[0002] Commercially available integrated air conditioners typically require temperature-based control. Due to space constraints, temperature sensors used to collect ambient temperature data are usually located at the air inlet of the condenser or evaporator. Because integrated air conditioners are used in complex environments, the temperature around the condenser or evaporator is unstable, and the temperature of the condenser or evaporator itself can affect the sensor's readings. This results in a significant discrepancy between the ambient temperature used to control the air conditioner and the actual ambient temperature, leading to noticeable control deviations in the integrated air conditioner. Summary of the Invention

[0003] This application provides a control method and an integrated air conditioner for an integrated air conditioner, which can solve the problem of significant control deviation in integrated air conditioners in related technologies.

[0024] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are protected by this application.

[0025] Commercially available integrated air conditioners typically require temperature-based control. Due to space constraints, temperature sensors used to collect ambient temperature data are usually located at the air inlet of the condenser or evaporator. Because integrated air conditioners are used in various scenarios (single-duct, double-duct, triple-duct, etc.), the temperature around the condenser or evaporator can be unstable in some situations. The temperature of the condenser or evaporator itself can also affect the sensor's readings, leading to a significant discrepancy between the ambient temperature used to control the air conditioner (i.e., the temperature measured by the sensor) and the actual ambient temperature. This results in noticeable control deviations in the integrated air conditioner.

[0026] In view of this, this application proposes a control method for an integrated air conditioner, which can determine the number of air ducts of the integrated air conditioner and control the integrated air conditioner with the corresponding ambient temperature under different numbers of air ducts, thereby reducing the control deviation of the integrated air conditioner.

[0027] To illustrate the technical solution of this application, specific embodiments are described below.

[0028] Figure 1 The illustration shows a schematic diagram of the implementation process of a control method for an integrated air conditioner provided in an embodiment of this application. This method is applicable to situations where it is necessary to reduce the control deviation of an integrated air conditioner.

[0029] An all-in-one air conditioner is a type of air conditioner that is different from a split-type air conditioner. In an all-in-one air conditioner, all components such as the condenser and evaporator are housed in a single, integrated unit. In some scenarios, all-in-one air conditioners can be used as portable air conditioners.

[0030] In embodiments of this application, an integrated air conditioner may include a condenser and an evaporator. The condenser is used to exchange heat between the high-temperature, high-pressure gaseous refrigerant and the air. The evaporator is used to change the refrigerant from a liquid state to a gaseous state, thereby absorbing heat from the air.

[0031] Specifically, Figure 2 A schematic diagram of an integrated air conditioner provided in this application is shown. The integrated air conditioner may include a condenser, a compressor, an evaporator, and an electronic expansion valve. The compressor is connected to both the evaporator and the condenser, and the electronic expansion valve is also connected to both. Gaseous refrigerant formed by heat exchange in the evaporator flows into the compressor. The compressor compresses the gaseous refrigerant into a high-pressure refrigerant gas, which is then forced into the condenser. After heat exchange in the condenser, the high-pressure refrigerant gas is throttled and depressurized by the electronic expansion valve, flowing back to the evaporator. This forms a system cycle of "condenser-electronic expansion valve-evaporator-compressor" within the integrated air conditioner.

[0032] In some implementations, such as Figure 2 As shown, the condenser, compressor, and evaporator can be connected via a four-way valve. The four-way valve can be used to change the flow direction of the gaseous refrigerant in the above system circulation, thereby enabling the integrated air conditioner to switch between cooling and heating modes.

[0033] In some implementations, such as Figure 2 As shown, a condenser fan can be installed on one side of the condenser to exhaust gas from the condenser. An evaporator fan can be installed on the other side of the evaporator to exhaust gas from the evaporator.

[0034] In some implementations, such as Figure 2As shown, filters can be installed between the condenser and the electronic expansion valve, and between the electronic expansion valve and the evaporator. These filters can absorb moisture and impurities from the piping, preventing cold or dirty blockages in the system's circulation.

[0035] In some implementations, such as Figure 2 As shown, a process tube can also be installed between the condenser and the electronic expansion valve, which can be used to charge refrigerant.

[0036] To facilitate the subsequent acquisition of ambient temperature, some implementation methods, such as Figure 2 As shown, ambient temperature sensors can be installed on both the condenser and evaporator sides. These sensors can be located at the air inlets of the condenser and evaporator to detect real-time ambient temperature. An exhaust temperature sensor can be installed on the compressor's exhaust pipe to detect the exhaust temperature. Pipeline temperature sensors can also be installed on the condenser and evaporator piping to detect real-time pipeline temperature.

