Abstracts: Even with the advances in technology today, the reality is that there are still a number of places that do not have electricity more so in the developing world. However, even among the developed Western countries, there are circumstances where one will not have ready access to power; camp sites, cabins, remote cottages are a few examples of where LPG refrigerators can be used. This project is about providing refrigeration effect using LPG. LPG consists mainly of propane(R-290) and butane(R-600). The refrigerants used in conventional refrigeration cycles have a high ozone depletion and global warming effect. This project involves a small capacity refrigerator that works without electricity. The LPG is used as a refrigerant. A gas tank is used as a source of LPG. It has the advantage of using the gas as a refrigerant and then as a fuel as the cycle is kept open.
