A refrigerator having an air curtain of a temperature changing room is provided to interrupt inflow of external air into the temperature changing room when a door of the temperature changing room is opened, to realize efficient cooling, and use a separated containing space to keep food in cold storage and freezing storage in accordance with selection of a user. A refrigerator main body(100) has a freezing compartment(200) and a refrigerating compartment(300) for storing food, and a temperature changing room(400) separated from the freezing compartment and the refrigerating compartment to store food. A first cooling part(420) is installed at a rear of the temperature changing room, separated from an evaporator(220) supplying cold air to the freezing compartment and the refrigerating compartment, and supplies cold air to the temperature changing room to control a temperature to a level set by a user. A changing room cold air duct has a cold air inflow hole(120) to draw in cold air supplied from the first cooling unit to the temperature changing room. An air curtain unit is installed between the temperature changing room and a door of the temperature changing room to form an air curtain at a front of the temperature changing room in accordance with opening of the door of the temperature changing room. A temperature controller outputs an operation control signal for the first cooling unit to control a temperature of the temperature changing room to the level set by the user, and outputs an operation control signal for the air curtain unit in accordance with opening of the temperature changing room. |
