IfcCoolingTowerType

Definition from IAI: The element type IfcCoolingTowerType defines a list of commonly shared property set definitions of a cooling tower and an optional set of product representations. It is used to define a cooling tower specification (i.e. the specific product information, that is common to all occurrences of that product type).

> NOTE: The product representations are defined as representation maps (at the level of the supertype IfcTypeProduct, which get assigned by an element occurrence instance through the IfcShapeRepresentation.Item[1] being an IfcMappedItem.

A cooling tower type is used to define the common properties of a cooling tower that may be applied to many occurrences of that type. A cooling tower is a device which rejects heat to ambient air by circulating a fluid such as water through it to reduce its temperature by partial evaporation. Cooling tower types may be exchanged without being already assigned to occurrences.

The occurrences of the IfcCoolingTowerType are represented by instances of IfcEnergyConversionDevice or its subtypes.
