摘要
为探究金属有机框架(Metal-organic Framework:MOF)调湿内饰面材料GF-10对普通办公建筑温湿度及能耗的影响,在人工环境舱测试了材料效果,并用DesignBuilder模拟了2种气象下2种材料在5个代表城市的20组工况。研究发现,广州高温高湿气候下通风1次/h时,1 mm厚GF-10可显著影响辐射供冷房间内温湿度,降低312 g/m3湿负荷。模拟结果显示,20 mm厚GF-10可起到湿缓冲作用,且湿度调节具有季节性,最热月效果更显著。其高低湿总缓解指数按哈尔滨(45 h·%)、上海(38 h·%)、北京(36 h·%)、广州(23 h·%)、昆明(11 h·%)排序,且未来气象下,湿缓冲程度将更强。在能耗上,20 mm厚GF-10材料可降低除湿和加湿负荷,在上海和广州两地可降低3.35 kW·h/m^(2)、2.72 kW·h/m^(2)总负荷和超20%的除湿加湿负荷。GF-10材料在上海、广州兼具节能和湿缓冲效果。
To investigate the influence of Metal-organic Framework(MOF)humidity-controlling interior materials GF-10 on the temperature and humidity regulation and energy consumption of general office buildings,this paper tested the material in an artificial environment chamber and 20 working conditions for two different materials,in five representative cities and under two climates were simulated by the DesignBuilder software.The study finds that GF-10 of 1 mm thickness can significantly affect the temperature in the radiant cooling room and reduce the humidity load by 312 g/m^(2)under the high temperature and humidity climate in Guangzhou by ventilating once per hour.The simulation results show that GF-10 of 20 mm thickness can work on the moisture buffering and adjust the humidity seasonally.And the regulation of humidity is more evident in the hottest month.The total mitigation of accumulating high and low humidity index(AHHI/ALHI)is sorted as Harbin(45 h:%)>Shanghai(38 h·%)>Beijing(36 h.%)>Guangzhou(23 h·%)>Kunming(11 h·%).The moisture buffering will be more obvious in future climates.In terms of energy consumption,GF-10 of 20 mm thickness can reduce dehumidification and humidification load.Specifically,it can reduce the total load of 3.35 kW.h/m^(2)and 2.72 kW.h/m^(2) in Shanghai and Guangzhou respectively,and decrease dehumidification and humidification load by more than 20%.GF-10 can achieve better effects on both energy saving and moisture buffering in Shanghai and Guangzhou.
