IO-Scan

Development of a photometric measurement method for determining the air exchange rate in indoor areas

Motivation

  • Cost-effective, real-time assessment of indoor air quality in the form of air exchange rates
  • Verify and optimise the effectiveness of ventilation systems in occupied areas
  • Ability to evaluate aerosol reduction through the interaction of window ventilation, building ventilation system and mobile room air cleaners

Project Objective

  • Self-calibrating measuring system
  • Deviation from previous trace gas measurements should be within 10%.
  • Real-time results can detect and evaluate the influence of changes in the ventilation system during the measurement process
  • Intended measurement depth in the room: 1 m to 50 m

Solution Approach

  • The introduction of mist aerosols into the room air influences the light transmittance to be measured.
  • Transmittance of an air-aerosol mixture and use of measured transmittance to determine air exchange rate
  • Integral real-time optical measurement over individual indoor distances
