Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of intelligent control, and in particular, to a control method and device of an air supply equipment, an air conditioning equipment, and a storage medium. BACKGROUND

[0002] Air supply equipment such as ducted air conditioners, air conditioners, and the like, due to factors such as use form and installation environment, sometimes need to have a fresh air duct, an exhaust air duct, or install a duct at an air inlet / outlet. However, the duct can hinder the free flow of air flow, affect the air supply static pressure, and thus cause the air speed / air volume to decrease, affecting the working performance of the equipment and the experience of the user.

[0003] For example, when the air volume of a ducted air conditioner decreases, it means that the system cannot effectively dissipate heat in the heating mode. This can cause the indoor compressor to work for a longer time, and the equipment to run overloaded for a long time, which can cause equipment failure, increased energy consumption, or shortened service life.

[0004] Therefore, for air supply equipment, how to improve the stability of the air supply volume is a problem that needs to be solved at present. SUMMARY

[0005] The present disclosure aims to at least partially solve one of the technical problems in the related art.

[0006] A control method of an air supply equipment is provided in the first aspect of the present disclosure, comprising:

[0007] obtaining an air inlet temperature and an air outlet temperature of a duct under a current working condition;

[0008] determining a first temperature difference between the air inlet temperature and the air outlet temperature;

[0009] obtaining a second temperature difference corresponding to the current working condition based on a factory parameter of the duct;

[0010] correcting a working parameter of a compressor in the air supply equipment based on a size relationship between the first temperature difference and the second temperature difference.

[0011] A control device of an air supply equipment is provided in the second aspect of the present disclosure, comprising:

[0012] a first obtaining module configured to obtain an air inlet temperature and an air outlet temperature of a duct under a current working condition;

[0013] a first determining module configured to determine a first temperature difference between the air inlet temperature and the air outlet temperature;

[0014] a second determining module configured to obtain a second temperature difference corresponding to the current working condition based on a factory parameter of the duct;

[0015] The first correction module is configured to correct a working parameter of the compressor in the air supply device based on a size relationship between the first temperature difference and the second temperature difference.

[0016] The third aspect of the present disclosure provides an air conditioning device, comprising a memory, a processor and a computer program stored in the memory and executable on the processor, and when the processor executes the program, the control method of the air supply device according to the first aspect of the present disclosure is implemented.

[0017] The fourth aspect of the present disclosure provides a non-transitory computer readable storage medium, which stores a computer program, and when the computer program is executed by a processor, the control method of the air supply device according to the first aspect of the present disclosure is implemented.

[0018] The control method of the air supply device, the device, the air conditioning device and the storage medium provided by the present disclosure have the following beneficial effects:

[0019] In the embodiments of the present disclosure, the inlet temperature and the outlet temperature of the air duct under the current working condition are first obtained, and then the first temperature difference between the inlet temperature and the outlet temperature is determined. Then, based on the factory parameters of the air duct, the second temperature difference corresponding to the current working condition is obtained. Finally, based on the size relationship between the first temperature difference and the second temperature difference, the working parameter of the compressor in the air supply device is corrected. Thus, the second temperature difference when the air supply device is in the best air supply state is determined by the factory parameters of the air duct and the current working condition. Then, by comparing the size relationship between the first temperature difference and the second temperature difference, the working parameter of the compressor is corrected. By changing the working state of the compressor, the fan speed is affected, so that the fan can be at the best speed, ensuring the stable and reliable operation of the system, avoiding the problems of overloading of the indoor unit during heating, freezing and frequency reduction during cooling, shutdown or water blowing caused by reduced air volume, and improving the user experience.

[0020] The additional aspects and advantages of the present disclosure will be partially given in the following description, partially will become obvious from the following description, or will be understood by practicing the present disclosure. BRIEF DESCRIPTION OF DRAWINGS

[0026] Embodiments of the present disclosure are described in detail below with reference to the accompanying drawings, in which like or similar elements or elements having the same or similar functions are denoted by the same or similar reference numerals throughout the drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present disclosure, and should not be construed as limiting the present disclosure.

[0027] A control method, device, air conditioning device, and storage medium of an air supply device of an embodiment of the present disclosure are described below with reference to the accompanying drawings.

[0028] It should be noted that the execution subject of the control method of the air supply device in the embodiments of the present disclosure is a control device of the air supply device, which can be implemented in software and / or hardware, and can be configured in any air conditioning device, such as a ducted air conditioner, a wind-cooled central air conditioner, a fresh air conditioner / module, a mobile air conditioner, etc., which is not limited herein. The control method of the air supply device provided by the embodiments of the present disclosure is described below with the air supply device as the execution subject.

