Performance Analysis of Heat Operated Ejector Refrigeration System with Natural Refrigerants R-717 and Propane

Jitender Kumar, Nitin Jain

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. For validation of the mathematical / theoretical model, the performance for R11 was simulated on the computer program by varying the evaporator temperature from 277 to 289K, the boiler temperature from 336K to 358K, the condensing temperature from 298 to 303K and by choosing the area ratios (Ar) 4.0, 5.76 and 7.84. The theoretical performance computed using the model is compared with that of experimental data available in the literature. The calculations of the performance of R717 and Propane have been made taking the following operating temperatures.
