In heat accumulation of the supercooling heat accumulating material, the channel of the upstream heat accumulator and the channel of the downstream heat accumulator are set in a serial connection state by a serial connection pipe. In a temperature rise mode, fluid that has passed through the channel of the upstream heat accumulator flows in a bypass pipe.

A vehicle provided with a power plant having at least one heat engine, the vehicle having an air-conditioning system comprising a fluid circulating in a fluid circulation system, the fluid circulation system comprising at least one pump configured to cause the fluid to circulate in a fluid circuit. The vehicle comprises one injection member per heat engine configured to inject the fluid into the associated heat engine, the vehicle comprising a back-up circuit fluidly connecting the fluid circulation system to each injection member, the back-up circuit comprising a distribution device controlled by a controller to authorize, on command, circulation of the fluid towards an injection member.

A phase-change energy storage air duct of an automobile air conditioning system. A phase-change energy storage unit (2) is configured inside an air duct (1) of an air conditioning system. By means of phase-change heat absorption or release, residual heat in the air is absorbed, and the heat is released to air with a lower temperature, so that energy is recycled to achieve energy saving. The temperature of air entering a room or a carriage is kept stable, and thus the user experience is improved. When the air conditioning system fails, the phase-change energy storage unit (2) can still utilize stored cooling capacity or heat to cool down or heat up air in the air duct, so that a supply of air can be kept stable for a period of time, and thus the user experience is improved. The present application also relates to an automobile air conditioning system.
