低层住宅建筑物的通风和达标的室内空气质量

Ventilation and Acceptable Indoor Air Quality in Low-Rise Residential Buildings

ANSI/ASHRAE 62.2Addendum i-2011 发布历史

The current methodology for intermittent ventilation ignored the impact of infiltration on the equivalent annual dose calculation which is the basis of this requirement. This new methodology assumes an infiltration rate of 0.02 cfm/sq. ft. of floor area and an occupancy area of 400 sq. ft./person. Higher occupancy areas and/or higher infiltration rates would result in lower equivalent annual doses than the proposed new methodology. In general, this new methodology results in lower allowable intermittent ventilation rates.
