2.4 Installation of Air Duct
NOTES!
①
There should be insulating layer on air-out duct, return-air duct and fresh
air duct to avoid heat loss and moisture. Adhere a nail on the air duct and
then add thermal sponge with a layer of tin. Fasten it with a nail cover and
then seal the junction with tin tapes. You can also use other materials that
have good insulation quality.
②
Each air-out duct and return-air duct should be fixed on a pre-made
board with iron frame. The junction of air duct should be well-sealed in
order to prevent air leakage.
③
The design and construction of air duct should comply with national
requirements.
④
The edge of return-air duct is suggested to be more than 150mm away
from the wall. Add a filter to the return-air opening.
⑤
Please consider noise-damping and vibration damping for the design and
construction of air duct. Besides, noise source must be away from people.
