The effect of recirculation on air-change effectiveness calculations.

Author(s) : FEDERSPIEL C. C.

Summary

Demonstrates that conventional methods of evaluating air change effectiveness from age-of-air calculations are affected by recirculation. Defines ventilation performance measure called the relative air change effectiveness. Shows that the relative air change effectiveness is independent of the recirculation fraction and that it may be determined solely from air-to-air calculations. Re-evaluates the data from a previously published experiment on a mechanically ventilated building using the relative air change effectiveness.
