Performance analysis of the different Organic Rankine Cycles (ORCs) using dry fluids
This paper presents the first and second laws of thermodynamics analysis for organic Rankine cycles (ORCs), using dry organic fluids as the working fluids. The dry organic fluids for this study were R227ea, RC318, R236fa, Isobutane, R600a, R245fa, HFE7000, R123 and R113. Effects of the operating parameters such as turbine inlet temperature and pressure on the thermal efficiency, exergy ...

Energy and exergy analysis of a novel multigeneration system producing cooling, heating, power and pure water
A novel multi–generation system producing power, pure water, cooling and heating is proposed and analysed in detail. The system comprises a hybrid generator-absorber heat exchanger (GAX), the Organic Rankine Cycle (ORC), the absorption heat transformer (AHT) and a desalination system. For comparison purposes, three working fluids, including R123, Isopentane and n–butane are considered in the ORC. ...

Renewable resource Trechwitz ORC - Case Study
This plant has an electrical output of 800 kW and a thermal power of 760 KW. At the biogas plant in Trechwitz, an unconventional heat utilisation model was installed. The waste heat from the CHP unit is used to generate power in an ORC unit (Organic Rankine Cycle). The heat goes into an evaporator, and the operating liquid is converted into pressurised steam. The steam is depressurised by a ...

Utilisation of deep geothermal energy for heating purposes
The Hot-Dry-Rock-(HDR) technology allows a location-independent utilisation of geothermal heat, because aquifers in deep formations, i.e. layers filled with water, are not necessary. The flow paths for the circulating water in a depth of 4 km are created by hydraulic fracturing of existing gaps. Due to the fact that this new technology is quite cost-intensive, high annual load duration of the ...
