I just want to check what the Fixed Air loss is considering when running a Heat Loss calculation in Load Calcs.
Fixed air @ 17C enters a room with 21C set point at 40.5 L/s.
(40.5 x 1.23 x 4) = 199W fixed air loss
However my room calc is coming out at 348W.
Could anyone let me know what other things are considered in this Fixed Air loss?
Many thanks for putting these queries forward, can you please share your project through the link here so that I can have a closer look?
FYI - I am only looking at the zoned areas on the 3rd floor - so have just included two floors below and set them at same temps so no heat losses.
these below factors are considered while calculating Heat loss.
and the infiltration formulae implemented as below:
