  • Cogeneration system
    Patent number: 5819843
    Abstract: A cogeneration system includes a gas engine generator acting as private power generating equipment for generating power to be supplied to private electricity consuming equipment, and a source-side heat exchanger connected to the gas engine generator through an exhaust heat recovery piping to act as a heat source. A heat medium is heated and evaporated through a heat exchange in the source-side heat exchanger. The resulting vapor is allowed to flow upward to be supplied to room heating heat exchangers. The vapor is liquefied through a heat exchange in the room heating heat exchangers. The resulting liquid is allowed to flow downward back to the source-side heat exchanger. This natural circulation of the heat medium is used for the heating purpose. Surplus exhaust heat is released through a generator to control the heat medium supplied to the room heating heat exchangers.
    Type: Grant
