Led by Ken Yeager, with more than 30 years' experience in the laboratory casework and
fume hood industry, Sydney Science brings extensive knowledge and perception to the education, healthcare and industrial markets.
It also highlights the difference in ducted supply air that results from the combination of chilled beams, high performance
fume hoods, and displacement systems.
Method of testing performance of laboratory
fume hoods. Atlanta: ASHRAE.
Figure 1 shows an "energy driver" mapping of several different labs, making it easy to see what percentage of time each lab is driven by thermal,
fume hood or dilution requirements--as well as the amount of time the lab is running at design minimum flows.
Fume hood features a double wall construction with an angled frame opening with either double vertical side sashes or horizontal sliding glass doors.
As an alternative to ducted
fume hoods, some laboratories use a ductless or advanced filtering
fume hood with a molecular carbon filter.
* Moveable
fume hoods: These are used in place of fixed models.
Typically, lab users tend to prefer
fume hoods without exploring or considering a myriad of other available options.
The 50,000-sf New Technology and Learning Center (NTLC) for Bristol Community College (BCC), Fall River, Mass., brings together disparate programs--chemistry, biology, medical and dental education--holding energy-dense uses, including 18
fume hoods, high plug loads and specific ventilation and lighting requirements.
Patriot ductless
fume hoods feature the advanced technology of the Independence
fume hood and the cost-effective features of the AC4000 folding and sliding-sash ductless
fume hoods.
* Balancing energy use with the need for 67
fume hoods to educate future engineers and scientists; and
