Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and in particular to a processing method, apparatus, air conditioning equipment and storage medium. Background Technology

[0002] With the rapid development of science and technology, air conditioning equipment has become increasingly sophisticated and its applications have become more widespread.

[0003] In related technologies, a pressure switch controller is installed on the variable frequency air conditioner to protect the pressure of the air conditioning system. When the pressure of the air conditioning system reaches the opening value of the pressure switch, the pressure switch will open and the air conditioner will stop running.

[0004] Therefore, when the air conditioner stops operating after the pressure reaches the pressure switch's cut-off value, it will affect the operating efficiency and usage efficiency of the air conditioning equipment, as well as the user experience.

[0005] Application content

[0006] To address the aforementioned technical problems, this application provides a processing method, apparatus, air conditioning equipment, and storage medium. The solution provided in this application can improve the operating efficiency and usage efficiency of the air conditioning equipment, as well as the user experience of the air conditioning equipment.

[0007] The solution in this application is implemented as follows:

[0008] In a first aspect, this application provides a processing method applied to an air conditioning device, the method comprising:

[0009] It is determined that the pressure of the air conditioning equipment is greater than the pressure threshold;

[0010] When the pressure is greater than the pressure threshold, the first frequency at which the compressor of the air conditioning equipment operates is obtained;

[0011] If the first frequency meets the first condition, control the air conditioning equipment to stop;

[0012] If the first frequency does not meet the first condition, the operating frequency of the compressor is reduced to a second frequency, and the state of the air conditioning equipment is controlled based on the second frequency; the state includes shutdown or operation.

[0013] Secondly, this application provides a processing apparatus deployed in an air conditioning unit, the processing apparatus comprising:

[0014] A determining unit is used to determine that the pressure of the air conditioning equipment is greater than a pressure threshold.

[0015] The obtaining unit is configured to obtain a first frequency at which the compressor of the air conditioning equipment operates in the current state when the pressure is greater than the pressure threshold.

[0016] A first control unit is configured to control the air conditioning equipment to shut down when the first frequency meets a first condition.

[0017] The second control unit is configured to reduce the operating frequency of the compressor to a second frequency when the first frequency does not meet the first condition, and control the state of the air conditioning equipment based on the second frequency; the state includes shutdown or operation.

[0018] Thirdly, this application provides an air conditioning device, the air conditioning device including a controller, the controller being used to execute the processing method described in the first aspect above.

[0019] Fourthly, this application provides a storage medium storing a control program, which, when executed, implements the processing method described in the first aspect.

[0020] The processing method, apparatus, air conditioning equipment, and storage medium provided in this application are applied to an air conditioning equipment, including: determining that the pressure of the air conditioning equipment is greater than a pressure threshold; when the pressure is greater than the pressure threshold, obtaining a first frequency at which the compressor of the air conditioning equipment operates; when the first frequency meets a first condition, controlling the air conditioning equipment to stop; when the first frequency does not meet the first condition, reducing the operating frequency of the compressor to a second frequency, and controlling the state of the air conditioning equipment based on the second frequency; the state includes stopping or running.

[0021] As can be seen, the proposed solution does not directly shut down the air conditioning unit when the pressure exceeds the pressure threshold. Instead, it analyzes the situation and shuts down only when the first condition is met. If the first condition is not met, the frequency is reduced, and the state of the air conditioning unit is controlled based on the reduced frequency. Therefore, when the pressure exceeds the pressure threshold, the air conditioning unit may shut down or continue operating. This achieves two goals: first, by shutting down the air conditioning unit when the first condition is met, the pressure components within the unit are protected from damage; second, by reducing the frequency when the first condition is not met, the operation of the air conditioning unit is controlled as much as possible, thus improving operating efficiency.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of the application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0028] In the following description, references are made to “some embodiments,” which describe a subset of all possible embodiments. However, it is understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0029] In the following description, the terms "first," "second," and "third" are used only to distinguish different objects and do not represent a specific order of objects, nor are they constituting a chronological order. It is understood that "first," "second," and "third" may be interchanged in a specific order or sequence where permitted, so that the embodiments of this application described herein can be implemented in an order other than that illustrated or described herein.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0031] The following describes various embodiments of the processing method and apparatus, air conditioning equipment, and storage medium provided in the embodiments of this application.

