A heat insulating box of a refrigerator includes a non-flammable heat-insulator particularly a vacuum heat-insulator made of a board-shape molded inorganic fiber. Therewith non-flammability of the heat insulator is ensured and a refrigerator box prevented from catching an outside caused fire is achieved, thus a refrigerator which is safe even when a flammable refrigerant is used and which is high in energy-saving is provided.
The invention claimed is: 1. A refrigerator comprising: a refrigeration cycle composed of a compressor, a condenser, a capillary tube and an evaporator linked together forming a cycle; a heat insulating box including a heat-insulator, the heat-insulator is disposed in a space between an inner box facing inward of the refrigerator and an outer box facing outward of the refrigerator, in which the space is sealed and decompressed; and a board-shape molded inorganic fiber disposed in the space as a heat insulator; and a flammable refrigerant enclosed in the...
