Abstract

An experimental study was made to determine correlations that allow the calculation of heat transferred by convection through the window. Three configurations were studied: a hot plate; a cold plate and a window with a single-step frame placed on the wall of a room. We obtained a correlation that can be used to calculate the convection heat transfer through the window. The new correlation in the hot plate configuration differs by 14.5% from the ASHRAE correlation for laminar free convection on a vertical surface, is 27.5% from the cold plate and is 12% from the single step-frame. © 2003 Elsevier Ltd.All rights reserved.
