This paper provides the main results of design-theoretical study of the hybrid carbon dioxide (??2) transcritical mechanical compression-ejector cooling cycle. The hybrid refrigeration cycle is the combination of a CO2 transcritical mechanical compression refrigeration machine (MCRM), powered by electricity, and an ejector cooling machine (ECM) driven by heat rejected in the compression cycle. Refrigerants R245fa, R601b (neopentane) and R717 (ammonia) are selected as the environmentally friendly working fluids of ECM in the present study. A method for determination of the optimal design parameters and performance of the hybrid ??2 transcritical mechanical compression-ejector cooling cycle is presented. The obtained data provide necessary information to design such systems for application in domestic and industrial refrigeration and air-conditioning systems under different climatic conditions.
