Errors Resulting from the Use of Single-Zone Ventilation Models on Multizone Buildings: Implications for Energy Conservation and Indoor Air Quality Studies
多区域建筑使用单区域通风模型产生的误差:对节能和室内空气质量研究的影响
Errors resulting from treating a house as an enclosure surrounding a single, well-mixed volume of air are explored in detail for a ranch house with a basement. A fairly typical ventilation pattern is assumed, and three quantities — the air exchange rate, the indoor pollutant concentration from a given emission, and the energy required to heat infiltrating air — are calculated and compared using both the one- and two-zone models for this house. In general, the errors were around 10% to 20% if the basement was included in the one-zone models and 30% to 40% if the basement was neglected. Other factors that affect the magnitude of these errors include the length of a pollutant release, the outdoor temperature, and the air exchange rate measurement protocol, as well as the particular ventilation characteristics of the house.Units: Dual
