Study on the Design and Construction of New Active Dynamic Composite Envelope Structure and Performance Test Analysis

建筑围护结构作为室内外的环境缓冲层,是影响建筑室内热舒适度和建筑能耗的重要因素和关键部件。本文通过整合保温隔热技术与光伏发电技术,设计并尝试搭建了1种新型有源动态复合围护结构,对该围护结构在冬季工况下的热工性能进行了测试研究,测试结果表明:该围护结构在阴天和晴天工况下内壁面温度较相应不通热水上升0.7℃和3℃左右,阴天条件下建筑散热可减少50%,晴天条件下建筑得热能增加3.5~6.7倍,旨在探索1种整合光伏发电系统和改善玻璃幕墙热工性能的办公等公共建筑围护结构,促进实现大面积使用幕墙结构建筑的近零能耗目标。

Building envelope,as an environmental buffer layer between indoor and outdoor,is an essential factor and key component affecting the indoor thermal comfort and energy consumption of buildings.This paper designed and constructed a new type of active dynamic composite envelop enclosure structure based on thermal insulation and photovoltaic power generation technologies,and tested and analyzed its thermal performance under winter conditions.The test results show that the temperature of the inner wall surface increases by 0.7℃ and 3℃ under cloudy and sunny conditions respectively,and the heat dissipation of the building is reduced by 50%under cloudy conditions,and the heat gain of the building is increased by 3.5~6.7 times under sunny conditions.It aims to develop an envelope structure for public buildings integrating the photovoltaic power generation system and improved thermal performance of glass curtain walls,so as to achieve the goal of near-zero energy consumption for buildings with a large curtain wall structure.
