An indoor unit of an air-conditioning apparatus includes: a housing having an air inlet suctioning indoor air, an air outlet blowing out the air suctioned from the air inlet, an accommodation space connected to the air outlet and accommodating an electric component box, a wind up-down direction plate provided to the housing to cover the air outlet and the accommodation space, configured to adjust a direction of air blown out from the air outlet, and including a wind guide surface that guides the air blown out from the air outlet; and a wind shielding portion that obstructs the air blown out from the air outlet, the wind shielding portion being provided at an edge portion of a portion of the wind guide surface, the portion facing the accommodation space, the edge portion being disposed close to a rear side of the housing.

Indoor unit of air-conditioning apparatus

An air-conditioning apparatus includes a refrigerant circuit in which refrigerant is circulated, and an indoor unit configured to accommodate a load-side heat exchanger of the refrigerant circuit. The indoor unit includes an air outlet provided in the housing, an air inlet provided in the housing below the air outlet, an air passage that extends between the air inlet and the air outlet via the load-side heat exchanger, a refrigerant detection unit disposed below the air inlet, and a first partition plate configured to separate the air passage from a space in which the refrigerant detection unit is installed.

Air-conditioning apparatus

An indoor unit of an air-conditioning apparatus includes: a casing; a drain pan, which is provided inside the casing, and is configured to receive condensate water generated in the load-side heat exchanger; and a refrigerant detection unit provided below the drain pan inside the casing. The refrigerant detection unit includes: a sensor configured to detect leakage of the refrigerant; and a sensor cover configured to cover the sensor from a front surface side of the sensor. The sensor cover includes: a roof portion arranged above the sensor; and a side surface portion arranged on the front surface side or a side surface side of the sensor below the roof portion. The roof portion has an eaves portion projecting outward with respect to the side surface portion, and the side surface portion has at least one first opening port configured to introduce air to an inside of the sensor cover therethrough.
