Radiant panel with heat exchange device

An apparatus for heating or cooling a room of a building with a wall, the wall comprising an inner sheet facing the room and an outer sheet facing away from the room, the apparatus comprising:

• a radiant panel adapted to be supported on the wall, the radiant panel comprising:
• a first side adapted to face the wall;
• a second side which faces away from the wall and is adapted to radiate energy to or from a room;
• a fluid conduit configured for passage of a fluid;
• an inlet through which the fluid enters the radiant panel;
• and
• an outlet through which the fluid exits the radiant panel;
• a heat exchange device configured to heat or cool the fluid and adapted to be disposed substantially inside the wall;
• a first line connecting the inlet to the heat exchange device;
• a second line connecting the outlet to the heat exchange device;
• a pump that pumps the fluid that is heated or cooled by the heat exchange device through the first line, through the inlet, through the fluid conduit, through the outlet, and through the second line back to the heat exchange device, whereby the room is heated or cooled depending on whether the fluid is heated or cooled by the heat exchange device;
• spacing elements that set the radiant panel away from the interior sheet;
• a first air duct for bringing air from external to the building into the heat exchange device;
• a second air duct for directing air from the heat exchange device to the outside of the building;
• and
• a vent, whereby the heat exchange device exchanges energy from the room to the air external to the room through the vent;
• and
• wherein the radiant panel is adapted to be supported on the wall;
• wherein the heat exchange device is adapted to be mounted between two studs located between the inner sheet and the outer sheet.
