Abstract: The present invention relates to an energy recovery system (51), which withdraws heat from a feed medium (52) containing heat energy, and—which has a heat transfer system (53) for this purpose, in order to transfer heat energy from the feed medium to a useful medium (54). According to the invention—the heat transfer system (53) has a separation system (57) which spaces apart the two media (52, 54); the heat transfer system (53) has at least one first exchanger zone (35), which allows the transfer of heat from the feed medium (52) to the useful medium (54) as long as the temperature of the feed medium is higher than that of the useful medium (54, 54?); and—the heat transfer system (53) has at least one second exchanger zone (56), which allows the transfer of heat from the feed medium (54, 54?), even when the temperature of the feed medium is lower than that of the useful medium.
