This model extends from the open loop partial model Buildings.Examples.Tutorial.CDL.BaseClasses.PartialOpenLoop, which implements the HVAC system model and a simple room. In this partial model, the room is modeled as a first order response.
To set control inputs, we instantiated Buildings.Controls.OBC.CDL.Reals.Sources.Constant and connected them to the pumps, the boiler and the valves.
Create a model, such as this model, that extends from
Buildings.Examples.Tutorial.CDL.BaseClasses.PartialOpenLoop
and adds constant input signals for the valves, pumps and the boiler.
Valves should be fully open (y=1), the boiler should be operating (y=1)
and the mass flow rates of the pumps should be set to the parameter value of
mRad_flow_nominal
and mBoi_flow_nominal
.
Simulate the model for January 15 to 16 and plot the open loop temperatures as shown below, which corresponds to a start time of 15*24*3600=1296000 seconds and a stop time of 1382400 seconds.
