This study presents a theoretical analysis of a new combined cooling, heating, and power cycle by the novel integration of an organic Rankine cycle (ORC), an ejector refrigeration cycle (ERC), and a heat pump cycle (HPC) for producing cooling output, heating output, and power output simultaneously. Three different working fluidsnamely R113, isobutane, and R141bhave been used in power, refrigeration, and heating sub-cycles, respectively. Energetic and exergetic analyses of the proposed cycle have been conducted to demonstrate its efficiency. The thermal and exergy efficiencies are obtained as 71.08% and 38.3%, respectively. The exergy destruction rate of each component and the overall cycle have been calculated where it is shown that among all the components, the generator has a main contribution in the cycle inefficiency. Finally, the sensitivity analysis of the different key parameters on the performance of the proposed cycle has been investigated. It has been demonstrated that the proposed cycle performs well in high generator pressure and low evaporator outlet pressure, based on the first and second laws of thermodynamics.Keywords: Organic Rankine Cycle (ORC), Ejector Refrigeration Fycle (ERC), Heat Pump Cycle (HPC), Combined Cooling, Heating, Power (CCHP) Cycle, Working Fluid}
