[EnergyPlus_Support] Re: HEAT EXCHANGER:AIR TO AIR:FLAT PLATE in zone equipment

["massimiliano_scarpa" <massimiliano_scarpa@xxxxxxxx>]

Hi, Brent.
I thank You for the quick reply.
Your remark is opportune, but I think that there is anyway an 
unitary equipment with the same target:  
it is the ENERGY RECOVERY VENTILATOR:STAND ALONE. It looks like a 
better structured and complete HEAT EXCHANGER:AIR TO AIR:FLAT PLATE, 
including the fans as well. 
This way, HEAT EXCHANGER:AIR TO AIR:FLAT PLATE seems to have no aim, 
in zone equipment.

I hope you'll enjoy the rest of your day

Max
