About profi-air PLAN
With the profi-air PLAN software, FRÄNKISCHE offers a free planning tool for creating ventilation concepts. profi-air PLAN supports you as a planner, architect, installer or energy consultant in designing our profi-air ventilation systems according to the new DIN 1946-6 standard (12/2019 issue) in just a few minutes.
After entering the building data, the software determines whether ventilation measures are required or not. The software prepares the required ventilation concept according to DIN 1946-6 immediately from the data already provided and automatically suggests suitable ventilation units and the necessary accessories from FRÄNKISCHE's profi-air range. This way, you can put together the right system quickly and easily.
In the end, profi-air PLAN shows you the complete product solution. To finish the planning process, you have the option of creating a report that not only presents a breakdown of all the important data but also optionally contains a bill of quantities and a wiring diagram. (The data can also be selected in pdf, xlsx or GAEB file formats).
About DIN 1946-6 (12/2019)
The DIN 1946-6 standard shows possible solutions for achieving sufficient air exchange in apartments and thus creates regulations for the ventilation of residential buildings in new builds or renovations. It applies to the free and fan-assisted ventilation of living spaces and similarly used groups of rooms (utilisation units) and specifies the requirements for planning, execution and commissioning, operation and maintenance of the necessary ventilation components (source: DIN 1946-6 2019-12).
The ventilation must operate independently of the user, i.e. even when the inhabitants are absent.
The planning and design criteria are intended to ensure that a sufficiently large fresh air volume flow is supplied to living spaces. This is necessary for the inhabitants for reasons of hygiene and health with occupancy according to plan. The requirements apply both to the entire utilisation unit and to each individual room.
DIN 1946-6 demands proof of four ventilation levels for sufficient air exchange under different use conditions. These were defined on the basis of experience and examinations of buildings. The four ventilation levels are based on characteristic user behaviour. According to the standard, four ventilation levels are initially differentiated in terms of their intensity. The different ventilation levels classify the performance of a ventilation system. If the air supply via building leaks is not sufficient to ensure ventilation for moisture protection, the planner must provide ventilation measures.
