In the design and implementation of clean room engineering, there are some small details, we need to pay more attention, otherwise it may spend a huge amount of money and energy and the completion of the project did not achieve the desired effect, influence the quality of the products:
     First, the air conditioning and purification need to pay attention to energy saving:
     Air purification is the major energy consumers, should pay attention to in the design and construction of energy-saving measures in design, and the regional division of the system, air volume calculation, to determine the temperature and relative temperature, determine the level and number of air exchange, clean fresh air ratio, air duct insulation, wind pipe production in the form of the bite effect on the air leakage rate effect of branch pipe connection, angle of airflow resistance, whether the air leakage of the equipment and the flange connection box, air conditioning fan, water chiller selection without relating to energy consumption, therefore, these details must be considered.
       Two, the wind pipe requires both economic and efficiency
     In the concentration or purification of air conditioning system, the air duct is both economical and effective air, the former is reflected in the low price, convenient construction, operation cost, smooth surface resistance is small, the latter refers to good tightness, no leakage, no dust, no dust, no pollution, can fire resistance, corrosion resistance, moisture resistance, local resistance in operation, sometimes much higher than the pipe resistance along the duct, this situation needs to be improved, the main pipe elbow, tube and pipe three through four, the center of curvature radius elbow should be larger than the rectangular duct with circular edge length, 1.25 times the diameter of diversion pipe should be added in large section duct, in order to reduce the resistance, and in the actual installation, less so, for the tube, not all of a sudden diameter should be gradually expanded into (shrinkage) tube diffuser on each side of the propagation angle Should be more than 15 degrees, reducing pipe per edge contraction angle less than 30 degrees and rectangular duct three through to reactor bend diversion, Shenzhen central air-conditioning engineering branch should also have a radius of curvature to 90 degree angle diversion, should add deflector in the elbow.
       Three, should be based on the local climate conditions to choose the air conditioning box
About the air conditioning box choice, should consider the climate environment, such as the low temperature in winter, containing a large quantity of dust in the air of northern area, it should be added in the air preheating section of general air conditioning unit, the spray type air handling mode, which not only on the air and dust to produce heat exchange to achieve the temperature and humidity requirements, and in the humid climate, air dust concentration is low in the south of China, winter is also no need to preheat fresh air, filtering and adjustment of the temperature and humidity of the air is the primary filter table, cold temperature and humidity regulation, also can strengthen the temperature and humidity reduction process, and then by the filter and terminal efficiency or high efficiency filter, air conditioning fan box supporting the best use of the frequency conversion fan, which not only energy, also can adjust the air flow rate and pressure.
