The main properties for the salt solution to be an alternative refrigerant in this research is the salt solution that involved in the exothermic reaction. There are three objective needs to be achieved in the project, which are to measure the heat involved of solution of salts, to relate the heat of solution involved to the two-step process of dissolving and to identify the best salt solutions for drying system. Two experimental works is done to achieve all objectives and to prove the topic given. Based on the result, three salts among seven salts experienced an exothermic reaction and the other is endothermic reaction. From the experimental results it prove that exothermic salt solution can be as alternative refrigerant, where the heat release from the reaction can be used as a drying agent. Modification to the existing refrigerator system need to be done to suited the application of salt solution as an alternative refrigerant.
