초록

An insulation box unit and a refrigerator of the present invention employs i) rigid urethane foam with a 8.0 MPa-or-greater bending modulus, and a 60 kg/m3-or-lower density, and ii) a vacuum insulation material. The proper bending modulus provides the insulation box unit with a substantial strength, even in the case that the coverage of the vacuum insulation material with respect to the surface of the outer box exceeds 40%. The proper density prevents the insulation box unit from poor insulation efficiency due to undesired solid thermal conductivity. D...
