mounting-on-wall unit: built-in-ceiling unit: duct unit without auxiliary duct:
Norminal condition: indoor temperature (cooling): 27 DB/19WB, indoor temperature (heating): 20DB
Outdoor temperature(cooling): 35DB/24WB, outdoor temperature(heating): 7DB/6WB
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:
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.
Installation state: the unit should be placed on the flat floor or be mounted in horizontal direction.
Testing method:
