Description

Technical Field

[0001] This application relates to the field of smart home appliance technology, such as a method, apparatus, air conditioner, and storage medium for controlling an air conditioner. Background Technology

[0002] During operation, an air conditioner uses a cross-flow fan to create positive and negative air pressure within the duct, drawing air in through the air inlet, passing it through the indoor heat exchanger, and then blowing it out through the air outlet. The air exchanges energy with the indoor heat exchanger, achieving the cooling or heating effect. Therefore, the airflow volume of an air conditioner determines its efficiency. In actual use, various factors can cause the airflow volume to decrease, leading to a reduction in the air conditioner's efficiency. Summary of the Invention

[0003] 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.

[0004] This disclosure provides a method, apparatus, air conditioner, and storage medium for controlling an air conditioner to ensure its operating efficiency.

[0005] In some embodiments, the method for controlling an air conditioner includes: acquiring the actual air outlet speed of the air conditioner; determining the adjustment requirements for the operation of the air conditioner based on the actual air outlet speed; if the adjustment requirements are required, determining the target temperature of the inner coil based on the current operating state of the air conditioner; and controlling the compressor frequency and / or the opening degree of related valves to increase so that the temperature of the inner coil reaches the target temperature.

[0006] In some embodiments, the apparatus for controlling an air conditioner includes a processor and a memory storing program instructions, the processor being configured to execute the aforementioned method for controlling an air conditioner when the program instructions are executed.

[0007] In some embodiments, the air conditioner includes: an air conditioner body; and a device for controlling the air conditioner as described above, which is installed on the air conditioner body.

[0008] In some embodiments, the storage medium stores program instructions that, when executed, perform the aforementioned method for controlling an air conditioner.

[0009] The method, apparatus, air conditioner, and storage medium for controlling an air conditioner provided in this disclosure can achieve the following technical effects:

[0010] First, obtain the actual airflow velocity of the air conditioner. Airflow velocity characterizes the air volume. When the air conditioner's efficiency is determined to be reduced based on the airflow velocity, indicating a need for adjustment during operation, the primary reason is the reduced airflow. In this case, based on the current operating state of the air conditioner, determine the target temperature for the indoor coil. By controlling the compressor frequency and / or increasing the opening of relevant valves, the temperature of the indoor coil is brought to the target temperature, thereby changing the outlet air temperature of the indoor unit to quickly reach the user's desired indoor temperature. In this way, by adjusting the temperature of the indoor coil, i.e., adjusting the outlet air temperature, the temperature loss caused by the reduced airflow is compensated for, thus ensuring the air conditioner's operating efficiency.

[0026] Combination Figure 1 As shown in the embodiments of this disclosure, a method for controlling an air conditioner is provided, comprising:

[0027] S101, the air conditioner obtains its actual airflow speed.

[0028] S102, the air conditioner determines its operating adjustment requirements based on the actual airflow speed.

[0029] S103, when the air conditioner requires adjustment, it determines the target temperature of the indoor coil based on its current operating status.

[0030] S104, the frequency of the air conditioning control compressor and / or the opening degree of the relevant valve body are increased so that the temperature of the inner coil reaches the target temperature.

[0031] Users can send a start command to the air conditioner via remote control or terminal device. The air conditioner turns on after receiving the command. After a period of time, the air conditioner enters a stable operating state. At this time, the actual airflow velocity V1 of the air conditioner is obtained. From the formula M = V1 * R (where M is the airflow volume and R is the air outlet area), it can be seen that once the air conditioner is running stably, the airflow velocity determines the airflow volume. Therefore, the airflow velocity can be used to characterize the airflow volume to determine whether the air conditioner's airflow volume has decreased. An air speed sensor is installed at the air outlet of the indoor unit of the air conditioner. The air conditioner's processor communicates with the air speed sensor to obtain the actual airflow velocity V1. Based on the actual airflow velocity, the adjustment requirements for air conditioner operation are determined. That is, it is determined whether the air conditioner's operating efficiency has decreased; if it has decreased, adjustment is needed. If it has not decreased, no adjustment is required.

