由于不同气候条件下存在不同要求,为了在欧洲不同地方建立统一的规范,或在单独的应用场合指定其特性,大多数要求是通过分类给出。
某些要求可能仅用于某些特定的场合下,或者是单一场合。
1 范围本标准给出了部分或整个建筑通风或空调系统中,通过风管送风或回风的空气处理机组的试验方法、试验要求和分类。
本标准不适用于以下机组:a)建筑内用于有限面积的空调机组,如风机盘管机组b)用于住宅建筑的机组c)主要用于制造过程中通风机组除了箱体的热性能和声学性能,试验方法和要求对整机和任何单独功能段都适用。
过滤器旁通测试不适用于测试高效率的粒子空气过滤器(HEPA)。
注:HEPA过滤器推荐安装在空气处理机组的下游,这种安装应该依据合适的过滤器标准进行泄漏测试。
箱体热性能的试验方法适用于不同结构的对比,但是不适用于计算通过箱体的热损失或者是否存在冷凝的风险。
同样的,箱体声学性能的试验方法适用于不同结构的对比,但是不适用于对特定的机组给出准确的声学数据。

另外,机组可以包含一个带有一个或多个百叶窗和风阀的进风段,一个混合段,热回收段,一个或多个热和冷的盘管,加湿器,消声器和附加装置,如控制段、测试段等。
3.2 空气处理机组(模拟箱体)一种特殊的试验机组(如8.3.2定义),可用来对一系列或单个箱体的典型分级、对比或归类进行测试。
4 用真实机组和/或模拟箱体确定机械性能为了明确的区分,在本文中对模拟箱体采用字母M标示,对真实机组采用R标示。
模拟箱体和真实机组的测试标准详见表1。
表1 模拟箱体和真实机组的测试标准5 箱体的机械强度5.1 要求和分类空气处理机组的箱体可按照表2的等级进行分类。
表2 空气处理机组箱体强度分类为了明确的区分,测试中经常需要对模拟箱体或真实机组进行标示,模拟箱体采用字母M标示,真实机组采用R标示。
举例:D3(M)D1和D2等级的箱体设计和选择时应该保证面板和框架方向上任一间距的最大变形不超过表2规定的限度值。
(见图2)在选择的设计风机转速下,D1、D2、D3等级的箱体应该能够承受最大的风机压力(不是冲击压力)。
不会发生永久的箱体变形(框架/面板每米间距最大滞后±2.0mm)或损坏。
表3 测试压力真实机组的某部分如果工作在正压下,则应该在正压下进行测试,真实机组的某部分,如果工作在负压下,应该在负压下进行测试。
在生产厂家和购买者之间应该注明测试压力的偏离值。
A 面板变形B 框架变形图2 空气处理机组面板和框架间距的说明真实机组承受最大设计风机压力的能力可以通过以下方式演示。
在得到制造商和购买者预先同意的情况下,通过将机组进口堵死,运行风机直至它的最大设计运行速度。
直吹机组下游段可以通过将空气处理机组出口完全堵死来证实。
应该标明任何特殊的要求,例如机组要求具有承受防火阀的突然关闭导致的突加荷载的能力。
5.2 测试当空气处理机组在测试工况下运行时,变形测量的准确度应该在±0.5mm以内。
例如,参照图3,在R’S’间距上测得的变形X’X”,在PQ间距上测得变形为XX”。
变形X’X”是面板硬度的函数。
变形XX”是面板和框架硬度的函数。
框架变形是RR’和SS’。
例子PQ=2mR’S’=RS=1m测量变形XX”=8mm测量变形X’X”=5mm因此,间距R’S’的变形是5mm×m-1,间距PQ的变形为4mm×m-1。
测量相对变形的最高值来决定其等级。
在这个例子中,R’S’(最短的间距)的变形决定了满足等级D2。
图3 空气处理机组面板和框架的变形6 箱体空气泄漏6.1 要求和分类6.1.1 仅在负压下工作的机组组合空气处理机组的空气泄漏应该在-400Pa的压力下测试,其结果不应超过表4给出的可适用的泄漏率。
