  • Embodiments of the present invention relate to a refrigerator.
  • the vacuum insulation panel comprises a core material made by forming, for example, glass wool as a flock of fine glass fiber into a mat shape, by putting the core material into a gas barrier container made of a laminate film comprising aluminum foil and synthetic resin, and by evacuating an interior of the gas barrier container and closing an opening.
  • the vacuum insulation panel maintains the container interior in an evacuated state.
  • the vacuum insulation panel has a low heat conductivity, in other words, high insulation properties even though thin. Accordingly, the use of the vacuum insulation panel can allow the peripheral wall of the insulation box to have high heat insulation properties.
  • a refrigerating cycle of the refrigerator necessitates a number of pipes and tubes including a condenser pipe, a capillary tube and a suction pipe.
  • the capillary tube connects between the condenser pipe and an evaporator or a cooler, and the suction pipe connects between the evaporator and a compressor.
  • the capillary tube and the suction pipe are routed in a storage space or an interior of the insulation box since the evaporator is disposed in the storage space. This reduces a substantial interior volume of the storage space, resulting in a reduction in a storage volume for food or the like.
  • an object is to provide a refrigerator which can suppress the narrowing of the storage space of the insulation box by piping.
  • a refrigerator includes an insulation box constructed by providing an insulation panel between an outer box and an inner box.
