Influence of asymmetric radiation on heat exchange of planar radiant air conditioning and its correction

In this paper, the influence of radiation asymmetry on radiant heat transfer in the room of plane radiant air-conditioning system is analyzed. The radiation heat transfer model used in the Fanger thermal comfort equation is introduced. Using Airpak simulation analysis, it is concluded that external Windows and external walls should be taken as separate enclosure structures to calculate the PMV value. A new radiation heat transfer model was established, and the radiation heat transfer was solved under the new radiation heat transfer model. As the radiation heat transfer in the PMV equation, the thermal comfort equation was modified. (paper)