[0029] Figure 1 A flowchart of the control method of the air supply device provided by the first embodiment of the present disclosure is shown.

[0030] As shown in Figure 1 the control method of the air supply device can include the following steps:

[0031] Step 101: Obtain the inlet temperature and outlet temperature of the duct under the current working condition.

[0032] The working condition can include a wind speed gear, and the air supply device has different wind speed intensities under different wind speed gears. For example, the wind speed gear can have a low wind speed gear, a medium wind speed gear, or a high wind speed gear, which is not limited herein.

[0033] In addition, the working condition can also include a working mode of the air supply device during the air supply operation, and a target temperature set in the working mode. The working mode can be a cooling mode, a heating mode, a fresh air mode, a dehumidification mode, or an automatic mode, which is not limited herein.

[0034] The above-mentioned working modes are described illustratively below, but are not limited to the present disclosure.

[0035] Taking an air supply device as an example, when the air conditioning system is in a cooling mode, the indoor unit can send cold air into the room through the fan to lower the indoor temperature. When the air conditioning system is in a heating mode, the indoor unit can send hot air into the room through the fan to raise the indoor temperature.

[0036] The fresh air mode of the air conditioning system is mainly used to provide circulation of indoor air and entry of fresh air. In the fresh air mode, the indoor unit introduces air from the outdoor into the indoor through the fan to realize circulation of air.

[0037] The dehumidification mode of the air conditioning system is mainly used to reduce indoor humidity in a humid environment. In the dehumidification mode, the indoor unit re-sends the air after being treated to absorb moisture into the indoor.

[0038] The automatic mode of the air conditioning system is mainly used to automatically adjust the cooling or heating mode according to the indoor temperature and the set target temperature. When the indoor temperature reaches the set target temperature, the air conditioning system will automatically switch to the fresh air mode or turn off the air supply.

[0039] The air duct can be an air duct (such as a fresh air duct or an exhaust air duct) provided by the air supply device, or an air duct installed on the air inlet / outlet of the air supply device, which is not limited here.

[0040] The air inlet temperature can be the temperature of the air detected at the air inlet position of the air duct.

[0041] The air outlet temperature can be the temperature of the air detected at the air outlet position of the air duct.

[0042] Optionally, the air inlet temperature and the air outlet temperature can be measured by temperature sensors respectively arranged at the air inlet position and the air outlet position of the air duct.

[0043] It can be understood that the air inlet temperature and the air outlet temperature of the air duct can be different under different working conditions of the air supply device. Considering the difference, the embodiments of the present disclosure can adopt a corresponding adjustment and control mechanism according to the type of the working condition of the air supply device.

[0044] Step 102, determining a first temperature difference between the air inlet temperature and the air outlet temperature.

[0045] The first temperature difference can be the temperature difference obtained by subtracting the air outlet temperature from the air inlet temperature, or the temperature difference obtained by subtracting the air inlet temperature from the air outlet temperature, or the absolute value of the temperature difference between the air inlet temperature and the air outlet temperature, which is not limited here.

[0046] For example, if T1inlet represents the inlet temperature, T2outlet represents the outlet temperature, and ΔT1 represents the first temperature difference, the following calculation methods can be used: ΔT1 = T1inlet - T1outlet, or ΔT1 = T1outlet - T1inlet, or ΔT1 = |T1inlet - T1outlet|, without limitation.

[0047] In step 103, based on the air duct factory parameter, a second temperature difference corresponding to the current working condition is obtained.

[0048] The second temperature difference can be a reference temperature difference. By comparing the difference between the first temperature difference and the second temperature difference, the air supply device can determine whether the air supply through the air duct is in an optimal air supply state. If the difference between the first temperature difference and the second temperature difference is smaller, it means that the current air supply amount of the air duct is more reliable, more in line with expectations, and the air supply state is better.

[0049] In determining the second temperature difference, both the air duct factory parameter and the current working condition of the air supply device can be considered.

[0050] As a possible implementation, the first set air speed and the first set temperature corresponding to the current working condition of the air supply device can be determined first, and then based on the air duct factory parameter, a first mapping relationship corresponding to the air duct length can be determined. Then, based on the first mapping relationship, a target air duct inlet and outlet temperature difference corresponding to the first set air speed and the first set temperature can be determined, and then the target air duct inlet and outlet temperature difference can be determined as the second temperature difference.

[0051] The first set air speed and the first set temperature can be the set air speed and temperature of the air supply device in the current working condition.

[0052] For example, if the air supply device is an air conditioner, the current working condition is a cooling mode, the set air speed is a medium speed, and the set temperature is 19°C, 19°C can be used as the first set temperature corresponding to the current air conditioner. The air speed V corresponding to the medium speed can be used as the first set air speed, without limitation.

