LPG Refrigeration and Burner System with Low Operating Cost

Abstract

In current situation supply of continuous electricity is a major problem in several areas as well as city also. At such places, this project will be very helpful for refrigeration various item like food, medicine, etc. Refrigerator became the daily part of our life. Its usage is increasing day by day. On the other side, its harmful effect to environment also increasing. We need to reduce this harmful effect, but we can’t avoid using refrigerator. Rather than we can use some other techniques to produce refrigeration effect and also reduce usage of electricity. The Objectives of this project “LPG Refrigeration and Burner System with Low Operating Cost” are: Compare the important characteristics between LPG refrigeration system and traditional refrigeration system, to obtain the characteristic benefits of LPG refrigerant, to determine the COP of refrigerator using LPG as refrigerant, to benefit the Cooling effect at free of cost by eliminating the compressor. Our proposed is very simple type of refrigeration system, the high-pressure LPG is passing through a capillary tube and expands. After expansion the phase of LPG is changed and converted from liquid to gas and then it passes through the evaporator where it absorbs the heat and produces the refrigerating effect. After evaporator it passes through the gas burner where it burns. We were able to do a successful trial and got some positive output from the setup. We also try to run gas cylinder at lean position and got some amazing result but there are some limitations at this time.
