Description

Technical Field

[0001] This invention relates to an adaptive control system and method for noise in an air conditioner indoor unit, belonging to the field of air conditioning technology. Background Technology

[0002] With the development of air conditioning technology, air conditioners have become increasingly popular due to their energy-saving performance, intelligent control, and high comfort. Electronic expansion valves, in particular, are widely used in the indoor and outdoor units of inverter air conditioning units due to their wide control range and high precision. Controlling the electronic expansion valve is a crucial part of air conditioning technology; the proper control of the valve directly affects the unit's performance and the user experience.

[0003] During operation, the electronic expansion valve (EXV) of the indoor unit of an air conditioning system remains at a certain opening. Changes in system status, installation conditions, or inconsistencies in the electronic expansion valve's performance can all cause noise in the indoor unit. Chinese patent application number 201510009479.X discloses a control method and device for the electronic expansion valve of an indoor unit, addressing the problem of condensation and noise caused by the electronic expansion valve not fully closing when the unit is off. This method adjusts the opening of the electronic expansion valve by detecting the pipe temperature of the off indoor unit. However, this control method does not address the actual noise generated; it assumes the possibility of noise. When users are dissatisfied with the sound quality generated by refrigerant passing through the electronic expansion valve (EXV), timely control and adjustment are impossible. Furthermore, when repair personnel visit the unit, it is difficult to detect the same noise as previously reported by the user, making the repair process challenging. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an adaptive control system and method for air conditioner indoor unit noise, thereby solving the problem that air conditioner indoor unit noise cannot be adaptively improved.

[0005] To achieve the above objectives, the present invention is implemented using the following technical solution:

[0006] In a first aspect, the present invention provides an adaptive noise control method for an air conditioner indoor unit, comprising the following steps:

[0007] Obtain user noise feedback information to determine the current operating status of the indoor unit of the air conditioner;

[0008] Based on the current operating status of the indoor unit of the air conditioner, an adaptive adjustment command is sent to the electronic expansion valve to control the opening degree of the electronic expansion valve;

[0009] After controlling the opening of the electronic expansion valve, the system receives feedback from the user's operation information and determines whether to continue adjusting the opening of the electronic expansion valve or stop adjusting it based on the feedback, resulting in a better improvement effect.

[0010] In conjunction with the first aspect, the user operation information further includes: improvement effective, improvement ineffective, continued improvement, and improvement satisfaction.

[0011] Furthermore, when the feedback from the received user operation information is satisfactory, or when the user does not provide feedback on operation information, the adaptive control ends and stops adjusting the opening of the electronic expansion valve;

[0012] If the feedback from the received user operation information indicates that the improvement is effective and further improvement is needed, continue to adjust the opening of the electronic expansion valve as before.

[0013] Furthermore, when the feedback from the received user operation information indicates a failure to improve the system, the electronic expansion valve is controlled to adjust its opening in the opposite direction.

[0014] Furthermore, the air conditioner indoor unit controller receives user operation information to improve the failure and controls the adjustment of the electronic expansion valve opening to be opposite to the electronic expansion valve opening when the failure is improved.

[0015] Furthermore, the operating states include: heating standby state, heating stop state, heating operation state, cooling operation state, and cooling stop or cooling standby state.

[0016] Furthermore, when the current operating state of the indoor unit of the air conditioner is any of the following states: heating standby state, heating stop state, or cooling operation state, the indoor unit controller of the air conditioner controls the electronic expansion valve to reduce the set value opening based on the existing opening degree.

[0017] When the current operating state of the indoor unit of the air conditioner is heating operation, the controller of the indoor unit of the air conditioner controls the electronic expansion valve to increase the set value opening based on the existing opening;

[0018] The opening values ​​set above can be the same or different values.

[0019] When the current operating state of the indoor unit of the air conditioner is cooling off or cooling standby, the opening degree of the electronic expansion valve is reset to 0PLS.

