The project aims at the reduction of noise produced by ventilation systems with heat exchangers, and is part of the Professional Doctorate in Engineering (PDEng) programme Energy & Process Technology. This 2-year post-MSc programme contains a design project and an educational part that will be followed at the University. The design project is carried out in close cooperation with Brink Climate Systems. The educational programme will have an in-depth and broadening character with ample attention for professional development and will be partly tailored to the design project.
