RE: [EnergyPlus_Support] HeatExchanger:AirToAir:SensibleAndLatent





Dear Jose,

As the message indicates, the airflow through your HX is less than 50% of the nominal flow, probably when your economizer control allow minimum airflow.

The only solution that I know (and can remember) is to:

1.       Create an air loop (air handler) with no HX

2.       Place add a zone heat exchanger in the zone with constant airflow

This is not a very good solution for most situations!  Apparently the HX object has some limitations…
