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 ...
Calculating Center-Glass Performance Indices of Glazing Systems with Shading Devices
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 2008)
Building energy consumption and loads are strongly influ-enced by solar gain and heat transfer through the centre-glass area of windows. Methods have been devised to calculate the corresponding energy performance indices ...
Solar Gain through Windows with Shading Devices: Simulation Versus Measurement
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 2009)
Shading devices offer a cost saving strategy in dynamically controlling solar gain through windows. As such, there is an ongoing effort to accurately quantify the thermal performance of shading devices. In the present ...
Thermal Resistance of a Window with an Enclosed Venetian Blind: A Simplified Model
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 2008)
Solar gain has a strong influence on building energy consumption and peak cooling load. Venetian blinds are routinely used to control solar gain. Software based on 1-D models is available to accurately predict the thermal ...
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 ...
Improving Load Calculations for Fenestration with Shading Devices
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 2009-10)
Activities and findings arising from ASHRAE Research Project 1311-RP are summarized. This project included three main goals, (a) development of models for pleated drapes, venetian blinds, roller blinds and insect screens, ...
Methods for Calculating the Effective Solar-Optical Properties of a Venetian Blind Layer
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 2005)
Window solar gain can strongly influence building energy consumption, peak loads, and comfort. Shading devices are routinely used to control solar gain. The use of venetian blinds is particularly common. There is a strong ...
Determining Off-Normal Solar Optical Properties of Drapery Fabrics
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 2009)
The determination of off-normal solar optical properties of drapery fabrics is particularly useful in modelling the effective solar optical properties of pleated drapery. Special sample holders were designed and fabricated ...
Sensitivity of the Solar Heat Gain Coefficient of Complex Fenestration Systems to the Indoor Convection Coefficient
(International Building Performance Simulation Association, 2016)
Accurate estimation of the solar gain of a fenestration system is important in analyzing the energy performance of buildings. Recently, models were developed for complex fenestration systems – glazing systems with attachments ...
Forced Convection From a Pair Of Spheres: A Three-Temperature Problem
(2015-05)
Interaction of spherical particles in a fluid flow is important in combustion, chemical processes and air pollution. In this study, a recently developed technique for characterizing multi-temperature convective heat transfer ...
