Workshop ventilation engineering is to use the thermal pressure formed by the temperature difference between the air inside and outside the workshop and the wind pressure generated by the outdoor air flow, so that the air inside and outside the workshop is constantly exchanged and natural ventilation is formed. In the design of the ventilation system of the workshop, the area of the intake and exhaust port must be reasonably coordinated, and the area of the intake port must be not less than or greater than the area of the exhaust port, which should be an extremely important and effective technical measure to improve the effect of natural ventilation. <br>
Try to overcome the problem of short intake flow. Ventilation equipment, Yashe brand indoor purification fresh air system uses the principle of air convection, negative pressure ventilation to design, negative pressure fan installed in the place of poor ventilation, normal work, the use of mechanical kinetic energy to make the fan run, the plant stagnant hot gas, odor, black smoke, quickly discharged in the shortest time outside. At the same time, the outdoor fresh air and indoor circulation exchange, so as to achieve the purpose of ventilation and cooling to improve the workshop environment. <br>
In addition, the ventilation system engineering of the ventilation equipment workshop must not stay just according to the established building layout, and simply determine the skylight opening area through ventilation calculation. You could say it's just negative design. Active design should be careful analysis and research, repeated trial and error, modification. Reasonable coordination of inlet and exhaust port area, and strive to obtain the best ventilation effect with the lowest economic investment. <br>
Specifically, in the design of ventilation equipment system engineering, it is necessary to first strive to achieve a lower middle and surface position under the premise of meeting the needs of ventilation volume, that is, strive to concentrate the area of the air intake in the lower working area. That is to say, it is necessary to do our best to shift the auxiliary building that is blocked against the side wall of the factory building to make room for the valuable lower side wall of the air intake. For some reason can not be moved, it is necessary to raise its lower part, the main plant to take the air intake position. On the surface, this may cost more investment, but it is worth it compared with improving the environmental quality of the plant. <br>
And even financially, it doesn't end up costing much more. Because if the air intake of the plant is blocked, the proportion of F1 and F2 will be out of proportion, and the position of the neutral surface will be increased, the exhaust pressure will be significantly reduced, resulting in a large increase in the skylight area, and the investment spent on raising the skylight may be higher than the investment in the lower part of the auxiliary building. <br>
