FDKN-C
13.2.7 Noise level
Notes (1) The data are based on the following conditions.
Ambient air temperature:
Indoor unit 27°C DB, 19°C WB
Outdoor unit 35°C DB,
(2) The data in the chart are measured in an unechonic room.
(3) The noise levels measured in the field are usually higher than the data because of reflection.
