Claims (8)

A blower and a heat exchanger are provided between the suction port and the plurality of outlets, and each of the plurality of outlets includes a wind direction variable means for guiding an air flow from the blower, and the ceiling side of the air-conditioned space. An indoor unit installed in an embedded state or suspended state,
A suction temperature sensor that detects the temperature of air that is attached to the indoor unit and sucked into the suction port;
A radiation sensor attached to the indoor unit so as to detect radiation temperatures of a plurality of areas in a direction deviated from the direction of the airflow blown out from the blower outlet in plan view;
A control device for performing a process of controlling the wind direction of the air guide means based on radiation temperatures of a plurality of areas detected by the radiation sensor;
An air conditioner comprising:   The control device calculates an average value, a maximum value, and a minimum value of the radiation temperature based on the radiation temperatures of a plurality of areas detected by the radiation sensor, and an intake air temperature detected by the suction temperature sensor And the average sensory temperature is calculated based on the average value of the radiation temperature, the difference between the set temperature and the average sensory temperature is not more than a predetermined value, and the difference between the maximum value and the minimum value of the radiation temperature is not less than a predetermined value. 2. A process of setting the wind direction on the high load area side defined by the maximum value or the minimum value of the radiation temperature downward and setting the wind direction on the other area side to a direction other than downward. The air conditioner described. A remote controller or control board having a setting switch for setting an area to be air-conditioned with priority is provided, and the control device corrects and controls the area set by the setting switch to a high load side. The air conditioner according to claim 1 or 2 . The high-load area is an area having a maximum value of the radiation temperature during cooling operation, or an area having a minimum value of the radiation temperature during heating operation. 2. The air conditioner according to 2 . The control device calculates a sensible temperature of the high load area based on a suction air temperature detected by the suction temperature sensor and a radiation temperature of the high load area, and controls the air volume of the blower based on the sensible temperature. The air conditioner according to any one of claims 2 to 4, wherein the air conditioner is performed.   The air conditioner according to any one of claims 1 to 5, wherein the temperature measured by the radiation sensor is displayed on a remote controller.   The air conditioner according to any one of claims 1 to 6, wherein a current wind direction is displayed on a remote controller.   A decorative panel is provided on the lower surface of the indoor unit, and the decorative panel is provided with the inlet at the center, the outlet on the four sides surrounding the inlet, and the radiation sensor at one corner. 8. The sensor according to claim 1, wherein the sensor is attached so as to be able to detect a radiation temperature in an area between the adjacent air outlets, which is a direction deviated from a direction of an air flow blown from the air outlet. The air conditioner described in Crab.
