AB  - In this paper, due to the importance of energy recovery from internal combustion engines and the increasing human growing need for power and refrigeration, a two-cycle power and refrigeration system consisting of an organic Rankine cycle and an ejector refrigeration cycle is investigated analytically. The proposed system with the ability to use the ejector as an effective and economical system, can produce simultaneous power and refrigeration by drawing thermal energy from the exhaust gas and engine coolant in the form of a novel cycle. This study analyzes the proposed novel two-cycle Rankine-ejector refrigeration system (TCReRS) compared to a two-cycle Rankine-absorption refrigeration system (TCRARS). It was concluded that the TCReRS with higher output and a COP of about 69.99%, is a useful and promising system under the considered condition. The proposed system uses environmentally friendly R1233zd and R32 fluids as operating fluids in Rankine power and ejector refrigeration cycles, respectively. In addition, the effect of system performance parameters has been investigated and optimized.
