Title: INDOOR UNIT FOR AIR CONDITIONER
Abstract:
The present invention improves the cleanliness of conditioned air that is blown out from an indoor unit of an air conditioner comprising a dust collection filter, and also suppresses an increase in the size of the indoor unit. A dust collection filter (35) has an initial capture rate of 70% or more for particles having a diameter of 2.0 μm, as measured at a rated air volume of 25 m3/min using 11 types of JIS Z8901 Test Powder 1 based on JIS B9908 Test Method Form 2, and/or the thickness (D1) in a direction along the air flow is 10 mm or more. Air that flows from a suction port (41) to a blowout port (42) flows through an indoor heat exchanger (31), indoor fans (32, 33), and a dust collection filter (35) in that order. The indoor fans (32, 33) are disposed above or below the indoor heat exchanger (31). The dust collection filter (35) is disposed such that a vertical direction position (35a) of at least a portion of the dust collection filter (35) is the same as a vertical direction position (52a) of a blowout opening (52) of a blade accommodation chamber (RM2) of a casing (40) that accommodates blades (32a, 33a) of the indoor fans (32, 33).
