Description

Air-flow windows, developed in Scandinavia, are being considered for application in arctic and sub-arctic environments. Air-flow windows consist of a double or triple-glazed outer sash and a single glazed inner sash. Room air is returned to the building heating, ventilating and air-conditioning system through the window every cavity existing between the inner and outer sashes, thus warming the inner pane of glass. Air-flow windows have the potential of improving room comfort and reducint building heat losses, particularly if the outdoor air requirement is greater than or at least can be matched to the air extracted through the windows. A sample air-flow window was tested in a guarded hot box at various air flow rates at cold side temperatures ranging from -50(degrees)F to +10(degrees)F. Based on the test results, U-values were calculated for winter night time conditions. The economics of this window system are discussed. The energy balance of an air-flow window is established.
