Optimizing waste heat recovery for long-haul trucks
- Magazine Article
A waste heat recovery (WHR) system for a long-haul truck application was examined via simulation, test bench, and public road vehicle testing as part of a joint project between
For on-road truck application, several waste heat sources were available for the ORC at different temperature levels. Based on thermodynamic calculations, production costs, and complexity, along with total cost of ownership evaluation, the decision was made to focus on the high-temperature sources from the vehicle cooling system for the ORC. This enabled a high overall ORC efficiency with a minimum number of heat exchangers.
