Embodiment Construction

[0037] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0038] The invention provides a human body heat source detection method for an air conditioner and its operating area. First, according to the predetermined difference between the body surface temperature value of the human body and the ambient background temperature value, combined with infrared scanning of the human body heat source within the field of view of the air conditioner , and then adjust the size of the predetermined difference according to the number of heat sources obtained through scanning, so that the air conditioner can detect effective human body heat sources. In this way, through the dynamic adjustment of the predetermined difference, it can avoid the problem that the heat source of the human body is not detected by the infrared sensor when the user's body surface temperature is consistent with the a...

Abstract

The invention discloses a human body heat source detection method of a running area of an air conditioner. The method comprises following steps: according to the reserved difference value between the body surface temperature value of the human body and the environment background temperature value, a human body heat source in the field angle of the air conditioner is scanned through infrared rays; according to the heat source number obtained through scanning, the reserved difference value is adjusted, and therefore the air conditioner can detect the effective human body heat source. The invention further discloses the air conditioner. The problem that when the body surface temperature of a user is not consistent with the environment temperature, the human body heat source is not detected by an infrared sensor, and the heat source disappears is solved.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to an air conditioner and a human body heat source detection method in an operating area thereof. Background technique [0002] When the air conditioner is running in the cooling or heating mode, it usually operates according to the parameter values ​​such as the temperature or wind speed preset by the user, and the air conditioner is sometimes not really suitable for the user after running according to the parameter preset by the user. In a relatively hot environment, set a relatively low temperature such as 20°C for refrigeration. After a period of time, the room temperature will drop rapidly. discomfort. To solve this problem, existing solutions utilize infrared sensors to detect the user's body surface temperature to automatically adjust the temperature to provide a comfortable indoor environment for the user. However, when the user's body surface temperature is consiste...
