HS. series
Sound power and sound pressure levels according to application range
The measurements were taken with the refrigerant R22 at an operating frequency of 50 Hz.
The calculated sound pressure level refers to free field conditions with hemispherical sound propagation at a distance of 1 m.
The tolerance for all specifications is +/- 2 dB(A).
