[Equest-users] Exhaust fan

[Nick Caton]

A simple approach is to ask "where is the exhausted air coming from?"  In the case of a restroom, typically the answer is the corridor or occupied space that it opens to.  Specify your exhaust quantity/scheduling in the corresponding zone.

Problems may occur in simulation however if your exhaust quantity exceeds the supply air to that zone however (more likely an issue for a kitchen), in which case you can extend the concept by "spreading" the exhaust quantity among other ancillary zones which are served by the same system conditioning this air to be exhausted.
