Abstract:The EHT (equivalent homogenous temperature) was calculated by using the coupling model of CFD and human thermoregulation model. The effects of air conditioning velocity, temperature, and solar radiation on overall EHT， mean skin temperature, and dry heat loss were compared, and the contribution ratio of the these factors were calculated. The results show that the influence of air conditioning is greater than that of solar radiation, in which the influence of the supply air temperature is most significant. Finally the fitting equation of the three factors and EHT were obtained, and a new idea to improve air conditioning controlling based on the fitting equation was proposed.
