ENERGY-ACTIVE URBAN AREA METRO WITH ZERO CONSUMPTION OF THERMAL ENERGY FROM EXTERNAL SOURCES Russian patent published in 2018 - IPC E21F1/08 

FIELD: heat engineering; urban economy.

SUBSTANCE: invention relates to the field of urban transport, namely, to the heat supply of metro facilities. In the method, the energy-efficient metro found in urban areas with zero heat consumption from external sources contains air ventilation systems of tunnels and station rooms and facilities, including heat pumps, which are separated by installing a separation fence with automatic doors. Moreover, the air ventilation system for tunnels contains reversible fans installed in shafts, wherein aid fans in shafts which are located in front of the train in motion and enter the pressure zone automatically switch to the exhaust air removal mode, and fans in ventilation shafts which are behind the train in the vacuum zone switch to the supply air supply mode.

EFFECT: technical result is to increase the energy efficiency of air ventilation systems of the metro.
