Hi all,
Can we model toilet and kitchen exhaust fans in equest???
I tried to model it but the toilet and kitchens are unconditioned space so equest not giving any option to model this. there is any other way to model it or any other method for inputting the fan power and cfm in these spaces?
Any help would be greatly appreciated.

Thanks in advace

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.

Hi Ritu,
I think you can use the air system "unit ventilator" instead of exhaust fan system for the equal electricity consumption purpose.
