Hello, i need quick comparison between chilled water & package unit system specially in the power issue (power consumption & electrical requirements)?

chiller is a normal AC that uses water pips  to transfer its cold throw distances  (the water in cooled down in a heat exchanger between water and cold freon pipes)

package unit is normal DX on the roof always instilled and the cold air is transferred to the area by duct .

chiller SYSTEM always consume more KW than package system for the same TR.
