Patent ID: 8104301

Claim:
A refrigerant valve control device of a refrigerator comprising: a temperature sensing part that senses a temperature inside a compartment of the refrigerator; a refrigerant path; a refrigerant valve that selectively opens and closes the refrigerant path; and a controlling part that controls the refrigerant valve based on a temperature difference value between the sensed temperature inside the compartment of the refrigerator and a predetermined control temperature, wherein the controlling part initializes the refrigerant valve if the temperature difference value is smaller than a predetermined standard value, wherein the refrigerant valve comprises a damper that opens and closes the refrigerant path, wherein the controlling part initializes a rotational movement in the position of the damper if the temperature difference value is smaller than the predetermined standard value, wherein a refrigerant path opening/closing state of the damper is initialized to allow the temperature inside the compartment of the refrigerator to rise so that the temperature difference value is greater than the predetermined standard value, and wherein the rotational movement of the damper is initiated to adjust eccentricity of the damper in order to prevent refrigerant leakage.
