Vapor Cycle System

Air conditioning systems create a safe and comfortable environment for passengers and crews in the aircraft cabin.

In some cases like on helicopters or business aircraft, the cabin air conditioning is based on a vapor cycle system.

Liebherr has developed its own range of compressors up to 30 kW of various technologies: scroll, screw, centrifugal. This allows to fully custom design vapour cycle systems, thus offering the best suited system for the aircraft.

Liebherr designs, develops, manufactures, assembles and tests such systems and masters all components required. All kind of aircraft that need such function are supplied with Liebherr vapor cycle systems, like commercial airplanes, helicopters, small business jets or fighters (pod cooling).

Various components like heat exchangers, evaporators, condensers, water extractors, sensors and controllers are part of the system as well.

A compressor that can be mechanically or electrically driven is the heart of such systems..Liebherr has developed its own range of scroll, screw and centrifugal compressors with outputs up to 30 kW. This allows to fully custom design vapour cycle systems for every aircraft.