[0032] If adjustment is required, the current operating status of the air conditioner is obtained, such as the operating mode and the temperature of the indoor coil. The target temperature of the indoor coil is determined based on the operating status. The compressor frequency and / or the opening degree of relevant valves are increased. Increasing the compressor frequency changes the refrigerant temperature. The relevant valves are those that can change the refrigerant flow rate into the indoor heat exchanger. Optionally, the relevant valves include a solenoid valve and a throttle valve located at the inlet of the indoor heat exchanger. Increasing the opening degree of the relevant valves increases the refrigerant flow rate into the indoor heat exchanger. Thus, the increase in refrigerant temperature and / or the increase in refrigerant flowing into the indoor heat exchanger causes the indoor coil temperature to reach the target temperature, thereby ensuring the air conditioner's operating efficiency.

[0033] The method for controlling an air conditioner provided in this disclosure first obtains the actual air outlet speed of the air conditioner. Air outlet speed characterizes the air volume. When it is determined based on the air outlet speed that the air conditioner's operating efficiency has decreased, indicating a need to adjust the air conditioner's operation, the main reason is the reduced air volume. In this case, based on the current operating state of the air conditioner, the target temperature of the indoor coil is determined. By controlling the compressor frequency and / or increasing the opening of relevant valves, the temperature of the indoor coil reaches the target temperature, thereby changing the outlet air temperature of the indoor unit to quickly bring the indoor ambient temperature to the user's needs. Thus, by adjusting the temperature of the indoor coil, i.e., adjusting the outlet air temperature, the temperature loss caused by the reduced air volume is compensated for, thereby ensuring the air conditioner's operating efficiency.

[0034] Combination Figure 2 As shown in the embodiments of this disclosure, another method for controlling an air conditioner is provided, including:

[0035] S101, the air conditioner obtains its actual airflow speed.

[0036] S112 is the ratio of the actual air outlet velocity to the theoretical air outlet velocity calculated by the air conditioner.

[0037] S122, when the air conditioner's fan speed ratio is less than the preset ratio, the adjustment requirement for its operation is determined to be that adjustment is needed.

[0038] S132. When the air speed ratio of the air conditioner is greater than or equal to the preset ratio, it is determined that the adjustment requirement for its operation is no adjustment.

[0039] S103. When the adjustment requirement of the air conditioner is that adjustment is needed, according to its current operating state, the target temperature of the internal coil is determined.

[0040] S104. The air conditioner controls the frequency of the compressor and / or the opening degree of the relevant valve body to increase, so that the temperature of the internal coil reaches the target temperature.

[0041] First, determine the current theoretical air outlet speed. Optionally, the relationship between the theoretical air outlet speed and the air volume file is pre-stored in the processor of the air conditioner. According to this relationship, the theoretical air outlet speed corresponding to the current air volume file is determined. Optionally, the air volume files include: silent file, air supply file, low wind file, medium wind file, high wind file and strong wind file. Different air volume files correspond to different theoretical air outlet speeds. The higher the air volume file, the greater the motor speed and the greater the theoretical air outlet speed. Taking a 1.5-horsepower air conditioner as an example, the specific relationship can be referred to Table 1.

[0042] Table 1 Relationship between theoretical air outlet speed and air volume file

[0043] windshield Theoretical air outlet velocity V (m / s) powerful windshield 2.77 High windshield 2.53 Stroke 2.16 Low fan speed 1.94 air supply 1.68 mute 1.32

[0044] Then calculate the ratio N (N = V1 / V) of the actual air outlet speed V1 to the theoretical air outlet speed V, and define the ratio N as the air speed ratio. The preset ratio N' is pre-stored in the processor of the air conditioner. Compare the sizes of N and N'. If N < N', it means that under the current working conditions, the operation of the air conditioner cannot ensure the corresponding working efficiency in the current working mode, and the working conditions of the air conditioner need to be adjusted. If N ≥ N', it means that under the current working conditions, the operation of the air conditioner meets the theoretical design requirements and the operation of the air conditioner does not need to be adjusted. Optionally, N' takes the value of 1. The air speed ratio can characterize whether the actual air outlet speed deviates from the theoretical air outlet speed. Therefore, it can be determined whether the current operation of the air conditioner needs to be adjusted based on the air speed ratio.

