The invention discloses a direct-current power supply rail train braking energy conversion and utilization method. The method comprises the following steps that electric energy fed back by electric braking when a train enters a station is sent to a direct-current power grid, so as to rise the voltage of the direct-current power grid; one part of electric energy enabling the voltage of the direct-current power grid to rise is used for electric energy consumption of other train traction systems in the section, and the other part is collected; the collected electric energy is converted into heat energy, and the heat energy is correspondingly stored; and the stored heat energy is converted into the refrigerant input energy of the station air conditioner and sent to a station air conditioner system.The regenerative braking energy of the direct-current power supply rail transit train is converted into the refrigerant input energy of the station air conditioner and the energy of the train traction systems, the station air conditioning system and the train traction systems cooperatively recycle and reuse electric energy, energy conservation and emission reduction are achieved, the train regenerative braking utilization rate is improved, and the input of vehicle-mounted braking resistors is reduced; and in addition, a station air conditioner takes a lithium bromide aqueous solution or ammonia water as a working medium, and atmospheric ozone layer is not damaged, so energy conservation and environment protection are achieved.
