Web19 mrt. 2012 · Rob, The heat capacity of air at sea level is, on average, 0.018 Btu per cu. ft. per degree F. So the infiltration heat loss calculation is: [delta-T] x [ACH (actual)] x [volume] x 0.018, where ACH (actual) is the actual … Web12 jun. 2024 · To heat a given volume of air by a given amount requires energy. It would make sense if you specified a period of time for that level of power. Aug 27, 2013 #3 sromag 10 0 Thanks for the reply. As for time period, say 10 minutes - 600 seconds. And as I say, I'm not sure about the 0.005 watts answer. You're right, it seems a little incomplete.
