Book excerpt: "It doesn't matter if the hoods work, it only matters that we have them and that people assume they work."This callous comment from a laboratory owner who was preparing to build a new laboratory shocked fume hood designer and manufacturer, Chip Albright and convinced him to write this book. Albright's 40 years in the fume hood industry took him into hundreds of laboratories around the world and exposed the fact that the fume hood is the most misunderstood and misused safety device in most laboratories. Until now, understanding the complexity of laboratory ventilation systems was a nearly impossible feat for most. This book takes a step by step approach to explaining the interface between the fume hood, the laboratory ventilation system and the building HVAC. It reveals not only the failings of these systems, but suggests solutions for making them better. Albright's holistic approach to the subject is refreshing and effective. If you own or work in a laboratory, this book is required reading.Finally, a single source that includes:?the history of the fume hood?a detailed explanation of how a fume hood works?why most fume hoods do not perform effectively?why all laboratory users should be concerned?how to ensure that your laboratory fume hood is actually keeping your laboratory safe

Download or read book Mock up and Testing of a Variable Volume Laboratory Fume Hood Exhaust System written by and published by . This book was released on 1980 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A test of an ANL-designed variable volume system prototype used to displace an existing constant volume fume hood ventilation system in a laboratory of the Materials Science Division is described. Performance characteristics such as response, stability, repeatability and hood containment were tested and evaluated, with particular emphasis on containment, to clearly demonstrate that operator safety and the environment are not compromised. Results obtained clearly indicate the feasibility of implementing the prototype concept. The variable volume system enables reducing conditioned ventilation air to the laboratory room by at least 50%, dependent solely upon internal heat loads. Normal hood exhaust of 200 CFM with the face sash in a closed position can be provided by air used to condition building offices and corridors. In all modes of operation, i.e., fume hood face sash closed to fully open, the building differential pressure design criteria from office to corridor to laboratory to fume hood is maintained. Also, hood face velocity can be established to meet minimum requirements at any position of sash opening and test results indicate a hood containment efficiency equal to or better than the presently existing constant volume proportional by-pass system.

Download or read book Energy and Cost Savings for Variable Air Volume VAV Laboratory Fume Hoods in Two University Research Buildings written by and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The volume of lab exhaust for Engineering Building 1 (EB-1) and Partners III, which are research labs located on North Carolina State University's Centennial Campus, is measured and analyzed. There are three main objectives. The first is to determine how the actual system exhaust compares to the total design capacity of the lab HVAC system. Next, the potential additional savings that would result from carefully keeping fume hoods closed when no one is working in the hood. Then, estimate the actual savings that result from using variable air volume (VAV) fume hoods in place of constant volume (CV) hoods. Lab buildings require much more energy for the HVAC system than other academic buildings because of their high minimum airflow set points, once-through air for supply, and high static pressures for the ventilation system. VAV fume hoods can reduce the HVAC energy requirements by reducing the hood exhaust flow to about one-fourth of the full flow when the fume hoods are closed. However, it is total lab exhaust that drives energy use, and the actual reduction in total exhaust cannot be assumed to be equal to a reduction in fume hood exhaust. This is true in EB-1 because minimum airflow set points are 10-12 air changes per hour (ACH), and a general exhaust box maintains this minimum. Thus, when all 70 fume hoods in EB-1 were closed on Friday evening before the Labor Day holiday in 2005 there was a drop of 14,166 CFM in fume hood exhaust. However, total exhaust dropped by only 8,156 CFM, which is 58% as much. Therefore, energy savings made possible by closing the fume hoods would be grossly overestimated if the drop in total lab exhaust had been assumed to be equal to the drop in fume hood exhaust. The total exhaust rate was determined to be almost constant at about 68% of the maximum design airflow for EB-1 during the trended period. The total exhaust was relatively constant over the trended period of about one month because most of the labs were controlled by the minim.

Download or read book Low Flow Fume Hood written by and published by . This book was released on 2002 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A fume hood is provided having an adequate level of safety while reducing the amount of air exhausted from the hood. A displacement flow fume hood works on the principal of a displacement flow which displaces the volume currently present in the hood using a push-pull system. The displacement flow includes a plurality of air supplies which provide fresh air, preferably having laminar flow, to the fume hood. The displacement flow fume hood also includes an air exhaust which pulls air from the work chamber in a minimally turbulent manner. As the displacement flow produces a substantially consistent and minimally turbulent flow in the hood, inconsistent flow patterns associated with contaminant escape from the hood are minimized. The displacement flow fume hood largely reduces the need to exhaust large amounts of air from the hood. It has been shown that exhaust air flow reductions of up to 70% are possible without a decrease in the hood's containment performance. The fume hood also includes a number of structural adaptations which facilitate consistent and minimally turbulent flow within a fume hood.
