A presentation of the design of the Organic Rankine cycle (ORC) with heat regeneration and superheating processes is a subject of this paper. The maximum temperature level in the ORC is considered to be 110°C and the maximum pressure varies up to 2.5MPa. The selection process of the appropriate working fluids, thermal design and calculation of the cycle and its components are described. With re...
To develop the organic Rankine-vapor compression ice maker driven by solar energy, a thermodynamic model was developed and the effects of generation temperature, condensation temperature, and working fluid types on the system performance were analyzed. The results show that the cooling power per square meter collector and ice production per square meter collector per day depend largely on gener...
In this study thermodynamic performance analysis of a combined organic Rankine cycle and ejector refrigeration cycle is carried out for use of low-grade heat source in the form of sensible energy. Special attention is paid to the effects of system parameters including the turbine inlet temperature and turbine inlet pressure on the characteristics of the system such as ratios of mass flow rate, ...
In this research, solar-drived integrated Hydrogen production (HP) using high-temperature steam electrolysis (HTSE) is thermodynamically evaluated. This system includes an organic Rankine cycle (ORC), Rankine cycle, Brayton cycle, solar tower, and High Temperature Steam Electrolysis (HTSE). Solar energy supplies thermal energy. This heat source is applied for generating power. This energy is us...
As a promising and advanced technology, enhanced geothermal systems (EGS) can be used to generate electricity using deep geothermal energy. In order to better utilize the EGS to produce electricity, power cycles’ selection maps are generated for people to choose the best system based on the geofluids’ temperature and dryness conditions. Optimizations on double-flash system (DF), flash-organic R...
A micro Rankine cycle system using wood and solar energies for combined production of electricity and thermal energy is studied. For low power output (< 10 kW), micro Rankine cycle design and its energy performances depend strongly on the properties of the working fluids. Organic fluids present many advantages compared to water for Rankine cycle utilizing low-grade energy as heat input, and par...
