Electric vehicles, which do not have a sufficient waste heat source inside, suffer from a problem wherein mileage is shortened if power from a battery is used for antifogging of windows and heating the interior of the vehicle. To solve this problem, a desiccant humidity control technique is used. During running of an electric vehicle, moisture emitted from passengers is absorbed, so as to suppress rising of an absolute humidity, by a desiccant (2) which absorbs moisture in air or discharges moisture into air by the difference in relative humidity to air, and air with a high temperature is generated by utilization of heat generated by moisture absorption. This air is sprayed to a front window and other areas so as to cause defogging as well as heat the interior of the vehicle. Further, during stopping, an electric heater (3) and a fan (4) are driven by commercial power so as to generate air with a high temperature and a low relative humidity and to regenerate the desiccant (2). In this way, since the desiccant (2) is regenerated during stopping, the configuration of the desiccant is not restricted, and a device to switch a passing-air flow passage is simplified. As a result, the antifogging air conditioning system can be made compact and can reduce the use of electricity in electric vehicles during running, whereby mileage can be prolonged, and the required capacity of the battery can be reduced. |
