I have a split units that their Rc is above 5 mentioned in the Reference Guide, but fortunately my average refrigerant atmospheric impact is lower than 100 (according to use efficient centrifugal chillers). Now can I get this credit or not?

If the calculations show that your impact is lower than 100, you can earn the credit. Typically, its the use of split systems as the only HVAC system that makes the credit difficult to achieve.
