Fresh air ventilator is based in a closed room side the other side of the wind blowing fresh air ventilator, the principle in the room will form the "new wind flow field" was designed and developed. It relies on mechanical air, the wind, forcing the formation of new wind flow field within the system. A time to keep indoor air clean and fresh new environmentally friendly appliances. This independent indoor air exchange, purification circulatory system sensible heat fresh air ventilator, can fresh air ventilation units, enter the exclusion of natural fresh air indoor air pollution at the same time, will enter the interior of the new wind first by filtration, sterilization, heating, 2. aerobics and many other processed fresh air ventilator performance should meet the requirements of Table 1. Ceiling fresh air ventilator, the device corresponding nominal amount of wind heat exchange efficiency value of not less than the requirements of Table 2 of 3. In general, the new air temperature at about -10 ℃, the exhaust side frost may occur, can be set up in front of the air preheater unit. 4. The device should be chosen to meet the relevant requirements of other standards and specifications.
