Abstract: Radiant heat transfer in real enclosure with diffuse emission and specular reflection surfaces has been studied by the Monte Carlo method. Radiation exchange factors of radiant cooler have been calculated by Monte Carlo method. The flow chart of computer program is described and the calculated results are discussed.
