通风加热和冷却pH
一个被动的房子需要一个机械超大杯lation system and a heating/cooling system (Zone 5A).
What is the most cost effective method of achieving this? Since we will be putting in ductwork for the ERV/HRV system, it only makes sense to use this system to distribute warm and cool dry air, as opposed to having the ductwork and mini splits hanging on the wall. Also, we would have to condition (de-humidify or heat) the incoming air before it hits the heat exchanger anyway.
Zehnder Comfofond（http://zehnderamerica.com/our_products_categories/geothermal-heat-exchangers/) , or something like this (perhaps an air to air heat pump instead of geothermal) appears to be the solution. Are there other manufacturers that have similar systems? Are they as efficient or more affordable? Will this pre-conditioning of the incoming air be enough to keep the house comfortable year round? Therefore, no other heating or cooling would be needed?
我的被动房屋顾问将我带到了伊利诺伊州中部的“黑匣子”（Cerv）制造商。http://buildequinox.com/products/cerv/。有人使用过其中之一吗？这些成本如何比较？这听起来像是用于加热，冷却和通风的完整系统。
地球试管到预处前的空气肯定在纸上听起来像是一个好主意 - 非常简单，安装便宜，运行便宜 - 但是那种讨厌的霉菌潜力使我想使用其他解决方案。
Given that the black box and the Zehnder systems are probably quite costly, it might make economic sense to use a less expensive heat exchanger and mini-splits. This seems to be the solution for many of the North American passive houses. Is that because of costs? Product availability? Familiarity with the products installed?

史蒂夫，most of what you ask has been answered by yourself and here at GBA via blogs on PH homes. Visit more actual PH homes, and contact some of the more experienced PH builders direct if you really want to dig deep into PH.

There is no advantage to combining the ventilation with the heating &/or cooling systems, since ventilation needs occur with or without heating or cooling loads. In a super-high-R house with super-performance windows, ducted heating & cooling have little benefit, making mini-splits a good solution, using some other approach for ventilation.
In a zone 5A location cold-climate mini-splits (Either the Mitsubishi M-series " -FHxxNA" or the Fujitsu Halcyon XLTH series "-xxRLS2-H" ) make sense, since they are purpose-designed to work well at sub-zero F temps, and have rated output even at -13F/-25C and lower. Other heat pumps can have ice accumulation issues (and pathetic output & efficiency) at low temps below +5F/-15C.
DANA-感谢您清除我正在解决的机械系统问题。看来我将不得不找到HRV或ERV（我仍然不太确定哪个更适合5A）和一个迷你拆分系统。如果我足够隔离和密封，我希望能在1850平方英尺的房屋中逃脱一个单元。
My brother, in Ottawa ON, will be interested to see the models that you recommend for cold weather, too.
AJ - I have spent many many hours on the GBA website, and purchased every Passive House book that I can find, GBA is far better for acquiring knowledge. Most of the books have been next to useless with regard to building details and systems used - more like architect showcases.
I realize that PH cannot be "cookie-cutter-ed" but it would be nice if PHIUS would put together a distilled and detailed summery of what is being used in North America. I see that they have started with window manufacturers, but I would like to see more on how folks insulated under foundations/slabs, wall construction, window and door installation, mechanical systems, and barriers (tapes, membranes, foams and the like).
确实详细介绍的两三个好pH书籍仍然非常有限。这就是为什么我一直在这个网站上花费时间并提出一两个问题的原因。我有太多东西要学习，附近没有pH或pH组的例子（我目前位于德克萨斯州休斯顿的南部），尽管几年前我一直在乌尔巴纳（Urbana）参观过这样的房屋，而且我才知道该问什么。
South of Houston. Well that makes a difference. Humidity? Heat? Cooling season? Minor heating season?
PH我们，没有人在内，包括老板Katrin Klingenberg愿意让您走上您的道路？
史蒂夫。打电话给我的男人，让卡特林加入船。
对不起，AJ。我想我不清楚。我现在住在德克萨斯州，但将在几年内退休到俄亥俄州，我们将建立大多数DIY PH。那个DIY因素就是为什么我试图了解pH的各个方面的原因。
I have a PH consultant in IL but I am trying not to bother her too much until I have a satisfactory preliminary design, including floor plan, mechanical ideas, construction details and the like.
我无意在这里建造任何东西，下一个飓风可以将其全部撤走。另外，对于这个加拿大男孩来说太热了；-)

史蒂夫，
正如达娜（Dana）指出的那样，将通风与加热/冷却系统相结合没有优势。对于您的尺寸房屋，恢复EV90P应该很好地处理通风，并且可以消耗45瓦以下的通风。对于较低的通风速率和功率使用，请使用计时器类型控件的百分比。我计划使用一个浴室，将空气吸入其中，然后将新鲜空气输出返回到一个普通的走廊。迷你拆分实际上仅是为了加热/冷却单人间。即使使用被动房屋绝缘和密封，“私人”房间也会使用“点源”加热/冷却系统（例如迷你拆分）具有明显的温度差异。我的解决方案是在“壁橱”中找到迷你拆分的室内单元，以及5个“窃窃私语”风扇，以收集迷你拆分的输出，并通过地板下的简单管道将其移动到建筑物的周边拆分就开始了，带有“跳管”的回流道路，并在“壁橱”顶部开放烧烤架。“窃窃私语”的球迷非常安静，非常高效且聪明，因为他们移动了可选的空气，独立于导管背压。但是，风扇和控件在加热/冷却电源的使用中增加了约50瓦。
