建筑玻璃贴膜节能性能研究

Energy-saving Performance of Building Film

对目前市场上常用的建筑贴膜进行隔热率、节能率研究,现场采用两间面积及窗户面积相同、朝向相同的房间,采用安装冷热量仪实时监测及自动采集方式,辅以光照及温度现场检测。得出窗户在夏季和冬季贴膜后,对室内室温的影响、对室内光照度影响,以及对空调运行参数及耗能量的影响;测试开空调后的温升及温降情况,并观测冷热量仪的实际耗能量读数,得出贴膜后的节能率。通过实验得出隔热膜对应节能参数,对实施建筑隔热膜节能改造有一定的指导意义。

High heat rejection and energy saving efficiency of the architectural film commonly used in the current market are investigated.Two rooms with same dimension,equal window area,and identical orientation are adopted on-site.Real-time monitoring and automatic collection are conducted by means of the heat calorimeter,supplemented by on-site inspection of illumination and temperature.The influence of building film exerted upon room temperature,indoor illuminance,with operating parameters and energy consumption of air conditioning are tested,in summer and winter respectively.The up and down profile of temperature,as well as actual consumption of the calorimeter is observed during air conditioning,so that the energy efficiency of the film is obtained.The corresponding energy-saving parameters of the insulation film are obtained through experiments,which has certain guiding significance for the implementation of the energy-saving retrofitting of the building insulation film.
