[0039] In view of the low comfort level of the air conditioner when the air outlet blows directly at the user in the related art, the embodiments of the present invention provide an air conditioner operation control method, device and air conditioner.

[0040] In order to improve the comfort level of the air conditioner when the air outlet blows directly at the user, the general idea of the embodiments of the present invention is: by coordinately controlling the operating frequency of the compressor in the air conditioner and the rotational speed of the first blower that provides the air outlet, to achieve the dynamic change of the air conditioner air supply and the constant air outlet temperature, so as to improve the comfort level when the air conditioner air outlet blows directly.

[0041] To make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0042] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above accompanying drawings are used to distinguish similar objects, and do not necessarily have to be used to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present invention described here can be implemented in an order different from those illustrated or described here. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these process, method, product or device.

[0043] Next, in conjunction with the accompanying drawings and with reference to specific embodiments, the air conditioner operation control method provided by the embodiments of the present invention will be described in detail.

[0044] An air conditioner operation control method provided by an embodiment of the present invention can be applied to an integrated air conditioner. For example, it can be applied to portable air conditioners, mobile air conditioners, window air conditioners, etc., which are used for local cooling or heating.

[0045] Refer to Figure 1 As shown, the integrated air conditioner includes: a compressor, a first fan for providing air outlet, and a second fan for providing air inlet. The first fan is equivalent to the indoor fan of a common room air conditioner, and the second fan is equivalent to the outdoor fan of a common room air conditioner. For portable air conditioners, mobile air conditioners, etc., the air outlet of the first fan must directly blow on the user to achieve an ideal local cooling and heating effect. Therefore, the air conditioner operation control method provided by the embodiments of the present invention is particularly suitable for portable air conditioners.

[0046] The integrated air conditioner may further include a human-machine interaction device and a main control device. Specifically, the main control device is connected to the first fan, the second fan, the compressor, and the human-machine interaction device to realize the first fan, the second fan, the compressor, and the human-machine interaction device. It should be understood that for other types of air conditioners such as room air conditioners, the air conditioner operation control method provided by the embodiments of the present invention can also be used.

[0047] Refer to Figure 2 As shown, the air conditioner operation control method provided by the embodiments of the present invention includes the following steps S201 - S202:

[0048] S201. Control the first fan to periodically change its speed according to a speed fluctuation curve.

[0049] S202. During the process of the first fan periodically changing its speed according to the speed fluctuation curve, synchronously control the compressor to periodically change its operating frequency according to a frequency fluctuation curve; wherein, the frequency fluctuation curve and the speed fluctuation curve have the same fluctuation period, and the frequency fluctuation curve has a positive phase difference relative to the speed fluctuation curve.

[0050] It can be understood that in the embodiments of the present invention, steps S201 and S202 should be executed synchronously, rather than executing step S202 after step S201 is completed.

[0051] Under a certain preset operation mode, steps S201 - S202 can be triggered to execute. By step S201, the speed of the first fan is dynamically changed, thereby increasing the dynamic effect of the air conditioner's air supply and improving the user's comfort and user experience.

[0052] Meanwhile, due to the dynamic change of the wind speed of the first fan, the heat exchange of the evaporator will change. When the wind speed decreases, the heat exchange of the evaporator decreases, the temperature of the evaporator also decreases, and the outlet air temperature will also decrease; when the wind speed increases, the heat exchange of the evaporator increases, the temperature of the evaporator also increases, and the outlet air temperature will also increase. As a result, the outlet air temperature of the air conditioner will change with the change of the wind speed of the first fan, affecting the user's adaptability.

[0053] In the embodiment of the present invention, through step S202, the running frequency of the compressor is synchronously adjusted following the dynamic change of the wind speed of the first fan. Since the running frequency of the compressor also changes with the rotation speed of the first fan, when the running frequency of the compressor decreases, the temperature of the evaporator will increase; when the running frequency of the compressor increases, the temperature of the evaporator will decrease. Therefore, synchronously controlling the dynamic change of the running frequency of the compressor can offset the influence of the wind speed change, making the outlet air temperature stable.

