.Buildings.Examples.Tutorial.CDL.System1

Information

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.

Implementation

To set control inputs, we instantiated Buildings.Controls.OBC.CDL.Reals.Sources.Constant and connected them to the pumps, the boiler and the valves.

Exercise

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.
