Waste Heat Recovery : An Analytical Study Of Combined Ejector And Vapour Compression Refrigeration System.

Vapour compression refrigeration system is most commonly and domestic as well as large scale method of producing refrigeration effect. Due to higher co-efficient of performance these systems capture most of the refrigeration field either domestic or industrial. As on one hand these systems provided quick refrigeration effect and heat rejection on other hand by the chemical properties of refrigerant. The quantity of rejected heat from such systems is quite high and this heat is removed in atmosphere as a waste. This paper is a hypothetical approach towards the utilization of waste heat of a vapour compression refrigeration system. The rejected heat could be used to operate any other low grade heat required refrigeration system such as simple ejector refrigeration system. On the basis of some analytical examples we propose a combined cycle in this article. It is a suitable way of utilization of such waste heat hence improve the co-efficient of performance of a vapour compression refrigeration plant.
