Abstract: An air-sending device includes a fan configured to blow air into a space, an airflow direction adjusting unit configured to adjust an airflow direction of the air blown out from the fan, and a controller configured to control the fan and the airflow direction adjusting unit. The controller is configured to, when a predetermined condition is met, execute a forced swing mode regardless of a setting made by a user for the airflow direction. In the forced swing mode, a swing operation is forcibly performed in which the airflow direction adjusting unit is controlled to change the airflow direction over time.

Abstract: The indoor unit has an air passage formed therein to allow the indoor air drawn in the indoor unit to pass therethrough. The first indoor heat exchanger, the adsorption and desorption device, and the second indoor heat exchanger are arranged in the air passage. The second indoor heat exchanger is disposed downstream of the first indoor heat exchanger, and the adsorption and desorption device is disposed downstream of the first indoor heat exchanger and upstream of the second indoor heat exchanger. To perform dehumidifying control, the controller controls the opening degree of the first expansion valve and the second expansion valve to enable switching between cooling adsorption mode where the adsorption and desorption device adsorbs moisture in the indoor air and cooling desorption mode where the adsorption and desorption device desorbs the adsorbed moisture.

Abstract: An air-conditioning apparatus includes; a first heat source device configured to transfer heat to process air using as a heat source a vapor-compression refrigeration cycle; a second heat source device configured to transfer heat to the process air using an other heat source different from the vapor-compression refrigeration cycle; and a controller configured to control the first heat source device and the second heat source device. The controller deactivates the first heat source device and activates the second heat source device when, during a period in which the first heat source device is being operated to heat the process air, a temperature of the heated process air is kept at a target temperature and a parameter indicating an energy consumption of the first heat source device exceeds a first threshold value.

Abstract: A stator core for a rotating electrical machine includes an annular yoke portion; a tooth group fitted to an inner side of the yoke portion and formed such that both ends in a circumferential direction on an inner circumferential side of adjacent teeth are integrally connected with each other by a thin connection portion; and a slot for accommodating a stator winding. The yoke portion has grooves at regular intervals in an inner circumferential surface thereof and extending in an axial direction of the stator, the grooves each having a V shape such that a cross section thereof perpendicular to the axial direction opens toward an inner side of the stator core. Each tooth has, at an outer-circumferential-side end thereof, a fitting portion whose cross section perpendicular to the axial direction is formed in a wedge shape so as to allow the tooth to be fitted along the corresponding groove.
