Liaocheng Flextronics Ventilation Equipment Co. specializes in non-powered and non-powered natural ventilation fan and so on. Roof fan on improvement measures and design should pay attention to the problem, see today's article analysis. First, the anti-condensation: the roof fan should be designed to minimize the contact area of ??the common parts of indoor and outdoor air, reducing the amount of condensation. Engineering design for safety steel plant natural ventilation, roof fan mounting position should be avoided as far as possible above the process equipment and jobs, reducing the impact on the production of water dripping. Second, strong anti-wind areas: in typhoon-prone areas and strong winds should be used with good anti-typhoon performance roof fan, its center of gravity should be as low as possible, with streamlined structure to reduce wind drag performance, umbrella rain hat very unsatisfactory minimize the use of the structure. The advent of strong winds is non-normal conditions, rain hat design can stop the situation into account. Roof fan in the typhoon-prone areas and strong winds may also consider using the automatic installation of natural ventilation flap without power manufacturers, even in strong winds the weather, because the automatic installation will reduce the amount of aileron into the wind and rain. Aileron will return by spring mechanism in place, while the ailerons can also serve to reduce the air resistance of flow sheets role in achieving the effect of increasing the amount of wind. Third, the noise: the roof fan should have good acoustic indicators for the control of noise and fan speed should be no higher than 1500r / min natural ventilation plants to adopt 960r / min fan as well. 5000m3 / h below the roof fan noise should be controlled at 50dB less noise greater than 5000m3 / h should be controlled at 60dB or less, and should avoid high-frequency noise. Liaocheng Flextronics Ventilation Equipment Co. specializes in non-powered and non-powered natural ventilation fan and so on. Teach you without power ventilation measurement is the use of so-called measuring instruments or work it to the side of a given size of a physical quantity by a certain method. As measured by liquid column manometer pressure ventilation plant roof natural ventilation plant, centrifugal tachometer measuring ventilation speed. Measurement methods can generally be divided into two categories: 1. Those who can read directly measure directly from the ventilation test instruments measured the size of the measurement parameters, which are direct measurements. Such instruments are sometimes called direct-type instrument. Such as direct measurement using a mercury thermometer fan gas temperature. 2. Indirect measured by a certain function in terms of the size of the desired measurement parameter measurement, called the indirect side interaction. Such as when the ventilation flow, after the first read out by the Pitot tube numerical hydrodynamic its size, and then converted into ventilation flow size.
