Locating Bathroom / ERV Exhaust
你好，
我正在建造一所房子，希望与R40墙体绝缘保持1.0痛苦。我在卑诗省温哥华气候区4。
我根据迄今为止的各种因素决定使用ERV + Dehumidifier（如何导管我尚不知道）。
The purpose of the ERV is to help maintain the humidity at 45-50%. I have found in the winter in my leaky home currently with the heat on the humidity can be driven down into the RH 30% at 23C. During August for example humidity can shoot up to 60% at 23C – this is the purpose of the dehumidifier.
Now my main concern is whether the ERV should exhaust from the bathroom and laundry room. Or should I have bathroom fans separately and the ERV exhaust from somewhere else?
The reasons for this: the bathroom moisture I don’t want to come back into the home through the ERV; also, this will help keep the ERV core cleaner; and this would avoid having to “boost” the ERV cfm to the whole house just to clear out 1 bathroom for example.
(n.b. my home will have 2 floors, 4000sqft, 5 bathrooms)
我的主要挫折是由于在墙上有一个6英寸孔的浴室排气的能量惩罚。
有什么想法吗？

我看着alde多端口排气扇that handle 4 baths with one opening. Each bath would have a backdraft register, and go into its own inlet on fan itself. There is one outlet from the fan that exhausts outside. For air balancing, Use a makeup air damper that opens when an exhaust only system is running, such as a bathroom fan exhaust, clothes dryer or kitchen fan. Not a perfectly balanced system but better than most.
排气渗透应密封良好，刚性金属管道应具有乳香。排气应倾斜，因此任何冷凝物流向外部。有些人在你获得凝结的情况下使用PVC管道在最后4英尺处使用。
That's interesting. Thanks. Will look into it.
在一个紧的房子里，我不会使用浴室粉丝，因为那么你必须弄清楚一个策略来提供化妆空气。否则，您的风险抑制房屋或您的粉丝不会与空气出局有效。这在我看来，这比过度透透了房子20分钟。此外，在冬季除湿，往往比通风更经济。
一个解决方案，如果您担心促进整个系统，是ALDES ZRT-2套件和CAR3 / Modulo调节器（不知道2之间的差异）。CAR3是气流调节器，其将提高其静压以在空气压力增加时调节空气流量。如果您将其设置为10 CFM，即使您提升了整个系统，您将始终收到10个CFM。下行是需要的0.2升压力。在我看来，它仍然优于过度透水。
The ZRT-2 is a damper that is either fully open or otherwise acts as a regular CAR3 regulator. In normal mode, the air goes through the CAR3 and you can set it to a whatever flow you like like 10 cfm. When you hit the boost button because you need extra airflow to handle the moisture, it will open up the damper to circuvemt the CAR3 and boost the ERV speed. If you have CAR3 installed on all your other ducts, then the airflow will only be boosting in the room with the damper opened not the other ones. Of course, the system static pressure in the other branches will increase so your ERV will have to work a bit more to push the air out but it's better than overventilating.

I don't know how things are in BC, but here in Quebec it's hard to buy these parts from a store. They only want to sell them to licensed contrators. Some US websites sell Mr Modulo online though.
BTW，Venmar（和Vanee）现在销售高速增长的HRV / ERV。这可能有助于您的除湿器管道问题。我打算在我未来的房子里用一些CAR3 / ZRT-2使用。希望他们会在一起工作。:-)
谢谢。Venmar单元看起来很好。
Best of luck with your build.
哈欠，
似乎有一个错过的机会，可以使用它的设计中省略的浴室均衡，能量智能通风。这并不是说你的担忧是毫无根据的，只是我的看法。考虑到4,000个SF房屋有很多体积，以淡化早晨淋浴的回收水分。当然，它会增加除湿负荷，但它会比独立的排气风扇相当多于独立的余粉丝，并且在外壳中有10个额外孔，从略微不平衡的通风中增加压力？
我不是ERV的专家，但我想知道是否有任何用于焓轮速度或部分恢复旁路的住宅单元，类似于这里描述的内容：

I realize that's at multifamily scale but they're describing the same problem. It sure would be nice...
是的。同意。浴室的旁路会很棒。
