2. The air conditioning system according to claim 1, wherein the duct member comprises a supply duct allowing inflow of outdoor air and an exhaust duct allowing outflow of indoor air, the supply duct and/or the exhaust duct including one or more straight tubes having a predetermined length, an elbow connected to the straight tube for changing air flow passage, an equally-shaped connector connecting the straight tubes and/or connecting the elbow to the straight tube, and a differently-shaped connector connecting the straight tube or the elbow to the ventilation unit.

3. The air conditioning system according to claim 1, wherein the air cleaning unit is connected to the duct member or a branch duct branching off from an end or side of the duct member by an installation case having a suction hole and an exhaust hole formed through a top surface thereof, when an end of the duct member or and end of the branch duct terminates through a ceiling.

4. The air conditioning system according to claim 1, wherein the air cleaning unit is connected to the duct member or a branch duct branching off from an end or side of the duct member by an installation case having a suction hole and an exhaust hole formed in a front-to-back direction thereof, when an end of the duct member or and end of the branch duct terminates through a wall.

5. The air conditioning system according to claim 1, wherein the duct member comprises an end running through a wall and a branch duct branching off from one side of the duct member and running through a ceiling, and a plurality of the air cleaning units are connected to the end of the duct member and an end of the branch duct, respectively.

6. The air conditioning system according to claim 1, wherein the air cleaning unit and the ventilation unit are installed in separate areas, respectively.

7. The air conditioning system according to claim 1, further comprising a humidifier at the duct member for controlling humidity of an air flow into an indoor area.

8. The air conditioning system according to claim 1, further comprising:

a distributing unit connected to an end of the duct member; and

at least one distinct duct member branching off from the distributing unit and connected to the air cleaning unit.

9. The air conditioning system according to claim 1, further comprising a heater or an air cooling unit at the duct member for controlling temperature of an air flow into an indoor area.

10. The air conditioning system according to claim 1, further comprising a diffuser connected to the ventilation unit or the duct member.

11. The air conditioning system according to claim 10, further comprising:

a distributing unit connected to the diffuser; and

a plurality of distinct diffusers branching off from the distributing unit.

12. An air conditioning system comprising:
