Advice for keeping snow off a minisplit?
Apollo S|发布了GBA Pro Help在
As I am getting for another bad New England winter, I clearly remember my last one, when we just got minisplits installed. It was daily duty to shovel them out. One installed on the North side would get bunch of wind-swept snow off the roof above and so would the one on the East side.
Unfortunately, I did not know it was possible to mount them on the wall, so they are sitting on concrete pad HVAC people installed it on. Maybe I wold put lattice on the side where prevailing winds are from and try to keep snow off it that.
我正在考虑在他们两个之上建造棚屋屋顶。有什么想法吗？建议？经验？
Shed roof would be removed during warm season.

阿波罗，
咬住子弹并花钱将MiniSplit安装更高，使用壁挂式支架或某种类型的高架支架。
A shed roof above the unit is certainly a good idea, as long as there is enough clearance to ensure that air flow is not restricted.
格子，围栏或棚屋不是如此好主意，因为这些特征可以限制空气流量并降低单位的效率。在那个部门轻轻踩踏。
There are lots of articles and Q&A threads on this issue at GBA. Here are a few:

请将我推荐给商业产品或计划，为我的两个三菱Miniplits为雪和叶保护的屋顶
阿波罗，
There are lots of photos online. I can provide a rating of various solutions.
This unit is too near the ground. The lattice may be the worst of all worlds -- not enough of a barrier to stop wind-blown snow, but enough of a barrier to interfere with air flow.
.
The roof was a good idea, but again -- the unit is too close to grade.
.
This one is elevated -- that's a good idea -- but the enclosure is a terrible design, because it is much too restrictive of air flow.

Nice roof, excellent air flow -- but much too close to grade.

Roof is a little stingy, and the unit is too close to grade.

Download the manufacturer's installation manual and study the clearance distances to objects, walls, etc. and add 50%. The shed roof approach works and is essential if the compressor unit is mounted in the path of eave cornice/ice-dam falls.
The shed roof in Martin's response #6 looks about right, even though mounting it at dead-grade level on an air-conditioning condenser pad is asking for trouble in snow country, even with a pretty good roof. Notice how much digging was required to keep it clear in response #2.
在伍斯特的深度能源改造上方的压缩机安装在45-48“上面的等级上面，几年前Ma在去冬天的雪跌期（大多数落在5周）的雪跌期间很好，无需挖掘（无论如何都是迷你分裂。）
I was thinking about #6 actually. These are Mitsu MXZ-2B20NA units.
Goal is to mount them on the wall next year, but I need a solution for this year. I hired an architect to make some changes to the house and mini-splits condensers may end up relocated anyway.
Do need to put something over them, because snow and icicles fall on them from roof above.
BTW, clearances required in this unit seem very low
