In addition, it is not suitable for the regular opening of doors “, explains the RATP.

On board public transport in Île-de-France, 3 different systems are installed.

• Refrigerated mechanical ventilation, which comes closest to air conditioning that we know. It consists of using outside air and produces a temperature difference with the outside of a few degrees to bring travelers a feeling of freshness “.
• Forced mechanical ventilation. This system ” draws in air from the outside through vents located on the roof of the equipment, thus diffusing air by natural convection for passengers “.
• And, standard / light air conditioningconsisting of ” cooling of a mixture of indoor air and outdoor air / recycling of indoor air in a closed circuit “, but very little used (just in a few buses), because very consuming.

The other materials are simply provided with natural ventilation: the ventilation only comes “ existing air currents between the inside and the outside of the equipment, created in particular thanks to skylights on the roof “. These trains are, unsurprisingly, those in which it is likely to be the hottest in the middle of summer.