[0032] Firstly, embodiments of this application provide a processing method applied to a processing device; wherein the processing device can be deployed in an air conditioning unit. The processing procedure provided by embodiments of this application will be described below.

[0033] Figure 1 A flowchart illustrating one possible processing method is provided. (See reference) Figure 1 The processing method shown may include, but is not limited to, the following: Figure 1S101 to S104 are shown.

[0034] S101. The air conditioning equipment determines that the pressure of the air conditioning equipment is greater than the pressure threshold.

[0035] A pressure threshold is a standard for determining whether the system pressure of an air conditioning unit is within the normal range. This application does not limit the specific value of the pressure threshold; it can be determined based on actual circumstances.

[0036] S101 can be implemented as follows: the air conditioning equipment detects the system pressure of the air conditioning equipment through a pressure detector, and determines the relationship between the pressure and the pressure threshold. If the pressure is greater than the pressure threshold, it is determined that the pressure of the air conditioning equipment is greater than the pressure threshold.

[0037] The embodiments of this application do not limit the specific type of pressure detector, which can be determined according to the actual situation.

[0038] Optionally, the pressure switch can be disconnected if the pressure exceeds the pressure threshold.

[0039] S102. When the pressure is greater than the pressure threshold, the air conditioning equipment obtains the first frequency at which the compressor of the air conditioning equipment operates.

[0040] The first frequency is the initial operating frequency of the compressor when the pressure is greater than the pressure threshold.

[0041] For example, S102 can be implemented as follows: when the pressure is greater than the pressure threshold, the air conditioning device detects the operating frequency of the compressor of the air conditioning device through a frequency detector and uses the frequency as the first frequency.

[0042] The detection of the first frequency can be either direct measurement or calculation after measurement. This application does not specifically limit the method of obtaining the first frequency. For example, the first frequency can be measured using a frequency meter.

[0043] S103. When the first frequency meets the first condition, the air conditioning equipment is controlled to stop.

[0044] The first condition characterizes the frequency at which the air conditioning equipment needs to be shut down. This application does not limit the specific content of the first condition; it can be configured according to actual circumstances.

[0045] After obtaining the first frequency, the air conditioning equipment determines whether the first frequency meets the first condition. If the first condition is met, the air conditioning equipment is controlled to stop.

[0046] This application does not limit the specific implementation method for controlling the shutdown of air conditioning equipment, and can be determined according to the actual situation. For example, the air conditioning equipment sends a shutdown control signal through the controller, and controls the power supply of the air conditioning equipment through the shutdown control signal, thereby shutting down the equipment.

[0047] S104. If the first frequency does not meet the first condition, the air conditioning equipment reduces the operating frequency of the compressor to a second frequency, and controls the state of the air conditioning equipment based on the second frequency.

[0048] The states include shutdown or operation.

[0049] The second frequency is the frequency after the compressor has been reduced in frequency.

[0050] Since the failure to meet the first condition indicates that the air conditioning equipment may not need to be shut down, S104 can be implemented as follows: the air conditioning equipment determines that the first frequency does not meet the first condition, reduces the frequency at which the compressor operates, operates the compressor at the second frequency, and then controls the state of the air conditioning equipment based on the second frequency.

[0051] The embodiments of this application do not limit the method of reducing the operating frequency of the compressor, and can be configured according to the actual situation.

[0052] In one possible implementation, the frequency reduction can be based on a fixed value, meaning the frequency value of each reduction is fixed. For example, the first frequency is 100, and then it is successively reduced to 95, 90, and so on.

[0053] In another possible implementation, the frequency can be proportionally reduced based on the previous frequency value. For example, the first frequency is 100, and then it is reduced to 90, 81, and so on.

[0054] Understandably, there are other ways to reduce the frequency, which will not be listed here.

[0055] There are no restrictions on the method of controlling the state of the air conditioning equipment based on the second frequency; it can be determined according to the actual situation. For example, the method of controlling the state of the air conditioning equipment based on the second frequency can be the same as the control method corresponding to the first frequency, or it can be different from the control method corresponding to the first frequency.

