As shown in FIG. 8, the control unit installed in the air conditioner of the present invention determines whether the operation mode is selected once (S103), and when the selected mode is the heating and cooling alone operation mode, the air-conditioning intake opening / closing door is opened. At the same time to open the heating and cooling intake to close the air cleaning intake by the air intake opening and closing door for air so that the intake air only communicates with the heating and cooling intake (S104).

Then, the compressor is operated to allow the refrigerant to be compressed (S105), and by operating the blower fan of the indoor unit and the blower fan of the outdoor unit, heat exchange occurs in the indoor unit and the outdoor unit (S106).

In addition, when the selected mode is the air-cleaning alone operation mode, by closing the air-conditioning intake and opening the air-cleaning intake so that the air can be sucked only into the air-cleaning intake (S107).

Then, the compressor is not operated (S108), and the blower fan of the indoor unit is operated and the blower fan of the outdoor unit is not operated (S109), so that heat exchange does not occur in the indoor unit and the outdoor unit, thereby pure air cleaning function only. Do it.

Finally, when operating in the simultaneous heating and cooling operation mode, the air-conditioning inlet and the air-cleaning inlet opening step (S110), the compressor is operated to compress the refrigerant required for heat exchange (S111). ).

In addition, by operating the blower fan of the indoor unit and the blower fan of the outdoor unit to cause the heat exchange of the suction air inside the indoor unit and the outdoor unit, it is possible to bring the air cleaning effect and air conditioning effect at the same time (S112).

In addition, by determining whether there is a change in the operation mode while operating according to each of the operation modes (S113), the operation is performed according to the changed mode, or if the mode is not changed, the operation is performed in the preset mode.

Then, it is determined whether the operation end is selected (S114), and thus can end the operation or continue to proceed accordingly.

According to the present invention as described above, in the case of performing the air cleaning function, the inlet port for this function is formed separately, the intake of the air is made by the blower fan used when the cooling and heating function, the intake or discharge amount of the air heating and cooling function Since it is almost the same as the amount of air when doing this has the advantage that the capacity is significantly double compared to the existing air cleaning capacity.

Therefore, there is no significant difference between the indoor area where air conditioning and heating are performed and the indoor area where air cleaning is performed.

In addition, in the air cleaning function, since the intake of air is generated only in a separate inlet provided for air cleaning and is discharged to the outside through the air cleaning filter, the cleanliness of the air having undergone this process is better than that of the existing air conditioner. It also has the advantage of being.
