Description

Technical Field

[0001] The present disclosure relates to the field of intelligent control technology, and in particular to a control method and device for air supply equipment, air conditioning equipment and a storage medium. Background Art

[0002] Air supply equipment such as duct units and air conditioners, affected by factors such as usage and installation environment, sometimes need to have fresh air ducts, exhaust ducts, or install ducts at the air inlet / outlet. However, ducts may hinder the free flow of air, affect the static pressure of air supply, and thus reduce the wind speed / air volume, affecting the working performance of the equipment and the user experience.

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

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

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

[0006] The first embodiment of the present disclosure provides a control method for an air supply device, comprising:

[0007] Get the air inlet temperature and air outlet temperature of the air duct under the current working conditions;

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

[0009] Based on the factory parameters of the air duct, obtaining a second temperature difference corresponding to the current working condition;

[0010] Based on the magnitude relationship between the first temperature difference and the second temperature difference, the operating parameters of the compressor in the air supply device are corrected.

[0011] The second aspect of the present disclosure provides a control device for air supply equipment, including:

[0012] The first acquisition module is used to obtain the air inlet temperature and the air outlet temperature of the air duct under the 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 determination module, configured to obtain a second temperature difference corresponding to the current working condition based on factory parameters of the air duct;

[0015] The first correction module is used to correct the working parameters of the compressor in the air supply device based on the magnitude relationship between the first temperature difference and the second temperature difference.

[0016] The third aspect embodiment of the present disclosure proposes an air conditioning device, including: a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the program, the control method of the air supply device proposed in the first aspect embodiment of the present disclosure is implemented.

[0017] The fourth aspect embodiment of the present disclosure proposes a non-temporary computer-readable storage medium storing a computer program, which, when executed by a processor, implements the control method of the air supply equipment proposed in the first aspect embodiment of the present disclosure.

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

[0019] In the disclosed embodiment, the air inlet temperature and the air outlet temperature of the air duct under the current working condition are first obtained, and then the first temperature difference between the air inlet temperature and the air 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 magnitude relationship between the first temperature difference and the second temperature difference, the working parameters of the compressor in the air supply device are corrected. Thus, the second temperature difference when the air supply device is in the optimal air supply state is determined by the factory parameters of the air duct and the current working condition, and then the working parameters of the compressor are corrected by comparing the magnitude relationship between the first temperature difference and the second temperature difference. By changing the working state of the compressor and thus affecting the fan speed, the fan can be at the optimal speed, ensuring stable and reliable operation of the system, avoiding problems such as overload of the indoor unit during heating, frequency reduction for anti-freezing of refrigeration, shutdown or water blowing caused by reduced air volume, and improving the user experience.

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

[0027] The following describes a control method, an apparatus, an air conditioning device, and a storage medium for an air supply device according to an embodiment of the present disclosure 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 embodiment of the present disclosure is the control device of the air supply device, which can be implemented by software and / or hardware, and can be configured in any air conditioning equipment, such as a duct machine, an air-cooled central air conditioner, a fresh air air conditioner / module, a mobile air conditioner, etc., which are not limited here. The control method of the air supply device provided in the embodiment of the present disclosure is described below with the air supply device as the execution subject.

[0029] Figure 1 A schematic flow chart of a method for controlling an air supply device provided in the first embodiment of the present disclosure.

[0030] like Figure 1 As shown, the control method of the air supply device may include the following steps:

[0031] Step 101, obtaining the air inlet temperature and the air outlet temperature of the air duct under the current working condition.

[0032] The working condition may include a wind speed level, and the wind speed strength of the air supply device at different wind speed levels is different. For example, the wind speed level may include a low wind speed level, a medium wind speed level, or a high wind speed level, which is not limited here.

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

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

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

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

[0037] The dehumidification mode of the air conditioning system is mainly used to reduce indoor humidity in a humid environment. In dehumidification mode, the indoor unit will process the moisture-absorbed air and send it back into the room.

[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 may be an air duct provided by the air supply device (such as a fresh air duct or an exhaust air duct), 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 may be the air inlet temperature detected at the air duct inlet.

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

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

[0043] It is understandable that the air inlet temperature and the air outlet temperature of the air duct may be different under different working conditions of the air supply device. Considering this difference, the embodiments of the present disclosure may adopt corresponding adjustment and control mechanisms according to the working condition type of the air supply device.

