How to maintain the fresh air system

As people pay more and more attention to indoor air quality, fresh air systems have gradually become a standard feature in modern homes and offices. However, many users neglect system maintenance during use, resulting in performance degradation or even failure. This article will combine the hot topics and hot content on the Internet in the past 10 days to give you a detailed introduction to the maintenance methods of the fresh air system to help you extend the life of the equipment and ensure efficient operation.

1. The importance of fresh air system maintenance

The fresh air system improves indoor air quality through filtration, ventilation and other functions, but after long-term use, filters, pipes and other components are prone to accumulation of dust and pollutants. If not maintained in time, it will not only affect system performance, but may also breed bacteria and pollute the air. The following are popular discussions on the Internet about fresh air system failures in the past 10 days:

The filter is the first line of defense for the fresh air system and needs to be cleaned or replaced regularly. According to the maintenance suggestions hotly discussed across the Internet:

2.Pipeline inspection

Long-term use of pipes may accumulate dust and even breed mold. It is recommended to check the pipe tightness every six months and clean it with professional pipe cleaning tools. In a recent hot discussion, users reported that the air volume increased by 30% after duct cleaning.

3.Fan maintenance

The fan is the core component of the fresh air system. The bearings need to be cleaned and lubricated at least once a year. Maintenance data in the past 10 days show that 80% of fan failures are caused by long-term failure to clean.

4.Control panel check

Regularly check whether the control panel is functioning properly to avoid system abnormalities caused by circuit problems. Popular repair cases show that control panel failures are often misjudged as system failures.

3. Seasonal Maintenance Key Points

Depending on the season, maintenance priorities vary:

4. Professional maintenance suggestions

While routine maintenance can be completed by the user, professional in-depth maintenance is recommended every 1-2 years:

1. Heat exchanger cleaning: Only professional equipment can be thoroughly cleaned, which can increase heat recovery efficiency by 15%-20%.

2. System pressure detection: Ensure that the working pressure of each component is normal to avoid long-term overload operation.

3. Sensor calibration: Ensure the accuracy of CO2, PM2.5 and other sensors.

5. Frequently Asked Questions (Popular Questions in the Past 10 Days)

1.Q: What should I do if there is a peculiar smell in the fresh air system?

3.Q: What maintenance can I do myself?

A: Basic tasks such as filter replacement, surface cleaning, and simple functional testing can all be completed by yourself.

Conclusion

Maintenance of the fresh air system is key to ensuring its long-term and efficient operation. With regular cleaning, inspections, and necessary professional maintenance, you can not only enjoy fresh air but also save money on repairs. It is recommended to establish a maintenance calendar, record the content and time of each maintenance, and form a complete maintenance file. According to statistics from the entire network, the failure rate of user equipment that is regularly maintained is reduced by more than 60%, and the maintenance input-output ratio is extremely high.
