[0002] When an inverter air conditioning unit (hereinafter referred to as "the unit") is running, if the indoor ambient temperature is close to the set temperature, the unit's operating frequency will decrease until it reaches its minimum frequency. When the heat released by the unit is equal to the heat consumed in the room, it is in thermal equilibrium. At this time, the outlet air temperature is relatively low, which can easily cause cold air to blow onto the user, affecting the user experience.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] The above solution requires the addition of an electric auxiliary heating device, which necessitates modifications to the air conditioner's structure. This is too costly.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0007] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0008] This disclosure provides a method, apparatus, air conditioning unit, and storage medium for controlling an air conditioning unit, reducing the amount of cold air blown on the user without adding a heating structure.

[0009] In some embodiments, the method includes: when the air conditioning unit is operating in heating mode, acquiring the indoor ambient temperature and the operating frequency of the air conditioning unit; when the temperature difference between the indoor ambient temperature and the set temperature is within a preset range and the operating frequency is the default minimum frequency, acquiring the indoor fan speed and the outlet air temperature; and adjusting the indoor fan speed or the default minimum frequency of the air conditioning unit according to the indoor fan speed and the outlet air temperature.

[0010] In some embodiments, the apparatus includes a processor and a memory storing program instructions, the processor being configured to execute the aforementioned method for controlling an air conditioning unit when the program instructions are executed.

[0014] When the air conditioning unit is operating in heating mode, it determines whether the room is in thermal equilibrium by judging the indoor temperature and the operating frequency of the air conditioning unit. If so, it further obtains the indoor fan speed and outlet air temperature to determine whether there is a risk of users being blasted with cold air. Based on the indoor fan speed and outlet air temperature, it adjusts the indoor fan speed or the unit's default minimum frequency to increase the outlet air temperature. In this way, no additional structure is needed, which can reduce the situation where users are blasted with cold air. Moreover, compared with adjusting the angle of the air deflector to reduce the situation of users being blasted with cold air, this method can still make the air outlet angle meet the user's expectations, resulting in a better user experience.

[0030] Combination Figure 1 As shown in the embodiments of this disclosure, a method for controlling an air conditioning unit is provided, comprising:

[0031] S101, the controller acquires the indoor ambient temperature and the operating frequency of the air conditioning unit when the air conditioning unit is operating in heating mode.

[0032] S102, the controller obtains the indoor fan speed and outlet air temperature when the temperature difference between the indoor ambient temperature and the set temperature is within the preset range and the operating frequency is the default minimum frequency.

[0033] S103, the controller adjusts the speed of the indoor fan or the default minimum frequency of the air conditioning unit according to the speed of the indoor fan and the air outlet temperature.

[0034] When the air conditioning unit (hereinafter referred to as "the unit") is operating in heating mode, the indoor temperature environment Tai is obtained through a temperature sensor installed indoors. Simultaneously, its own operating frequency is also obtained. The temperature difference ΔT1 between the indoor temperature environment Tai and the set temperature Ts is calculated. If ΔT1 is within a preset range, it indicates that Tai and Ts are close, and the indoor environment is in thermal equilibrium. The unit's operating frequency is further obtained and compared with the default minimum frequency. The default minimum frequency is the frequency set at the factory and is also the minimum frequency the unit can achieve. If the unit's operating frequency is the default minimum frequency, it indicates that the unit's current heating capacity is at its minimum. The indoor fan speed and outlet air temperature are then further obtained. If the indoor fan speed is too high and the outlet air temperature is too low, cold air will blow onto the user. Therefore, the indoor fan speed or the default minimum frequency is adjusted based on the indoor fan speed and outlet air temperature. Optionally, the higher the indoor fan speed and the lower the outlet air temperature, the more necessary it is to adjust the indoor fan speed or the default minimum frequency.

[0035] In this embodiment, when the air conditioning unit is operating in heating mode, the indoor temperature and the operating frequency of the air conditioning unit are used to determine whether the room is in thermal equilibrium. If so, the indoor fan speed and outlet air temperature are further obtained to determine if there is a risk of users being exposed to cold air. Based on the indoor fan speed and outlet air temperature, the indoor fan speed or the unit's default minimum frequency is adjusted to increase the outlet air temperature. This reduces the likelihood of users being exposed to cold air without requiring any additional structures. Moreover, compared to adjusting the angle of the air deflector to reduce cold air exposure, this method ensures that the outlet air angle still meets the user's expectations, resulting in a better user experience.

