Petroleum gas is stored in a liquefied state before its utilization as fuel. The energy spent for pressurizing and liquefying isn’t recovered later. If it’s swollen in associate degree evaporator, it will get vaporized and absorb heat to produce cooling. This property has been used for refrigeration and air conditioning. So that the liquefied form of LPG can be used for cooling and the expanded LPG gas can be further used for combustion as a fuel. In this refrigeration system, the copper coil is kept inside the refrigerator and the LPG gas is passed through this coil as the temperature of the gas is low it starts making the refrigerator temperature decrease gradually and at the same time, other side cooking can be done. It consists of a metal frame, copper pipe, refrigerator body, pressure gauge, pipe, regulator, pressure sensor and temperature indicator. It can play an important role in restaurants where continuously cooling and heating is required also in chemical industries for refrigeration purpose. In remote areas where electricity is not available this refrigeration system using LPG system will come into use for cooling purpose.
