Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular, to an air conditioner dehumidification method, device, electronic device, storage medium, and air conditioner. Background Art

[0002] At present, household air conditioners usually integrate a dehumidification mode, which is particularly important in the south, especially during the period of returning dampness and the plum rain season. Its main function is to remove excess moisture in the air rather than significantly reduce the ambient temperature. However, there is a gap between the performance of current air conditioners in the dehumidification mode and the expectations of users. Specifically, based on competitor tests and after-sales feedback, under the standard conditions of setting the indoor and outdoor temperatures at 27°C and the relative humidity at 80%, the performance of the air conditioner after running in the dehumidification mode for eight hours is poor, and the following situations occur:

[0003] (1) The room humidity can only be reduced from 80% to approximately 65%, indicating poor dehumidification efficiency.

[0004] (2) After reaching the preset temperature point, the air conditioner will stop running, and then the room humidity will quickly rebound and rise back to nearly 79%, with obvious humidity fluctuations.

[0005] (3) Frequent stop and restart lead to unstable humidity control, affecting user comfort and equipment stability.

[0006] The root causes of the above problems are as follows:

[0007] (1) In the dehumidification mode, the internal fan is generally locked at a low gear, often non-adjustable, and the operating frequency of the compressor is relatively low. Although the operating frequency of the compressor can be reduced, the lower the operating frequency of the compressor, the worse its operating reliability, and it is easy to have unstable operation of the compressor. At the same time, reducing the frequency will cause the evaporation temperature to decrease, further reducing the dehumidification demand required by users, which is very contradictory.

[0008] (2) When the air conditioner stops running due to reaching the preset temperature, since the internal fan continues to supply air and there is no corresponding temperature and humidity control mechanism, the humidity rises again.

[0009] (3) The control logic is too simple. Generally, the internal fan is locked at a low gear, and the operating frequency of the compressor is relatively low. Coupled with little cooling demand, it is easy to trigger the stop condition, resulting in humidity fluctuations.

[0010] Upon further analysis, it is found that due to the lower usage frequency of the dehumidification mode of the air conditioner compared to the conventional cooling mode, its functional design and algorithm optimization are usually relatively backward. In a dehumidification environment, the external environmental conditions are relatively mild, and the set temperature does not need to be too low, which easily causes the air conditioner to enter the shutdown state. Most current solutions are to reduce the operating frequency when the shutdown condition is reached, but this not only affects the stability and reliability of the compressor but also reduces the temperature of the evaporator, which in turn affects the dehumidification effect and forms a technical contradiction.

[0036] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0037] As Figures 1 to 4 shown, the present invention provides an air conditioner dehumidification method, including: when the air conditioner is turned on and the preset ambient temperature T set by the user 设内 and the instruction for the user to turn on the dehumidification mode are obtained; controlling the air conditioner to operate according to the normal dehumidification procedure, so that each heat exchange flow path of the indoor heat exchanger 1 including at least three parallel heat exchange flow paths in the indoor unit of the air conditioner is opened; obtaining the indoor ambient temperature T of the room where the air conditioner is located 内环 ; judging whether the indoor ambient temperature T 内环 continuously drops within a first preset time period; when the indoor ambient temperature T 内环 continuously drops within the first preset time period, judging the magnitude relationship between the difference between T 设内 and T 内环 and a first preset temperature difference ΔT1; when T 设内 -T 内环 <ΔT1, closing the first heat exchange flow path 11 among at least three heat exchange flow paths, so as to reduce the cooling capacity of the air conditioner and increase the air outlet temperature of the air conditioner.

[0038] In this way, the air conditioner dehumidification method of the present invention adjusts the magnitude of the cooling capacity output of the air conditioner by dynamically adjusting the number of heat exchange flow paths participating in heat exchange in the indoor heat exchanger 1 of the air conditioner, so as to achieve the effect of accurately controlling the indoor ambient temperature. Thus, while ensuring the dehumidification effect, it effectively avoids the indoor ambient temperature from being reduced too low during the dehumidification process, solves or optimizes the problem of the indoor ambient humidity rebounding and rising when the air conditioner stops, optimizes the dehumidification function of the air conditioner, solves the problem of poor dehumidification effect of the dehumidification mode of the air conditioner in the prior art, and improves the comfort experience of the user. In addition, the air conditioner dehumidification method of the present invention can also more precisely control the operating state of the air conditioner, reduce the energy consumption of the air conditioner, and extend the service life of the air conditioner.

