  2. Radiant heating and cooling - Wikipedia

    en.wikipedia.org/wiki/Radiant_heating_and_cooling

    Radiant heating and cooling. Radiant heating and cooling is a category of HVAC technologies that exchange heat by both convection and radiation with the environments they are designed to heat or cool. There are many subcategories of radiant heating and cooling, including: "radiant ceiling panels", [1] "embedded surface systems", [1] "thermally ...

  3. Radiative cooling - Wikipedia

    en.wikipedia.org/wiki/Radiative_cooling

    The three basic types of radiant cooling are direct, indirect, and fluorescent: Direct radiant cooling - In a building designed to optimize direct radiation cooling, the building roof acts as a heat sink to absorb the daily internal loads. The roof acts as the best heat sink because it is the greatest surface exposed to the night sky.

  4. Thermal radiation - Wikipedia

    en.wikipedia.org/wiki/Thermal_radiation

    Personalized cooling technology is an example of an application where optical spectral selectivity can be beneficial. Conventional personal cooling is typically achieved through heat conduction and convection. However, the human body is a very efficient emitter of infrared radiation, which provides an additional cooling mechanism.

  5. Radiant energy - Wikipedia

    en.wikipedia.org/wiki/Radiant_energy

    Visible light such as sunlight carries radiant energy, which is used in solar power generation. In physics, and in particular as measured by radiometry, radiant energy is the energy of electromagnetic [1] and gravitational radiation. As energy, its SI unit is the joule (J). The quantity of radiant energy may be calculated by integrating radiant ...

  6. Passive daytime radiative cooling - Wikipedia

    en.wikipedia.org/wiki/Passive_daytime_radiative...

    Passive daytime radiative cooling (PDRC) (also passive radiative cooling, daytime passive radiative cooling, radiative sky cooling, photonic radiative cooling, and terrestrial radiative cooling[2][3][4][5]) is the use of unpowered, reflective/ thermally-emissive surfaces to lower the temperature of a building or other object. [6]

  7. Solar energy - Wikipedia

    en.wikipedia.org/wiki/Solar_energy

    A heat pump is a device that provides heat energy from a source of heat to a destination called a "heat sink". Heat pumps are designed to move thermal energy opposite to the direction of spontaneous heat flow by absorbing heat from a cold space and releasing it to a warmer one.

  8. Climate model - Wikipedia

    en.wikipedia.org/wiki/Climate_model

    Climate models are systems of differential equations based on the basic laws of physics, fluid motion, and chemistry. To "run" a model, scientists divide the planet into a 3-dimensional grid, apply the basic equations, and evaluate the results. Atmospheric models calculate winds, heat transfer, radiation, relative humidity, and surface ...

  9. Mean radiant temperature - Wikipedia

    en.wikipedia.org/wiki/Mean_radiant_temperature

    Mean radiant temperature. The concept of mean radiant temperature (MRT) is used to quantify the exchange of radiant heat between a human and their surrounding environment, with a view to understanding the influence of surface temperatures on personal comfort. Mean radiant temperature has been both qualitatively defined and quantitatively ...
