Definitions

  • the subject of the present invention is a method for converting low temperature thermal energy into high temperature thermal energy and mechanical energy and a heat pump device for such conversion.
  • Heat pumps known in the art make use of the evaporation and condensation phenomena, where a working medium passes through two states of aggregation. This process enables extracting thermal energy from a lower temperature location and transferring this energy to a higher temperature location.
  • a Japanese Patent No. JP2010096429 discloses a heat pump system which uses waste heat and improves COP efficiency coefficient by recovering enthalpy of a refrigerant on the high pressure side of a compressor and using the enthalpy to operate an absorption type heat pump circuit, while using waste heat of a prime mover as a heat source of a regenerator.
  • the method for converting low temperature thermal energy into high temperature thermal energy and mechanical energy consists in that a compressor and a water pump are driven by a heat engine operating in a closed circuit which is supplied with a part of the thermal energy extracted by a heat pump from a low temperature thermal energy source, said compressor being driven by an externally-supplied engine in the start-up phase.
  • a heat engine supplied with high temperature thermal energy is used as the start-up engine.
  • the working medium is passed through three states of aggregation. The same working medium is used in both the heat pump circuit and in the thermodynamic circuit of the heat engine which drives that heat pump .
  • Another invention described herein is a heat pump.
  • a source of low temperature thermal energy is connected through a water pump to a cold heat exchanger and an exchanger which stabilizes the temperature of the working medium.
  • a pressurized working medium tank is connected, via a cut-off valve, to a nozzle at the cold heat exchanger.
  • the cut-off valve is also connected to a check valve, and the chamber of the heat exchanger is connected, via a heating exchanger, to the inlet of the chamber of the first cylinder of the compressor.
  • the outlet of this compressor cylinder is connected, through a first exchanger of the heat exchanger, to the inlet of the second compressor cylinder.
  • the outlet of the second compressor cylinder is connected, through the hot heat exchanger of the heat engine and the second exchanger of the hot heat exchanger, to the inlet of the heat pump cold exchanger which is connected to the check valve of the working medium tank through cooling exchangers, cold exchanger of the heat engine and a condensing exchanger.
  • a first control valve is located between the check valve and the nozzle of the cold heat exchanger, said control valve controlling the whole device by regulating the amount of the working medium directed to the nozzle.
  • a second control valve is located between the outlet of a compressor cylinder and the second exchanger of the hot heat exchanger.
  • a third control valve is located between the cooling exchangers of the cold heat exchanger. The latter two valves control the operation of the heat engine.
  • T-pipes which direct water stream to the exchangers.
  • the compressor and the water pump are coupled with the start-up engine and the drive shaft of the heat engine or with the heat engine shaft only, and a power receiving device is connected to the heat engine drive shaft.
  • the heat pump according to the present invention increases the efficiency of a heat engine operating in a closed circuit, since it utilizes the thus far unused waste energy, not utilized in the thermodynamic circuit of that engine.
  • the heat pump recycles that waste energy to its thermodynamic circuit.
  • Compressor 1 and thermal pump 4 are driven by a heat engine 3 which operates in a closed circuit which is supplied with a part of the thermal energy extracted by the heat pump from a low temperature thermal energy source 6, said compressor being driven by an electric motor 2 in start-up phase.
  • the working medium is passed through three states of aggregation.
  • the same working medium is used in both the heat pump circuit and the thermodynamic circuit of the heat engine which drives that heat pump.
  • the medium is conveyed by compressor 1 through cold heat exchanger 7 of that pump and condenses to form liquid condensate which is pumped into pressurized tank 9 through check valve 13.
  • Figure 1 shows a schematic view of an exemplary embodiment of the heat pump according to the present invention.
  • a two-stage water-cooled compressor and pump 1 is coupled with a start-up electric engine 2 which is coupled with a Stirling heat engine 3.
  • the Stirling engine 3 is connected to a water pump 4 and a power generator 5.
  • a source of low temperature thermal energy 6 is connected through the water pump 4 to a cold heat exchanger 7 and an exchanger 8 which stabilizes the temperature of the working medium.
  • a pressurized working medium tank 9 is connected, via a cut-off valve 10, to a nozzle 11 of the cold heat exchanger 7.
  • the cut-off valve 10 is connected through a safety valve 12 to a check valve 13, and the internal chamber of a cold heat exchanger 14 is connected, via a heating exchanger 15 and an outlet 16, to the inlet of the chamber of the first cylinder 17 of the compressor 1.
  • the outlet of this cylinder 17 is connected, through a first exchanger 18a of a hot heat exchanger 18, to the inlet of the second cylinder 19 of the compressor 1.
  • the outlet of the second cylinder 19 of the compressor 1 is connected, through the hot heat exchanger 20 of the Stirling heat engine 3 and the second exchanger 18b of the hot heat exchanger 18, to the inlet 21 of the cold exchanger 7 of the heat pump, which is connected to the check valve 13 of the working medium tank, through cooling exchangers 22 and 23, a cold exchanger 24 of the Stirling heat engine 3 and a condensing exchanger 25.
  • a control valve 26 which controls the whole device by regulating the amount of the working medium directed to nozzle 11.
  • a second control valve 27 is located between the outlet of the cylinder 19 of the compressor 1 and the second exchanger of the hot heat exchanger 18.
  • a third control valve 28 is located between the cooling exchangers 23 and 25 of the cold heat exchanger 7. The two latter control valves control the operation of the heat engine.
  • T-pipes 29 and 30 Located between the low temperature energy source 6 and the cold exchanger 7 are T-pipes 29 and 30 which direct water stream to the exchangers 7 and 8.
