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 ...
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, ...
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 Detailed Model to Determine the Effective Solar Optical Properties of Draperies
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 2009)
Drapes have the potential to reduce peak cooling load and annual energy consumption because they can be used to control solar gain. Thus, the need to model a drapes in a glazing system analysis is important. A detailed ...
Heat Transfer Analysis of a Between-Panes Venetian Blind Using Effective Longwave Radiative Properties
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 2004)
Center-glass thermal analysis programs based on one-dimensional models have proved to be exceptionally useful. Recently efforts have been made to extend the analysis to include venetian blinds. It is convenient to model ...
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 ...
A Comparison of Calculated and Measured Indoor-Side Window Temperature Profiles
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 2003)
Computer-generated surface temperature profiles are presented for the indoor side, vertical centerline of two windows and a calibration transfer standard (CTS). These specific configurations were chosen because they match ...
Determining Off-Normal Solar Optical Properties of Roller Blinds
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 2009)
Solar gain through fenestration constitutes a significant portion of peak cooling load and annual energy consumption in buildings. As such, any reduction in solar gain translates into savings associated with the cost of ...
