Why does this new AC unit say minimum 12m2?

[Znerken]

Wondering about purchasing this for my guitar room, as I hate when it gets too hot..

Looks super easy and great, BUT in the manual it says minimum 13m2 room size?

I can't get the links to open for me. But 13 square meters equals about 140 square feet.

13 square metres.

A metre is just over 36" or one yard so your room or area should be a minimum of 14' x 14' or 196 square feet. I'm from Canada, eh!

I'm not sure what you're asking. Are you looking for a conversion from square meters to square feet?

On page 6 it says "Appliance should be installed, operated and stored in a room with a floor area larger than 12 m2"

That's roughly 3 meters x 4 meters = 12 square meters, or roughly 9 ft x 12 ft. (Actually at 10.76 sq feet per Sq meter it's 129 square feet = 12 square meters)

BTW, if you type "square meters to square feet" into google, a conversion tool will be displayed.

My question is what happens if you use it in a smaller room? I have never seen a minimum, but always a max m2

If it's too big for the space, it'll cool the room down quickly without removing much moisture, so you end up with cool, damp air.

Even with the door in to the room open?

Delete......I think CMD might have it. And it might cause the unit to short-cycle, which isn't very efficient.

The minimum square footage should refer to the total space you're cooling using that a/c unit. If your door's open, then the total space you're cooling is larger than that one room.

Even though it says "floor space"?

The room gets like 26C in the evening, so cooling it down to 20 should
make it run for a little while?

Anyway, if I buy one and try, can it do anything harmful, or will it be fine? All guitars are in case when not played, cases and room has humidity sensors. Also have a room humidifier

Instead of square feet, shouldn't this be in cubic feet to take into account ceiling height?

Put another way if your ceiling is of typical height don't worry bout it.
If you have unusually high ceilings, factor that in.

More volume would require a larger AC unit, but I have no idea how to do that math.

I guess the manufacturer assumed it is a standard constructed house with 8' walls. On the load factor on the unit, how well is the space insulated? Is the outside wall in direct sunlight or is it shaded? How much glazing... on and on. Almost would cause the customer throw their hands up in the air and look for a box that said (good for around 160 sq ft).

The ac unit will stay on for a longer period of time if it was dropping the temperature down from a higher temperature. But once at temperature the unit will have a shorter on-off cycle. If it has to condition more air from the rest of the house then it will stay on rather than cycle. Probably easier on the unit than having it cycle.

So a 10m2 room with the door open is okay?

I live in Scandinavia, so our houses compared to American once for example are totally different. The room it will stand it is in direct sunlight for pretty long, that's why it gets crazy warm. 26 Celsius inside is way too hot for a Viking :-)

I would call the manufacturer as it is a bit different air-conditioner. Additionally, I see no exhaust hose to exhaust the warm air from the room. As you asked, I don't see it causing a problem if you use it in a smaller room.

There is. You just use it in the window, check this video https://youtu.be/a97Qk7_30RU
