The story of the Qixiang HVLS fans | fansqx.com

When a person thought of  HVLS fans  they would have been thinking of a ceiling fan of 24ft in diameter. Those ceiling fan sizes have rapidly become small in size considering the sizes that are popular in residential ceiling fans today. Not too many years ago, a company fans came onto the scene selling extra large ceiling fans that use a gearbox and long extruded aluminum blades, which they call airfoils, with spans of  anywhere from 8 feet to over 24 feet. These  ceiling fans  became very popular in large warehouses. Many customers who had seen these fans began to want the same style for huge open spaces in their own homes. The problem was (and still is) the weight requirement for hanging the large industrial versions of these warehouse fans. These industrial ceiling fans have to be mounted onto steel I-beams, and many times required three to four people to install them due to the weight factor alone. Residential houses simply just don’t have the prope...

How HVLS Fans Function in a Logistics Facility

About How  HVLS Fans  Function in a Logistics Facility Warehouses and logistics facilities generally encompass massive square footage filled with machinery, people and even light fixtures that all give off heat. These spaces can suffer from climate zones, poor air quality and uncomfortable temperatures that can cause both energy inefficiencies and safety concerns for managers to mitigate. If you are a Warehouse or Facility Manager looking at HVLS fans as a solution for your building, there are important features of HVLS fans that you need to examine when finding the solution to best fit your facility’s needs. Logistics facilities require speed and pacing. This type of activity and traffic builds heat in a variety of climates.

Why do Qixiang HVLS FAN only have 5 blades instead of more?

  ​Longer blades will create a wider column of air that is pushed downwards by an  HVLS fan . Airflow research conducted by Ramadan Bassiouny and Nader S. Korah published in a 2011 issue of Energy and Buildings showed that the maximum amount of airflow comes from the midpoint of a fan. Airflow is lowest in the center of the fan and at the very edge of blade tips. This is why you don’t feel as much airflow when standing directly under a ceiling fan as you would if you were standing slightly to the side of its hub. More blades might improve the velocity of air moving through the fan, but they don’t do anything to widen the column of air pushed out by the fan. Having more blades also increases the fan’s energy consumption. 1. The number of blades on a  ceiling fan  is important to its performance. While additional blades create more airflow fan weight and drag also increase, which requires the fan motor to work harder. Studies show that the airf...
