An indirect estimation of automotive demister performance

Motor vehicle users expect greater comfort and refinement in vehicle performance. Demisting systems are often considered to produce uncomfortable air flows and noisy operation. To prevent the user simply switching off the system and compromising occupant safety, manufacturers are investing more in demisting and climate control to improve detailed performance, whilst maintaining comfort and refinement. An indirect performance estimation would be extremely desirable, using less climatic test facility time and allowing prediction of end performance for a range of conditions An experimental investigation has been carried out to reproduce glass misting in a purpose built environmental facility, at conditions representative of typical car markets.