[0045] Combined with Figure 3 As shown, another method for controlling an air conditioner provided by an embodiment of the present disclosure includes:

[0046] S101. The air conditioner obtains its actual air outlet speed.

[0047] S102. The air conditioner determines its operation adjustment requirement according to the actual air outlet speed.

[0048] S113. The air conditioner determines the temperature correction value according to its operation mode and air speed ratio.

[0049] S123, the air conditioner determines the target temperature of the inner coil based on the current temperature and temperature correction value of the inner coil.

[0050] S104, the frequency of the air conditioning control compressor and / or the opening degree of the relevant valve body are increased so that the temperature of the inner coil reaches the target temperature.

[0051] The current operating status of the air conditioner includes: the operating mode, the current temperature of the indoor coil, and the fan speed ratio. The operating modes include heating mode and cooling mode. A temperature sensor is installed on the indoor coil. The air conditioner's processor communicates with the temperature sensor to obtain the current temperature of the indoor coil. The fan speed ratio can be calculated using the method described earlier.

[0052] The temperature correction value is determined based on the air conditioner's operating mode and fan speed ratio. The operating mode determines whether a positive or negative correction is applied to the current temperature of the indoor coil. If the operating mode is heating, increasing the indoor coil temperature is necessary to ensure the air conditioner's efficiency; therefore, a positive correction is required. Conversely, if the operating mode is cooling, a negative correction is required. The fan speed ratio determines the degree of correction for the current temperature of the indoor coil. Optionally, the sum of the current temperature of the indoor coil and the temperature correction value is determined as the target temperature for the indoor coil.

[0053] Optionally, if the operating mode is heating mode, the temperature correction value is t1*v1 / v, and the target temperature is t1*(1+v1 / v). If the operating mode is cooling mode, the temperature correction value is -t1*v1 / v, and the target temperature is t1*(1-v1 / v). Where t1 is the current temperature of the inner coil.

[0054] In this way, the temperature correction value is determined based on the air conditioner's operating mode and fan speed ratio, and then the current temperature of the inner coil is corrected to compensate for the temperature loss caused by the reduction in air volume by adjusting the temperature of the inner coil.

[0055] Combination Figure 4 As shown in the embodiments of this disclosure, another method for controlling an air conditioner is provided, including:

[0056] S101, the air conditioner obtains its actual airflow speed.

[0057] S102, the air conditioner determines its operating adjustment requirements based on the actual airflow speed.

[0058] S103, when the air conditioner requires adjustment, it determines the target temperature of the indoor coil based on its current operating status.

[0059] S114, the air conditioner determines the first target adjustment parameter based on the indoor humidity and the air conditioner's operating mode; wherein, the first target adjustment parameter is the compressor frequency or the opening degree of the relevant valve body.

[0060] S124, the first target adjustment parameter of the air conditioning control is increased to the corresponding target value.

[0061] S134, the air conditioner controls the compressor frequency and the opening degree of relevant valves according to the temperature change of the inner coil.

[0062] As mentioned earlier, to achieve the target temperature for the indoor coil, the compressor frequency, the opening of relevant valves, or both can be adjusted. Adjusting the compressor frequency aims to regulate the refrigerant temperature. Regulating the valve opening aims to regulate the refrigerant flow rate into the indoor heat exchanger. Since the objects being regulated differ, the refrigerant parameters (temperature or flow rate) will also be adjusted differently. Furthermore, adjusting different refrigerant parameters will affect the rate at which the indoor heat exchanger temperature is adjusted. Therefore, after determining the target temperature for the indoor coil, the first target adjustment parameter is determined based on the indoor humidity and the air conditioner's operating mode. Here, the first target adjustment parameter is the parameter that is adjusted first. After the first target adjustment parameter is adjusted, the secondary target adjustment parameter is considered based on the temperature change of the indoor coil. For example, if the compressor frequency is adjusted first, and then the valve opening is adjusted, the compressor frequency is the first target adjustment parameter, and the valve opening is the secondary target adjustment parameter. Similarly, if the valve opening is adjusted first, and then the compressor frequency is adjusted, the valve opening is the first target adjustment parameter, and the compressor frequency is the secondary target adjustment parameter.

