The cooling capacity and the compressors input power in different working conditions can be obtained by multiplying the nominal
values (PF, PA) with their respective correction factors. The diagram above indicates the correction factors; for each curve, the
relative ambient conditions, assuming that the difference between inlet and outlet cold water temperature is 5°C.