[0044] Step 102: determine a first temperature difference between an air inlet temperature and an air outlet temperature.

[0045] Among them, 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 it can be 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 T1 inlet represents the inlet temperature, T2 outlet represents the outlet temperature, and △T1 is used as the first temperature difference, the following calculation methods can be used: △T1=T1 inlet-T1 outlet, or △T1=T1 outlet-T1 inlet, or △T1=|T1 inlet-T1 outlet|, which is not limited here.

[0047] Step 103: Based on the factory parameters of the air duct, a second temperature difference corresponding to the current working condition is obtained.

[0048] The second temperature difference may be a reference temperature difference. By comparing the difference between the first temperature difference and the second temperature difference, the air supply device may 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 volume of the air duct is more reliable, more in line with expectations, and the air supply state is better.

[0049] When determining the second temperature difference, two factors may be considered: the factory parameters of the air duct and the current working condition of the air supply equipment.

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

[0051] Among them, the first set wind speed and the first set temperature may be the wind speed and temperature set for the air supply equipment under the current working conditions.

[0052] For example, if the air supply device is an air conditioner, the current working condition is cooling mode, the set wind speed gear is a medium wind speed, and the set temperature is 19°C, then 19°C can be used as the first set temperature corresponding to the air conditioner. The wind speed V corresponding to the medium wind speed is used as the first set wind speed, which is not limited here.

[0053] Among them, the factory parameters of the air duct may include attribute information of the air duct, such as the diameter, shape, cross-sectional area, material of the air duct, and the first mapping relationship corresponding to each air duct length (or the first mapping relationship corresponding to the unit length), which is not limited here.

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

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

[0056] For example, if the lengths of air duct A and air duct B are both 1 m, and the diameter, cross-sectional area, cross-sectional shape, and material of air duct A are all different from those of air duct B, then when wind with a wind speed of V1 and a temperature of T1 is introduced into the air inlets of air duct A and air duct B, the wind speed at the air outlet of air duct A is V2 and the temperature is T2, while the wind speed at the air outlet of air duct B may be V3 and the temperature is T3. That is, when air ducts A and B with the same length are introduced with wind of the same temperature and wind speed, there may be differences in the wind speed and temperature at the outlet, which is not limited here.

[0057] Therefore, the first mapping relationship corresponding to the air ducts of various lengths may be recorded in advance, that is, the air duct inlet and outlet temperature differences corresponding to the air ducts of various lengths at different set wind speeds and set temperatures.

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

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

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

[0061] It should be noted that the first mapping relationships corresponding to air ducts of different lengths may be different, and thus the first mapping relationships corresponding to air ducts of different lengths may be pre-stored.

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

[0063] Serial number Duct length L Set wind speed V Set temperature T Duct inlet and outlet temperature difference △T 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] Among them, serial numbers 1, 2, and 3 are the first mapping relationships corresponding to the duct length L1, including the duct inlet and outlet temperature differences △T corresponding to different set wind speeds V and set temperatures T, and serial numbers 4, 5, and 6 are the first mapping relationships corresponding to the duct length L2.

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

[0066] For example, for an air duct with a length of L1, the first set wind speed is V1, the first set temperature is T2, and the corresponding target air duct inlet and outlet temperature difference is △T1. Then, the target air duct inlet and outlet temperature difference △T1 can be used as the second temperature difference.

[0067] It should be noted that the above examples are only illustrative of the steps and do not constitute a limitation to the present disclosure.

[0068] Step 104: based on the magnitude relationship between the first temperature difference and the second temperature difference, correct the operating parameters of the compressor in the air supply device.

[0069] The operating parameters may be frequency, power, rotation speed, compression ratio, which are not limited here.

[0070] Optionally, if the operating parameter is the frequency of the compressor, the first difference between the first temperature difference and the second temperature difference can be first determined, and then the frequency correction associated with the first difference can be determined based on a preset second mapping relationship. If the first temperature difference is smaller than the second temperature difference, the current frequency of the compressor is increased based on the frequency correction. If the first temperature difference is greater than the second temperature difference, the current frequency of the compressor is reduced based on the frequency correction.

[0071] Among them, the second temperature difference can correspond to the first temperature difference. If the first temperature difference is the temperature difference obtained by subtracting the air outlet temperature from the air inlet temperature, then the second temperature difference also corresponds to the temperature difference obtained by subtracting the air outlet temperature from the air inlet temperature.

