Glazing System U-Value Measurement Using a Guarded Heater Plate Apparatus
Wright, John L.; Sullivan, Harry F. (American Society of Heating, Refrigerating and Air-Conditioning Engineers, 1988)Precise heat transfer measurements have been carried out during the last 20 years using a guarded heater plate apparatus. This apparatus has been adapted and used over the last several years to perform U-value measurements ... -
Natural Convection in Sealed Glazing Units: A Review
Wright, John L.; Sullivan, Harry F. (American Society of Heating, Refrigerating and Air-Conditioning Engineers, 1989)In cold climates the augmented edge-glass heat transfer at the bottom of a glazing system creates a special problem. This is where condensed water and/or frost most readily occur. Two mechanisms determining the rate of ... -
A Novel Furnace Design Utilizing a Low Temperature Plastic Condensing Heat Exchanger
Wright, John L.; Sullivan, Harry F. (1982-03)The initial phase of a research and development program for the Consumers' Gas Co. and the Federal Department of Energy, Mines and Resources to design a condensing heat exchanger/gas fired residential air furnace has been ... -
Overview of a Project to Determine the Surface Temperatures of Insulated Glazing Units: Thermographic Measurement and Two-Dimensional Simulation
Wright, John L.; Sullivan, Harry F.; Fraser, Roydon A. (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. ... -
Simulation and Measurement of Windows with Low Emissivity Coatings Used in Conjunction with Teflon Inner Glazings
Wright, John L.; Sullivan, Harry F. (1987-09)Theoretical work has illustrated that highly infrared, transparent plastic films are well suited for use as intermediate glazings when used in conjunction with a low emissivity coating. Prototype glazing systems that ... -
Simulation And Measurement Of Windows With Metal Films Used In Conjunction With Teflon Inner Glazings
Wright, John L.; Sullivan, Harry F. (1987-09)Previous work has shown that highly infrared transparent plastic films are well suited for use as inner glazings when used in conjunction with a low emissivity coating. Thermal resistance measurements of a set of glazing ... -
A study of insulated glazing unit surface temperature profiles using two-dimensional computer simulation
Wright, John L.; Sullivan, Harry F.; De Abreu, Pedro Felipe; Fraser, Roydon A. (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 ... -
A Study Of Pane Spacing In Glazing Systems
Wright, John L.; Baker, J. A.; Sullivan, Harry F. (Solar Energy Society of Canada, 1989-06)The selection of optimum pane spacing for glazing systems has been a topic of ongoing debate in the window manufacturing industry. Arguments are often based on speculation, intuition and results from tests not specifically ... -
Thermal resistance measurement of glazing system edge-seals and seal materials using a guarded heater plate apparatus
Wright, John L.; Sullivan, Harry F. (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
Wright, John L.; Sullivan, Harry F. (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
Wright, John L.; Sullivan, Harry F. (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 ...
