Nishga Initiative and Missionary Response: Robert Doolan at Quinwoch, B.C.
(SAGE, 1981-07-01)In this historical study of the work of pioneer missionary Robert Doolan, Professor Patterson points out the initiative shown by the Nishga people of the northwest coast of British Columbia and how this interest helped ... -
A Novel Furnace Design Utilizing a Low Temperature Plastic Condensing Heat Exchanger
(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 ... -
Native Missionaries of the North Pacific Coast: Philip McKay and Others
(University of the Pacific, 1986)IN WRITING THE HISTORY of nineteenth century Christian missions the tendency has been to deal primarily with the European and Euro-American or Euro-Canadian missionaries and their exploits—as adventure, devotion, sacrifice, ... -
Effective U-values and Shading Coefficients of Preheat/Supply Air Glazing Systems
(1986-06)Research is documented which makes use of a computer program called VISION, This computer program was developed specifically to provide a detailed analysis of heat transfer occurring in glazing systems. VISION was modified ... -
Simulation And Measurement Of Windows With Metal Films Used In Conjunction With Teflon Inner Glazings
(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 ... -
Simulation and Measurement of Windows with Low Emissivity Coatings Used in Conjunction with Teflon Inner Glazings
(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 ... -
Glazing System U-Value Measurement Using a Guarded Heater Plate Apparatus
(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 ... -
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 ... -
Natural Convection in Sealed Glazing Units: A Review
(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 Study Of Pane Spacing In Glazing Systems
(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
(1989-11)The existing design of glazing system edge-seals creates increased edge-glass heat transfer at the perimeter of sealed glazing units. This thermal short-circuit caused by edge-seal conduction results in added mechanical ... -
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 ... -
Calculating Window Solar Heat Gain
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 1995-07)Window design has been revolutionized-largely by the introduction of low emissivity (low-e) coatings and substitute fill gases. The large number of design options necessitates the use of computer simulation for development ... -
Summary and comparison of methods to calculate solar heat gain
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 1995-08)Methods used to calculate the solar gain of windows (including center-glass, edge-glass, and frame) are examined and compared Particular attention is devoted to the public-domain computer programs VISION3 and WINDOW 4.1. ... -
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 ... -
