[0043] like Figure 1-Figure 5 As shown, the present invention provides an air conditioning control method for controlling an air conditioner, the air conditioner comprising a compressor 700, an outdoor heat exchanger 400, a throttling device 500 and an indoor heat exchanger 800, the indoor heat exchanger 800 having a plurality of heat exchange paths 801 arranged in parallel, the control method comprising:

[0044] S100, when the air conditioner is in cooling mode, determining whether the air outlet temperature of the air outlet of the indoor unit of the air conditioner is uniform.

[0045] To judge whether the air outlet temperature of the air outlet is uniform, the air outlet temperatures at different positions of the air outlet are needed for judgment. Generally, when the air outlet temperatures at multiple different positions are the same or have little difference, it can be determined that the air outlet temperature of the air outlet is uniform.

[0046] For example, multiple temperature monitoring points are respectively arranged on both sides and in the middle of the air outlet. When it is determined that the air outlet temperatures of multiple temperature monitoring points are the same, it is determined that the air outlet temperature of the indoor unit air outlet is uniform; when it is determined that the air outlet temperatures of any two monitoring points are different, it is determined that the air outlet temperature of the indoor unit air outlet is uneven.

[0047] S200, after determining that the outlet air temperature is uneven, determine whether the temperature difference between the highest flow path temperature and the lowest flow path temperature of the indoor heat exchanger is greater than a first preset difference.

[0048] Among them, the highest flow path temperature is the temperature of a branch flow path with the highest temperature among multiple heat exchange flow paths 801 in the indoor heat exchanger 800; the lowest flow path temperature is the temperature of a branch flow path with the lowest temperature among multiple heat exchange flow paths in the indoor heat exchanger 800.

[0049] Among them, the first preset difference is the difference data pre-stored in the controller of the air conditioner, which is used to determine whether the difference between the highest flow path temperature and the lowest flow path temperature exceeds the preset range. When the first difference between the highest temperature and the lowest flow path temperature is greater than the first preset difference, it means that the difference between the highest flow path temperature and the lowest flow path temperature in the indoor heat exchanger 800 exceeds the preset range, that is, the uneven distribution of heat exchange temperature in the indoor heat exchanger 800 exceeds the allowable range.

[0050] S300, when it is determined that the temperature difference between the highest flow path temperature and the lowest flow path temperature is greater than a first preset difference, adjusting the flow rate of at least one of the heat exchange flow path where the highest flow path temperature is located and the heat exchange flow path where the lowest flow path temperature is located.

[0051] Among them, when the temperature difference between the highest flow path temperature and the lowest flow path temperature is greater than the first preset difference, the uneven distribution of heat exchange temperature in the stacked indoor heat exchanger 800 exceeds the allowable range, and therefore it is necessary to adjust the refrigerant flow rate of the corresponding heat exchange flow path 801 in the indoor heat exchanger 800; such as increasing the flow rate of the heat exchange flow path 801 where the highest flow path temperature is located, or reducing the flow rate of the heat exchange flow path 801 where the lowest flow path temperature is located, so that the flow rate of the heat exchange flow path 801 in the heat exchanger tends to be uniform, thereby making the outlet air temperature uniform.

[0052] The flow rate of the heat exchange flow path 801 where the lowest flow path temperature is located can be adjusted alone, or the flow rate of the heat exchange flow path 801 where the highest flow path temperature is located can be adjusted alone, or both flow paths can be adjusted simultaneously.

[0053] It can be understood that after determining that the air outlet temperature of the indoor unit is uneven, the air conditioning control method determines whether it is necessary to adjust the flow of the heat exchange path 801 according to the maximum flow path temperature and the minimum flow path temperature of the indoor heat exchanger 800, and when the first difference between the maximum flow path temperature and the minimum flow path temperature is greater than the first preset difference, adjust the flow of at least one of the heat exchange path 801 where the maximum flow path temperature is located and the heat exchange path 801 where the minimum flow path temperature is located, so that the flow of the heat exchange path 801 in the heat exchanger tends to be uniform, and thus the air outlet temperature tends to be uniform.