[0036] Optionally, when the temperature difference between the indoor ambient temperature and the set temperature is within a preset range, and the operating frequency is the default minimum frequency, the controller further obtains the unit's operating time under these conditions. When the operating time exceeds a time threshold, it indicates that the room has been in thermal equilibrium for some time. If the indoor fan outputs too much air and the temperature is too low, it is more likely to cause users to experience cold air. Therefore, when the operating time exceeds the time threshold, the fan speed or the default minimum frequency is adjusted based on the indoor fan speed and the air outlet temperature. Optionally, the time threshold is 4 to 5 minutes.

[0037] Optionally, in step S103, the controller adjusts the indoor fan speed or the default minimum frequency of the air conditioning unit based on the indoor fan speed and the outlet air temperature, including:

[0038] When the internal fan speed is greater than the speed threshold and the outlet air temperature is less than or equal to the temperature threshold, the controller will reduce the internal fan speed.

[0039] When the internal fan speed is at its lowest speed and the outlet air temperature is less than or equal to the temperature threshold, the controller increases the default minimum frequency of the air conditioning unit; where the lowest speed is greater than the speed threshold.

[0040] Since the indoor unit's airflow is directed at the user, the user is more sensitive to airflow speed. Therefore, the indoor fan speed is prioritized and adjusted accordingly. Speed ​​and temperature thresholds are set and pre-stored in the unit's controller. The preset speed is higher than the minimum speed. Optionally, the temperature threshold is 34-36℃. If the indoor fan speed is higher than the speed threshold and the outlet air temperature is lower than the temperature threshold, it indicates that the outlet airflow speed is too high and the outlet air temperature is too low, resulting in cold air blowing onto the user. However, there is still room for the indoor fan speed to decrease; therefore, the indoor fan speed is reduced. If the indoor fan speed is already at its minimum or has been reduced to its minimum, but the outlet air temperature is still less than or equal to the temperature threshold, the indoor fan speed cannot be further reduced; therefore, the unit's default minimum frequency is increased. This first controls the indoor fan speed to decrease, minimizing the impact of cold air on the user as quickly as possible. When the indoor fan speed is at its minimum, the unit's default minimum frequency is then increased, thereby increasing the unit's heating capacity and thus the outlet air temperature, further reducing the discomfort caused by cold air.

[0041] Optionally, the controller controls the internal fan speed to decrease, including:

[0042] The controller calculates the temperature difference between the air temperature and the temperature threshold.

[0043] The controller determines the target speed for regulating the internal fan based on the temperature difference.

[0044] The controller controls the internal fan speed to decrease at the target rate.

[0045] Calculate the temperature difference ΔT2 between the air temperature Tc and the temperature threshold T'. Determine the target speed for adjusting the indoor fan speed based on the temperature difference ΔT2. The larger the temperature difference ΔT2, the faster the adjustment needs to be, hence the higher the target speed. The controller has a pre-stored correlation between temperature differences and the indoor fan speed adjustment rate. This correlation includes one or more correspondences between temperature differences and the indoor fan speed adjustment rate. Optionally, this correlation can be found in Table 1.

[0046] Table 1. Relationship between temperature difference and internal fan speed control rate

[0047]

[0048] In Table 1, ΔT21 is the first temperature difference threshold, ΔT22 is the second temperature difference threshold, and ΔT21 > ΔT22. V1 > V2 > V3. For example, if ΔT2 is calculated to be between ΔT21 and ΔT22, then the target rate is determined to be V2. The internal fan speed is controlled to decrease by V2.

[0049] If, during the reduction of the indoor fan speed, the outlet air temperature exceeds the temperature threshold before reaching the minimum speed, the indoor fan speed will be maintained at its current level, meaning it will not continue to decrease. Otherwise, the indoor fan speed will continue to decrease until it reaches the minimum speed. Optionally, the outlet air temperature can be acquired every 4-5 minutes and compared with the temperature threshold.

[0050] This ensures that the rate at which the internal fan speed decreases matches the difference between the outlet air temperature and the temperature threshold, thus avoiding the problem of the speed decreasing too slowly and failing to alleviate the impact of the low-temperature outlet air on the user, or the speed decreasing too quickly and easily causing overshoot.

