我有一个已经运作了一段时间的ERV，新鲜的空气在专门的跑步进入主起居区，但陈旧的皮卡未完成。问题是我所希望的贯穿实用追逐将非常紧密的工作（追逐装满了管道，管道，炉子进气和排气等），并且必须穿过两个楼层来启动。

阅读制造商的文档，他们的评论突然跳出来 - 他们说，通常空螺柱腔将用于该装置的RA（返回空气）。突然间点击了，如果我用渗透到炉子返回导管的ERV陈旧拾音怎么办？这不是我经常描述的一个方案，但是当管道既新鲜和陈旧到炉子返回全部时，就没有存在的问题。

在ERV户外排气时，我有一个后面的阻尼器，所以炉子不应该在断电时向ERV建立后来。唯一真正的担忧是：

1) Obviously the furnace return grilles are not located in the same places you’d ideally place ERV return grilles- but, it would be better than how it is today (a naked pipe end in the basement), and I could possibly cut an ideally situated new return grille into the existing furnace return network (with a damper to flow match)

2）当两者运行时，ERV都必须对抗炉扇进行空气。This is what I’m really here to ask about- the ERV is pretty powerful, and the 4 large furnace return grilles have a pretty gentle flow today, so intuitively I’d hope the network can trivially supply an extra 100CFM without totally killing the performance of the ERV. However, while I have an anemometer & manometer, I don’t know the math to work this out to be sure. I know the balance of the ERV would change, but it’s already set to draw more fresh than it exhausts stale, and exhausting a little less stale some of the time would improve the thermal scavenging performance anyway.

有人会评论吗？炉内全部典型的静压下降太荒谬了吗？有没有考虑的Gotchas？谢谢您可以提供的任何输入。
