AIRFLOW METER FOR DUCTPROBLEM TO BE SOLVED: To provide an airflow meter for a duct which readily enables arrangement of a plurality of anemometers and is capable of being attached to various ducts different in size.HORII KATSUHIKO堀井 克彦MORI KATSUHISA森 克久...
Rectangular Duct FPM To CFM Calculator + Chart.With rectangular ducts, the cross-section is calculated using the a × b equation. In this 2nd calculator, you insert these a and b (Example: 10×12 duct has a = 10 inches and b = 12 inches sides) and FPM, and you will get CFM right...
摘要: The air duct has inlet ports (1.1,1.1') and an exhaust port. A main rib (2.1) with flow guide ribs (4.1-4.3,4.1'-4.3') on both sides is arranged at the exhaust port for continuously combining and returning the air flow (6) from the inlet ports....
The cross-sectional area of an air duct must be greater than or equal to the area of the corresponding air vent on the unit. When installing an air duct, ensure that the air duct does not interfere with the maintenance door of the unit. If there are high requirements on noise, attach ...

Temperature control in a data center is crucial. DuctSox is the first directionally adjustable air displacement system for the data center industry.
Figure 3. Flow chart of the methodology used in this work [34]. For the solution of the SIMPLEC algorithm, it is necessary to establish an initial distribution of initial speed, pressure, and temperature. For temperature, an initial distribution model as a function of soil depth proposed by...
The original geometry of the battery pack was complex, so it was difficult to configure the airflow within the battery pack iteratively with the Ansys Discovery Live software. This situation could also lead to continuous errors and long simulation time. To achieve the optimum results using the so...
andBSis a temperature rise due to fan and duct heat gains. Thus, the maximum temperature differential Δtcis determined by the position of the room ratio line on the chart, since it is limited by thesaturation lineand plant operating characteristics such as the contact factor of the coil. By...
