The latter battery is coupled to a chilled water tank (106), where the system operates cyclically in a cooling mode to utilize the former battery to cool the chilled water tank, and another cooling mode to utilize the latter battery for cooling the computer room with energy from the chilled water tank. An independent claim is also included for a method for cooling a computer room.
