A refrigerator is a machine. It is sometimes called an icebox or a fridge. People put food in it, to keep it cold or good (unspoiled) for a longer time. In general, a refrigerator can be seen as a heat pump. It takes the air from inside, and takes its heat away. The heat gets added to the air from outside. For this, it usually uses electricity.

There are also ice boxes out there that do not need electricity, and that you can take for a camping trip. You fill them with ice, and then you can keep stuff cool with them, until the ice has melted. These are often called coolers. Refrigerator-sized iceboxes were used before electricity was available.
