ORC technology to use waste heat in MUs |
|
evaluated |
|
|
|
The waste energy produced by under-floor traction equipment in MU stock may be used for comfort functions. While the use of waste heat by means of heat exchangers is limited to heating, advanced technology based on the Organic Rankine Cycle (ORC) allows for the production of electric power from waste heat and thus for the use of waste energy for cooling or lighting purposes.

The use of the Organic Rankine Cycle is an interesting approach to the recovery of waste energy in MUs. In contrast to heat exchangers, ORC technology allows for a generation of power and thus for the use of waste energy for all comfort functions instead of heating only. Implementation in DMUs may become economically feasible in mid-term. In contrast, applications in EMUs are still far from being profitable. Nevertheless, given the energy efficiency potential, further progress in ORC technology should be followed closely. |
