Development of New drying system using salt solution

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.
