Add CO2 features to large office complex air #4

GuowenLi-PhD · 2024-07-15T21:42:42Z

Main Updates:

Add CO2 property to building mix air volume and fresh air source models
Add CO2 sensors to all 15 zones and 3 AHUs and the measurements to the Read blocks following BOPTEST template
Reverse the connection of AHU return air flow sensor to make the measurement value positive
Add example models to subsystem models for testing purposes

Remain Question

In MultizoneOfficeComplexAir.TestCases.TestCase, the code of MultizoneOfficeComplexAir.BaseClasses.LoadSide.LoadWrapper needs to be placed after MultizoneOfficeComplexAir.BaseClasses.HVACSide.HVAC to simulate successfully, otherwise the model initialization fails. The specific reason for this setting needs to be clarified.
Potential solution: please refer to pull request Adjusted system equipment sizing and Resolved nonlinear system warnings. #7 : To avoid initialization failure, set initial economizer damper positions as open (refer to the commit e370209)

Issue406 spawn support

1. Replace Medium Air with Buildings library air media package with CO2 2. CO2 inputs are calculated based on the number of occupant in each thermal zone 3. Add CO2 sensors for each thermal zone

However, error: could not solve simplified initialization for homotopy method; Integrator failed to start model.

Although 'TestSuccess' run successfully, we need to debug why 'TestCase' failed to initialize since two system models are almost the same.

…eOffice_complexAir

LoadWrapper needs to be put behind of HVAC to avoid model initialization failure (but reason is not clear yet)

The testcase model after adding CO2 sensors cannot be solved by Dymola 2021 but Dymola 2024. The following errors are reported:

ERROR: Failed to solve nonlinear system using Newton solver.
  During initialization at time: 15552000

  Common causes:
   * The system of equations has no solution - the residual will be above zero.
     - This may be caused by initial conditions not being fully specified, check the translation log.
     - In some cases the event-logic can cause this.
   * Starting values are too far from the solution, see homotopy in the manual.
     - In rare cases this could occur at events.
   * The equations are too discontinuous for the nonlinear solver - the residual will have knees.

The initialization CO2 values of the AHU-level airflows starts off at 0 while the CO2 values for the zone air flows seem to start at 400 ppm. @GuowenLi-PhD , please help check and address this issue. Not sure if it relates to the initialization error in Dymola 2020.

Also, please also help look into the highlighted circle area -> why does the outdoor air CO2 have such behavior?

Reply to @terrancelu92

The initial sensor value starts from 0 because the default C_start = 0 in the CO2 sensor. As the shown in the following screenshot, the solution is to change C_start from 0 to 400 ppm which is the same as the outdoor air CO2 ppm.
The up-down behavior of the outdoor air CO2 sensor occurred when (1) the supply air instantaneously reversed as shown in the following highlighted plots and (2) the default setting of allowFlowReversal in CO2 sensor is true. The solution is to change allowFlowReversal of CO2 sensor to be false.
