ASSEMBLY HAVING A NUMBER OF HEAT EXCHANGERS, AND METHOD FOR EVAPORATING A WORKING MEDIUM

The invention relates to an arrangement having multiple heat exchangers and a method for evaporating a working fluid by transferring heat from a heat source medium, which can be used in a particularly advantageous manner in connection with a system and a method for recovering energy from waste heat in a thermodynamic cycle, in which the waste heat is used as the heat source medium. In the arrangement with multiple heat exchangers, each heat exchangers has a heat source medium through passage and a working fluid chamber separated from that, and the heat source medium through-passages of the heat exchangers are or can be serially interconnected in a ring arrangement, wherein between the heat source medium through-passages of any two serially consecutive heat exchangers in the ring arrangement, one valve means is provided in each case, wherein a supply line for the heat source medium is provided, which can be connected selectively to the inlet of the heat source medium through-passage of each heat exchanger, and wherein a discharge line for the heat source medium is provided, which can be connected selectively to the outlet of the heat source medium through-passage of each heat exchanger.
