Abstract: PROBLEM TO BE SOLVED: To aim at the elevation of volume within a refrigerator, the elevation of reliability, or energy saving, concerning a refrigerator. SOLUTION: The volume in a refrigerator can be elevated by applying vacuum heat insulating material, where a sheet-form inorganic fiber aggregate is used for the core, to a refrigerator which has a plurality of evaporators. The energy saving by the suppression of temperature rise within a refrigerator and the reliability elevation by the suppression of malfunction of a control board can be contrived, by insulating heat between a compressor and the interior of the refrigerator, between a control board and the interior of the refrigerator, between a compressor and a control board, or between an evaporator and the control board, using the said vacuum heat-insulating material.

Abstract: PROBLEM TO BE SOLVED: To improve heat insulating performance or to make a heat insulating material compact, regarding a vacuum heat insulating material usable for a heat insulating container for transportation to be used for carrying chemicals and medical supplies. SOLUTION: This material is a vacuum heat insulating material having a structure easy to be bent to one side surface of a core material by making the width of an outer covering material peripheral edge part in which films of the outer covering material contact each other longer than the half of thickness of the core material. Or, the material is the vacuum heat insulating material reducing the peripheral edge part in which the films of the outer covering material contact each other by stipulating each of peripheral length and thickness of the outer covering material made of a bag material of a gusset type and peripheral length and thickness of the core material so as to be almost the same.

Abstract: PROBLEM TO BE SOLVED: To recycle the hard urethane foam, and reduce weight of a powdered vacuum heat insulating material and the scattering of the coarse particulate, by using a mixture of the urethane foam powder and a fiber material as a core material. SOLUTION: A vacuum heat insulating material 1 comprises, for example, a core material 2, a nonwoven fabric 3 having the air permeability, and a covering material 4 formed of a plastic laminate film. The core material 2 is prepared by adding the wet silica powder into the powder obtained by grinding the hard urethane foam for the surface reforming, and then adding and mixing a fiber material. Then the core material is filled in the nonwoven fabric 3 having the air permeability, and then dried, and further it is filled in the covering material, and evacuated under the reduced pressure to obtain the vacuum heat insulating material 1. In the vacuum heat insulating material manufactured as mentioned in the above, the hard urethane foam can be recycled, whereby the recycling of the heat insulating material used in a refrigerator becomes possible. Further the used paper mixed in the fiber material acts as a binder, so that the scattering of the coarse particulate can be reduced.

Abstract: PROBLEM TO BE SOLVED: To obtain an inexpensive, lightweight vacuum heat insulating body, in which a powder is not scattered when the body is broken up so that a refrigerator can be disposed of efficiently and a house can be effectively heat insulated and constructed by a method wherein the powder material of the body contains at least a hard urethane foam powder and powder aggregates are formed by heating and dehydrating the powder. SOLUTION: The vacuum heat insulating body 1 comprises an outer cover material 3 loaded with a core material 2 composed of a powder material, in which the material 3 is made up of plastic laminate films including metal foils or metal evaporation layers. And the material 2 is composed of a hard urethane foam powder, which is prepared by crushing an expanded material including air bubbles to form the powder into complex needle-like structures comprising air-bubble skeleton and air bubble films. And since adjoining powders interfere with one another, the insulating body has low density and can be dried by heat and at the same time, the powder aggregates are formed by being joinded.

Abstract: PROBLEM TO BE SOLVED: To suppress worsening of heat conductivity with the lapse of time by applying a plastic film formed of ethylene-vinyl alcohol copolymer resin with A1 evaporation applied to one side, to a gas barrier layer, and providing the Al evaporated face on the heat welded layer side. SOLUTION: Polyethylene terephthalate resin is used for an outermost layer, and an ethylene-vinyl alcohol copolymer resin with A1 evaporation applied is used for a gas barrier layer 5. An A1 evaporated layer is provided on the heat welded layer 6 side, and high density polyethylene resin is used for the heat welded layer 6. Accordingly, even in the case moisture absorbed in the ethylene-vinyl alcohol copolymer resin is desorbed in an vacuum atmosphere, the permeation of moisture is suppressed by A1 evaporation. This results in preventing worsening of heat conductivity of a vacuum heat insulating body caused by the increase of heat conductivity by gas due to degradation of vacuum generated by the influence of moisture.

Abstract: PURPOSE: To increase the viscous flow in a laminate layer so as to remove gas molecules in core members, and to obtain a desired vacuum degree in a short time, by laminating the core members vertically to the heat transmitting direction, in a vacuum adiabator in which core members consisting of a foaming plastics with a continuous foamy structure are filled in an outerjacketing member. CONSTITUTION: In a vacuum adiabator 1, core members 2 which consist of a foaming plastics having a contineous foamy structure are filled in an outerjacketing member 3. In this case, the core members 2 are laminated vertically to the heat transmitting direction. And between the laminated core members 2, metal layers having the thickness 500×10-5μm to 1000×10-5μm may be provided. Furthermore, when the vacuum adiabator 1 is manufactured, a process to leave a part of the core members 2, and to cut it vertically to the heat transmitting direction is provided, at least as a manufacture process of the core members 2. Consequently, a viscous flow in the laminate layer is increased, and gas molecules in the core members are removed by this viscous force, and a desired vacuum degree is obtained in a short time.
