IfcHeatExchangerType

Definition from IAI: The element type IfcHeatExchangerType defines a list of commonly shared property set definitions of a heat exchanger and an optional set of product representations. It is used to define a heat exchanger 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 heat exchanger type is used to define the common properties of a heat exchanger that may be applied to many occurrences of that type. A heat exchanger is a device used to provide heat transfer between non-mixing media such as plate and shell and tube heat exchangers.

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