The climatic change and global warming demand accessible and affordable cooling systems in the form of refrigerators and air conditioners. The energy crisis persists all across the globe. We think of recovering the energy which is already spent but not being utilized further, to overcome this crisis with no huge investment. To address this problem we designed and analyzed a refrigerator which uses the energy spent in pressurizing and liquefying the LPG. LPG is extracted at high pressure in the liquefied state from the storage device. Its pressure and the flow rate is controlled by a valve connects it to the evaporator at the requisite pressure in requisite quantity. An evaporator is housed through which LPG flows. It gets converted from liquefied state to gaseous state and expands. So it absorbs heat in the form of latent heat. Due to this process, heat from surrounding is absorbed so cooling effect is produced. This effect is magnified by an evaporator. A network of pipes containing gas is covered by thin and closely spaced fins which help in effective and fast cooling. The insulating material helps in storing the cooling effect for a longer period of time. The LPG leaves the evaporator in gaseous form; it is then directed towards the burner where it is to be used. Thus, no LPG is consumed for cooling purpose.
