Buildings.Applications.DataCenters.DXCooled.Controls.Validation
Collection of validation models
Information
This package contains validation models for the classes in Buildings.Applications.DataCenters.DXCooled.Controls.
Note that most validation models contain simple input data which may not be realistic, but for which the correct output can be obtained through an analytic solution. The examples plot various outputs, which have been verified against these solutions. These model outputs are stored as reference data and used for continuous validation whenever models in the library change.

Buildings.Applications.DataCenters.DXCooled.Controls.Validation.AirsideEconomizer
Example that demonstrate the use of model
Buildings.Applications.DataCenters.DXCooled.Controls.AirsideEconomizer
Information
This example demonstrates how the outside air damper position changes under different cooling mode. During the first 120s, the system is in free cooling mode, and the damper position is controlled to maintain the mixed air temperature at its setpoint. In the second 120s, the system is in partial mechanical cooling mode and the outside air damper is fully open. As a result, the mixed air temperature is equal to the outdoor air temperature. In the last 120 seconds, the system is in fully mechnical cooling mode, which means the outside air damper is fully closed, and the mixed air temperature equals to the return air temperature.

Buildings.Applications.DataCenters.DXCooled.Controls.Validation.Compressor
Example that demonstrates the use of a speed controller for DX coil
Information
This example demonstrates how the speed signal of a variable-speed DX unit can be controlled. The detailed control logic can be refered in Buildings.Applications.DataCenters.DXCooled.Controls.Compressor.

Buildings.Applications.DataCenters.DXCooled.Controls.Validation.CoolingMode
Example that demonstrates the use of cooling mode selection for the airside economizer
Information
This example demonstrates how the cooling mode signal can be generated according to varying outside air dry bulb temperature, outside air dewpoint temperature, return air temperature and supply air temperature setpoint.The detailed control logic can be refered in Buildings.Applications.DataCenters.DXCooled.Controls.CoolingMode.
