Air-conditioning system

An air-conditioning system comprising:

• an indoor unit which is to be arranged in a room to be air-conditioned, said indoor unit including:
• (a) a fin-and-tube type heat exchanger that is made up of a heat-exchanging pipe, and a plurality of fins which are arranged at predetermined intervals and through which the heat-exchanging pipe extends;
• and (b) circulating means for causing the air in the room to be circulated through the heat exchanger;
• an air cleaner incorporated in the indoor unit and arranged in front of the heat exchanger, with a predetermined gap provided with reference to the heat exchanger, said air cleaner including:
• (a) an electric dust-collecting section for catching dust particles included in the air;
• and (b) an odorant filter section for eliminating odorants from the air, said electric dust-collecting section and said odorant filter section being arranged side by side in the same plane;
• and
• engaging means, projected from the air cleaner, for engaging with the heat exchanger, said engaging means including a pair of projected members located in a central portion of the air cleaner and vertically spaced apart from each other in such a manner as to opposite each other, each of said projected members including a distal end portion engageable with the heat exchanger.
