Circulating two million cubic metres of air per hour without draughts or noise and using a minimum of energy? Yes, it can be done! The proof, courtesy of TROX can be inspected in the new exhibition hall, “Halle 11”, at Messe Frankfurt.

Although TROX had previously developed and supplied induction units of the same order of magnitude for exhibition hall 3 in Frankfurt, the ventilation technology faced a particular challenge in this project: In exhibition hall 11 with its new West entrance, a cooling effect of 27 kW per device needed to be produced.

Calculations using complex simulations established that the optimal result could be achieved using special active chilled beams, which can supply cooling air in a discharge angle varying from horizontal to vertical – depending on the current load. In total, 288 induction units with one or two-way air discharge have been installed in the two-story hall at a height of ten metres. The maximum dimensions of each device are 2.50 m x 1.80 m x 0.65 m.

The air-water systems supply the hall with 2,000 m³/h treated primary air. The Type IDH active chilled beams are designed for large halls and suitable for large thermal loads. The new exhibition hall will open for the 63rd International Motor Show, IAA Cars 2009, in September this year. The investment by Messe Frankfurt amounts to around EUR 170 million. The construction time will be 24 months in total.
