Air velocities inside domestic environments: An important parameter in the study of indoor air quality and climate

摘要: Very low air velocities were measured in six occupied homes and one unoccupied house particularly when forced-air air-conditioning systems (i.e., HVAC) turned off. Segregating the velocity data by monitoring site, median of 4.2, 4.3, 10.2, 12.4 cm/s found master bedroom, basement, kitchen dining/living room house, respectively. In homes, comparatively high kitchens correlated with increased occupant activities use ceiling and/or exhaust fans. HVAC systems, from 5.8 to 6.2, 3.2 5.7, 1.5 8.1, 4.4 15.5. operation three houses The lowest 1.1 was a parent's where purposely limited These raise concern that movement may sometimes be inadequate for quantitative passive pollutant vapors. Ten 50% reductions sampling rates are reported literature monitors at ranging <0.7 25 2 cm/s, addition, limit off-gassing evaporatively controlled emitters decrease thermal comfort inhabitants under warm humid conditions.
