Vertical Sash Fume Hood with Bypass Area Open and Closed.
10. If there is no restriction on the bypass, leave BYPASS OPEN at the default
(100%). If the bypass area has an airflow restrictor covering the open area,
such as a perforated grille or louvers, estimate the open percentage of the
bypass area. Set BYPASS OPEN to the appropriate value.
11. Repeat steps 8 through 10 for vertical sash 2. Enter the values into TOP
FRAME B, BYPASS HGHTB, and BYPASS OPENB.
12. Measure the height of vertical sash 1 in inches (cm). Set VSASH HGHT1 to
this value.
13. Measure the height of the vertical sash 2 in inches (cm). Set VSASH
HGHT2 to this value.
14. Measure the fixed area of the fume hood in square feet (square meters).
Any fume hood leakage must be accounted for in this measurement. Set
FIXED AREA to this value.
NOTE: The fixed area of the fume hood is an area that remains open
regardless of sash position or movement. For example, most fume hoods
have an intake gap under the lower airfoil and above the cabinet of the fume
hood (typically a 1 inch gap). Also include 1% of the maximum open face
area in this calculation for other open areas, such as the space between the
sash and the track, and leakage.
15. If the fume hood has a fixed panel in the sash opening of Segment A, locate
the position of the panel by measuring from the bottom of the sash opening
to the bottom of the fixed panel and enter the value into FPANEL POS A.
Measure the height of the fixed panel and enter the value into FPANEL HGT
A. Repeat step 15 for Segment B.
