there are multiple ways of simulating that. You can use a simple heat exchanger or define your own function within an equation writer.
I generally call excell for flow rates and temperatures, but use the heat exchanger model for the air-to-air heat recovery.
In cae it does not work out, let me know. I can send you some example files...

Hey at all,
I am trying to simulate a building with a mechanical ventilation containing a HEAT RECOVERY (e.g. 80%). I can´t use Type 334, but i guess there should be a opportunity to work with a heat recovery by using an equation which contains the ambient and the room temperature. Does anyone has ever used a heat recovery without type 334 and know how to solve this problem??
I am thankful for any advice to simulate the heat recovery in TRNSYS.
Best,
Michael
