Abstract

The present invention prevents a decrease in heat exchange efficiency. An indoor heat exchanger (22) housed in a casing (10) has: a front-surface heat exchanger (22a) disposed in a manner so as to face the back surface of a front-surface panel (4); and a back-surface heat exchanger (22b) that tilts upward with proximity to the back surface from the vicinity of the bottom end of the front-surface heat exchanger (22a). An upper filter (16a) and a lower filter (16b) are provided to a duct reaching the front-surface heat exchanger (22a) from a main intake port (10a) provided to the front of the bottom end of the casing (10). Also, at least a portion of the section of the bottom filter (16b) further downwards than is the front-surface heat exchanger (22a) is bowed forwards as a bulge.

Description

Technical field [0001] The present invention relates to a floor-standing indoor unit having a substantially V-shaped heat exchanger having a front heat exchanger and a back heat exchanger. Background technique [0002] As a conventional floor-standing indoor unit, there is known a floor-standing indoor unit that sucks air in the vicinity of the floor from an inlet provided in front of the lower end of the housing and blows it out from a blower outlet provided at the upper end of the housing ( For example, refer to Patent Document 1). The air sucked in from the suction port is supplied to the heat exchanger housed in the housing, and is heated by heat exchange with the refrigerant flowing in the heat exchanger. In addition, the heated air is blown out from the blower outlet.
