Problems solved by technology

[0003] However, the indoor temperature detected by the temperature sensor on the indoor unit only represents the temperature near the indoor unit, and the air density in the room is unbalanced, so the air conditioner is controlled according to the indoor temperature detected by the temperature sensor on the indoor unit to achieve temperature The adjustment of the air conditioner leads to a certain deviation between the temperature adjustment of the air conditioner and the user's demand.
In addition, when the temperature sensor on the indoor unit has a fault such as short circuit or open circuit, the air conditioner basically cannot operate normally.

Embodiment 1

[0077] In this embodiment, the air conditioner is in cooling mode, T11 represents the first indoor temperature detected by the first temperature sensor on the indoor unit of the air conditioner, and T12 represents the second indoor temperature detected by the second temperature sensor on the remote controller of the air conditioner. Indoor temperature, T4 indicates the outdoor ambient temperature, and T1 indicates the comprehensive indoor temperature.

[0078] When 丨T11-T12丨>4℃, That is, when there is a temperature difference between T11 and T12 above 4°C, the comprehensive indoor temperature takes the average value of the two; when 丨T11-T12丨≤4℃, the comprehensive indoor temperature is determined according to T4, which can prevent the second temperature on the remote control The position of the sensor is extreme or there is a great deviation due to interference by other signals, resulting in poor adjustment effect of the air conditioner.

[0079] When T4>35°C, T1=max(T11; T1...

Embodiment 2

[0083] In this embodiment, the air conditioner is in cooling mode, T11 represents the first indoor temperature detected by the first temperature sensor on the indoor unit of the air conditioner, and T12 represents the second indoor temperature detected by the second temperature sensor on the remote controller of the air conditioner. Indoor temperature, T4 indicates the outdoor ambient temperature.

[0084] When 丨T11-T12丨>4℃, That is, when there is a temperature difference between T11 and T12 above 4°C, the comprehensive indoor temperature takes the average value of the two; when 丨T11-T12丨≤4℃, the comprehensive indoor temperature is determined according to T4, which can prevent the second temperature on the remote control The position of the sensor is extreme or there is a great deviation due to interference by other signals, resulting in poor adjustment effect of the air conditioner. specifically,

[0085] When T4<7°C, T1=min(T11; T12), that is, when T4<7°C, the integrated ...

Abstract

The invention provides a control method, control device and control system of an air conditioner. The control method comprises the following steps that: first indoor air temperature is detected through a first temperature sensor in the indoor unit of the air conditioner, and second indoor air temperature is detected through a second temperature sensor of the remote controller of the air conditioner; whether the difference value of the first indoor air temperature and the second indoor air temperature is larger than a preset difference value is judged; and the comprehensive indoor temperature of the air conditioner is determined according to judging results, and the air conditioner is controlled according to the comprehensive indoor temperature. With the control method, control device and control system of the air conditioner provided by the technical scheme of the invention adopted, more accurate control on the air conditioner can be realized, and therefore, temperature adjustment of the air conditioner more accord with the needs of the user, and the reliability of the operation of the air conditioner can be improved.

Description

technical field [0001] The present invention relates to the technical field of household appliances, in particular to an air conditioner control method, an air conditioner control device and an air conditioner control system. Background technique [0002] At present, the functions of air conditioners are becoming more and more diversified and intelligent. Among them, the temperature sensor is the premise and guarantee for the intelligent operation of the air conditioner, and there is usually only one temperature sensor for the air conditioner, which is generally installed on the indoor unit of the air conditioner. , used to detect the indoor temperature. [0003] However, the indoor temperature detected by the temperature sensor on the indoor unit only represents the temperature near the indoor unit, and the air density in the room is unbalanced, so the air conditioner is controlled according to the indoor temperature detected by the temperature sensor on the indoor unit to ...