[0039] Specifically, when the user turns on the air conditioner and selects the instruction to turn on the dehumidification mode, a preset ambient temperature T will also be set. 设内 After the air conditioner is turned on, when it obtains the preset ambient temperature T set by the user 设内 and the instruction to turn on the dehumidification mode obtained from the user, it will enter the dehumidification mode and operate according to the normal dehumidification procedure towards the preset ambient temperature T set by the user 设内 At this time, each heat exchange flow path of the indoor heat exchanger 1 including at least three parallel heat exchange flow paths in the indoor unit of the air conditioner is opened, so that each heat exchange flow path of the indoor heat exchanger 1 participates in heat exchange to quickly reduce the indoor environmental humidity. However, during the dehumidification process of the air conditioner, the indoor environmental temperature T 内环 may be lower than the preset ambient temperature T 设内 . By monitoring the change trend of the indoor environmental temperature T 内环 , once it is found that the indoor environmental temperature T 内环 continuously decreases within a preset time period, the difference between T 设内 and T 内环 will be compared with the magnitude relationship between the first preset temperature difference ΔT1. If the difference between T 设内 and T 内环 is less than the first preset temperature difference ΔT1, it indicates that the indoor environmental temperature T 内环 is close to or reaches the preset ambient temperature T 设内 , and there is a risk of excessive cooling. At this time, the cooling capacity of the air conditioner can be reduced by closing one heat exchange flow path of the indoor heat exchanger 1 (such as the first heat exchange flow path 11 among the three heat exchange flow paths), which not only increases the outlet air temperature of the air conditioner, thereby preventing the indoor environmental temperature from further decreasing to meet the actual temperature requirements of the user, but also avoids the phenomenon that when the indoor environmental temperature T 内环 reaches the preset ambient temperature T 设内 , the air conditioner stops running and the indoor environmental humidity rebounds rapidly, and also avoids the problem of unstable humidity control caused by frequent stop and restart of the air conditioner, optimizes the dehumidification efficiency of the air conditioner, avoids unnecessary energy waste caused by the air conditioner, and improves the comfort experience of the user.

[0040] Preferably, 0°C ≤ ΔT1 ≤ 1°C.

[0041] More preferably, ΔT1 = 0.5°C.

[0042] Specifically, the air conditioner dehumidification method of the present invention sets ΔT 1设定 to 0.5°C based on comprehensive consideration of user comfort and dehumidification effect. During the dehumidification process of the air conditioner, when the indoor environmental temperature T 内环 is close to and the preset ambient temperature T 设内When the first heat exchange flow path 11 of the indoor heat exchanger 1 is closed, it can effectively prevent the indoor environmental temperature T 内环 from dropping below the preset environmental temperature T 设内 , and at the same time, it can also maintain the dehumidification effect of the air conditioner.

[0043] As Figure 2 shown, the air conditioner dehumidification method includes: continuing to judge whether the indoor environmental temperature T 内环 continuously drops within the second preset time period; when the indoor environmental temperature T 内环 continues to drop within the second preset time period, judge the magnitude relationship between the difference between T 设内 and T 内环 and the second preset temperature difference ΔT2; when T 设内 -T 内环 <ΔT2, continue to close the second heat exchange flow path 12 among at least three heat exchange flow paths, so that the refrigerating capacity of the air conditioner continues to decrease and the air outlet temperature of the air conditioner continues to rise; wherein, ΔT2<ΔT1.

