13 MODEL, SPECIFICATION & PARAMETERS
In case any parameters in the following table are changed, no
other notice will be given. The parameters specified on the
nameplate shall prevail.
The cooling capacity of the air conditioner is measured in a
standard environment where the indoor dry/wet bulb tempera-
ture is 27°C/19°C and the outdoor dry/wet bulb temperature is
35°C/24°C; and the actual cooling capacity changes with
the rise/fall of the indoor/outdoor environment temperature and
relative humidity.
The noise of the unit is measured in the semi noise suppression
lab according to the national standards, and the accuracy extent
is ±3dB(A).
