Air supply duct design specifications generally assumed velocity method, Texas cooler, the main duct holding 8-10 m / s, books duct 6-8 m / s, wind the edge of the tube holding 4-6 meters / second. Air duct pipe materials are generally made of galvanized plate (white metal) also uses glass, steel, plastic duct, PP board, cloth air duct. Cooler air duct economy overall requirement is the lowest air resistance and air flow noise and energy-saving air-conditioning duct bend radius can reach the maximum value is generally less than 2 times the diameter of the duct ventilation resistance reducing elbow. Air supply piping length of piping design pressure based on different models of environmentally friendly air-conditioning different characteristics. Air conditioning air outlet pipe set actual decline takes place in Chur, socket design air volume is that the temperature must reduce the amount of it where it is needed, to determine the specifications of the wind outlet socket wind speed air flow. Blowers material plastic and aluminum products, table cold, biting wind tone pattern according to the actual situation in all its forms, is recommended to select the warm air-conditioning special socket biting wind, the average velocity of the throat control 3-6 m / sec, the recommended 4-5 m / sec. Currently cooler water resistance determining factor, Shandong cooler, such as heat transfer coefficient air resistance coefficient by touching the specimen experiment results sorted out by the empirical formula, the same structural parameters and test specimens mainly refers to material films from sheet-shaped tube from the exhaust from the row number of different sizes of the surface heat exchanger, the heat transfer coefficient of air resistance coefficient can be contacted directly experimental formula. But many manufacturers, in the user surface resistance to water heat exchanger provided by the product samples or, often experimental formula directly test specimen calculation heat exchanger surface water resistance test specimen and the same configuration parameters. The heat exchanger directly empirical formula for calculating test specimen, when the water flow rate in the branch pipe too, Shandong cooler manufacturers, water resistance is applied to a project, it found that the water system is too small, affect the normal operation, by the water resistance of this air-conditioners on-site measurement, when the water flow rate in the manifold resistance, its water resistance is much greater than the calculated value of 8K guard. _12.7 Cooler cooler cooler _ Shandong manufacturers provided by the Texas Huaxin air-conditioning plant. _12.7 Cooler cooler cooler _ Shandong manufacturers Huaxin Texas air-conditioning plant (www.wchuaxin.com) (www.wchuaxin.com) this year introduced a new upgrade, the above picture is for reference only, please call Tel or pictures on this page, for the latest information, Contact: Su Jingli.
