Claim Text:
1. An air conditioner installed in a room, comprising: an infrared sensor which detects a temperature of an area of the room by scanning the area; and a microprocessor which acquires thermal image data of the area scanned by the infrared sensor, calculates, from the acquired thermal image data, a temperature T_left of a left wall located on a left side when viewed from the air conditioner, a temperature T_front of a frontal wall located in front of the air conditioner, a temperature T_right of a right wall located on a right side when viewed from the air conditioner, each of the left wall, the frontal wall, and the right wall being a wall of the room, a temperature Tf. ave of a floor of the room, a distance X_left between the left wall and an installation position of the air conditioner, a distance Y_front between the frontal wall and the installation position, and a distance X_right between the right wall and the installation position, detects a human body present in the room from the acquired thermal image data, and calculates where T_calc is a radiation temperature from the wall and the floor of the room for the human body, Xf is an X coordinate indicating a position where the human body is detected in a right and left direction of the room when viewed from the air conditioner, Yf is a Y coordinate indicating the position where the human body is detected in a depth direction of the room when viewed from the air conditioner, and α, β, and γ are correction coefficients, the microprocessor configured to control at least one of an air outlet temperature, an air outlet direction and an air outlet volume based on the calculations.