[0054] In some embodiments, the indoor heat exchanger 800 is connected to the throttling device 500 with a first flow path 810, and multiple heat exchange flow paths 801 of the indoor heat exchanger 800 are all connected to the first flow path 810. A bypass flow path 820 is also arranged between the indoor heat exchanger 800 and the throttling device 500. The bypass flow path 820 includes multiple bypass branches 821 arranged in parallel, each bypass branch 821 is respectively connected to a heat exchange flow path 801, and a regulating valve 822 is arranged on each bypass flow path 820. In the cooling mode, the refrigerant flows from the compressor 700 to the outdoor heat exchanger 400, and then flows from the outdoor heat exchanger 400 to the throttling device 500, and then flows from the throttling device 500 to the indoor heat exchanger 800 through the first flow path 810. Generally, the regulating valve 822 on the bypass flow path 820 is in a closed state, and then the refrigerant flows from the indoor heat exchanger 800 to the compressor 700 to complete the cycle. S300, adjusting the flow rate of at least one of the heat exchange flow path where the highest flow path temperature is located and the heat exchange flow path where the lowest flow path temperature is located includes:

[0055] S310, opening the regulating valve 822 corresponding to the heat exchange flow path 801 with the highest flow path temperature until the first difference is less than or equal to the first preset difference.

[0056] Among them, the first preset difference is the difference data pre-stored in the controller of the air conditioner, which is used to determine whether the difference between the highest flow path temperature and the lowest flow path temperature exceeds the preset range. When the first difference between the highest temperature and the lowest flow path temperature is greater than the first preset difference, it means that the difference between the highest flow path temperature and the lowest flow path temperature in the indoor heat exchanger 800 exceeds the preset range, that is, the uneven distribution of heat exchange temperature in the indoor heat exchanger 800 exceeds the allowable range. Therefore, it is necessary to adjust the refrigerant flow rate of the heat exchange flow path 801 with the highest flow path temperature in the indoor heat exchanger 800; that is, open the regulating valve 822 of the bypass branch 821 connected to the heat exchange flow path 801, increase the refrigerant amount of the heat exchange flow path 801 through the bypass branch 821, and then reduce the difference between the highest flow path temperature and the lowest flow path temperature, so that the heat exchange temperature of the heat exchanger tends to be uniform, and then the air outlet temperature of the indoor unit tends to be uniform.

[0057] It can be understood that after determining that the air outlet temperature of the indoor unit is uneven, the air conditioning control method determines whether it is necessary to open the regulating valve 822 of the corresponding bypass branch 821 according to the maximum flow path temperature and the minimum flow path temperature of the indoor heat exchanger 800, and opens the regulating valve 822 corresponding to the maximum flow path temperature when the first difference between the maximum flow path temperature and the minimum flow path temperature is greater than the first preset difference, thereby adjusting the temperature difference between the heat exchange flow paths 801, and thus making the air outlet temperature tend to be uniform.

[0058] In some embodiments, S310, after opening the regulating valve 822 corresponding to the heat exchange flow path 801 with the highest flow path temperature, the air conditioning control method includes:

[0059] S400, adjusting the opening of the regulating valve 822 according to a first difference between the maximum flow path temperature and the minimum flow path temperature.

[0060] Among them, the first difference actually represents the flow distribution of the refrigerant at the highest flow path temperature and the lowest flow path temperature of the indoor heat exchanger 800. The larger the first difference, the greater the difference between the refrigerant amount in the flow path corresponding to the highest flow path temperature and the refrigerant flow at the lowest flow path temperature. Therefore, by adjusting the opening of the regulating valve 822 according to the first difference, the refrigerant flow rates of the two heat exchange flow paths 801 can be made to be the same, thereby making the heat exchange temperatures of the two heat exchange flow paths 801 tend to be the same.

[0061] In some embodiments, S400, adjusting the opening of the regulating valve 822 according to the first difference between the highest flow path temperature and the lowest flow path temperature includes:

[0062] S410, controlling the opening of the regulating valve 822 to increase as the first difference increases, and to decrease as the first difference decreases.

