Cycle Temperature

Organic Rankine cycle (ORC) is a modified rankine cycle with working fluids, of organic material (Refrigerant). Refrigerant pentane has low boiling point, therefore ORC can be used in power plant which uses low temperature resources, such as solar thermal exhausted gases and geothermal wells. Organic Rankine Cycle (ORC) is used to convert heat energy into mechanical energy or electricity generated by a low temperature of the hot sun. The working fluid used is HCR12, HCR22, HCR134a and Pentane. Simulations performed with an organic Rankine cycle temperature and pressure with cycle tempo program. By programming the simulation cycle tempo and got the result on the maximum power a turbine to the conditions of the working fluid Pentane to the input turbine T = 700C and pressure = 2 bar can generate 2.07 kW. Turbocharger is one of the alternatives in the energy conversion of the energy of motion into electrical energy. Turbocharger rotation will be used to turn a generator and converts the energy of motion into electrical energy.

A solar thermal organic Rankine cycle (ORC) power generation system model established using R245fa as the working fluid and coupled with a solar photovoltaic generator is introduced. Thermal efficiency and exergy efficiency of the model both with and without a heat regenerator are calculated and compared. Results show the solar organic Rankine cycle system with a heat regenerator has higher thermal and exergy efficiency than the system without a heat regenerator, providing better performance in practice. This result provides a basis for further application and improvement of solar photovoltaic and the solar thermal organic Rankine cycle.
