As the wind blows, exhaust air flow from the first cooling tower row is forced to bend downwards causing recirculation
in the area between to the two cooling towers rows.
test was implemented at three sites in the landfill.
Public aquatic facilities can perform regular challenge tests of chemical feeder interlock systems (e.g., regular measurement of time for the interlock to shut off chemical feeders after the recirculation
pump turns off), and conduct these tests when no bathers are in the pool.
The 800 K experimental PIV results are shown to follow similar phases as the 573 K results, however, a major difference is that the recirculation
velocity is quite low and the axial velocity becomes positive very quickly.
The salt stress decreased shoot dry matter production of plants regardless of the hydroponic system and NS recirculation
frequency (Figure 2), the reductions were more pronounced in the NFT system (45%) compared to the DFT system (10, 38 and 30% for the frequencies of 0.25, 2 and 4 h, respectively).
flow (R), shown in Figure 2, refers to air that is drawn from the IT equipment exhaust back to the server inlet without returning first to the CRAH for cooling, resulting in elevated server- inlet temperatures.
The one-stage desiccant cooling system under two modes of ventilation and recirculation
and the two-stage desiccant cooling system under two modes of ventilation and recirculation
were considered to evaluate the four types of desiccant cooling system.
Configured as a neutral pressure room, this system ensures 100% recirculation
of exhausted air and complete protection of the external environment
A quick sound test, with the pointed end of a screwdriver held against the recirculation
line pipe and the handle end against my ear, produced high-frequency noise, an indicator that the flow velocity noise in the pipe is much higher than reasonable.
One study by Goldner found that constant speed pumps controlled by a recirculation
line aquastat reduce water consumption, decrease delivery time, increase temperature, and save money.
The tip has two complementary features that enable high flow and reduce recirculation
. First, the openings are reversed to better use blood flow dynamics within the heart.
