Waste Heat Driven Hybrid Refrigeration System: A Review

D. K. Joshi


The objective of this paper is to describe a newly-developed hybrid refrigeration system .This hybrid refrigeration system , combination of a vapor compression refrigeration system driven by the high grade electrical energy and heat driven an absorption refrigeration system .Absorption system activated by waste heat available from the condenser of vapour compression system to produce the required necessary temperature in generator to vaporize refrigerant. However an electrical heater in the generator is provided to give additional heat, to increases the temperature and pressure of refrigerant vapours. An absorption-compression hybrid refrigeration system is studied, and it can recover maximum condensation heat for the generation of refrigerant vapours.
