The application range of this kind of air conditioner is quite extensive, and it is suitable not only for people's fixed residences, but also for places where it is inconvenient to fixedly install the air conditioner or the fixed installation cost is too high, such as cars, temporary tents, simple mobile houses, basements, etc., so that consumers can have a comfortable environment with appropriate temperature whether they are in the above scenarios.

[0037] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. 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.

[0038] As a practitioner in the air conditioner field, frequency modulation control of the compressor according to the difference between the outlet air temperature and the set temperature is the most basic and common control method in the air conditioner field; the air conditioner detects the difference between the real-time outlet air temperature and the set temperature, and then according to different differences, the program will execute different compressor frequency control strategies. Most of these control methods for the compressor are variable frequency control strategies. Execute the corresponding control strategy according to the set operation mode of the air conditioner, that is, when the user sets the operation mode of the air conditioner, such as the cooling mode, the sleep mode or the air supply mode, after the air conditioner receives the operation mode instruction of the air conditioner, it executes the corresponding operation strategy. Most of these control methods for the compressor control method are fixed frequency control strategies.

[0039] In related solutions, the system configuration of a portable air conditioner makes it rely mainly on the parameters collected by the air outlet temperature thermistor during operation to execute control strategies. As a result, it is very difficult for a portable air conditioner to achieve stable temperature control accuracy, and this is also the reason for its relatively high operating energy consumption. In contrast, a household split air conditioner can achieve coordinated control through multiple system parameters and environmental parameters. This leads to the inability to obtain the system parameters of the portable air conditioner, directly resulting in the inability of the portable air conditioner to execute intelligent control strategies that require obtaining more system parameters. Therefore, it is necessary to obtain or predict the system parameters of the air conditioner through other means to improve the intelligence level of the control system of the portable air conditioner.

[0040] The system configuration of a portable air conditioner makes it rely mainly on the parameters collected by the air outlet temperature thermistor during operation to execute control strategies. In contrast, a household split air conditioner can achieve coordinated control through multiple system parameters and environmental parameters. This leads to the inability to obtain the system parameters of the current portable air conditioner. Many adaptive control algorithms require obtaining sufficient system parameters to execute. It is very difficult for a portable air conditioner that only executes control strategies by collecting air outlet temperature parameters to execute relatively complex adaptive control strategies. Therefore, it is necessary to obtain or predict the system parameters of the air conditioner through other means to improve the adaptive control ability of the control system of the portable air conditioner.

[0041] Considering that, looking at the control methods of portable air conditioners in related solutions, the feedback between the air conditioner and the environment mostly relies on the parameters collected by the air outlet temperature thermistor. This single feedback path makes it difficult for a portable air conditioner to achieve stable temperature control accuracy during use on the one hand. On the other hand, due to the single feedback parameter, the air conditioner cannot fully utilize the coordinated operation of the system actuators, and the operating energy consumption is high. Therefore, the solution of the present invention proposes a control method for a mobile air conditioner, specifically an adaptive control method for a portable air conditioner, to control by predicting the return air temperature of the evaporator of the air conditioner and combining the return air temperature of the evaporator of the air conditioner, which is beneficial to achieving stable temperature control accuracy during the use of the portable air conditioner.

[0042] According to an embodiment of the present invention, there is provided a control method for a mobile air conditioner, as Figure 1 shown in the schematic flow chart of an embodiment of the method of the present invention. The mobile air conditioner has a compressor, a condenser, and an evaporator. A blower is provided at the condenser, denoted as the condenser blower. A blower is provided at the evaporator, denoted as the evaporator blower. In the solution of the present invention, as Figure 1 shown, the control method of the mobile air conditioner includes: step S110 to step S130.

[0043] At step S110, when the mobile air conditioner runs for a first set time after being turned on, a set of operating parameters of the mobile air conditioner is obtained. Among them, a set of operating parameters of the mobile air conditioner includes: the target temperature of the mobile air conditioner, the operating gear of the evaporation fan, the temperature at the air outlet of the evaporator, i.e., the air outlet temperature of the evaporator, and the operating power of the compressor.

[0044] At step S120, based on the set of operating parameters of the mobile air conditioner obtained, the tube temperature of the condenser is determined according to the target temperature of the mobile air conditioner, the operating gear of the evaporation fan, the air outlet temperature of the evaporator, and the operating power of the compressor.

[0045] In some embodiments, in step S120, based on the set of operating parameters of the mobile air conditioner obtained, the tube temperature of the condenser is determined according to the target temperature of the mobile air conditioner, the operating gear of the evaporation fan, the air outlet temperature of the evaporator, and the operating power of the compressor, including: using a pre-trained condenser tube temperature prediction model, the tube temperature of the condenser is calculated according to the target temperature of the mobile air conditioner, the operating gear of the evaporation fan, the air outlet temperature of the evaporator, and the operating power of the compressor. Among them, the pre-trained condenser tube temperature prediction model is as follows: T 冷凝器管温 =α3T 设定运行温度 +β3B 运行风档 +γ3T 蒸发器出风温度 +δ3P 运行功率 +ξ3.

