Refrigerator

A refrigerator (often shortened to fridge) or freezer is an electrical appliance that uses refrigeration to help preserve food. A domestic refrigerator is present in 99.5% of American homes. It works using phase change heat pumps operating in a refrigeration cycle. An industrial refrigerator or industrial freezer is simply a refrigerator used in an industrial setting, usually in a restaurant or supermarket.