[0020] Secondly, the present invention provides an adaptive control system for the noise of an air conditioner indoor unit, the system comprising:

[0021] An electronic expansion valve is used to connect to the indoor unit controller of an air conditioner and execute adjustment commands issued by the indoor unit controller.

[0022] The air conditioner indoor unit controller is used to receive user noise feedback information, determine the current operating status of the air conditioner indoor unit, and control and adjust the opening of the electronic expansion valve in real time based on the feedback of user operation information.

[0023] A computer system includes a processor and a storage medium; the storage medium is used to store adjustment instructions.

[0024] The processor is configured to operate according to the instructions to perform the steps of the method according to any of the preceding claims.

[0025] A computer-readable storage medium having a computer program stored thereon that, when executed by a processor, implements the steps of the method described in any of the preceding claims.

[0026] Compared with the prior art, the beneficial effects achieved by the present invention include:

[0027] This invention provides an adaptive control system for indoor unit noise of an air conditioner, which performs real-time processing based on user noise feedback to adaptively improve the noise of the indoor unit of the air conditioner;

[0033] Figure 5 This is a flowchart of the air conditioner indoor unit noise adaptive adjustment method in cooling stop or cooling standby state provided in an embodiment of the present invention. Detailed Implementation

[0034] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0035] This invention provides an adaptive control system and method for air conditioner indoor unit noise. Based on the basic control principle of the electronic expansion valve of the air conditioner indoor unit, and considering different operating states of the indoor unit, an adaptive noise control method for the indoor unit is proposed. When a user perceives noise from the air conditioner, the user performs a "noise feedback," "effective improvement," "ineffective improvement," "continue improvement," or "satisfactory improvement" operation. The indoor unit controller, by judging the current operating state of the indoor unit and the user's feedback, adaptively adjusts the opening degree of the electronic expansion valve (EXV) until the optimal opening degree is found.

[0036] When the indoor unit of the air conditioner is running, the electronic expansion valve of the indoor unit operates based on the following opening rule:

[0037] Heating: 0PLS < X1 (opening degree of electronic expansion valve with flow of 0) < X2 (opening degree of indoor unit EXV when heating is stopped) ≤ X3 (opening degree of indoor unit EXV when heating is in standby) < X4 (minimum opening degree of indoor unit EXV when heating is running) ≤ X5 (opening degree of indoor unit EXV when heating is running) ≤ X6 (maximum opening degree of indoor unit EXV when heating is running);

[0038] Cooling: When cooling is off, the opening degree of the indoor unit EXV is equal to the opening degree of the indoor unit EXV when cooling is on standby. 0PLS < Y1 (the opening degree of the electronic expansion valve when the flow rate is 0) < Y2 (the minimum opening degree of the indoor unit EXV when cooling is running) ≤ Y3 (the opening degree of the indoor unit EXV when cooling is running) ≤ Y4 (the maximum opening degree of the indoor unit EXV when cooling is running).

[0039] In practice, when a user provides "noise feedback," the air conditioner detects the current state of the indoor unit and classifies it into "heating standby" (i.e., "heating to temperature point standby state"), heating stop state, heating operation state, cooling operation state, cooling stop state, or cooling standby state. In the following embodiments, parentheses () indicate no boundary, and square brackets [] indicate a boundary, such as (T, J] indicating T < ≤ J.

[0040] Example 1

[0041] like Figure 1 The diagram shown is a flowchart of the air conditioner indoor unit noise adaptive adjustment method in heating standby state provided in this embodiment. Heating standby means that the indoor unit is set to heating state, but the indoor temperature has reached the set temperature, that is, the indoor unit is in the state of heating to the temperature point. When designing the air conditioner indoor unit, the indoor unit in heating standby state will usually have a fixed opening degree.

[0042] The electronic expansion valve of the air conditioner indoor unit has an opening of 0 for flow rate. When the current opening of the electronic expansion valve of the air conditioner indoor unit is less than this opening, no refrigerant passes through this electronic expansion valve; when it is greater than this opening, refrigerant passes through this electronic expansion valve.

