Re: [EnergyPlus_Support] Single Duct VAV no Reheat

[fred buhl <wfbuhl@xxxxxxx>]

Diane,

The primary input is 1420 CFM. To obtain air changes per hour multiply 
by 60 minutes/hour and divide by
the zone volume. In this case air changes per hour is the derived variable.

The 1420 CFM is the "Maximum Air Flow Rate (m3/sec)" parameter, but how do you model 7.1 air changes per hour? Or, is this a dependent variable, and it is not necessary to model 7.1 Air Changes/hr?
