Experimental investigation and dynamic modeling of a triple-glazed exhaust air window with built-in venetian blinds in the cooling season

Analysing the existing dynamic insulation technologies focusing on buildings’ renovation – A review

“…Other similar systems, yet more complex, involve triple-glazed windows dealing both with the heating and the cooling period, aiming at keeping high the internal pane's temperature on the heating mode, and cooling the external pane on the cooling mode, via the ventilation strategy followed [38]. A venetian blind addition could further enhance the systems' performance [39].…”

“…From the thermal diode assemblies described in the relevant paragraph, only the one operating with gravity for possible roof application might be sustainable for an existing building [25], as it requires no further mechanism or automation for its proper operation. Double skin facades [27][28], is already a common renovating technique, whereas the exhaust air windows [37]- [39], can be easily applied even to existing buildings, necessarily accompanied by the proper HVAC systems to assure their proper operation.…”

Study on the Sensitivity of Zonal Model for Evaluating the Thermal Performance of Ventilated Window

“…The detailed information about the development of the zonal model for evaluating the thermal performance of the VEW can be found in our previous studies [4]. It should be noticed that the subsection number in vertical direction may directly affect the calculation accuracy as well as the computation time of the zonal model.…”

“…The experiment setup, test sample, measurement facilities, and measured boundary conditions can be found in Ref. [4]. The comparison of the numerical modeling and experiment measurement is presented in Fig.…”

“…In addition, there exists a heat recovery window system, which can act as a heat exchange to recover the heat or cold of the exhaust-air to mitigate the heating or cooling load of the window. Such a window system can be called as the ventilated exhaust-air window (VEW) [4][5][6]. The exhaust-air can flow through the gap between the glass panes, and then the conduction heat gain in summer or heat loss in winter would be removed or reduced by the flowing air.…”
