Hi Amin, When you link Type 399 to Type 56: If the surface 1 is facing “the air node”, then TB1 = Tstar (= NType 23: star node temperature of the zone) If the surface is facing outside, then TB1 = ambient air temperature If the surface is facing “user-defined boundary condition”, then TB1 = boundary temperature as defined in Type56 Regards, Seyedmostafa Mousavi Renewable Energy and Energy Efficiency Group The University of Melbourne, Australia

On Behalf Of Amin HADDAD via TRNSYS-users Hello TRNSYS users, I am using type 399 for coupling phase change materials with multizone type 56. And there are many unclear things about it (for me ): Is it correct to use Tstar_node as an output from type 56 and link it as an input of temperature for both surfaces Tsurface 1 and Tsurface 2 of the PCM type 399 ? I'll be grateful for any help you can provide Thank you Amin |
