[EnergyPlus_Support] the question of Tube and Fin Thermal Conductivity



Dear all,

      In the mode of Coil:Cooling:Water:DetailedGeometry,I find the default of Tube Thermal Conductivity and Fin Thermal Conductivity is 0.386 w/(m.k) and 0.204 w/(m.k),respectively.

      But the thermal conductivity of metallic material is rather large, such as the thermal conductivity of copper(Cu),which is the common of Cooling Coil,is 398w/(m.k).

       How to explain it ? 


            Best Regards!
