[EnergyPlus_Support] Purchased Air Question

["energypluser" <energypluser@xxxxxxxxxxxx>]

Dear all

When I looked the user news of building energy simulation in 
Jul/Aug,2004,I found a statement about the purchased air coupled with 
outside air. The asker has a question about the difference between the 
purchased air total cooling energy and the purchased air sensible 
cooling energy.
The answer in the file explain why the total cooling energy is less 
than sensible cooling energy when the purchased air is mixed with 
outside air. But the following sentence in the explain section makes me 
confused:
"If the purchased air flow rate is less than the outside air flow rate, 
then the purchased air flow rate is used and is 100% outside air"
Can you explain it for me?
Thank you in advance.
