Benefits of technology

[0016] According to the present invention, the waste heat discharged from the refrigerant passed through the condenser is efficiently used during the compression process, thereby reducing the compressing work and increasing the COP.
[0017] Furthermore, since the compressing work is reduced, the electric power consumpti

Embodiment Construction

[0024] Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The invention may, however, be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the invention to those skilled in the art.

[0025]FIG. 1 is a schematic view of a cooling system of a refrigerator according to an embodiment of the present invention.

[0026] Referring to FIG. 1, a refrigerator 10 having a cooling system according to an embodiment of the present invention includes a condensing pipe along which a refrigerant passed through a condenser flows and a suction pipe along which a refrigerant introduced into the compressor flows. The condensing pipe and a suction pipe contact each other to perform the heat exchange.

Abstract

There is provided a refrigerator. The refrigerator includes a compressor for compressing a refrigerant, a condenser for heat-exchanging the compressed refrigerant with ambient air, an expansion member for expanding the heat-exchanged refrigerant, a condensing pipe interconnecting the condenser and the expansion member, a vaporizer for heat-exchanging the expanded refrigerant with a cooling air in a freezing or cooling chamber, and a suction pipe interconnecting the vaporizer and the compressor and associated with the condensing pipe to allow a heat exchange between the suction pipe and the condensing pipe.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a refrigerator, and more particularly, to a refrigerator having an improved cooling cycle that can reduce the power consumption and improve a coefficient of performance (COP) by efficiently using thermal energy wasted during a refrigerant is introduced into an expansion valve through a condenser. [0003] 2. Description of the Related Art [0004] A refrigerator is an electrical appliance for cooling or freezing food to preserve the food. [0005] Generally, the refrigerator can be classified into a top mount refrigerator in which a freezing chamber and a chilling chamber are partitioned up and down, a bottom freezer refrigerator in which a freezing chamber and a cooling chamber are partitioned down and up, a side-by-side refrigerator in which a freezing chamber and a cooling chamber are partitioned left and right. [0006] Especially, the side-by-side refrigerator has a freezing and cooling...
