Patent ID: 7997328

Claim:
An air conditioner comprising: a case having a first side, a second side, a third side opposite the first side, and a fourth side opposite the second side, the case further including a top surface and a bottom surface; an air-discharge inlet installed at the first side, the air-discharge inlet located closer to the second side than to the fourth side; an air-discharge outlet installed at the third side, the air-discharge outlet located closer to the fourth side than to the second side; an air-supply inlet installed at the third side, the air-supply inlet located closer to the second side than to the fourth side; an air-supply outlet installed at the first side, the air-supply outlet located closer to the fourth side than to the second side; an air-supply unit installed in the case and configured to flow air from the air-supply inlet to the air-supply outlet; an air-discharge unit installed in the case and configured to flow air from the air-discharge inlet to the air-discharge outlet; a centrifugal fan provided at the air-supply unit and the air-discharge unit, respectively, and configured to suck air in an axial direction thereof and discharge the air in a radial direction thereof; an air-supply scroll housing including a first suction intake and a first air-discharge portion configured to be connected to the air supply outlet; an air-discharge scroll housing including a second suction intake configured to face the first suction intake and a second air-discharge portion configured to be connected to the air discharge outlet; and first and second heat exchangers installed in the case, wherein the air-supply unit, the air-discharge unit and the two heat exchangers are arranged in such a manner that first and second air-supply passages are formed from the air-supply inlet to the air-supply outlet and first and second air-discharge passages are formed between the air-discharge inlet to the air-discharge outlet, the first air-supply passage crossing the first air-discharge passage in the first heat exchanger and the second air-supply passage crossing the second air-discharge passage in the second heat exchanger.
