Simplified Calculation Method for Indoor Mean Radiant Temperature in High-temperature Heat Source Buildings
The strong radiant heat generated by high-temperature heat sources will have a significant impact on the health and production efficiency of workers in steel plants,metallurgical plants and other buildings.However,due to the shielding of heat sources and the complexity of building surfaces,there is currently a lack of simplified methods for calculating indoor mean radiant temperature that can assess high=temperature radiation environments.In this paper,indoor mean radiant temperature in high-temperature heat source buildings was calculated with a simplified method and measured by field test,respectively.The results showed that the maximum relative error between calculated and measured indoor mean radiant temperature was 21.5％with a block-shaped heat source and 8％with a strip-shaped heat source,so the proposed method could be applied in practical engineering.
