Testing will soon be underway for an all electric air conditioning system for 150 seat narrowbody aircraft, that would replace the bleed air system
currently in use. This could be a big change to aircraft, as bleed air systems have been known to allow fumes to enter the cabin, causing health
effects in passengers and crew on the aircraft.
The Boeing 787 is currently the only commercial aircraft to use an electrically driven air circulation system, that includes the deicing system, and
pressurization system. The systems use a 1.4MW system, which on smaller aircraft is uneconomical due to the weight of the system. Liebherr currently
offers a 50kW generator, but a 150 seat aircraft requires more power than that. They're developing a 100kW system that will be installed on a
demonstration aircraft in the near future.
Bleed air systems are a pain, and leaks can lead to a lot of problems for passengers and crews due to some of the toxins that are in the engine. Long
term exposure to them leads to neurological problems among other health issues. I'd love to see an all electric system in use on a large scale.
