Patent ID: 8156999

Claim:
An indoor unit of an air conditioner, comprising: an air inlet; a plurality of fin-tube type heat exchangers each having heat transfer tubes extending through stacked plate fins; a fan; an air passage; and an air outlet, wherein the plurality of fin-tube type heat exchangers are arranged to surround the fan, and the air pressure loss of an adjacent heat exchanger disposed adjacent to the air inlet, of the fin-tube heat exchangers, is larger than the air pressure loss of a remote heat exchanger that is disposed farther from the air inlet than the adjacent heat exchanger, wherein the air inlet is provided on an upper side of the indoor unit, the adjacent heat exchanger includes an upper front heat exchanger provided in an upper front area below the air inlet and slightly tilted so as to make its upper portion positioned backward and its lower portion positioned forward, and a rear heat exchanger provided in an upper rear area below the air inlet and slightly tilted so as to make its upper portion positioned forward and its lower portion positioned backward, and the remote heat exchanger includes a lower front heat exchanger provided in a lower front area to substantially vertically extend from the upper front heat exchanger, and wherein a front panel and a rear panel are formed in the indoor unit and extend between the air inlet and the air outlet and air does not pass through the front panel and the rear panel.
