I need to understand this properly I think maybe it will explain whats happening here I don't understand how I get a smaller delta T stale - exhaust than between inlet and fresh, if the temperature boost is a result of heat being exchanged? Checked for leaks and instrumentation. I saw similar phenomenon with the small scale experiment, strange. I need to know why. Given: Q l  = h we  ρ q Δx / 3600  Is it  Δx = difference in  humidity ratio  ( kg h2o /kg dry_air )   causing this reading? Seemingly double the  ΔT  inlet to fresh than stale to exhaust.