[0044] Specifically, the air conditioner dehumidification method of the present invention further refines the control strategy of the air conditioner by introducing the judgment of the second preset temperature difference ΔT2. When the indoor environmental temperature T 内环 continues to drop, and the difference between T 设内 and T 内环 is less than the second preset temperature difference ΔT2, one heat exchange flow path of the indoor heat exchanger 1 (such as the second heat exchange flow path 12 among the three heat exchange flow paths) will continue to be closed to further reduce the refrigerating capacity of the air conditioner and increase the air outlet temperature of the air conditioner, so as to prevent the indoor environmental temperature from further decreasing or when the indoor environmental temperature T 内环 reaches the preset environmental temperature T 设内 and then the air conditioner stops, resulting in a rapid rebound of the indoor environmental humidity. This helps to protect users from the over-cooled indoor environment in more extreme cases, and at the same time can maintain an appropriate indoor environmental humidity, ensuring the flexibility and efficiency of the dehumidification function of the air conditioner.

[0045] Preferably, -0.5°C ≤ ΔT2 ≤ 0.5°C.

[0046] More preferably, ΔT2 = 0°C.

[0047] Specifically, by setting ΔT2 to 0°C in the air conditioner dehumidification method of the present invention, it means that when the indoor environmental temperature T 内环 is slightly lower than the preset environmental temperature T 设内 , the air conditioner will take further protective measures, continue to close the second heat exchange flow path 12 of the indoor heat exchanger 1 to reduce the refrigerating capacity and increase the air outlet temperature, ensuring that the air conditioner can respond in time and prevent the indoor environmental temperature T 内环Further decrease while maintaining the dehumidification effect of the air conditioner, achieving efficient dehumidification of the air conditioner, which reflects the accuracy of the air conditioner in controlling the indoor environmental temperature and its high responsiveness to user needs.

[0048] As Figure 2 shown, the air conditioner dehumidification method includes: continuing to determine whether the indoor environmental temperature T 内环 continues to decrease within a third preset time period; when the indoor environmental temperature T 内环 continues to decrease within the third preset time period, determining the magnitude relationship between the difference between T 设内 and T 内环 and a third preset temperature difference ΔT3; when T 设内 - T 内环 < ΔT3, controlling the operating frequency of the compressor of the air conditioner to decrease or controlling the air conditioner to stop; wherein, ΔT3 < ΔT2.

[0049] Specifically, the air conditioner dehumidification method of the present invention introduces the judgment of the third preset temperature difference ΔT3 in order to avoid overcooling the indoor environment by controlling the operating frequency of the compressor to decrease or controlling the air conditioner to stop when the indoor environmental temperature T 内环 is much lower than the preset environmental temperature T 设内 , protecting users from the discomfort of low temperature, not only improving the energy efficiency ratio of the air conditioner, reducing unnecessary power consumption, but also extending the service life of the air conditioner, demonstrating the intelligent adjustment ability and energy-saving and environmental protection characteristics of the air conditioner in the dehumidification mode.

[0050] Preferably, -1°C ≤ ΔT3 ≤ 0°C.

[0051] More preferably, ΔT3 = -0.5°C.

[0052] Specifically, setting ΔT3 to -0.5°C in the air conditioner dehumidification method of the present invention means that when the indoor environmental temperature T 内环 is much lower than the preset environmental temperature T 设内 , the air conditioning system will take more aggressive protection measures, such as controlling the operating frequency of the compressor to decrease or controlling the air conditioner to stop, which takes into account the negative impact that too low temperature may have on user health and comfort. By adjusting the working state of the compressor in a timely manner, it effectively prevents the indoor environmental temperature T 内环 from dropping excessively, ensuring the overall performance of the air conditioner in the dehumidification mode and user satisfaction.

[0053] Optionally, the first preset time period, the second preset time period, and the third preset time period are all equal.

[0054] As Figure 2 shown, the air conditioner dehumidification method includes: when T 设内 - T内环 When it is ≥ ΔT1, control the air conditioner to continue running according to the normal dehumidification program.

[0055] When the indoor environmental temperature T 内环 and the preset environmental temperature T 设内 are greater than or equal to the first preset temperature difference ΔT1, the air conditioner will continue to run according to the normal dehumidification program. This means that within the allowable temperature difference range, the air conditioner will give priority to ensuring the dehumidification effect while taking into account temperature control, ensuring that in the initial stage of dehumidification or when the temperature difference is large, the air conditioner can quickly and effectively reduce the indoor environmental humidity to meet the user's dehumidification needs, reflecting the adaptability and flexibility of the air conditioner under different environmental conditions.

