Embodiment Construction
[0031] Figure 1 and figure 2 It has been explained earlier. image 3 Shows the corresponding to the "Misselhorn" process of the arrangement system according to the invention with the heat transfer device according to the first embodiment figure 2 schematic diagram. The working principle of this heat transfer arrangement system is based on the series Figure 4A to Figure 4C to illustrate. Although the illustrated embodiment is based on three heat exchangers or heat exchangers operating as evaporators for the sake of illustration, the number of heat exchangers is n≧2.
[0032] When increasing the number of heat exchangers which operate as evaporators and through which the heat source medium flows sequentially, the curve shapes of the working medium and the heat source medium in the TQ diagram of the arrangement system become closer and closer. Furthermore, it can be seen that, for the sake of clarity, the working medium ducts and working medium chambers of the heat transport...

The invention relates to an assembly having a number of heat exchangers and to a method for evaporating a working medium by exchanging heat from a heat source medium, which assembly can be particularly advantageously used in combination with a system and a method for recovering energy from waste heat in a thermo-dynamic cycle process, wherein the waste heat is used as the heat source medium. In the assembly having a number of heat exchangers, each heat exchanger has a heat source medium through-passage and a working fluid chamber separated from said through-passage, and the heat source medium through-passages of the heat exchanger can be / are connected to one another in series in a ring assembly, wherein a respective valve means is provided between the heat source medium through-passages of two respective serially consecutive heat exchangers in the ring assembly, wherein a supply line for the heat source medium is provided which can be selectively connected 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 selectively connected to the outlet of the heat source medium through-passage of each heat exchanger.
Description
technical field [0001] The invention relates to an arrangement with a plurality of heat transmitters for evaporating a working medium by heat transfer from a heat source medium, and to an arrangement for evaporating a working medium by heat transfer from a heat source medium in said arrangement method of working medium. The arrangement and method can be used particularly advantageously in combination with a device and method for recovering energy from heat during a thermodynamic cycle in which waste heat is used as heat source medium. Background technique [0002] Thermodynamic cyclic processes for converting externally supplied thermal energy into mechanical work are known, for example, in the form of conventional steam engine cycles, Stirling cycle processes or organic Rankine cycle processes ("Organic-Rankine-Cycle" or ORC processes) . Different from the traditional steam engine cycle, in the ORC process, instead of water, the organic matter boiling at a lower temperatu...
