4) Thermal insulation of air duct
Insulation layer should be equipped on both air intake duct and return air duct, there are two kinds of
insulation materials as rubber PE and glass wool. Insulation material of rubber PE is adopted, firstly the
duct surface should be wiped clean, and then paste PE insulation materials to pipe using associated
glue; when glass wool insulation is adopted, firstly the plastic nail is bonded to the air duct, and then
attach the cotton insulation with a layer of tin tube paper, cover it with plastic nail, and finally seal the
connection port with tin filling tape,
Note:
1. Bonding density of the retaining plastic nails as shown in table 11;
2. P lease note w hen attaching the insulation layer: during cooling running, dew is absolutely not allowed
on the outer surface of insulation layer.
