DEW CONDENSATION DETECTOR FOR VEHICLE, AIR CONDITIONER FOR VEHICLE, AND DEW CONDENSATION DETECTION METHOD FOR VEHICLE

Japanese Patent JP2022038655

A

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
