FIELD: railway transport. ^ SUBSTANCE: proposed system comprises closed-circuit heat supply circuitwith pipeline (2), radiators (3), automatic control system, ACS power supply and heat generator (1) running on vortex-type direct fluid power conversion principle. Heat generator comprises inlet branch pipe, outlet branch pipes, centrifugal pump and is arranged below aforesaid closed-circuit heat supply circuit, in particular under car bottom to drive centrifugal pump shaft from the car wheel pair axle. Heat generator outlet branch pipes represent two tangential opposed branch pipes with solenoid valves (14, 15) connected to aforesaid closed-circuit heat supply circuit. ^ EFFECT: higher efficiency, safety and reliability; reduced power consumption and overall dimensions. ^ 2 cl, 2 dwg |