[0053] The air duct factory parameter can include attribute information of the air duct, such as the diameter, shape, cross-sectional area, material, and first mapping relationship corresponding to each air duct length (or first mapping relationship corresponding to unit length), without limitation.

[0054] The first mapping relationship is used to record the air duct inlet and outlet temperature difference corresponding to different set air speeds and set temperatures.

[0055] It should be noted that for different types of air ducts, the diameter, cross-sectional area and shape, material may be different, so that the temperature difference between the inlet and outlet of the unit length of the air duct may also be different when the air of a certain wind speed and a certain temperature is introduced.

[0056] For example, if the length of air duct A and air duct B is 1m, the diameter, cross-sectional area and shape, material of air duct A are different from those of air duct B, so that when the air of wind speed V1 and temperature T1 is introduced into the air inlet of air duct A and air duct B, the air speed of the air outlet of air duct A is V2 and the temperature is T2, and the air speed of the air outlet of air duct B is V3 and the temperature is T3, that is, the air speed and temperature of the outlet of air duct A and air duct B with the same length may be different when the same temperature and wind speed are introduced, which is not limited here.

[0057] Therefore, the first mapping relationship corresponding to each length of the air duct can be recorded in advance, that is, the air duct inlet and outlet temperature difference corresponding to different set wind speed and set temperature of each length of the air duct.

[0058] The air duct inlet and outlet temperature difference can be the temperature difference between the air inlet temperature and the air outlet temperature of the air duct, which can be the temperature difference obtained by subtracting the air outlet temperature from the air inlet temperature, or the temperature difference obtained by subtracting the air inlet temperature from the air outlet temperature, or the absolute value of the temperature difference between the air inlet temperature and the air outlet temperature, which is not limited here.

[0059] The set wind speed and the set temperature are respectively the wind speed and the temperature corresponding to any working condition of the air supply device.

[0060] For example, the air duct inlet and outlet temperature difference corresponding to different set wind speed and set temperature of unit length of air duct A can be recorded in advance, so that the corresponding air duct inlet and outlet temperature difference AT can be directly obtained when air duct A is introduced into the air inlet with a set wind speed of V1 and a set temperature of T1.

[0061] It should be noted that the first mapping relationship corresponding to different lengths of the air duct can be different, so that the first mapping relationship corresponding to different lengths of the air duct can be stored in advance.

[0062] The following table can be a schematic table of a first mapping relationship:

[0063] Serial number Length of air duct L Set air speed V Set temperature T Temperature difference of air duct inlet and outlet ΔT 1 L1 V1 T2 △T1 2 L1 V2 T1 △T2 3 L1 V1 T1 △T3 4 L2 V1 T2 △T4 5 L2 V2 T1 △T5 6 L2 V1 T1 △T6

[0064] The serial numbers 1, 2 and 3 are the first mapping relationship corresponding to the length L1 of the air duct, which includes the air duct inlet and outlet temperature difference AT corresponding to different set wind speed V and set temperature T, and the serial numbers 4, 5 and 6 are the first mapping relationship corresponding to the length L2 of the air duct.

[0065] The target air pipe inlet and outlet temperature difference can be an air pipe inlet and outlet temperature difference corresponding to the first set air speed and the first set temperature.

[0066] For example, for an air pipe with a length of L1, the first set air speed is V1, the first set temperature is T2, and the corresponding target air pipe inlet and outlet temperature difference is AT1. Then, the target air pipe inlet and outlet temperature difference AT1 can be used as the second temperature difference.

[0067] It should be noted that the above examples are only illustrative of the step and do not limit the present disclosure.

[0068] In step 104, the working parameters of the compressor in the air supply device are corrected based on the size relationship between the first temperature difference and the second temperature difference.

[0069] The working parameters can be frequency, power, speed, compression ratio, without limitation.

[0070] Optionally, if the working parameter is the frequency of the compressor, a first difference value between the first temperature difference and the second temperature difference can be determined first. Then, based on a preset second mapping relationship, a frequency correction amount associated with the first difference value can be determined. If the first temperature difference is less than the second temperature difference, the current frequency of the compressor is increased based on the frequency correction amount. If the first temperature difference is greater than the second temperature difference, the current frequency of the compressor is decreased based on the frequency correction amount.

[0071] The second temperature difference can correspond to the first temperature difference. If the first temperature difference is the temperature difference obtained by subtracting the outlet temperature from the inlet temperature, the second temperature difference is also the temperature difference obtained by subtracting the outlet temperature from the inlet temperature.

