ENVIRONMENTAL TEST DEVICE AND ENVIRONMENTAL TEST METHOD

PROBLEM TO BE SOLVED: To provide an environmental test method capable of suppressing useless icing, and an environmental test device.SOLUTION: With an environmental test device 1, where a heat insulation bath 3 containing a test chamber 5 for installing a test object 80, a cooling device 20 capable of decreasing temperature in the test chamber 5 to temperature below a freezing point, and a humidification device 8 for humidifying inside of the test chamber 5 are provided, the test object 80 is installed in the test chamber 5 that is adjusted to be low temperature environment below a freezing point, thereafter inside of the test chamber 5 is humidified, allowing the test object to be subjected to ice accretion. Inner wall heating means 60 for heating an inner wall of the heat insulation bath 3 is provided in the environmental test device 1.SELECTED DRAWING: Figure 1 【課題】無駄な着氷を抑制することができる環境試験方法及び環境試験装置を提供する。【解決手段】被試験物８０を設置する試験室５を含む断熱槽３と、試験室５内の温度を氷点下の温度に降下させることができる冷却装置２０と、試験室５内を加湿する加湿装置８を有し、氷点下の低温環境に調整した試験室５内に被試験物８０を設置し、その後に試験室５内を加湿して被試験物に着氷させることができる環境試験装置１であり、断熱槽３の内壁を加熱する内壁加熱手段６０を有する。【選択図】図１