[0063] The compressor frequency and valve opening each correspond to different target values. First, the initial target adjustment parameter is increased to its corresponding target value to initially regulate the temperature of the inner coil. Then, based on the temperature changes of the inner coil, it is determined whether the temperature has reached the target temperature. This determines whether further adjustment of the compressor frequency and related valve openings is necessary, thus enabling relevant control of the compressor frequency and valve openings. This ensures that the inner coil temperature reaches the target temperature, thereby guaranteeing the air conditioner's operating efficiency.

[0064] Optionally, in step S114, the air conditioner determines the first target adjustment parameter based on the indoor humidity and the air conditioner's operating mode, including:

[0065] When the indoor humidity is greater than the humidity threshold, if the air conditioner is in heating mode, the first target adjustment parameter is determined to be the compressor frequency; if the air conditioner is in cooling mode, the first target adjustment parameter is determined to be the opening degree of the relevant valve.

[0066] When the indoor humidity is less than or equal to the humidity threshold, if the air conditioner is in heating mode, the first target adjustment parameter is the opening degree of the relevant valve body; if the air conditioner is in cooling mode, the first target adjustment parameter is the compressor frequency.

[0067] The air conditioner's processor communicates with a humidity sensor located indoors to obtain the indoor humidity H. Simultaneously, the processor pre-stores a humidity threshold H'. The values ​​of H and H' are compared.

[0068] When H>H', if the air conditioner is operating in heating mode, the first target adjustment parameter is determined to be the compressor frequency. This is because the humidity is high at this time, the specific heat capacity of the refrigerant is high, and the energy saturation value per unit area of ​​the inner coil is high, thus requiring more energy. Prioritizing the adjustment of the compressor frequency can meet the high energy demand and adjust the temperature of the inner coil more quickly.

[0069] When H>H', if the air conditioner is running in cooling mode, the first target adjustment parameter is determined to be the opening degree of the relevant valve. This is because the humidity is high at this time; if the frequency is increased first, a large amount of condensation will be generated, which will have a significant impact on cooling.

[0070] When H ≤ H', if the air conditioner is operating in heating mode, the first target adjustment parameter is determined to be the opening degree of the relevant valve. This is because the humidity is low at this time, meaning the indoor environment is relatively dry. In a dry state, the rate at which hot air rises is greater than the rate of heat conduction. Therefore, the opening degree of the relevant valve is adjusted first to increase the refrigerant flow rate into the indoor heat exchanger.

[0071] When H ≤ H', if the air conditioner is running in cooling mode, the first target adjustment parameter is determined to be the compressor frequency. This is because the humidity is low at this time, and the cooling temperature is more uniform. To quickly meet the user's needs, the frequency is prioritized for adjustment.

[0072] In this way, by combining the indoor humidity level with the air conditioner's operating mode, the parameters to be prioritized for adjustment are selected to quickly regulate the temperature of the indoor coil, thereby ensuring the air conditioner's efficiency and meeting user needs. This also avoids the effects of condensation that may occur when adjusting the first target parameter.

[0073] Optionally, in step S134, the air conditioner controls the compressor frequency and the opening degree of relevant valves based on the temperature change of the indoor coil, including:

[0074] If the internal coil temperature reaches the target temperature while the air conditioner is increasing the first target adjustment parameter to the corresponding target value or when the target value is reached, the first target adjustment parameter and the second target adjustment parameter will be kept in their current state.

[0075] If the temperature of the indoor coil is lower than the target temperature after the first target adjustment parameter of the air conditioner is increased to the corresponding target value, the first target adjustment parameter and the second target adjustment parameter will be adjusted alternately.

[0076] The secondary target adjustment parameter is the compressor frequency or the opening degree of the relevant valve body, and it is different from the primary target adjustment parameter.

[0077] After the first target adjustment parameter is adjusted, the next parameter to be adjusted is the secondary target adjustment parameter. The first target adjustment parameter and the secondary target adjustment parameter are different, but both can be one of the compressor frequency and the opening degree of the relevant valve body.

[0078] When the first target adjustment parameter is increased to the corresponding target value, and during the process of increasing the first target adjustment parameter to the corresponding target value, if the temperature of the inner coil reaches the target temperature, the first target adjustment parameter is kept at its current value. At the same time, the second target adjustment parameter is kept at its current value, that is, the second target adjustment parameter is no longer adjusted.

