Fresh Air Required Amount of fresh air required in cfm.
FreshAirRatio is equal to FreshAirReq
divided by SrcBoxFlow. When
FreshAirRatio is large (greater than
100 percent), there is insufficient fresh
air being supplied to the zone even if
the supply air is 100 percent fresh air.
When FreshAirRatio is small, there is
sufficient fresh air being supplied to
the zone. FreshAirRatio is used for
coordination within the HVAC
subsystem and energy management
decisions by the supply equipment.
