   Heat exchangers to use waste heat in MUs  evaluated  
The waste energy produced by under-floor traction equipment in MU stock can partially be used for comfort functions by means of heat exchangers. This is already in use in modern DMU stock but not yet implemented in EMUs.
Technology field: Optimisation of comfort functions

The use of waste heat from traction equipment is a promising strategy to reduce the energy demand of comfort functions. In DMUs the measure is becoming a standard in new stock. A corresponding solution for EMUs meets more technological challenges and has not been developed yet. More R&D efforts for EMUs are justified since even for electric stock the energy efficiency potential is promising.