[0054] Furthermore, since the response from the change of the running frequency of the compressor to the change of the temperature of the evaporator is relatively slow and there is a certain delay, by setting a positive phase difference of the frequency fluctuation curve relative to the rotation speed fluctuation curve, the change of the frequency of the compressor has a certain lead change time relative to the change of the rotation speed of the first fan, so that the change of the temperature of the evaporator is consistent with the change of the rotation speed of the first fan, thereby further improving the stability of maintaining the outlet air temperature.

[0055] For example, the air conditioner is pre-configured with multiple preset operation modes, and the operations of steps S201 to S202 correspond to one of the operation modes. For example: the first operation mode, when the first operation mode is started based on a user instruction, steps S201 to S202 are triggered to be executed to periodically change the rotation speed of the first fan and the running frequency of the compressor, so as to realize the dynamic change of the wind speed and maintain the stability of the outlet air temperature. When starting other operation modes different from the first operation mode, the execution of steps S201 to S202 is terminated.

[0056] In some embodiments, both the rotation speed fluctuation curve and the frequency fluctuation curve can be pre-configured as a unique fluctuation curve. For an air conditioner configured with multiple gears, the rotation speed fluctuation curve and the frequency fluctuation curve can be pre-configured one by one for different gears of the air conditioner. According to the current gear of the air conditioner, the corresponding rotation speed fluctuation curve and frequency fluctuation curve are matched.

[0057] Different from the above embodiments, the rotation speed fluctuation curve and the frequency fluctuation curve may not be pre-configured. Before executing steps S201 and S202, a rotation speed fluctuation curve can be configured for the first fan and a frequency fluctuation curve can be configured for the compressor.

[0058] Configure the rotational speed fluctuation curve and the frequency fluctuation curve, which can specifically include the following steps: Obtain the current set rotational speed of the first fan and the current set frequency of the compressor; According to the current set frequency of the compressor and the current set rotational speed of the first fan, configure the frequency fluctuation curve for the compressor and configure the rotational speed fluctuation curve for the first fan.

[0059] Among them, the current set rotational speed of the first fan and the current set frequency of the compressor can be obtained based on the user instruction generated by the user operation. Here, the user instruction can be the user instruction when starting the first operation mode (for example, the first operation mode can be named as the comfort mode, the natural mode, etc.).

[0060] Specifically, the air conditioner is pre-configured with multiple gears, and the set rotational speed and the set frequency are pre-set for each gear one by one. Thus, according to the gear information carried in the start instruction or the gear shift instruction for the air conditioner, the rotational speed of the first fan and the frequency of the compressor are set. The first fan will operate at the set rotational speed corresponding to the current gear, and the compressor will work at the set frequency. Based on the user instruction to start the first operation mode, it is triggered to obtain the set frequency corresponding to the current gear, and it is triggered to obtain the set rotational speed corresponding to the current gear. Thus, when receiving the user instruction for starting the first operation mode, the current set rotational speed of the first fan and the current set frequency of the compressor are obtained.

[0061] Specifically, the one-to-one correspondence relationship between the gears of the air conditioner, the set rotational speed of the first fan, and the set frequency of the compressor is shown in Table 1 below:

[0062] Table 1

[0063]

[0064] In an embodiment, in order to improve the safety of the air conditioner, the current set rotational speed of the first fan and the current set frequency of the compressor are not only related to the user instruction, but also related to information such as the ambient temperature of the environment where the air conditioner is located.

[0065] Specifically, in response to the user instruction, obtain at least one-dimensional frequency limit parameter of the air conditioner; According to the frequency limit parameter and the user instruction, determine the current set rotational speed of the first fan and the current set frequency of the compressor.

[0066] Among them, the frequency limit parameter includes one or more of the temperature of the environment where the air conditioner is located, the input current of the air conditioner, the input voltage, etc.

