What's going on with the fresh air system?
In recent years, as people's attention to indoor air quality continues to increase, fresh air systems have gradually become a hot topic. Especially in the past 10 days, discussions about fresh air systems have appeared frequently on social media and news platforms. This article will combine the hot content of the entire network in the past 10 days to provide you with a detailed analysis of the principles, functions, types and market trends of fresh air systems.
1. Definition and principles of fresh air system
The fresh air system is a ventilation device that can introduce fresh outdoor air into the room and discharge the dirty indoor air at the same time. Its core principle is to achieve the exchange of indoor and outdoor air through mechanical ventilation, thereby improving indoor air quality. Fresh air systems usually include air supply systems and exhaust systems. Some high-end products also have heat recovery functions, which can reduce energy losses.
2. The role of fresh air system
The main functions of the fresh air system include:
1.Improve indoor air quality: Through continuous ventilation, reduce indoor carbon dioxide concentration and reduce the accumulation of harmful substances such as formaldehyde and benzene.
2.Filter PM2.5 and dust: The fresh air system equipped with a high-efficiency filter can effectively filter particulate matter in the outdoor air, especially suitable for areas with severe haze.
3.Regulate humidity: Some fresh air systems have a humidity adjustment function, which can prevent the room from being too dry or humid.
4.Energy saving and environmental protection: The heat recovery function can reduce the energy consumption of air conditioning or heating and reduce energy waste.
3. Types of fresh air systems
According to the installation method and working principle, fresh air systems are mainly divided into the following categories:
| Type | Features | Applicable scenarios |
|---|---|---|
| Central fresh air system | Deliver fresh air to each room through pipes, suitable for whole-house ventilation | New house decoration, large apartments |
| Wall-mounted fresh air system | Simple installation, no need to lay pipes, suitable for local ventilation | Renovated houses, small apartments |
| Cabinet fresh air system | Larger volume, sufficient air volume, suitable for large spaces | Offices, commercial places |
| One-way flow fresh air system | Air exchange is achieved only through air supply or exhaust, which is low cost | Families on a budget |
| Two-way flow fresh air system | Equipped with air supply and exhaust functions at the same time, higher efficiency | Families with high requirements for air quality |
4. Market trends of fresh air systems
According to hot data analysis in the past 10 days, the fresh air system market shows the following trends:
1.Intelligent upgrade: More and more fresh air systems are equipped with intelligent control functions, which can remotely adjust the air volume and monitor air quality through mobile APPs.
2.Health needs driven: After the epidemic, consumers’ attention to healthy homes has increased significantly, and fresh air systems have become a standard feature of “healthy homes”.
3.policy support: Some regions have incorporated fresh air systems into green building standards, promoting the rapid development of the industry.
4.Brand competition intensifies: Domestic and foreign brands are entering the new fashion market one after another, and product prices are gradually becoming more affordable.
5. How to choose a fresh air system
When choosing a fresh air system, consider the following factors:
| factors | Description |
|---|---|
| Air volume | Choose the appropriate air volume according to the room area, generally 0.5-1 air changes per hour |
| filter effect | Pay attention to the filter level, HEPA filter can filter PM2.5 |
| noise | Choose products with noise levels below 40 decibels to ensure comfort during use |
| heat recovery efficiency | The efficiency of heat recovery fresh air systems is usually between 50% and 80% |
| Installation conditions | Renovated houses are suitable for wall-mounted ones, and new houses can consider central fresh air. |
6. Maintenance and maintenance of fresh air system
To ensure long-term and efficient operation of the fresh air system, regular maintenance is required:
1.Filter replacement: It is recommended to clean the primary filter once every 1-3 months and replace the high-efficiency filter every 6-12 months.
2.Duct cleaning: The central fresh air system needs to be professionally cleaned every 2-3 years to avoid dust accumulation and the breeding of bacteria.
3.Check air volume: Regularly check whether the air volume of each air outlet is uniform, and repair it in time if any abnormalities are found.
4.Heat exchanger cleaning: Check the heat exchanger once a year to ensure heat recovery efficiency.
Conclusion
As an effective solution for improving indoor air quality, fresh air systems are gradually moving from high-end residences to ordinary families. With the advancement of technology and the improvement of consumers' health awareness, fresh air systems will play an even more important role in future home life. During the selection and use process, it is recommended to choose the right product according to your own needs and house conditions and do regular maintenance, so that you can truly enjoy a fresh and healthy indoor environment.
