The new wind system is based on the delivery of new wind to the interior with specialized equipment on the one side of the closed room, which is then excreted from the other side by specialized equipment and will form a "new wind flow field" inside the room, thus meeting the need for a new indoor wind break. The programme was implemented using high-pressure, high-flow wind machines, the use of machinery to send wind indoors from one side to the other, and by excretion from the other side through specially designed wind ventilators outside the room, to force the formation of new wind flow fields within the system. The air entering the room is filtered, poisoned, bacterialized, oxygenated, preheated at the same time as the wind. Priority is given to the use of fresh outdoor air to upgrade the air contaminated by residential and living processes in order to maintain the cleanness of indoor air to a lower standard. The second function is to increase internal dispersion and to prevent discomfort caused by skin humidity, which can be described as heat and comfort. The third function is to cool construction components when indoor temperatures are higher than outdoor temperatures, and such ventilation is called a cooling ventilation of buildings. Advantages: 1) to enjoy fresh air from nature without opening windows; 2) to avoid "air conditioners"; 3) to avoid impervious interior furniture and clothing; 4) to remove harmful gases from interior fittings, which are slowly released over a long period of time, in the interest of human health; 5) to recover indoor temperature and save heating costs; 6) to remove bacteria and viruses from indoors; 7) to supersonic sound; (8) to reduce indoor co2 concentrations. 9) dust protection; many causes cause indoor air pollution, and one major aspect is renovation pollution! New wind air cleaners, clean up renovation pollution! The material used in the renovation process, such as paints, marbles, plywood, plasters, slabs, interior wall coatings and adhesives, is analysed to contain organic volatilizers such as formaldehyde, benzene, ammonia, toluene, which, after being put into use, can be released continuously for years or even more, all of which are directly responsible for the excess of pm2. 5 in the interior, threatening the health of the population. Indoor pollution can also be fresher if it is managed by both sources. Wisdom chooses a new wind and air cleaner to be a good project of the times, there is a great demand for markets, and everyone starts to focus on indoor purification, bringing new opportunities for industry development!
