How to solve the problem of cooling and ventilation in waiting room with industrial ceiling fan

How to cool down the sorting center

Two days ago, our salesman went to a well-known large injection molding factory to explore the factory. As soon as he came back, he told me that the factory was really big, with nearly 5000 square meters. In a workshop, there were hundreds of injection molding machines. However, the working conditions were also quite bad. As soon as we entered the injection molding factory, the temperature was very high, which was several degrees higher than that outside, and there was a strong odor. All the employees wore masks at work. After listening, I was quite curious about how to cool down the accommodation workshop in such a bad environment? What kind of cooling scheme should be designed to solve this problem?
