Functional description

Ventilation grilles are air terminal devices for the supply air and extract air of ventilation and air conditioning systems. They direct the supply air into the room. Ventilation grilles with adjustable blades allow for adapting the discharge direction to the local conditions. The result is a mixed flow ventilation in comfort zones and industrial zones, with good overall room ventilation.

Induction slows the airflow down, i.e. the airflow velocity decreases as the distance from the grille increases. The distance at which the airflow velocity reaches a certain defined value, e.g. 0.2 m/s, is called throw distance. The supply air jet from wall grilles that are installed near the ceiling achieves a larger throw distance than a free jet (from a grille that is not installed near the ceiling). Single grilles, groups of grilles and continuous horizontal runs all achieve different throw distances.

In cooling mode it is necessary to take account of the jet deviation towards the occupied zone, which increases as the supply air to room air temperature difference increases and the discharge velocity decreases. In heating mode the supply air jet deviates towards the ceiling. This has no negative effect on the airflow velocity in the occupied zone, but it may affect the complete ventilation of the room.

Hochzillertal – Berggasthof Platzlalm

An air of luxury. There is no reason why a cosy mountain inn should not be every bit as comfortable as a 5-star hotel.

Berggasthof Platzlalm can be found right in the popular ski resort Hochfügen, Hochzillertal, near the alpine road Zillertaler Höhenstrasse. The chalet offers 30 sleeping possibilities, a great sun deck and, for ultimate relaxation: a sauna – all at an altitude of approx. 1,800 metres.

 

Its blend of traditional and modern design creates a pleasant, welcoming atmosphere. It is a place where you simply feel good.

TROX components ensure a comfortable indoor climate

 

TROX components ensure a comfortable indoor climate. Products from the air handling expert, such as swirl diffusers, grilles, disc valves, fire dampers and volume flow controllers, were installed in the mountain inn, for example, in the bar lounge and in the dining and sitting room. Naturally, the installation had to comply with technical requirements for air handling and noise,  but the visible technological elements also had to match the overall visual appearance of the rooms and lounges, characterised by beautiful old wood. The grilles from TROX were perfect for the job.

TROX products in the Hochfügen ski resort

 

Thanks to the installed components from TROX, guests will be comfortable in the inn no matter the temperature outside. Furthermore, the tried and tested fire dampers ensure a high degree of safety. TROX products create an excellent indoor climate and pleasant atmosphere – even in winter and at 1,800 metres!
