  • the heat coupling device 31, 32 furthermore has an exhaust gas inlet 32 for feeding the exhaust gas to an exhaust gas heat exchanger 35 of the ORC device 20. Heat is transferred from the exhaust gas to the working medium and used to preheat the working medium (upstream of the evaporator).
  • the ORC container 10 also includes an exhaust gas outlet 33 on the top of the ISO container 11.
  • the heat can be transferred directly to the working medium, i.e. direct evaporation or preheating via a heat exchanger or via an intermediate circuit with another heat transfer medium.

  • a connection can be made using standardized connecting elements, e.g. corner castings.
  • cooler 53 associated with the internal combustion engine generates heated air and often has an upwardly directed exhaust air duct which must not be covered.
  • connection position for motors varies and a diversion is necessary if the connections from / into the container are not directly above one another. This would then have to be implemented within the ORC container which in turn reduces the area within the container available for the ORC system and thus reduces flexibility. A reduction in the available container space also results in a reduction in the size of the cooler surface and / or the exhaust gas heat exchanger surface. If these are each below the specific design point, this has performance-reducing effects and thus damages the profitability of the system.
  • the ISO container with additional feet is a standard product with no changes in design or manufacture. Only minor adjustments are necessary during installation (connecting the ORC container to the aggregate container). In addition, there is flexibility in installation and pipe routing instead of being determined in advance by a specific combination.
  • the ORC container can already contain external installation components in the available volume - no further logistics are necessary. A maximized installation space can be used in the ORC container. An exhaust air duct is possible on a side facing away from the coolers of the ORC container.
