3940 (RP-657) -- Energy Transfer Simulation for Radiantly Heated and Cooled Enclosures PDF

Presents the development of a three-dimensional mathematical model to compute the heat transfer within a radiantly heated or cooled room, which then calculates the mass-averaged room air temperature and the wall surface temperature distributions. States the model may be applied to a building to assist the heating/cooling design engineer size a radiant heating/cooling system. By coupling the model with a thermal comfort model, the comfort levels throughout the room can be easily and efficiently mapped for a given radiant heater/cooler location. In addition, obstacles such as aeroplanes, trucks, furniture and partition as can be easily incorporated to determine their effect on the radiant system performance.
