Cooling by radiation
WebRadiation fog is a very common type of fog throughout the United States. It is most prevalent during the fall and winter. It forms overnight as the air near the ground cools and stabilizes. When this cooling causes the air to … WebRadiation cooling of electronic components and boxes is not usually a concern to thermal engineers. The three factors that affect cooling by radiation are: the temperature difference between an object and its surroundings, the surface characteristics of the object and its surroundings, and the view that the object has of its surroundings ...

Web@article{osti_6802688, title = {Cooling by longwave radiation}, author = {Givoni, B}, abstractNote = {Theoretical and experimental studies are summarized in a review, and the design options for using radiant cooling are evaluated. The various components involved in the radiant exchange of longwave (nocturnal) radiation between radiators and the … WebRadiation is the transfer of heat through electromagnetic waves through space. Unlike convection or conduction, where energy from gases, liquids, and solids is transferred by the molecules with or without their physical movement, radiation does not need any medium (molecules or atoms). Energy can be transferred by radiation even in a vacuum.
Mechanism Infrared radiation can pass through dry, clear air in the wavelength range of 8–13 µm. Materials that can absorb energy and radiate it in those wavelengths exhibit a strong cooling effect. Materials that can also reflect 95% or more of sunlight in the 200 nanometres to 2.5 µm range can exhibit … See more In the study of heat transfer, radiative cooling is the process by which a body loses heat by thermal radiation. As Planck's law describes, every physical body spontaneously and continuously emits electromagnetic radiation See more Climate change The widespread application of passive daytime radiative cooling (PDRC) technologies that … See more • Heat shield • Optical solar reflector, used for thermal control of spacecraft • Passive cooling • Radiative forcing • Stefan–Boltzmann law See more WebThere are three forms of thermal energy transfer: conduction, convection, and radiation.

WebThe re-radiation of heat is affected by the concentration of greenhouse gases. Additionally, the coverage and distribution of clouds, both vertically and horizontally, can have opposite influences on Earth’s climate. Thin, high clouds, such as cirrus clouds, are colder than the surface of the Earth and absorb outgoing heat, resulting in less ... http://large.stanford.edu/courses/2015/ph240/burnett1/
