Enhanced ejector refrigeration cycles powered by low grade heat. Part 2. Design procedures

Abstract In Part 1 of this work, the conventional and compression enhanced ejector refrigeration cycles were discussed from a thermodynamic and conceptual point of view. This paper describes the development of procedures which will enable system design, optimization and control of operation. Special attention is given to the ejector design and the recommended modification of conventional system components such as the evaporator and generator. A multi-ejector system is introduced in order to expand the range in which the system may operate efficiently.
