Book excerpt: This study tests the performance of a variable airflow small-diameter duct heating, ventilation, and air conditioning (HVAC) system in a new construction unoccupied low-load test house in Pittsburgh, Pennsylvania. The duct system was installed entirely in conditioned space and was operated from the winter through summer seasons. Measurements were collected on the in-room temperatures and energy consumed by the air handler and heat pump unit. Operation modes with three different volumes of airflow were compared to determine the ideal airflow scenario that maximizes room-to-room thermal uniformity while minimizing fan energy consumption. Black felt infrared imagery was used as a measure of diffuser throw and in-room air mixing. Measured results indicate the small-diameter, high velocity airflow system can provide comfort under some conditions. Solar heat gains resulted in southern rooms drifting beyond acceptable temperature limits. Insufficient airflow to some bedrooms also resulted in periods of potential discomfort. Homebuilders or HVAC contractors can use these results to assess whether this space conditioning strategy is an attractive alternative to a traditional duct system. The team performed a cost analysis of two duct system configurations: (1) a conventional diameter and velocity duct system, and (2) the small-diameter duct system. This work applies to both new and retrofit homes that have achieved a low heating and cooling density either by energy conservation or by operation in a mild climate with few heating or cooling degree days. Guidance is provided on cost trade-offs between the conventional duct system and the small-diameter duct system.
Book Synopsis Dust Control Handbook for Industrial Minerals Mining and Processing by : Andrew B. Andrew B. Cecala
Download or read book Dust Control Handbook for Industrial Minerals Mining and Processing written by Andrew B. Andrew B. Cecala and published by CreateSpace. This book was released on 2015-05-09 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Throughout the mining and processing of minerals, the mined ore undergoes a number of crushing, grinding, cleaning, drying, and product sizing operations as it is processed into a marketable commodity. These operations are highly mechanized, and both individually and collectively these processes can generate large amounts of dust. If control technologies are inadequate, hazardous levels of respirable dust may be liberated into the work environment, potentially exposing workers. Accordingly, federal regulations are in place to limit the respirable dust exposure of mine workers. Engineering controls are implemented in mining operations in an effort to reduce dust generation and limit worker exposure.

Download or read book America's Role in Nation-Building written by James Dobbins and published by Rand Corporation. This book was released on 2003-08-01 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: The post-World War II occupations of Germany and Japan set standards for postconflict nation-building that have not since been matched. Only in recent years has the United States has felt the need to participate in similar transformations, but it is now facing one of the most challenging prospects since the 1940s: Iraq. The authors review seven case studies--Germany, Japan, Somalia, Haiti, Bosnia, Kosovo, and Afghanistan--and seek lessons about what worked well and what did not. Then, they examine the Iraq situation in light of these lessons. Success in Iraq will require an extensive commitment of financial, military, and political resources for a long time. The United States cannot afford to contemplate early exit strategies and cannot afford to leave the job half completed.
Book Synopsis Net Zero Energy Buildings by : Linda Reeder
Download or read book Net Zero Energy Buildings written by Linda Reeder and published by Routledge. This book was released on 2016-03-31 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents 18 in-depth case studies of net zero energy buildings—low-energy building that generate as much energy as they consume over the course of a year—for a range of project types, sizes, and U.S. climate zones. Each case study describes the owner’s goals, the design and construction process, design strategies, measurement and verification activities and results, and project costs. With a year or more of post-occupancy performance data and other project information, as well as lessons learned by project owners and developers, architects, engineers, energy modelers, constructors, and operators, each case study answers the questions: What were the challenges to achieving net zero energy performance, and how were these challenges overcome? How would stakeholders address these issues on future projects? Are the occupants satisfied with the building? Do they find it comfortable? Is it easy to operate? How can other projects benefit from the lessons learned on each project? What would the owners, designers, and constructors do differently knowing what they know now? A final chapter aggregates processes to engage in and pitfalls to avoid when approaching the challenges peculiar to designing, constructing, and owning a net zero energy building. By providing a wealth of comparable information, this book which will flatten the learning curve for designing, constructing, and owning this emerging building type and improve the effectiveness of architectural design and construction.
