Impact analysis of heating methods on room temperature stability

This paper established building inner wall heat balance equation and indoor air heat balance equation for some typical rooms in Harbin using floor radiant heating and radiator convection heating. Reaction coefficient method was chosen to calculate the unsteady state heat conduction of the wall, Gauss Jordan elimination method was adopted to solve equation set. The calculation programming was based on the theories above. This study compared the indoor air temperature in different typical rooms under the different heating time of intermittent heating. This study drew a series of curves depicted the indoor air fluctuation. The result showed that the room thermal stability of radiant heating method was better than that of convection heating method.
