The nominal Free Cooling capacity is obtained when all compressors are OFF, the return water temperature from the system is 15°C and the ambient temperature is 2°C. to calculate the free cooling capacity in different conditions please refer to the above diagram. To obtain free cooling duty multiply the nominal Free Cooling capacity by the CFC factor obtained.
