Hydronic radiant floor heating systems use a boiler or district heating to heat water and a pump to circulate the hot water in plastic pipes installed in a concrete slab. The pipes, embedded in the floor, carry heated water that conducts warmth to the surface of the floor, where it broadcasts heat energy to the room above.
Pairing displacement ventilation with radiant chilled ceilings is an effort to mitigate this problem. [12] According to some studies, displacement ventilation systems can only provide acceptable comfort if the corresponding cooling load is less than about 13 Btu/h-sf or 40 W/m 2 .
Local discomfort caused by floor temperature and radiant temperature asymmetry should be measured at the floor surface and at the occupants’ locations, respectively. [ 12 ] The standard suggests that the time of measurements should last two or more hours long, and it should also be a representative time of the year for this specific building.
radiant floor A type of radiant heating system where the building floor contains channels or tubes through which hot fluids such as air or water are circulated. The whole floor is evenly heated. Thus, the room is heated from the bottom up. Radiant floor heating eliminates the draft and dust problems associated with forced air heating systems ...
Radiant heating and cooling originated as separate systems but now share a similar form. Radiant heating has a long history in Asia and Europe. The earliest systems, from as early as 5000 BC, were found in northern China and Korea. Archaeological findings show kang and dikang, heated beds and floors in ancient Chinese homes. Kang originated in ...
He then took the same idea to create a heating system that fits American houses. Wright invented modern radiant floor heating, using hot water running through pipes instead of hot air through flues. [5] A heating film, itself, is a variation of the modern ondol, but it doesn't require hot water and pipes as it is fully electric.
