Abstract: A first heat exchanger, a desiccant block, and a second heat exchanger are arranged in series. In a dehumidifying operation, a first operation mode and a second operation mode are alternately repeated. In the first operation mode, the first heat exchanger is operated as a condensor or a radiator and the second heat exchanger is operated as an evaporator. In the second operation mode, the first heat exchanger is operated as the evaporator and the second heat exchanger is operated as the condensor or radiator. A pressure reducing amount in the first operation mode is controlled to be smaller than in the second operation mode so that a degree of superheat in the evaporator (second heat exchanger in the first operation mode, first heat exchanger in the second operation mode) in each of the first operation mode and the second operation mode is appropriately controlled to increase a dehumidifying amount.

Abstract: A controller of an air-conditioning apparatus includes an operation control unit that controls operation of a compressor of a heat source unit based on target indoor temperatures of rooms, an unoccupied room detecting unit that detects an unoccupied room where no person is present among the rooms, and a correction amount setting unit that sets a temperature correction amount for correcting the target indoor temperature in a room controller of the unoccupied room detected by the unoccupied room detecting unit to reduce an air conditioning load for the unoccupied room. After the target indoor temperature is corrected by using the temperature correction amount in the room controller, when the operation capacity of the compressor controlled by the operation control unit is smaller than or equal to a preset operation capacity, the correction amount setting unit resets the temperature correction amount to be decreased by an adjustment amount.

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: An air-conditioning apparatus includes a heat source side unit including a compressor, a load side unit including a load side heat exchanger, a fan provided in the load side unit, an air direction adjuster that is provided in the load side unit and that adjusts an air direction, and a controller that controls the compressor, the fan, and the air direction adjuster. The controller determines whether an air-conditioned space is being ventilated and executes, in a case where the air-conditioned space is being ventilated, a fixed-swing mode in which a swing operation in which the air direction is changed over time by controlling the air direction adjuster is forcefully performed. At a time when the fixed-swing mode is to be entered, the controller activates the compressor when the compressor is stopped and continues operation of the compressor when the compressor is operating.