[0056] In this way, reducing the frequency may lower the system pressure of the air conditioning equipment, thereby reaching the operating state, thus increasing the probability of operation and improving the operating efficiency and utilization efficiency of the air conditioning equipment.

[0057] The processing method provided in this application embodiment is applied to an air conditioning device. The processing method includes: determining that the pressure of the air conditioning device is greater than a pressure threshold; when the pressure is greater than the pressure threshold, obtaining a first frequency at which the compressor of the air conditioning device operates; when the first frequency meets a first condition, controlling the air conditioning device to stop; when the first frequency does not meet the first condition, reducing the operating frequency of the compressor to a second frequency, and controlling the state of the air conditioning device based on the second frequency; the state includes stopping or running.

[0058] As can be seen, the proposed solution does not directly shut down the air conditioning unit when the pressure exceeds the pressure threshold. Instead, it analyzes the situation and shuts down only when the first condition is met. If the first condition is not met, the frequency is reduced, and the state of the air conditioning unit is controlled based on the reduced frequency. Therefore, when the pressure exceeds the pressure threshold, the air conditioning unit may shut down or continue operating. This achieves two goals: first, by shutting down the air conditioning unit when the first condition is met, the pressure components within the unit are protected from damage; second, by reducing the frequency when the first condition is not met, the operation of the air conditioning unit is controlled as much as possible, thus improving operating efficiency.

[0059] The process of controlling the state of the air conditioning equipment based on the second frequency in S104 will be described below.

[0060] like Figure 2 As shown, the process may include, but is not limited to, S1041 and S1042 described below.

[0061] S1041. When the second frequency meets the first condition, the air conditioning equipment is controlled to stop.

[0062] S1041 can be implemented as follows: the air conditioning equipment determines whether the second frequency meets the first condition, and if the second frequency meets the first condition, controls the air conditioning equipment to stop. The process of determining whether the second frequency meets the first condition and controlling the air conditioning equipment to stop can be found in the detailed description of S103, where the air conditioning equipment is controlled to stop when the first frequency meets the first condition; it will not be repeated here.

[0063] S1042. When the second frequency does not meet the first condition, the air conditioning equipment obtains the current difference of the air conditioning equipment and controls the state of the air conditioning equipment based on the current difference.

[0064] Current difference is used to measure the decrease in current when the frequency is reduced. The current difference can be used to determine whether the pressure of the air conditioning equipment has returned to normal after the frequency is reduced, so that the air conditioning equipment can continue to operate.

[0065] The current difference is the difference between the reference current of the air conditioning device and the first current of the air conditioning device.

[0066] The reference current is the current of the air conditioning device when it operates at the first frequency, and the first current is the current of the air conditioning device when it operates at the second frequency.

[0067] S1042 can be implemented as follows: when the air conditioning equipment determines that the second frequency does not meet the first condition, it obtains the current of the air conditioning equipment when it is running at the first frequency as a reference current, obtains the current of the air conditioning equipment when it is running at the second frequency as a first current, subtracts the first current from the reference current as the difference as the current difference, and controls the air conditioning equipment to stop or continue to run based on the current difference.

[0068] The specific method for controlling the air conditioning equipment to stop or continue operating based on the current difference is not limited and can be configured according to the actual situation.

[0069] The process of controlling the state of the air conditioning equipment based on the current difference in S1042 will be described below.

[0070] like Figure 3 As shown, in one possible implementation, the process may include, but is not limited to, S10421 and S10422.

[0071] S10421. When the current difference is greater than the first threshold, the air conditioning equipment is controlled to continue operating at the second frequency.

[0072] The first threshold is used to measure whether the current difference is sufficient to allow the air conditioning equipment to continue operating. This application does not limit the specific value of the first threshold; it can be determined according to actual circumstances.

[0073] For example, the first threshold can be an empirical value or a theoretical value calculated based on certain parameters.

[0074] S10421 can be implemented as follows: the air conditioning equipment determines the relationship between the current difference and the first threshold, and if the current difference is greater than the first threshold, controls the compressor of the air conditioning equipment to continue running at the second frequency.

