Proposal for a heat balance model tailored to the Korean peninsula

Abstract

This study proposes a model that estimates optimal expected temperature for thermal comfort at various levels of relative humidity, wind speed, mean radiation temperature, metabolic rate, and clothing insulation, while improving the variables of the mean radiation temperature. By including the results of numerical and observational data testing, the improved model considers mean radiant temperatures more comprehensively than the previous model. Changes in expected temperatures for thermal comfort at various mean radiation temperatures showed that the outdoor temperature must decrease as the length of outdoor exposure increases. The expected temperature for thermal comfort must be lower at higher metabolic rates. The expected temperature does not change as wind speed increases when the mean radiant temperature is low. However, as mean radiant temperature increases, the expected temperatures change depending on the wind speed.