表4 空气处理机组箱体空气泄漏等级(-400Pa测试压力)注1:表4给出的最大空气泄漏等级依据prEN1507和prEN12237(例如L2=B)定义的风管泄漏等级,但是测试压力不同。
注2:等级L1的机组适用于特殊的场合,如洁净房间。
如果机组箱体的测试压力偏离400Pa,测试的泄漏率可以采用下面的公式转化到参考压力下:65.0m 400400f f ⎪⎭⎫ ⎝⎛=测试压力 (1)式中:f m 实际测试压力下的泄漏率 (l×s -1×m -2) f 400 -400Pa 下的泄漏率 (l×s -1×m -2),见表4。
除非另有说明,应用的泄漏率是空气处理机组过滤器效率的函数。
如果机组内不止一个空气过滤等级,则分类应该基于最高级别的过滤器效率。
注:对于一些特殊应用场合,在取得一致的情况下,泄漏等级可以不依赖于过滤器等级。
即使箱体没有安装过滤器,等级L3仍推荐采用。
6.1.2 同时在正压和负压下工作的机组空气处理机组如风机下游压力超过250Pa 时,应该和机组其他部分分开,进行正压段的空气泄漏测试,如果正压不超过250Pa ,进行负压测试已经足够。
适用于正压段的测试压力应该是700Pa ,或者是空气处理机组最大正的工作压力,两者取值大者。
机组其它部分的测试参照6.1.1。
应用的空气泄漏等级依据紧临风机上游的过滤器效率。
也允许对整个机组在正压或负压下进行测试。
功能段在700Pa 正压下的空气泄漏等级如表5所示。
表5 空气处理机组箱体空气泄漏等级,+700Pa 测试压力下注:等级L1的机组适用于特殊的场合,如洁净房间。
如果机组的测试压力偏离700Pa ,测试的泄漏率可以采用下面的公式转化到参考压力下:65.0m 700700f f ⎪⎭⎫ ⎝⎛=测试压力 (2)式中:f m 实际测试压力下的泄漏率 (l×s -1×m -2) f 700 700Pa 下的泄漏率 (l×s -1×m -2),见表5。
6.2 试验6.2.1 试验装置试验装置如图4所示,采用一个带有风管的风机,至少能够满足在给定的测试压力下的预测泄漏率。
图4 测试箱体泄漏的装置(负压测试). 典型例子如果相对于泄漏测试装置而言,空气处理机组太大时,或者运输时由于通道的限制要求机组以功能段或部分组合段来测试,在测试开始前分段要事先取得制造商和购买者的同意。
当有热回收装置安装时,送风和排风段应该按照单独的装置分别测试。
6.2.2 试验准备测试机组应该按照使用要求安装在某一平面上,并且按照安装说明书给出的方法连接机组。
如果需要可以安装堵板,堵板的安装采用和组装连接相似的方法。
测试前,用于电、空气或水的开口应完全密封。
如果风阀在里面,则测试前风阀应该拆除或采用堵板封死。
空气处理机组不应该对标准产品进行额外的密封。
如果已经征得同意,则可以进行。
6.3 试验流程开启测试风机,调整被测试机组内部的试验静压,使其达到规定值的5%以内。
维持静压恒定5min,直到压力稳定才开始记录数据。
记录泄漏量和测试压力。
6.4 确定允许的泄漏率从名义外部尺寸计算箱体表面积,包括被堵的空气进口和出口面积。
不构成箱体气密性的部分组件面积应被排除掉。
当测试压力偏离指定的标准测试压力值时(最大偏差为±5%),泄漏结果应该转化到表4和/或表5中用于对泄漏等级分类的测试压力下。
从表4和表5确定最大的允许泄漏,如果合适的话,与被测试机组在试验下的箱体面积联系起来。
如果测试的泄漏率不高于允许的泄漏率,则机组达标。
如果机组不得不以功能段的形式进行测试,那么各段的泄漏率之和应该作为达不达标的判断依据。
7 过滤器旁通泄漏7.1 要求7.1.1 说明过滤器单元的空气旁通会降低过滤器的有效效率,特别是高效过滤器,因为旁通空气没有经过过滤。
