The energy-saving and energy-efficient electric heating system of a passenger car

One of the solutions to the issue of energy saving and energy efficiency in railway passenger transport is connected with the development of new innovative devices and electric heating systems that provide the comfortable temperature conditions for passengers. We consider one of the variants of an energy-saving and energy-efficient electric heating system based on the heat-generating electromechanical converter created on the basis of the stator of a conventional asynchronous motor. This converter combins the functions of a heating element and a device for moving the heated coolant. The device is designed for offline operation. The useful use of heating of the structural units of the device, which plays a negative role in a conventional electromechanical converter, leads to an increase in the efficiency of the device and the entire heating system. Based on thermal and hydraulic calculations we have developed a heating system and a layout the scheme of the selected elements in relation to a compartment passenger car.
