Semi-hermetic compressors VARISPEED
The measurements were taken with the refrigerant R449A.
Evaporation temperature to = -10°C, condensing temperature tc = 45°C, suction gas superheat Δtoh = 20K.
The calculated sound pressure level in the last column refers to free field conditions with hemispherical sound propagation at a distance of 1 m.
The tolerance for all specifications is +/- 2 dB(A).
