Embodiment Construction

[0037] Now, specific embodiments of the present invention will be described in detail, examples of which are shown in the accompanying drawings. Wherever possible, the same reference numbers are used throughout the figures for identical or similar parts.

[0038] Fig. 1 shows a diagram of a refrigerant valve control device of a refrigerator according to the present invention. As shown in FIG. 1 , the refrigerator includes a temperature sensing part 30 , a refrigerant valve 40 and a control part 50 . The temperature sensing part 30 senses the temperature inside the refrigerator. The refrigerant valve 40 adjusts the circulation amount of refrigerant supplied to the cooling air of the storage compartment. The control part 50 , which may be a microcomputer, controls the refrigerant valve 40 according to the temperature sensed by the temperature sensing part 30 and based on a predetermined algorithm.

[0039] The control part 50 determines whether the refrigerant valve 40 is ecc...

Abstract

The present invention relates to a refrigerant valve control device and a control method thereof, which adjusts eccentricity of a refrigerant valve during an operation of a refrigerator to prevent overcooling. A refrigerant valve control device of a refrigerator includes a temperature sensing part that senses temperature inside the refrigerator; a refrigerant valve that selectively opens and closes a refrigerant path; and a controlling part that controls the refrigerant valve based on temperature differences between the sensed temperature inside the refrigerator and a predetermined control temperature. In another aspect of the present invention, a control method of a refrigerant valve for a refrigerator includes determining whether refrigerant is leaked at a refrigerant valve based on temperature differences between the temperature inside the refrigerator and a predetermined control temperature; and controlling the refrigerant valve based on the result of the determination.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2006-0045844 filed May 22, 2006, the contents of which are incorporated by reference as if fully set forth herein. technical field [0003] The present invention relates to a refrigerator, and more particularly to a refrigerant valve control device and a control method thereof. The device adjusts the eccentricity of the refrigerant valve during operation of the refrigerator to prevent overcooling. Background technique [0004] Typically, a refrigeration device such as a refrigerator regulates temperature by using a high-temperature / high-pressure refrigerant. This specification describes a refrigerator of a refrigerating device to explain the above principles. [0005] Figure 3 shows a diagram of a refrigeration cycle with a refrigerant valve. As shown in FIG. 3 , the refrigeration cycle of a refrigerator includes a compressor 11 , a condenser 13 a...
