12.2.10 - DX Free Cooling option (Options 118A and 118B)
The DX Free Cooling option is used to produce chilled water when the ambient air temperature is lower than the temperature
of the water to be cooled, without activating the compressors [the compressors can be used for a few seconds during a Free
Cooling cycle to transfer the refrigerant charge to the Free Cooling circuit – see Operation].
Only the unit fans and a low power pump that circulates the refrigerant in the Free Cooling circuit operate to generate cooling power.
This ensures particularly high efficiency during operation in Free Cooling mode.
Option 118A (Free Cooling on both circuits) is available for units from size 220.
Option 118B (Free Cooling on one circuit) is available across the entire range.
