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?
