3.2.11 Duct Work (Indoor)
„
Operational steps
Taking Account
of Noise and
Vibration a) Canvas joints must be used between the main unit and the air suction and discharge ducts.
These fittings are designed to inhibit secondary noise resulting from the transmission of
vibrations and operating noise from the main unit to the ducts or to the rest of the building.
b) The speed of the airflow should be taken into account when choosing air suction and distribution
grills in order to keep wind noise to minimum.
„
Important points
1. The air discharge duct must be thermally insulated.
2. The canvas duct on the inlet side must be set in a metal framework.
3. The air suction and distribution grills should be positioned to take into account the possibility of
short circuits.
4. Static pressure should be checked to ensure that the airflow is within the specified range.
5. The air filter must be easily detachable.
3.2.12 Selection of Location
This unit, both indoor and outdoor, is suitable for installation in a commercial and light industrial
environment. If installed as a household appliance it could cause electromagnetic interference.
The VRV OUTDOOR units should be installed in a location that meets the following requirements:
1. The foundation is strong enough to support the weight of the unit and the floor is flat to prevent
vibration and noise generation.
2. The space around the unit is adequate for servicing and the minimum space for air inlet and air
outlet is available.
(refer to figure 1 and choose one of both possibilities)
