Frozen ventilation opportunities encountered problems
1. The distance between the indoor air outlet and the return wind mouth is too small. The air supply pipe is positive pressure. The backwind pipe is negative pressure. The air flows to the negative pressure. The newly introduced fresh air is quickly discharged outdoors.The fresh air system has almost no effect.
Countermeasures: Extend the pipeline to each house, and set the position of the return air inlet and airport according to the airflow organization.
2. The fresh air system of the simple device has no supporting purification system. The fresh air introduced indoors is still air with poor air quality.
Countermeasures: Buy a three -level filtering fresh air gas exchange machine, filter and capture pollutants in the air, remove PM2.5 in the air, and ensure that the indoor air is fresh and clean.
3. The distance between the outdoor air vent and the return wind is too small, causing the dirty air discharged from the room to be re -introduced into the room.
Countermeasure: If the condition is promised, set the air outlet and the return air outlet on different walls to avoid short circuit of air flow.If the conditions are limited, the distance from the air outlet and the return air outlet is at least 2 meters on the same wall.
4. Error planning for the location of the air outlet.
Fresh air air -changing machine is placed in the kitchen or the bathroom ceiling.The first is because there will be a certain noise when the fan work, especially the strong stall.The second is that in most cases, the fan is a part with a high demand.
