本文报道了Ag-SnO_2透明绝热涂层的研究结果。Ag-SnO_2薄膜具有良好的光谱选择特性,可见光波长范围内的平均透过率为55.4％,透过率峰值等于75％,峰值波位为0.55μm。薄膜具有很好的热反射特性,红外反射率大于90％。 在玻璃上沉积Ag-SnO_2薄膜,可大大延缓传热,计算得到窗口热流量与温度关系为 a.对于玻璃(G)和带膜玻璃(G/F)窗口, Q=0.1308(T_(tn)-T_(out)) b.对于双层玻璃(2G)和夹膜双层玻璃(G/F+G)窗口, Q=0.083(T_(tn)-T_(out)) 从综合技术经济指标考虑,单层玻璃加透反膜的组合窗口(G/F)最好,其绝热效率比单层玻璃(G)提高52％,比双层玻璃(2G)提高11％。
This paper reports the results of Ag-SnO 2 transparent thermal insulation coatings. The Ag-SnO 2 thin film has good spectral selectivity with an average transmittance of 55.4% in the wavelength range of visible light, a peak transmittance of 75% and a peak wavelength of 0.55 μm. The film has good heat reflection characteristics, infrared reflectance greater than 90%. The deposition of Ag-SnO 2 thin film on glass can delay the heat transfer greatly. The calculated heat flux of the window is related to the temperature a. For the glass (G) and glass with a glass window (G / F), Q = 0.1308 (Out)) b. Q = 0.083 (T_ (tn) -T_ (out)) for double glass (2G) and double glazing (G / F + G) windows Considering from the technical and economic indicators (G / F), the thermal insulation efficiency is 52% higher than that of single-layer glass (G) and 11% higher than that of double-layer glass (2G).
