More  and more modern industrial products, we built around the factory more  and more, in the face of the development of such a huge market, and  enhance their core competitiveness is the ventilation of each pipe  enterprises to face the problem, then from the design, production , The installation of standard ventilation system is bound to meet the  national standards, in line with the sustainable development of  enterprises planning.

For the workshop cooling and ventilation works, Suzhou Renyi  Ventilation Engineering Co., Ltd. Dingjing Li that we must first  understand the principle of negative pressure fan cooling, only familiar  with it to do the workshop ventilation works.

First,  the ventilation cooling: As the sun exposure to buildings, machinery  and equipment, the human body and other heat sources lead to the need  for ventilation than the outdoor temperature. Negative pressure fan can quickly discharge the indoor hot air, so  that room temperature and outside temperature flat, and will not  increase the temperature inside the workshop.

Second, the air flow away the body heat, air flow to accelerate the  evaporation of sweat and absorb the body heat, so that the body feel  cool, and natural wind as cool.

Third,  the negative pressure fan only the role of ventilation cooling, no  cooling function, cool is the feeling of the human body. Negative pressure fan can reduce the temperature of the argument is ignorant.

Fourth,  and the use of curtains in the summer when the hotest time can be  controlled within the workshop temperature of 28 degrees Celsius. But the body's cool feeling can be compared with air conditioning, a  little longer time facing the curtains will feel cold and can not stand.
