Abstract (en)
[origin: EP3339128A1] An air-conditioning unit (1) on a train car (4) for cooling a tunnel where trains run comprising: an inlet (10) for sucking air (HOT AIR) from exterior of the train car (4); a refrigerant circuit (7) having a first heat exchanger (12, 12s) operating as an evaporator when the train car (4) runs in a tunnel (3), a second heat exchanger (16, 16s) operating as a condenser when the train car (4) runs in a tunnel (3), an expansion device (29, 29s) which permits the expansion of the condensed fluid by the second heat exchanger (16, 16s), and a compressor (25, 25s); an outlet (13) for cooled air supplied to the exterior of the train car (4) in the tunnel (3); a fan (50) coupled with the first heat exchanger (12, 12s) and blowing the sucked air passed through the first heat exchanger (12, 12s) from the inlet (10) towards the outlet (13); and a heat collector (20) that receives air passing through the second heat exchanger (16, 16s) and stores the received thermal energy.
