Abstract

We analyzed three forms of heating system which is under the similar meteorological condition by testing the temperature distribution of the radiant surface, the distribution of the indoor air temperature in the horizontal and vertical directions, the interior surface temperature of the non-heated surface of the room, and the indoor and outdoor temperature and humidity. The PMV and PPD indexes were used to evaluate the thermal comfort of laboratory in winter. The results show that with other condition unchanged, the human body stands and relaxes and dressed in winter indoor clothes (clothing thermal resistance for 1.2–1.5 clo), the new floor heating room comfortable air temperature would be 17–21 °C, and the optimal water supply temperature is recommended to be 40–43 °C.
