1.International fresh air system market development history

The origins of fresh air systems can be traced back to 1956, when the British government enacted the Clean Air Act, which marked the beginning of an increase in demand for fresh air systems. The initial prototype is the low noise high static pressure blower, which can be regarded as the first generation of new air system products, that is, exhaust fans. With the passage of time, the louvered ventilation fan appeared in 1964, which is considered to be the world's first fresh air system. By the late 1970s, with the rapid development of the European economy and the improvement of the level of science and technology, people's requirements for indoor air quality are becoming higher and higher, so there is a residential microcirculation air replacement system to improve indoor air quality, referred to as VMC, that is, we usually call the central fresh air system, which marks the new air system into the second generation.

At the end of the 20th century and the beginning of the 21st century, with the increase of global attention to air pollution, the development of fresh air systems has entered a new stage. In 1989, ASHRAE formulated the "Indoor Air Quality Ventilation Code", which further promoted the development of fresh air systems. By 2000, the installation of central fresh air systems on buildings in the entire EU country has become a regulation, showing the popularity and standardization of fresh air systems on a global scale.

In recent years, with the aggravation of air pollution and the attention paid to indoor air quality, fresh air systems have not only been widely used in families, but also occupy an important position in the commercial and industrial fields. Especially in China, the market demand for fresh air systems continues to grow, promoting the rapid development of the industry. According to the forecast, the market size of China's residential fresh air system industry will maintain rapid growth in the next few years, showing the huge market potential and development prospects of fresh air system ‌.

2.International fresh air system market development trend

With the improvement of people's health awareness and the increasing emphasis on indoor air quality, people gradually realize that good indoor air quality is crucial to health and quality of life, which will continue to promote the development of fresh air system market ‌.

Government policy support for environmental protection and indoor air quality management will continue to drive the growth of the fresh air systems market. The introduction of relevant laws, regulations and policies will prompt more building owners and owners to adopt fresh air systems to improve indoor air quality ‌.

The fresh air system market is driven by technological innovation, and intelligence and energy saving have become the main trend of development. With the progress of science and technology, new types of fresh air systems will continue to emerge to meet the needs of consumers for high quality and intelligence, thus promoting the growth of the market ‌.

With the acceleration of urbanization, urban residents pay more and more attention to indoor air quality. With the increase of urban population density and the expansion of construction area, the application demand of fresh air system in public buildings, commercial office buildings and other fields will continue to grow ‌.

With the global attention to environmental protection and health issues, fresh air systems also have greater room for growth in the international market. Especially in some developing countries and regions, with the economic development and the improvement of people's living standards, the attention to indoor air quality is increasing, and the market demand for fresh air systems has shown great potential ‌. The fresh air system market has good prospects for development in the future, but enterprises need to pay close attention to changes in market demand and technology trends, and constantly improve product quality and service level to stand out in the fierce market competition ‌.
