In cold seasons, people close doors and windows in order to keep warm wells warm and use less air, and their faces become flushed, thinking it's warm, but actually lacking oxygen. In hot seasons, people close doors and windows in order to keep cold and use less air, and they feel listless, thinking it's fatigue, but actually lacking oxygen. In recent years, as the quality of doors and windows has become increasingly high and the tightness has almost reached the limit, oxygen deficiency has become increasingly serious. In modern buildings that appear to be full of high-tech colors, the ventilation system still adopts the traditional "low technology" mode, which will bring great harm to people's physical and mental health.

Hazards of low tech ventilation modes

Traditional ventilation systems generally use filters that cannot filter fine dust. Ventilation pipes are extended to every room, a large building, and the air pipes are dozens of kilometers long. They are diverse and complex, constituting a huge source of pollution. Due to the delayed cleaning process, there is often a large amount of bacteria breeding here, even more dirty than the sewer. This traditional ventilation setting generally adopts the "three seven open" mode, That is, 30% of the entire ventilation system uses outdoor fresh air and 70% uses indoor return air, resulting in cross contamination. People in the entire building "breathe together and share weal and woe.". In addition, due to technical defects in traditional ventilation settings, the air inlet and exhaust openings are often too close. Generally, carbon dioxide sensors are not installed, resulting in uneven distribution of fresh air. In some places, there is a lack of fresh air, and in some places, there is excessive fresh air. Unabsorbed fresh air (cold and warm air) is blown away in vain, "The lack of fresh air in a room can lead to hypoxia, increased blood oxygen deficiency, and an increase in the concentration of carbon dioxide. This can cause significant headaches due to insufficient blood supply to the brain, as well as symptoms such as chest tightness, cold hands and feet, and drowsiness. Frequently living in a hypoxic environment can easily lead to rough skin, premature aging, decreased memory and thinking abilities, and lead to diseases such as heart disease, brain damage, and stroke." Yuanda Air Purification Department related technical personnel said.

Yuanda New Technology Solves Indoor Pollution Problems

The rich people ignore the tiredness of the journey and travel thousands of miles to places with clean air for vacation, while the ordinary people have to consider the cost. "In fact, regardless of poverty or wealth, humans need clean air, especially ordinary people." Zhang Yue, chairman of Yuanda Group, said. It is understood that the world's medical costs for air pollution far exceed those of any other disease. Air pollution makes the rich unhappy and the poor poorer.

Is there a simple and inexpensive technology for humans to obtain clean air? This is the mission that Yuanda has been exploring for, and Yuanda has created this technology. Yuanda has applied electrostatic dust removal technology to fresh air systems, achieving amazing innovation. Electrostatic dust removal is not a new technology. In the past, it was mainly used for the final dust removal of power stations. The ambitious innovation refers to the possibility of becoming a popular technology. Broad patents include structures with large dust collection capacity but small size; Third gear current regulation, using different degrees of pollution sites; Electrostatic constant current and constant voltage output, which is not easy to generate motor noise in any humidity environment, and is absolutely safe. These innovative actions have made it easy for people to obtain dust-free and sterile air from now on. Yuanda Fresh Air System has a unique feature. Its direct fresh air system directly introduces fresh air from outside the wall, allowing outdoor air to exchange with indoor air. The exhaust duct system introduces purified fresh air into the room through public spaces such as corridors. The exterior wall does not have openings, which does not affect the appearance of the building and maximizes energy conservation. Yuanda can achieve this design in a myriad of buildings, providing dozens of products and installation accessories.

In addition, small footprint is one of the important features of Yuanda's fresh air system. Its "real connected fresh air system" hardly occupies space. "The exhaust duct system occupies 50% less space than similar products." The space cost saved may be worth more than the equipment purchase fee, "said a technician from Yuanda's fresh air system technology department.

"Using less energy and lower investment than ever before to comprehensively solve the problem of fresh air, allowing every building and every house to breathe freely, which is the constant pursuit of Yuanda.".
