2. Pressure exchanger - Wikipedia

   en.wikipedia.org/wiki/Pressure_exchanger

   A pressure exchanger transfers pressure energy from a high pressure fluid stream to a low pressure fluid stream. Many industrial processes operate at elevated pressures and have high pressure waste streams. One way of providing a high pressure fluid to such a process is to transfer the waste pressure to a low pressure stream using a pressure ...

4. Air cycle machine - Wikipedia

   en.wikipedia.org/wiki/Air_cycle_machine

   Outside air at ambient temperature and pressure is used as the coolant in this air-to-air heat exchanger. Once the hot air has been cooled, it is then compressed by the centrifugal compressor. This compression heats the air (the maximum air temperature at this point is about 250 °C) and it is sent to the secondary heat exchanger, which again ...

5. Turboexpander - Wikipedia

   en.wikipedia.org/wiki/Turboexpander

   Schematic diagram of a turboexpander driving a compressor. A turboexpander, also referred to as a turbo-expander or an expansion turbine, is a centrifugal or axial-flow turbine, through which a high-pressure gas is expanded to produce work that is often used to drive a compressor or generator.

6. Compressed-air vehicle - Wikipedia

   en.wikipedia.org/wiki/Compressed-air_vehicle

   The tanks must be designed to safety standards appropriate for a pressure vessel, such as ISO 11439. [7]The pressure vessels or air storage tanks that can be used in compressed-air vehicles can be made of low pressure (9 atm (130 psi)) or high pressure (more than 240 atm (3,500 psi)), and can be made of composite materials like thermoplastic and fiber reinforced thermoplastics, [6] [8] that ...

7. Air compressor - Wikipedia

   en.wikipedia.org/wiki/Air_compressor

   Air compressor supplies air into a nail gun.. An air compressor is a machine that takes ambient air from the surroundings and discharges it at a higher pressure. It is an application of a gas compressor and a pneumatic device that converts mechanical power (from an electric motor, diesel or gasoline engine, etc.) into potential energy stored in compressed air, which has many uses.

8. Compressed-air car - Wikipedia

   en.wikipedia.org/wiki/Compressed-air_car

   [1] [2] Diagram of a compressed air system with a PCM heat exchanger. A compressed-air car is a compressed-air vehicle powered by pressure vessels filled with compressed air. It is propelled by the release and expansion of the air within a motor adapted to compressed air. The car might be powered solely by air, or combined (as in a hybrid ...

9. Run-around coil - Wikipedia

   en.wikipedia.org/wiki/Run-around_coil

   A run-around coil installation, serving air handling units on the roof of an office building. A run-around coil is a type of energy recovery heat exchanger most often positioned within the supply and exhaust air streams of an air handling system, or in the exhaust gases of an industrial process, to recover the heat energy. Generally, it refers ...
