Sound level [ dB(A), @ Standard condition ]
Cooling / Heating 57.0 / 58.0
Note
■ Data is valid at diffuse field condition.
■ Data is valid at nominal operating condition.
■ Reference accoustic pressure 0dB = 20μPa.
■ Sound pressure level is measured on the rated condition in the anechoic rooms by ISO 3745 standard.
Refer to the model specifications for nominal conditions. (Power source and Ambient temperature, etc)
■ Sound levels can be increased in accordance with installation and operating conditions.(Operating conditions include some functional condition like Static
pressure mode, air guide use, Room target temperature setting, etc and these functions are different in accordance with each model.)
■ Sound level will vary depending on a range of factors such as the construction(acoustic absorption coefficient) of particular room in which the equipment in
installed.
■ Refer to manual for setting dip switch of additional function.
■ In Night Low Noise Control and Noise Target Control, Capacity is tested at standard condition and 100% combination ratio.
And It will be vary depending on combination idu, environment and so on.
■ In case of setting Night Low Noise Control and Noise Target Control at the same time, Product will operate in lower conditions.(Comp Hz, Fan RPM)
