In a refrigerator, heat is transferred from the cooler interior (where the food is stored) to the warmer exterior environment. This process is made possible by the refrigerator's cooling system, which uses a refrigerant and a cycle of evaporation and condensation to remove heat from the inside of the refrigerator and expel it outside, thus going against the natural direction of heat flow from hot to cold.
