modelDisableChillers
Validation sequence for disabling chillers and the associated devices
Information
This example validates
Buildings.Controls.OBC.ASHRAE.G36.Plants.Chillers.Generic.PlantEnable.DisableChillers.
It demonstrates the control of disabling plants from chiller mode (disPlaFroChi).
- Before 1800 seconds, the chiller 1 is enabled and the chiller 2 is disabled. The chilled water isolation valve is fully open, and the chiller water pump speed equals the input speed setpoint.
- After 1800 seconds, the chillers are disabled. Thus, both the chilled and condenser water isolation valves are closed, the chilled and condenser water pump speed setpoints become 0, and all the tower cells are disabled.
