Re: [EnergyPlus_Support] about the heat recovery system



The example file HeatRecoveryElectricChiller.idf shows how heat can be 
recovered from electric chillers. This example file does not show how to 
use the Heat Exchanger:AirToAir objects. Several other example files 
show how to use the air-to-air heat exchanger. These are 
CoolingTower_VariableSpeed, DesiccantCVRh, DesiccantCVRhZoneRHCtrl, 
DesiccantDehumidifierWithCompanionCoil, HVACStandAloneERV_Economizer, 
TermRhGenericOAHeatRecMinExh, and TermRhGenericOAHeatRecPreheat.
