Ejector Refrigeration Technologies: an Overview

Devendra Kumar. Joshi


The objective of this paper is to provide an overview on ejector refrigeration systems and to provide useful guidelines regarding background and operating principles of ejector. The development history and recent progress in ejector refrigeration systems discussed. For these reasons, the research activities in this sector are still getting higher and higher to solve the essential points that make these systems which are not yet reached to compete with the conventional vapour compression system. However, a lot of research work still needs to be done for the replacement of conventional refrigeration systems.