[0051] Optionally, the controller increases the default minimum frequency of the air conditioning unit, including:

[0052] The controller obtains the outdoor ambient temperature.

[0053] The controller determines the target minimum frequency and the target rate of the default minimum frequency adjustment for the air conditioning unit based on the outdoor ambient temperature.

[0054] The controller controls the air conditioning unit to increase its default minimum frequency to the target minimum frequency at the target rate.

[0055] The controller communicates with a temperature sensor located in the outdoor environment to obtain the outdoor ambient temperature, Tao. When reducing the indoor fan speed is insufficient to prevent the cooling effect on users, the default minimum frequency of the unit is further increased. Based on the outdoor ambient temperature, the target minimum frequency fm of the unit and the target rate V' for adjusting the default minimum frequency are determined.

[0056] The lower the outdoor ambient temperature Tao, the greater the required heating capacity indoors and the more urgent the need for rapid adjustment, resulting in larger fm and V'. The controller pre-stores the correlation between the outdoor ambient temperature and the adjustment rates of the minimum frequency and the default minimum frequency. This correlation includes one or more corresponding relationships between the outdoor ambient temperature and the adjustment rates of the minimum frequency and the default minimum frequency. Optionally, this correlation is shown in Table 2 for reference.

[0057] Table 2 Correlation between outdoor ambient temperature and adjustment rates of the minimum frequency and the default minimum frequency

[0058]

[0059] In Table 2, Tao1 is the first outdoor temperature threshold, Tao2 is the second outdoor temperature threshold, and Tao1 > Tao2. V1' < V2' < V3', and fm1 < fm2 < fm3. For example, if the calculated Tao is between Tao1 and Tao2, it is determined that the target minimum frequency is fm2 and the target rate is V2'. The rotational speed of the indoor fan is controlled to increase to fm2 at the rate of V2'.

[0060] Optionally, V1' is 1Hz / s, V2' is 1.5Hz / s, and V3' is 2Hz / s.

[0061] In this way, the target minimum frequency and target adjustment rate of the unit are matched with the outdoor ambient temperature, so that the outlet air temperature is appropriate.

[0062] As shown in connection with Figure 2 , an embodiment of the present disclosure provides another method for controlling an air conditioning unit, including:

[0063] In S101, when the air conditioning unit operates in a heating mode, the controller acquires the indoor ambient temperature and the operating frequency of the air conditioning unit.

[0064] In S102, under the condition that the temperature difference between the indoor ambient temperature and the set temperature is within a preset range and the operating frequency is the default minimum frequency, the controller acquires the rotational speed of the indoor fan and the outlet air temperature.

[0065] In S103, the controller regulates the rotational speed of the indoor fan or the default minimum frequency of the air conditioning unit according to the rotational speed of the indoor fan and the outlet air temperature.

[0066] In S104, while the controller executes S103, the controller acquires the change rate of the indoor ambient temperature.

[0067] In S105, the controller corrects the regulation rate for the rotational speed of the indoor fan or the default minimum frequency according to the change rate of the indoor ambient temperature.

[0068] S106: After executing S103 and S105, the controller will shut down the air conditioning unit if the indoor ambient temperature is higher than the set temperature.

[0069] During the adjustment of the indoor fan speed or the default minimum frequency, the indoor ambient temperature will increase. The rate of change (rate of increase) of the indoor ambient temperature is obtained. The smaller the rate of change, the slower the air outlet temperature rises, and the longer the cooling effect on the user lasts. To shorten the duration of the cooling effect on the user, the adjustment rate of the indoor fan speed or the default minimum frequency is adjusted based on the rate of change. Optionally, the larger the rate of change, the smaller the adjustment value.

[0070] The controller pre-stores the rate of change V of the indoor ambient temperature. T The correlation between V and the correction value ΔV for the speed regulation rate of the internal fan. T The larger the value, the smaller ΔV. Specifically, optionally, this relationship is shown in Table 3.

[0071] Table 3. Relationship between the rate of change of indoor ambient temperature and the correction value of the controlled indoor fan speed.

[0072]

[0073] In Table 3, V T 1 represents the threshold value for the first indoor ambient temperature change rate, V T 2 represents the threshold for the rate of change of the second indoor ambient temperature, V T 1>V T 2. ΔV1 < ΔV2 < ΔV3. Optionally, ΔV1 is 0.

