Hello experts,
I've been trying to calculate the sensible heat gain from a commercial dryer for the past two days but no positive results. Can someone here guide me on how it can be done. Thanks
Qs=cfm*1.08*(dt)
Qs=3600*1.08*(70)=272MBH bringing air from 70degF to 140degF, now if the discharge temp is higher, you will have less gain to the room, as your dT will be larger.
550MBH-272MBH=278MBH gain. See what the outlet temp is and you will have it.
Depending on the installation, the heat gain to the occupied space may be negligible. The body of the dryer will be in the back of house space where all of the combustion/make-up air is (can be) introduced. Cycle time of the dryer will impact things, but for worst case you can assume they are all running constantly.
