#### 7.1.2.9 IfcEvaporatorTypeEnum

Enumeration defining the typical types of evaporators.

Enumerated Item Definitions:

- DIRECTEXPANSION: Direct-expansion evaporator.
- DIRECTEXPANSIONSHELLANDTUBE: Direct-expansion evaporator where a refrigerant evaporates inside a series of baffles that channel the fluid throughout the shell side.
- DIRECTEXPANSIONTUBEINTUBE: Direct-expansion evaporator where a refrigerant evaporates inside one or more pairs of coaxial tubes.
- DIRECTEXPANSIONBRAZEDPLATE: Direct-expansion evaporator where a refrigerant evaporates inside plates brazed or welded together to make up an assembly of separate channels.
- FLOODEDSHELLANDTUBE: Evaporator in which refrigerant evaporates outside tubes.
