When a fridge is opened, warm external air gets into the main storage area and energy must be used to cool it again. LG tackled this problem with its Door-in-Door French-door refrigerator, which allowed regular-use items to be stored in a door-frame compartment. Now, the company has updated the design.

The Door-in-Door Mega-Capacity refrigerator has double-doors, both of which feature a slim compartment built in their respective frames. As with the Door-in-Door French-door refrigerator, the compartments can be opened independently of the main storage area using a button on the door handle. They can also be accessed from inside the main storage area. LG says the Door-in-Door feature can reduce cold air loss by up to 47 percent.

In addition to the Door-in-Door functionality, the Mega-Capacity refrigerator features a Fresh Air Filter system and LG's Smart Cooling Plus technology that is designed to maintain optimal temperature and humidity conditions.

LG's Smart Diagnosis technology, meanwhile, is designed to help LG's call center staff diagnose any problems that arise with the fridge over the phone. The accompanying Android smartphone app allows homeowners to "record and analyze signals from the refrigerator" to help with the diagnosis process.

As its name would suggest, the Door-in-Door Mega-Capacity refrigerator has plenty of internal storage space at 34 cu ft (0.96 cu m). LEDs are used for internal lighting and the glass finish is designed to be both aesthetically-pleasing and fingerprint/smudge resistant.

There's no word on price or availability, but the LG Door-in-Door Mega-Capacity refrigerator will be on display at CES 2015 next month.
