Dear all,
Could anyone please pass me some relative examples for Heat Recovery
ventilation system using a sensible heat exchanger model and a series of
equations and Type 33 psychrometrics models? Or please tell me where could
I find some relative examples?
Since I can not find any Examples from TRNSYS/Examples file for that. For a
beginner, it is too difficult if no examples.
Many thanks in advance!
Br.
