[Bldg-sim] System 7 Min VAV setpoint

[Anis Ben Ayed]

Dear all, 

 

The VAV minimum set point for system 7 in Appendix G is calculated based on
(0.4 cfm/ft2). For some spaces this number is bigger than the calculated
design airflow based on 20F delta T. What should the VAV set points be in
this case? 

 

Example:

Room:    

VAVmin = 131 l/s

Design Air Flow = 84 l/s 

Fresh Air = 108 l/s

 

Thank you for your input,

 

Anis
