Résumé

This paper provides the main results of research and development (R&D) carried out at the Odessa State Academy of Refrigeration, Ukraine, in cooperation with National Taiwan University, Taiwan, in the area of solar and waste heat-driven ejector refrigerating machines (ERMs) that operate with low-boiling working fluids. The guidelines of our R&D activity in the area of ejector refrigeration technologies include the following main methods of ERM improvement: a) appropriate selection of environmentally friendly, and preferably natural, working fluids; b) optimum design of supersonic ejector flow profiles and ejector constructions; c) optimization of ejector refrigeration cycles and operating conditions; d) development of autonomous ERMs using non-conventional and thermally driven feed pumps; and e) development of combined, hybrid, and multipurpose systems with application of various ERMs. Based on the obtained results, advanced high-efficiency solar and waste heat-driven ERMs are developed and suggested for application in different areas.
