PURPOSE: A heat exchanger having a humidifier is provided to adjust humidity in a vehicle by controlling a humidifier on a duct through a damper depending on humidity. CONSTITUTION: An inlet is formed on a side of a duct(1) to flow external air. The inlet is opened or closed by a valve member(3). An evaporator(4), a blower(5) and a heater(6) are mounted on the duct, and a discharge port(7) is formed between the evaporator and the heater. The discharge port is controlled by a damper(8). When the evaporator is operated and external air is supplied to the blower, cold air is generated from the evaporator. The cold air is supplied into a vehicle through the discharge port. The damper opens the discharge port and closes the heater to air-condition the vehicle. If inside of the vehicle is dry, a controller turns on an operating valve and a humidification damper(10). Water in a water tank(12) of the humidifier is supplied to a suction sponge. The water of the sponge is supplied to the humidification damper, and blower air is fed to the damper. Therefore, the water adjusts the humidity in the vehicle. |
