The noise level will be measured in the third octave band limited values, using a Real Time Analyser
calibrated sound intensity meter. It is a sound pressure noise level. The detailed method please refer to
the following information:
Installation state: the unit should be placed on the flat floor or be mounted in horizontal direction.
Testing method:
outdoor unit:
1.air outlet from side: the noise level is the average sound pressure level measured from front, left, right
directions.
2.air outlet from top: the noise level is the average sound pressure level measured from front, back, left, right
directions.
measured point:
H ( height to the ground) = (h (unit height) + 1m) /2
and, it is 1m to each side.
