IfcAirTerminalBoxTypeEnum

IfcAirTerminalBoxTypeEnum

Definition from IAI: This enumeration identifies different types of air terminal boxes.

Valid enumerations are:

CONSTANTFLOW: Terminal box does not include a means to reset the volume automatically to an outside signal such as thermostat.
VARIABLEFLOWPRESSUREDEPENDANT: terminal box includes a means to reset the volume automatically to a different control point in response to an outside signal such as thermostat: air-flow rate depends on supply pressure.
VARIABLEFLOWPRESSUREINDEPENDANT: terminal box includes a means to reset the volume automatically to a different control point in response to an outside signal such as thermostat: air-flow rate is independant of supply pressure.
USERDEFINED: User-defined terminal box.
NOTDEFINED: Undefined terminal box.

HISTORY: New enumeration in IFC R2.0

EXPRESS specification:

TYPE IfcAirTerminalBoxTypeEnum = ENUMERATION OF

(	CONSTANTFLOW, VARIABLEFLOWPRESSUREDEPENDANT, VARIABLEFLOWPRESSUREINDEPENDANT, USERDEFINED, NOTDEFINED);
