Martin,
您不是您喜欢的特定干燥通风口插座吗？
Was it the“Heartland”?

Lucas,
The Heartland is a good one. That's the one I have on my house. It's a pain to disassemble and clean, however.
Another really nice one is theSeiho dryer vent termination. It's made out of stainless steel.
Martin,
Thank you.
我最近在工作中使用了Seiho SB，如果您必须看或经过它http://www.seiho.com/product/sfb/sfb.html

I have installed several of the Heartlands over the years and they do work very well if they are cleaned regularly (at least once a year). Have you thought about makeup air for the dryer? I have never tried this, but what about installing an additional Heartland on the interior, somewhere near the dryer?? It should open automatically when the dryer creates enough negative pressure...
或者，如果您正在运行HRV，则可以在干衣机运行时让它运行不平衡...
Garth that's an interesting idea...
My plan to this point has been to frame a sort of "airtight" closet around the washer/dryer and weatherstrip the closet door(s)...
What I haven't decided on yet is how to best provide make-up air to the closet and (since the washer and dryer don't stack) what kind of door I could use that could be weather-stripped and would be wide enough access both machines comfortably.
我开始认为，要说服我的妻子我们应该出售我们的烘干机将会减少工作。

I can remember bringing in frozen laundry from the outdoor clothes line when I was a wee lad...I'm with your wife on this one.
如果被动化妆通风口在烘干机附近的某个地方，我不认为需要“密封壁橱”。在一个非常密封的房屋中，它只有在干衣机运行时才能接收到外部空气，并且可能会加快干燥过程，因为传入的空气的绝对湿度水平非常低（在冬季）。
Garth,
You're right that I'll need to come up with a more creative argument than hanging our clothes on the line in winter.
Maybe an indoor drying closet...
As to the "airtight" closet for the dryer...
我担心在干衣机运行时加载木炉时烟雾溢出。
R. Riversong提倡Weatherstrestrandry Room的门，但这一定意味着洗衣房有点“紧”，否则没有太多要点...
I wonder if locating a source of make-up air next to the dryer is sufficient?
也许里面没有化妆空气的不那么紧密的壁橱就足够了吗？
Lucas
My thinking is that the air that is exhausted by the dryer will cause a negative pressure, and that the "replacement" air will tend to follow the path of least resistence. By providing a 4" Heartland type vent hood for make-up air on the "inside" of the laundry room, you should not experience any problems with the wood stove etc. The stack effect should keep the draft in the stove pipe going and would reqiure some significant negative pressure to reverse it.
RR's advice about weatherstripping would indeed make some sense if there were no source of make-up air nearby (but the dryer has to get air from somewhere). BTW, are you planning an exhaust only ventilation system, or HRV??
Garth,
我正在计划HRV。我很久以来一直是壁橱排气风扇，但我认为这是更好的选择。
The idea of the "airtight" closet was to help ensure that the "path of least resistance" would in fact be the source of make-up air (also located in the closet).
Thinking about pressure dynamics sometimes makes my head hurt. There are so many variables.
Lucas
I am certainly no expert on pressure dynamics, but for what it is worth, here is what I would do. Forget about a make-up air vent for the dryer. Just make sure there is a fresh air vent from the HRV somewhere nearby, and the HRV will supply the needed air (it will simply run unbalanced while the dryer is on). This has the small advantage of some heat recovery...
Your wood stove should have its own dedicated combustion air supply, and therefore should not be affected much by the intermitent negative pressure events.
Maybe there are some actual experts out there with some good advice????
Garth,
我从未听说过一个如此紧密的房子，以至于干衣机被空气饿了。几乎所有房屋都应该有足够的裂缝，您不必担心。
Passivhaus制造商经常安装冷凝干衣机，但原因并不是传统的干衣机会饿死。原因是他们不喜欢这一事实，即干燥机不运行时，排气口会在两个方向上泄漏空气。
这是一些简单的测试：
当您的干衣机运行时，您能感觉到排气管在房屋外部留下终止吗？这意味着它可能正在工作。如果排气很弱，请检查管道最近是否已清洁了棉绒。
Second test: do your clothes dry in a reasonable amount of time? (Again, check the filter and duct for lint before assuming another problem exists.) If so, your dryer is getting enough makeup air.
Just to clarify:
我不太担心火炉燃烧时燃烧的炉子关闭，只是在干衣机跑步时打开装载的门时。
The stovepipe will go straight up about 25' from the stove to the cap and most of this length is in conditioned space so the draft should be quite strong...
But if a strong stack effect is present and then I start exhausting 250 CFM (I think this is about an average rate for a dryer) out of the basement - and no make-up air is available - will the chimney draft still be strong enough to prevent spilling smoke into the house when the stove door is opened?
还是我过度思考？
Ideally, I would like to limit the number of envelope penetrations to the bare minimum possible so if make-up air isn't required so much the better.
Lucas,
听起来您更担心木炉可用的燃烧空气，而不是担心烘干机的化妆空气。如果我的猜测是正确的，则通常的解决方案是为您的木炉提供管道燃烧空气。
Martin,
有点...
炉子有自己的管道空气供应，从平板下方出现，因此炉子应在门关闭时良好。
我只是想知道，在没有化妆空气的烘干机时，打开木材的门是否会让我的脸充满烟雾和灰烬。
Lucas,
我认为您正在考虑这个问题。
Martin,
我也开始这么想。
感谢您的现实检查。
反思是一件好事……我打赌that with Lucas's attention to detail, that his home is likely to be "very" airtight!
卢卡斯,我认为你会inve的家伙nt the two-pipe heat-exchanging dryer intake/exhaust system. Motorized damper at the wall cap? I'll buy one from you.
Lucas,
I'm with you on this one. For my hot water heater I went with a direct vent unit that gets combustion air from the outside and blows the exhaust outside.
我看着楼上洗衣房的风气，既有“绿色建筑”和隔离原因。在调查了干衣机的化妆空气之后，没有做到这一点，主要是因为它意味着穿过屋顶或屋顶谷附近，而我不去那里。我确实使用了电动机代替燃气干燥机，因此我不必担心燃烧气体。
A couple of points:
代码很可能需要带干燥机的房间上的通风口。代码通常意味着整个房间的化妆空气或通风孔和房间高。阅读干燥机安装手册，应该告诉您需要多少平方英寸的通风孔空间。
I was going to use a motorized damper as well. The better ones have rubber seals.
One of the issues with makeup air for a dryer is the same as makeup air for a powerful kitchen vent hood -- you get cold air in the winter (not great for drying clothes or for those hanging out in the laundry room or for the water connections to the washer if you're bringing in freezing air) and you get hot humid air in the summer. This raises all sorts of house design, insulation, water vapor, and possible mold issues.
I also wondered why they don't make "sealed combustion" type dryers that bring fresh air from the outside and blow the exhaust out. The main problem is that most of the air isn't for combustion, and in an electric dryer none of it is for combustion. Instead, the air is for drying the clothes! I'm not sure you want to do that with freezing winter air (think freeze-dried clothes -- just add water before you wear them :-) ) or humid summer air. The exhaust heat exchanger may be OK in the winter but not in the summer. But maybe it could work.
David,
轮到你了 ;-）
威廉，
感谢您的观点。关于代码要求，这是一个很好的
