配置Minisplits
嗨伙计,
[编辑9/25:与本地所有安装程序进行检查,没有人会导致单元]
我们在6区(新罕布什尔州北部)中有一个1200平方英尺的单层(地下室)。它建于1950年代,已通过绝缘升级(R60阁楼,2×4墙壁中的玻璃纤维吹,泡沫边缘和地下室)和空气密封。鼓风机门为3.87ACH50,手动J热负载〜35,000BTUH(附件)。
We would like to replace our old oil boiler. We heat primarily with a woodstove, but want something that can keep the pipes from freezing if we leave in winter, and supplement the woodstove for convenience. On-site solar is a possibility in the next 1-2 years, so we’re interested in electric solutions.
The best local installer recommended a pair of Fujitsu ASU18RLF units indoors, each with a 18RLXFWH outdoor unit, both in the main kitchen/living area. His alternative was to put one in the main area, and a multi-split covering the bedrooms.
在我看来,理想是覆盖卧室的管道单元 - 但我所在地区没有人安装管道单元。
关于将两个单元放置在主要区域而不是多拆分的想法?根据我的阅读,我将远离多阶段。对于卧室的温度差,我们很满意 - 但没有在一个空间中读到两个单元的性能问题。
Thanks,

道格,
I'll give your post a bump.
在我看来,当与净计量太阳能电池板配对以供锅炉供电时,电动锅炉只有有意义。
如果您需要/想要冷却,那么迷你拆分将是一个不错的选择。
我认为,如果您将风扇放在窗户上,并用一些烟雾从香棒中吸烟,您可以找到很多泄漏,并且比3.8 ACH做得更好

Thanks Walter
我(可能)在杰克逊(Jackson)的南部,我们有一个两个楼层1300以上的平方英尺“漂亮的房子”,我们在一楼有一个迷你拆分(三菱FH12NA)加热/凉爽。地板和房间之间存在一些温度差异,但是考虑到一个相当小的单位,通常可以很好地效果。我们在卧室/浴室中有墙壁加热器以备用,但很少使用它们(仅当预计会达到-20F时,几乎只有在夜间临时)。我只是一个大量参与建筑物的房主,所以我不是专家或顾问,所以请记住我的建议!
我建议您使用冷却/除湿。
If you primarily heat with wood and add the mini split(s), putting a lot of effort and money into electric baseboard or cove heaters seems overkill. If you feel like you need to do that, I'd look into these 120v plugin wall heaters from Convectair as they're easy to install and easy to take down if not needed:

For mini split sizing and placement, I've often seen advice on GBA that putting a single unit in a bedroom can sometimes be overkill, but maybe Bedroom 1 would be a good candidate for the small Fujitsu unit. The options given to you by the installer may be ok or great, I don't have enough expertise to judge that, but you could consider starting with the 18RLXFWH/ASU18RLF combo in the main area, and then add on after you live with it for a year.
如果可能的话,我还建议将室外装置安装在高架基座上,而将室外装置安装在外墙上。这并不可怕,但是我们发现,当在恶劣的冬季条件下努力工作时,室外单元的噪音/振动可能会很烦人。
谢谢布莱恩。是的 - 我们向北更远。我没有看到对流加热器,我会考虑的。我们几乎肯定会在主要区域做18K,并且可以按照您的意思来做今年的情况,以了解它的发展。我喜欢卧室的管道单元的想法,但需要找到一个体面的安装程序。感谢您在基座上的提示!
我建议使用15K,较低的调制,而不会在容量上太多差异。
谢谢凯尔,我没有意识到15K有更好的调制。我会查找规格。
笔记that lower modulation doesn't mean better modulation - it could easily provide lower efficiency and less dehumidification.
好点子。谢谢乔恩。
