(1) data referred to the following conditions :
internal exchanger water = 12/7°C
external exchanger air intake 35°C
(2) Total absorbed power is given by the compressor absorbed power
+ fan absorbed power + auxiliary circuit absorbed power.
(3) SCROLL = scroll compressor
(4) PHE = plates
(5) AX = axial-flow fan

The cooling performance values provided in the tables are based on the external exchanger having clean plates (fouling factor 1). For different
fouling factor values, multiply the performance by the coefficients shown in the table.
