Radiationwith a supporting ConstraintBlock
As we saw earlier, the fan power ratio is either 1.0 (on) or off (0.0), as determined via the input Port
iWaterFanPower. Note that even when the fan is completely off there is some radiation (and it turns out the intrinsic
radiationFactor for this is equal in strength 0.1 to the
Through dimensional analysis it was determined that:
This implies the explicit ValueTypes
FanEfficiency have units J/(K⋅s).
It seems the radiation rate is proportional to the difference between the water temperature (as received via the
iWaterTemperature Port from the
Heating computation block) and the
roomTemperaturehere and the
VaporPressureCalculationwould seem to be the same (30 °C), so SHOULD be shared via some common system-wide block!
Although the full physical setup of the system is not described in the spec example, it seems that the radiating water is somehow interacting with the room environment. (Later we'll see that the
WaterTank seems to be exposed also to a lower environmental temperature of 20 °C.)
