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
对于带有地下室的牧场房屋,详细探讨了将房屋视为围绕单一、充分混合的空气量的围护结构所产生的错误。假设一个相当典型的通风模式,并使用该房屋的一区和二区模型计算和比较三个量——空气交换率、给定排放的室内污染物浓度和加热渗透空气所需的能量。一般来说,如果在单区模型中包括基底,误差约为10%至20%,如果忽略基底,误差约为30%至40%。影响这些误差大小的其他因素包括污染物释放的长度、室外温度、空气交换率测量协议,以及房屋的特定通风特性。单位:双引文:研讨会,ASHRAE交易,1985年,第91卷,pt。你好,檀香山2B
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
