Office buildings, large shopping malls, hotels, villas, high-end apartments... With the acceleration of social and economic development, more and more places use central air-conditioning. The concentration of these places, the use of air conditioning for a long time, the pipeline will certainly gather a lot of dust and impurities, which will have a great impact on the operation of the air conditioner and the health of the users. Therefore, it is necessary to clean the central air-conditioning pipeline regularly, then how to carry out the central air-conditioning duct Cleaning , then follow the decoration of the home network Xiaobian to understand the central air-conditioning pipe cleaning method, the central air-conditioning pipe installation matters needing attention! Central air conditioning pipe cleaning method 1. Use a robot equipped with a camera to enter the pipeline to record and record the pollution in the air duct; 2. According to the architectural drawings of the building, the customer will elaborate the pipeline cleaning construction plan and select the cleaning equipment; 3. Open the construction hole in the appropriate part of the air duct (put in the robot, seal the airbag), and block the airbags at the two ends of the two openings; 4. Connect the dust collector to one of the construction holes with a hose to create a negative pressure airflow inside the air duct to allow dust and dirt to be sucked into the dust collector; 5. Select the appropriate cleaning brush and clean the pipe with a pipe cleaning robot or a soft shaft brush; 6. After cleaning, the robot takes a photo record to confirm the cleaning quality; 7. When the cleaning quality is approved, the pipeline is physically disinfected and treated with ultraviolet rays to avoid secondary pollution; 8. Clean and move the cleaning equipment to the next section of the pipeline; re-close the opening with the same material; clean and repair the damaged insulation layer of the duct; 9. Clean the site to ensure that it does not affect the next step; 10. Qualified testing institutions shall inspect the cleaning quality according to relevant national standards; detect the air quality after air duct cleaning and disinfection; 11. On-site recovery, reinstall the disassembled air outlet, adjust the size of the air outlet to ensure the air volume; 12. According to the detailed records of the construction, the report is presented to the customer. Central air conditioning pipe installation precautions 1. The team of pipe butt welding joints should be flush with the inner wall, and the wrong amount of the inner wall of the steel pipe should not exceed 10% of the wall thickness and not more than 2mm. 2. When the components of the unequal thickness pipeline are assembled, when the inner wall fault variable exceeds 10% of the wall thickness, and is not more than 2, mm or the amount of misalignment of the outer wall is greater than 3 mm, it shall be trimmed in accordance with relevant regulations. 3. When the two pipe ends are assembled, there should be a gap between the blunt edges. The gap between the counterparts is small, and the roots are not easily penetrated; for the gap is too large, the roots are easily welded. The matching gap of the same welding joint should be uniform in all directions. However, when the horizontal pipe of the larger diameter is fixedly welded, the shrinkage of the welded joint should be considered to reduce the gap between the joints, and the gap of the flat welded portion can be appropriately enlarged. 4. Pipes with equal wall thickness, such as pipe diameter, can be fixed by the mouthpiece to ensure the correctness of the mouth and the gap between the mouth. For large diameters, the team can be fixed by spot welding angles at the end of the pipe. 5. The angle of the good interface and the matching gap of the team should be fixed after the inspection is carried out by using the welding inspection ruler or the angle gap gauge. The above is the central air-conditioning pipe cleaning method, the detailed answer to the precautions for the installation of the central air-conditioning pipe, I do not know if you are satisfied with the introduction of the decoration home network Xiaobian.
