Fabrication of Low Cost Refrigeration System Using LPG.

Abstract

Refrigeration is the science of maintaining the temperature of a substance below the atmospheric temperature That is done by removing the heat from the substance that needs to be cooled. A general refrigeration system uses electricity and Chlorofluorocarbon to accomplish the task. Chlorofluorocarbon (CFC) is also contributed to the ozone depletion. As electricity is not abundant in our country, the need of an alternate to the existing system has arisen. In such case, LPG refrigeration system has proven to be an effective for remote areas such as research sites, mines, & deserts and also free of pollution. Many engineering analysis has been done in the recent years in LPG refrigeration system, but practical implication of such analysis is yet to be reported. We will investigate the performance parameters is the refrigeration effect in certain time. A LPG powered refrigeration system has been fabricated by using different components and measuring instruments. High pressure gas from LPG was regulated to low pressure and it is directly fed to the throttle valve where further drop of pressure and temperature occurs. This low temperature gas passes through the copper tube in the refrigerating chamber absorbs heat from the chamber and thus produce refrigerating effect.
