How to position industrial fans and decide the quantity of fans? Generally, it is reasonable to keep the space between 15 meters and 25 meters for each two RTFANS industrial HVLS fans. In such an area, it can achieve an ideal ventilation and cooling effect. The ventilation and cooling effect of industrial HVLS fans mainly depends on the following three facts.
First, the distance between the fan blades level and the roof-this area is called the gas storage area. According to related calculations, the optimal height of gas storage area is over 1.1 meters. RTFANS industrial HVLS fan can produce a tremendous amount of air- about 13,000 cubic meters per minute. If the height does not reach the ideal state because of travelling crane or roof height restrictions, it will reduce the air volume per minute because of insufficient gas storage area volume. In this case, we should increase the density of fans.
Second, the height of the fan blades level from the ground. This height determines the coverage of the wind. When the height of the fan blades level from the ground is lower than 6 meters, the wind pressure is stronger, but the coverage area is small. Therefore, if the height of the fan blades level from the ground is lower than 6 meters, it should appropriately increase the fans density according to actual needs to get a relatively perfect coverage; the best installation height of the RTFANS HVLS Fans is that the fan blades level is 7-9 meters away from the ground ,in this range, the air volume, coverage, and comfort can achieve the best effect; When the height is 9-13 meters, the wind pressure is slightly lower, and it has no obvious effect on the ventilation and cooling effect. But when the fan blades level is 14 meters or more above the ground, it will significantly reduce the effect. Try to avoid the fan blades level at this height.
Third, the ground layout and structure. If the structure is very complex, for example, there are more ground equipment and partitions, it will obstruct the air circulation to a certain extent and greatly affect the ventilation effect. Here, we should increase the fans density according to the actual situation.
