An air cycle machine (ACM) is the refrigeration unit of the environmental control system (ECS) used in pressurized gas turbine-powered aircraft. Normally an aircraft has two or three of these ACM. Each ACM and its components are often referred as an air conditioning pack.
The primary component for the functioning of the cold air unit (CAU) is the Air Cycle Machine (ACM) cooling device. Some aircraft, including early Boeing 707 aircraft, used vapor-compression refrigeration like that used in home air conditioners. An ACM uses no Freon: the air itself is the refrigerant. The ACM is preferred over vapor cycle ...
An airliner fuselage, such as this Boeing 737, forms an almost cylindrical pressure vessel.. Cabin pressurization is a process in which conditioned air is pumped into the cabin of an aircraft or spacecraft in order to create a safe and comfortable environment for humans flying at high altitudes.
The company's first major product was an oil cooler for military aircraft. Garrett designed and produced oil coolers for the Douglas DB-7. [9] Boeing's B-17 bombers, credited with substantially tipping the air war in America's and Great Britain's favor over Europe and the Pacific, were outfitted with Garrett intercoolers, as was the B-25.

It is then fed to an air cycle machine unit that regulates the temperature and flow of air into the cabin, keeping the environment comfortable. [6] This process is contrary to the common misconception that cabin air in airplanes is the same air being recycled. [7] Bleed air is also used to heat the engine intakes. This prevents ice from forming ...
Used in conjunction with a heat exchanger, the units reduced the temperature of compressor-bleed air by more than 300 °C. The use of epoxy resin/glass fibre-reinforced plastics for airscrew spinners, blade root fairings and other components were also developed extensively by de Havilland Propellers Ltd. at their Stevenage plant.
