Noise from ERV in Closet
John Warstler|Posted in一般的问题on
我目前在做一个自我构建高绩效house 23′ x 35′ interior in climate zone 6. It is essentially a modern raised ranch as the lower level is only 3′ below grade due to a high water table. The upper level has an open concept with 6/12 vaulted ceiling. The only enclosed area is a half bath and walk in closet/pantry area.
我的较低级别的墙壁是ICF，所以通过这些墙壁排气和进气并不实用。没有条件的阁楼空间或相当大的机械室，我的选择有限。
房子的北端，基本上是占地面积的1/3或12'x 23'，所有房间都需要陈旧的空气;厨房，半浴室楼上，主浴室在下面。下面的主要卧室需要新鲜空气。7'x 4'走在壁橱里，但到了主浴室。因此，理想情况下，在壁橱中安装ERV会最大限度地减少管道工作。向上层提供新鲜空气不应该是一个问题。然而，壁橱中的噪声系数绝对可以是一个因素，并使其成为一个不期望的安装位置。
对于ERV的噪音产生的任何第一手经验都将受到极大的赞赏。谢谢

I built a house with similar dimensions and layout in 2001 and installed a Renewaire ~155cfm HRV. The mech closet was 5 feet from the primary bedroom, separated by a half bath. No issues with noise. I've also installed several smaller Broan and Panasonic HRV/ERVs in small houses without noise complaints. I would recommend the following:
1. Suspend the unit from straps or chains to minimize transmission of low-frequency vibration through framing.
2.仔细的Ashrae 62.2相应地计算和尺寸，不大于通用通气所需的大小。如果您需要更多的浴室或烹饪器排气，我建议为那些目的推荐专用的粉丝。
3. Select/size the unit for constant operation. I've found that for the low-level mechanical "white" noise, mostly what bothers me is starts and stops. If you can find a unit that can be adjusted so that it can run constantly and provide the recommended cfm, you can pretty much eliminate the start/stop issue.
4.使用推荐的管道尺寸，不小，以保持速度低。
5.使用少量的适当安装的柔性管，与本机相邻，以提供额外的声音消声。
Great info, thanks for sharing. I’m looking at either Renewaire EVS or the Panasonic Intelli-balance 100. Both units offer variable speed settings which sounds, based on your suggestions, desirable. I’m an owner DIY builder, not by profession. I’m learning as I go and am suffering a bit because these items weren’t planned well in the initial stages. Thanks again.
我们建造了多房屋，楼层和无线上线。Lunos单位的好地方！
I considered the Lunos initially, but did not plan well. Two pairs would be needed and I did not consider the large penetrations in the ICF prior to the pour. They would have been perfect for the upper level. Thanks
Renewaire EV Premiums有EC粉丝可以拨入您需要的CFM。我会认为他们更安静。大似乎是矫枉过正，但可以拨到40 CFM，并具有巨大的核心，使其具有很高的核心。
在低流量时，它不会是一个问题。问题是在提升时，你会听到它。这不是一个响亮的升压是响亮的，它比低流量更响亮，这是你会听到的。例如，我的ERV是在厨房里的橱柜里。除了在提升时运行时，我从不注意到它是开启的。
我所做的就是用一个门/门户面板勾勒出衣柜背面的迷你咕咕声。在那里安装装置并将墙壁朝向卧室。这将为您提供更好的声音分离加，它将更轻松地使过滤器更换。乔恩有一些优秀的分，如果你希望它保持安静，请务必遵循＃1，＃4和＃5。
避免任何PSC鼓风机，这些倾向于有一个60 Hz HUM，很容易通过大多数轻质的木结构来传播。仅使用ECM鼓风机选择单位。
如果您希望将墙壁保持在最低限度，请查看双通风盖。Panasonic一个人对50cfm的唯一效果很好，来自Lifebreath的一个比100cfm更好，更好。
有专门从事混凝土的公司;它们可以通过ICF轻松钻四个洞;可能值得。
