Abstract
The invention is related to a method and an apparatus for controlling a ventilating system or an air conditioning system of buildings. This controlling is used predominantly in industrial real estates and serves for the establishment and maintenance of the desired room conditions. The method for controlling a ventilating system or an air conditioning system according to the invention uses the air density as the essential parameter for the controlling. The air density depends on the temperature, the air humidity and the air pressure. The air density difference between the introduced air and the room air is kept small.

1-16. (canceled)
A method for controlling a ventilating system, comprising:
- detecting an air density in an inlet air area and an air density in a room to be ventilated;
- determining an air density difference between the room to be ventilated and the inlet air area;
- and
- based on the air density difference, controlling the ventilation system so that the air density difference does not exceed a predetermined amount.
An apparatus for controlling a ventilating system, comprising:
- at least one temperature sensor, air humidity sensor, and air pressure sensor for detecting an air density;
- and
- a controller configured to adjust the air density based on the detected air density.
