The embodiment provides a method for controlling air conditioner heat up to temperature shutdown, which can be applied to a controller of an air conditioner, and is shown in a flow chart of the air conditioner heat up to temperature shutdown control method shown in fig. 1, and the method mainly comprises the following steps of S102 to S106:
step S102: when the air conditioner heats up to Wen Tingji, the current initial indoor temperature and initial outdoor temperature are detected.
In the heating process of the air conditioner, if the indoor environment temperature is detected to be greater than the user set temperature, the heating is automatically stopped, so that the indoor environment temperature is close to the user set temperature. When the air conditioner heats up to Wen Tingji, the indoor environment temperature and the outdoor environment temperature at the time of temperature-up shutdown are detected based on the temperature sensor, respectively, and are respectively noted as an initial indoor temperature and an initial outdoor temperature.
Step S104: and periodically detecting the current indoor environment temperature, and calculating the attenuated inner ring temperature based on the current indoor environment temperature, the initial indoor temperature and the initial outdoor temperature.
When the air conditioner stops when reaching the temperature, the indoor environment temperature is in a decay trend and gradually decreases, the current indoor environment temperature is detected once every preset time (the value range can be 1-3 min, and the optimal value is 1 min), and the decayed inner ring temperature corresponding to the current period is calculated based on the detected indoor environment temperature each time and the initial indoor temperature and the initial outdoor temperature.
Step S106: judging whether the air conditioner meets the condition of recovering heat or not based on the current indoor environment temperature and the attenuated inner ring temperature, and if so, controlling the air conditioner to recover heat-producing operation.
In order to avoid the large difference between the detected current indoor environment temperature and the lower-layer cold air temperature sensed by a user when the indoor cold and hot air is layered, comprehensively judging whether the current indoor environment temperature meets the recovery heating condition according to the current indoor environment temperature and the attenuated inner ring temperature obtained by theoretical calculation, and controlling the air conditioner to recover heating operation if the recovery heating condition is met.
In a possible implementation manner, an average temperature value of the current indoor environment temperature and the attenuated inner ring temperature obtained in the current period can be calculated, and when the average temperature value is smaller than a preset recovery temperature, it is determined that the air conditioner meets the recovery heat recovery condition.
In another possible implementation, the minimum temperature value is obtained from the current indoor environment temperature obtained in the current period and the attenuated inner ring temperature; and when the minimum temperature value is smaller than the preset recovery temperature, determining that the air conditioner meets the recovery heat-transfer condition. The air conditioner can be controlled to resume heating operation as long as any one value of the current indoor environment temperature and the attenuated inner ring temperature is smaller than the preset resume temperature.
By taking the smaller value of the current indoor environment temperature and the attenuated inner ring temperature as the judgment temperature for recovering heat, if the current indoor environment temperature or the attenuated inner ring temperature is reduced to the preset recovery temperature, the air conditioner is controlled to recover heat, so that the recovery heat efficiency after heat and shutdown is improved, the influence on human comfort is avoided, and the user experience is improved.
According to the air conditioner heating temperature-reaching shutdown control method, after the air conditioner heating temperature-reaching shutdown, the current indoor environment temperature is periodically detected, the inner ring temperature of the indoor environment temperature decayed along with time is periodically calculated, whether the heat recovery is needed or not is judged according to the current indoor environment temperature and the decayed inner ring temperature, the situation that the user comfort is affected due to the detected current indoor environment temperature inaccurately is avoided, and the user experience is improved.
In a possible implementation manner, the embodiment provides an implementation manner of calculating the attenuated inner ring temperature based on the current indoor environment temperature, the initial indoor temperature and the initial outdoor temperature, and the implementation manner may be specifically performed with reference to the following steps (1) to (3):

The initial temperature difference is related to a difference between an initial indoor temperature and a user-set temperature, and is calculated based on the user-set temperature, the initial indoor temperature, and the initial outdoor temperature.
In one specific embodiment, the initial temperature difference is calculated as:
ΔT 0 ＝-[k1(TNR 0 -TWR 0 )+k2(TNR 0 -T setting up )]/t 0
Wherein DeltaT 0 T is the initial temperature difference Setting up TNR for setting temperature for user 0 TWR is the initial indoor temperature 0 For initial outdoor temperature, k1 is the temperature drop coefficient of indoor environment temperature, k2 is the temperature drop coefficient of outdoor environment temperature, k1, k2 are more than or equal to 0, and k1+k2=1, t 0 Is the initial maximum downtime. By calculating the initial temperature difference based on the calculation formula, the calculated initial temperature difference is related to the user set temperature, the initial indoor temperature and the initial outdoor temperature, the attenuation influence of the outdoor environment temperature on the current initial indoor temperature is comprehensively considered, and the rationality of heating temperature-reaching shutdown control is improved.