[0043] After the user provides "noise feedback," when the controller detects that the indoor unit of the air conditioner is currently in heating standby mode, the adaptive adjustment process in this embodiment is as follows:

[0044] Reduce the opening of the electronic expansion valve of the indoor unit of the air conditioner by A from the current fixed opening value. After adjusting the opening of the electronic expansion valve, the noise level of the indoor unit will change accordingly. If the user's operation is effective, it means that the direction of reducing the electronic expansion valve is correct. The user can further optimize the noise of the indoor unit of the air conditioner by clicking "Continue to Improve" in the same direction of electronic expansion valve operation. If the user is satisfied with the improved noise, they can click "Satisfied with Improvement". Alternatively, if the user does not perform any operation for a long time, it is assumed that the user is satisfied with the improved noise. At this time, the improvement ends and the improvement result is recorded.

[0045] When the user reports "improvement failure" after the first operation of the indoor unit's electronic expansion valve and the A opening degree is reduced, it means that the user is not satisfied with the improved noise level and the direction of the indoor unit's electronic expansion valve's reduction is incorrect. In this case, the indoor unit's electronic expansion valve should be operated in the opposite direction; the opening degree of the air conditioner's indoor unit's electronic expansion valve should be increased by the A opening degree based on the current opening degree value.

[0046] In this way, through the user's improved operation, the opening of the electronic expansion is adjusted in the correct direction to reduce noise, and the final improvement result is recorded.

[0047] in:

[0048] The value of A is greater than 0 and less than X3 (the opening degree of the indoor unit EXV when in heating standby mode);

[0049] When the electronic expansion valve is adjusted to a smaller size, the opening degree of the electronic expansion valve after adjustment should be greater than X1 (the opening degree when the flow rate of the electronic expansion valve is 0).

[0050] When adjusting the electronic expansion valve, ensure that the opening of the electronic expansion valve after adjustment is less than X4 (the minimum opening of the indoor unit EXV during heating operation).

[0051] pass Figure 1 "Adaptive Noise Adjustment for Indoor Unit in Heating Standby" enables the opening of the indoor unit's electronic expansion valve EXV to adaptively adjust between (X1, X4) and fix at a noise-free opening.

[0052] Example 2

[0053] Figure 2 This is a flowchart of the air conditioner indoor unit noise adaptive adjustment method for heating shutdown state provided in this embodiment.

[0054] When designing an indoor air conditioner, the indoor unit is usually fixed at a certain opening when it is in heating off state. The electronic expansion valve of the indoor air conditioner has an opening of 0 for flow. When the current opening of the electronic expansion valve of the indoor air conditioner is less than this opening, no refrigerant passes through this electronic expansion valve. When it is greater than this opening, refrigerant passes through this electronic expansion valve.

[0055] After the user provides "noise feedback," when the controller detects that the indoor unit of the air conditioner is currently in heating off state, the adaptive adjustment process in this embodiment is as follows:

[0056] Reduce the opening of the electronic expansion valve of the indoor unit of the air conditioner by B from the current fixed opening value. After adjusting the current opening of the electronic expansion valve, the noise level of the indoor unit will change accordingly. If the user's operation is effective, it means that the direction of reducing the electronic expansion valve is correct. The user can further optimize the noise of the indoor unit of the air conditioner by clicking "Continue to Improve" in the same direction of electronic expansion valve operation. If the user is satisfied with the improved noise, they can click "Satisfied with Improvement". Alternatively, if the user does not perform any operation for a long time, it is assumed that the user is satisfied with the improved noise. At this time, the improvement ends and the improvement result is recorded.

[0057] When the user reports "improvement failed" after the first operation of the indoor unit's electronic expansion valve and the B opening is reduced, it means that the user is not satisfied with the improved noise and the direction of the indoor unit's electronic expansion valve's reduction is incorrect. In this case, the indoor unit's electronic expansion valve should be operated in the opposite direction; the B opening of the air conditioner's indoor unit's electronic expansion valve should be increased from the current opening value.

