2. Installation of the plenum chamber

1) Relevant provisions on equipment static tube

a. For equipment in which air out static pressure is greater than 30Pa, hydrostatic tank must be installed on its wind pipe, for its specifications and installation, please see related provisions in GB50243-2002. b. Plenum chamber should be located in the pipe section with a smooth flow in air duct system, when the air flow velocity in the air duct system is less than 8 m/s, the plenum chamber should be located on main pipe section; when the airflow speed is more than 8m/s, they should be installed in the respective branch pipes respectively.
c. Plenum chamber is not directly installed in the air conditioner room, nor directly in the outdoors, to avoid being penetrated by the noise outside and into the pipe downstream the plenum chamber. In situations where there may be external noise, the sound insulation capability of the duct should be verified.
d. The flow rate of air passing the plenum chamber shouldn't exceed the following values:

Negative plenum chamber 5-10m/s (in high requirements:4-6 m/s);

Resonance plenum chamber 5 m/s, silencer elbow 6-8 m/s.

e. Plenum chamber is mainly used to reduce the noise from the dynamic air, anti-vibration measures should be taken to solve the noise caused by ventilator vibration.

2) Installation requirements of plenum chamber;

a. Direction of plenum chamber is installed correctly. Pay attention to loss prevention and anti-moisture.
b. The surface of perforated plates remain clean, non-corrosive, no clogging in the hole.
c. Separate brackets should be installed both in plenum chamber and in silencer corners.
d. The screws used to fasten hydrostatic tank must be uniform, smooth, no loosening, shedding in the seams.
e. The glass fiber cloth packed outside the muffler piece should be smooth, without visible scratches and corrosion.

4.9 A variety of measures to prevent cross sound between two rooms

When a main air duct is fed to multiple rooms (Figure 25a), in order to prevent "cross sound" between rooms, each program shown in Figure 25, (a) - (e) can be referred to and adopted to prevent.

1) Expand the distance between the air outlet of two chambers (see figure b):
2) Paste the sound-absorbing material (see figure c);
3) Elbow is added on air manifold in room B (see figure d);
4) Air is sent via two-way (see figure e).
