Noise Level - Mitsubishi Heavy Industries SRK25GZ-L1 Handbook

8.2.7 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.
Indoor unit
Measured based on JIS B 8616
Mike position as below
(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.
