A refrigerator is a common household appliance used to store food and drinks at a cool temperature. It is composed of four main components: a FRIDGE, a FREEZER, a CHILLER, and an ICEBOX. The FRIDGE is the main component of the refrigerator and is used to store food and drinks that need to be kept at a cool temperature. The FREEZER is a separate compartment within the refrigerator that is used to store food and drinks that need to be kept at a very cold temperature. The CHILLER is a separate compartment within the refrigerator that is used to store food and drinks that need to be kept at a slightly cooler temperature than the FRIDGE. The ICEBOX is a separate compartment within the refrigerator that is used to store items that need to be kept frozen. Finally, an icer is a separate component of the refrigerator that is used to make ice cubes.
