Example of a building that uses an EMS actuator.
The building has three thermal zones that are simulated in EnergyPlus.
In the EnergyPlus model, the west-facing thermal zone has
a window blind that is open if its control signal is 0 or closed if it is 6.
The control sequence obtains
the room air temperature of the west-facing zone
from the Modelica instance zonWes
,
and connects it to a hysteresis block that switches its output to
true
if the zone temperature is above 24°C,
and to false
if it drops below 23°C.
The instance incBeaSou
obtains from EnergyPlus the
incident solar beam radiation on the outside of the window, and feeds it
into a hysteresis block that outputs true
if its input exceeds
200 W/m2, and switches to false
if it drops
below 10 W/m2.
The instance actSha
connects to the EMS actuator in EnergyPlus
that activates this shade.
If both outputs of the hysteresis blocks
are true
, then the EnergyPlus shade actuator is deployed by
setting the input of actSha
to 6
.
Otherwise, the input is set to 0
.
To the right of the model, there are three idealized cooling systems that keep the room air temperature below 25°C in each of the three zones. Also, each zone is connected to a constant, unconditioned outside air supply.
The internal heat gains are set to zero in Modelica because these are specified in the EnergyPlus model.