[0075] S10422. When the current difference is less than or equal to the first threshold, the air conditioning equipment continues to reduce the operating frequency of the compressor to a third frequency, uses the third frequency as the new second frequency, and controls the state of the air conditioning equipment based on the new second frequency.

[0076] S10422 can be implemented as follows: when the current difference is less than or equal to the first threshold, the air conditioning device continues to reduce the operating frequency of the compressor to a third frequency, uses the third frequency as the new second frequency, determines whether the third frequency meets the first condition, and controls the air conditioning device to stop when the third frequency meets the first condition; when the third frequency does not meet the first condition, obtains the new current difference of the air conditioning device, and controls the state of the air conditioning device based on the new current difference.

[0077] For example, if the current difference is greater than the first threshold, the air conditioning equipment is controlled to continue operating at the third frequency; if the current difference is less than or equal to the first threshold, the frequency of the compressor operation is further reduced to the fourth frequency, the fourth frequency is used as the new second frequency, and the state of the air conditioning equipment is controlled based on the new second frequency.

[0078] Wherein, the new current difference is the difference between the reference current of the air conditioning equipment and the second current of the air conditioning equipment; the second current is the current of the air conditioning equipment when it is running at the third frequency.

[0079] The process of reducing the operating frequency of the compressor to the third frequency can be referred to in the detailed description of the air conditioning equipment reducing the operating frequency of the compressor to the second frequency in S104, and will not be repeated here.

[0080] The process of reducing the operating frequency of the compressor to a second frequency in S104 will be described below.

[0081] In one possible implementation, the air conditioning device may reduce the operating frequency of the compressor to the second frequency based on the first formula.

[0082] The first formula includes: F n+1 = n×M×F-(n-1)×F; where F n+1 The second frequency is represented by F; the first frequency is represented by M; the reduction coefficient is greater than 0 and less than 1; n is the number of reductions is greater than or equal to 0.

[0083] This application does not limit the specific value of the reduction coefficient, which can be determined according to the actual situation. M is greater than 0 and less than 1. For example, M is 0.95.

[0084] For example, if the first frequency is 100, the frequencies after downsampling based on the first formula are 95 and 90.

[0085] The first condition will now be explained in detail.

[0086] In one possible implementation, the first condition may include: the frequency is less than or equal to a first frequency threshold.

[0087] The specific value of the first frequency threshold is not limited in the embodiments of this application and can be determined according to the actual situation.

[0088] For example, the first frequency threshold can be the lower limit of the operating frequency of the compressor at the current ambient temperature.

[0089] Understandably, the first frequency threshold can also be an empirical value in practice.

[0090] In another possible implementation, the first condition may include: the frequency is greater than the first frequency threshold and the frequency is less than or equal to the second frequency threshold.

[0091] The second frequency threshold is greater than the first frequency threshold.

[0092] The embodiments of this application do not limit the specific value of the second frequency threshold, which can be determined according to the actual situation.

[0093] For example, when the first frequency threshold is the lower limit of the compressor's operating frequency at the current ambient temperature, the value of the second frequency threshold may include, but is not limited to, the following case one or case two.

[0094] Case 1: The second frequency threshold is the average of the upper limit of the compressor's operating frequency at the current ambient temperature and the lower limit of the compressor's operating frequency at the current ambient temperature.

[0095] Case 2: The second frequency threshold satisfies the second formula;

[0096] The second formula includes: The F Y The second frequency threshold is represented by Fmax, which represents the upper limit of the operating frequency of the compressor under the current ambient temperature; Fmin represents the lower limit of the operating frequency of the compressor under the current ambient temperature; and F represents the first frequency.

[0097] The following describes the processing procedure provided in the embodiments of this application, taking a variable frequency air conditioning unit as an example.

[0098] like Figure 4 As shown, the process may include, but is not limited to, S401 to S411 below.

[0099] S401. When the user starts the air conditioner and the pressure switch is turned off, the current compressor operating frequency F is detected, the minimum operating frequency Fmin and the maximum target frequency Fmax of the compressor in the current mode are detected, and the current current I is recorded.

[0100] S402. Determine whether F is greater than Fmin.

[0101] If F is less than or equal to Fmin, execute S403 as follows; if F is greater than Fmin, execute S404 as follows.

