External Air Intake Volume & Resistance Within Unit/
1.
Calculate the operation noise if external air is being fed by combining the noise when only external air is being fed as
shown in the diagram for operation noise characteristics and the operation noise of the unit as stipulated in the catalogue.
2.
The operation noise conforms to JIS standards and constitute measurements taken in an anechoic chamber 1.5m directly
below the indoor unit. Under normal circumstances, the diagram shown above is greater owing to the effects of surrounding
noise and reverberation when the unit is actually installed.

* The operation noise for models that use small units is lower, so use values that are within the range shown in the
above table. Using values that exceed these will result in noise when only external air is fed being louder than the
noise emitted from the unit.

Calculate the operation noise if external air is being fed by combining the noise when only
external air is being fed and the operation noise of the unit as stipulated in the catalogue.
The operation noise conforms to JIS standards and constitute measurements taken in an anechoic
chamber 1.5m directly beneath the indoor unit. Under normal circumstances, the values shown here
are greater owing to the effects of surrounding noise and reverberation when the unit is actually installed.
