  2. Thermal transmittance - Wikipedia

    en.wikipedia.org/wiki/Thermal_transmittance

    Losses due to thermal radiation, thermal convection and thermal conduction are taken into account in the U-value. Although it has the same units as heat transfer coefficient , thermal transmittance is different in that the heat transfer coefficient is used to solely describe heat transfer in fluids while thermal transmittance is used to ...

  3. Heat transfer - Wikipedia

    en.wikipedia.org/wiki/Heat_transfer

    Radiation from the sun, or solar radiation, can be harvested for heat and power. [17] Unlike conductive and convective forms of heat transfer, thermal radiation – arriving within a narrow-angle i.e. coming from a source much smaller than its distance – can be concentrated in a small spot by using reflecting mirrors, which is exploited in ...

  4. Thermal conductance and resistance - Wikipedia

    en.wikipedia.org/wiki/Thermal_conductance_and...

    It quantifies how effectively a material can resist the transfer of heat through conduction, convection, and radiation. It has the units square metre kelvins per watt (m 2 ⋅K/W) in SI units or square foot degree Fahrenheit–hours per British thermal unit (ft 2 ⋅°F⋅h/Btu) in imperial units. The higher the thermal insulance, the better a ...

  5. Thermal radiation - Wikipedia

    en.wikipedia.org/wiki/Thermal_radiation

    Radiation waves may travel in unusual patterns compared to conduction heat flow. Radiation allows waves to travel from a heated body through a cold non-absorbing or partially absorbing medium and reach a warmer body again. [14] An example is the case of the radiation waves that travel from the Sun to the Earth.

  6. R-value (insulation) - Wikipedia

    en.wikipedia.org/wiki/R-value_(insulation)

    The R-value is a measure of an insulation sample's ability to reduce the rate of heat flow under specified test conditions. The primary mode of heat transfer impeded by insulation is conduction, but insulation also reduces heat loss by all three heat transfer modes: conduction, convection, and radiation.

  7. Blue screen of death - Wikipedia

    en.wikipedia.org/wiki/Blue_screen_of_death

    BSoDs in the Windows NT family initially used the 80×50 text mode with a 720×400 screen resolution, but changed to use the 640×480 screen resolution starting with Windows 2000 up to 7. Windows 2000 used its built-in kernel mode font, Windows XP, Vista, and 7 use the Lucida Console font, and Windows 8 and Windows Server 2012 used the Segoe UI ...

  8. Radiant heating and cooling - Wikipedia

    en.wikipedia.org/wiki/Radiant_heating_and_cooling

    Fireplaces and woodstoves A fireplace provides radiant heating, but also draws in cold air. A: Air for the combustion, in drafty rooms pulled from the outdoors. B: Hot exhaust gas heats building by convection as it leaves by chimney. C: Radiant heat, mostly from the high temperature flame, heats as it is absorbed

  9. List of features removed in Windows 10 - Wikipedia

    en.wikipedia.org/wiki/List_of_features_removed...

    Windows 10 is a version of Windows NT and the successor of Windows 8.1. Some features of the operating system were removed in comparison to Windows 8 and Windows 8.1, and further changes in features offered have occurred within subsequent feature updates to Windows 10. Following is a list of these.
