1.1.7 Installation of air pipes and openings
Caution:
‹ The air supply pipe, the air intake pipe and the fresh air pipe must be covered with a layer of thermal
insulation, so as to avoid thermal leakage and condensation. Firstly apply liquid nail on the pipes, then attach
the thermal insulation cotton with a layer of tinfoil. Use the liquid nail cover to fix it. Lastly use tinfoil
adhesive tape to carefully seal the joints; other good thermal insulation materials can also be used.
‹ The air supply pipes and the air intake pipes shall be fixed to the prefabricated boards of the ceiling by using
iron supports. The joints of the pipes must be sealed by glue so as to avoid leakage.
‹
The design and installation of air pipes must be in conformity with the relevant state engineering criteria.
‹ The edge of the air intake pipe must be at least 150mm away from the wall. The air intake must be covered
with filter.
‹ Silencing and shock absorption shall be considered in the design and installation of the air pipes. Additionally,
the noise source must be far away from where people stay. The air intake shall not be located above the place
where users stay (offices and rest places, etc.).