[0063] Among them, the larger the first difference is, the greater the difference between the refrigerant amount in the flow path corresponding to the highest flow path temperature and the refrigerant flow rate at the lowest flow path temperature. Setting the opening of the regulating valve 822 to be proportional to the first difference can adapt to the change of the first difference to adjust the opening of the regulating valve 822, thereby avoiding the regulating valve 822 from being too large or too small.

[0064] In some embodiments, S400, adjusting the opening of the regulating valve 822 according to the first difference includes:

[0065] S410: Determine a difference interval corresponding to the first difference.

[0066] Wherein, a plurality of difference intervals are pre-stored in the controller of the air conditioner. After the first difference is determined, the difference interval in which the first difference is located, ie, the difference interval corresponding to the first difference, can be determined.

[0067] S420, according to the difference interval, open the regulating valve 822 to an opening degree corresponding to the difference interval.

[0068] Among them, there are multiple regulating valve 822 opening values ​​in the controller of the air conditioner, and the multiple regulating valve 822 opening values ​​are made to correspond one by one to multiple difference intervals. After determining the difference interval corresponding to the first difference, the regulating valve 822 opening value corresponding to the difference interval can be determined, and then the regulating value of the regulating valve 822 is matched with the opening value corresponding to the corresponding difference interval.

[0069] In some embodiments, S100, determining whether the air outlet temperature of the air outlet of the indoor unit is uniform includes:

[0070] S110, determining whether the air outlet temperature is uniform according to a first air outlet temperature at the top of the air outlet, a second air outlet temperature at the middle of the air outlet, and a third air outlet temperature at the bottom of the air outlet.

[0071] Among them, whether the temperature of the air outlet is uniform is determined based on the air outlet temperatures at three positions: the top of the air outlet, the middle of the air outlet, and the bottom of the air outlet.

[0072] S120, when it is determined that there is a temperature difference between any two of the first outlet air temperature, the second outlet air temperature, and the third outlet air temperature, it is determined that the outlet air temperature is uneven;

[0073] S130: When it is determined that the first air outlet temperature, the second air outlet temperature, and the third air outlet temperature are equal to each other, it is determined that the air outlet temperature is uniform.

[0074] Specifically, specifically, calculate the difference between the first outlet air temperature and the second outlet air temperature, the difference between the second outlet air temperature and the third outlet air temperature, and the difference between the first outlet air temperature and the third outlet air temperature, and determine whether the three differences are 0. When it is determined that any one of the differences is not 0, it is determined that the outlet air temperature of the indoor unit air outlet is uneven; if it is determined that the three differences are all 0, that is, the first outlet air temperature, the second outlet air temperature and the third outlet air temperature are equal to each other, then it is determined that the outlet air temperature of the indoor unit air outlet is uniform.

[0075] In some embodiments, S100, determining whether the air outlet temperature of the air outlet of the indoor unit is uniform includes:

[0076] S110, determining whether the air outlet temperature of the air outlet is uniform according to a first air outlet temperature at the top of the air outlet, a second air outlet temperature at the middle of the air outlet, and a third air outlet temperature at the bottom of the air outlet.

[0077] S120, determining a maximum temperature difference between two of the first outlet air temperature, the second outlet air temperature, and the third outlet air temperature, and determining whether the outlet air temperature of the air outlet is uniform according to the maximum temperature difference and the second preset difference.

[0078] Among them, the second preset difference is the difference reference data pre-stored in the controller of the air conditioner, which is generally the maximum temperature difference allowed between various positions of the outlet air temperature. That is, when the temperature difference between any two positions of the air outlet exceeds the second preset difference, it can be determined that the outlet air temperature is uneven. When the maximum temperature difference between the positions of the outlet air temperature is less than the second preset difference, it can be determined that the current outlet air temperature is uniform.

[0079] S130: When the maximum temperature difference is greater than a second preset difference, determining that the air outlet temperature of the air outlet is uneven.

[0080] In some embodiments, the air conditioning control method further includes:

[0081] S500, when it is determined that the air outlet temperature of the air outlet of the indoor unit is uniform, the air conditioner is controlled to maintain the state of operation, and after a preset time period, it is determined again whether the air outlet temperature of the air outlet of the indoor unit is uniform.

[0082] The preset time period is a time length value pre-stored in the controller of the air conditioner and is used to periodically monitor the air outlet temperature of the indoor unit air outlet.

