CFM Round up

1 post / 0 new

Wouldn't it be nice to just have the software round up the cfm's to the nearest ten? I've been asked numerous times why the cfm's do not match what is on the space/system output. Also there's this scenario...I'm modeling a fan coil unit or heat pump...who actually specifies a rheostat to get within 5% of the airflow your loads desire? These types of equipment only come with 3 fan speed settings lo/med/hi, so when the Space requires 96cfm and the equipment can only go as low as 185cfm on low-fan speed, why can't we model what the equipment is actually doing (cycling more)?