[0056] As Figure 2 shown, the air conditioner dehumidification method of the present invention specifically includes the following:

[0057] When the user turns on the air conditioner, selects the dehumidification mode, and sets the preset environmental temperature T 设内 , the air conditioner will run according to the normal dehumidification program, generally locking the air volume of the internal fan and often locking the operating frequency of the compressor. For example, the internal fan is at a low air volume, and the operating frequency of the compressor is around 40 Hz;

[0058] When the indoor environmental temperature T 内环 continuously drops within the first preset time period, and T 设内 -T 内环 <0.5 °C, close the first heat exchange flow path 11. At this time, the cooling capacity of the air conditioner decreases, which is equivalent to the indoor heat exchanger 1 becoming smaller, the tube temperature of the heat exchange tubes of the indoor heat exchanger 1 dropping, and the air outlet temperature of the air conditioner rising. This can reduce the cold output to ensure the temperature set by the user; if T 设内 -T 内环 ≥ ΔT1, the air conditioner continues to run according to the normal dehumidification program;

[0059] When the indoor environmental temperature T 内环 continues to drop within the second preset time period, and T 设内 -T 内环 <0 °C, it means that the cold output of the air conditioner is relatively large, resulting in the inability to balance the temperature set by the user. It is necessary to close the second heat exchange flow path 12. At this time, the cooling capacity of the air conditioner further decreases, which is equivalent to the indoor heat exchanger 1 becoming even smaller, the tube temperature of the heat exchange tubes of the indoor heat exchanger 1 further dropping, and the air outlet temperature of the air conditioner further rising. This further reduces the cold output of the air conditioner;

[0060] The air conditioner dehumidification method of the present invention mainly uses the indoor heat exchanger 1 with three heat exchange flow paths for illustration, ensuring that the final third heat exchange flow path 13 is always open; if the above steps cannot meet the balance of cold, the indoor environmental temperature T 内环Continue to decline continuously within the third preset time period, and T 设内 -T 内环 < -0.5°C, then control the operating frequency of the compressor of the air conditioner to decrease or even stop the air conditioner to stop the output of cooling capacity to ensure the indoor environmental temperature.

[0061] Each of the above preset temperature differences can be adjusted within a range of plus or minus 0.5°C based on experience and combined with temperature control. For example, ΔT1 can be adjusted to 0°C to 1°C, ΔT2 can be adjusted to -0.5°C to 0.5°C, and ΔT3 can be adjusted to -1°C to 0°C to expand the protection range while ensuring the control accuracy of the air conditioner.

[0062] Such as Figure 3 shown, when performing the step of closing the first heat exchange flow path 11 among at least three heat exchange flow paths, the air conditioner dehumidification method further includes: obtaining the actual pipe temperature T 实管 of the heat exchange pipes of the indoor heat exchanger 1 and the set pipe temperature threshold T 设管 ; judging whether T 实管 is greater than or equal to T 设管 ; when T 实管 <T 设管 , increase the wind speed Q of the internal fan of the indoor unit to ensure that T 实管 ≥T 设管 .

[0063] While closing the first heat exchange flow path 11 to adjust the cooling capacity, it is also possible to monitor the actual pipe temperature T 实管 of the heat exchange pipes of the indoor heat exchanger 1, and compare the actual pipe temperature T 实管 with the set pipe temperature threshold T 设管 . When the actual pipe temperature T 实管 is less than the set pipe temperature threshold T 设管 , increase the wind speed Q of the internal fan, which can effectively prevent the surface of the heat exchange pipes of the indoor heat exchanger 1 from condensing or freezing due to too low temperature, thereby affecting the dehumidification effect of the air conditioner and the normal operation of the air conditioner. It not only improves the stability and safety of the air conditioner, but also optimizes the energy distribution during the dehumidification process of the air conditioner, achieving the dual purposes of efficient dehumidification and temperature control of the air conditioner.