[0067] For each dimension of the frequency limit parameter, determine the frequency limit parameter range where the dimension of the frequency limit parameter is located; use the frequency limit corresponding to the frequency limit parameter range as the current set frequency of the compressor; obtain the fan speed corresponding to the frequency limit as the current set speed of the first fan. If each dimension of the obtained frequency limit parameter does not belong to the frequency limit parameter range, then use the frequency corresponding to the gear set by the user instruction as the current set frequency of the compressor, and use the fan speed corresponding to the gear set by the user instruction as the current set speed of the first fan.

[0068] Taking the ambient temperature as an example, obtain the ambient temperature of the environment where the air conditioner is located; determine the current set speed of the first fan and the current set frequency of the compressor according to the ambient temperature and the user instruction.

[0069] Among them, determine the frequency limit temperature range where the ambient temperature is located; use the frequency limit corresponding to the frequency limit temperature range as the current set frequency of the compressor, and use the fan speed corresponding to the frequency limit as the current set speed of the first fan. If the ambient temperature is not within any frequency limit temperature range, then use the frequency corresponding to the gear set by the user instruction as the current set frequency of the compressor, and use the fan speed corresponding to the gear set by the user instruction as the current set speed of the first fan.

[0070] After obtaining the current set frequency of the compressor and the current set speed of the first fan, configure a frequency fluctuation curve for the compressor and a speed fluctuation curve for the first fan according to the current set frequency of the compressor and the current set speed of the first fan.

[0071] Specifically, the curve composition elements can be determined according to the current set frequency and the current set speed; use the curve composition elements to configure a frequency fluctuation curve for the compressor and a speed fluctuation curve for the first fan.

[0072] For the speed fluctuation curve, at least one dimension of curve composition elements for configuring the speed fluctuation curve can be determined according to the current set speed of the first fan. Among them, the curve composition elements of the speed fluctuation curve include: curve type, a first fluctuation period positively correlated with the current set speed, and a first change amplitude positively correlated with the current set speed.

[0073] It should be understood that with reference to Figure 3 and Figure 4As shown, for the curve type and the first fluctuation period of the rotational speed fluctuation curve, they can be the only fixed values set in advance. That is, regardless of the current set rotational speed, the only pre-set curve type and the only fluctuation period are adopted. At this time, only the first change amplitude is determined according to the current set rotational speed. It is also possible to determine each dimensional curve composition element for configuring the rotational speed fluctuation curve according to the current set rotational speed, that is: the curve type, the first fluctuation period, and the first change amplitude.

[0074] Specifically, for the frequency fluctuation curve, at least one dimensional curve composition element for configuring the frequency fluctuation curve is determined according to the current set frequency of the compressor. Among them, the curve composition elements of the frequency fluctuation curve include: the curve type, the second fluctuation period that is positively correlated with the current set frequency, and the second change amplitude that is positively correlated with the current set frequency.

[0075] It should be understood that referring to Figure 3 and Figure 4 As shown, for the curve type and the second fluctuation period of the frequency fluctuation curve, they can both be the only fixed values set in advance, that is, regardless of the current set frequency, the only pre-set curve type and the only fluctuation period are adopted. It is also possible to determine each dimensional curve composition element for configuring the frequency fluctuation curve according to the current set frequency, that is: the curve type, the second fluctuation period, and the second change amplitude.

[0076] It should be noted that the first fluctuation period and the second fluctuation period need to be kept consistent to achieve the synchronous and coordinated control of the operating frequency of the compressor of the air conditioner and the rotational speed of the first fan. The specific values of the first fluctuation period and the second fluctuation period can be 5s - 120s. It should be understood that the fluctuation period should not be too short. If it is too short, the sound of the wind speed change is too obvious, affecting the user experience; its change period should not be too long either. If it is too long, the user will not feel the dynamic effect of the wind speed, and it will also cause the wind speed of the first fan and the operating frequency of the compressor to stay in a lower range for a long time, resulting in insufficient cooling capacity during this period and affecting the user experience. When the current set frequency is relatively high, the fluctuation period can be appropriately lengthened to avoid the compressor or the fan from changing the frequency too quickly and affecting the temperature stability. That is: the higher the set frequency, the longer the fluctuation period.

