To provide a dew condensation detector for vehicles, an air conditioner for vehicles, and a dew condensation detection method for vehicles, which are capable of detecting more accurately than in prior art that an inner surface of a vehicular cabin is in a state of forming dew.SOLUTION: In a control device 200 serving as a dew condensation detector for a vehicle, an in-vehicle humidity specification part 210 specifies an in-vehicle humidity Hi that is humidity inside a vehicular cabin of a railway vehicle. An in-vehicle temperature specification part 220 specifies an in-vehicle temperature Ti that is air temperature in the vehicular cabin. An outside-vehicle temperature specification part 230 specifies an outside-vehicle temperature To that is ambient temperature outside the railway vehicle. An in-vehicle wind speed specification part 240 specifies an in-vehicle wind speed Vi that is wind speed of an air stream formed in the vehicular cabin according to air conditioning equipment for air conditioning the vehicular cabin. A dew condensation determination part 260 determines whether or not an inner surface of the vehicular cabin is in a state of forming dew, by using values of the in-vehicle humidity Hi, the in-vehicle air temperature Ti, the outside-vehicle temperature To, and the in-vehicle wind speed Vi. A determination result output part 270 outputs a determination result of the dew condensation determination part 260.SELECTED DRAWING: Figure 3

    【課題】車室の内面に結露が発生しうる状況にあることを従来よりも正確に検出することが可能な車両用結露検出装置、車両用空調装置、及び車両用結露検出方法を提供する。【解決手段】車両用結露検出装置としての制御装置200において、車内湿度特定部210は、鉄道車両の車室内の湿度である車内湿度Hiを特定する。車内温度特定部220は、車室内の気温である車内温度Tiを特定する。車外温度特定部230は、鉄道車両の外部の気温である車外温度Toを特定する。車内風速特定部240は、車室を空調する空調機器によって車室内に形成される気流の風速である車内風速Viを特定する。結露判定部260は、車内湿度Hi、車内温度Ti、車外温度To、及び車内風速Viの値を用いて、車室の内面に結露が発生しうる状況にあるか否かの判定を行う。判定結果出力部270は、結露判定部260の判定結果を出力する。【選択図】図3
