DOAS issue
we have failures in some application engineering in DOAS application. The system is consisted of metal cooling panel(manufactured by our own) and DOAS unit. The cooling panel occur condensate in the hottest days in summer. our boss said the DOAS unit is without enough dehumidifying capacity. i think there maybe the possibility as follows:
# cooling panel actual capacity is low than designed value
# the hottest days beyond the design consideration
# system match is not good
# control method cannot prevent the condensate happen
i'm new in this field ,pls advice.
thx

Re: DOAS issue
What is a DOAS unit?
After editing I found via Google: Dedicated Outdoor Air System.
So an air handling unit? Am I correct?
In that case, are the metal cooling panels in the ceiling, a ceiling cooling with tubes mounted on it, mounted horizontally?
Have a look here then, great paper I got on my computer and it's still working.

It's better to keep your mouth shut and give the impression that you're stupid than to open it and remove all doubt.
