ある保冷室の天井壁断熱構造に関する。[Detailed Description of the Invention] [Field of Industrial Application] The present invention is directed to attaching a heat insulating material such as urethane foam or polystyrene to the outer surface of a ceiling wall constituting a cold storage room such as a freezer by appropriate means such as spraying. Regarding the insulation structure of the ceiling wall of a cold storage room.
この種の保冷室の天井壁断熱構造を構築する場
合、一般に、天井壁の外面に断熱材を密着状態で
付設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 ceiling wall insulation structure for a cold storage room, a construction method is generally adopted in which the insulation material is attached tightly to the outside surface of the ceiling wall, but this construction method causes the following problems. It was hot.
即ち、保冷室と外気との温度差による断熱材の

材に蓄積され、断熱材の断熱性能が次第に低下す
る。 In other words, when considering the water vapor transmission state of the insulation material due to the temperature difference between the cold 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 about 1/1 compared to that at 30℃.
10. At -20℃, it is 0.00105Kg/cm 2 (0.77mmHg), which is about 1/42. Therefore, the insulation material located at the boundary between the large temperature difference between the cold storage room and the outside air also has its own water vapor permeability, so water vapor is prevented from penetrating from the high temperature side of the insulation material to the low temperature side. do not have. As a result, the water vapor that permeates through the insulation material gradually condenses and condenses as it approaches the low-temperature ceiling wall surface, and this condensed water with high thermal conductivity accumulates on the insulation material, gradually reducing the insulation performance of the insulation material. .
また、このような断熱性能の低下を抑制する手
段として、断熱材の高温側に防湿処理を施す方法
が採られているが、その防湿処理に少しでも不備
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 to suppress such a decline in insulation performance, a method of applying moisture-proofing treatment to the high-temperature side of the insulation material has been adopted, but if there is even the slightest defect in 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.
本発明の目的は、水蒸気が高温側から低温側に
移動する性質を積極的に利用した合理的な改造を

うにする点にある。
The purpose of the present invention is to reduce the deterioration in insulation performance caused by the accumulation of condensed water within the insulation material by making a rational modification that actively utilizes the property that water vapor moves from the high temperature side to the low temperature side. The point is to be able to suppress it.

The characteristic configuration of the ceiling wall insulation structure of the cold storage room according to the present invention is that a moisture-permeable partition material is interposed between the upper surface of the ceiling wall and the heat insulating material to form a gap between the upper surface of the ceiling wall and the upper surface of the ceiling wall, and A communication hole is formed in the ceiling wall to communicate the gap and the cold storage room, and its functions and effects are as follows.
保冷室と外気との温度差に起因する水蒸気圧差

Even if water vapor enters from the high-temperature side of the insulation material due to the water vapor pressure difference caused by the temperature difference between the cold storage room and the outside air, this water vapor will pass through the partition material to the gap formed between the ceiling wall surface and the insulation material. A portion of the vapor can be condensed within this gap.
Moreover, even if dew condenses on the low temperature side within the heat insulating material, this condensed water can be allowed to drip into the gap. Furthermore, since the water vapor and condensed water in the gap are guided into the cold storage chamber through the communication holes formed in the ceiling wall, there is no accumulation of condensed water in the insulation material, or even if it does, it is much lower than before. The accumulated amount can be greatly reduced.
従つて、水蒸気が高温側から低温側に移動する
性質を利用して、この水蒸気を保冷室内に積極的

Therefore, by taking advantage of the property that water vapor moves from the high temperature side to the low temperature side, it is only necessary to form the gaps and communication holes as described above to actively guide this water vapor into the cold storage chamber, making construction easy. It has now become possible to suppress the deterioration in insulation performance caused by the accumulation of dew water within the insulation material, while also reducing the risk of deterioration.
