As most fans want to use in the outdoors, so on some corrosion problems blower users need full attention, hairdryer and base section after a long run and the wind and rain, easy to aging off, causing the motor to fall duct causing the accident. This is also the blower structural problems in use, the user in solving this problem is to combine professional advice must strive to make the structure more in line with the fan needs workplace. Fan coil delivery, return air way: send, return air way that the formation of the so-called air distribution, it is reasonable or not directly affect the temperature field, uniformity and stability of the velocity field of the air-conditioned room, that air conditioning is good or bad . Reasonable airflow requires a certain air velocity, air flow to avoid a short circuit, in order to guarantee a certain jet length. Wind speed depends on the outside static pressure, air volume, outlet and other factors. Outside static pressure is too low, it will lead to wind down a range of reduced room Enthusiasm, airflow design and actual operating state there is a big difference in Shanxi blower design on the graph, it should be based on the actual building structure, the room structure, depth, height, etc., choose mid-range wind, wind speed indicators to choose the appropriate fan coil model. Currently on the market Shanxi blower fan coil, various manufacturers outside static pressure value is not unified calibration differences, coupled with the use of part of the site is installed horizontal dark group, external short ducts, filters Shanxi large blowers intake and return air grilles resistance value is large, so make sure the outside static pressure 30Pa value selected for the production of Shanxi blowers, and some rooms even outside static pressure 50Pa select unit value is greater than in the actual orders about regular 20Pa resistance value, so to ensure a good uniform field in the actual operation, to achieve the desired effect empty withered.
