Refrigeration is the process of cooling or chilling an object or substance to a temperature below its ambient environment. The term 'refrigerates' is used to describe this process, and it can be accomplished in two ways: by chilling or cooling. Chilling involves reducing the temperature of an object or substance to a level below its normal temperature, while cooling involves maintaining the temperature at a lower level than its normal temperature. Both methods are used to preserve food, beverages, and other items.
