Recently, Malaysian Chinese Mr. Han, who installed 10 Qixiang industrial fans in a home furnishing factory, told Qixiang sales staff that the weather in Malaysia was hot and the environment became even hotter after fan operation. Later, air coolers were installed on the ground of the furniture factory, but the effect was not obvious. Why does this thing happen?

After video calls between Qixiang’s technicians and Mr.Han, we learned that Mr. Han’s furniture factory had only a single layer of iron on the top, without insulation wool or insulation nets and other equipment. Under sunlight, the single-layer iron sheet becomes very hot, so the temperature of the air on the roof can reach 40-50 degrees Celsius.When the industrial fans are running, the hot air from the roof is also blown down, causing the plant to become even hotter, even if the air coolers are installed on the ground, the coverage of the air coolers is limited, so the working environment has not improved.

Originally, Mr. Han did not explain the roof facilities and on-site installation conditions when purchasing. After we understanding, the technicians of Qixiang told Mr. Han that you only need to make the industrial fans rotate in the opposite direction.

Why do Qixiang fans rotate backward could create the magical effect?

For the warehouses and factories with only single-layer iron sheets, the heat insulation effect is very poor. In summer, the factory roof temperature is very high, so the industrial fans should be rotated in the opposite direction, just like the car turns on the external circulation mode, the internal air can be circulated, and The hot air at the top is exhausted. At the same time, the air coolers are installed on the ground. The operation of the industrial fans allow the cold air blown by the air coolers to circulate throughout the plant, while the hot air on the roof is also discharged outside the house. The temperature of the whole plant is lowered, and the workers feel cool and comfortable.
