Despite this fact, such systems are not yet standard equipment in residential buildings. Comparable to the relatively small number of realised systems, there is often insufficient specialist knowledge about these systems and there are technical uncertainties in the planning and operation of the systems.
For this reason, FH Burgenland GmbH has developed a training and test stand for comfort ventilation systems that fulfils the following tasks:
- Demonstration object for explaining and analysing a ventilation system and its components
- Possibility to simulate any air conditions before entering the ventilation unit (e.g. summer / winter case)
- Familiarisation with measurement methods in ventilation technology
The training and test stand enables students as well as experienced specialists to gain initial experience with the subject of comfort ventilation and to analyse specific issues relating to a specific ventilation component.
TECHNICAL DATA:
