Autorail à Grande Capacité (AGC)

HVAC units developed and manufactured by Liebherr are integrated in SNCF’s Autorail à Grand Capacité (AGC) trains by Alstom, which are operated in the Occitania Region (France). The air-conditioning system based on environmentally friendly air cycle technology uses only ambient air as a coolant instead of conventional chemical refrigerants.

Heating-, ventilation- and air-conditioning system based on aircycle technology

Technology

Cooling without refrigerants is the concept behind Liebherr's air cycle heating-, ventilation- and air-conditioning (HVAC) systems.It operates with an open loop process and draws the air required for the cooling process from the environment. The air expands and thus cools. Then the cool air runs through the heat exchanger and is subsequently returned to the ambience. The HVAC system complies with all common passenger comfort requirements such as UIC 553, EN13129 and EN14750, and – as a real alternative to chemical refrigerants – helps to reduce the greenhouse effect according to worldwide HFC regulations.
