If the building is ending up around 70, that means I’m underestimating the exhaust quantity by about 2x. But then apparently the extra infiltration is only about half of the exhaust. So sounds like the errors cancel out and my initial estimate happens to be roughly right?
Thanks! It’s amusing that we had this whole discussion and the one commenter who knew what they were talking about got just one upvote :)
It sounds very plausible that exhaust is small relative to natural infiltration and I believe you that (extra infiltration) = 50% (exhaust).
In the other direction, it looks like I was wrong about 130 degrees and we’re looking at more like 100 (alas, googling random forum comments is an imperfect methodology, though I do feel it’s plausible that John’s AC has unusually cold exhaust).
