【摘要】 夏热冬冷地区博物馆建筑的能耗居高不下,采取适宜的被动节能技术是其低碳发展的关键。本文对夏热冬冷地区常见的被动节能技术进行概述,并以白石篆刻艺术博物馆为例,采用EnergyPlus能耗模拟软件探究各项节能技术对其建筑能耗的影响。结果表明:电扇空调联动控制技术对空调冷负荷的节能效果最佳,节能率为15.75%,围护结构性能提升对空调热负荷的节能效果最佳,节能率为9.53%,综合节能技术兼顾了各项节能技术的特点,全年空调总负荷的节能率达到12.80%。在考虑照明能耗后,可调节内遮阳大幅增加了建筑照明能耗,节能率为一8.21%。而对于建筑总能耗而言,电扇空调联动控制技术节能效果最佳,为3.42%,可调节内遮阳节能效果最差,为-0.56%,综合节能技术节能率也仅达到4.60%。因此,夏热冬冷地区的博物馆此类大空间公共建筑仅依靠被动节能技术难以达到理想的节能效果,需结合其他节能措施进一步降低建筑能耗。更多还原

【Abstract】 The building energy consumption of museums in hot summer and cold winter areas is high,and adopting appropriate passive energy saving technology is the key to its low-carbon development.This paper summarizes the common passive energy saving technologies in hot summer and cold winter areas,and takes The Baishi Engraving Art Museum as an example to explore the impact of energy saving technologies on its building energy consumption by using EnergyPlus energy simulation software.The results show that the linkage control technology of electric fan air conditioning has the best energy saving effect on the cooling load of air conditioning,and the energy saving rate is15.75%.The improvement of enclosure structure has the best energy saving effect on the heat load of air conditioning,and the energy saving rate is 9.53%.The comprehensive energy saving technology takes into account the characteristics of various energy saving technologies,and the energy saving rate of the total air conditioning load reaches 12.80% in the whole year.After considering the lighting energy consumption,the adjustable internal shading significantly increases the building lighting energy consumption,and the energy saving rate is-8.21%.For the total energy consumption of buildings,the linkage control technology of electric fans and air conditioners has the best energy saving effect of 3.42%,the worst energy saving effect of adjustable internal sunshade is-0.56%,and the energy saving rate of comprehensive energy saving technology only reaches 4.60%.Therefore,such large-space public buildings as museums in hot summer and cold winter areas cannot achieve ideal energy saving effect only by relying on passive energy saving technology,and other energy saving measures should be taken to further reduce building energy consumption.更多还原
