Dear Jeff Thornton,
Many thanks for your reply!
Do you mean we must buy TESS HVAC Library for TRNSYS?
Is there no other methods to model exhaust air/fresh
air Heat Recovery Ventilation System in Simulation Studio? E.g. using Equation
or other component/Type in Simulation studio?
Many thanks in advance!
