Re: [EnergyPlus_Support] different air flow for heating and cooling systems

["Michael J. Witte" <mjwitte@xxxxxxxx>]

FURNACE:BLOWTHRU:HEATCOOL operates with a single flow rate for both heating and 
cooling.  You must model two systems, one for heating and one for cooling to 
have different flow rates.  Because a given zone may be served by only one AIR 
PRIMARY LOOP, the second system must be a piece of zone equipment, such as AIR 
CONDITIONER:WINDOW:CYCLING or UNIT HEATER.
