This model computes the distribution of the infrared radiant heat gain
to the room surfaces.
The infrared radiant heat gain Q is an input to this model.
It is distributed to the individual surfaces according to
Qi = Q Ai εi ⁄
∑k Ak εk.
For opaque surfaces, the heat flow rate
Qi
is set to be equal to the heat flow rate at the heat port.
For the glass of the windows, the heat flow rate
Qi is set to the radiosity
Ji
that will strike the glass or the window shade.

Reformulated to reduce use of the division macro
in Dymola.
This is for issue 417.

July 16, 2013, by Michael Wetter:
Added assignment of heat port temperature instead of heat flow rate
for the cases where a construction has been conditionally removed.
This is required to avoid a singularity.

Changed model because the outflowing radiosity has been changed to be a non-negative quantity.
See track issue #158.