[0074] For example, calculate V T Located in V T 1 and V T If the value is between 2 and 3, then the correction value is determined to be ΔV2. If the internal fan speed is reduced at a rate of V1 at this time, then V1 is corrected to V1+ΔV2, that is, the internal fan speed is reduced at a rate of V1+ΔV2.

[0075] The controller pre-stores the rate of change V of the indoor ambient temperature. T The correlation between V and the default minimum frequency control rate correction value ΔV' and the minimum frequency control rate correction value Δfm. T The larger the value, the smaller ΔV' and Δfm. Specifically, optionally, this relationship is shown in Table 4.

[0076] Table 4. Relationship between the rate of change of indoor ambient temperature and the correction value of the minimum frequency, as well as the correction value of the minimum frequency control rate.

[0077]

[0078] In Table 4, ΔV1'<ΔV2'<ΔV3', Δfm1<Δfm2<Δfm3. Optionally, ΔV1' is 0, ΔV2' is 0.5Hz / s, ΔV3' is 1Hz / s, Δfm1 is 0Hz, Δfm1 is 5Hz, and Δfm1 is 10Hz.

[0079] For example, calculate V T Located in V T 1 and V T If the values ​​are between 2, then the correction values ​​are determined to be ΔV2' and Δfm2. If the default minimum frequency of the control unit increases to fm1 at the rate of V1', then V1' is corrected to V1'+ΔV2', and fm1 is corrected to fm1+Δfm2, that is, the default minimum frequency of the control unit increases to fm1+Δfm2 at the rate of V1'+ΔV2'.

[0080] During the adjustment of the internal fan speed and default minimum frequency, the indoor ambient temperature is acquired in real time. When the indoor ambient temperature is higher than the set temperature, it indicates that the indoor ambient temperature has reached the user's expectations or is within a suitable range, and the unit is then controlled to shut down.

[0081] Combination Figure 3 As shown in the embodiments of this disclosure, another method for controlling an air conditioning unit is provided, including:

[0082] S101, the controller obtains the indoor ambient temperature and the operating frequency of the air conditioning unit when the air conditioning unit is running in heating mode.

[0083] S102, the controller obtains the indoor fan speed and outlet air temperature when the temperature difference between the indoor ambient temperature and the set temperature is within the preset range and the operating frequency is the default minimum frequency.

[0084] S103, the controller adjusts the speed of the indoor fan or the default minimum frequency of the air conditioning unit according to the speed of the indoor fan and the air outlet temperature.

[0085] S104: While executing S103, the controller acquires the rate of change of the indoor ambient temperature.

[0086] S105, the controller adjusts the speed of the indoor fan or the default minimum frequency according to the rate of change of the indoor ambient temperature.

[0087] S106: After executing S103 and S105, the controller will shut down the air conditioning unit if the indoor ambient temperature is higher than the set temperature.

[0088] S107, the controller obtains the historical minimum frequency when the air conditioning unit is operating in heating mode.

[0089] S108, the controller determines the default minimum frequency for the next heating operation of the air conditioning unit based on the historical minimum frequency.

[0090] When the unit is shut down, the minimum operating frequency of the unit during each historical heating operation before shutdown is obtained. This minimum frequency includes both the default minimum frequency and the target minimum frequency obtained after adjusting the default minimum frequency. Optionally, when the unit itself is shut down, the minimum operating frequency of the unit before shutdown during the previous 5 heating operations is obtained. The average frequency of these minimum frequencies is calculated and used as the new default minimum frequency for the next heating operation. Therefore, during the next heating operation, if the temperature difference between the indoor ambient temperature and the set temperature is within a preset range, the unit's frequency is reduced to the new default minimum frequency. In this way, updating the unit's default minimum frequency based on historical control data can prevent the problem of users experiencing cold air when the indoor environment is in thermal equilibrium and the airflow speed is high during the next heating operation.

[0091] Combination Figure 4 As shown in the embodiments of this disclosure, another method for controlling an air conditioning unit is provided, including:

[0092] S101, the controller obtains the indoor ambient temperature and the operating frequency of the air conditioning unit when the air conditioning unit is running in heating mode.

[0093] S102, the controller obtains the indoor fan speed and outlet air temperature when the temperature difference between the indoor ambient temperature and the set temperature is within the preset range and the operating frequency is the default minimum frequency.

