Abstract: An indoor unit of an air-conditioning apparatus includes: a heat exchanger which generates conditioned air by carrying out heat exchange between refrigerant and indoor air; and a drain pan disposed below a lower end of the heat exchanger to correct dew condensation water. The drain pan includes at a side portion thereof: a side dew receiving portion which receives dew condensation water; and a recessed portion disposed below the side dew receiving portion, the recessed portion being recessed toward an other side portion opposite to the side portion. A side face of the drain pan is provided with a heat insulating sheet covering an entire opening of the recessed portion.

Abstract: An indoor unit of an air-conditioning apparatus includes a base forming a rear surface and a part of a top surface of a main body and a design panel removably attached to at least one of a left side and a right side of the base to form a part of the top surface, a part of a lower surface, and a side surface of the main body. The base includes a first corner portion connecting a top surface and a side surface of the base and a lower surface and the side surface of the base and a step portion formed on at least one of the top surface and the lower surface of the base. The design panel includes a second corner portion connecting a top surface and a side surface of the design panel and a lower surface and the side surface of the design panel.

Abstract: A communication-adapter mounting device is used for mounting a communication adapter that relays communication between an air-conditioning apparatus and another apparatus. The communication-adapter mounting device includes a body into which the communication adapter is to be accommodated and from which the communication adapter is allowed to be removed, and a clip to mount the body to a housing of the air-conditioning apparatus. A mounting plate of the body includes a mounting hole for securing the communication-adapter mounting device to an installation location in which to install the communication adapter. Further, the body has a clip holding mechanism to hold the clip and to allow the clip to be removed.
