The air cycle machine (ACM) is driven by turbine engine bleed air that first passes through a primary heat exhanger (much like an intercooler for a turbocharged automotive engine) that significantly lowers the temperature of the 300-500 degree bleed air. After leaving the primary heat exchanger the air flows into a compression turbine that increases the pressure of the air and also increases the temperature.
After leaving the compression turbine, the air flows into a secondary heat exchanger that once again lowers the temperature of the air. At this point, the air is at extremely high pressure and relatively low temperature. From the secondary heat exchanger the air flows into the "expansion turbine" where this high pressure air is used to drive a turbine wheel that performs several functions: 1. It extracts energy from the high pressure air, 2. Allows the pressurized air to expand, 3. Drives the compression turbine. The extraction of energy from the air and subsequent expansion of the gases drastically lower the temperatures of the air. In fact, the air temperature is lowered so much that often times hot bleed air is bypassed around the ACM and ducted to the air coming out of the expansion turbine to raise the temperature above freezing.
The output air that is coming out of the ACM is then sent through a moisture removal system that essentially uses a fine mesh weave to collect small droplets of water. This removal of moisture helps to control the humidity of the air entering the cabin and it also prevents icing downstream in the system.

How does hydraulic machine work?
Hydraulic machinery uses a liquid usually oil under pressure to transmit energy, hydraulic machine use the power of fluid to work, hydraulic machine are part of our everyday life.
What is work of avionic aircraft maintenance engineer?
Responsible for the work on the Avionics of an Aircraft composed of the following: communications, navigation and guidance, display systems, flight management systems, sensors and indicators, weather radars, electrical systems and various other computers onboard modern aircraft and spacecraft. It also includes the hundreds of systems that are fitted to aircraft to meet individual roles; these can be as simple as a search light for a police helicopter or as complicated as the tactical system for an airborne early warning platform.
What is mechalical advantage?
is the advantage point in witch work input and work output are used within a machine
How inefficiencies of compressor and turbine affect back work ratio and efficiency of gas turbine?
Inefficiencies in the compressor of a gas turbine cycle increase the back-work ratio and decrease the thermal efficiency of the gas turbine cycle, since they increase the compressor work.
What is a machine file tool used for?
because it makes work easier
Is a washing machine programme dial an input or an output?
It is both. It is where you set your machines cycle and where you can see what work is being done throughout the cycle.
how can i wash my washing machine easily?
You can get a type of cleaner that you simply throw into your wash cycle and let the washer do the work. All you would have to do is put the cleaner in the washing machine without soap and turn on the cycle.
What is bootstrap sweep circuit?
A bootstrap sweep circuit is a connection between two machines that can be used by themselves. It would be like linking a computer to a printer without Internet capabilities. The printer can work without the Internet on its own and so can the computer.
Who does a led work?
LED is working with the use of washing machine. It just circulates the flow of water from east to west and vice versa. After the circulation you can now drain the washing machine for a new cycle.
Work performed on a machine?
The work done by a machine is called work output
Who works on an aircraft?
Many specialist technicians work on modern aircraft.
What is work done on a machine called?
Machine work
What determines the overhaul cycle of military aircraft?
The overhaul cycle of military aircraft is item specific. Each and every aircraft goes through a though check list after each flight has ended. This procedure is known as a post flight inspection.Any abnomalities would be noted at this time and the appropriate work orders would then be generated.Also each aircraft goes through more detailed inspections of engines and flight electronics every 50, 100, flight hours. Also aircraft may be inspected at any time due to a request by commanding pilot whenever he/she may feel the procedure may be required. I.E. aircraft controls suspisous handling qualities. ect,
How do you clean a smelly washing machine?
To clean a smelly washing machine, you can run a cycle with hot water and vinegar or baking soda to remove mildew and odor-causing residues. Wipe down the door seal, detergent dispenser, and drum with a vinegar solution as well. Finally, leave the door open after each use to allow the machine to dry completely and prevent mold growth.
The work that the simple machine does is called the work?
The work that a simple machine does is called mechanical work. It refers to the amount of force applied over a distance to accomplish a task using the simple machine.
How much minimum engine can work for an aircraft?
It depends on the size of the aircraft and the power of the engine
How do air brakes work on commercial aircraft?
Airbrakes on commercial aircraft are hydraulically operated.
