The new wind ventilators new wind ventilators main technical parameters: ① way ventilation: it determines the size of the ventilation or air changes, the common unit: m3 / h. Ceiling fresh air ventilator unit ② residual pressure: its size determines the distance or overcome the resistance of air capacity, the common unit: Pa. ③ Noise: Common units: dB (A). ④ Power: determines the size of the power consumption of air conditioning new air handling units, unit: W or kW. ⑤ heat transfer efficiency: the ratio of the reaction unit or heat recovery efficiency, unit:%. ⑥ structural parameters: the dimensions and installation / with the size, it is subject to restrictions on the installation conditions. The new wind ventilators is a new ventilation equipment, but new wind ventilators to polluted indoor air discharge out fresh outdoor air will enter the room, fresh air ventilators and other air cleaning devices, the fresh air ventilation Machine is an open loop system, the new air unit installed indoors can provide fresh outdoor air through the filter, with enough fresh air, people in the room can also be a pager to high-quality, fresh, clean air, these Fresh air is rich in oxygen, is conducive to human health. The new wind ventilators what purpose? The purpose of the new wind ventilators: Provide the required air to breathe; dilution of odor; to remove excess moisture; dilute indoor pollutants; provide air needed for combustion; adjust the room temperature. Second, the raison d'etre of the new wind ventilators: not only to keep indoor air clean, but also save energy, but also the humidity, sterilization and other functions via the additional thermostat, new air unit can be used for all kinds of indoor places, so although new wind ventilators market is still in the development stage, the new wind generating units, but it is also inevitable and air conditioning, as slowly being recognized, accepted, and widely use. In order to protect human health, the prevention and control of indoor air pollution, China in March 1, 2003 promulgated the national standard GB / T18883-2002 "indoor air quality standards", which is not only inevitable demand to improve people's lives brings, but also human society forward the inevitable trend of new wind generating units, Dingrui air conditioning, a full hot new wind generating units provided by wucheng Dingrui Air Conditioning Equipment Co., Ltd. Wucheng Dingrui Air Conditioning Equipment Co., Ltd.