[0079] When the first target adjustment parameter is increased to the corresponding target value, if the temperature of the inner coil does not reach the target temperature, the first and second target adjustment parameters are adjusted alternately until the temperature of the inner coil reaches the target temperature. Then, the first and second target adjustment parameters are kept at their current values. When adjusting the target adjustment parameters alternately, the other target adjustment parameter is kept constant while adjusting one.

[0080] Optionally, if the target adjustment parameter is the compressor frequency, then each time the frequency is increased, the control frequency is increased by a first amplitude. Optionally, the first amplitude is the frequency difference between the compressor frequency corresponding to the current fan speed and the compressor frequency corresponding to the fan speed one level higher. For example, if the current fan speed is low, the corresponding frequency is f. The fan speed one level higher is medium, and the frequency corresponding to medium is f'. Then the first amplitude is f'-f, that is, the compressor frequency is increased to the compressor frequency corresponding to medium.

[0081] Optionally, each time the control frequency is increased by a first increment, the frequency increase rate is controlled according to the temperature change rate of the inner coil. The larger the temperature change rate Vt of the inner coil, the smaller the frequency increase rate Vf. Optionally, the temperature change rate of the inner coil and the frequency increase rate are correlated and pre-stored in the air conditioner's processor. This correlation includes a correspondence between the temperature change rate of one or more inner coils and the frequency increase rate. Specific correspondences can be found in Table 2.

[0082] Table 2. Relationship between the rate of temperature change of the internal coil and the rate of frequency increase.

[0083] The rate of temperature change Vt (°C / s) of the internal coil The upsampling rate Vf (Hz / s) Vt<Vt1 Vf1 Vt1≤Vt<Vt2 Vf2 Vt2≤Vt<Vt3 Vf3 Vt3≤Vt Vf4

[0084] In Table 2, Vt1 is the first preset rate, Vt2 is the second preset rate, Vt3 is the third preset rate, and Vt1 < Vt2 < Vt3. Vf1 is the first frequency increase rate, Vf2 is the second frequency increase rate, Vf3 is the third frequency increase rate, Vf4 is the fourth frequency increase rate, and Vf1 > Vf2 > Vf3 > Vf4. It should be noted that the corresponding relationships in Table 2 are only examples, and the above corresponding relationships can be divided more meticulously according to actual requirements. In this way, the greater the temperature change rate Vt of the inner coil, the smaller the frequency increase rate Vf, so as to avoid overshoot of the frequency.

[0085] Optionally, if the target adjustment parameter is the opening degree of the relevant valve body, then when increasing the valve opening degree each time, the control valve opening degree is increased by the second amplitude. Optionally, the relevant valve body includes one or more valves. When synchronously adjusting each valve, the increase amplitude of each valve is the same. Optionally, the second amplitude is a preset ratio of the current opening degree of the valve. Optionally, the preset ratio is 20% - 25%, for example, 22.5%.

[0086] Optionally, when increasing the control valve opening degree by the second amplitude each time, the increase rate of the opening degree is controlled according to the temperature change rate of the inner coil. The greater the temperature change rate Vt of the inner coil, the smaller the increase rate Vk of the valve opening degree. Optionally, there is an association relationship between the temperature change rate of the inner coil and the increase rate of the valve opening degree, and it is pre - stored in the processor of the air conditioner. This association relationship includes one or more corresponding relationships between the temperature change rate of the inner coil and the increase rate of the valve opening degree. The specific corresponding relationships can be seen in Table 3.

[0087] Table 3 Association relationship between the temperature change rate of the inner coil and the increase rate of the valve opening degree

[0088] The rate of temperature change Vt (°C / s) of the internal coil The rate at which the valve opening increases, Vk (steps / s). Vt<Vt1 Vk1 Vt1≤Vt<Vt2 Vk2 Vt2≤Vt<Vt3 Vk3 Vt3≤Vt Vk4

[0089] In Table 3, Vt1 is the first preset rate, Vt2 is the second preset rate, Vt3 is the third preset rate, and Vt1 < Vt2 < Vt3. Vk1 is the first opening degree increase rate, Vk2 is the second opening degree increase rate, Vk3 is the third opening degree increase rate, Vk4 is the fourth opening degree increase rate, and Vk1 > Vk2 > Vk3 > Vk4. It should be noted that the corresponding relationships in Table 3 are only examples, and the above corresponding relationships can be divided more meticulously according to actual requirements. In this way, the greater the temperature change rate Vt of the inner coil, the smaller the increase rate Vk of the valve opening degree, so as to avoid overshoot of the valve opening degree.

