The thermal performance of the glass window with a curved venetian blind installed in the shortwave part of radiation is investigated.
The SHGC, ShW SHGC and LoW SHGC are chosen as the key indices for the system thermal performance.
Installing blind to the plain glass window causes the decrease in heat gain.
The amount of reduction in heat gain is mainly dependent on the glass optical properties, slat optical properties, slat angle and solar profile angle.
The heat gain in the shortwave part of radiation (ShW SHGC) through the glass window with blind is analyzed.
It is also found that the glass window with blind of a lower value of slat reflectance, has a smaller value of ShW SHGC.
The slat distance also affects the ShW SHGC. The glass window with blind of a lower value of slat distance gives a lower
value of ShW SHGC.
The effect of the slat curvature on the ShW SHGC is small when compared to the effect of other parameters.
