Abstract
A method for measuring pressure differences in different premises of a building, in which the pressure difference is measured using one or more sensors (2) that measure absolute pressure. The measurement results obtained from the sensors (2) are combined with information on the efficiency of the ventilation of the building, and the pressure difference caused by ventilation is mathematically separated from the measurement result by making use of information on the ventilation efficiency at any one time.
Claims9
A method for measuring pressure differences in a building, comprising:
- establishing, in a premise of the building, at a first instant of time, a first pressure with a ventilation device of the building,
- measuring, at said first instant of time, a pressure in the premise by one sensor that measures absolute pressure,
- adjusting and changing an efficiency of the ventilation device and establishing in the premise, at a second instant of time, a second pressure,
- measuring, at said second instant of time, a pressure in the premise with said one sensor, and
- combining the pressure measured at said first instant of time and the pressure measured at said second instant of time, with information on the change of the efficiency of the ventilation device of the building at the first and second instants of time, respectively, to obtain pressure difference information as response to the change of the efficiency of the ventilation device.