[0077] To further improve the temperature stability, the rotational speed fluctuation curve and the frequency fluctuation curve adopt the same curve type. Specifically, referring to Figure 3 As shown, the curve types of the rotational speed fluctuation curve and the frequency fluctuation curve are both triangular wave curves, so that the rotational speed of the first fan and the operating frequency of the compressor both increase uniformly to the maximum value and then decrease uniformly to the minimum value, and this is repeated continuously. Referring to Figure 4As shown, the curve types of the rotational speed fluctuation curve and the frequency fluctuation curve can also be the same sine wave curve, so that when the rotational speed of the first fan and the operating frequency of the compressor change to near the maximum or minimum value, the change will be relatively slow and will stay near the maximum or minimum value for a relatively long time.

[0078] Of course, the curve types are not limited to the above examples and can also be set to other curve types according to actual needs. For example, the curve within a fluctuation period is composed of a triangular wave curve and a sine wave curve to achieve a more complex and variable wind speed change, and the wind speed dynamic effect is more natural. For the curve type, when the set rotational speed and frequency are relatively high, a triangular wave curve graph similar to Figure 3 can be adopted, and the entire wind speed change process will be relatively stable; when the set rotational speed and frequency are relatively low, a Figure 4 sine wave curve graph can be adopted, and the wind speed change is more gentle.

[0079] It should be understood that if the change range of the wind speed of the first fan and the change range of the operating frequency of the compressor are too small, the user cannot feel the dynamic effect of the wind speed; if they are too large, the output capacity fluctuates greatly, which will also affect the user experience. Based on this, the first change range of the rotational speed fluctuation curve is configured to be 10% - 60% of the current set rotational speed, and the second change range of the frequency fluctuation curve can be configured to be 10% - 60% of the current set frequency. Among them, if the current set rotational speed and the current set frequency are relatively low, in order to make the air output relatively gentle, the first change range and the second change range can be set relatively small; if the current set rotational speed and the current set frequency are relatively high, a larger first change range and second change range need to be set to increase the dynamic effect of the air output.

[0080] In the embodiments of the present invention, a one-to-one correspondence between the change range and the set rotational speed can be established in advance, so that according to the obtained current set rotational speed, the first change range for configuring the rotational speed fluctuation curve can be matched. A one-to-one correspondence between the change range and the set frequency can also be established in advance, so that according to the current set frequency, the second change range for configuring the frequency fluctuation curve can be matched. Referring to Table 2 below, an example of the correspondence between the first change range and the set rotational speed, and the second change range and the set frequency is illustrated:

[0081] Table 2.

[0082]

[0083] It should be understood that the data in Table 2 above are only illustrative data for understanding the technical solution of the present invention and do not limit the present invention.

[0084] Specifically, in order to configure the rotational speed fluctuation curve according to the current set rotational speed, the current set rotational speed is used as the rotational speed intermediate value of the rotational speed fluctuation curve; according to the rotational speed intermediate value and the first change amplitude, the maximum rotational speed value and the minimum rotational speed value are determined; the rotational speed fluctuation curve is configured by using the maximum rotational speed value, the rotational speed intermediate value, the minimum rotational speed value, the first fluctuation period and the curve type.

[0085] For example, if the current set rotational speed is 2800 r / min; referring to Table 2, the corresponding first change amplitude can be determined to be 20%. Then the maximum rotational speed value is 3360 r / min, and the minimum rotational speed value is 2240 r / min. Correspondingly, the current set frequency is determined to be 49 Hz, and then the second change amplitude corresponding to the current set frequency is determined to be 30%. According to the current set frequency and the second change amplitude of 30%, the maximum frequency value can be obtained as 63.7, and the minimum frequency value is 34.3.

