Sound Levels
Sound Pressure and Power Levels
SPL
The values of Sound PressureLevel SPL for every octave band frequency, measured with unit on full load
operation, at nominal working conditio ns (ambient air temperature 35_C, evaporator water inlet/outlet
temperature 12/7_C), free field conditions and 1 m from unit in according to ISO 3744 average method
are indicated in the following tables.
PWL
The values of Power Level PWL for every octave band frequency, with unit on full load operation, at nom-
inal working conditions (ambient air temperature 35_C, evaporator water inlet/outlet temperature
12/7_C), calculated in according to ISO 3744 procedure method are indicated in the following tables.
