A green building energy-saving ventilation structure

Technical Field

The utility model relates to the technical field of ventilation structures, in particular to a green building energy-saving ventilation structure.

Background technique

Ventilation structure is a system used for building ventilation. Its function is to ensure air circulation in the building to keep the air fresh, lower the indoor temperature, reduce humidity, etc. Generally, ventilation structure can be divided into natural ventilation and mechanical ventilation. Natural ventilation uses the density difference of air inside and outside the building or natural wind to make the air flow to achieve the purpose of ventilation. Mechanical ventilation uses mechanical devices to exhaust or supply air to achieve the purpose of ventilation.

As the environment becomes more polluted, the PM value in the air also increases. Therefore, most existing mechanical ventilation systems will install filters to filter the PM value in the air to improve the air quality entering the room through mechanical ventilation. However, the long-term use of the filters will accumulate and adhere to a large amount of dust, which will clog the filters and affect the filtering effect. In addition, most ventilation ducts are installed at high places in buildings, and professional high-altitude operators are required to clean and maintain them, which requires additional fees. If they are not cleaned for a long time, it will also affect the quality of the air inhaled into the room, thereby causing physical discomfort.
