Aeraulic device and radiant ceiling thermal system with internal air mixing

A radiant ceiling thermal system for heating and cooling of an internal room, wherein the internal room includes an upper volume or plenum, the system comprising:

• a plurality of radiant panel connectable together to form a radiant false ceiling;
• at least two openings formed in the radiant false ceiling and configured to place the internal room in fluid communication with the upper volume or plenum;
• and
• at least one aeraulic device configured to be arranged in the upper volume or plenum of the internal room above the radiant false ceiling, the at least one aeraulic device comprising:
• a case body having an inlet opening and an outlet opening;
• and
• at least one fan housed by said case body and configured to move an airflow between said inlet opening and said outlet opening;
• wherein said inlet opening and said outlet opening are configured in fluid connection with the internal room and with the upper volume or plenum of the internal room;
• and
• wherein said inlet opening and said outlet opening are configured to be in cooperation with the at least two openings of the radiant false ceiling such that said at least one fan is positioned to generate a flow of air mixing between the internal room and the upper volume or plenum of the internal room;
• and
• wherein the at least one aeraulic device is arranged above said radiant false ceiling between the internal room and the upper volume or plenum;
• and
• wherein said at least one aeraulic device is configured to circulate air within the internal room through said at least two openings of the radiant false ceiling.
