7-21 CABIN HEAT, VENTILATION, DEFROST, AND AIR-
CONDITIONING
The environmental control system (ECS) for the aircraft consists of forward
cabin bleed air heat/defrost, aft cabin electric heat, and a forced air ventilation
system. All environmental control systems are activated and controlled
through a touch screen display located on the instrument panel below the
right audio panel. The control head receives input information from the pilot
and the electronic control unit displays the information. Fault codes will
also be displayed on the LCD screen for troubleshooting purposes. Refer to
“Chapter 21” of the KODIAK 100 Maintenance Manual for further information
on the ECS and maintaining its components.
TEMPERATURE CONTROL
The electronic control unit (ECU) receives input data from the environmental
control systems and controls the environmental systems accordingly.
All environmental controls systems are activated and controlled through a
touch screen display located on the instrument panel below the right audio
panel. This touch screen controller/display receives signals from the two
thermostats in the cabin. The user sets the desired temperature using the
temperature selector and the controller will activate either the blower or heat
as appropriate to maintain the set temperature within 5 degrees. If no air
conditioning is installed, the system will continue to activate the blowers, but
may not be able to maintain the set temperature.
The outside air temperature (OAT) sensor for the environmental control
system (ECS) is located in the fresh air inlet on the right side of the cowling
and is exposed to ambient airow. The sensor continually measures
the temperature of the air entering the cabin, setting a basic variable for
temperature regulation within the aircraft.
AUTOMATIC CLIMATE CONTROL SYSTEM
The Automatic Climate Control System (ACCS) used in the KODIAK 100 is
a fully automatic system with manual operation capabilities. The pilot may
choose between manual or automatic operation, and the system offers 11
choices for heater and air conditioning blower speed. Air distribution and
temperature regulation is accomplished with a combination air distribution
actuator position, blower speed setting and the use of either fresh, engine
bleed, recirculated air, or cold air. Additionally, the heater temperature door
actuator utilizes a feedback potentiometer. These actuators move the air
distribution doors to the proper position according to information sent by the
ECU.