[0064] Such as Figure 4 shown, when performing the step of continuing to close the second heat exchange flow path 12 among at least three heat exchange flow paths, the air conditioner dehumidification method further includes: obtaining the actual pipe temperature T 实管 of the heat exchange pipes of the indoor heat exchanger 1 and the set pipe temperature threshold T 设管 ; judging whether T 实管 is greater than or equal to T 设管 ; when T 实管 <T 设管When it is, increase the air volume gear Q of the indoor fan of the indoor unit to ensure T 实管 ≥T 设管 .

[0065] As the air conditioner further closes the heat exchange flow path of the indoor heat exchanger 1, the importance of the second pipe temperature control of the heat exchange pipes of the indoor heat exchanger 1 becomes prominent. By continuously monitoring the actual pipe temperature T 实管 of the heat exchange pipes of the indoor heat exchanger 1, and comparing the actual pipe temperature T 实管 with the set pipe temperature threshold T 设管 , so as to increase the air volume gear Q of the indoor fan when the actual pipe temperature T 实管 is less than the set pipe temperature threshold T 设管 , which can effectively prevent the surface of the heat exchange pipes of the indoor heat exchanger 1 from condensing or freezing due to too low temperature, thus affecting the dehumidification effect of the air conditioner and the normal operation of the air conditioner. It not only improves the stability and safety of the air conditioner, but also optimizes the energy distribution during the dehumidification process of the air conditioner, achieving the dual purposes of high-efficiency dehumidification and temperature control of the air conditioner, reflecting the adaptive adjustment ability of the air conditioner in a complex environment.

[0066] Specifically, T 设管 = 4°C.

[0067] Specifically, the air conditioner dehumidification method of the present invention sets T 设管 to 4°C based on the lowest temperature requirement for the surface of the heat exchange pipes not to condense or freeze, and at the same time takes into account the safety and stability of the air conditioner operating in the dehumidification mode, ensuring that in any case, the surface temperature of the heat exchange pipes will not drop to a dangerous level that may cause condensation or freezing, thus avoiding the risk of reduced dehumidification efficiency and air conditioner damage, reflecting the scientificity and practicality of the air conditioner dehumidification method of the present invention.

[0068] As Figure 3 and Figure 4 shown, before performing the step of increasing the air volume gear Q of the indoor fan of the indoor unit, the air conditioner dehumidification method further includes: judging whether the air volume gear Q of the indoor fan is the highest air volume gear Q max ; when Q = Q max , controlling the operating frequency of the compressor of the air conditioner to decrease or controlling the air conditioner to stop; when Q ≠ Q max , performing the step of increasing the air volume gear Q of the indoor fan of the indoor unit of the air conditioner.

[0069] During the air conditioner dehumidification process, when the air volume gear Q of the indoor fan has reached the highest air volume gear Q max , but the actual pipe temperature T 实管 of the heat exchange pipes is still lower than the set pipe temperature threshold T 设管When this occurs, the air conditioner will take measures to reduce the operating frequency of the compressor or stop it to prevent the adverse effects caused by the excessively low actual tube temperature of the heat exchange tube, so as to protect the operating state of the air conditioner while ensuring the dehumidification effect of the air conditioner, avoiding the increase in energy consumption and potential failures caused by the overwork of the air conditioner, and reflecting the intelligent decision-making and self-protection capabilities of the air conditioner under complex working conditions.

[0070] The air conditioner dehumidification method of the present invention adjusts the number of heat exchange flow paths participating in heat exchange in the indoor heat exchanger 1 and the air volume gear Q of the indoor fan, so that the air conditioner reduces unnecessary shutdown phenomena, can maintain an appropriate operating frequency to ensure the dehumidification ability, improves the operating reliability of the air conditioner, which not only helps to improve the performance of the air conditioner in the dehumidification mode, but also enhances the user experience, and further enhances the market competitiveness of the product.

