Working fluid selection of low grade heat geothermal Organic Rankine Cycle (ORC) [PDF]

open access: yesInternational Journal of Thermal Technologies, 2011
The paper presents working fluid selection of the ORC unit powered by geothermal source. A validated model was used to assess 25 working fluids belonging to different chemical compositions, HFC, HCFC, HC, mixture and inorganic. The selection criteria were based on: net produced power, thermal efficiency, refrigerant pump power consumption, evaporating ...
