Embodiment 1

[0061] 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:

[0062] 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.

[0063] Once a person is detected in the room, it will be processed according to the occupancy mode.

[0064] 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

[0082] 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:

[0083] 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.

[0084] In this step S4, the somatosensory temperature is corrected in the following manner:

[0085] If T a -2℃≤TEMP≤T a +2°C, then directly use the calculated TEMP as the corrected temperature;

[0086] If TEMPa -2°C, then set T a -2°C as the correction temperature;

[0087] If TEMP>T a +2℃, then set T a +2°C is used as the correction temperature.

[0088] 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

[0090] 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:

[0091] 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.

[0092] 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 a control method and device for an air conditioner. The control method for the air conditioner comprises the steps that the influence of the indoor temperature on the felt air temperature is studied in advance, and a formula for calculating the felt air temperature by means of the humidity and the indoor environment temperature is set. Based on the formula, when it is detected that a person is located in a room and the current indoor environment temperature value and the current humidity value meet preset conditions, the current felt air temperature of a human body is calculated by means of the calculation formula, the current felt air temperature of the human body is sent to an outdoor unit of the air conditioner, then the indoor temperature can be adjusted through the outdoor unit in the later stage based on the current felt air temperature of the human body, and finally the set temperature can be made to be matched with the felt air temperature of the human body. According to the control method and device for the air conditioner, the factors influencing the felt air temperature are comprehensively considered; compared with the prior art that the current indoor temperature is taken as the base temperature for temperature adjustment, the control method and device for the air conditioner have the advantages that due to the fact that the current felt air temperature of the human body is taken as the base temperature, the final felt air temperature of a user can be matched with the set temperature, and the sensing comfort level of the user is improved.

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 ...