[0037] It should be understood that Figure 2 This is merely a schematic diagram of the internal structure of an integrated air conditioner. In actual applications, an integrated air conditioner may include more or fewer components, and this application does not impose any restrictions on this.

[0038] It should be noted that, Figure 1 The control method shown can be executed by a processor, which can be integrated inside the integrated air conditioner or integrated into a separate control device, such as an electronic device. This electronic device can be a computer, smartphone, or other smart device, and can be used to control the integrated air conditioner. When the processor is integrated inside the integrated air conditioner, the integrated air conditioner can... Figure 1 The control method shown achieves autonomous control, and this application does not impose any restrictions on it.

[0039] Specifically, the control method for the integrated air conditioner may include the following steps S101 to S105.

[0040] Step S101: Obtain the first ambient temperature on the condenser side and the second ambient temperature on the evaporator side.

[0041] The first ambient temperature is the real-time ambient temperature on the condenser side, and the second ambient temperature is the real-time ambient temperature on the evaporator side. The processor can obtain the first ambient temperature through an ambient temperature sensor located on the condenser side, and the second ambient temperature through an ambient temperature sensor located on the evaporator side. Of course, the first and second ambient temperatures can also be obtained in other ways, such as by the user viewing the relevant temperatures and then inputting them; this application does not impose any restrictions on this.

[0042] Step S102: Calculate the first temperature difference between the first ambient temperature and the second ambient temperature.

[0043] Wherein, the first temperature difference is the absolute value of the difference between the first ambient temperature and the second ambient temperature.

[0044] Step S103: Determine the target function mode of the integrated air conditioner based on the temperature range where the first temperature difference is located.

[0045] In the embodiments of this application, the integrated air conditioner can be configured with multiple functional modes, each corresponding to a different number of ducts. The number of ducts refers to the total number of ducts connected to the integrated air conditioner. The ducts can be used to supply air to both the evaporator and condenser sides. When different numbers of ducts are connected, the integrated air conditioner operates in different functional modes. Different numbers of ducts will have different effects on the heat dissipation and thermal stability of the condenser or evaporator, causing different changes in the ambient temperature measured on the evaporator side and / or the condenser side. These changes can be represented by the magnitude of a first temperature difference. Therefore, the processor can determine the target functional mode of the integrated air conditioner based on the temperature range where the first temperature difference is located. The target functional mode is also the functional mode currently in which the integrated air conditioner operates among the aforementioned multiple functional modes.

[0046] Step S104: Determine the reference control temperature of the integrated air conditioner according to the target function mode.

[0047] The reference control temperature refers to the ambient temperature of the environment in which the integrated air conditioner is located, and it is also the ambient temperature used to control the integrated air conditioner.

[0048] In the embodiments of this application, the ambient temperatures measured on the evaporator side and / or the condenser side differ under different functional modes, and there may be a significant error between these temperatures and the ambient temperature of the integrated air conditioner. In this case, the processor can select a temperature closer to the ambient temperature of the integrated air conditioner from a first ambient temperature and a second ambient temperature, based on the target functional mode currently in which the integrated air conditioner is located, or it can determine an ambient temperature closer to the ambient temperature of the integrated air conditioner by processing the first and second ambient temperatures.

[0049] Step S105: Control the integrated air conditioner according to the reference control temperature.

[0050] In the embodiments of this application, the integrated air conditioner can be controlled to perform cooling, heating, and other operations based on a reference control temperature, and this application does not limit this. For example, the processor can determine whether the integrated air conditioner needs to cool or heat the current space based on the reference control temperature and the preset temperature set by the user for the current space. Accordingly, when the integrated air conditioner needs to cool, the processor can adjust the flow direction of the gaseous refrigerant by controlling the aforementioned four-way valve, so that the integrated air conditioner is in cooling mode and cools the current space. When the integrated air conditioner needs to heat, the processor can adjust the flow direction of the gaseous refrigerant by the aforementioned four-way valve, so that the integrated air conditioner is in heating mode and heats the current space.

