  • Patent number: 10676919
    Abstract: Two or more soundproof cells arranged in a two-dimensional manner are provided. At least one of the soundproof cells is a first soundproof cell configured to include a first frame having a first through-hole. At least one of the other soundproof cells is a second soundproof cell including a second frame having a second through-hole and a film fixed to the second frame.

  • 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: 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.

  • Publication number: 20190003780
    Abstract: A heat storage system includes an energy conversion portion, and a heat storage portion having a heat storage material. The energy conversion portion converts a form of an energy source into another form, and the energy conversion portion dissipates heat through a medium at the same time as the energy conversion. The heat storage material exchanges heat with the medium. The heat storage material stores heat from the medium in a heat storage mode, and the heat storage material dissipates the stored heat to a heating target. The heat storage material exhibits a first solid phase when a temperature of the heat storage material is higher than a predetermined temperature, and the heat storage material exhibits a second solid phase when the temperature of the heat storage material is at or lower than the predetermined temperature.

  • Publication number: 20180212290
    Abstract: A storage battery system includes a rechargeable storage battery and a solid heat storage portion. The solid heat storage portion is made of a heat storage material that reversibly undergoes a phase transition with absorption and release of a latent heat between a solid phase and a solid phase at a certain phase transition temperature. The heat storage material causes a solid phase to solid phase state phase transition when a temperature of the storage battery reaches the phase transition temperature to maintain the temperature of the storage battery at the phase transition temperature.
