Modelling balanced ventilation with heat recovery [EnergyPlus]
Hi!
I am looking to model a balanced ventilation system with heat recovery, but without linking it to a heating or cooling system. The ventilation system should simply consist of a supply fan, extraction fan and a heat exchanger in between the supply and return ducts to create the heat recovery system (i.e. the heat from the return air is used to pre-heat the supply air).
Looking at the HVAC in the documentation, it seems that all ventilation systems must either be linked to a heating or cooling system, or have no heat recovery at all.
Thanks in advance for your answers!
@Gijs_WE what simulation tool are you using? Please mention it in the title or body of your post, as well as add a tag so that others can provide better help.
Also, if you can upload your model to Google Drive, Dropbox, etc. and then share a URL for others to download, that would help others provide better solutions.
Finally, can you clarify if there is any outdoor air mixed into the supply air? It sounds like you have 100% recirculation (all supply air is return air, so no outdoor air is mixed in).
@AaronBoranian There is outdoor air mixed into the system, in fact all supply air is outdoor air. Only it is preheated using heat from the return air, which is dumped outside of the building (no recirculation). Thanks for your comment!