[0102] S403, the compressor has stopped running.

[0103] S404. Determine if F is less than or equal to F.

[0104] If F is less than or equal to Then execute S405 below; if F is greater than Then execute S406 as follows.

[0105] S405, the compressor has stopped running.

[0106] S406, the compressor frequency reduction is n×M×F-(n-1)×F.

[0107] S407. Determine whether n×M×F-(n-1)×F is less than or equal to 1 / 2.

[0108] If n×M×F-(n-1)×F is less than or equal to Then execute S408 below; if n×M×F-(n-1)×F is greater than Then execute S409 as described below.

[0109] S408, the compressor has stopped running.

[0110] S409. The compressor operates at the reduced frequency and the reduced current In is recorded.

[0111] n = 1, 2, 3...

[0112] S410. Determine whether I-In is greater than a.

[0113] a is greater than 0.

[0114] If I-In is greater than a, then execute S411 below; if I-In is less than or equal to a, then add 1 to n and return to execute S406.

[0115] S411, The compressor operates at the reduced frequency.

[0116] The process is described in detail below.

[0117] After the user starts the air conditioning system, when the pressure exceeds the pressure switch disconnection value, the current compressor operating frequency F is detected. The highest operating frequency of the compressor under the current load mode is recorded as Fmax and the lowest operating frequency Fmin. The current total current I of the air conditioning equipment is also recorded.

[0118] If the current operating frequency F is equal to the minimum operating frequency Fmin, the compressor will shut down for protection.

[0119] If the current operating frequency F is greater than the minimum operating frequency Fmin, then determine whether the current operating frequency F is greater than or equal to the minimum operating frequency Fmin. The size relationship between them, when F is less than or equal to When this happens, the compressor stops running to protect it.

[0120] If F is greater than The compressor frequency is reduced by 0.95F, and the reduced frequency is 0.95F. Determine if 0.95F is less than or equal to... When this happens, the compressor will stop running to protect it.

[0121] If 0.95F is greater than If the frequency is reduced, the current after frequency reduction is recorded as I1. The difference between I and I1 is determined. If T-I1>a, the compressor will continue to run at the frequency after frequency reduction.

[0122] If T-I1≤a, then the compressor continues to reduce its frequency. For example, if the frequency of the compressor after frequency reduction is 0.95×2F-F, then it is determined whether 0.95×2F-F is equal to a. The size between them, if 0.95 × 2F - F is less than or equal to The compressor will stop running if 0.95 × 2F - F is greater than 1. Then record the current I2 after frequency reduction, determine the difference between I and I2, and perform loop control in the same way.

[0123] The processing method of this application has the following technical effects:

[0124] It comprehensively considers the control of the compressor under various conditions (such as excessive compressor frequency, heat exchanger blockage, large indoor and outdoor loads) to prevent the pressure switch from disconnecting due to excessive pressure. It fully protects the compressor and ensures normal use for users, avoiding the risk of user complaints caused by the extreme practice of stopping the compressor all at once when the pressure is too high.

[0125] The processing method provided in the embodiments of this application will be described below through three examples.

[0126] Example 1: Excessive pressure caused by excessively high compressor frequency;

[0127] Example 2: Excessive pressure caused by heat exchanger blockage;

[0128] Example 3: Excessive pressure caused by excessive indoor and outdoor loads.

[0129] Example 1: For cases where the compressor frequency is too high, the processing procedure in this embodiment may include: the air conditioning equipment determines that the system pressure is greater than a pressure threshold, obtains the compressor's operating frequency (first frequency) F, F is greater than the minimum operating frequency Fmin, and determines whether F is higher than the minimum operating frequency Fmin. The relationship between their magnitudes, F is greater than The frequency was down-divided to 0.95F; the comparison between 0.95F and... The relationship between them is that 0.95F is greater than... Record the current after frequency reduction as I1, determine the difference between I and I1, T-I1>a, and the compressor will continue to run at the frequency of 0.95F after frequency reduction.

