AIRFLOWNETWORK:MULTIZONE:COMPONENT:ZONEEXHAUSTFAN

This object specifies the additional properties for a zone exhaust fan to perform multizone airflow calculations.

Name

Type: list of objects ( or FAN:ZONEEXHAUST)
Enter the name of a Fan:ZoneExhaust object.

Air Mass Flow Coefficient When the Zone Exhaust Fan is Off at Reference Conditions

Type: real number
Enter the air mass flow coefficient at the conditions defined in the Reference Crack Conditions object. Defined at 1 Pa pressure difference. Enter the coefficient used in the following equation: Mass Flow Rate = Air Mass Flow Coefficient * (dP)^Air Mass Flow Exponent. Used only when the fan is off.
Unit: kg/s

Air Mass Flow Exponent When the Zone Exhaust Fan is Off

Type: real number
Enter the exponent used in the following equation: Mass Flow Rate = Air Mass Flow Coefficient * (dP)^Air Mass Flow Exponent. Used only when the fan is off.
Unit: dimensionless
Minimum: 0.5
Maximum: 1.0
Default: 0.65
