[Equest-users] design flow input vs. SV-A supply flow reporting

[Matthew W. Higgins]

Depending on your system type (VAV) I've found that you need to ensure your Min and Max flow ratios are set at 1.0 for each system, if appropriate. While the system sizing ratio is one thing, flow ratios are another.

But maybe you've tried that already, I don't know...

Carol:

I am having the same problem with airflow almost double from what I specified.  I tried the altitude correction and that did not help.

Does the zone air flow and exhaust rate take preference over the fan flow parameters?

Thank you,

Paul Diglio

Not stupid at all, If you have your altitude set to anything but 0 eQUEST will adjust your cfm accordingly. I always go in and set it manually to zero. I think it reads what it is off the weather file.

They say no question is a stupid question.

Why is my zone level supply flow cfm reported value in the SV-A report
higher than my overall design flow (ASSIGNED-FLOW) value? The
system sizing ratio is set at 1.00 (default).

Thanks in advance.
