modelPlantRequests
Validation model for subsequence for calculating the plant requests
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:
-
plaReqrepresents a controller instance for a system with both heating and cooling coils. -
plaReq1represents a controller instance for a system with just a cooling coil. -
plaReq2represents a controller instance for a system with just a heating coil.
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.