[0051] In the embodiments of this application, the number of air ducts affects the heat dissipation and thermal stability of the condenser or evaporator differently. By calculating the first temperature difference between the first ambient temperature on the condenser side and the second ambient temperature on the evaporator side, and based on the temperature range of the first temperature difference, the target functional mode of the integrated air conditioner is determined. Based on the target functional mode, the reference control temperature of the integrated air conditioner is then determined. The reference control temperature in this embodiment can be determined by referring to the actual number of air ducts in the air conditioner, reducing the error between the reference control temperature and the actual ambient temperature. Furthermore, by controlling the integrated air conditioner based on the reference control temperature, the control deviation of the integrated air conditioner can be reduced.

[0052] For example, please refer to Figure 3 , Figure 3 A simplified schematic diagram of the integrated air conditioner's duct connection is shown. In the diagram, 31 is the air inlet on the evaporator side, 32 is the air outlet on the evaporator side; 33 is the air inlet on the condenser side, and 34 is the air outlet on the condenser side. A, B, and C are the ducts connected to the air outlet 32 ​​on the evaporator side, the air inlet 33 on the condenser side, and the air outlet 34 on the condenser side, respectively.

[0053] Combination Figure 3 The all-in-one air conditioner can be configured with single-duct, dual-duct, triple-duct, and ductless modes. Taking cooling mode as an example: In single-duct mode, the all-in-one air conditioner is connected to duct A and placed outdoors, delivering cool air into the room through duct A. In dual-duct mode, the all-in-one air conditioner is connected to ducts B and C and placed indoors; outdoor air exchanges heat with the condenser through duct C and is then exhausted outdoors through duct B. In triple-duct mode, the all-in-one air conditioner is connected to ducts A, B, and C, introducing air from different environments to the evaporator and condenser sides, suitable for off-grid homes. In ductless mode, the all-in-one air conditioner is not connected to any ducts.

[0054] First, the processor can obtain the first initial temperature on the condenser side when the integrated air conditioner is powered on, and / or the second initial temperature on the evaporator side when the integrated air conditioner is powered on.

[0055] The first initial temperature and the second initial temperature are the ambient temperatures measured on the condenser side and the evaporator side when the integrated air conditioner is powered on, respectively. They can be compared with the first ambient temperature and the second ambient temperature to determine the temperature changes on the condenser side and the evaporator side during the operation of the air conditioner.

[0056] In order to make the obtained first and second initial temperatures referential, in some embodiments, the processor can control the condenser fan and evaporator fan to run for a first preset time according to the first operating parameters after the integrated air conditioner is powered on, and after the condenser fan and evaporator fan have run for the first preset time, use the current temperature of the condenser as the first initial temperature, and use the current temperature of the evaporator as the second initial temperature.

[0057] Thus, on the one hand, the compressor is in a shut-off state during the first preset time period, which can avoid the heat interference generated by starting the compressor. On the other hand, collecting the initial temperature after starting the fan can allow the air to circulate quickly, eliminate temperature unevenness, and avoid the detected initial temperature being too high or too low.

[0058] In some implementations, after a first preset time period, the processor can control the compressor, condenser fan, and evaporator fan to run for a second preset time period according to the second operating parameters. That is, after the first preset time period, the processor can simultaneously start the compressor, condenser fan, and evaporator fan, allowing the integrated air conditioner to enter normal working condition.

[0059] It should be noted that the aforementioned first and second operating parameters may include parameters used to control the operation of the integrated air conditioner, such as operating power, operating current, and start-up time. The main difference between the second and first operating parameters is the addition of control parameters for the compressor. The second preset time and the first operating time can be the same or different; specific values ​​can be set based on experience.

[0060] After a second preset time period, the processor can execute the step of obtaining the first ambient temperature on the condenser side and the second ambient temperature on the evaporator side. That is, during the second preset time period, the integrated air conditioner is in normal working state, and the air conditioning control of the integrated air conditioner can be performed according to steps S101 to S105.

[0061] Specifically, in some implementations, in step S103, if the first temperature difference is less than or equal to the first temperature difference threshold, the target function mode of the integrated air conditioner is confirmed to be either the first function mode or the second function mode.

[0062] The number of ducts corresponding to the first functional mode is less than the number of ducts corresponding to the second functional mode. The first temperature difference threshold can be set based on experience, for example, 2℃.

[0063] At this time, in step S104, if the target function mode is the first function mode or the second function mode, the first ambient temperature is confirmed as the reference control temperature.

