The experiment is set up to measure the surface temperature of a venetian blind installed behind the glass window.
The glass window is facing west.
The glass window is grey glass of 5 mm thickness.
The size of the glass window is 630 1430 mm.
The glass window is installed in the wooden frame with the lower edge is located about 500 mm above the floor.
The aluminum venetian blind is installed at a distance of 35 mm behind the glass window.
The pyranometer (Kipps&Zonen, model CM6B) is placed in front of the glass window at the height about 1450 mm from the floor to measure the incident solar radiation.
The outside temperature, inside temperature and the wind velocity are measured to use as the input for calculating the surface temperature from the developed mathematical model.
The testing room is not air conditioned. The thermoflow thermometer model C-700C, which is an infrared radiometer,
is used to measure the surface temperature of the venetian blind by pointing at the blind from a distance about 70 cm.
The measurement is performed in the afternoon when there is direct solar radiation incidence on the glass window.
The measurement is performed on two slat angles, 0 and +45.
The venetian blinds used in this experiment are blinds having green color and silver color.
The green blind is chosen to represent the blind of low shortwave reflectance.
The silver blind is chosen to represent the blind of high shortwave reflectance.
The properties of the venetian blinds used in this experiment, which are obtained from the measurement by using the spectrophotometer,are shown in Table 2.
The optical properties of the grey glass are given in Table 3.
