Validation model for fan speed subsequence

Buildings.Controls.OBC.ASHRAE.G36.FanCoilUnits.Subsequences.Validation.FanSpeed

Information

This example validates Buildings.Controls.OBC.ASHRAE.G36.FanCoilUnits.Subsequences.FanSpeed. Each of the six instances of the controller represents operation with different inputs for heating and cooling loop signals, as well as the operating mode and fan proven on signal, and different configuration parameters of fan coil unit with presence or absence of heating and cooling coils, as described by the comment for each instance.

Buildings.Controls.OBC.ASHRAE.G36.FanCoilUnits.Subsequences.Validation.PlantRequests Buildings.Controls.OBC.ASHRAE.G36.FanCoilUnits.Subsequences.Validation.PlantRequests

Validation model for subsequence for calculating the plant requests

Buildings.Controls.OBC.ASHRAE.G36.FanCoilUnits.Subsequences.Validation.PlantRequests

Information

This example validates Buildings.Controls.OBC.ASHRAE.G36.FanCoilUnits.Subsequences.PlantRequests for fan coil units. The three instances of the controller are as follows:

Each instance is subjected to an increasing deviation of the measured supply temperature TAirSup from the supply temperature setpoint TSupSet that results in an increasing number of requests from the controllers.