[0094] S103, the controller adjusts the speed of the indoor fan or the default minimum frequency of the air conditioning unit according to the speed of the indoor fan and the air outlet temperature.

[0095] S104: While executing S103, the controller acquires the rate of change of the indoor ambient temperature.

[0096] S105, the controller adjusts the speed of the indoor fan or the default minimum frequency according to the rate of change of the indoor ambient temperature.

[0097] S106: After executing S103 and S105, the controller will shut down the air conditioning unit if the indoor ambient temperature is higher than the set temperature.

[0098] S107, the controller obtains the historical minimum frequency when the air conditioning unit is operating in heating mode.

[0099] S108, the controller determines the default minimum frequency for the next heating operation of the air conditioning unit based on the historical minimum frequency.

[0100] S109, The controller obtains the time elapsed from the start of adjusting the indoor fan speed or the default minimum frequency of the air conditioning unit to the indoor ambient temperature exceeding the set temperature during the current heating operation of the air conditioning unit.

[0101] S110, the controller adjusts the internal fan speed or the default minimum frequency adjustment rate based on the duration of the event.

[0102] S111, the controller will use the corrected control rate as the default control rate when the air conditioning unit is running in heating mode and needs to adjust the speed of the indoor fan or the default minimum frequency.

[0103] During the unit's heating operation, timing begins from the moment the indoor fan speed is adjusted to the default minimum frequency. Timing stops when the indoor ambient temperature exceeds the set temperature. The duration t of this process is calculated.

[0104] When the control unit stops, the elapsed time t is obtained. Based on the elapsed time t, the adjustment rate V of the indoor fan speed or the adjustment rate V' of the default minimum frequency is adjusted. The larger t is, the slower the indoor ambient temperature is adjusted, and therefore, in order to improve the user experience, the larger the adjustment values ​​of V and V' are.

[0105] The controller pre-stores the correlation between the duration of the experience and the adjustment rate of the internal fan speed, as well as the correction value of the adjustment rate of the default minimum frequency. Specifically, optionally, this correlation is shown in Table 5.

[0106] Table 5 shows the correlation between the duration of the experience and the adjustment rate of the internal fan speed and the correction value of the default minimum frequency adjustment rate.

[0107]

[0108] In Table 5, t1 is the first duration threshold, t2 is the second duration threshold, and t1>t2. W1>W2>W3, W1'>W2'>W3'. Optionally, W3 is 0, and W3' is 0.

[0109] For example, if t is calculated to be between t1 and t2, then the correction values ​​are determined to be W3 and W3'. Therefore, ΔV1, ΔV2, and ΔV3 are corrected to ΔV1+W3, ΔV2+W3, and ΔV3+W3, respectively, and ΔV1', ΔV2', and ΔV3' are corrected to ΔV1'+W3', ΔV2'+W3', and ΔV3'+W3', respectively.

[0110] When the unit is running in heating mode again and it is necessary to adjust the internal fan speed or the default minimum frequency, the adjusted rate of the internal fan speed and the adjusted rate of the default minimum frequency will be used as the default adjustment rate.

[0111] In this way, based on the duration of this control process, the speed of the indoor fan and the control rate of the default minimum frequency are corrected, and the control situation of this time is fed back to the next control process to shorten the duration of the cold air's impact on users and improve the user experience.

[0112] Combination Figure 5 As shown in the illustration, this disclosure provides an apparatus 50 for controlling an air conditioning unit, including: a first acquisition module 51, a second acquisition module 52, and a control module 53.

The control module 53 is configured to adjust the indoor fan speed or the default minimum frequency of the air conditioning unit based on the indoor fan speed and the outlet air temperature.

[0113] The device for controlling an air conditioning unit provided in this disclosure is advantageous in determining whether the room is in thermal equilibrium when the air conditioning unit is operating in heating mode, by judging the indoor temperature and the operating frequency of the air conditioning unit. If so, the indoor fan speed and outlet air temperature are further obtained to determine whether there is a risk of users being exposed to cold air. Based on the indoor fan speed and outlet air temperature, the indoor fan speed or the unit's default minimum frequency is adjusted to increase the outlet air temperature. In this way, no additional structure is required, reducing the likelihood of users being exposed to cold air. Moreover, compared with adjusting the angle of the air deflector to reduce the amount of cold air, this method ensures that the outlet air angle still meets the user's expectations, resulting in a better user experience.
