The automobile manufacturing plant is equipped with process workshops such as stamping, welding, painting, injection molding, final assembly, and vehicle inspection. The machine tool equipment is huge and covers a large area. If air conditioning is used to cool the temperature, the cost is too high, and the enclosed space is not good for the evaporative air cooler. How can we ensure the overall good air quality inside and outside the workshop without increasing the overall operating cost of the company, create a comfortable working environment, and protect the occupational health of employees?

Aiming at the characteristics of the automobile manufacturing plant itself, an overall energy-saving cooling scheme was proposed, which effectively solved the problem of ventilation and cooling in the automobile manufacturing plant. First of all, use negative pressure fans in the high-temperature workshop. This first ventilates the workshop. It can promote heat exchange inside and outside the workshop, and can effectively discharge the air in the workshop, forming air convection to reduce the temperature in the workshop. Install a cooling pad air cooler with pipes to cool the area. The cooling pad air cooler is responsible for cooling the workshop, while the negative pressure fan exhausts the heated or turbid air in the workshop. One enters the fresh air and the other extracts the turbid and high-temperature air. A cooling pad air cooler with a negative pressure fan is an ideal project to ventilate and cool the high-temperature workshop.

After fully running the cooling pad air cooler in the automobile production workshop, the overall ventilation effect has been greatly improved. The workshop is cooler and more comfortable than before, and the unpleasant smell and dust in the past have disappeared. In addition, opening doors and windows for air exhaust is another major feature of cooling pad air cooler. The constantly changing fresh air keeps people in the natural environment at all times. There is no sense of discomfort brought by traditional air conditioning, and it can continue to pollute the dirt. The air is discharged outside to keep the indoor air fresh and natural.

After swimming or bathing, as long as the wind blows, it feels particularly cool. This is because the water absorbs heat during the evaporation process and reduces the temperature. This is the principle of the cooling pad air cooler cooling technology. The cooling pad air cooler adopts direct evaporative refrigeration technology to cool the outdoor air through a powerful evaporator in the machine. The whole process belongs to physical natural evaporative cooling, so its power consumption is extremely low, and its energy consumption is about 1/10 of the traditional refrigeration unit; in addition, its cooling effect is also very obvious, relatively humid areas (such as southern regions), generally can reach an obvious cooling effect of about 5-9 ℃; in particularly hot and dry areas (such as north, northwestern China) Area), the temperature drop can reach about 10-15℃.
