  • Patent number: 11592192
    Abstract: An indoor unit of an air-conditioning apparatus includes a heat-medium heat exchanger, an air vent valve, a drain pan, and a hose. The heat-medium heat exchanger is provided in a housing to cause heat exchange to be performed between a heat medium and indoor air. The air vent valve allows air to escape from a heat medium passage that allows the heat medium to flow in the heat-medium heat exchanger. The drain pan is provided below the heat-medium heat exchanger to receive condensation water generated at a surface of the heat-medium heat exchanger. The hose has flexibility, and is attached to the air vent valve, and provided to let out the air along with the heat medium from the heat medium passage to the inner space in the drain pan. The hose has a double-wall structure and an upper end portion of the hose is fixed to the air vent valve.