[0046] Among them, T 冷凝器管温 is the tube temperature of the condenser, T 设定运行温度 is the target temperature of the mobile air conditioner, B 运行风档 is the operating gear of the evaporation fan, T 蒸发器出风温度 is the air outlet temperature of the evaporator, P 运行功率 is the operating power of the compressor, and α3, β3, γ3, δ3, ζ3 are correction coefficients of the pre-trained condenser tube temperature prediction model.

[0047] In the solution of the present invention, a method and a prediction model for predicting the tube temperature of a portable air conditioner condenser are proposed. Among them, a method for predicting the tube temperature of a portable air conditioner condenser specifically refers to collecting the set operating temperature, operating wind speed information, evaporator outlet air temperature information, and operating power information during the operation of the air conditioner through an information collection module. After being processed by a central control model and a timing module, it is sent to a condenser tube temperature prediction module. The condenser tube temperature prediction module completes data calculation and generates a calculation result of the condenser tube temperature, which is fed back to the central control module for adaptive adjustment decision-making. A prediction model for predicting the tube temperature of a portable air conditioner condenser specifically refers to a condenser tube temperature prediction mathematical model stored in the condenser tube temperature prediction module. The specific form of this mathematical model is as follows:

[0048] T 冷凝器管温 =α3T 设定运行温度 +β3B 运行风档 +γ3T 蒸发器出风温度 +δ3P 运行功率 +ξ3.

[0049] Among them, T 冷凝器管温 is the condenser tube temperature, with the unit of °C. T 设定运行温度 is the set operating temperature of the air conditioner, with the unit of °C. B 运行风档 is the value corresponding to the set operating gear of the air conditioner evaporator fan. T 蒸发器出风温度 is the outlet air temperature collected by the evaporator outlet temperature sensor, with the unit of °C. P 运行功率 is the power of the air conditioner compressor, with the unit of W. α3, β3, γ3, δ3, ζ3 are correction coefficients of the condenser tube temperature prediction model, which are dimensionless parameters and have no specific meaning. Their values will vary according to the maximum cooling capacity, maximum air supply volume, compressor parameters, and air duct layout of the air conditioner. In the solution of the present invention, taking an air conditioner with a maximum cooling capacity of 700 W and a maximum air supply volume of 120 m 3 / h as an example, the correction coefficients α3, β3, γ3, δ3, ζ3 of its condenser tube temperature prediction model are -1.673, -0.152, 0.341, 0.121, and 25.331 respectively. Particularly, the coefficients of α3, β3, γ3, δ3, ζ3 listed here are for illustrative purposes of their example values and are not intended to limit the specific values of their values.

[0050] Figure 7 It is a verification schematic diagram of the measured condenser tube temperature and the predicted condenser tube temperature of a method for adaptive adjustment of a portable air conditioner. Figure 7 The shown is the verification schematic diagram of the measured condenser tube temperature and the predicted condenser tube temperature of the air conditioner in the embodiment. It can be seen that the result comparison between the condenser tube temperature calculated by the condenser tube temperature prediction mathematical model proposed in the solution application of the present invention and the measured condenser tube temperature is relatively consistent, which can meet the use requirements of the portable air conditioner.

[0051] At step S130, based on a set of operating parameters of the portable air conditioner obtained, according to the air outlet temperature of the evaporator, the target temperature of the portable air conditioner, and the pipe temperature of the condenser, or according to the air outlet temperature of the evaporator and the target temperature of the portable air conditioner, adjust the operating frequency of the compressor, adjust the operating air volume of the evaporator fan, and adjust the operating air volume of the condenser fan or the rotational speed of the condenser fan.

[0052] Specifically, Figure 5 FIG. is a schematic structural diagram of an embodiment of a control system for adaptive adjustment of a portable air conditioner. As Figure 5 shown, a portable air conditioner adaptive control system proposed by the solution of the present invention includes: a data acquisition module, a central control module, a condenser pipe temperature prediction module, and an actuator module. Figure 6 FIG. is a schematic logical framework diagram of an embodiment of a control system for adaptive adjustment of a portable air conditioner. In a portable air conditioner adaptive control system as Figure 6 shown, the data acquisition module is a section in the control system responsible for data acquisition, storage, and transmission. In the solution of the present invention, the data acquired by the data acquisition module includes but is not limited to the set operating temperature, operating air volume, air outlet temperature of the evaporator, and operating power.

[0053] Among them, the set operating temperature refers to the operating temperature set after the air conditioner is turned on and operated. In the solution of the present invention, the selectable range of the set temperature of the air conditioner is 16°C to 30°C, and the temperature setting accuracy is 1°C.

