你好，我正在对我在圣布鲁诺的家进行大改造，邮编是94066。我的架构师没有在计划中指定ERV系统，理由是它不符合代码要求。但我听说它们可能是有益的。我还没有开始施工，所以有时间修改设计。1)你建议安装一个吗?2)如果是这样，有什么建议吗?或者你推荐的特定品牌/系统?
We always recommend installing an HRV or ERVin any home with a heating or cooling system. Homes need fresh air for durability and humans need it for health. So if you are either heating or cooling a house with no HVAC system you are left with one solution, opening windows. At that point, air you paid to heat or cool is ejected from the home with no energy recovery.
Here is our page onChoosing Between an HRV and an ERV.
As for brands, we have used Van EE, Venmar, Lifebreath, Zehnder and other brands in our builds, we even used this system here that may be of interest –Lunos Ductless wall insert ERVs. I would see what is available regionally and base your decision on warranty, availability, cost, and its rate of efficiency, that information should be available through any brand website. But for sure I would install one if I were you regardless of what code says. Building code means well, but isn’t always your friend and doesn't always give the best advice : )
