摘要
以3层固体除湿剂硅胶为除湿层和两层HEPA高效过滤纸为净化层,结合双层玻璃窗户的结构特性,研制出一种新型太阳能除湿净化窗,并利用太阳能对除湿层直接再生。性能试验研究表明:新型太阳能除湿净化窗的有效除湿时间超过26 h,前5 h的平均有效除湿效率达到14.11%;太阳能再生效果好于其它再生工况;PM2.5总平均净化率达到47.50%。新型太阳能除湿净化窗可直接利用太阳能再生,是一种直接利用太阳能满足建筑长时间高效除湿净化需求的装置。
In this paper a new type of window using solar energy to remove moisture,toxins and particles from the air passing through it was designed and researched by experimental. The window had a structure of double-glazing which contains three layers of solid silica gel as desiccant and two layers of high efficiency particle arresting(HEPA)filter paper as purifying layer,the desiccant layers were regenerated by solar energy directly. The performance test results shown that effective dehumidification time of the solar desiccant purification window could last more than 26 h,the average effective dehumidification efficiency could reach up to 14.11% during first 5 h,the average purification rate for PM 2.5 could reach 47.50%,and the solar radiation regeneration was better than other regeneration ways. The solar desiccant purification window could perform a highly efficient air dehumidification and purification in a long-term for building because it could be regenerated by solar energy directly.
