[EnergyPlus_Support] Re: model "Dry cooler" and "run-around heat recovery" in EnergyPlus?

["tjutw" <tjutw@xxxxxxxxx>]

Hi Richard,

Thanks a lot.
I will model the runaround heat recovery unit by using
"HeatExchanger:AirToAir:Generic model".  
What model should be used for the dry cooler?

Thanks,

Tj Ywh