[0058] In this way, through the user's improved operation, the opening of the electronic expansion is adjusted in the correct direction to reduce noise, and the final improvement result is recorded.

[0059] in:

[0060] The value of B is greater than 0 and less than the current opening degree;

[0061] When the electronic expansion valve is adjusted to a smaller size, the opening degree of the electronic expansion valve after adjustment should be greater than X1 (the opening degree when the flow rate of the electronic expansion valve is 0).

[0062] When adjusting the electronic expansion valve, ensure that the opening of the electronic expansion valve after adjustment is less than X4 (the minimum opening of the indoor unit EXV during heating operation).

[0063] pass Figure 2 "Adaptive Noise Adjustment for Indoor Unit During Heating Shutdown" enables the opening of the indoor unit's electronic expansion valve EXV to adaptively adjust between (X1, X4) and then fix it at a noise-free opening.

[0064] Example 3

[0065] Figure 3The flowchart of the air conditioner indoor unit noise adaptive adjustment method in heating operation state provided in this embodiment is as follows: After the user provides "noise feedback", when the controller detects that the air conditioner indoor unit is currently in heating operation state, it records the current opening degree of the indoor unit's electronic expansion valve and marks it as M PLS. The adaptive adjustment process in this embodiment is as follows:

[0066] Increase the opening of the electronic expansion valve of the indoor unit of the air conditioner to the "M+C" opening, and at the same time block the opening between [M, M+C). After adjusting the current electronic expansion valve opening, the noise value of the indoor unit will change accordingly. If the user's operation is effective, it means that the direction of the electronic expansion valve adjustment is correct. The user can further optimize the noise of the indoor unit of the air conditioner by "Continue to Improve" in the same direction of the electronic expansion valve operation. If the user is satisfied with the improved noise, he / she can operate "Improvement Satisfied". If the user has not performed any operation for a long time, it is assumed that the user is satisfied with the improved noise. At this time, the improvement ends and the improvement result is recorded. The electronic expansion valve opening range between [M, M+C) is blocked.

[0067] When the indoor unit electronic expansion valve is operated for the first time and the [M,M+C] range is blocked, if the user reports "improvement failure", it means that the user is not satisfied with the improved noise and the direction of the indoor unit electronic expansion valve's adjustment is incorrect. In this case, the indoor unit electronic expansion valve should be operated in the opposite direction. Record the current opening degree of the indoor unit electronic expansion valve, mark it as N PLS, and reduce the opening degree of the air conditioner indoor unit electronic expansion valve to "NC" while blocking the opening degree range of (NC,N).

[0068] In this way, through the user's improved operation, the opening of the electronic expansion is adjusted in the correct direction to reduce noise, and the final improvement result is recorded.

[0069] in:

[0070] The value of M is the current operating opening value of the indoor unit, which is greater than 0 and less than the maximum operating opening value of the indoor unit;

[0071] The value of C is greater than 0 and less than the value of "maximum operating degree of indoor unit - current operating degree of indoor unit M";

[0072] The value of N is the adjusted current operating opening value of the indoor unit, which is greater than 0 and less than the maximum operating opening value of the indoor unit;

[0073] When representing an open interval, parentheses indicate that the endpoints are not included, and square brackets indicate that the endpoints are included.

[0074] When adjusting the noise during heating operation, based on air conditioning design experience, the electronic expansion valve of the indoor unit will operate in the direction of increasing the noise level the first time.

[0075] pass Figure 3"Adaptive Noise Adjustment for Indoor Unit During Heating Operation" enables the opening of the indoor unit's electronic expansion valve EXV to be adaptively adjusted between [X4, X6], and shields some noisy openings.