Step (2): and calculating the average attenuation temperature difference of the current period based on the initial temperature difference and the current indoor environment temperature, and determining the accumulated temperature drop based on the initial temperature difference and the average attenuation temperature difference of each period.
The calculation formula of the average attenuation temperature difference is as follows:
ΔT i ＝ΔT 0 *(TNR i -TNR recovery )/(TNR 0 -TNR Recovery )
Wherein TNR i TNR for the current indoor environment temperature detected in the current period i Recovery TNR for preset recovery temperature 0 Is the initial room temperature.
The calculation formula of the accumulated temperature drop is as follows:
ΔT＝ΔT 0 +ΔT 1 +ΔT 2 +……+ΔT i
ΔT 0 for initial temperature difference DeltaT i The average attenuation temperature difference corresponding to the current period i. The initial temperature difference is a negative value, and the average attenuation temperature difference and the accumulated temperature difference obtained by calculation based on the initial temperature difference are both negative values.
Considering that the indoor environment temperature is in a descending trend in one period, the average attenuation temperature difference of the indoor environment temperature in one period is approximately in inverse proportion to the current indoor environment temperature detected in the initial period of the period, the average attenuation temperature difference of the indoor environment temperature in the period can be obtained through calculation by inputting the current indoor environment temperature detected in the current period into the calculation formula, the actual condition of indoor environment temperature change is met, and an accurate basis is provided for calculating the attenuated inner ring temperature.
Step (3): and calculating the attenuated inner ring temperature according to the initial indoor temperature and the accumulated temperature drop.
The calculation formula of the attenuated inner ring temperature is as follows:
TNR calculation of ＝TNR 0 +ΔT
Wherein TNR Calculation of TNR for attenuated inner ring temperature 0 For the initial indoor temperature, deltaT is the accumulated temperature drop, the accumulated temperature drop is a negative value, the inner ring temperature after the initial indoor temperature gradually decays along with the time increase can be calculated by calculating the sum of the initial indoor temperature and the accumulated temperature drop, the problem that the heating is difficult to recover after the air conditioner thermal shutdown caused by the installation environment and other factors is reduced, the auxiliary effect is achieved on the detection of the indoor environment temperature, the heating recovery efficiency after the thermal shutdown is improved, and the accuracy and the rationality of the determination of the actual indoor environment temperature are improved.
By calculating the attenuation temperature difference of each period and calculating the attenuated inner ring temperature corresponding to the initial indoor temperature according to the initial temperature difference and the accumulated temperature drop generated by the average attenuation temperature difference of each period, the actual temperature condition of the initial indoor temperature after the temperature attenuation drop can be accurately reflected, whether the recovery heating condition is met at present can be accurately judged, and the influence on heating comfort caused by inaccurate current indoor environment temperature detected by an air conditioner is avoided.
In a possible implementation manner, the method provided by the embodiment further includes: if the minimum temperature value is greater than the preset recovery temperature, detecting the current indoor environment temperature of the next period, and calculating the average attenuation temperature difference of the next period and the attenuated inner ring temperature until the air conditioner meets the recovery heat transfer condition, and controlling the air conditioner to recover heat transfer operation.
In each detection period, if the minimum temperature value in the current indoor environment temperature and the attenuated inner ring temperature in the current period is larger than the preset recovery temperature, the condition of recovering heat is not met, temperature judgment is continued, namely the current indoor environment temperature in the next period is detected, the attenuated inner ring temperature in the next period is calculated according to the current indoor environment temperature in the next period, whether the condition of recovering heat is met or not is further judged, temperature detection is periodically executed, and whether the condition of recovering heat is met or not is judged, until the air conditioner meets the condition of recovering heat, and the air conditioner is controlled to recover heat to operate.
When the recovery heating condition is not met, the temperature detection and the judgment of the recovery heating condition are repeatedly carried out, so that the phenomenon that the indoor environment temperature is excessively reduced to cause cold feeling to a user is avoided, the comfort of the indoor environment temperature is ensured, and the user experience is improved.
According to the air conditioner heating up-to-temperature shutdown control method, through increasing the calculation of the attenuated inner ring temperature, when the detected current indoor environment temperature does not meet the recovery heating condition, but the attenuated inner ring temperature calculated value is met, the recovery heating is controlled, the problem that the recovery heating is difficult after the heating shutdown caused by factors such as installation environment and the like can be solved, the recovery heating efficiency after the heating shutdown is improved, and the comfortableness of the indoor environment is improved.