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

[0073] Alternatively, if the first temperature difference is the absolute value of the temperature difference between the air inlet temperature and the air outlet temperature, then the second temperature difference also corresponds to the absolute value of the temperature difference between the air inlet temperature and the air outlet temperature, which is not limited here.

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

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

[0076] For example, if the frequency correction amount corresponding to the first difference a is b, and the first temperature difference is smaller than the second temperature difference, it means that the temperature difference decreases by a° C., and the frequency of the compressor needs to be increased by b Hz.

[0077] For example, the frequency correction amount corresponding to the first difference value -1 is 2, and the first temperature difference is smaller than the second temperature difference, which means that the first temperature difference decreases by 1°C, and the frequency of the compressor 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°C, and the frequency of the compressor needs to be reduced by bHz.

[0079] For example, the frequency correction amount corresponding to the first difference 1 is 2, and the first temperature difference is greater than the second temperature difference, which means that the first temperature difference increases by 1° C., and the frequency of the compressor needs to be reduced by 2 Hz accordingly.

[0080] Optionally, if the first temperature difference is equal to the second temperature difference, there is no need to correct the operating parameters of the compressor.

[0081] It should be noted that by increasing the frequency of the compressor, the speed of the fan will also increase accordingly to provide more cooling or heat transfer, which can increase the air volume and wind speed generated by the fan, effectively changing the flow and temperature distribution of indoor air. The increase in the frequency of the compressor can adjust the speed of the fan by adjusting the speed of the fan through the control system to adjust the air volume. A higher compressor frequency may require a higher air volume to meet the increased demand, so the system will automatically adjust the fan speed to match the required air volume, thereby avoiding problems such as overload of the indoor unit during heating, frequency reduction for anti-freezing of refrigeration, shutdown or water blowing due to reduced air volume.

[0082] Among them, the increase in compressor frequency is usually accompanied by an increase in refrigeration load, which causes more coolant to flow through the evaporator. In order to meet higher cooling needs, the system may increase the fan speed or adjust the damper opening accordingly to increase the air volume, thereby achieving the effect of changing the compressor frequency to adjust the air volume.

[0083] Alternatively, if the compressor power is used as the working parameter, the fan power can be increased to provide a larger air volume to compensate for the loss caused by the air duct length. Specifically, the power correction amount corresponding to the first difference can be pre-stored, and then the actual power of the fan can be corrected according to the first difference.

[0084] Alternatively, if the compressor speed is used as the working parameter, the fan speed can be increased to provide a larger air volume to compensate for the loss caused by the air duct length. Specifically, the speed correction amount corresponding to the first difference can be pre-stored, and the fan speed can be corrected according to the first difference.

[0085] In the disclosed embodiment, the air inlet temperature and the air outlet temperature of the air duct under the current working condition are first obtained, and then the first temperature difference between the air inlet temperature and the air 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 magnitude relationship between the first temperature difference and the second temperature difference, the working parameters of the compressor in the air supply device are corrected. Thus, the second temperature difference when the air supply device is in the optimal air supply state is determined by the factory parameters of the air duct and the current working condition, and then the working parameters of the compressor are corrected by comparing the magnitude relationship between the first temperature difference and the second temperature difference. By changing the working state of the compressor and thus affecting the fan speed, the fan can be at the optimal speed, ensuring stable and reliable operation of the system, avoiding problems such as overload of the indoor unit during heating, frequency reduction for anti-freezing of refrigeration, shutdown or water blowing caused by reduced air volume, and improving the user experience.

[0086] Figure 2 A schematic flow chart of a method for controlling an air supply device provided in the second embodiment of the present disclosure.

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

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

[0089] Step 202: determine a first temperature difference between the air inlet temperature and the air outlet temperature.

[0090] Step 203: Based on the factory parameters of the air duct, a second temperature difference corresponding to the current working condition is obtained.

[0091] Step 204: based on the magnitude relationship between the first temperature difference and the second temperature difference, correct the operating parameters of the compressor in the air supply device.

[0092] It should be noted that the specific implementation of steps 201 - 204 may refer to the above embodiment and will not be described in detail here.

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

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

[0095] The current working condition may include the current set temperature and set wind speed of the air supply equipment.

