ENVIRONMENTAL CONTROL SYSTEM
[HEATED & REFRIGERATED AIR]
NO. 222-706-018-XXX
The Environmental Control System (ECS) provides a comfortable environment for the
pilot and passengers when operating the helicopter under severe climatic conditions.
The installation is a completely integrated heating and cooling system which when in
use, automatically maintains a precisely controlled cabin temperature, and also improves
the comfort level by removing moisture from the circulating air. The ECS kit is designed
to interface with the existing crew and cabin ventilation air distribution / windshield
defogging system, and with provisions in the airframe and passenger doors for air ducts
and outlets. The engine bleed-air powered heating / cooling unit is located beneath
a removable panel in the baggage compartment floor. System operation is controlled
by overhead console switches.
Two separate air distribution systems provide conditioned de-humidified air to the cabin.
The COOL air system is located in the cabin roof, and feeds into the standard air distribution
outlets in the cabin and crew compartment. The WARM air system is located beneath
the cabin floor, and inside the doors. The WARM air system also defogs the windshield
and the lower nose windows. Ten adjustable outlets provide warm air to the cabin; four
in each aft cabin door and one on each side of the center console. Direction of conditioned
air to the respective distribution systems is accomplished by remotely operated diverter
valves. Heated dry air is directed to the windshield defog system when HEAT is selected
and the pilot actuates the DEFOG lever, located on the right side of the console.
