Energy-Saving Wall's Frequence Response to Outdoor Sol-Air Temperature under the Climate of Lhasa Area
摘要
Abstract
The 4th-order harmonic Fourier series to express the outdoor sol-air temperature function is a-dopted as the wall outside boundary conditions, and the theory of wall-body thermal system is used to analyze the effect of different wall orientations and different formation of energy-saving wall bodies in Lhasa area upon time lag and decrement factor. The analytical results indicate that wall orientation, wall body configuration patterns and wall material thermo-physical parameters, etc. Can have the obvious effect upon time lag and decrement factor of which the exterior insulation configuration with sand-lime brick masonry with large storage coefficient is of the maximum decrement factor and longer time lag.关键词
