Summary details of the consultation 13,705,082,949 suction fan suction fan is the latest type of fan, are axial fans, because mainly used negative pressure ventilation cooling works called suction fan. Negative pressure ventilation cooling ventilation and cooling project contains two meanings, ventilation and cooling issues while addressing. Suction fan is also used in positive pressure curtain environmental conditioning, pressurized air, pressurized hair and so on. Suction fan with a bulky, oversized duct, large diameter fan, large exhaust volume, ultra-low power, low speed, low noise characteristics. Suction fan from the structure material is mainly divided into galvanized sheet steel rectangular flared glass suction fan and suction fan. All the market square galvanized sheet suction fan structure and technical parameters of the basic agreement, suction fan Model classification will be described in detail. FRP suction fan horn in different ways from the drive into a belt-type and direct-drive, suction fan Model classification will be described in detail. Details of consultation 13,705,082,949 principle of negative pressure ventilation fan exhaust suction fan outside the indoor air pressure drops, the indoor air becomes thin, forming a negative pressure zone, air flows into the interior due to the pressure difference between the compensation. In practical applications, industrial plants, centralized suction fan installed in the plant side air intakes in the plant room on the other side, the air from the intake port to the suction fan convection hair. In this process, near the suction fan to keep doors and windows closed, forcing air to flow from the inlet port side of the shop windows compensation. Air lined up orderly by the intake port flows into the workshop, from workshop flows discharged by the suction fan shop. Ventilation thorough, efficient, ventilation rate can be as high as 99%. Through specific engineering design, according to need to design ventilation rate and wind speed, any fever, harmful gases, dust can quickly exhaust smoke shop, any-time ventilation can solve the problems of poor. From a few seconds to turn on the fan for ventilation effect. Details of consultation 13,705,082,949 a suction fan cooling principle, ventilation cooling: As the sunlight buildings, machinery and equipment, the human body and other heat sources lead to the need ventilated place higher than the outdoor temperature. Indoor hot suction fan can be quickly discharged, so that room temperature and the outside temperature was flat, and will not shop inside temperature. Second, the air flow away body heat, air flow to accelerate the evaporation of sweat absorbs body heat, thus allowing the body to feel cool, and natural, like the wind cool. Third, the only negative pressure ventilation fan cooling effect, there is no cooling function, the body feeling cool. Suction fan can lower the temperature to say how many are ignorant. Fourth, and the curtain with the use of the hottest in the summer when the temperature can be controlled within the workshop 28 degrees Celsius. But the body cool feeling can be compared with air-conditioning, a little longer in front of the curtain of people will feel cold and can not stand. Details of consultation 13,705,082,949 suction fan selection (1) host installation position overall, suction fan is best installed in the middle of the building selected to minimize the air resistance of the wind pipe, shortening the length of the piping installation; if conditions as the suction fan installed in the dominant wind direction to cool the environment; (2) the suction fan can be mounted on a wall, roof, or outdoors to aerodromes, but the installation environment should ensure smooth and fresh air, especially not mounted on the smell or the smell of gas at the exhaust port, such as: toilets, kitchens, etc. If there is not enough of a door or window, you need to install special exhaust machine, exhaust suction fan to guarantee the achievement of the total air volume more than 80% -90%; (3) the suction fan mounting position, make sure it can support the weight of the entire frame structure of the main body and a suction fan blowing machine outlet pipes and maintenance personnel.
