Re: [EnergyPlus_Support] vents

["Joe Huang" <yjhuang@xxxxxxx>]

Mohit,

If the self-regulation of the inlet vents is due totally to natural forces I
would model them as COMIS Openings.  There is a problem that at present all
COMIS Surfaces must be associated with a Heat Transfer Surface or
Subsurface, so you would have to define a fictitious window of the
appropriate dimensions and set its heat transfer and solar properties to 0.
Also, make sure its location, especially its height (Z) relative to the zone
that it serves, are input correctly.

> hi:

inlet vents will be on different floors, they are designed to provide a
relatively constant flow rate over a range of air pressure differences due
to stack effect and external wind conditions.
