一种用于确定建筑物气密性的低压“准稳定”脉冲技术已经被开发出来,并与标准的风门技术进行了比较,用于现场测试一系列英国家庭。已报道的用于确定建筑物气密性的低压空气脉冲装置(APU),经过与优化算法、压力参考和系统构建相关的几个开发阶段,已在各种测试和环境条件下进行试验,以评估其重复性和准确性。作为英国住宅的代表,这些房屋的漏风程度大多很高,导致能源性能差,室内环境不平衡。脉冲技术的结果也与标准的风门技术进行了比较。对两种方法的结果进行了比较,表明脉冲法是一种可靠的低压建筑物渗漏检测方法。在相同条件下连续试验的重复性在平均值的±5%以内,在不同环境条件下试验的重复性在±8%以内。研究还表明,要实现所需的准稳定流动,必须选择正确的储罐/阀门组合。已经进行了添加已知开口的准确性测试,并表明当测试条件不受控制时,很难消除不确定因素,以便进行干净的比较。
A low pressure ‘quasi-steady’ pulse technique for determining the airtightness of buildings has been developed and compared with the standard blower-door technique for field-testing a range of UK homes. The reported low pressure air pulse unit (APU) for determining the airtightness of buildings, through several development stages related to optimizing the algorithm, pressure reference and system construction, has been trialled under various testing and environmental conditions to assess its repeatability and accuracy. The houses, representative of the UK housing stock, mostly have high levels of air leakage; resulting in poor energy performance and imbalanced indoor environments. The results of the pulse techniques are also compared with the standard blower door technique. A comparison between the results obtained using the two techniques is presented, which indicates that the pulse technique is reliable for determining building leakage at low pressure. Repeatability of consecutive tests in identical conditions is found to be within ± 5% of the mean, and within ± 8% when tested under different environment conditions. It has also been shown that the correct tank/valve combination is necessary to achieve the required quasi-steady flow. Tests for accuracy using the addition of known openings have been conducted and shown that uncertainties are hard to eliminate for a clean comparison when testing conditions are not controlled.
