The Fleet Test and Evaluation team partnered with Schneider National, Volvo, and International Truck and Engine to quantify thermal loads in trucks, identify areas for improved thermal management, and evaluate thermal management technologies.
NREL quantified the heat transfer characteristics of a Volvo truck (middle). The infrared images show higher heat transfer from the truck with uninsulated windows (left) versus the truck with insulated windows (right).
The studies are part of the CoolCab project, a government-industry collaboration that focuses on the design and integration of advanced thermal management technologies in long-haul trucks. Work on the CoolCab project, which includes developing computer models of truck cab heat transfer and climate control and working with truck and idle reduction technology manufacturers to define idle reduction system requirements, is ongoing.
The results of the first study completed under the CoolCab project are featured in Thermal Load Reduction of Truck Tractor Sleeper Cabins (PDF 863 KB). Download Adobe Reader.
