Therefore, the air, which forcibly flows by the fan 102, can minimize the flow resistance occurring while passing through the discharge grill 11.
  • the air which passes through a point adjacent to the central part 111, flows in a direction that forms a relatively smallest angle to the rotating orbit of the fan 102.
  • the discharge grill 11 of the outdoor unit 1 since the ends of the second grill part 113 adjacent to the central part 111 are connected in a state that forms a relatively smallest angle based on the rotating orbit of the fan 102, the flow resistance of air passing through the discharge grill 11 can be more minimized.
