A heat-exchanger fixing plate fixes a side portion of a heat exchanger to a housing panel of an air-conditioning apparatus, the heat exchanger including a heat radiation fin and a heat transfer tube. The heat-exchanger fixing plate includes a heat-exchanger support portion facing the side portion of the heat exchanger, and having an insertion hole through which a hairpin portion of the heat transfer tube of the heat exchanger is inserted; and a housing-panel fixing portion separate from and fitted to the heat-exchanger support portion fastened with a screw to the housing panel such that the heat exchanger is fixed to the housing panel. The housing-panel fixing portion is made of material having a higher mechanical strength than that of the heat-exchanger support portion, and the heat-exchanger support portion is made of the material having a lower friction coefficient than that of the housing-panel fixing portion.

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.

Indoor unit of air-conditioning apparatus

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.
