Buildings.Fluid.Chillers.ModularReversible.RefrigerantCycle.BaseClasses.NoCooling
Placeholder to disable cooling
Information
Using this model, the chiller will always be off. This option is mainly used to avoid warnings about partial model which must be replaced.
Extends from PartialChillerCycle (Partial model of refrigerant cycle used for chiller applications).
