IO-Scan - Integral measuring optical scanning method
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
