黄河淤泥多孔砖在居住建筑节能设计中的应用

Application of Yellow River Silt Cellular Brick in Energy-efficiency Design of Residential Building

以《河南省居住建筑节能设计标准》DBJ41/062-2005为依据,分别对黄河淤泥多孔砖和其它种类的墙体材料组成的居住建筑外围护墙体节能保温子系统进行对比分析,从节能保温性能评价的参数:围护结构热阻R和传热系数K两项指标和能耗率及经济指标进行论证。证明了在居住建筑节能保温设计中黄河淤泥多孔砖的技术指标优于市场中现有的其它同类墙体材料,较大幅度提高外围护墙体的节能保温效率、降低成本并减少建筑垃圾的产生;同时也表明围护墙体主材自身的热工性能直接决定着外围护墙体子系统整体的节能指标及投资。

According to the existing Standards of Energy-saving Design for Residential Buildings in He＇ nan Province DBJ41/062-2005, this paper respectively analyzes energy-efficiency insulation subsystem of residential building external wall composed of the Yellow River silt cellular as a new alternative to traditional clay brick by contrast with other types of new wall materials in the energy-efficiency insulation design to conduct feasibility studies from the performance parameters evaluation such as retaining structure thermal resistance R, heat transfer coefficient K indicators, energy consumption rates and economic indicators. It is proved that the Yellow River silt cellular technical indicators are better than other similar existing wall materials in the market in the residential building energy-efficiency insulation design, a more substantial increase for energy-efficiency insulation efficiency of extemal wall is received, it can reduce costs and the production of construction refuse, at the same time the thermal performance of retaining wall itself directly determine the overall energy saving and investment targets for the external wall subsystems.
