Problems solved by technology

[0003] The above-mentioned method of using two sensors to detect and realize control can timely adjust the operating status of the air conditioner according to changes in the environment, but due to the limited parameters collected by each sensor, it can only achieve unilateral control and cannot comprehensively control the environment. Therefore, the existing methods have a single control effect, low intelligence, are not humanized enough, and cannot achieve a balanced control of energy saving and comfort.

Embodiment 1

[0047] Taking the cooling room operation mode as an example, the flow of the control method of the present invention will be described in detail below.

[0048] see image 3 And Table 1, the air conditioner is running in the cold room mode. When the human body sensor and the light sensor are both turned on, the human activity and light intensity are detected at the same time, and the level is judged.

[0049]In this embodiment, the small comparison value (A) of the illuminance is set to 20 Lux, and the large comparison value (B) of the illuminance is set to 500 Lux. The set values ​​can be set according to actual needs, but A20Lux, compare the current light intensity value R with the maximum illuminance comparison value (B). If 20Lux≤R<500Lux, the judgment level is medium illuminance (ST2); if R≥500Lux, the judgment level is high illuminance (ST1).

[0050] In this embodiment, the current light intensity value R is 600 Lux, so it can be determined that the light intensity lev...

Embodiment 2

[0052] The difference between embodiment 2 and embodiment 1 is that when comparing the current light intensity value R with the maximum illuminance comparison value B, if R≥B is satisfied, and the time of R≥B lasts for T minutes, then the level is judged to be High illuminance (ST1). The duration T minutes can be set according to actual needs. In this embodiment, set T to 2 minutes, set the maximum illuminance comparison value B to 500Lux, and set the current light intensity value R to 600Lux, which satisfies the condition of R>B, but R drops rapidly to 450Lux within 2 minutes, so , does not meet the condition of high illuminance (ST1), the light intensity level should be determined as medium illuminance (ST2). Simultaneously, according to the amount of human body activity in the target area detected by the human body induction sensor, it is determined that the level of the amount of human body activity is quiet. Based on the test results of medium and quiet illumination, re...

Embodiment 3

[0054] Taking the warming room operation mode as an example below, considering the difference in the intensity of natural light in winter and summer, the difference between embodiment 3 and embodiment 1 lies in the setting value used to determine the level of light intensity in the warming room, namely: The small comparison value of illuminance (A') and the large comparison value of illuminance (B') are different from the A and B values ​​in the cold room. The setting value can be set according to actual needs, but must satisfy A'<B'.

[0055] Compared with the prior art, the air conditioner energy-saving control method of the present invention combines the human body induction sensor and the light sensor, so that the air conditioner can detect both human body activity and light intensity at the same time, and realizes two kinds of sensor functions The superposition of comprehensive detection results can make more accurate intelligent control of the current indoor environment....

Abstract

The invention discloses a method for controlling an air conditioner; in the method, a body sensing sensor, an optical sensor and an air conditioner control chip are used; the method comprises the following steps of: judging whether to turn on the body sensing sensor; when the body sensing sensor is turned on, detecting the body physical activity in a target area, and simultaneously judging whether to turn on the optical sensor; when the optical sensor is turned on, detecting the present light intensity, judging the level of the light intensity, and simultaneously judging the level of the bodyphysical activity; and correspondingly controlling the operation frequency of a compressor of the air conditioner, the indoor operation wind volume and the wind direction according to the detected levels of the body physical activity and the light intensity. The control method strengthens energy-saving effect and comfortable effect, thereby having high intelligent control degree, flexible function and humanized design.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an air conditioner control method. Background technique [0002] Existing air conditioners usually use human body induction sensors to detect the amount of human activity and location, or use light sensors to detect the intensity of sunlight in the room, and control the operation of the air conditioner according to the detected results. For the control flow chart, please refer to figure 1 and figure 2 . Among them, the control of the human body induction sensor focuses on adjusting the wind direction, while the control of the light sensor is to adjust the frequency of the compressor according to the illuminance level. [0003] The above-mentioned method of using two sensors to detect and realize control can timely adjust the operating status of the air conditioner according to changes in the environment, but due to the limited parameters collected by each sensor, it can only ac...
