Indoor thermal environment characteristics based on solar radiation

 Through experimental test and theoretical calculation, comprehensively analyses the variation law of indoor thermal environment characteristics influenced by solar radiation from the aspects of mean radiant temperature and actual thermal sensibility vote, and analyses the calculation method of mean radiant temperature under this condition. Puts forward the problems existing in air conditioning zoning at present, and studies a more detailed method of air conditioning zoning. The results show that the indoor thermal environment is unevenly distributed with the influence of solar radiation, and the wall temperature, space temperature and mean radiant temperature are closely related to the solar irradiance. The PMV calculated by the theoretical value of the mean radiant temperature in the radiation region is basically consistent with the actual thermal sensation voting value of the human body. So when the indoor environment is affected by solar radiation, the method using the black globe radiation temperature to convert the mean radiant temperature is not reasonable, and the theoretical calculation value can be used to evaluate the indoor thermal environment more accurately. Suggests dividing the building more carefully on the basis of the division of the inner and outer zones, so as to control the instantaneous load of different areas of the building in real time, in order to achieve the purpose of thermal comfort and energy saving.
