METHOD FOR COOLING TUBE RAILWAY CARS WITHOUT RELEASING HEAT IN THE UNDERGROUND AND CAPABLE OF COOLING EVEN THE STATIONS

摘要

The invention concerns a method for cooling tube railway cars without releasing heat in the underground and capable of cooling even the stations. The method comprises a step which consists in storing cold in soft ice, in particular derived from a combined mixture of water and glycol. It is thus possible to pump soft ice for its transfer from a storage volume to a use volume.
