The air baffle and air guide grille of the air conditioner are adjusted to the maximum air
volume. The fan speed of the indoor unit is set to the highest value that the user can set
under the corresponding working conditions. The set temperature is set to the lowest
(cooling) or highest (heating) temperature allowed by the control device.
NOTE. Try to adjust the air conditioner to the state with the highest noise during normal use.
The air conditioner shall be tested under full load operation conditions, unless the
manufacturer provides special instructions or has special test requirements. For air

A.4.5.1 When testing in a rigid wall test room or a dedicated reverberation room, the
indoor and outdoor units of floor-standing air conditioners shall be placed directly on
the floor of the reverberation room. The minimum distance between any surface of the
sample and the nearest wall of the test room is 1.0 m.
When testing in an environment approximately free field above the reflective surface,
the indoor unit of the floor-standing air conditioner shall be backed against the vertical
reflective surface. The minimum size of the vertical reflective surface shall be larger
than the projected size of the measurement surface. The sound absorption coefficient of
the vertical reflective surface within the measurement range frequency is less than 0.06.
The distance between the back of the device and the vertical reflective surface is D =
10 cm ± 1 cm. The outdoor unit is installed directly in the center of the floor of the test
room. Note that the installation and positioning shall not generate additional noise. The
connecting pipes shall not affect the radiation of the indoor and outdoor unit noise.
Flexible pipe connections can be used when necessary.
A.4.5.2 When testing in a rigid wall test room or a dedicated reverberation room, the
indoor unit of a wall-mounted air conditioner is directly mounted on the wall of the test
room. The minimum distance between the bottom edge and the ground and the nearest
wall is 1.0 m. The outdoor unit is placed directly on the ground outside the reverberation
room. The minimum distance between any surface of the outdoor unit and the nearest
wall of the test room is 1.0 m. Connect the indoor and outdoor unit pipes according to
the manufacturer's instructions.
When testing in an environment close to the free field above the reflective surface, the
indoor unit of the wall-mounted air conditioner shall be installed on a rigid round tube
bracket to avoid generating additional noise. The lowest edge of the indoor unit is 1.5
m above the floor of the test room. The indoor unit is installed near the vertical reflective
surface. The distance between the back of the device and the vertical reflective surface
is D = 10 cm ± 1 cm. The vertical reflective surface shall not generate additional
vibration and noise. The minimum size of the vertical reflective surface shall be larger
than the projected size of the measurement surface. The sound absorption coefficient of
the vertical reflective surface within the measurement range frequency is less than 0.06.
The outdoor unit is installed directly in the center of the floor of the test room. Care
shall be taken to ensure that the installation and positioning do not generate additional
noise. The connecting pipes shall not affect the radiation of the noise of the indoor and
outdoor units. Flexible pipe connections can be used when necessary.
A.4.5.3 When testing in a rigid-wall test room or a dedicated reverberation room, the
apparatus shall be positioned and installed in the following manner.
- Ceiling air conditioners shall be hung inside the test room. The minimum distance
between any surface of the prototype and the nearest test room wall is 1.0 m. The
minimum distance to the top surface is 1.0 m. The outdoor unit shall be installed
on the ground ...
