Abstract: A refrigerator may include a body formed with a storage space and a cooling module accommodating space; a cooling module disposed in the cooling module accommodating space and having a heat absorption part and a heat radiating part; a drawer supporter disposed inside the storage space; and a drawer supported by the drawer supporter, and the drawer supporter is formed with an inner passage through which cold air flowing from the heat absorption part passes, and the drawer supporter is formed with a plurality of cold air discharge ports through which cold air of the inner passage is discharged in an opposite direction. Therefore, it is possible to maximize the depth of the storage space in the front-rear direction while minimizing the number of parts, and cool the entire storage space evenly.

Abstract: A control method for a refrigerator comprises driving a first cooling fan to cool a first storage chamber; adjusting a damper to cause cold air to simultaneously flow through first and second cold-air passages; adjusting a damper to reduce the opening angle of the first cold-air passage, when the temperature of a high-temperature chamber reaches a value smaller than or equal to a second reference temperature for the high-temperature chamber; adjusting a damper to reduce the opening angle of the second cold-air passage, when the temperature of a low-temperature chamber reaches a value smaller than or equal to a second reference temperature for the low-temperature chamber; and driving a second cooling fan to cool a second storage chamber. When a predetermined time elapses or the sensed temperature of the high-temperature chamber reaches a first set temperature, the damper is adjusted to increase the opening angle of the first cold-air passage.
