PERFORMANCE ANALYSIS OF HEAT OPERATED EJECTOR REFRIGERATION SYSTEM WITH NATURAL REFRIGERANTS; R-717 AND PROPANE

Abstract

In present study a mathematical model is developed in EES software for single phase Ejector Refrigeration System. The model is then used to determine the performance of natural refrigerants R717 and Propane. The ejector cycle of cooling is very much suitable for the applications where large amount of low-grade heat is released in the environment while refrigeration may also be required in the same application, as it is often the case in the chemical and food processing plants and automobiles. Under such circumstances, non-mechanical, thermally activated ejector machines may represent an excellent mean of heat recovery for cooling. As in coming time the refrigerants having ozone depletion potential and global warming potential will be completely phased out, then the natural refrigerants will have scope of their use in place of present refrigerants. On the basis of above, in present study the analysis of Propane and Ammonia (R717) is carried out. For validation of the mathematical / ...
