How to use the curve:
Trace a vertical line from maximum ambient temperature point up to internal cabinet temperature.Trace horizontal line in order to obtain corrective factor applicable to cooling capacity.
Example :
Corrective factor with ambient temperature 45°C and internal temperature 35°C should be 0.85.
An air conditioner with a nominal cooling capacity 2000W (DIN3168-L35L35) should have in these conditions cooling capacity of 2000x0.85=1700W
