Description

  The present invention relates to a highly heat-insulating glass structure as a kind of heat exchange member.

Insulating glass used for doors and windows in freezer / refrigerators, luxury buildings, etc., was hollow glass, energized glass, and a glass surface coated with an optical semiconductor based on titanium oxide. . Heat insulation is improved compared to single-layer glass, and dew condensation performance is improved, but condensation occurs when the temperature difference becomes severe.

As an improvement measure, the transparency of the vacuum and the high thermal insulation performance are utilized, the outer layer is a nitrogen layer, and a desiccant is placed to prevent fogging of the glass surface.
Conventionally, there was a non-transparent vacuum heat insulating material. (For example, refer to Patent Document 1 and Patent Document 2) Further, there is a door glass whose surface is coated with an optical semiconductor mainly composed of titanium oxide. (For example, see Patent Document 3)

  It is the development of a structure excellent in heat insulation that can prevent dew condensation on the glass surface even in an environment of high temperature and ultra-high humidity as compared with a highly heat-insulated structure mainly composed of known glass.

  High heat insulation structure mainly composed of glass is composed mainly of vacuum glass and double-cured glass, a nitrogen gas layer is formed between the cured glass and vacuum glass, the surroundings of the glass are made airtight, and a frame is attached and integrated. High thermal insulation. The glass main body is composed of a double vacuum glass, a double-cured glass, and a total of quadruple glass. Gives resistance to assault on double-cured glass. In addition, one layer of the double-cured glass has a gentle curve and is more resistant to assault than the flat glass. The vacuum glass is doubled, and at least one layer uses low emission glass (Low-e glass). Furthermore, by placing a desiccant in the nitrogen layer between the hardened glass and the vacuum glass, a stable effect of drying and heat insulation was realized.

  The highly heat-insulating structure again improves the heat insulation and soundproofing properties of the multilayer glass by means of vacuum glass. In particular, it prevents condensation on the glass surface under high temperature and ultra-high humidity environmental conditions. This highly heat-insulating structure can be used in a wide range such as a refrigerator, a freezer, an architectural window, and a door. For example, in the area of bread making, when using a machine (dough conditioner) that can carry out the processes from freezing, refrigeration, and fermentation of dough in one unit, the internal temperature is minus 19 degrees during freezing and 45 during fermentation. Even when the relative humidity is 95%, the door does not condense on both sides, so bakers can clearly see the changes in the dough inside the door.

  The highly heat-insulating structure mainly composed of the glass of the present invention (13) is a frame (14) and a glass body (13), and the glass body (13) is a vacuum glass (4) (5) (10) and a double-cured glass. (1) Consists of (8), and the layer (1) of the double-cured glass has a gentle curve and has a stronger resistance to impact than the flat glass. Moreover, low radiation glass (Low-e glass) (4) is used for at least one of the vacuum glasses (4), (5), and (10), and the support (12) between the vacuum layers (10) can be used as much as possible. Use one with a good outlook. The hardened glass (1) (8) is placed on both sides of the vacuum glass (4), (5) and (10), a nitrogen gas layer (9) (11) is formed between the two glasses, and the periphery of the glass is latex (2) (6 ), Etc., and integrated. Including the double vacuum glass (4) (5) (10) and the double-cured glass (1) (8), the glass structure (13) is actually composed of quadruple glass. Resistant force is imparted to the entire double-cured glass (1) (8). By placing the desiccant (3) (7) in the air layer (9) (11), a stable effect of drying property and heat insulation property was realized.
