apart in the bulk-storage area (Figure 1b). The warehouse
was modeled with (Figure 1c) and without racks, with
the racks oriented to provide the most benefi cial airfl ow
performance across most aisles. Simulation results are
reported mostly at the whole-warehouse-breathing-zone
horizontal plane (Figure 1d), at the vertical plane crossing
the two LDCF centers (Figure 1e), and inside the working
zone (Figure 1f).
The warehouse was assumed to be located in Chicago.
Simulations using the DOE's EnergyPlus whole-building
energy-modeling program were performed to determine
air and surface temperatures during winter and summer,
respectively.

Scenarios
A variety of arrangements and locations of the packing
line relative to the ceiling fans and workers were simulated
(Figure 2). The U-H-D-3 (packing line directly under
the right-side fan and oriented horizontally, two rows of
workers 0.9 m [3 ft] apart) combination in Figure 2 is the
scenario used for most of the discussion.
Figure 3 shows steady-state airfl ow distribution for
a case of U-H-D-3 at three air speeds exiting the fans
(i.e., average air speeds through the area swept by the
fan blades): 3 m/s (10 fps) (100-percent fan speed) (FS-3),
0.6 m/s (2 fps) (20-percent fan speed) (FS-0.6), and 0 m/s
(0 fps) (fans off) (FS-0). When the fans blow air downward