[0130] Example 2: For the case of heat exchanger blockage, the processing procedure in this embodiment may include: the air conditioning equipment determines that the system pressure is greater than a pressure threshold, obtains the compressor's operating frequency (first frequency) F, F is greater than the minimum operating frequency Fmin, and determines whether F is greater than the minimum operating frequency Fmin. The relationship between their magnitudes, F is greater than The frequency was down-divided to 0.95F; the comparison between 0.95F and... The relationship between them is that 0.95F is greater than... Record the current after frequency reduction as I1. Determine the difference between I and I1. If T - I1 ≤ a, the compressor continues to reduce its frequency. The frequency of the compressor after frequency reduction is 0.95 × 2F - F. Then, determine whether 0.95 × 2F - F is equal to a. The size, if 0.95 × 2F - F is less than or equal to The compressor will stop running if 0.95 × 2F - F is greater than 1. Then record the current I2 after frequency reduction, determine the difference between I and I2, and perform loop control in the same way.

[0131] Example 3: In the case of excessive indoor and outdoor loads, the processing procedure of this application embodiment may include: the air conditioning equipment determines that the system pressure is greater than the pressure threshold, obtains the compressor's operating frequency (first frequency) F, F = Fmin, and the compressor stops directly.

[0132] Alternatively, the processing procedure in this application embodiment may include: the air conditioning equipment determining that the system pressure is greater than a pressure threshold, obtaining a first frequency F of the compressor, where F is greater than the minimum operating frequency Fmin, and determining whether F is greater than or equal to the minimum operating frequency Fmin. The size relationship between them, F is less than or equal to The compressor has stopped running.

[0133] Secondly, to implement the above-mentioned processing method, an embodiment of this application provides a processing apparatus, which is deployed in an air conditioning device. The following is in conjunction with... Figure 5 The structural diagram of the processing device shown is used for explanation.

[0134] like Figure 5 As shown, the processing device 50 includes: a determining unit 501, an obtaining unit 502, a first control unit 503, and a second control unit 504.

[0135] Determining unit 501 is used to determine that the pressure of the air conditioning equipment is greater than a pressure threshold.

[0136] The obtaining unit 502 is used to obtain the first frequency at which the compressor of the air conditioning equipment operates in the current state when the pressure is greater than the pressure threshold.

[0139] In some embodiments, the second control unit 504 is further configured to:

[0140] If the second frequency meets the first condition, control the air conditioning equipment to stop;

[0141] If the second frequency does not meet the first condition, the current difference of the air conditioning device is obtained, and the state of the air conditioning device is controlled based on the current difference; the current difference is the difference between the reference current of the air conditioning device and the first current of the air conditioning device; the reference current is the current of the air conditioning device when it is running at the first frequency, and the first current is the current of the air conditioning device when it is running at the second frequency.

[0142] In some embodiments, the second control unit 504 is further configured to:

[0143] If the current difference is greater than the first threshold, the air conditioning equipment is controlled to continue operating at the second frequency;

[0144] If the current difference is less than or equal to the first threshold, the operating frequency of the compressor is further reduced to a third frequency, the third frequency is used as the new second frequency, and the state of the air conditioning equipment is controlled based on the new second frequency.

[0145] In some embodiments, the second control unit 504 is further configured to:

[0146] The compressor's operating frequency is reduced to the second frequency based on the first formula;

[0147] The first formula includes: F n+1 = n×M×F-(n-1)×F; where F n+1 The second frequency is represented by F; the first frequency is represented by M; the reduction coefficient is greater than 0 and less than 1; n is the number of reductions is greater than or equal to 0.

[0148] In some embodiments, the first condition includes: the frequency is less than or equal to a first frequency threshold;

[0149] or,

[0150] The first condition includes: the frequency is greater than the first frequency threshold and the frequency is less than or equal to the second frequency threshold; the second frequency threshold is greater than the first frequency threshold.

[0151] In some embodiments, the first frequency threshold includes:

[0152] The lower limit of the operating frequency of the compressor under the current ambient temperature.

[0153] In some embodiments, the second frequency threshold satisfies the second formula;

[0154] The second formula includes: The F Y The second frequency threshold is represented by Fmax, which represents the upper limit of the operating frequency of the compressor under the current ambient temperature; Fmin represents the lower limit of the operating frequency of the compressor under the current ambient temperature; and F represents the first frequency.
