Air Conditioning Flashcards
What controls the associated ECS pack discharge air temperature and prevents ice accumulation inside pack by monitoring compressor inlet and compressor outlet temperature?
Air Conditioning Controllers (ACC’s)
How many temperature zones are there on the G650?
Three: COCKPIT, FWD CABIN, and AFT CABIN
What happens when a PACK switch is selected to ON?
Pack valve is opened and control circuitry is initiated in ACC
What pack outlet temperature would you expect with packs operating normally?
35°F
What do temperature control rheostats control?
They control trim air valves that control the mixing of hot air from a hot air manifold with cold air from a cold air manifold to produce comfortable air.
How can you select ram air?
Select RAM AIR to RAM or turn both PACK switches to OFF
When does the ram air check valve open?
Pressure in the ducts and pressure vessel must be equal to or less than pressure outside
What’s the purpose of ozone filters?
They change bleed air ozone to oxygen before it enters packs to enhance pax comfort
With AUTO TEMP SELECT switches selected to ON, what temperatures are displayed inside the temp windows and how are they displayed on the ECS/PRESS synoptic page?
The temp windows reflect selected temperatures for respective zones which are also displayed in blue digits on the ECS/PRESS synoptic page
What’s the temperature select range in the automatic mode?
60 to 90°F
How is temperature controlled in the manual mode?
When in amber MAN position, COLD-HOT control knobs allow crew to manually control temp for their respective zones between full cold of 35°F and full hot maximum of 230°F
What type of air comes from the overhead gaspers and baseboards?
Cold air always comes from the overhead gaspers in both cockpit and cabin while conditioned air comes from the baseboards or foot level outlets
