Blower Door Test Procedure
鼓風(fēng)機(jī)門測(cè)試程序
Outline 概述
The following test procedures will be required to be undertaken for the new XX Office Building.
要求對(duì)XX新建辦公樓做以下測(cè)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(fēng)機(jī)門測(cè)試是為了測(cè)試整個(gè)樓體的氣密性。是為了確保組裝，連接和*終完工的質(zhì)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(cè)試結(jié)果未達(dá)標(biāo)，所有相關(guān)的費(fèi)用都將由C700 總承包商承擔(dān)。
Test Specification
測(cè)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(gè)可供使用的指數(shù)，在此我們?cè)敿?xì)說(shuō)明主要的一個(gè)叫做n50(室內(nèi)和室外空氣在50 帕壓力下每小時(shí)的變
化，室內(nèi)被減壓或在負(fù)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(dá)到我們期望的滲透控制，鼓風(fēng)機(jī)門測(cè)試結(jié)果n50 指數(shù)不能超過(guò)0.95ach。這不是想當(dāng)然的是需通過(guò)組
裝，連接和*終完工并達(dá)到一定質(zhì)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(gè)常被用到的指數(shù)是i4，向樓體內(nèi)擠低于4 帕的壓力時(shí)室內(nèi)和室外的區(qū)別。I4 指數(shù)應(yīng)與以上所述n50
指數(shù)相符，應(yīng)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(duì)應(yīng)方法，一棟類似形狀建筑的氣密性達(dá)到PassivHaus 標(biāo)準(zhǔn)，被認(rèn)為是***的，要求i4 指數(shù)
為0.23.
Air Tightness Test Failure
空氣氣密性測(cè)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.

威盧克斯可以選擇第三方作為測(cè)試公司。當(dāng)測(cè)試結(jié)果顯示樓體氣密性未達(dá)到要求，本次測(cè)試和以
后的測(cè)試以及整改工作等相關(guān)費(fèi)用都將由C700 總承包商承擔(dān)。
