I have data concerning tests on a heat exchanger. Exchange efficiency is only sensible and it is presented for different conditions of the external air (dry-bulb temperature and relative humidity). I would like to model the effectiveness variations according to the external dry-bulb temperature and wet-bulb temperature. Is it possible? I'm using the object HeatExchanger:AirToAir:SeinsibleAndLatent
I see that in that object different effectiveness values can be inserted for different air flows, but what about the variation of outdoor air conditions? I read "Table 30. Operating Conditions for Defining Heat Exchanger Performance" in I/O Reference, but how does calculate EnergyPlus the exchanger effectiveness if the real conditions are different from the conditions that are written in Table 30?
With Regards
Francesco
