(OP)
Hello All
Usually they use 400 cfm per ton, but this needs the delta T between suply ait temperature and cooling set point to be about 27F, so if the set point was 75F then the suply air has to ba about 48F
I know the suply air usualy is about 55 to 58 F
shall we have to go with this rule of thumb 400cfm/ton or go with program result?
Thanks
