Radiant heat exchange calculations in radiantly heated and cooled enclosures.

Author(s) : CHAPMAN K. S.

Summary

A three-dimensional mathematical model was developed to compute the radiant heat exchange between surfaces separated by a transparent and/or opaque medium. The model accommodates arbitrary arrangements of the interior surfaces as well as arbitrary placement of obstacles within the enclosures. The three-dimensional model based on the discrete ordinates method can be applied to the sizing of a radiant heating system. By coupling this model with a convective and conductive heat transfer model and a thermal comfort model, the comfort levels throughout the room can be easily and efficiently mapped for a given radiant heater location.
