Product Data
12. Sound Levels
12.1 Sound Pressure Level
[Compressor Module] [Heat Exchanger Module]
Note
1. Data is valid at free field condition.
2. Reference accoustic pressure 0dB = 20
μ Pa.
3. Data is valid at nominal operation condition.
Refer to the Model Specifications for nominal conditions(Power source and Ambient temperature, etc)
4. 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.)
5. 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.
