An air conditioner, a control method and a computer-readable storage medium are provided. The air conditioner has a body provided with an air outlet. An air output assembly suitable for adjusting an air output angle of the air outlet is arranged at the air outlet. The air conditioner further has a detection device for acquiring position information of a target and a controller electrically connected to the air output assembly and the detection device for controlling the air output assembly according to the position information.

An air conditioner, a control method for an air conditioner, and a computer-readable storage medium are provided. The air conditioner has a body, an air outlet, and an air output assembly for adjusting the air output of the air outlet. The air conditioner further has a detection device and a controller. The detection device acquires a distance value of a target object from the air conditioner. The controller is electrically connected to the air output assembly and the detection device, and controls the air output assembly to switch among different operative configurations based on the distance value.

A thermostat of an HVAC system receives active event parameters from a utility provider. The active event parameters include a start time, a stop time, and a predefined temperature setpoint for the active event, which is associated with a requirement to decrease energy consumption between the start time and the stop time. Following the start time, the thermostat adjusts a setpoint temperature of the HVAC system to the predefined setpoint temperature.

A plurality of thermal areas (11a, 11b, 11c, and 11d) of different thermal environments are formed in a room (11). When it is determined that a person (13) riding on a movable object (20) is feeling uncomfortable in the thermal area (11d), the movable object (20) is remotely operated to move toward the thermal area (11a) where the person (13) feels comfortable.

A heating control device includes an estimating unit to estimate a latent heat load of air present in a ventilation target space as a ventilation target and a heating control unit to control, in accordance with the latent heat load estimated by the estimating unit, a temperature of heating outside air by a heat exchanger to heat outside air supplied to the ventilation target space, via control of a condensation temperature of a refrigerant in the heat exchanger. The estimating unit estimates the latent heat load from ΔX, which is a value obtained by subtracting, from a target absolute humidity (X0) set by a temperature/humidity setting device to set a target humidity of an interior as the ventilation target space, an absolute humidity (Xi) of the interior detected by an indoor humidity sensor.

An air conditioner and a method for operating an air conditioner are provided. The air conditioner may include a case having a space formed therein and an open bottom; a panel disposed under the case and having an inlet and a plurality of outlets disposed around a circumference of the inlet; a fan disposed in the case and configured to generate an airflow from the inlet to the plurality of outlets; an airflow direction controller disposed at the plurality of outlets and configured to control an airflow direction of air flowing through the plurality of outlets in a plurality of directions; a camera disposed at one side of the panel and directed toward an indoor space; and a controller configured to control the airflow direction controller based on images corresponding to the indoor space and captured by the camera. The controller may be configured to determine an activity level of an occupant for each of a plurality of areas of the indoor space based on a plurality of images corresponding to the indoor space; determine a direction of air discharged from the plurality of outlets based on the determined activity level; and control the airflow direction controller according to the direction of the air which is determined for the plurality of outlets.
