New air duct installation specifications
2024-11-11
The installation specifications for fresh air ducts mainly include the following aspects:
Selection and layout: The material for fresh air ducts should be corrosion-resistant, non-toxic, odorless, and easy to clean, such as stainless steel or galvanized sheet. The layout of the ducts should be reasonable, avoiding excessive bends that could affect airflow. The diameter of the ducts should be determined based on the area and number of people in the usage location, generally requiring 100 cubic meters/hour of fresh air supply per person.
Installation requirements: The installation of fresh air ducts should comply with national standards and regulations to ensure safe use. Before installation, the interior of the ducts should be cleaned to prevent dust and debris from entering and affecting air quality. Connections should use well-sealed fittings to ensure airtightness. The ducts should be securely fixed to avoid shaking or falling. The layout should avoid other equipment and decorative components to ensure convenience and aesthetics during installation.
Maintenance and cleaning: Fresh air ducts should be cleaned quarterly to ensure air quality. During cleaning, specialized cleaners and tools should be used to avoid damaging the ducts. Regularly check if the connections of the fresh air ducts are loose; if so, repairs should be made promptly. If any damage or air leakage is found in the fresh air ducts, repairs or replacements should be made immediately.
Soundproofing and fire prevention measures: During the installation of fresh air ducts, soundproofing requirements should be considered, using soundproof materials for treatment. When fresh air ducts pass through firewalls or fire partitions, fire-blocking materials should be used to ensure fire safety.
Testing and debugging: After the installation of fresh air ducts is completed, debugging of the fresh air system should be conducted to ensure parameters such as airflow, wind speed, and pressure meet design requirements. Testing should include airtightness testing and airflow measurement to ensure normal system operation.
Usage precautions: Users should regularly replace the fresh air filter to maintain cleanliness and freshness. Before turning on the fresh air system, doors and windows should be closed to prevent outside odors from entering. When using the fresh air system, appropriate airflow adjustments should be made to avoid indoor temperatures being too cold or too hot.
By following these specifications, the quality of installation and effectiveness of fresh air ducts can be ensured, providing a healthy and comfortable indoor environment.
