Why does Carrier HAP calculate ventilation load relative to exhaust air temperature?
Why does Carrier HAP calculate ventilation load relative to exhaust air temperature?
(OP)
I was reading the help file that comes with Carrier HAP and it mentions that ventilation load is calculated relative to exhaust air. Whenever I do hand calculations, I calculate the outdoor air ventilation load by taking the delta T between my outdoor air temperature and my cooling/heating coil discharge temperature. Have I been doing it wrong?
I have attached a screen shot of the help file for people to read.

This load is is not necessarily what your coil will however, as you rightly point out the air is only raised/lowered to the coil discharge air condition.

How much heat does ventilation air add to the SPACE? It's a function of the outdoor conditions and the space conditions.
