A refrigerator is provided which includes a variable temperature storage formed in the chilling chamber; a heating room formed on a side of the variable temperature storage; a heating device installed in the heating room and configured to generate heat; a first local circulating path in which cool air in the freezing chamber flows into a rear path through the variable temperature storage; an adjusting device configured to adjust a quantity of cool air flowing into/out of the variable temperature storage through the first local circulating path; a second local circulating path in which heated air in the heating room passes the variable temperature storage and flows into the heating room again; and a temperature sensor configured to sense a temperature in the variable temperature storage. Because various ranges of temperature can be maintained in the refrigerator, it is possible to perform optimum-temperature storing according to various kinds of foods. Accordingly, various kinds of foods can be stored freshly for a longer time.
