| Abstract: | In this paper, in a simplified physical model based on a reasonable, gas-fired radiant heating on the temperature distribution in space has been simulated, and the influences of different surface emissivity of building enclosure to indoor temperature and energy consumption are pointed. The result shows： reducing surface emissivity of building enclosure can enhance gas-fired radiant heating technology. |
