Fresh air ventilator works: fresh air system is an air purification equipment, through the exchange of indoor and outdoor air entering the indoor air purification and heat exchange process, keep indoor air fresh and smooth, fresh air ventilator is an energy saving efficient ventilation products. That is how the new wind ventilators indoor ventilation of it, we can re-wind ventilators principles to analyze the new wind ventilators ventilation function. The new wind ventilators new wind ventilators principle of the whole core of the device is a full heat exchanger, polluted indoor air is discharged into the fresh air and outdoor temperature either by heat exchange plates, while through the porous plate Humidity exchange new wind ventilators prices, so as to achieve both ventilation while maintaining indoor temperature, humidity and stable effect, which is the total heat exchange process. When running at full heat of summer cooling, the fresh air from the exhaust to get the cold, the temperature is lowered, while being dried Beijing new exhaust air ventilator, so that the new air humidity decreases; run in the winter, the fresh air from exhaust obtain heat, raising the temperature of fresh air ventilators, exhaust humidified simultaneously. ERV evaporative heat the whole works: ERV family unit is the company developed a new generation of products, applied for a national patent (patent number: ZL03269262.5) and air-conditioning equipment through a national quality supervision and inspection center. Hydrophilic aluminum foil as a carrier, body composition by a number of heat units, two units adjacent body fluid flow channel was a positive cross layout, the principle is to make indoor ventilation has not been before the heat of the core, the use of atomized water indoor ventilation endothermic evaporation enthalpy humidification first performed, to reach close to the indoor ventilation air wet bulb temperature state, then the indoor exhaust air temperature were lower than the dew point temperature of the outdoor air, and then with the outside air heat exchange to achieve the effect of cooling and dehumidification, completed a total heat exchange.
