The workshop is constructed of concrete, and the indoor space is very high. The large mold manufacturing machinery in the workshop produces high heat and odor during production. The company has thought of many cooling schemes to solve the high temperature and stuffy heat problem in the workshop, including central air conditioning, negative pressure exhaust, and spray cooling. However, after the final study, it was found that none of them is applicable;

If central air conditioning is installed, due to the large workshop area and high height, the overall cooling cost of central air conditioning will be very high. Moreover, the daily electricity bill in the later stage is a significant expense, especially in recent years when the economy has been sluggish. Using central air conditioning will sharply increase the cooling cost of the workshop.

2. Install negative pressure exhaust. As negative pressure fans do not have cooling capabilities, they can only be used for simple workshop ventilation and cannot actually solve the problem;

3. spray cooling is also not suitable because the mold has certain requirements for humidity.

In the end, the company's leaders found the company through a friend's introduction, and a professional ventilation and cooling team designed and installed 120 Rundongfang environmental protection air conditioners RDF23A and 40 industrial large fans, using a fan combination cooling method to provide overall ventilation and cooling for the workshop. Rundongfang environmental protection air conditioners send out cold air, which is then dispersed by industrial large fans and evenly distributed to every corner of the workshop. The entire workshop is filled with cool air, perfectly solving the ventilation, air exchange, and cooling effects of tall workshops, as well as the problem of odors in the workshop.