[0072] If the first temperature difference is the temperature difference obtained by subtracting the inlet temperature from the outlet temperature, the second temperature difference is also the temperature difference obtained by subtracting the inlet temperature from the outlet temperature.

[0073] Alternatively, if the first temperature difference is the absolute value of the temperature difference between the inlet temperature and the outlet temperature, the second temperature difference is also the absolute value of the temperature difference between the inlet temperature and the outlet temperature, without limitation.

[0074] The first difference value can be the difference between the first temperature difference and the second temperature difference, which can be positive, negative, or zero.

[0075] The second mapping relationship can record the frequency correction amount corresponding to each first difference value.

[0076] For example, if the frequency correction amount corresponding to the first difference 'a' is 'b', and the first temperature difference is less than the second temperature difference, it means that the temperature difference has decreased by 'a'℃, and the compressor frequency needs to be increased by 'b'Hz.

[0077] For example, if the frequency correction amount corresponding to the first difference of -1 is 2, and the first temperature difference is less than the second temperature difference, it means that the first temperature difference has decreased by 1℃, and the compressor frequency needs to be increased by 2Hz accordingly.

[0078] If the frequency correction amount corresponding to the first difference a is b, and the first temperature difference is greater than the second temperature difference, it means that the temperature difference has increased by a℃, and the compressor frequency needs to be reduced by bHz.

[0079] For example, if the frequency correction amount corresponding to the first difference of 1 is 2, and the first temperature difference is greater than the second temperature difference, it means that the first temperature difference has increased by 1℃, and the compressor frequency needs to be reduced by 2Hz accordingly.

[0080] Optionally, if the first temperature difference is equal to the second temperature difference, then it is not necessary to correct the compressor's operating parameters.

[0081] It's important to note that increasing the compressor frequency also increases the fan speed, providing more cooling or heat transfer. This increases the airflow and velocity produced by the fan, effectively altering indoor air circulation and temperature distribution. The increased compressor frequency can be adjusted by regulating the fan speed through the control system to regulate airflow. Higher compressor frequencies may require higher airflow to meet the increased demand; therefore, the system automatically adjusts the fan speed to match the required airflow, thus preventing problems such as indoor unit overload during heating, frequency throttling during cooling to prevent freezing, shutdown, or water flushing caused by reduced airflow.

[0082] Increasing the compressor frequency is usually accompanied by an increase in cooling load, which leads to more refrigerant flowing through the evaporator. To meet the higher cooling demands, the system may correspondingly increase the fan speed or adjust the damper opening, thereby increasing the airflow. This allows the airflow to be adjusted by changing the compressor frequency.

[0083] Alternatively, if compressor power is used as the operating parameter, the fan power can be increased to provide a larger air volume, thus compensating for the loss caused by the duct length. Specifically, the power correction amount corresponding to the first difference can be pre-stored, and the actual fan power can then be adjusted based on the first difference.

[0084] Alternatively, if compressor speed is used as the operating parameter, the fan speed can be increased to provide a larger air volume, thus compensating for the loss caused by the duct length. Specifically, the speed correction amount corresponding to the first difference can be pre-stored, and the fan speed can then be adjusted based on the first difference.

[0085] In the embodiments of the present disclosure, the inlet temperature and the outlet temperature of the air duct under the current working condition are first acquired, then a first temperature difference between the inlet temperature and the outlet temperature is determined, then a second temperature difference corresponding to the current working condition is acquired based on the air duct factory parameter, and finally the working parameter of the compressor in the air supply device is corrected based on the size relationship between the first temperature difference and the second temperature difference. Thus, the second temperature difference when the air supply device is in the best air supply state is determined through the air duct factory parameter and the current working condition, and then the working parameter of the compressor is corrected by comparing the size relationship between the first temperature difference and the second temperature difference, the working state of the compressor is changed to further affect the fan speed, so that the fan can be in the best speed, the stable and reliable operation of the system is ensured, and the problems of overloading of the indoor unit during heating, freezing and frequency reduction of the indoor unit during cooling, shutdown or water blowing caused by the reduction of air volume are avoided, and the user experience is improved.

[0086] Figure 2 A flowchart of a control method of an air supply device provided by a second embodiment of the present disclosure is shown.

[0087] As Figure 2 shown, the control method of the air supply device can include the following steps:

[0088] Step 201, acquiring the inlet temperature and the outlet temperature of the air duct under the current working condition.

[0089] Step 202, determining a first temperature difference between the inlet temperature and the outlet temperature.

[0090] Step 203, acquiring a second temperature difference corresponding to the current working condition based on the air duct factory parameter.

