The most direct and effective way to turning new wind ventilators can improve indoor air pollution, improve indoor air quality is to improve indoor air circulation. Wind airflow ventilation window blind, chaotic airflow possible to bathroom and kitchen odors into the living room and bedroom, and a lot of dust entrainment, while the impact of indoor sanitation can not avoid noise pollution; the other is the use of cold and heat source facilities will result in energy waste, this attention to energy conservation in modern society is clearly undesirable. The new wind ventilators start from the supplementary fresh air, the outdoor air is introduced into the chamber, the indoor air is discharged outdoors, is an open loop system, in order to maintain a clean and indoor temperature, fresh air ventilator also includes air filtration units and heat exchange devices. Substantive features of the new wind ventilators is to polluted indoor air and harmful gases out, while coming up with sufficient fresh air, toxic gases including the following four categories: physical contamination of dust, toxic chemical pollution, biology bacterial contamination class, hypoxia pollution ventilated. On the northern spring weather, the physical, chemical class most polluted, its greatest advantage is that: the use of heat exchangers, heat exchanger through effective treatment, such as dust, soot particles in the exhaust, etc. will be a wide range of filtration, open doors and windows without conditions, to achieve the 24-hour cycle of fresh air. Since turning fresh air ventilator market is still in the market development period, many users because of funding and other issues related to still use one-way exhaust, organized or unorganized way air, or simply the use of natural ventilation, which in some Under these conditions it is appropriate, but if the room to be treated away from outdoor air or unable to effectively carry out the exchange of indoor and outdoor air, it should adopt a new wind ventilators, not only because of its distance above the ventilation problem solve, and can effectively organize air flow, heat recovery, to achieve energy saving ventilation purposes. With the improvement of people's material life, on indoor air quality requirements are also significantly improved, so the timing, quantitative organized ventilation has been more and more attention, it has also become an important indicator of the evaluation of indoor environmental quality. Fresh air ventilation function effectively outdoor fresh air by filtration, sterilization, humidification, and other processes and oxygen introduced in, while through heat recovery fresh air temperature and the indoor temperature is adjusted to basically the same, so that the indoor environment both comfortable and healthy, thus effectively improving indoor living environment.
