Abstract

The present invention includes: a cabinet assembly in which an internal space is formed, and a suction port is formed penetrating through the rear surface of the cabinet assembly, and indoor air is sucked through the suction port; a fan provided in the internal space assembly; and a heat exchange assembly, the heat exchange assembly is manufactured as a micro-channel type and disposed between the fan assembly and the suction port, wherein the heat exchange assembly includes: a first heat exchanger, the first heat exchanger is manufactured a micro-channel type, arranged on the lower side of the inner space (S) and vertically arranged; a second heat exchanger, which is manufactured as a micro-channel type, arranged on the upper side of the inner space (S) side, vertically disposed and stacked above the first heat exchanger; and a support disposed between the first heat exchanger and the second heat exchanger to integrally couple the first heat exchanger and the second heat exchanger and support the second heat exchanger. The refrigerant supplied to the heat exchange assembly is operated to flow into the single heat exchanger after passing through the second heat exchanger or the first heat exchanger. In the present invention, the separately manufactured microchannel type first heat exchanger and second heat exchanger may be stacked on each other in the vertical direction and thus be operated as a single heat exchanger.

Description

technical field [0001] The present invention relates to an indoor unit of an air conditioner, and more particularly, to an indoor unit of an air conditioner including a heat exchange assembly. Background technique [0002] Generally, an air conditioner includes a compressor, a condenser, an evaporator, and an expander, and uses an air conditioning cycle to supply cool or warm air to a building or room. [0003] The air conditioner is structurally divided into a split type air conditioner in which the compressor is installed outdoors, and an integrated type air conditioner in which the compressor is integrally manufactured. [0004] In the split-type air conditioner, the indoor heat exchanger is installed in the indoor unit, and the outdoor heat exchanger and the compressor are installed in the outdoor unit, and then the two separate units are connected to each other by refrigerant pipes. [0005] In the all-in-one air conditioner, the indoor heat exchanger, the outdoor heat...