[0091] Step 204, correcting the working parameter of the compressor in the air supply device based on the size relationship between the first temperature difference and the second temperature difference.

[0092] It should be noted that the specific implementation of steps 201-204 can refer to the above embodiments, which will not be described here.

[0093] Step 205, acquiring the outlet air speed of the air duct under the current working condition.

[0094] The outlet air speed can be measured by the air speed detection device arranged at the outlet of the air duct.

[0095] The current working condition can include the set temperature and the set air speed of the air supply device.

[0096] Step 206, calculating the actual air volume of the air supply device according to the outlet air speed and the cross-sectional area of the air duct.

[0097] Optionally, the actual air volume of the air supply device can be calculated by the formula Q=VF.

[0098] wherein Q is the actual air volume, V is the air outlet speed, and F is the cross-sectional area of the air duct.

[0099] In step 207, the reference air volume corresponding to the current working condition is obtained according to the air duct factory parameter.

[0100] As a possible implementation manner, the first set air speed corresponding to the current working condition can be determined first, and then the fourth mapping relationship corresponding to the air duct length is determined.

[0101] The first set air speed can be the air speed of the air supply device running in the current working condition. For example, if the air speed gear of the air supply device running is the medium air speed gear, the first set air speed is V1, which is not limited herein.

[0102] It should be noted that the fourth mapping relationship corresponding to different air duct lengths is different.

[0103] The fourth mapping relationship can be used to record the reference air volume corresponding to different set air speeds.

[0104] The following table is a schematic table of a fourth mapping relationship:

[0105]

[0106]

[0107] The serial numbers 1, 2, and 3 are the fourth mapping relationship corresponding to the air duct length L1, which contains the reference air volume Q corresponding to different set air speeds V. The serial numbers 4, 5, and 6 are the fourth mapping relationship corresponding to the air duct length L2.

[0108] Then, the reference air volume Q corresponding to the first set air speed can be determined based on the fourth mapping relationship.

[0109] For example, for the air duct with the length L1, the first set air speed is V1, and the corresponding reference air volume is Q1.

[0110] It should be noted that the above examples are only a schematic description of this step, and do not constitute a limitation on the present disclosure.

[0111] In step 208, the speed of the air blower is corrected based on the size relationship between the actual air volume and the reference air volume.

[0112] Optionally, a second difference between the actual air volume and the reference air volume can be determined first, and then a speed correction amount associated with the second difference can be determined based on a preset third mapping relationship. If the actual air volume is less than the reference air volume, the current speed of the fan is increased based on the speed correction amount. If the actual air volume is greater than the reference air volume, the current speed of the fan is decreased based on the speed correction amount.

[0113] The second difference can be the air volume difference between the actual air volume and the reference air volume, which can be positive, negative, or 0.

[0114] The third mapping relationship can record the speed correction amount corresponding to each second difference.

[0115] Optionally, if the actual air volume is equal to the reference air volume, the speed of the fan does not need to be corrected.

[0116] The following is a schematic table of a third mapping relationship:

[0117] Actual air volume Q1 / m3 3 ]]> ​ Second difference (Q1-Q2) / m3 Speed correction amount ΔV / rpm 15 45 -30 +20 30 45 -15 +10 45 45 0 0 60 45 15 -10

[0118] As shown in the above table, if the reference air volume is 45m 3 , the actual air volume decreases by 15m 3 , and the speed needs to be increased by 10rpm accordingly.

[0119] It should be noted that the above example is only an illustrative description and does not limit the disclosure.

[0120] In the embodiments of the disclosure, the inlet temperature and the outlet temperature of the air duct under the current working condition are obtained first, and then the first temperature difference between the inlet temperature and the outlet temperature is determined. Then, according to the factory parameters of the air supply device, the second temperature difference corresponding to the current working condition is determined. Then, based on the size relationship between the first temperature difference and the second temperature difference, the working parameters of the compressor in the air supply device are corrected, the outlet air speed of the air duct under the current working condition is obtained, and then the actual air volume of the air supply device is calculated according to the outlet air speed and the cross-sectional area of the air duct. Then, according to the factory parameters of the air duct, the reference air volume corresponding to the current working condition is obtained, and then the speed of the fan is corrected based on the size relationship between the actual air volume and the reference air volume. Thus, the fan speed can be adjusted by detecting the air duct outlet air speed and the air duct temperature, so as to ensure the optimal speed of the system, guarantee the reliability and stability of the system, improve the user experience, and solve the problem that the overall air supply air volume of the product is lower than expected, affecting the user experience of the product.

[0147] if the actual air volume is greater than the reference air volume, decrease the current rotation speed of the air blower based on the rotation speed correction amount.
