Experimental determination of the solar heat gain coefficient of inside blinds
Ingo Haug, Andreas Beck, Jochen Fricke
Two experimental setups are used to determine the solar heat gain coefficient (g value) of a system consisting of double glazing and inside blinds. The first setup determines the radiative fraction of the g value, while the second one measures the convective fraction. The measured results from both setups are discussed and compared to model calculations. The measured g value differs by about 18% from the calculated g value. The g value of the double glazing with inside blinds is 8% smaller than the g value of the double glazing without blinds. Further investigations are under way to clarify the observed deviations between experiment and model.
