EXPERIMENTAL-STUDY OF THERMAL PERFORMANCE OF AUTOMATED VENETIAN BLINDWINDOW SYSTEMS

This article presents an operational and thermal performance study on automated venetian blind window systems. They are systems with pivoted louvers installed horizontally, sealed hermetically between two glass panes and controlled automatically following the thermal needs. The e xperimental studies were carried out in two identical test cells (2.43 m high, 1.48 m wide, and 1.92 m deep) used as variable temperature ca lorimeters. One was equipped with an automated window system and the o ther double glass window without louvers. Various parameters were meas ured and recorded: louver angle, inside and outside air temperatures, cloud cover. The operational and thermal performances of the automated louver system have been demonstrated and compared with that of the or dinary system.