[0071] When the heat exchange flow path of the indoor heat exchanger 1 is closed while the operating frequency of the compressor and the air volume gear of the indoor fan remain unchanged, it is equivalent to the indoor heat exchanger 1 becoming smaller. The reduction of the indoor heat exchanger 1 means that its heat exchange area becomes smaller, and the amount of heat that the refrigerant in the indoor heat exchanger 1 can absorb per unit time decreases. However, other components such as the compressor and the indoor fan still operate under the original working conditions, that is, the compressor still delivers refrigerant to the indoor heat exchanger 1 at the original operating frequency, and the amount of refrigerant entering the indoor heat exchanger 1 remains unchanged. This will result in insufficient heat absorption capacity of the refrigerant in the indoor heat exchanger 1 and inability to fully absorb the heat to complete the liquid-to-gas conversion. Therefore, the temperature of the refrigerant in the indoor heat exchanger 1 is relatively low, which causes the actual tube temperature of the heat exchange tube of the indoor heat exchanger 1 to also decrease accordingly. To ensure that the actual tube temperature of the heat exchange tube of the indoor heat exchanger 1 is not too low (the freezing temperature is 0 °C, and thermal expansion and contraction abnormal noises are likely to occur at this time), it is necessary to first increase the air volume gear of the indoor fan on the basis of ensuring that the operating frequency of the compressor does not decrease, so as to ensure that the actual tube temperature T 实管 is greater than or equal to the set tube temperature threshold T 设管 (the set tube temperature threshold T 设管 is recommended to be 4 °C here); when the air volume gear of the indoor fan has reached the maximum and the actual tube temperature T 实管 is less than the set tube temperature threshold T 设管 , it is necessary to control the operating frequency of the compressor to decrease or control the air conditioner to stop, so as to ensure that the indoor heat exchanger 1 does not freeze.

[0072] Increasing the air volume gear of the indoor fan can increase the air flow rate passing through the indoor heat exchanger 1, which will directly affect the actual tube temperature of the heat exchange tube of the indoor heat exchanger 1 (that is, the evaporator). The specific reasons are as follows:

[0073] (1) Increase heat exchange efficiency: An increase in air velocity means that more heat can be absorbed by the indoor heat exchanger 1 per unit time, which helps to increase the rate of conversion of the refrigerant from liquid to gas, thus preventing the evaporation temperature of the indoor heat exchanger 1 from being too low.

[0074] (2) Prevent frosting: In the dehumidification or refrigeration mode, if the surface temperature of the indoor heat exchanger 1 is lower than the dew point temperature of the air, the water vapor in the air will condense into water droplets and even form a frost layer in extremely low temperatures. Increasing the fan speed of the indoor unit can accelerate air circulation, reduce the time for water vapor to condense on the surface of the indoor heat exchanger 1, thus avoiding or reducing the formation of the frost layer and keeping the evaporation temperature within a reasonable range.

[0075] (3) Improve air flow distribution: Increasing the fan speed of the indoor unit can ensure a more uniform air flow distribution on the surface of the indoor heat exchanger 1, avoiding local temperatures being too low, which may cause frosting or icing in some areas of the indoor heat exchanger 1 while other areas have higher temperatures. This uneven temperature distribution will reduce the dehumidification and refrigeration efficiency.

[0076] (4) Maintain the dry-wet balance on the surface of the indoor heat exchanger 1: The indoor heat exchanger 1 evaporates the refrigerant by absorbing heat from the air, and increasing the air flow speed helps to maintain the dry-wet balance on the surface of the indoor heat exchanger 1, preventing excessive humidity from condensing too quickly on the surface of the indoor heat exchanger 1, which may cause the surface temperature of the indoor heat exchanger 1 to drop suddenly.

[0077] (5) Avoid unstable compressor operation: An excessively low evaporation temperature may also cause the suction temperature of the compressor to be too low, thus affecting the operation stability of the compressor. Increasing the fan speed of the indoor unit to maintain a reasonable evaporation temperature helps to keep the entire refrigeration system operating stably.

[0078] In summary, increasing the fan speed of the indoor unit can optimize the heat exchange process between the air and the indoor heat exchanger 1, avoid problems such as frosting and performance degradation of the indoor heat exchanger 1 caused by too low surface temperature of the indoor heat exchanger 1, thus improving the dehumidification efficiency of the air conditioner while ensuring the stability and reliability of the air conditioner.

[0092] The computer program stored on the computer-readable storage medium is the core of implementing the air conditioner dehumidification method of the present invention. These computer programs contain specific algorithms and instructions that can guide the processor to analyze environmental data and air conditioner data, adjust the operating parameters of the air conditioner, and optimize the dehumidification effect.
