The latest refrigerator styles all feature advanced cooling systems that can save energy while offering customers ultimate climate control, keeping refrigerated food fresh longer and ensuring frozen food stays cold.

Since they were introduced in the early part of the 20th century, refrigerators have worked in generally the same way. They keep food cold by using the evaporation of liquid to absorb heat. The latest models do this basic task more precisely and efficiently, keeping food cold at optimum temperatures while keeping energy bills down.

The type of cooling system a refrigerator employs varies by brand and style of refrigerator. Basic refrigerators keep food cold. More advanced systems prevent odors from one compartment from migrating to another and allow customers to regulate the temperature in different compartments.