[0090] Specifically, when V1 / V < 1, it is necessary to compensate the heat exchange efficiency of the air conditioner.

[0091] Scenario 1: The first target adjustment parameter is determined to be the compressor frequency. In this case, the compressor frequency is immediately increased. The control frequency is increased from the frequency f1 corresponding to the current fan speed setting to the frequency f2 corresponding to the next higher fan speed setting. During the frequency increase process, the temperature change of the inner coil is monitored. If the temperature of the inner coil reaches the target temperature during the frequency increase process, the frequency increase stops.

[0092] If the frequency increases to f2 but the coil temperature does not reach the target temperature, the compressor maintains the current frequency f2. Simultaneously, the opening of the solenoid valve and throttle valve is adjusted, with the opening increase being 22.5% of the current valve opening. Generally, both are opened simultaneously.

[0093] During valve opening adjustment, the temperature change of the inner coil is monitored. If the inner coil temperature reaches the target temperature during adjustment, the solenoid valve and throttle valve are controlled to maintain their current opening. If the inner coil temperature still does not reach the target temperature after the current opening adjustment is completed, the compressor frequency is further increased to the frequency f3 corresponding to the next higher fan speed.

[0094] This cycle continues until the temperature of the inner coil reaches the target temperature, while the control frequency and valve opening remain unchanged.

[0095] Scenario 2: The first target adjustment parameter is determined to be the opening degree of the relevant valve. In this case, the opening degree of the solenoid valve and throttle valve is increased immediately. The increase in opening degree is 22.5% of the current valve opening degree. During the increase in opening degree, the temperature change of the inner coil is monitored. If the temperature of the inner coil reaches the target temperature during the increase in opening degree, the increase in opening degree stops.

[0096] If the coil temperature does not reach the target temperature when the opening degree increases by 22.5%, the control valve opening degree will remain unchanged. At the same time, the compressor frequency will be increased from the frequency f1 corresponding to the current fan speed to the frequency f2 corresponding to the next higher fan speed.

[0097] During the frequency increase process, the temperature change of the inner coil is monitored. If the inner coil temperature reaches the target temperature during the frequency increase, the compressor is controlled to maintain the current frequency. If the inner coil temperature still does not reach the target temperature after the frequency increase is completed, the valve opening is further increased by 22.5% of the current valve opening.

[0098] This cycle continues until the temperature of the inner coil reaches the target temperature, while the control frequency and valve opening remain unchanged.

[0099] Combination Figure 5As shown, this embodiment of the present disclosure provides a device 50 for controlling an air conditioner, including an acquisition module 51, a first determination module 52, a second determination module 53, and a control module 54. The acquisition module 51 is configured to acquire the actual airflow speed of the air conditioner. The first determination module 52 is configured to determine the adjustment requirements for air conditioner operation based on the actual airflow speed.

The control module 54 is configured to increase the frequency of the compressor and / or the opening degree of related valves to bring the temperature of the inner coil to the target temperature.

[0100] Using the air conditioning control apparatus provided in this disclosure, the actual air outlet speed of the air conditioner is first obtained. Air outlet speed characterizes the air volume. When it is determined based on the air outlet speed that the air conditioner's operating efficiency has decreased, i.e., adjustment of the air conditioner's operation is required, the main reason being the reduced air volume. In this case, based on the current operating state of the air conditioner, the target temperature of the indoor coil is determined. By controlling the compressor frequency and / or increasing the opening of relevant valves, the temperature of the indoor coil reaches the target temperature, thereby changing the air outlet temperature of the indoor unit to quickly bring the indoor ambient temperature to the user's needs. Thus, by adjusting the temperature of the indoor coil, i.e., adjusting the air outlet temperature, the temperature loss caused by the reduced air volume is compensated, thereby ensuring the air conditioner's operating efficiency.
