Embodiment 1

[0060] Embodiment 1 of the present invention discloses an air conditioner control method. The method in this embodiment realizes temperature control of the air conditioner in manned mode. Please refer to figure 1 , the control method includes the following steps:

[0061] S1: When a person is detected in the room, judge whether the current indoor ambient temperature value and indoor humidity value meet the preset conditions.

[0062] Once a person is detected in the room, it will be processed according to the occupancy mode.

[0063] In this embodiment, the influence of indoor humidity on the perceived temperature is studied in advance, and based on this, the preset condition is set as T a ≥25℃ and U h ≥40%, that is, when this condition is met, the perceived temperature of the human body will be significantly different from the indoor ambient temperature. In order to improve user comfort, the air conditioner needs to consider the impact of indoor humidity when adjusting the ...

Embodiment 2

[0080] The second embodiment continues to optimize and improve the air-conditioning control method disclosed in the first embodiment, please refer to figure 2 , the method also includes:

[0081] S4: Correct the somatosensory temperature to obtain a corrected temperature, and use the corrected temperature instead of the somatosensory temperature as a new base temperature.

[0082] In this step S4, the somatosensory temperature is corrected in the following manner:

[0083] If T a -2℃≤TEMP≤T a +2°C, then directly use the calculated TEMP as the corrected temperature;

[0084] If TEMPa -2°C, then set T a -2°C as the correction temperature;

[0085] If TEMP>T a +2℃, then set T a +2°C is used as the correction temperature.

[0086] In this embodiment, the perceived temperature is corrected, and the obtained corrected temperature is used as the base temperature for temperature adjustment, which improves the reference value of the base temperature and further improves the pe...

Embodiment 3

[0088] This embodiment three continues to supplement and improve the air conditioning control method disclosed in the above embodiments, please refer to image 3 , the method also includes:

[0089] S5: If the indoor ambient temperature value and the indoor humidity value do not meet the preset conditions, perform compensation calculation on the indoor ambient temperature value using the indoor radiation temperature based on a preset compensation formula to obtain a compensated temperature.

[0090] The applicant has found through research that when the indoor ambient temperature value and indoor humidity value do not meet the T a ≥25℃ and U h When ≥40%, the radiation temperature of the indoor floor and walls becomes the main factor affecting the human body's somatosensory temperature, and at this time, the influence of humidity on the somatosensory temperature is small and negligible, so it is different from the first and second embodiments The processing flow, the present ...

Abstract

The invention discloses an air conditioner control method and device. The method studies the influence of indoor humidity on the perceived temperature in advance, and sets a calculation formula for calculating the perceived temperature by using the humidity and the indoor ambient temperature. On this basis, when someone is detected in the room, and the current indoor ambient temperature and indoor humidity meet the preset conditions, the calculation formula is used to calculate the current body temperature, and the current body temperature is sent to the outdoor unit of the air conditioner. Therefore, the subsequent outdoor unit can adjust the indoor temperature based on the current human body temperature, and finally the set temperature can match the human body temperature. It can be seen that the present invention comprehensively considers the factors that affect the body temperature. Different from the current indoor temperature as the basic temperature for temperature adjustment in the prior art, the present invention uses the current body temperature as the base temperature, which can make the user's final body temperature and The set temperature matches, improving the user's perceived comfort.

Description

technical field [0001] The invention belongs to the technical field of electric appliance control, and in particular relates to an air conditioner control method and device. Background technique [0002] At present, the air conditioner generally adjusts and controls the temperature according to the temperature value set by the user and the indoor ambient temperature value detected currently, and finally controls the indoor ambient temperature to the temperature value set by the user. [0003] When the user uses the air conditioner, the temperature value set by the user is often the temperature that the user wants to perceive according to his own needs, that is, the body temperature. For example, in the cooling mode, if the user sets the air conditioner temperature value to 26°C, it means that the user is The required body temperature is 26°C, and the air conditioner will adjust the indoor ambient temperature to 26°C. However, due to the influence of indoor humidity, indoor ...
