ABSTRACT
In this study, cold water panels were laid in the walls of a small pension, and cold-water tubes were installed inside the cold-water panels to examine the cooling performance with radiant heat transfer by the absorption of radiant thermal energy by the cold water leading to the drop of the temperature of the air existing in the internal space of the small pension. The size of the small pension is 2000 mm wide, 1500 mm long, and 1700 mm high. The cooling area of the small pension experimental apparatus is 3 m2, and cold-water panels were laid inside the walls of the small pension. As a result of this study as such, unlike the forced convective heat transfer cooling in which the air existing in the interior space of a small pension is forced to circulate by an air conditioner or an electric fan, the radiant heat transfer cooling by the cold water panels laid in the walls of the small pension in this study implemented comfortable radiant heat transfer cooling, which is also well-being beneficial to health have been realized by implementing the radiant heat transfer cooling without any movement or circulation of the air.
