Abstract: An air-conditioning apparatus according to an embodiment of the present invention includes: a heating device configured to perform a heating operation by heating air inside a room and sending out the heated air; a floor temperature sensor configured to measure a floor temperature inside the room; a suction air temperature sensor configured to measure a suction air temperature that is a temperature of the air flowing into the heating device; and a controller configured to calculate a reference temperature from the floor temperature and the suction air temperature, and when determining that the reference temperature is lower than a start determination temperature designated in advance, cause the heating device to perform the heating operation.

Abstract: An air-conditioning apparatus includes an indoor unit including a pair of lateral air-directing vanes each configured to adjust an orientation of an air flow blown from an air outlet in a lateral direction, and a remote control device configured to receive selection of at least two of a plurality of air flow directions in the lateral direction. The indoor unit includes an indoor-unit controller configured to individually adjust operations of the pair of lateral air-directing vanes in accordance with the selection of the plurality of air flow directions in the remote control device such that a left partial air flow does not collide with a right partial air flow.

Abstract: In an indoor unit for an air-conditioning apparatus, a casing has an air inlet formed in an upper part and an air outlet formed below a front part. The casing accommodates a heat exchanger and fan. A horizontal airflow-direction louver is mounted pivotally inside the air outlet to guide airflow in a horizontally changeable manner. A vertical airflow-direction louver is mounted to cover the air outlet in a closed position and to guide airflow in a vertically changeable manner. An infrared sensor projects downward from the casing at a position in a horizontal end portion of the casing and in front of the air outlet. An airflow blocking portion is located behind the infrared sensor, and has a side wall on or beside one edge of the air outlet. The side wall is located closer to a center of the air outlet in the horizontal direction than the infrared sensor.
