2. Scientific ventilation schedule (based on meteorological data)
| time period | Ventilation recommendations | PM2.5 average | Humidity reference |
|---|---|---|---|
| 6:00-8:00 | Best (fresh air) | 35-50 | 65%-75% |
| 9:00-11:00 | It is recommended to open the window | 50-80 | 60%-70% |

3. Ventilation solutions for different house types
1.North-south transparent house type: To form linear convection, the window area is recommended to be 1/6 of the room area. In summer, fans can be used to enhance airflow.
2.Single side lighting unit: Adopt the "diagonal ventilation method", open the farthest windows at the same time, and use the exhaust fan to increase the efficiency by 40%.
3.LOFT apartment type: Utilizing the principle of hot air rising, air is taken in from the lower floor and exhausted from the upper floor, and the stairwell must be kept clear.
4. Comparison of popular ventilation equipment
| Device type | price range | Applicable area | ventilation efficiency |
|---|---|---|---|
| Wall mounted fresh air fan | 2000-5000 yuan | 15-30㎡ | 60m³/h |
| Central fresh air system | 15,000-30,000 yuan | 80-150㎡ | 300m³/h |

5. Solutions for special scenarios
1.Ventilation after decoration: Adopt the "5+2+2" rule - 5 days of airtight heating to accelerate formaldehyde release, 2 days of strong ventilation, 2 days of activated carbon adsorption, cycle.
2.rainy season: Open the window 3 times a day, 30 minutes each time, and use a dehumidifier to keep the humidity below 60%.
3.high-rise residential: Pay attention to the "wind pressure effect". It is recommended to install a child safety lock and open the window at an angle of no more than 15 cm.
According to the latest research data, scientific ventilation can improve indoor air quality by 3-5 times while reducing air conditioning energy consumption by 30%. It is recommended to choose the most suitable ventilation solution based on the actual situation of the house.
