、即ち含水断熱材層が存在することによるものである。(Prior Art) It has been found that a refrigerated container that has been repeatedly used for a long period of time gradually loses its insulation performance due to aging. The main reason for this is the deterioration of the heat insulating material layer sold within the wall, ie, the presence of a water-containing heat insulating material layer.

However, due to transportation and handling operations under harsh conditions, rivets for fixing and holding the outer panels may loosen, It is not possible to prevent rainwater from penetrating into the heat insulating material layer within the wall from damaged areas due to peeling of the sealing material or damage to the outer panel due to impact or the like. For this reason, refrigerated containers that have been used for a long period of time are periodically brought to a repair shop in fixed quantities, where they are inspected for appearance and thermal insulation performance in a constant temperature room. The deterioration of the insulation material was determined, and these areas were repaired and reused.

。By the way, for refrigerated containers that fail the above insulation performance test, arbitrary parts of the outer or inner panels of the wall are stripped off, and the condition of the internal insulation layer is visually or tactually inspected, and the physical properties are analyzed. to determine the degree of deterioration of the insulation layer. Based on this determination, the degree of deterioration of the surrounding insulation material layer is also judged by analogy to determine whether or not repair is necessary. This judgment was based on past insulation performance tests of several series of repaired containers and internal investigations by dismantling the walls, FFt

This type of work was carried out at various locations on the wall where the refrigerated containers would be planted, and the walls were repaired and reused.

（実施例）
前記した如く１本発明は公知の赤外線映像装置を利用し

する。(Example) As described above, one aspect of the present invention utilizes a known infrared imaging device, and thereby requires a "thermal image" of the surface temperature distribution state of a refrigerated container, which will be explained first.
ｒ熱画像」とは物体表面から放射される赤外線エネルギ
ーを検知し、物体表面の温度分布を色調の変化（色の濃

線のエネルギーは物体の表面温度が高い程多くなる。A "thermal image" is an image that detects infrared energy emitted from an object's surface and displays the temperature distribution on the object's surface as changes in color tone (including color shading) on a screen. The energy of radiated infrared rays increases as the surface temperature of an object increases.

放射率の補正を行う必要かある。The temperature of the surface increases as the blue part in the diagram turns to red. Therefore, in the case of a refrigerated container, a red surface indicates that the cold air inside the container is not propagating to the surface, and a blue color indicates that the cold air inside the container is leaking and the surface temperature is low. show. In other words, the areas displayed in blue-based colors are determined to be areas where the insulation performance has deteriorated. However, even if objects have the same temperature, the amount of radiant energy varies depending on their material and surface condition, so when trying to find out the actual surface temperature of a refrigerated container,
Is it necessary to correct the emissivity?

Then, as shown in FIG. 2, it is assumed that portions having different tones, such as Nα1 to Nα8, appear. Therefore, we actually sampled the insulation material in the test container B corresponding to the two parts Nα1 and Nα8, performed a physical property test, adjusted the thermal conductivity, and based on the test values, we determined that the This is a method for evaluating the heat insulation performance of the portion Nα2 to Nα7.

In particular, increasing the performance of the dummy container will improve the deflection by 11 degrees.

前記２）の相対評価方法を使用するのが好ましい。3) Indirect evaluation method: This evaluation method is used when the object to be photographed by the infrared imaging device A is large and difficult to obtain a thermal image of an effective size, such as when the test container is a 40-foot container. If the dummy container D can be moved for each photographing, it is preferable to use the relative evaluation method of 2) above as much as possible.

のみの熱画像をとる（第６図ｂ）。This will be explained in more detail with reference to FIG. 5 and FIGS. 6(a) and (b). That is, for the first time, thermal images of, for example, the right half of the dummy container D and the test container B are taken under the same conditions (FIG. 6a). Next, a thermal image of only the test container was taken for the second time (Figure 6b).

After that, the left and right thermal images obtained in Figure 6 are compared to evaluate the insulation performance of the left half of the test container, and the total insulation performance of the entire test container is calculated to be 41[i]. .
（発明の効果） １）現場に於て短時間で断熱性能が判定出来る。(Effect of the invention) 1) The insulation performance can be determined on-site in a short time.

長時間を必要としていた。By photographing and analyzing the temperature distribution on the outer surface of a refrigerated container using an infrared imaging device, the insulation performance can be accurately determined in a very short time. In order to measure the thermal insulation performance in a conventional temperature-controlled room, it was necessary to transport the material to the factory, and it took a long time to take the measurements.

その程度を具体的に判別することは不可能であった。2) It is possible to specifically identify areas where the insulation performance has deteriorated. This method can display the temperature distribution on the outer surface of the refrigerated container by changing the color tone (for example, changing in 16 colors or 8 colors), so it is possible to specifically identify areas where insulation performance has deteriorated and the degree of deterioration. . Incidentally, although it is possible to determine the insulation performance of the entire refrigerated container by measuring the insulation performance in a conventional constant temperature room, it has been impossible to specifically determine the area where the insulation performance has deteriorated and its degree.
