You're confused with the units (and imperial units don't help). I already gave you the number: 1362 W/m
2 (high in the atmosphere). When calculating in watt, there's no reason to use BTU (or even joule). You took a unit of energy per day, and incorrectly converted that into a unit of power.
To start: 1 BTU
/h is 0.293W. When you forget the "per hour", you'll end up with a 24 times larger number per day. So it would be 33.291kW
h/m
2/day, or much simpler: 1362 W/m
2.
ya, a lot of that is lost along the way, but really, 0.25mw is not a lot as far as ambient is concerned
Let's call it 0.25MW.
have you ever walked next to a hotel or a large building and felt that it was "strangely warm" in the street? ya standing on the exhaust side of the HVAC or near the external ACs units will be too hot, but just by walking around, it would be hard to tell if the building is consuming 1mw or none just by the "feel of it".
Aren't those exhausts usually at the roof of large buildings?
what happens when you put 20 patio heaters inside the house and walk outside, are you still going to feel the heat? probably nothing much unless there is enough airflow forcing that heat to your direction
Correct. And you're blowing all this heat out.
I have personal experience walking in and out of mining farms as large as 2MW, it's only warm at the exhaust side because heat is being pushed outside into that direction, walking around the other 3 walls you feel nothing.
So my concern is unnecessary. I haven't been in mining farms, I've been in (very big) power plants though, but they used water cooling or cooling towers.
We don't have the ACs in place yet, the noise is coming out the wall and more so from under the door, but sound travels in all directions so it goes through everything at different levels, there is at least a 20db drop between door open and close, but generally, it's not close to as quiet as we need it to be.
Have you considered acoustic wall insulation (
see Dutch webshop)?
