How to calculate time to heat a volume of air
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 … WebIf the air volume were infinite - we could assume that its ambient temperature is fixed (25 deg), approximate a natural heat convection coefficient (something around 7-10 watts W …

http://hvac-calculator.com/heating.php Web10 aug. 2015 · Start with a mass M of air in the room at T 1 Take away 10% of it and mix in (well) another M/10 at the lower temperature T 2. Heat lost from the warm air = heat gained by the cold air. 0.9M X SH X (T 1 -T final) = 0.1M X SH X (T final -T 2) SH is specific heat of air. The SH's and the M's cancel out so 0.9 (T 1 -T final) = 0.1 (T final -T 2)
