  • Patent number: 11441315
    Abstract: In a first aspect, a system for heating, cooling, or both heating and cooling a room is disclosed. The system includes a panel with a first, second, and third wall. The second wall is disposed between the first and third walls and separated by a plurality of partitions. The partitions create a first and second row of elongated channels. Each channel in the first row is bounded on two sides by two partitions and on two other sides by the first and second walls. Each channel in the second row is bounded on two sides by two partitions and on two other sides by the second and third walls. The first row of channels is a fluid layer configured to allow heated or cooled fluid to pass through. The fluid layer is in thermal communication with the room. The second row of channels is an insulating vacuum layer, with a reduced pressure that is at least 20% less than atmospheric pressure.

  • Patent number: 11300303
    Abstract: The invention is an apparatus for heating or cooling a room of a building. The apparatus includes a radiant panel supported on a wall, which radiates energy to or from a room. The radiant panel has a conduit for passage of a fluid. The invention also includes a heat exchange device which heats or cools the fluid, which is installed inside the wall between two studs. A first line and second line connect the inlet and outlet to the heat exchange device. A pump that pumps the fluid that is heated or cooled by the heat exchange, whereby the room is heated or cooled depending on whether the fluid is heated or cooled by the heat exchange device.

  • Publication number: 20210148586
    Abstract: The invention is, in one aspect, a system for heating or cooling a room, including a radiant panel with fluid conduit, which, radiates energy to a room. A heat exchange device exchanges energy between the fluid in the radiant panel and an exchange medium. A vent allows fresh air to enter a room, moved by a fan. The fan propels the air through a chamber for heating or cooling the air, wherein the chamber at least partially comprises the radiant panel.

  • Publication number: 20210120635
    Abstract: The invention is a heating and display mirror. The mirror is composed of two different “zones”, one for heating and one for display. The heating zone is heated by radiant heat, and the display zone features a display device that produces lighted images visible on the mirror's surface. The heating and display zones are operated by user controls, which give instructions to the heating zone to turn on and off, and to the display zone regarding what images to display on the lighted display device.

  • Publication number: 20210102717
    Abstract: An apparatus for heating or cooling a room of a building with an exterior wall includes a radiant panel supported on an exterior wall, which includes a fluid conduit for passage of a fluid. The fluid enters through an inlet and exits through an outlet of the radiant panel and goes through a transmission tube and into a heat exchanger, which is located on the exterior side of the wall. The fluid then flows through the transmission tube and enters the inlet of the radiant panel.
