A cooled beam (or chilled beam) is a device typically used to cool air by circulating a fluid such as chilled water through exposed finned tubes above a space. Typically mounted overhead near or within a ceiling, the cooled beam uses convection to cool the space below it by acting as a heat sink for the naturally rising warm air of the space. Once cooled, the air naturally drops back to the floor where the cycle begins again.

|CorrectPredefinedType|| : ||
Either the PredefinedType attribute is unset (e.g. because an IfcCooledBeamType is associated), or the inherited attribute ObjectType shall be provided, if the PredefinedType is set to USERDEFINED.
|CorrectTypeAssigned|| : ||
Either there is no cooled beam type object associated, i.e. the IsTypedBy inverse relationship is not provided, or the associated type object has to be of type IfcCooledBeamType.
