A temperature-detecting device includes a frame, a temperature-detecting unit, a driving unit, a rotation-controlling unit, and a controller. The temperature-detecting unit includes a sensor, a sensor cap, and a sensor case. The rotation-controlling unit is configured to stop rotation of the sensor cap when the temperature-detecting unit reaches a target angle that is over 360 degrees froma reference position, with the sensor case being kept rotated by the driving unit such that the sensor is displaced froman opening and is covered by the sensor case. The controller is configured to correct a temperature detected while the sensor is exposed at the opening, with reference to a temperature detected while the sensor is covered by the sensor case.

An air-conditioning apparatus having a refrigerant circuit, in which a compressor, an outdoor heat exchanger, an expansion device, and an indoor heat exchanger are connected by a pipe and refrigerant circulates in the pipe, includes an indoor fan configured to supply an indoor air to the indoor heat exchanger, and a controller configured to control the compressor and the indoor fan. The controller is configured to run the compressor at a start of a cooling operation, start running the indoor fan at less than a set minimum wind velocity after a first set time has elapsed since the compressor started operating, run the indoor fan at the set minimum wind velocity after a second set time has elapsed since the indoor fan started operating at less than the set minimum wind velocity, and run the indoor fan at a set wind velocity after a third set time has elapsed since the indoor fan started operating at the set minimum wind velocity.

Disclosed herein is an air conditioner. The air conditioner includes a housing having an inlet and an outlet, a blade having a plurality of discharge holes and provided to discharge air through the plurality of discharge holes, a first opening formed between one side of the blade near the inlet and the housing when the blade discharges air through the plurality of discharge holes, and a second opening formed between the housing and the other side opposite to the one side of the blade when the blade discharges air through the plurality of discharge holes.

An air conditioner and a method for controlling an air conditioner are provided. The air conditioner may include a case that forms a space therein with an open lower side; a panel that is disposed at lower side of the case, and has an inlet and a plurality of outlets disposed around the inlet; a fan that is disposed in the case; a plurality of wind adjuster that is disposed in each of the plurality of outlets, and adjusts a direction of air flowing through each of the plurality of outlets; a camera that obtains an image of an indoor space; and a controller that controls the plurality of wind adjusters based on image information obtained from the camera. The controller may divide the plurality of outlets into a first area outlet and a second area outlet, and adjust each of the plurality of wind adjusters so that airflows of air discharged through the first area outlet and airflows of air discharged through the second area outlet are formed differently.

An indoor unit for an air-conditioning apparatus includes an insulation box that has a space that receives a heat exchanger, an insulation panel that is disposed between the insulation box and an outer panel and that has an air inlet passage and an air outlet passage, and a casing to which the outer panel is attached. The casing contains the insulation box and the insulation panel. The insulation box has a first outside-air introduction passage that is located apart from the space and that is communicable with an outside of the casing. The insulation panel has a second outside-air introduction passage that is located apart from the air outlet passage and that is communicable between the first outside-air introduction passage and the air inlet passage.
