定期清洁保养：定期对通风管道进行清洁，可有效去除管道内积聚的灰尘、污垢、油污等杂质，保证通风系统正常运行，提高室内空气质量。对于中央空调通风管道，建议每年至少进行一次全面清洁。清洁时，采用专业的管道清洗设备，如机器人清洗设备、高压水枪等，对管道内部进行彻底清洗。在清洗过程中，注意保护管道内壁，避免造成损伤。对于厨房排烟通风管道，由于油烟积聚较快，清洗频率应更高，一般每季度或半年进行一次深度清洗，防止油烟积聚引发火灾隐患。同时，对通风系统的过滤器进行定期更换或清洗，确保其过滤效果，减少杂质进入管道。

Regular cleaning and maintenance: Regularly cleaning the ventilation ducts can effectively remove impurities such as dust, dirt, and oil accumulated inside the ducts, ensuring the normal operation of the ventilation system and improving indoor air quality. For central air conditioning ventilation ducts, it is recommended to conduct a comprehensive cleaning at least once a year. When cleaning, professional pipeline cleaning equipment such as robot cleaning equipment and high-pressure water guns should be used to thoroughly clean the inside of the pipeline. During the cleaning process, pay attention to protecting the inner wall of the pipeline to avoid damage. For kitchen exhaust ventilation ducts, due to the rapid accumulation of oil fumes, the cleaning frequency should be higher. Generally, deep cleaning should be carried out once every quarter or six months to prevent the accumulation of oil fumes from causing fire hazards. At the same time, the filters of the ventilation system should be regularly replaced or cleaned to ensure their filtering effect and reduce impurities from entering the pipeline.

检查与维修：定期对通风管道及相关设备进行检查，及时发现并处理潜在问题。检查管道外观是否有破损、变形、腐蚀等情况，对于镀锌钢板风管，若发现镀锌层脱落、出现锈斑，应及时进行修复或防腐处理；对于无机玻璃钢风管，注意检查是否有裂缝、酥裂等问题，如有需及时修补。检查管道连接部位，确保密封垫完好，螺栓无松动，防止漏风。对风机、阀门等设备进行检查，查看其运行状态是否正常，零部件是否磨损、老化，如有问题及时更换。在检查过程中，发现的小问题可及时进行现场维修，对于较为严重的问题，需制定详细维修方案，组织专业人员进行维修，确保通风系统尽快恢复正常运行。

Inspection and Maintenance: Regularly inspect ventilation ducts and related equipment to promptly identify and address potential issues. Check the appearance of the pipeline for damage, deformation, corrosion, etc. For galvanized steel sheet ducts, if the galvanized layer falls off or rust spots appear, timely repair or anti-corrosion treatment should be carried out; For inorganic fiberglass ducts, pay attention to checking for cracks, crisps, and other issues, and repair them in a timely manner if necessary. Check the connection parts of the pipeline to ensure that the sealing gasket is intact, the bolts are not loose, and prevent air leakage. Inspect equipment such as fans and valves to ensure their normal operation, wear and aging of components, and replace them promptly if there are any issues. During the inspection process, minor issues discovered can be promptly repaired on-site. For more serious issues, a detailed repair plan needs to be developed and professional personnel organized to ensure that the ventilation system resumes normal operation as soon as possible.

应对特殊情况：在遇到自然灾害，如暴雨、地震等，或建筑物进行改造、装修等特殊情况时，要对通风管道系统进行特别检查与维护。暴雨后，检查通风管道是否有进水情况，如有积水及时清理，并对受潮的管道及设备进行干燥处理，防止生锈、腐蚀。地震后，对通风管道的支架、吊架进行全面检查，查看是否有松动、变形，对受损的支撑结构进行修复或加固，确保管道安全。建筑物改造、装修过程中，要注意保护通风管道，避免因施工碰撞、损坏管道。若涉及通风系统的改造，需由专业设计人员进行方案设计，并严格按照施工规范进行施工，确保改造后的通风系统性能满足要求。

Special circumstances: in case of natural disasters, such as rainstorm, earthquake, or special circumstances such as reconstruction and decoration of buildings, special inspection and maintenance shall be carried out for the ventilation duct system. After the rainstorm, check whether there is water in the ventilation pipe. If there is water, clean it in time, and dry the damped pipe and equipment to prevent rust and corrosion. After the earthquake, conduct a comprehensive inspection of the supports and hangers of the ventilation ducts to check for any looseness or deformation. Repair or reinforce the damaged support structures to ensure the safety of the ducts. During the process of building renovation and decoration, attention should be paid to protecting ventilation ducts to avoid collisions and damage caused by construction. If it involves the renovation of the ventilation system, professional designers need to design the scheme and strictly follow the construction specifications to ensure that the performance of the renovated ventilation system meets the requirements.
