Experimental study of full-size automated venetian blind windows

This study presents an experimental study on full-size automated venetian blind window systems consisting of horizontal pivoted louvers installed and hermetically sealed between two glass panes. The experimental study was carried out using a test cell of 2.43 m high, 1.48 m wide, and 1.92 m deep. Various parameters were measured instantaneously and recorded using a data acquisition system: interior and exterior air temperatures; various surface temperatures; and total and direct solar radiations. A linearized numerical model was used to verify the experimental results.
