Calculating the Solar Heat Gain of Window Frames
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 1999)It is not practical to measure the solar heat gain of a window frame. It is more practical to do so by calculation. Typically, the frame solar heat gain is a small component of the total or is small in absolute terms so ... -
Overview of a Project to Determine the Surface Temperatures of Insulated Glazing Units: Thermographic Measurement and Two-Dimensional Simulation
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 1996)A collaborative research project was undertaken to generate surface temperature profiles for the indoor side of seven different double and triple-glazed insulated glazing units exposed to the ASHRAE winter design condition. ... -
Solar Absorption by Each Element in a Glazing/Shading Layer Array
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 2006)Window solar gain can strongly influence building energy consumption and peak cooling load. Shading devices such as venetian blinds, roller blinds, and drapes are routinely used to control solar gain. There is a strong ... -
A study of insulated glazing unit surface temperature profiles using two-dimensional computer simulation
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 1996)This paper describes one part of a collaborative research project, including both measurement and simulation studies, aimed at determining the surface temperature of a set of insulated glazing units (IGUs). In this study ... -
Thermal resistance measurement of glazing system edge-seals and seal materials using a guarded heater plate apparatus
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 1989)In cold climates the increased edge-glass heat transfer at the perimeter of a sealed glazing unit creates a special problem. This is where condensed water and frost most readily occur. One mechanism contributing to edge-glass ... -
A two-dimensional numerical model for glazing system thermal analysis
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 1995-08)A simple two-dimensional (2-D) numerical control volume formulation is presented that can be used to model heat transfer through a vertical insulated glazing unit. This model accounts for natural convection of the fill gas ... -
A two-dimensional numerical model for natural convection in a vertical, rectangular window cavity
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 1994-12-31)It is common for sealed glazing units to exhibit condensation problems when operated in cold climates. Condensation often forms along the perimeter of the exposed surface of the indoor glazing because of the thermal short ...
