Air Cycle System
This is the air source for conditioned and pressurization air for turbine aircraft with air cycle systems.
What is compressor bleed air?
This component in a vapor cycle system is responsible for holding freon that is not currently actively being used for cooling.
What is the receiver-dryer?
This is the state of refrigerant leaving an expansion valve in a vapor cycle system.
What is low pressure liquid?
This type of refrigerant is more toxic to the environment and it is illegal to vent into the atmosphere.
What is R12?
This is a potential hazard of exhaust shroud type cabin heaters, and a reason exhaust components under the shroud should be carefully inspected.
What is carbon monoxide poisoning?
This component does an initial cooling of bleed air before entering the air cycle machine.
What is primary heat exchanger?
This component in a vapor cycle system cools the air in the cabin.
What is the evaporator?
This component in a vapor cycle system has high pressure liquid going in and out.
What is the receiver-dryer?
This type of refrigerant is more modern and generally considered less environmentally hazardous.
What is R134?
This is the air source in a combustion heater that takes heated air and carries it to the cabin.
What is ventilating air?
This component in an air-cycle system is responsible for the final temperature adjustments before it goes to the cabin.
What is bleed-air bypass OR trim air valve OR mixing valve?
This component keeps the refrigerant moving through the system.
What is the compressor?
This is the state of the refrigerant leaving the compressor of a vapor cycle system.
What is high pressure vapor?
When purging freon from a vapor-cycle system, the level of this leaving the system should be monitored so the same amount goes back in.
What is refrigerant oil?
This is the section of a combustion heater system that provides the heat that is later carried to the cabin.
What is the combustion chamber?
This component in an air-cycle machine is responsible for the final cooling of the conditioned air.
What is the expansion turbine?
This component controls the amount of freon let into the system for cooling.
What is the expansion valve?
This component of a vapor cycle system has a low-pressure liquid going in, and a low-pressure vapor coming out?
What is the evaporator?
When passed over an open flame R12 refrigerant turns into this type of gas that is probably a war crime or something.
What is phosgene gas?
Most combustion heaters have one of these against them, legally requiring pressure decay checks, leak checks, and visual inspections, among others.
What is AD (Airworthiness Directive)?
This is the term for the component assembly in an air cycle system that compresses then does final cooling of the air.
What is the air-cycle machine?
This component of a vapor cycle system sends the heat from the air out of the cabin into the ambient air.
What is the condensor?
This component in a vapor cycle system has high pressure vapor going in, and high pressure liquid coming out.
What is the condensor?
Final servicing of freon in a vapor cycle system should be done in this state through this "side" of the system.
What is low-pressure vapor?
This component in a combustion heat system is engaged or disengaged if a safety switch trips, or if temperature sensors detect that more heating is required.
What is the fuel control solenoid?
