ABSTRACT:
An air conditioner for vehicles can operate at a dehumidifying-operation mode including at least a dry-cooling or a dry-heating mode. The air conditioner comprises a plurality of discharge ports including a defroster discharge port and discharge port switching dampers, a control system for opening at least the defroster discharge port for a predetermined time when the dehumidifying-operation mode is selected, and a control system for opening another discharge port determined in accordance with an operation mode and the like after the predetermined time has elapsed. When the dehumidifying operation is selected, at least the defroster discharge port is opened only for the predetermined time and temperature-conditioned air is discharged to the windshield from the defroster discharge port. After the predetermined time has elapsed, a discharge port in accordance with an operation mode is opened. Traveling safety can be increased by removing the cloud of moisture from the windshield at first in the environment of a dehumidifying operation, that is, in the environment that the humidity in the interior of the vehicle is high and the windshield is likely to be clouded up. The troublesome job of manually selecting the defroster discharge port to remove the cloud of moisture becomes unnecessary.
