Air conditioner capable of sensing human body infrared radiation and wind direction control method thereof

Abstract

The invention discloses an air conditioner capable of sensing human body infrared radiation and a wind direction control method thereof, which belong to the field of air conditioners and aim at avoiding long-time direct contact between human bodies and wind supplied by the air conditioner. By arranging an infrared sensor (1) capable of receiving infrared with peak value ranging from 9 mu m to 12 mu m on the air conditioner, the air conditioner can sense positions of the human bodies. The detecting direction of the infrared sensor (1) and the wind outlet direction of the air conditioner form a certain angle, and the detecting range of the infrared sensor (1) in rotating is within the wind blowing range in the wind outlet direction of the air conditioner in rotating of a guiding blade (2). The condition that peak value of the infrared signals received by the infrared sensor (1) ranges from 9 mu m to 10 mu m means that human bodies stay within the detecting direction of the infrared sensor (1), so a control system orders a driving motor to stop operating, the wind outlet direction of the air conditioner is on one side of the human bodies, and accordingly long-time direct contact between the human bodies and the air conditioner can be avoided.

Description

technical field [0001] The invention belongs to the field of air conditioners, and in particular relates to an air conditioner capable of sensing human body infrared radiation and a wind direction control method thereof. Background technique [0002] Air conditioners generally include compressors, condensers, throttle valves, evaporators, control systems, housings, etc. The compressors mainly have the functions of sucking refrigerant, maintaining the low temperature of the evaporator, compressing refrigerant, and promoting refrigerant circulation; The main function of the evaporator is to make the high-temperature gaseous refrigerant release heat and condense into a liquid state; the throttle valve mainly plays the role of throttling and reducing the pressure of the refrigerant and making the evaporator low temperature; the evaporator is to make the low-pressure low-temperature liquid refrigerant absorb heat and vaporize into a gaseous state; The agent is a heat transfer med...

AI Technical Summary

Problems solved by technology

The air conditioner can bring coolness in the hot summer and warmth in the cold winter. However, the temperature of the air outlet from the air conditioner is quite different from that of the outside world. These two methods will make people in direct contact with the air supply of the air conditioner for a long time, which will easily cause people to catch a cold, dry skin, feel uncomfortable, and even affect the human endocrine system. Therefore, it should be avoided as much as possible. The above two methods are to avoid direct contact of the human body with the air supply of the air conditioner for a long time
