Abstract Research purposes: The cold insulation of metro system in winter should be focused. The vehicle regenerative braking energy is a measure of energy saving operation of the subway system. In this paper， the vehicle regenerative braking energy recovery is analyzed from the point of view^ of the environment control system. The metro environment control system in cold region using vehicle regenerative braking energy are analyzed and discussed. Research conclusions:( 1 ) Train regenerative braking energy recovery mode is recommended ： regenerative electric energy is a part of the traction network，the other is absorbed by vehicle in the traction condition， the remaining renewable power can be set up through the vehicle auxiliary inverter into alternating current，the vehicles auxiliary power equipment used or car mounted device in the form of heat emitted into the subway tunnel. (2 ) This regenerative braking energy recovery mode on the one hand can realize that the electric energy is absorbed by the counterparts，reducing traction braking energy consumption. ( 3 ) On the other hand，the electric energy can be excluded from the subway train car，which can be emited into the subway tunnel，in summer the transition season can be ruled out by the column car， no additional energy consumption. ( 4) The research conclusion can provide a reference for the vehicle regenerative braking energy recovery in the cold area.
