Through the wall HVAC - which one to choose?

[Johan]

Hi everybody!

Is there someone out there who can recommend an HVAC of this type?

In Sweden these HVACs are not at all as common as in the States. I talked to the leading ventilation company over here, and they had three different products to choose from - the one with the highest fresh air supply provides a mere 10% of the oxygen needed.

So, has anyone used the "through the wall-method" with an air chamber, described in Rods book (pages 131-132)?

Can anyone recommend a system that provides 100% of the needed oxygen, dehumidification and enough cooling for a live room, as well as heating when the studio's not used. Perhaps without being too noisy?

My single-room studio is 25 m2 + 5 m2 for the air chamber, takes a maximum of 4 people and produces a total of 3000 W/h of heat load at most.

Any help would be much appreciated!

Johan,

if you can't find units that will meet 100% of your needs - choose the unit that comes closest - and then supplement that with a seperate outside fresh air supply that WILL provide the difference - pumped into the chamber just in front of the through the wall unit to allow it to mix..

It isn't that deep........ you're just over thinking this.

Thanks, Rod!

I thought creating a separate fresh air vent might work! That is some seriously good news! Now I can finally go down to business and have this build wrapped up! Will post some pictures for everyone on this forum to see.

Bless ya!
