RE: [EnergyPlus_Support] Economizer-Outside air

If you want to check the air flow rates you could report the variables:
?system node Temp? and ?system node massflowrate? in the appropriated nodes
(input and output of the zone nodes and of the outside air system).

Asunto: [EnergyPlus_Support] Economizer-Outside air

 

Hello,

I am trying to simulate an office building with an air system and getting
the most of the free cooling available through the use of the economizer. I
have set the minimum of outside air per zone to acomplish with the indoor
air quality standard regulations, so the outside air varies from that
minimum quantity to the maximum needed to meet the cooling load when outside
conditions are appropirate.

But, when i ask for the Zone Mechanical Ventilation Total Volume of Outside
Air, that amount is the same that the output for Zone Mechanical Ventilation
Volume Flow Rate. My question is, how can I assure that there is some return
air flow? Because it seems the system airflow is always outside air with no
return rate.

Thank you,

Carmen Herrero.
