Information

Overview

The HeatTransferOutside is a model for the convective heat transfer at outside walls

Concept

It allows the choice between three different models:

• after DIN 6946: h = 4+4v , where h (hCon) is the heat transfer coefficent and v is the wind speed
• after the ASHRAE Fundamentals Handbook from 1989, the way it is presented in EnergyPlus Engineering reference from 2011: h = D+Ev+Fv^2 , where h (hCon) and v are as above and the coefficients D, E, F depend on the surface of the outer wall.
  Attention: This is a combined coefficient for convective and radiative heat exchange.
• with a custom constant h (hCon) value
