| Abstract | In the paper presented are the results of calculation of operation effectiveness of low temperature Clausius- Rankine cycle supplied with geothermal energy with temperature ranging up to 120?C. A concise literature survey has been presented with respect to required features of the working fluid used in a clockwise cycles as well as comparisons have been made with required features of the fluid in refrigeration cycles. Presented also has been thermodynamical analysis of low temperature Clausius- Rankine (C-R) cycle. Efficiency and power have been considered as evaluation criteria. Presented have been common features as well as major differences in requirements facing fluids with favourable properties when applied in clockwise cycles as well as compared have been with positive features of working fluids used in refrigeration cycles. |
