Abstract:
A vacuum insulation panel includes a core material, a first sheathing material disposed outside the core material, and a second sheathing material having different thermal conductivity from the first sheathing material, the second sheathing material being coupled to the first sheathing material to form a space to receive the core material.
Abstract:
Disclosed are a vacuum insulation material having a structure from which a folding process can be removed, a vacuum insulation material manufacturing method, and a refrigerator including the vacuum insulation material. The vacuum insulation material comprises: a core material; a first outer cover material disposed at the outside of the core material; a second outer cover material coupled to the first outer cover material so as to form an accommodation space in which the compressed core material is accommodated; and coupling parts provided at edges of the first outer cover material and the second outer cover material, wherein the length of the coupling part is 10-30 mm.
Abstract:
Disclosed are a vacuum insulating material having an improved structure as to enhance insulation and durability and a refrigerator having the same. The vacuum insulating material includes a core material, a first envelope disposed at an outer side of the core material, a blocking layer disposed between the core material and the first envelope, and a second envelope coupling to the first envelope to form an accommodating space in which the core material and the blocking layer are accommodated, wherein the blocking layer is welded or adhered to the first envelope to form an integral unit with the first envelope.
Abstract:
A thermal insulation performance measurement apparatus which measures thermal insulation performance of a thermal insulator by heat flux to the thermal insulator, measured by a heat flux sensor, and a measurement method using the same includes a heat flux sensor provided with one surface adapted to contact an object to be measured, a first heat source arranged on the upper surface of the heat flux sensor to supply heat to the heat flux sensor, a thermal insulator arranged on the upper surface of the first heat source, a third heat source arranged on the upper surface of the thermal insulator, and a second heat source arranged around the heat flux sensor.
