成してある保冷室の断熱構造に関する。[Detailed Description of the Invention] [Industrial Field of Application] The present invention is a method of applying a heat insulating foam resin such as urethane foam or polystyrene to the outer surface of a wall such as a ceiling wall constituting a cold storage room such as a freezer. The present invention relates to a heat insulating structure of a cold storage room that includes a heat insulating layer.
この種の保冷室の断熱構造を構築する場合、一
般に、天井壁等の外面に断熱層を密着状態で形成
する施工方法が採られているが、この施工方法に
よる場合は次のような問題があつた。
When constructing this type of heat insulation structure for a cold storage room, a construction method is generally used in which a heat insulation layer is formed in close contact with the outside surface of the ceiling wall, etc. However, when using this construction method, the following problems arise. It was hot.
即ち、保令室と外気との温度差による断熱層の
水蒸気透過状態を考察すると、例えば、気温が30
℃の時には水蒸気圧が0.04322Kg／cm2（31.83mm
Hg）まで含むことができるけれども、20℃の時
には0.02380Kg／cm2（17.53mmHg）とずつと少なく
なる。更に、気温が−５℃になると0.0043Kg／cm2
（3.16mmHg）となり、30℃の時にくらべて約1/1
０、−20℃の時では0.00105Kg／cm2（0.77mmHg）で
約1/42となる。それ故に、保冷室と外気との大き
な温度差の境目に位置する断熱層もそれぞれ固有

結露し、この熱伝動率の高い結露水が断熱層に蓄
積され、断熱層の断熱性能が次第に低下する。 In other words, if we consider the water vapor transmission state of the insulation layer due to the temperature difference between the storage room and the outside air, for example, if the temperature is 30
At ℃, the water vapor pressure is 0.04322Kg/cm 2 (31.83mm
Hg), but at 20°C it gradually decreases to 0.02380Kg/cm 2 (17.53mmHg). Furthermore, when the temperature drops to -5℃, it is 0.0043Kg/cm 2
(3.16mmHg), which is approximately 1/1 of that at 30℃.
At 0 and -20°C, it is 0.00105Kg/cm 2 (0.77mmHg), which is about 1/42. Therefore, the insulation layers located at the boundary between the large temperature difference between the cold storage room and the outside air each have their own water vapor permeability, so water vapor is prevented from penetrating from the high temperature side of the insulation layer to the low temperature side. do not have. As a result, the water vapor that permeates through the heat insulating layer gradually condenses and forms dew as it approaches the low-temperature wall surface, and this condensed water with high thermal conductivity accumulates in the heat insulating layer, gradually reducing the heat insulating performance of the heat insulating layer.
また、このような断熱性能の低下を抑制する手

が採られているが、その防湿処理に少しでも不満
があると、上述と同様な問題を生じるため、防湿
処理に多大の手間と高度の技術を要するととも
に、施工コストが高騰する問題があつた。 In addition, as a means of suppressing such deterioration of insulation performance, a method of applying moisture-proofing treatment to the high-temperature side of the insulation layer has been adopted, but if there is even the slightest dissatisfaction with the moisture-proofing treatment, the same problem as mentioned above may occur. As a result, moisture-proofing treatment requires a great deal of effort and advanced technology, and there has been a problem in that construction costs have skyrocketed.

The purpose of the present invention is to reduce the deterioration in insulation performance caused by the accumulation of condensed water within the insulation layer through rational modification that actively utilizes the property that water vapor moves from the high temperature side to the low temperature side. The object of the present invention is to make it possible to reduce the amount of damage and to facilitate construction at the same time.

The heat insulation structure of a cold storage room according to the present invention includes a partition material provided with a permeation path that allows the sprayed heat insulating foam resin to permeate between the outer surface of the wall and the heat insulating material, and the partition material and the wall outer surface are connected to each other. A space for storing condensed water is formed in between, and a communication hole is formed in the wall to communicate the space and the cold storage room, and the functions and effects thereof are as follows. It is as follows.
保冷室と外気との温度差に起因する水蒸気圧差

積量を大巾に少なくすることができる。
Due to the water vapor pressure difference caused by the temperature difference between the cold storage room and the outside air, even if water vapor enters from the high temperature side of the insulation layer, this water vapor will pass through the partition material and cause condensation to form between the wall outer surface and the insulation material. It is possible to introduce the steam into a water storage space and cause a portion of the steam to condense within this space. Moreover, since the water vapor and condensed water in this space are guided into the cold storage chamber through the communication holes formed in the wall, there is no accumulation of condensed water within the insulation layer, or even if it does, it is much faster than before. By doing so, the accumulated amount can be greatly reduced.
その上、断熱発泡趣旨の吹付け時に、吹付けら
れた断熱発泡樹脂の一部が仕切り材の透過路を通

仕切り材を壁面に確実に固定することができる。 Moreover, when spraying for the purpose of insulation foaming, a part of the sprayed insulation foam resin passes through the permeation path of the partitioning material and goes around between the partitioning material and the outer surface of the wall.
The partition material can be reliably fixed to the wall surface by utilizing the adhesive force of the heat-insulating foamed resin that has gone around.

Therefore, by taking advantage of the property of water vapor to move from the high temperature side to the low temperature side and actively guiding this water vapor into the cold storage chamber, the deterioration in insulation performance due to the accumulation of condensed water within the insulation layer can be avoided. can be suppressed. Moreover, it is possible to suppress such a decline in insulation performance by a simple modification of just forming the spaces and communication holes as described above, and furthermore,
Since attachment to the partition material can be made unnecessary or can be done only temporarily, construction can be made easier at the same time.

制することができるのである。 Therefore, by configuring such a ceiling wall structure, water vapor can enter from the high temperature side of the heat insulating foam resin 10, that is, from above, due to the water vapor pressure caused by the temperature difference between the freezing chamber S and the outside air. Also, this water vapor can be guided into the space a through the partition material 11, and a part of the water vapor in the space a can be condensed. Moreover, even if dew condenses on the low temperature side within the heat insulating layer, this condensed water can be made to drip into the space a. Furthermore, since the water vapor and condensed water in the space a are guided into the freezer compartment S through the communication hole 12, no condensed water is accumulated in the heat insulating layer, or even if it is accumulated, the amount of accumulated water is small. Therefore, it is possible to suppress the deterioration of the heat insulation performance due to the accumulation of dew water in the heat insulation layer.

ト５に強固に固定することができるのである。 Further, since a part of the heat insulating material 10 sprayed toward the partition material 11 goes around between the partition material 11 and the keystone plate 5 through the permeation path 11a, the adhesive strength of the heat insulating material 10 that has gone around goes around. By using this, the partition material 11 can be firmly fixed to the keystone plate 5.

構成用シート９に直接断熱発泡樹脂１０を吹き
付けながらも、この断熱発泡樹脂１０の発泡に
伴うシート９の波打ちを補強材１８にて抑制す
ることができる。 In the case of this embodiment, even though the heat insulating foam resin 10 is directly sprayed onto the flexible side wall forming sheet 9, the reinforcing material 18 suppresses the waving of the sheet 9 due to the foaming of the heat insulating foam resin 10. I can do it.
尚、前記補強材１８の格子の大きさは３〜
500mmの範囲で適当に設定すればよい。 In addition, the size of the lattice of the reinforcing material 18 is 3~
Just set it appropriately within the range of 500mm.
(ハ) 断熱発泡樹脂１０としてはポリスチロール、
