Research on Thermal Stability of Configuration of Residential Building Energy-Saving Exterior Wall in Northwestern Areas
摘要
Abstract
With the wall thermal system the paper analyzes the impact of energy-saving exterior wall configuration form on the time lag and decrement factor. Taking the residential buildings in Yinchuan areas for example, the paper calculates the time lag and decrement factor to the disturbance quantity of the outdoor temperature for the walls of different configuration forms with the same heat-transfer coefficient and heat inertia index, the paper also analyzes the difference of stabilizing ability to the disturbance quantity of the outdoor temperature in three kinds of wall thermal insulations. The results show that the wall configuration form has obvious effect on the thermal stability, in which the decrement factor of the outside thermal insulation configuration form is maximum, while the sandwich thermal insulation configuration form has the longest time lag.关键词
