Environmental System
• Note •
To facilita te fa ster c abin cooli ng, prior to engine start leave the
cabin doors open for a short time to allow hot air to escape.
Standard cabin heating and ventilation is accomplished by supplying
conditioned air from the heat exchanger for heating and windshield
defrost and fresh outside air for ventilation. The environmental system
consists of a fresh air inlet in the RH cowl, a heat exchanger around
the exhaust system crossover tube, an air mixing chamber, air ducting
for distribution, a distribution manifold, a windshield diffuser, crew and
passenger air vents, and associated plumbing, controls, actuators,
wiring for system flow-selection and temperature control
An optional 3-speed blower fan is available to supplement airflow when
ram air may be inadequate such as during ground operation.
28 VDC for Environmental System Control Panel operation is supplied
through the 2-amp CABIN AIR CONTROL breaker on MAIN BUS 1.
The optional Blower Fan is powered by 28 VDC supplied through a 15-
amp CABIN FAN breaker on A/C BUS 2.
Serials with Optional Air Condition System:
The optionally installed Air Conditioning System is designed to cool
the cabin to desired temperature settings and maintain comfortable
humidity levels. The system consists of an engine driven compressor,
condenser assembly, evaporator assembly, exhaust heat exchanger,
fresh air inlet, air-mixing chamber, blower fan, distribution manifold,
ducting, windshield diffuser, vent outlets, associated plumbing,
controls, actuators, wiring for system flow-selection and temperature
control.
28 VDC for Air Conditioner Condenser operation is supplied through
the 15-amp A/C COND breaker on A/C BUS 1.
28 VDC for Air Conditioner Compressor operation is supplied through
the 5-amp A/C COMPR breaker on A/C BUS 2.
The airplane engine must be running for the air conditioner to operate.
Distribution
Ventilation and cooling is provided by ducting fresh air from a NACA
inlet on the RH cowl to the mixing chamber located on the lower RH
portion of the firewall. Depending on operating mode and temperature
