Summary

Radiant panel cooing system has attracted a great concern in engineering design and research due to its advantages of comfort and energy saving. This article studies the variations of indoor air temperature, room wall temperature, human body surface temperature in ceiling cooling room by experiment. The variation roles of convection and radiation heat transfer between human body and the environment at ceiling cooling room are analyzed. The results show that, in the 60 minutes operation of the radiant cooling system, the radiant panel surface temperature, indoor air temperature change significantly, the human garment temperature changes slowly, the convection and radiation heat transfer between human body and the environment increase gradually; after 60 minutes operation of the radiant cooling system, all of the above mentioned tend to be steady.
