modelHeatGain

Model to convert internal heat gain signals

Extends from Buildings.BaseClasses.BaseIcon (Base icon).

Information

This model computes the radiant, convective sensible and latent heat flow rate. Input into this model are these three components in units of [W/m2]. The inputs need to be positive quantities if heat or moisture is added to the room. The outputs are

  • the radiant heat flow in Watts,
  • the convective heat flow in Watts, and
  • the water vapor released into the air.
