Embodiment approach 1

[0025] The configuration of the air conditioner according to Embodiment 1 will be described. figure 1 It is a refrigerant circuit diagram showing a configuration example of the air conditioner according to Embodiment 1 of the present invention. Such as figure 1 As shown, the air conditioner 100 has an indoor unit 1 installed on a wall surface of a room, and an outdoor unit 15 connected to the indoor unit 1 via a refrigerant pipe 109 . The outdoor unit 15 has a heat source side heat exchanger 102 for exchanging heat with outside air, a compressor 13 for compressing and discharging refrigerant, an expansion valve 101 for reducing the pressure of the refrigerant, and a four-way valve for switching the flow path of the refrigerant. Valve 108. The indoor unit 1 has a fan 12 and a load-side heat exchanger 103 that exchanges heat with indoor air. The compressor 13 , the heat source side heat exchanger 102 , the expansion valve 101 , and the load side heat exchanger 103 connected v...

Embodiment approach 2

[0080] refer to Figure 11 ~ Figure 13 An air conditioner according to Embodiment 2 will be described. Figure 11 It is a block diagram showing a configuration example of the air conditioner according to Embodiment 2 of the present invention. Figure 12 It is a flowchart showing the procedure of the air-conditioning control method executed by the air conditioner according to Embodiment 2 of the present invention. Figure 13 is showing Figure 11 The shown image is an example of a thermal image transmitted from the human body position determination unit to the outer shape determination unit.

[0081] refer to Figure 11 The structure of the air conditioner of this Embodiment 2 is demonstrated. In this second embodiment, Figure 11 Among the shown configurations, the configurations other than the outer shape judging unit 25, the temperature distribution judging unit 26, and the attribute determining unit 7 are the same as those of the first embodiment. Figure 2A The descr...

Abstract

This air conditioner has: a refrigerant circuit that includes a compressor provided in an outdoor unit and a load-side heat exchanger provided in an indoor unit; a fan that is provided in the indoor unit; a flap that is provided in an outlet of the indoor unit; an infrared sensor that detects temperature distribution in a room; and a control device. The control device has: a body position determining means for determining a body part and position corresponding to a person in a thermal image detected by the infrared sensor; a distance determining means for calculating the distance from the indoor unit to the person using information on the position of the body part; a posture discriminating means for discriminating the posture of a person from the shape of the body part in the thermal image; an attribute determining means for discriminating whether the person has the attribute of an adult or child with respect to the number of pixels of the body part; and an operation controlling meansfor controlling at least one of the direction of the flap, the speed of the fan, and the speed of the compressor in accordance with the attribute.

Description

technical field [0001] The present invention relates to an air conditioner including an indoor unit capable of changing the discharge direction of air. Background technique [0002] Patent Document 1 discloses an example of an air conditioner that controls air volume and air direction in consideration of obstacles such as furniture placed indoors. Patent Document 1 describes a case in which an air conditioner uses an image sensor to recognize the shape of a measurement object determined to be a person, and determines whether the measurement object is a child or an adult, thereby adjusting the rotation speed of the indoor fan, the left and right louvers, and The upper and lower louvers are positioned so that the wind is concentrated around the adults and away from the children so that the wind does not directly blow on the children. [0003] In addition, Patent Document 1 describes that the image sensor installed in the indoor unit measures in advance the distance from the i...
