A study on radiative and convective heat exchange in a room with floor heating

Several features of heat transfer on enclosing surfaces is discussed including temperature distributions in a room heated by a floor heater. Experiments and numerical analysis on radiative and convective heat transfer were carried out against several partial floor heating. Partial floor heating produces different types of temperature distribution between the heated and non-heated places, which is an remarkable characteristics found out in this study. In the heated places, the temperature distribution is almost the same as that of typical floor heating. However, in the nonheated places, air temperature differs by 2 °C (3.6 °F difference) between a point near the floor surface and a point well above that. Heating efficiency of partial heating slightly depends on the set place as well as its area. Moreover, convective heat exchange constitutes approximately half of the total heat exchange.
