The present invention relates to a method and arrangement for recovering energy (25, 26) from any kind of heat sources (2A, 2B), during sustained environmental and economical considerations, by at least one closed circulating system comprising at least one working medium/fluid (30) into an Organic Rankine Cycle - ORC - which fluid in liquid phase is pressurized and vaporized by said heat source, after which the gaseous phase of the said fluid is expansion cooled by at least one expander turbine (21, 22) preferably comprising at least two partial stages with intermediate separation of condensate (15, 16), when the condensation cooling takes place preferably during counter current fed condensate fractions (9, 10, 11) with in stages heat transmitting, simultaneously the working fluid is preheated before the return into the vaporization stage (1), when required the condensation effect is more strengthened by some form of supplementary cooling/heat sinking stage, during production of both mechanical energy (25) as well as heat (46). Heat pump system (32) with energy well (31) or corresponding is advantageously integrated to the arrangement for production of heat (44, 44V, 46) and when required chill (44K). |
