AIR CONDITIONING SYSTEM
GENERAL
The air conditioning system provides comfortable cabin temperatures
during hot weather operations, both on the ground or in flight. In this
system, a belt-driven compressor is located on the engine accessory
section. Three evaporator units with integral blowers are located one
each in the left and right wing root area, and one in the tailcone behind
the aft cabin bulkhead. The evaporator units direct cooled air to a series
of overhead outlets in the cabin headliner. The system condenser is
mounted in the engine compartment beneath the engine and is
provided with an inlet and outlet in the lower left side of the engine
cowling to supply cooling airflow through the condenser. Refrigerant
lines under the floorboards and in the fuselage sides interconnect the
compressor, evaporators, and the condenser.
Controls for the air conditioning system are located at the lower edge of
the instrument panel directly above the control pedestal. Controls
consist of one three-position, toggle-type air conditioning switch, and
three two-position, toggle-type fan switches, refer to Figure S7-1.
Placing the three-position switch, labeled OFF, VENTILATE, COOL,
from the OFF position to the COOL position starts the system
compressor and evaporator fans. Placing the switch in the VENTILATE
position activates only the system evaporator fans, providing uncooled
ventilating air to the cabin. The three two-position switches, all labeled
AC FANS, provide separate HIGH or LOW speed control of each
evaporator fan. System electrical protection is provided by four 15-
ampere "pull-off" type circuit breakers, labeled LEFT VENT BLWR,
RIGHT VENT BLWR, AFT VENT BLWR, and AIR COND CONT,
located on the left sidewall switch and circuit breaker panel.
