I believe Jinxiang Yun plant cooling ventilation equipment plant cooling ventilation must be your best choice to install equipment to identify the number of units from the fans and the suction fan: Fan Fan output is based on the amount of wind and the diameter is proportional to the size of the basic fan page, follow the room an area the size of the selection, but the output air flow fans are generally very small, very small area of ??the tube how much air conditioners are generally required to hold a lot. Suction fan is used to calculate the number of units installed according to the customer's size, the amount of negative pressure ventilation fan from 28000-52000m3 / h, which is popular in general terms a typhoon function room 50-160㎡ the tube. ★ from the fans and to identify the effect of suction fan: Fans at work can only be effective locally, II suction fan is the overall effect of the environment. ★ suction fan from fans and operational costs to identify: Although single fan cafe with very low power consumption of the chiller, but because it is a single ineffective, the installation will generally be more than one, so that relative to negative air compressor station in terms of a suction fan can resist a lot of desk fan. Nanchang Jin Xiangyun plant cooling ventilation equipment is a professional sales suction fan, cooling water curtain, chiller suppliers.

I believe Jinxiang Yun plant cooling ventilation equipment must be your plant cooling ventilation equipment the best choice. Fan air volume and pressure is where we first learned to look at the concept of air volume and pressure, the air volume actually refers to an area with ventilation fan flat rate product. The ventilation area is subtracted from the value of the projected area of ??the outlet area of ??the tongue at the vortex obtained, the plane is the velocity of the air flow rate through time. When the plane speed is constant, the greater the ventilation area, which is the larger outer diameter of the impeller blade cooling fan, the greater the amount of wind. The larger the amount of wind, the air, the greater heat absorption, thermal effect is more obvious fan. The air pressure is to be able to normal ventilation, equipment needed to overcome the resistance, we change the value of the measured pressure will generally referred to as static pressure to use the chiller plant, it is the pressure of the gas parallel to the surface action of the object, mainly perpendicular to its surface utilizing the hole measured out. In practice, that is not to say that strong ventilation air volume capacity. Also take into account is the main air flow, air flow path in its encounter obstacles, so when the wind increases, pressure decreases. Sometimes in order to reduce the system impedance, even the choice of a smaller size fan, also can obtain the same amount of wind.
