Fresh air ventilator air heat recovery, according to the type of air heat exchanger can be divided into plate, plate-fin, Rotary, and other types of heat pipe wind chassis, according to the nature of the recovery of heat into sensible heat recovery unit and full heat recovery. Currently, the new wind ventilators on the market generally refers to the plate-fin air sensible heat recovery unit. Rotary full heat recovery products also have the Texas wind chassis manufacturers, but because of higher prices, the application is also less. Plate (plate-fin), a wholly foreign long heat recovery products, but the price is higher, the domestic manufacturers are said to have been developed. Good ventilation is to dilute the advantages of a variety of indoor pollutants, effective way to improve indoor air quality, fresh air ventilator, while the supply of fresh air to displace the same amount of air polluted indoor air box price, but usually the fan coil (fcu) plus new air conditioning system in the best wind chassis manufacturers, set up a separate air system were sent to the room, extra room air by positive pressure to exclude, in some closed tight building, possible shortage of fresh air, from one hand used in the air conditioning system instead of a new wind ventilators new air handling units supply fresh air is an advantage, there are also many examples of such applications engineering.
