WebJul 1, 2013 · ORCs use organic working fluids. These fluids have lower boiling points than steam/water at the same pressure, which allow them to be driven by low-grade waste heat. ORCs functioning down to have been reported [ 1 ]. By converting waste heat into mechanical power, ORCs can improve the efficiency of a wide range of thermal cycles. WebIn this paper, thermodynamic analysis of a combined ORC-VCC system powered by low-grade energy source is presented. The system is modelled in Engineering Equation Solver (EES) and its performance is assessed using two parameters: Cooling Capacity (CC) and Coefficient of Performance (COP), calculated under complete refrigeration mode, i.e., all ...
WebThe working fluid that would be suitable for the temperatures and pressures in the system was selected. The best fluid for the given conditions of superheated vapor at 120 °C and 604 kPa and a condensation temperature of 60 °C and 115 kPa was acetone. WebAug 23, 2013 · Six working fluids, including hydrochlorofluorocarbon (HCFC; e.g. R123), hydrofluorocarbons (HFCs; e.g. R134a and R245fa) and hydrocarbons (HCs; e.g. butane, isobutane and propane), are selected and evaluated to identify suitable working fluids which may yield high system efficiencies. Methods System design and working fluid selection
WebThe selection of the optimum working fluid is vital. ORC systems can produce either mechanical or electrical power from the recovered heat. One solution is to deliver the mechanical power generated by the expander of the Rankine cycle to the powertrain system of the IC engine.