[0064] Specifically, the first functional mode can refer to the ductless mode. Please refer to [link / reference]. Figure 4 At this time, the condenser and evaporator of the integrated air conditioner exchange heat in the same space (space 41 in the figure). The first ambient temperature on the condenser side will not change significantly. That is, the first ambient temperature is basically the same as the actual ambient temperature of the environment where the integrated air conditioner is located. Therefore, the first ambient temperature can be confirmed as the reference control temperature.

[0065] The second functional mode can refer to the single-duct mode. Please refer to [link / reference]. Figure 5 At this time, the integrated air conditioner is placed in space 51, cooling or heating another space 52, but will not return air from space 52. Similarly, the first ambient temperature on the condenser side will not change significantly, that is, the first ambient temperature is basically the same as the actual ambient temperature of the environment where the integrated air conditioner is located, so the first ambient temperature can be confirmed as the reference control temperature.

[0066] Therefore, in the first or second functional mode, since the heat from the condenser has little impact on the detection accuracy of the ambient temperature sensor on the condenser side, the first ambient temperature detected on the condenser side is selected as the reference control temperature for the integrated air conditioner, which can reduce the control deviation of the integrated air conditioner.

[0067] In other implementations, in step S103, if the first temperature difference is greater than the first temperature difference threshold, the target functional mode is confirmed to be the third functional mode.

[0068] The number of ducts corresponding to the third functional mode is greater than that corresponding to the second functional mode. The second temperature difference threshold is greater than the first temperature difference threshold and can be set based on experience, for example, 5℃.

[0069] At this point, in step S104, if the target function mode is the third function mode, then the first initial temperature is confirmed as the reference control temperature.

[0070] Specifically, the third functional mode can refer to the dual-duct mode. Please refer to [link / reference]. Figure 6Taking an all-in-one air conditioner in cooling mode as an example, in the third function mode, the presence of the air duct reduces the airflow on the condenser side, causing the condenser surface temperature to rise. This heat transfer occurs through thermal radiation and other heat transfer methods to the ambient temperature sensor at the condenser air inlet, resulting in a deviation between the first ambient temperature detected by the condenser side and the actual ambient temperature of the environment where the all-in-one air conditioner is located. Furthermore, the evaporator side continuously cools down, lowering the second ambient temperature on the evaporator side, leading to a situation where the first temperature difference exceeds the second temperature difference threshold. The same logic applies to heating mode. In this case, the second ambient temperature measured on the evaporator side remains in a non-steady state. Considering the small rate of change in outdoor ambient temperature, the initial temperature detected upon power-on can be used as the reference control temperature. Controlling the all-in-one air conditioner based on this reference control temperature can reduce control deviation.

[0071] Accordingly, after controlling the integrated air conditioner according to the reference control temperature, the processor can return to the step of obtaining the first ambient temperature of the condenser and the second ambient temperature of the evaporator after detecting that the compressor has restarted.

[0072] In other words, the ambient temperature is only updated when the compressor is turned off and restarted; otherwise, the integrated air conditioner is controlled based on the reference control temperature.

[0073] In other embodiments, if the first temperature difference is greater than the first temperature difference threshold and less than the second temperature difference threshold, then the second temperature difference between the first initial temperature and the first ambient temperature, and the third temperature difference between the second initial temperature and the second ambient temperature are calculated, and the target functional mode is determined based on the temperature range in which the second temperature difference and the third temperature difference are located.

[0074] The second temperature difference is the absolute value of the difference between the first initial temperature and the first ambient temperature. The third temperature difference is the absolute value of the difference between the second initial temperature and the second ambient temperature.

[0075] Specifically, if the second temperature difference is less than or equal to the third temperature difference threshold, and the third temperature difference is greater than or equal to the fourth temperature difference threshold, then the processor can confirm that the target functional mode is the fourth functional mode.

[0076] The third temperature difference threshold is greater than the first temperature difference threshold but less than the second temperature difference threshold. Its specific value can be set based on experience, for example, 3℃. The fourth temperature difference threshold is greater than the second temperature difference threshold. Its specific value can be set based on experience, for example, 10℃.

[0077] At this point, in step S104, if the target function mode is the fourth function mode, then the first ambient temperature is confirmed as the reference control temperature.

