外围护结构对建筑空调能耗的影响研究

Study on the Influence of Peripheral Protection Structure on the Energy Consumption of Building Air Conditioning

建筑节能设计作为一种新的设计理念,已在建筑界广泛应用。建筑节能的检测和评价要求能够快速、准确、全面地反映建筑的能耗状况,并能够科学、公正地作出评价。DOE-2是学界公认的建筑能耗分析结果最为准确的软件之一,通过该软件建立分析模型,表明当外墙传热系数降低50%时,建筑物的能耗将降低15%左右,降低墙体的太阳辐射吸收系数将有利于节约建筑空调能耗。

As a new design concept,building energy saving design has been widely used in the construction industry.The detection and evaluation of building energy efficiency requires that it can reflect the situation of building energy consumption quickly,accurately and comprehensively,and make a scientific and fair evaluation.DOE-2 is recognized as one of the most accurate software for building energy consumption analysis results.The analysis model established by this software shows that when the heat transfer coefficient of the external wall is reduced by 50%,the energy consumption of the building will be reduced by about 15%.Reducing the solar radiation absorption coefficient of the wall will be conducive to the energy saving of building air conditioning.
