Abstract
A radiant cooling system comprises an enclosure, a cooling element and a cooling device. The enclosure includes a first wall that is transmissive of infrared radiation. The cooling element is disposed in the enclosure. The cooling device is coupled to the cooling element. The cooling element provides cooling mainly by radiative exchange. The system promotes cooling by radiative exchange and significantly reduces condensation problems and is compatible with open and enclosed spaces. Thermal losses of cooling power to conductive and convective pathways are significantly reduced. The system comes in a variety of forms including flat, cylindrical and dome-like geometries.
Claims14
A radiant cooling system comprising:
- an enclosure including:
- a bottom wall that is at least partially transmissive of infrared radiation, and
- a top wall having an inside surface with an emissivity below 0.1;
- a cooling element disposed inside the enclosure, between the bottom wall and the top wall of the enclosure;
- a cooling device coupled to the cooling element, the cooling device being outside the enclosure;
- insulation disposed outside the enclosure adjacent to the top wall and a ceiling of a room that houses the enclosure;
- and
- a light engine disposed on a bottom side of the cooling element,
- wherein the enclosure is at least partially transmissive of the infrared radiation from an outer side of the bottom wall to an inner side of the of the bottom wall,
- wherein the enclosure is a vacuum chamber,
- wherein the cooling element is operational at a temperature below a dew point within the room that houses the enclosure, and
- wherein the top wall of the enclosure is mountable to the ceiling of the room such that the insulation, which is disposed outside of the enclosure and adjacent to the top wall of the enclosure, is in direct contact with the ceiling and such that output of the light engine is directed away from the ceiling of the room.
