Using Tracer Gas to Analyze Ventilation Performance

Engineers and building professionals often need to balance energy efficiency with optimized air quality. Heating, ventilation, and air conditioning (HVAC) systems found in various industries such as hospitals, laboratories, and passenger cabins, often need to perform to specific standards with targeted air exchange rates. Professionals can determine the appropriate air exchange rate using tracer gas.

The above example application shows the INNOVA 1403 providing a single dose of tracer gas at the supply air inlet and collecting a sample at the return air outlet. The sample is then measured by the INNOVA 1412i, with the result evaluated by the user with the Basic Ventilation Software 7650. Since the amount of the delivered tracer gas is known, it is easy to calculate the remaining concentration to evaluate ventilation system performance.

Since the INNOVA monitors utilize Photoacoustic Gas (PAS) technology, the results are extremely accurate and repeatable. This allows professionals to decide if adjustments need to be made to the HVAC system and conduct additional tests.
