Summary

Energy conversion technologies, especially refrigeration technologies, driven by the low temperature heat are gathering the momentum recently. This paper presents a novel cogeneration system for electricity and refrigeration. Compared with adsorption refrigeration system, resorption refrigeration characterized as safety feature and simple structure are involved since there is no ammonia liquid in the system. The cogeneration system is mainly composed of threehigh temperature salt (HTS) unit beds;three low temperature salts (LTS)unitbeds, one expander and some valves and connection pipes. Working pair of MnCl2-CaCl2-NH3is selected for the resorption refrigeration.Experimental results show that for cogeneration system, maximum 2.98kW cooling power is able to be obtained while maximumshaft poweris about 253kW. The cogeneration system can be utilized for the heat source temperature lower than 170°C, and the total energy efficiency increases from 0.293 to 0.417 then decrease to 0.407 and exergy efficiency increases from 0.12 to 0.16.
