Comprehensive utilization of resources and energy and the environment and national governments increasingly attracted attention. By the members of "professional indoor environment committee," Professor Chen Guanying editor to Tian Dexiang, Zhushou Chang, 崔九思 other famous professors and scholars prepared scientific adviser "room environment and human health," a book that more than 90% of the time indoors spent, therefore, floor fresh air ventilator, the quality of indoor air quality and human health are closely related. As we all know, human health = Air Water + nutrition + regular exercise, the four indispensable, and especially the air in contact with the most intimate human relationship most closely. Human life in the case of fasting can persist days or so, however, people in the absence of air, can only survive eight minutes, showing the importance of air for human life. First, the new wind ventilators large basic structure of the new wind ventilators mainly by the heat exchange systems, power systems, filtration systems, control systems, noise reduction systems and cabinet components. 1, the heat exchange system is, whether at home or abroad, in the fresh air ventilator using stationary and rotating heat exchangers have two forms of which also belong to Rotary rotary type heat exchanger. From normal use and maintenance point of view, static than rotary, but more than 2 × 10000m3 / h mainframe, the general can only be achieved by Rotary heat exchangers, tank new wind ventilators, it can He said stationary and rotary advantages and disadvantages. To facilitate air flow channel is arranged inside the device, in order to reduce machine size, new wind ventilators, fresh air ventilator using cross-flow, static plate heat exchanger. That is: the direction perpendicular movement of hot and cold gas, which belongs to the convective heat transfer properties of gas flow within the turbulent boundary layer. Therefore, sufficient heat exchange can achieve high energy savings. 2, filtration systems Filtration systems fresh air ventilator into early effect, in effect, sub-efficient and efficient four filters. Ventilators disposed respectively at both inlet air filter can effectively filter the air of dust particles, fibers and other impurities, effectively preventing outdoor dust and other impurities in the air into the room to achieve the purpose of purification, and to ensure that host heat exchange member is attached dirt affect device performance. 3, the control system ① fresh air ventilator use reliable electrical components, recovery fresh air ventilation machine to achieve safe and reliable operation and longevity were different air volume control. ② Depending on the use environment matching the different control methods. ③ can automatically, timing presets. 4, the inside of the noise reduction system new wind ventilators host shell paste polyethylene foam, sheet metal junctions have long-lasting sealing material, which can effectively reduce the machine's noise. 5, the housing shell with fresh air ventilator cabinet structure. Cold spray were used, different materials such as stainless steel, can also choose different materials processed in accordance with the actual needs of the user. Total heat fresh air ventilation unit, Dingrui air conditioning (certified), new wind ventilators Ltd. wucheng Dingrui provided by air-conditioning equipment. Wucheng Dingrui Air Conditioning Equipment Co., Ltd. (www.wcdrkt.com) (www.wcdrkt.com) is an industry leader in Shandong Dezhou, fans, ventilation equipment, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness , the maximum meet customer needs. In Dingrui air conditioning leadership with the staff warmly welcome all inquiries negotiations to create Dingrui air conditioning better future.
