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 air-return 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.

. The design and construction of air duct should comply with national
requirements.

. The edge of air-return duct is suggested to be more than 150mm (5-7/8in.) away
from the wall. Add afilter to the air-return opening.

. Please consider noise-damping and vibration damping for the design and
construction of air duct. Besides, noise source must be away from people. For
