该项目的目标是开发一种相对简单、准确的方法，用于测试高层建筑的整体围护结构泄漏率。开发了两种风机增压试验技术，即逐层风机门法和空气处理器法，并在两栋建筑物上进行了试验。制定了进行准确测试的标准，包括对室外空气温度和风速的限制。逐层送风机门方法允许隔离和测量单个楼层的泄漏流量，但它很困难且耗时- 我想申请。空气处理器方法使用建筑空气分配风扇进行增压。它最容易按系统级别应用于系统，而不是逐层应用。考虑了包括孔板、皮托管和示踪气体稀释在内的风扇气流技术。研究发现，示踪气体法相对容易应用，且具有较高的准确度。假设分区间泄漏的不确定度为5%，在所考虑的情况下，示踪气体测量风扇气流速率的不确定度估计为5.4%至8.8%。 单位:双引文:ASHRAE交易，第105卷，第。2

The objective of this project was to develop a relatively simple, accurate method for testing the overall envelope leakage rate of tall buildings. Two fan pressurization test techniques, the floor-by-floor blower door method and the air-handler method, were developed and tested on two buildings. Criteria for conducting accurate tests were developed, includ-ing limitations on outdoor air temperature and wind speed. The floor-by-floor blower door method permits isolation and measurement of the leakage flow rate of a single floor, but it is difficult and time-consuming to apply. The air-handler method uses building air distribution fans for pressurization. It is most easily applied on a system-by-system level rather than floor-by-floor. Fan airflow techniques including orifice plate, pitot traverse, and tracer gas dilution were considered. The tracer gas method was found to be relatively easy to apply and highly accurate. Fan airflow rate measurement uncertainty by tracer gas was estimated to be 5.4% to 8.8% for the cases considered, assuming a 5% uncertainty in interzonal leakage.Units: Dual
