In the ETA's Infrared Thermography Laboratory (IRLab), researchers test the thermal performance of windows and other insulated systems.
Test specimens are placed between chambers that simulate different climate conditions, including household room temperature versus extreme winter cold with high exterior wind speed. Using an infrared imaging system, the IRLab produces calibrated quantitative thermal images, or surface temperature maps, of the specimens in heat transfer experiments. This high-resolution non-contact surface temperature data help researchers understand details of thermal performance and validate computer simulations of heat and fluid flow, as well as provide a powerful visualization of detailed thermal features in heat transfer.
Researchers also use the IRLab to conduct other types of research, such as non-destructive evaluation.
