Benefits of technology

[0031] a magnetic refrigeration unit including a heat exchange structure provided with endothermic and exothermic parts, a magnet device configured to apply magnetic field to either one of the endothermic part and the exothermic part, and a magnetic substance, which is shifted between the endothermic part and the exothermic part, config

Problems solved by technology

By responding to such demand, a lubricant or coefficient of performance (COP) inside the refrigerating apparatus may deteriorate.
However, such measures are said to be unsuitable for domestic and household use due to the complexity of refrigerating system and the high-cost of such apparatus.

Embodiment Construction

[0037] There will be described a hybrid magnetic refrigerator according to an embodiment of the present invention with reference to the drawings.

[0038]FIG. 1 schematically shows the hybrid magnetic refrigerator according to a first embodiment of the present invention. The hybrid magnetic refrigerator shown in this FIG. 1 comprises a combination of a vapor compression refrigeration cycle 1 and a magnetic refrigeration cycle 10. In other words, the hybrid magnetic refrigerator shown in FIG. 1 is provided with a heat exchange connection 8, which thermally connects the vapor compression refrigeration cycle 1 and the magnetic refrigeration cycle 10. An evaporator 2 in the vapor compression refrigeration cycle 1 and a high temperature side heat exchanger 11 in the magnetic refrigeration cycle 10 are thermally attached for heat exchange at this heat exchange connection 8.

[0039] As shown in FIG. 1, the vapor compression refrigeration cycle 1 comprises a compressor 3 to compress a refriger...

Abstract

A compact and highly efficient hybrid magnetic refrigerator includes a hybrid refrigerating apparatus wherein an evaporator of a vapor compression refrigeration cycle and a heat exchanger of a magnetic refrigeration cycle are thermally connected. The magnetic refrigeration cycle is provided with a magnetic refrigeration unit in which a magnetic substance dissipates and absorbs heat according to the increase and decrease of a magnetic field in order to heat and cool a refrigerant circulating in its vicinity. The heated refrigerant is cooled by the evaporator of the vapor compression refrigeration cycle and the cooled refrigerant is supplied to the heat exchanger cooling the outside air.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application is based upon and claims the benefit of priority from prior Japanese Patent Application No. 2006-095945, filed Mar. 30, 2006, the entire contents of which are incorporated herein by reference. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a compact size hybrid magnetic refrigerator. [0004] 2. Description of the Related Art [0005] Conventionally, a vapor compression refrigeration cycle has been generally utilized for a refrigerating apparatus for domestic, household and business use (refrigeration ability: around 0.1 to 1 kW). As is well known, this vapor compression refrigeration cycle is provided with a compressor to compress a refrigerant and an expansion valve to expand the refrigerant. A condenser to dissipate heat from the refrigerant and an evaporator to absorb heat in the refrigerant are arranged in the refrigerant channel between the compressor and the expan...
