Blower Door Test Procedure

鼓風機門測試程序 Outline 概述 

The following test procedures will be required to be undertaken for the new Velux Office Building. 

要求對威盧克斯新建辦公樓做以下測試程序.

A blower door test is meant to measure the air tightness of a building envelope. It to ensure proper quality of assemblies, connections and finishing. 

鼓風機門測試是為了測試整個樓體的氣密性。是為了確保組裝，連接和*終完工的質量。 

If the test results are not achieved, then any and all costs associated with engaging another contractor will be at the cost of the C700 General Works Contractor. 

如果測試結果未達標，所有相關的費用都將由C700 總承包商承擔。 

Test Specification 測試詳述 There are several indexes that can be used and we will specify the main one, which is called n50 (the air changes per hour at 50Pa pressure difference between indoor and outdoor, 

building indoor being depressurized or under negative pressure). 有幾個可供使用的指數(shù)，

在此我們詳細說明主要的一個叫做n50(室內(nèi)和室外空氣在50 帕壓力下每小時的變 化，室內(nèi)被減壓或在負壓以下) 

In order to reach the type of infiltration control we want, the n50 index should not exceed 0.95ach as a result of the blower door test. This is not to be taken for granted and can be achieved with only a proper quality of assemblies, connections and finishing. 

為了達到我們期望的滲透控制，鼓風機門測試結果n50 指數(shù)不能超過0.95ach。

這不是想當然的是需通過組 裝，連接和*終完工并達到一定質量而獲得的。 

Another index usually used is i4, expressed in m3/h/m2 of envelope under 4Pa pressure difference between indoor and outdoor. The i4 value that would correspond to the n50 specified above is 0.37m3/h/m2. 

另一個常被用到的指數(shù)是i4，向樓體內(nèi)擠低于4 帕的壓力時室內(nèi)和室外的區(qū)別。I4 指數(shù)應與以上所述n50 指數(shù)相符，

應為0.37m3/h/m2 As a way to do the correspondence, a similarly shaped building aiming at a PassivHaus standard for air tightness, recognized as the most stringent, would require a i4 of 0.23. 作為一種對應方法，

一棟類似形狀建筑的氣密性達到PassivHaus 標準，被認為是***的，要求i4 指數(shù) 為0.23. Air Tightness Test Failure

空氣氣密性測試失敗 Velux may elect to engage a third party testing company. 

In the event the test results indicate that the building has not achieved the required air tightness, 

not only will the cost of this and any future tests, all costs of the rectification works shall be borne solely by the C700 General Works Contractor. A-011-Blower Door Test Procedure-20110902A 

威盧克斯可以選擇第三方作為測試公司。當測試結果顯示樓體氣密性未達到要求，

本次測試和以 后的測試以及整改工作等相關費用都將由C700 總承包商承擔。