[0078] Specifically, the fourth functional mode can refer to the ductless mode. The environments on the evaporator and condenser sides differ between the first and fourth functional modes. Please refer to [link / reference]. Figure 7 In the fourth functional mode, the evaporator and condenser sides are located in separate spaces. In this mode, the integrated air conditioner is not connected to ductwork; the evaporator side is indoors, and the condenser side is outdoors. Air that has undergone heat exchange with the condenser is discharged outdoors, and air that has undergone heat exchange with the evaporator is discharged indoors, which more effectively lowers the indoor temperature. Because there is no ductwork interference, the heat from the heat exchanger has a smaller impact on the accuracy of the temperature sensor. Therefore, the first ambient temperature detected by the condenser side can be selected as the reference control temperature to control the integrated air conditioner, helping to reduce control deviations.

[0079] In other implementations, if the second temperature difference is greater than the third temperature difference threshold, or the third temperature difference is less than the fourth temperature difference threshold, the processor can confirm that the target functional mode is the fifth functional mode.

[0080] At this time, in step S104, if the target function mode is the fifth function mode, the processor can confirm the second ambient temperature as the reference control temperature.

[0081] The number of ducts corresponding to the fifth functional mode is greater than the number of ducts corresponding to the third functional mode.

[0082] Specifically, the fifth functional mode can refer to the three-duct mode. Please refer to [link / reference]. Figure 8 In the fifth function mode, the integrated air conditioner can simultaneously meet the different cooling and heating needs of two independent spaces, 81 and 82. In this function mode, the ambient temperature sensor on the evaporator side is not affected by the heat from the heat exchanger. At this time, the second ambient temperature detected on the evaporator side is selected as the reference control temperature to control the integrated air conditioner, which can reduce the control deviation of the integrated air conditioner.

[0083] In the embodiments of this application, the functional mode of the air conditioner can be determined based on the first temperature difference, the second temperature difference, and the third temperature difference. The number of air ducts currently connected to the integrated air conditioner can be analyzed. Then, between the first ambient temperature, the second ambient temperature, and the first initial temperature, a temperature value close to the actual ambient temperature of the environment where the integrated air conditioner is located can be selected for the control of the integrated air conditioner. This can reduce the control deviation of the integrated air conditioner and ensure the operational stability and comfort of the integrated air conditioner.

[0084] For ease of understanding, Figure 9 A flowchart illustrating the process of an integrated air conditioner autonomously executing the aforementioned control method is shown. After receiving a start-up command, the integrated air conditioner can control the evaporator fan and condenser fan to run for a first operating time n, and during this process, collect the first initial temperature T on the condenser side. 冷0 and the second initial temperature T on the evaporator side蒸0 After the initial run time n, the system operates normally for a duration m. During this time, the integrated air conditioner can collect the initial ambient temperature T on the condenser side. 冷 and the second ambient temperature T on the evaporator side 蒸 Calculate the first temperature difference |T 冷 -T 蒸 |

[0085] If the first temperature difference is less than or equal to the first temperature difference threshold A, then the integrated air conditioner is confirmed to be in the first or second function mode, and the first ambient temperature T is set. 冷 Used as a reference control temperature.

[0086] If the first temperature difference is greater than the first temperature difference threshold A, then it is further determined whether the first temperature difference is greater than or equal to the second temperature difference threshold B. If the first temperature difference is greater than or equal to the second temperature difference threshold B, then it is confirmed that the integrated air conditioner is in the third function mode, and the first initial temperature T is set. 冷0 Used as a reference control temperature.

[0087] If the first temperature difference is greater than the first temperature difference threshold A and less than the second temperature difference threshold B, then the second temperature difference |T| needs to be calculated. 冷 -T 冷0 |and the third temperature difference|T 蒸 -T 蒸0 If the second temperature difference is less than or equal to the third temperature difference threshold a, and the second temperature difference is greater than or equal to the fourth temperature difference threshold b, then the integrated air conditioner is confirmed to be in the fourth function mode, and the first ambient temperature T is set. 冷 Used as a reference control temperature.

[0088] Otherwise, confirm that the integrated air conditioner is in the fifth function mode and set the second ambient temperature T. 蒸 Used as a reference control temperature.

[0089] It should be noted that, for the sake of simplicity, the aforementioned method embodiments are all described as a series of actions. However, those skilled in the art should understand that this application is not limited to the described order of actions, because according to this application, some steps can be performed in other orders.

[0090] like Figure 10 The diagram shown is a structural schematic of an integrated air conditioner control device 1000 provided in an embodiment of this application. The integrated air conditioner control device 1000 is configured on a processor.
