Abstract

An air conditioner has a housing having an air inlet opening and an air outlet opening, a heat exchanger placed in the housing, a fan sucking air in a room from the air inlet opening and discharging the air from the air outlet opening after causing the air to pass through the heat exchanger, horizontal louver plates placed in an outlet air flow path of the fan, vertical louver plates, and infrared detection device having at least first and second infrared sensors and estimating the presence of a person in the room by dividing the inside of the room into multiple regions. The first and second infrared sensors are arranged so that portions of the detection ranges thereof overlap each other, and depending on outputs from the first and second infrared sensors, the air conditioner determines whether the region in which the detection ranges overlap alone is a region where a person is present. Thus, the region where the person is present is distinguished without an increase in the number of human detection sensors, and the air conditioner can automatically perform comfortable operation and energy saving operation according to conditions of the person in the room.
