What is the approximate cost of cooling the factory building?

Hello! Ventilation and cooling In the long run, it is recommended that you use Wujiang Weisheng FRP molded negative pressure fan and water curtain to cool down obviously. Exhaust air volume: 42,000-46,000 per cubic meter per hour. 0.75KW motor saves electricity, and the one-time investment cost is much lower than other ventilation equipment. You can consult. Thank you. I hope I can help you!
