Philharmonie in Luxembourg

Philharmonie, Luxembourg

The Philharmonie, opened in 2005, has a prestigious location on a hill in the capital of the Grand Duchy of Luxembourg. The extravagant concert hall, designed by the highly regarded French architect Christian de Portzamparc, has three completely different halls on a total floor space of 20,000 square meters:

The large concert hall Salle de Concerts Grande-Duchesse Joséphine-Charlotte for an audience of up to 1,500 and 120 musicians; in the basement, the small Expace Découverte hall with 120 seats and the chamber music hall Salle de Musique de Chambre adjacent to the main building, accommodating an audience of 302. In terms of layout, the white main building is shaped like an eye; the steel and glass facade is visually dominated by 823 white columns, each 20 meters high and 30 centimeters in diameter. Condair Dual hybrid humidifiers from Walter Meier ensure great air quality and comfortable humidity.

Condair DL

The Condair DL is the next generation of the Condair Dual2—the world's most successful system for adiabatic humidification. Its hygienic credentials have proven successful in practice and were verified and certified by independent organizations with public responsibility.

Hybrid humidification relies exclusively on the advantages of atomization and evaporation. This results in the sustainable resolution of key problems which can emerge when these technologies are used in isolation. The humidification system is therefore the first choice in terms of hygiene, energy efficiency and cost-effectiveness.

Patented HygienePlus® method

Basically, air conditioners and humidification devices are not sterile areas. Even when humidifying water of drinking-water quality is used, this is never completely germ-free. Therefore, microbes can always settle and form hazardous biofilms in humidifiers and in damp areas of air conditioners. Suitable hygiene measures are therefore essential to hinder the growth and propagation of pathogens in adiabatic humidifiers. The germ diagram points out the rapid propagation of microorganisms when no appropriate steps are taken to contain them. The patented HygienePlus® method provides for healthy air and a lasting hygienic environment.

Energy-efficient low-pressure system

The low-pressure mode of operation translates to significant energy savings due to the lesser compression work. By combining the Condair DL humidifier and the reverse osmosis of the Condair AT2, even a pressure booster pump on the humidification system becomes superfluous!

Schematic layout

Low-pressure systems generally get by with a significantly shallower design depth than high-pressure humidifiers. Due to the arrangement of the evaporator ceramics so that they cover the full area, and as a result of the spray cone of the molecular diffuser nozzles, the entire overall depth of the Condair DL can be reduced to up to 600 mm. Thanks to its compact design, the humidification chamber can also be shortened, achieving a significant saving in materials.
