  • Publication number: 20220154977
    Abstract: The present invention relates to a close-contacting module capable of bringing a solar photovoltaic panel and a thermal collector of a solar photovoltaic-thermal panel into close contact without creating an interface. The close-contacting module comprises: a plurality of elastic members (36) which provide an elastic force that presses the thermal collector (20) toward the solar photovoltaic panel (10) from the backside of the thermal collector (20); a support member (35) for supporting the elastic members (36); and a pair of clips (31, 32, 33) provided at both ends of the support member (35) to fix the support member (35) to the edges of the solar photovoltaic-thermal panel (1).

  • Patent number: 9459012
    Abstract: Provided is a thermal energy network system including: a first thermal station that stores first thermal energy using a first heat source and supplies the first thermal energy to a first demand source used for residence or commerce; and a second thermal station that stores second thermal energy using a second heat source and supplies the second thermal energy to a second demand source used for industry, wherein the first thermal station and the second thermal station manage a base load of a thermal energy network, and the first thermal energy and the second thermal energy are transferred between the first thermal station and the second thermal station as needed.

  • Patent number: 9243616
    Abstract: A heat-electricity combined production system includes: a solar cell module in which a flow path through which a heat source side heating medium heated by solar heat flows, is formed and which generates electricity by solar light; a geothermal heat exchanger that absorbs geothermal heat through the heat source side heating medium; a heat pump including a heat source side heat exchanger that performs heat-exchange between the heat source side heating medium and a refrigerant and a load side heat exchanger that performs heat-exchange between the refrigerant and a load side heating medium; a controller that control the heat source side heating medium to pass through both the solar cell module and the geothermal heat exchanger; and a plurality of pipes that connect the solar cell module, the geothermal heat exchanger and the heat pump.