[0076] Example 4

[0077] Figure 4 The flowchart of the air conditioner indoor unit noise adaptive adjustment method in cooling operation state provided in this embodiment is as follows: First, after the user provides "noise feedback", when the controller detects that the current air conditioner indoor unit is in cooling operation state, it records the current opening degree of the indoor unit's electronic expansion valve and marks it as P PLS;

[0078] Reduce the opening of the electronic expansion valve of the indoor unit to "PD" and simultaneously block the opening between (PD, P). After adjusting the current opening of the electronic expansion valve, the noise level of the indoor unit will change accordingly. If the user's operation is effective, it means that the direction of the electronic expansion valve's closing action is correct. The user can further optimize the noise of the indoor unit by clicking "Continue to Improve" in the same direction of the electronic expansion valve's action. If the user is satisfied with the improved noise, they can click "Satisfied with Improvement". Alternatively, if the user has not performed any operation for a long time, it is assumed that the user is satisfied with the improved noise. At this point, the improvement ends, and the improvement result is recorded. The electronic expansion valve opening range between (PD, P) is blocked.

[0079] When the indoor unit electronic expansion valve is operated for the first time and the (PD, P) interval is blocked, if the user reports "improvement failure", it means that the user is not satisfied with the improved noise and the direction of the indoor unit electronic expansion valve's closing action is incorrect. In this case, the indoor unit electronic expansion valve should be operated in the opposite direction. Record the current opening degree of the indoor unit electronic expansion valve, mark it as Q PLS, and increase the opening degree of the air conditioner indoor unit electronic expansion valve to the "Q+D" opening degree, while blocking the opening degree interval between [Q, Q+D).

[0080] In this way, through the user's improved operation, the opening of the electronic expansion is adjusted in the correct direction to reduce noise, and the final improvement result is recorded.

[0081] Where: P is the current operating opening value of the indoor unit, which is greater than 0 and less than the maximum operating opening value of the indoor unit; PLS is the opening unit of the electronic expansion valve; D is greater than 0 and less than the value of "current operating opening P of the indoor unit"; (PD,P] represents the interval greater than PD and less than or equal to P, parentheses indicate that the endpoints are not included, and square brackets indicate that the endpoints are included;

[0082] When adjusting the noise during cooling operation, based on air conditioning design experience, the electronic expansion valve of the indoor unit will operate in the direction of decreasing noise the first time.

[0083] pass Figure 4"Adaptive Noise Adjustment for Indoor Unit During Cooling Operation" enables the opening of the indoor unit's electronic expansion valve EXV to adaptively adjust between [Y2, Y4], and shields some noisy openings.

[0084] Example 5

[0085] Figure 5 The flowchart of the noise adaptive adjustment method for the indoor unit of an air conditioner in cooling stop or cooling standby states provided in this embodiment is as follows: When designing the indoor unit of an air conditioner, the indoor unit in the cooling standby state and cooling stop state will close the opening of the electronic expansion valve to 0PLS.

[0086] After the user provides "noise feedback", the controller detects whether the indoor unit of the air conditioner is in cooling standby mode or cooling off mode; this indicates that the electronic expansion of the indoor unit may not actually be shut down to 0PLS at this time.

[0087] Perform a reset action on the electronic expansion valve of the indoor unit of the air conditioner, and close the electronic expansion valve of the indoor unit back to 0PLS. After adjusting the current opening of the electronic expansion valve, the noise value of the indoor unit will change accordingly. If the user's operation is effective, it means that the reset action of the electronic expansion valve of the indoor unit is effective. If the user is satisfied with the improved noise, he / she can operate "Satisfied with the improvement". Alternatively, if the user does not perform any operation for a long time, it is assumed that the user is satisfied with the improved noise. At this time, the improvement ends and the improvement result is recorded.

[0088] When the user reports "improvement failed" after the electronic expansion valve of the indoor unit of the air conditioner has been reset, it means that the user is not satisfied with the improved noise. However, at this time, the electronic expansion valve of the indoor unit has been completely closed to 0PLS. At this time, the noise of the indoor unit may be due to leakage or jamming of the electronic expansion valve itself. There is no room for improvement in control, so the improvement ends.