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

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

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

[0099] Step 207, obtaining a reference air volume corresponding to the current working condition according to the factory parameters of the air duct.

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

[0101] The first set wind speed may be the wind speed of the air supply device under the current working condition. For example, if the wind speed gear of the air supply device is a medium wind speed gear, the first set wind speed is V1, which is not limited here.

[0102] It should be noted that different air duct lengths correspond to different fourth mapping relationships.

[0103] The fourth mapping relationship may be used to record reference wind volumes corresponding to different set wind speeds.

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

[0105]

[0106]

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

[0108] Afterwards, a reference wind volume Q corresponding to the first set wind speed may be determined based on the fourth mapping relationship.

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

[0110] It should be noted that the above examples are only illustrative of the steps and do not constitute a limitation to the present disclosure.

[0111] Step 208, based on the relationship between the actual air volume and the reference air volume, correct the speed of the fan.

[0112] Optionally, a second difference between the actual air volume and the reference air volume can be determined first, and then a speed correction 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. If the actual air volume is greater than the reference air volume, the current speed of the fan is reduced based on the speed correction.

[0113] The second difference may be an air volume difference between the actual air volume and the reference air volume, which may be a positive value, a negative value, or zero.

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

[0115] Optionally, if the actual air volume is equal to the reference air volume, there is no need to correct the speed of the fan.

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

[0117] Actual air volume Q1 / m3 <![CDATA[Reference air volume Q2 / m 3 > The second difference (Q1-Q2) / m3 Speed ​​correction △V / rpm 15 45 -30 +20 30 45 -15 +10 45 45 0 0 60 45 15 -10

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

[0119] It should be noted that the above examples are only for illustrative purposes and are not intended to limit the present disclosure.

[0120] In the disclosed embodiment, the air inlet temperature and air outlet temperature of the air duct under the current working condition are first obtained, and then the first temperature difference between the air inlet temperature and the air outlet temperature is determined, and then the second temperature difference corresponding to the current working condition is determined based on the factory parameters of the air supply device, and then 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, and the air outlet wind 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 based on the air outlet wind speed and the cross-sectional area of ​​the air duct, and then the reference air volume corresponding to the current working condition is obtained based on the factory parameters of the air duct, and then the speed of the fan is corrected based on the size relationship between the actual air volume and the reference air volume. In this way, the fan speed can be adjusted by detecting the air outlet wind speed and the air duct temperature of the air duct, so as to ensure that the system uses the optimal speed, ensure the reliability and stability of the system, and improve the user experience at the same time, solving the problem that the overall air supply air volume of the product is lower than expected, affecting the user experience of the product.

[0121] In order to implement the above embodiments, the present disclosure also proposes a control device for air supply equipment.

[0122] Figure 3This is a structural block diagram of a control device for an air supply device provided in the third embodiment of the present disclosure.

[0140] A calculation module, used to calculate the actual air volume of the air supply device according to the air outlet wind speed and the cross-sectional area of ​​the air duct;

[0141] A third determination module is used to obtain a reference air volume corresponding to the current working condition according to the factory parameters of the air duct;

[0142] The second correction module is used to correct the rotation speed of the fan based on the relationship between the actual air volume and the reference air volume.

[0143] Optionally, the second correction module is specifically used to:

[0146] If the actual air volume is less than the reference air volume, increasing the current speed of the fan based on the speed correction amount;

[0147] If the actual air volume is greater than the reference air volume, the current speed of the fan is reduced based on the speed correction amount.

[0148] In the disclosed embodiment, the air inlet temperature and the air outlet temperature of the air duct under the current working condition are first obtained, and then the first temperature difference between the air inlet temperature and the air 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 magnitude relationship between the first temperature difference and the second temperature difference, the working parameters of the compressor in the air supply device are corrected. Thus, the second temperature difference when the air supply device is in the optimal air supply state is determined by the factory parameters of the air duct and the current working condition, and then the working parameters of the compressor are corrected by comparing the magnitude relationship between the first temperature difference and the second temperature difference. By changing the working state of the compressor and thus affecting the fan speed, the fan can be at the optimal speed, ensuring stable and reliable operation of the system, avoiding problems such as overload of the indoor unit during heating, frequency reduction for anti-freezing of refrigeration, shutdown or water blowing caused by reduced air volume, and improving the user experience.
