The new feeling of comfort in passenger cars

Bart Radema, key account manager at Airex Composite Structures, explains more about the company’s space-effi cient fl oor heating system.


Starting situation and requirements T


he railway industry is in direct competition with other passenger transportation


modes, and numerous studies have shown that reliability, cost and comfort play a decisive part in customer decisions.


Climate control is one of the determining factors for passenger comfort. The aspect of ‘increasing comfort’ faces numerous restrictions, including dimensioning criteria for the vehicles, the required cost-effectiveness, and the minimisation of installation and maintenance expense. Energy effi ciency specifi cations and the system weight are also becoming increasingly more important.


Airex Composite Structures’ innovative approach


Airex Composite Structures is taking an innovative path for heating passenger cars. The special conditions in double-decker trains were


decisive for the development of the heated fl oor panel system. The development was realised in close cooperation with the rail vehicle manufacturer Stadler Altenrhein AG.


The heated fl oor panel, with a stated service life of 30 years, consists essentially of two component parts, the sandwich panel and the heating foil, integrated into one product. This design has outstanding features. It achieves the highest class, HL3, according to EN 45545.


The standard heating power is 300W/m². The fl oor plates are equipped with temperature sensors and limiters. Since this system is based on the conventional joining technology in rail vehicle construction, it is applicable to nearly all vehicles. The weight of the heated fl oor panels is approximately 11-16kg/m² and brings a weight advantage of roughly 30%. The load per unit area for the panels is roughly 5000N/ m². The elimination of the conventional radiator elements and covers in the new system brings a substantial space advantage.

The fl oor panel is hygienically safe, since the formation of condensate water and the deposition of dirt beneath covers and channels are impossible. Together with the easy exchangeability, these properties lead to a signifi cantly lower life cycle cost.


Summary


The bottom line for the heated fl oor panels with the sandwich construction from Airex Composite Structures is that the newest comfort requirements for heating passenger cars are exceptionally well satisfi ed, and it sets new standards for climate control. The system has numerous advantages, not only in terms of cost, but also of added value, which the passenger perceives from the increased space in the sitting and standing area as well as the improved interior climate.
