through the three speed blower. The three-speed blower is responsible for pushing
both air conditioned air and conditioned bleed air through the airflow ducting to the
various vents. The primary flow of conditioned bleed air is to the floor and window
defog vents, while air conditioned air generally flows through the instrument panel
and mid waist vents.
There are two additional diverter valves within the forward evaporator that are
responsible for mixing air conditioning air with conditioned bleed air and further
routing this air for defogging and dehumidification.

AFT EVAPORATOR
The aft evaporator, located under the baggage compartment floor, supplies
conditioned bleed air and air conditioned cooled air to the cabin foot warmer outlets
and overhead gaspers using a 3-speed, 28 volt DC fan.
Conditioned bleed air is normally routed to the aft evaporator from the left engine
through the Cabin Shutoff Valve. Once within the aft evaporator, the conditioned
bleed air passes through a bypass valve that diverts the air under floor as necessary
to meet cabin zone temperature demand. Conditioned bleed air that was not
diverted underfloor is then routed directly to the floor vents in the cabin temperature
zone.
