The outdoor air introduced from the blowing fan 110 is cooled through the evaporator 130, To the inside of the vehicle. At this time, the heater 120 passes the air introduced from the blowing fan 110 at a high temperature to block the inflow of the air into the vehicle, and circulates the air through the evaporator 130 in the duct to remove moisture.

2, the blowing fan 210 of the air conditioner 200 for a vehicle is installed inside a cooling and heating duct of a vehicle, and the outside air is introduced into the vehicle according to the operation of the blowing fan 210 do.

The evaporator 220 cools the air introduced from the blowing fan 210 by heat exchange.

More specifically, the evaporator 220 cools and condenses indoor and outdoor air forcedly inhaled through the blowing fan 210 so that only air of low temperature and dryness can be delivered to the interior of the vehicle. At this time, the evaporator 220 is provided with a condensed water drain hole (not shown) in the lower part of the evaporator to discharge the condensed water generated when the air is cooled. The condensed water generated when the air conditioner is operating is discharged to the outside through the drain hole.

The heater 230 is installed to convert the air flowing into the blowing fan 210 into high temperature air and supply the air to the inside of the vehicle. That is, the air blown from the blowing fan passes through the evaporator 220 in which the operation is stopped, passes through the heater 230, and gets heat to get hot.

Here, the air heated by the heater 230 is shielded by the inflow / outflow blocking part 260 so as to prevent the inflow of moisture into the interior of the vehicle. Accordingly, the humidity of the evaporator 220 is controlled to be dried by continuously circulating the hot air through the heater 230, thereby preventing the growth of fungi and bacteria.

The blower 270 blows air supplied from the evaporator 220 or the heater 230 to the inside of the vehicle.

Here, when the operation of the air conditioner is turned off, the operation mode is switched to remove the moisture of the in-vehicle evaporator 220.

If the operation of the air conditioner of the vehicle is off, the humidity of the air conditioner is measured (S103). That is, the humidity sensor 250 installed in the evaporator 220 measures the humidity and transmits the measured humidity value to the controller 240.

Then, if the measured humidity value is higher than the predetermined humidity value, the heater 230 is operated (S104, S106).

More specifically, in the control unit 240, if the humidity value of the evaporator, which is measured to be higher than a preset humidity value, is high, the mode is switched to a mode for removing moisture to operate the heater of the vehicle.

At this time, inflow of outside air into the vehicle is blocked when the heater 230 is operated, and the air heated by the heater 230 is circulated to the evaporator 220 to remove moisture from the evaporator 220.

Then, if the operation time of the heater 230 is longer than the preset time, the heater operation is turned off (S109). That is, the controller 240 controls the operation of the heater of the vehicle on / off automatically regardless of whether there is an in-vehicle driver or not. The heater 240 calculates the heater operation time according to the moisture amount of the evaporator, The operation of the heater is turned off in consideration of the time at which the moisture is removed.

Then, the heater 230 is turned off, and the control unit 240 turns off the vehicle.

The vehicle state of each step is transmitted to the smartphone 300 of the user, and the user controls the state of the vehicle through the vehicle management smartphone application of the user.

That is, the controller 240 transmits the humidity value measured in the evaporator 220, the vehicle on / off state, and the vehicle status information to the user smartphone 300. Here, the user can grasp the state of his / her own vehicle through the application of the smart phone 300 and control the vehicle.

After the step of turning off the heater operation of the vehicle, the step of controlling the flow direction of the air so that the internal air of the vehicle is released to the outside of the vehicle when the user injects the antifungal agent is further performed. That is, when the user injects the fungicide, the controller 240 controls the air circulation direction of the blower 270 such that the air in the vehicle flows into the evaporator 220, which is the interior of the duct of the vehicle, Thereby controlling the flow. That is, the blower 270 blows the flow of air into the duct in the opposite direction when spraying the fungicide, unlike air blowing air into the vehicle during operation of the air conditioner or the heater.