[0086] The rotational speed fluctuation curve can be configured by using the minimum rotational speed value, the maximum rotational speed value, the curve type and the first fluctuation period determined by the foregoing process. The frequency fluctuation curve can be configured by using the minimum frequency value, the maximum frequency value, the curve type and the second fluctuation period determined by the foregoing process.

[0087] In the embodiment of the present invention, referring to Figure 3 and Figure 4 as shown, the positive phase difference can be configured as a value within the range of 3 to 30 s, that is, the leading change time of the frequency change of the compressor relative to the rotational speed change of the first fan is 3 to 30 s.

[0088] Specifically, the rotational speed value on the rotational speed fluctuation curve corresponds to the frequency value on the frequency fluctuation curve one by one. Among them, the maximum rotational speed value on the rotational speed fluctuation curve corresponds to the maximum frequency value on the frequency fluctuation curve. For any rotational speed value on the rotational speed fluctuation curve, such as rotational speed A, the operating frequency B corresponding to the rotational speed A can be advanced by 3 to 30 s relative to the rotational speed A. Thus, when the rotational speed of the first fan reaches the rotational speed A, the temperature of the heat exchanger just changes to correspond to the rotational speed A to stabilize the outlet air temperature. For example, the time when the operating frequency of the compressor reaches the maximum value is 3 to 30 s earlier than the time when the rotational speed of the first fan reaches the maximum rotational speed value.

[0089] Through the air conditioner operation control method introduced above, the air speed is dynamically changed during the operation of the air conditioner, and the temperature is stable during the dynamic change process of the air speed. Furthermore, the comfort of the air conditioner when the air blows directly is improved.

[0090] In a second aspect, based on the same inventive concept, the embodiment of the present invention further provides an air conditioner operation control device. Referring to Figure 1 as shown, the air conditioner includes a compressor and a first fan for providing outlet air. Referring toFigure 5 As shown, the operation control device includes:

[0091] A rotational speed control unit 501 for controlling the first fan to periodically change its rotational speed according to a rotational speed fluctuation curve;

[0092] A frequency control unit 502 for synchronously controlling the compressor to periodically change its operating frequency according to a frequency fluctuation curve during the process that the first fan periodically changes its rotational speed according to the rotational speed fluctuation curve; wherein, the frequency fluctuation curve and the rotational speed fluctuation curve have the same fluctuation period, and the frequency fluctuation curve has a positive phase difference relative to the rotational speed fluctuation curve.

[0093] Wherein, the frequency fluctuation curve and the rotational speed fluctuation curve have the same fluctuation period, and the frequency fluctuation curve has a positive phase difference relative to the rotational speed fluctuation curve.

[0094] In some embodiments, the operation control device further includes:

[0095] A data acquisition unit for acquiring the current set rotational speed of the first fan and the current set frequency of the compressor;

[0096] A curve configuration unit for configuring a frequency fluctuation curve for the compressor and a rotational speed fluctuation curve for the first fan according to the current set frequency and the current set rotational speed.

[0097] In some embodiments, the data acquisition unit is specifically configured to:

[0098] In response to a user instruction, acquire at least one-dimensional frequency limiting parameter of the air conditioner;

[0099] Determine the current set rotational speed of the first fan and the current set frequency of the compressor according to the at least one-dimensional frequency limiting parameter and the user instruction.

[0100] In some embodiments, the curve configuration unit includes:

[0101] An element determination sub-unit for determining curve composition elements according to the current set frequency and the current set rotational speed;

[0102] A configuration sub-unit for configuring a frequency fluctuation curve for the compressor and a rotational speed fluctuation curve for the first fan by using the curve composition elements.

[0103] In some embodiments, the curve composition elements of the rotational speed fluctuation curve include: curve type, a first fluctuation period positively correlated with the current set rotational speed, and a first change amplitude positively correlated with the current set rotational speed;
