The new air system working principle is based in a closed room side with the new equipment to the indoor air sent fresh air, and then the other side is discharged to the outside by the new wind equipment, exhibition of new wind ventilators prices in the interior will form a "new wind flow field" principle, to meet the needs of indoor fresh air ventilation. Embodiments are: the use of high head, high-volume low-power high-speed brushless DC motor driven centrifugal fan, rely on mechanical strength to indoor air, the other side with a new exhaust fan designed coerced discharged to the outside by the side the formation of new wind flow field in the system. In the air at the same time to enter the indoor air into the fresh air filter, Drugs, sterilization, oxygen, preheating (winter). After the host and exhaust heat recovery fresh air exchange, recovering most of the energy back through the fresh air indoors. Borrowing a wide range of clean space formed programs to ensure access to the indoor air is clean. With the serious process of modern industrialization, air pollution, coupled with more and more complex due to the housing structure, increasingly tight sealed room, Hall Nanjing new wind ventilators, interior decoration pollution, furniture, office environment, more and more impact on indoor air quality, it indoors "hardware" Although more and more "luxurious", exhibition of new wind ventilators installed, but the indoor air quality has become increasingly "lower", resulting in a long time indoors working or living people often appear strange or physical, mental is getting worse, so people gradually began to pay attention to indoor air quality improvement. In addition to the tightness is better or not easily ventilated place, ordinary family living also now choose to install ventilation systems, and ventilation systems in the more prominent is the new air system. Hazardous substances construction, decoration, furniture, decoration and office equipment is a major cause of the release of indoor pollution. Plus summer and winter people rely more on air conditioning to cool and indoor heating, indoor ventilation is poor, indoor harmful gas is not released and the replacement of harmful gases continue to accumulate, concentrations continue to increase, resulting in deterioration of indoor air quality, people feel sleepy, fatigue, chest tightness, and susceptible to decreased productivity, which is the World Health Organization naming "and state building syndrome", exhibition of new wind ventilators, also known as "air-conditioned." The root of these difficulties is the lack of fresh air. Use fresh air ventilator replace indoor air, keep indoor air clean, can solve these problems. Therefore, the new wind ventilators is also a "health" products.
