This means that the same building height can accommodate more floors. To provide the possibly cheapest office space creates conflicts with the demand for comfort. Therefore, to reduce the room temperatures, in some cases component cooling systems are used for the ground load cooling. According to the thermal isolation regulations, an air-conditioning installation is demanded for dense facades, to prevent building...

AUDIX® TECHNICAL DOCUMENTATION Processing | Models Characteristics of the individual diffusers: • AUDIX®-...-ADSA: The fixed (-D0) or adjustable (-VD) nozzles produce a stable core jet.

This ensures that fresh air is circulated through the whole room and not just near the supply air diffuser. The temperature and the velocity are broken down quickly. • AUDIX®-...-ADSC: The support profile blades produce a stable jet set to a horizontal throw, directed slightly upwards. Due to the central...
