Hi all:
in my modle, in DOAS, I choose DCV return sensor, min fresh ratio=1, and not defined sum air volume of dummy zoon. i think the air number will vary with people number , but not. so who can guide me how to setup parameters so that air quantity change hourly. thanks
BEST REGARDS

In the current version of eQUEST (3.64), "OA from system" isn't really
DOAS -- it is a temporary work around that has not been removed. I
understand it is high priority to fix in later versions. At present,
all that happens is the OA temperature for the borrowing system is set
to the return air temperature of the lending system. So, the air
volumes aren't really addressed -- although the air volume of the
lending system does get set up if the borrowing system OA volume is
higher. However at present (to my knowledge -- please correct this
those who know) the lending system does not look at the hourly OA values
so its volume will not change even if you turn DCV on for the borrowing
system.
