Fan coil cooling capacity Q, coil heat transfer coefficient K, face velocity V fan coil cooling capacity Q, coil heat transfer coefficient K, face velocity V, the following relationship exists between the static pressure Pj: QαKα Vα1 / Pj. Second, of course, the connotation of wind Lα face velocity V, the static pressure and air flow between the two are as follows: First, Xiangfen fan coil units, fan coil units, such as a static limit under 30Pa, static pressure and proportional relationship between the amount of wind! This time for the maximum static pressure 30Pa fan coil can provide an air volume of the third gear speed corresponding to the maximum amount of wind profile, with the number of files to reduce air flow and static pressure also decreases. This is due to the same motor output power by changing the motor speed control is achieved for. It should be noted at this time the fan coil cooling capacity is directly proportional to the relationship between the Q and the static pressure Pj's, fp204 fan coil units, namely QαKαVαPj. Second, different static pressure fan coil limits as 30Pa, 50Pa, inverse relationship between the static pressure and air flow! This is because the same motor output power conditions, by switching between the dynamic pressure and the static pressure is achieved, fp238 fan coil, the higher the static pressure corresponds to a smaller amount of wind. On the relationship between this point and static pressure fan coil cooling capacity Q Pj already analyzed above a total pressure = static + dynamic pressure, static pressure in the physical density dependent? Dynamic pressure air density = 0.5 * ^ * Winds More than 2 ?? pressure = total pressure - resistance of each device within the system analysis for pressure pipe resistance curve to be analyzed according to the fan performance curve and piping. Fan coil cooling capacity, fan coil heating capacity, three rows of pipe fan coil; fan coil air flow pressure; low static pressure fan coil, high static pressure fan coil units, fan coil fan coil vibration noise out of the water direction Great solution or damaged fan bearings poor lubrication, too much dust or damaged fan blades, fan impeller and casing friction, an external outlet duct or outlet is not soft connection, coil and drip tray with supply and return pipe drain connection is not soft, fan coil run in high gear, fixed fan connector loose outlet louvers loose 'forms: vibration and noise is too large Xiangfen fan coil units, air-conditioning equipment Hao Yang, fp136 fan coil the Texas Air Conditioning Equipment Co., Ltd. Hao Yang. Xiangfen fan coil units, air-conditioning equipment Hao Yang, fp136 fan coil Hao Yang Texas Air Conditioning Equipment Co.
