2. Radiant heating and cooling - Wikipedia

   en.wikipedia.org/wiki/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 active building systems ...

3. Central heating - Wikipedia

   en.wikipedia.org/wiki/Central_heating

   In a steam heating system, each room is equipped with a radiator which is connected to a source of low-pressure steam (a boiler). Steam entering the radiator condenses and gives up its latent heat, returning to liquid water. The radiator in turn heats the air of the room, and provides some direct radiant heat. The condensate water returns to ...

4. 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.

5. Heating, ventilation, and air conditioning - Wikipedia

   en.wikipedia.org/wiki/Heating,_ventilation,_and...

   Most modern hot water boiler heating systems have a circulator, which is a pump, to move hot water through the distribution system (as opposed to older gravity-fed systems). The heat can be transferred to the surrounding air using radiators, hot water coils (hydro-air), or other heat exchangers. The radiators may be mounted on walls or ...

6. Thermal radiation - Wikipedia

   en.wikipedia.org/wiki/Thermal_radiation

   Radiant heat panel for testing precisely quantified energy exposures at National Research Council, near Ottawa, Ontario, Canada. Thermal radiation plays a crucial role in human comfort, influencing perceived temperature sensation. Various technologies have been developed to enhance thermal comfort, including personal heating and cooling devices.

7. Window film - Wikipedia

   en.wikipedia.org/wiki/Window_film

   Ceramic window films cost slightly more but provide a substantial increase by reflecting and absorbing infrared radiation (IR or radiant heat). To keep the sun's heat out of the house, a low-emissivity coating should be applied to the outside pane of glazed windows. If the windows are designed to provide heat energy in the winter and keep heat ...
