| Summary: | Title screen The cycle arrangement of a binary-type GeoPP using a thermal energy source with a temperature of 80 ÷ 150 °C was considered; its elements and structural connections were substantiated. A method was proposed, numerical studies were carried out to find optimal working bodies for the ORC and parameters for the operation of GeoPP in nominal and variable modes. The greatest efficiency and power in the considered modes belongs to the GeoPP operating by the ORC on the R141b freon. Since this freon is prohibited for use as having an ozone-depleting chemical structure, R245fa was selected among the ozone-safe freons considered, for which the electrical power and absolute electrical efficiency of the GeoPP have the best values at a source temperature of 80 ÷ 120 °C. R245ca and R365mfc are the most effective freons for the ORC of GeoPPs at > 120 °C Текстовый файл AM_Agreement |
