Definitions

  • the present invention relates to a heating system. More particularly this invention concerns a heater for a passenger or driver compartment of a train car.
  • the object of the present invention is to use the generated waste heat of a railroad car for heating the passenger compartment and/or the driver's cab of the car.
  • a system for heating a compartment of a rail car having a heat-generating engine with a cooling-water system has system has according to the invention a heat pump having a compressor, a condenser, an evaporator, and an expansion valve connected in a closed circuit, and a waste-air fan and ductwork feeding a stream of gas carrying waste heat generated by or in the rail car through the evaporator.
  • waste heat is not applied directly to the stream of air fed into the compartment to cool it, but is used to raise the heat-pump temperature in general.
  • the rail car has a motor with a water-cooling system.
  • the system further has a radiator juxtaposed with the condenser and connected in the water-cooling system of the motor, and a fan in the heat pump blowing air through the radiator and the condenser.
  • This radiator is between the condenser and the fan of the heat pump.
  • FIG. 1 is a schematic diagram of the heating system of this invention.
  • FIG. 2 is a view like FIG. 1 , but with an additional air line connected to the evaporator of the heat pump and through of which the waste heat is vented from the rail car.
  • a heat pump 1 has a compressor 8 that compresses a gaseous heat-exchange fluid and feeds it under high pressure when operating as a heater to an internal heat exchanger 2 acting as a condenser.
  • a fan 6 blows air through the condenser 2 so that heat from the compressed heat-exchange agent is transferred to the passing air that then is fed into a passenger compartment 14 while simultaneously liquefying the heat-exchange fluid.
  • the heat-exchange fluid While still a liquid and pressurized, the heat-exchange fluid passes through an expansion valve 10 that abruptly drops its pressure. This not only results in a temperature reduction of the heat-exchange fluid, but also gasifies it.
  • the gasified and cooled heat-exchange medium then passes through an external heat exchanger 3 acting as evaporator. In the evaporator, the heat-exchange agent is warmed by ambient air passed through it by a fan 7 until it is completely evaporated.
  • a separate heat exchanger or radiator 4 is provided immediately upstream of the internal heat exchanger 2 in the direction of air flow through it from the fan 6 to receive heat therefrom, that is between the upstream side of the condenser 2 and the fan 6 .
  • This radiator 4 is connected in the cooling-water system used to heat the two electric motors 5 of the rail car 15 .
  • the waste heat from the motors 5 at least is therefore also used to heat the condenser 2 and the rail-car compartment.
  • the waste heat is utilized as a result of the integration of the separate cooling water heat exchanger 4 that operates independently from the circuit of the heat pump 1 .
  • standard engine cooling liquids is typically mainly water, are used as the heat-exchange fluid or medium to carry energy.
  • cool fresh or cool mixed air is sucked in by the fan 6 and is passed through both heat exchangers 2 and 4 . If sufficient waste heat from the engine is available, the air can be heated only via the cooling water heat exchanger 4 and can be blown into the passenger compartment 14 .
  • the heat pump 1 and thus the internal heat exchanger 2 acting as condenser can be switched off and therefore remain without function.
  • the cooling water heat exchanger 4 is provided in the feed air flow upstream of the condenser 2 . The reason for this is that, if not enough waste heat from the engine is available, the heat pump 1 is also operated in order to heat the air preheated by the cooling water heat exchanger 4 to the desired temperature before entering the condenser 2 .
  • the waste heat of many subsystems can be used. Apart from the existing waste heat, also a stream 11 of warm air from the compartment 13 of the rail car 14 can be used and its thermal energy can be recovered. Also a combination from both sources is possible.
  • the heat pump 1 takes over the heating of the feed air on its own by the condenser 2 , and the cooling-water heat exchanger 4 remains without function.
  • the cooling water heat exchanger 4 can also be used as an anti-freezing protector for the internal heat exchanger 2 in this case serving as evaporator during air conditioning operation. As a result, the use of an energy-intensive bypass as anti-freezing protection is not necessary.
  • a stream 12 of hot air carrying waste heat is passed through the heat exchanger 3 of the heat pump 1 , so its thermal energy is initially transferred to the heat-exchange medium in the heat pump 1 , as a result of which the temperature level is increased even further.
  • the air ducts that carry the waste heat to the outside heat exchanger 3 during heat-pump operation may be provided with flaps 13 , so that during air conditioning operation, the waste heat does not go to the outside heat exchanger or condenser 3 .
  • energy-intensive anti-freezing protection can also be overridden or greatly reduced when ambient temperatures are low.
  • an electric heater may be provided, e.g. an electrically powered resistive heating coil.
