10. DESIGN & DEVELOPMENT OF COOLING SYSTEM BY USING LPG

Refrigeration has made the milestone in human life. Since from very long time the human being has developed so many ways of refrigeration for preserving food, cooling water, etc. but yet the techniques are developing. The science of refrigeration has developed so many ways to i mprove our lifestyle.Our paper considers law of conservation of energy maximum utilization of the fossil fuel and saving energy. This project has done LPG as refrigerant, instead of using closed cycle as it is used in normal practice (VCR); the open cycle has been used. Before burning the LPG in burner, it is passed through the expansion device and evaporator and produces the refrigeration effect without using electric energy.LPG is cheap and posses environmental friendly nature with no ozone depletion potential.
