The behaviour of a hybrid compressor and ejector refrigeration system with refrigerants 134a and 142b

Performance of ejector cooling system with thermal pumping effect using R141b and R365mfc

“…We have shown experimentally that R365mfc can replace R141b at no payoff of system performance as long as the ejector design is optimized. (4) In the solar-powered ejector air conditioner [21][22][23][24][25][26], the ejector cooling cycle and vapor compression cycle would be combined together as shown in Fig. 13.…”

A theoretical study of a novel regenerative ejector refrigeration cycle

“…The booster assisted ejector cycle was proposed and studied, which provides an increase of its performance by using compression enhanced ejector [7,8]. Arbel and Sokolov [9] and Hernandez et al [10] also proposed a hybrid compressor and ejector refrigeration system, which using a mechanical compression subsystem to increase the COP of ejector refrigeration system. In addition, Yu et al [11] and Shen et al [12], respectively, presented a new configuration of a bi-ejector refrigeration system, using a jet pump to improve the performance of ejector refrigeration systems.…”

Ejector refrigeration: A comprehensive review

“…According to the authors, a combined CERS with moderate condensing temperatures producing air-conditioning, hot water, and solar space-heating could be a very feasible and economical system. Hernandez et al [174] tested R142b and R134a on the same systems, driven by solar energy and considering the ice production application: the system using R134a at a moderate T c (approx. 30°C) exhibited the best performance, while the use of a higher T c with R142b provided better performance.…”
