摘　　要：采用羟丙基甲基纤维素(HPMC)、氯化钠、纯净水研制了绿色纤维素醚类热致调光材料,测试了不同配比下的热致转变温度、可见光透射比及太阳光直射透射比。通过能耗模拟分析,研究了不同配比热致调光中空玻璃窗的节能效果。结果表明:羟丙基甲基纤维素(HPMC)、氯化钠、纯净水质量配比在2:15:100时,可以较好地满足实际建筑热致转换需求,以此配比研制的热致调光中空玻璃窗运用于夏热冬冷地区,其节能效果比Low-E中空玻璃窗高约3%,比普通中空玻璃窗高约8%。此类热致调光材料在节能建筑和绿色建筑中具有广阔的应用前景。Hydroxypropylmethyl cellulose （HPMC）, Sodium Chloride and pure water were adopted to develop green cellulose ethers thermotropic materials. And thermally induced switching temperature, visible and solar direct transmittance were measured under different mixing proportion. For energy consumption, DeST-h was used to study the energy efficient effect of thermotropic double-glazing windows with different mixing proportion. It was shown that the optimum mixing proportion of hydroxypropylmethyl cellulose（HPMC）, Sodium Chloride and pure water was 2：15：100 by mass. And thermotropic double-glazing window can reduce energy consumption by 3% and 8%, respectively, when compared with Low-E double-glazed window and common double-glazed window in hot summer and cold winter zone.