[0083] That is, when it is determined that the air outlet temperature of the indoor unit outlet is uniform, there is no need to adjust the state of the indoor heat exchanger 800, and the current state can be maintained.

[0084] In some embodiments, S200, determining whether to open the regulating valve 822 of the corresponding bypass branch 821 according to the maximum flow path temperature and the minimum flow path temperature of the indoor heat exchanger 800, further includes:

[0085] When it is determined that the first difference between the highest flow path temperature and the lowest flow path temperature is less than or equal to the first preset difference, the air conditioner is controlled to maintain the current state of operation.

[0086] Among them, the first preset difference is the difference data pre-stored in the controller of the air conditioner, which is used to determine whether the difference between the highest flow path temperature and the lowest flow path temperature exceeds the preset range. When the first difference does not exceed the preset range, it means that the current air outlet temperature unevenness is acceptable, and there is no need to adjust the refrigerant amount of the heat exchange flow path 801 of the indoor heat exchanger 800, and continue to maintain the current operating state.

[0087] In some embodiments, the present invention further provides an air conditioning control device 10, comprising an acquisition module 100, a judgment module 200 and a control module 300. The acquisition module 100 is used to acquire the air outlet temperature of the air outlet of the indoor unit of the air conditioner, the maximum flow path temperature of the indoor heat exchanger 800 and the minimum flow path temperature. The judgment module 200 is used to determine whether the air outlet temperature of the air outlet of the indoor unit is uniform when the air conditioner is in cooling mode. The judgment module 200 is used to determine whether the temperature difference between the maximum flow path temperature and the minimum flow path temperature of the indoor heat exchanger 800 is greater than a first preset difference after determining that the air outlet temperature is uneven. The control module 300 is used to adjust the flow rate of at least one of the heat exchange flow path 801 where the maximum flow path temperature is located and the heat exchange flow path 801 where the minimum flow path temperature is located when it is determined that the temperature difference between the maximum flow path temperature and the minimum flow path temperature is greater than the first preset difference.

[0088] In some embodiments, the present invention further provides an air conditioner, which may include components such as a processor 601 of one or more processing cores, a memory 602 of one or more computer-readable storage media, a power supply 603, and an input unit 604. The air conditioner also includes a compressor 700, an outdoor heat exchanger 400, a throttling device 500, and an indoor heat exchanger 800. The indoor heat exchanger 800 is provided with a plurality of parallel heat exchange flow paths 801. Those skilled in the art can understand that the structure of the above-mentioned air conditioner does not constitute a limitation on the air conditioner, and may include more or fewer components, or a combination of certain components, or different component arrangements. Among them:

[0089] The processor 601 is the controller of the air conditioner, and uses various interfaces and lines to connect various parts of the entire air conditioner. By running or executing software programs and / or modules stored in the memory 602, and calling data stored in the memory 602, the processor 601 performs various functions of the air conditioner and processes data, thereby monitoring the air conditioner as a whole. Optionally, the processor 601 may include one or more processing cores; preferably, the processor 601 may integrate an application processor 601 and a modem processor 601, wherein the application processor 601 mainly processes the operating system, user interface and computer programs, etc., and the modem processor 601 mainly processes wireless communications. It is understandable that the above-mentioned modem processor 601 may not be integrated into the processor 601.

[0090] The memory 602 can be used to store software programs and modules. The processor 601 executes various functional applications and data processing by running the software programs and modules stored in the memory. The memory may mainly include a program storage area and a data storage area, wherein the program storage area may store an operating system, a computer program required for at least one function (such as a sound playback function, an image playback function, etc.), etc.; the data storage area may store data created according to the use of the server, etc. In addition, the memory may include a high-speed random access memory, and may also include a non-volatile memory, such as at least one disk storage device, a flash memory device, or other volatile solid-state storage devices. Accordingly, the memory may also include a memory controller to provide the processor 601 with access to the memory.

[0091] The air conditioner also includes a power supply 603 for supplying power to each component. Preferably, the power supply 603 can be logically connected to the processor 601 through a power management system, so as to manage charging, discharging, and power consumption through the power management system.
