Note:
Thermogravimetric systems running in the low-enthalpy range have been analysed. The carrier fluid is demineralized water coupled with a perfluorocarbon PFC or a hydrofluorocarbon HFC that operates as the working fluid. Minimum cycle temperature has been fixed, equal to Tmin = 30 °C, while the maximum cycle temperature Tmax varies in range 60-90 °C. As usual, pressure drops in the upward two-phase flow column have been evaluated as the sum of three terms: gravitational, accelerative and frictional. For several operating couples water-working fluid plant height Z and plant power W as wel as the corresponding hydraulic efficiency ? hy have been quantified. Among the different solutions analysed in the present paper, the couple water-PP 50 seems to result the most significant.
