first embodiment

[0028]FIG. 2 is a schematic view illustrating a hybrid cooling system of a refrigerator according to an embodiment of the present invention. FIG. 3 is a sectional view illustrating a hybrid cooling structure in a refrigerator according to the present invention. FIG. 4 is a schematic view illustrating a general thermoelectric module.

[0029] As shown in FIG. 2, the refrigerator includes a refrigerant circulation type cooling system using circulation of a refrigerant to generate a cooling effect, and a thermoelectric module type cooling system using an electrical co-operation, namely, a Peltier effect.

[0030] The refrigerant circulation type cooling system includes a compressor 10 for compressing a gas refrigerant, a condenser 20 for condensing the refrigerant compressed in the compressor 10 to a liquid state, an expansion device 30 for expanding the refrigerant condensed in the condenser 20 to a fine mist state, and an evaporator 40 for heat-exchanging the expanded refrigerant with amb...

fourth embodiment

[0056]FIG. 7 is a sectional view illustrating a freezer according to a fourth embodiment of the present invention. the present invention is similar to the third embodiment, except that the thermoelectric module 50 is attached to the evaporator 40.

[0057] In this case, a fraction of air cooled by the evaporator 40 is fed to and circulates through the freezing compartment 110 by the blower 60. The remaining fraction of the cooled air is re-cooled by the thermoelectric module 50, and then circulates through the cryogenic compartment 130 by the blower 70.

[0058] In the above-illustrated embodiments, the refrigerator and freezer are configured by a combination of a refrigerant circulation type cooling system and a thermoelectric module type cooling system using a Peltier effect. Accordingly, it is possible to operate only the thermoelectric module, if necessary, to locally cool only the cryogenic compartment.

[0059] In the refrigerator and freezer using the illustrated hybrid cooling stru...

Abstract

A cooling system includes a cooling cycle which includes an evaporator for cooling air; and a thermoelectric module using a Peltier effect to provide a heat absorption portion and a heat discharge portion, the air cooled by the evaporator being further coolable by the heat absorption portion.

Description

[0001] This Nonprovisional Application claims priority under 35 U.S.C. §119(a) on Patent Application No. 10-2004-0116240 filed in Korea on Dec. 30, 2004, the entire contents of which are hereby incorporated by reference. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a hybrid cooling system, and, more particularly, to a hybrid cooling system wherein air heat-exchanged in an evaporator is re-cooled using a thermoelectric module having an electrical function to generate a cooling effect, so that the hybrid cooling system can provide a lower temperature, and a refrigerator and a freezer using the hybrid cooling system. [0004] 2. Description of the Related Art [0005] Generally, a refrigerator includes a compressor, a condenser, an expansion device, and an evaporator which form a cooling cycle to perform operations for compressing, condensing, and evaporating a refrigerant. [0006] In such a refrigerator, however, it is difficult to lo...
