1.12. USE OF ANTIFREEZE SOLUTIONS
o The use of ethylene glycol is recommended if you do not wish to drain the water from the hydraulic system during the winter stoppage, or if the unit has
to supply chilled water at temperatures lower than 5°C The addition of glycol changes the physical properties of the water and consequently the perfor-
mance of the unit. The proper percentage of glycol to be added to the system can be obtained from the most demanding functioning conditions from
those shown below.
o Table shows the multipliers which allow the changes in performance of the units to be determined in proportion to the required percentage of ethylene
glycol.
o The multipliers refer to the following conditions: condenser inlet water temperature 35°C; chilled water temperature 7°C; temperature differential at
evaporator 5°C.
o For different functioning conditions, the same coefficients can be used as their variations are negligible.
o The resistance of the water side primary and secondary heat exchanger (RA-RDR accessory), the storage tank (RAS accessory) and the electric pump
unit (RAE-RAR accessory), prevents undesired effects due to freezing during the operating breaks in winter (provided the unit remains powered).
o Attention: Besides the 20% glycol, the absorption of the pump can increase with respect to the declared value (in versions P1/PR1-P2/PR2,
DP1/DPR1-DP2/DPR2, ASP1-ASP2, ASDP1-ASDP2).
