  • Patent number: 10767538
    Abstract: An energy conversion device includes a first acoustic wave generator, a second acoustic wave generator, and an output unit which are provided in a pipe member. The first acoustic wave generator has a thermal energy generator configured to generate thermal energy from electric energy, and converts the thermal energy generated by the thermal energy generator into acoustic energy to generate acoustic wave in working gas by a self-excited thermo acoustic vibration. The second acoustic wave generator converts thermal energy supplied from a heat supply source into acoustic energy and generates acoustic wave in working gas by a self-excited thermo acoustic vibration. The output unit converts the acoustic energy of the acoustic waves from the first acoustic wave generator and the second acoustic wave generator into cold energy to output.

  • Publication number: 20200127305
    Abstract: An energy conversion system includes an energy converter, a cold generator, and a liquid water obtainer. The energy converter is configured to convert energy of a source from one form to another form and generate heat and water vapor. The cold generator is configured to generate cold using the heat generated by the energy converter. The liquid water obtainer is configured to condense the water vapor using the cold to obtain liquid water. Accordingly, the water vapor generated from the energy converter can be cooled efficiently. Therefore, efficiency in obtaining the liquid water can be improved compared with a case where the water vapor is cooled by open air.

  • Patent number: 10618373
    Abstract: A heat exchanger has (i) a first passage in which a first fluid flows, (ii) a heat storage body that is thermally connected to the first passage and stores a warm heat or a cold heat, and (iii) a second passage that is thermally connected to both of the first passage and the heat storage body, the second passage in which a second fluid flows. The heat storage body changes to a first phase in a solid state when a temperature of the heat storage body is lower than or equal to a phase transition temperature, and changes to a second phase in a solid state when the temperature of the heat storage body exceeds the phase transition temperature. The heat storage body stores or dissipates heat depending on a phase transition between the first phase and the second phase.

  • Patent number: 10502117
    Abstract: A heat storage system has a heat source that generates heat and releases the heat to a first heat medium and a heat storage body that stores heat. The heat storage body changes to a first phase in a solid state when a temperature of the heat storage body is lower than or equal to a phase transition temperature, and changes to a second phase in a solid state when a temperature of the heat storage body exceeds the phase transition temperature. The heat storage body stores or releases heat due to a phase transition between the first phase and the second phase. A mode of operation of the heat storage body is switchable between a heat storage mode in which the heat storage body stores heat of the first heat medium and a heat release mode in which the heat storage body releases the heat stored in the heat storage body to a heat transfer target.

  • Patent number: 10377937
    Abstract: A heat transfer system has an energy converter, a heat transfer medium, a transfer part, and a heat exchanger. The energy converter converts an energy of an energy source into an energy in a different state and generates a heat while converting the energy. The heat transfer medium is in a liquid state and receives the heat from the energy converter. The heat exchanger dissipates the heat from the heat transfer medium to an outside of the heat transfer system. The heat transfer medium contains H2O and a solute compatible with the H2O. The solute has a molecular structure including two hydroxyl groups. A length of a binding chain between an oxygen atom of one of the two hydroxyl groups and an oxygen atom of an other of the two hydroxyl groups is shorter than a length of a binding chain between two hydroxyl groups of an ethylene glycol molecule.

  • Patent number: 10279657
    Abstract: An energy management system is applied to a vehicle having a first power source, a first converter, an electricity storage part, and a second power source. The energy management system has a second converter, a heat storage part, a mode switching part, and a controller. The mode switching part switches between a heat storage mode and a heat radiation mode. The heat storage part changes to a first phase in a solid state when a temperature of the heat storage part is lower than or equal to a phase transition temperature, and changes to a second phase in a solid state when a temperature of the heat storage part exceeds the phase transition temperature. The controller controls the operations of the second converter and the mode switching part based on at least one of an electricity storage condition of the electricity storage part and a conversion condition of the first converter.

  • Publication number: 20190032979
    Abstract: During a normal operation, a refrigeration cycle device is switched to a refrigerant circuit in which heat contained in a high-pressure refrigerant flowing out of an interior radiator is stored in a heat storage member. When frost is formed on an evaporator, the refrigeration cycle device is switched to another refrigerant circuit in which the exterior heat exchanger is heated and defrosted using heat stored in the heat storage member as a heat source. The heat storage member uses a material formed by adding W (tungsten) as an additive to VO2 (vanadium dioxide) which is a transition metal oxide having a property of a phase transition between a metal and an insulator. The heat storage member effectively stores or dissipates heat depending on a temperature zone of the refrigerant, thereby suppressing an increase in energy consumption of a compressor.

    Abstract: A magneto-caloric-effect element has a plurality of element units. The element units have lengths, respectively. The element units have different Curie temperatures, respectively. The element units demonstrate magneto-caloric effects. Two adjoining performance distribution crosses at a cross temperature. A temperature in the rated operational status between two adjoining element units is called a boundary temperature. The lengths and/or Curie temperatures are set so that the boundary temperatures and the cross temperatures coincide each other. Thereby, a plurality of element units can function at high effectiveness in the rated operational status.
