9.2.3 DIAMETERS OF COOLING CIRCUIT CONNECTION PIPES
The diameters of the supply, liquid and suction pipes are identied in the order conrmation or in the following tables for
standard models (identied by the code number sequence).
The diameters provided in the table were sized considering the characteristics set forth in the following table:
Cooling line sizing criteria
Specications Supply pipes Liquid pipes
Equivalent Length (per section) 50 m
Vertical height dierence 15 m / -10 m
Cooling capacity Nominal specications as per catalogue
Evaporation Temperature 9 °C
Condensation temperature 45°C
Liquid refrigerant temperature 43 °C
Refrigerant speed Greater than 7 m/s Less than 1.5 m/s
Head loss Less than 1 Bar Less than 2 Bar
For refrigeration lines with greater equivalent lengths or greater vertical dierences, contact the manufacturer.
