The world’s largest construction with floor cooling is the new airport in bangkok3 figure 5: installation of floor cooling with manifolds in the displacement diffusers at the new bangkok airport the roof over the concourses (figures 4 and 5) consists of glass and a plastic membrane construction. Radiant cooling system can be also used for heating 11 november 2011 ©uponor 7 2,5 m thermal comfort zone (high ceilings) an a/c system changes all air volume in a room bangkok international airport 11 november 2011 ©uponor 20 reconstruction of a historical building from 1880. Radiant floor cooling combined with displacement ventilation is used in the new bangkok airport, whose innovative design concept is described in some recent papers [3,27,28].
Meters in europe, bangkok airport, and many thousands of sf in the us and canada now they are a mix of radiant floors and ceilings most of the radiant cooling systems i design are radiant ceilings (heating/cooling), however there are many radiant floor cooling systems operating in the us right now as well. The radiant floor cooling system in suvarnabhumi international airport in bangkok, thailand (hereinafter referred to as bangkok airport) was dimensioned to remove 70–80 w/m 2 of heat, and the radiant floor could absorb up to 50 w/m 2 by radiation. Bangkok’s climate has temperatures from 25°c–30°c, a high level of relative humidity and solar radiation, and solar altitudes near the zenith an international airport requiring a constant air temperature (24°c) and 50–60% relative humidity, calls for continual cooling and dehumidification. Displacement ventilation has been applied in many famous building such as the suvarnabhumi international airport in bangkok, thailand, the nasa jet propulsion laboratory flight projects center pairing displacement ventilation with radiant chilled ceilings is an effort to mitigate this calculate summer design cooling load.
