[EnergyPlus_Support] Re: Zone Sizing and outdoor air



Dear all, 

 

i entered the required amount of Outside air into the Ventilation object.
The following is a sample from the .err

 

Warning ** PURCHASED AIR="ZONEG04AIR" has outside air specified. In
PURCHASED AIR simulations,

   **   ~~~   ** the outside air flow may be limited by the supply air flow
rate at low load conditions. Do NOT use this option

   **   ~~~   ** for annual load comparisons.  Instead, introduce outside
air using INFILTRATION or VENTILATION objects.

 

Severe  ** PURCHASED AIR outside air mass flow rate reduced due to low
supply air flow requirement

   *************  **   ~~~   **   This error occurred 3388 times.

   *************  **   ~~~   ** PURCHASED AIR=ZONEG04AIR

 

Can I use the zone sizing .Zsz.csv results?

 

Why the Severe error occurred thousands of times though the zone sizing
result is 4 time step/hr  x 24 hr?

 

Sincerely

ooi