[0054] The operating air volume refers to the operating gear set for the evaporator fan of the air conditioner, and usually includes but is not limited to air volume gear 1, air volume gear 2, air volume gear 3, and air volume gear 4, etc. In the solution of the present invention, after the system detects the set operating air volume of the air conditioner, the data acquisition module will convert the operating air volume into corresponding numerical information (for example, air volume gear 1 is recognized as the numerical value "1", air volume gear 2 is recognized as the numerical value "2", air volume gear 3 is recognized as the numerical value "3", and air volume gear 4 is recognized as the numerical value "4").

[0055] The air outlet temperature of the evaporator refers to the dry bulb temperature of the air at the air outlet of the evaporator in the air conditioner. In the solution of the present invention, the air outlet temperature information of the evaporator is collected by a temperature sensor arranged at the air outlet of the evaporator, and the temperature sensor sends the collected air outlet temperature information to the data acquisition module.

[0056] The operating power refers to the real-time power parameter during the operation of the air conditioner. In the solution of the present invention, after the system obtains the power parameter of the compressor module by detecting the power supply module, it sends the information of the power parameter of the compressor operation to the data acquisition module.

[0057] In asFigure 6 In a portable air conditioner adaptive control system shown, the central control module is the core control section of the air conditioner. In the solution of the present invention, the central control module is responsible for receiving the data information transmitted by the data acquisition module, activating the timing module, completing the identification, processing, and transmission of the data information, then sending the processed data to the condenser tube temperature prediction module, and finally, according to the calculation result of the condenser tube temperature prediction module, activating the actuator module to complete the corresponding adaptive adjustment instruction.

[0058] In the solution of the present invention, the identification and processing of the data information by the central control module refer to: identifying the set operating temperature information of the air conditioner and converting the set operating temperature information into corresponding numerical information. A condenser tube temperature prediction mathematical model proposed in the solution of the present invention is a numerical calculation model, and its calculation process is a calculation and processing process performed on numerical characters, and it cannot perform calculations on other formats of characters, such as text strings, symbol strings, etc. Therefore, it is necessary to process the set operating temperature information of the air conditioner, such as identifying the "set temperature 16°C" as the numerical "16" string, the "set temperature 18°C" string as the numerical "18" string, the "set temperature 20°C" string as the numerical "20" string, the "set temperature 25°C" string as the numerical "25" string, and so on. The purpose and function of the conversion are to convert the "set operating temperature information" in the air conditioner system parameters into a numerical format that the condenser tube temperature prediction mathematical model can execute calculations on, so that the condenser tube temperature parameters required by the control method of the solution of the present invention can be obtained through the calculation of this model.

[0059] Identifying the operating wind speed information of the air conditioner evaporator fan and converting the operating wind speed information into corresponding numerical information. A condenser tube temperature prediction mathematical model proposed in the solution of the present invention is a numerical calculation model, and its calculation process is a calculation and processing process performed on numerical characters, and it cannot perform calculations on other formats of characters, such as text strings, symbol strings, etc. Therefore, it is necessary to process the operating wind speed information of the air conditioner, such as identifying the "wind speed 1" as the numerical "1" string, the "wind speed 2" as the numerical "2" string, the "wind speed 3" as the numerical "3" string, and the "wind speed 4" as the numerical "4" string. The purpose and function of the conversion are to convert the "operating wind speed information" in the air conditioner system parameters into a numerical format that the condenser tube temperature prediction mathematical model can execute calculations on, so that the condenser tube temperature parameters required by the control method of the solution of the present invention can be obtained through the calculation of this model.

[0060] Identify the outlet air temperature information collected by the evaporator outlet temperature sensor, and convert the temperature information into numerical information that can be processed by the central control module. A condenser tube temperature prediction mathematical model proposed by the solution of the present invention is a numerical calculation model, and its calculation process is a calculation and processing process performed on numerical characters, and cannot perform calculations on other formats of characters, such as text strings, symbol strings, etc. Therefore, it is necessary to process the outlet air temperature information of the air conditioner. For example, identify "outlet air temperature 10°C" as the numerical "10" string, identify the string "outlet air temperature 15°C" as the numerical "15" string, identify the string "outlet air temperature 28°C" as the numerical "28" string, identify the string "outlet air temperature 30°C" as the numerical "30" string, and so on. The purpose and function of the conversion are to convert the "outlet air temperature information" in the air conditioner system parameters into a numerical format that the condenser tube temperature prediction mathematical model can perform calculations on, so that the condenser tube temperature parameters required by the control method of the solution of the present invention can be obtained through the calculation of this model.

[0061] Identify the power parameter information of the compressor module obtained by the power supply module, and convert the power information into numerical information that can be processed by the central control module. A condenser tube temperature prediction mathematical model proposed by the solution of the present invention is a numerical calculation model, and its calculation process is a calculation and processing process performed on numerical characters, and cannot perform calculations on other formats of characters, such as text strings, symbol strings, etc. Therefore, it is necessary to process the compressor operating power information obtained by the air conditioner battery module. For example, identify "compressor operating power 100W" as the numerical "100" string, identify the string "compressor operating power 150W" as the numerical "150" string, identify the string "compressor operating power 280W" as the numerical "280" string, identify the string "compressor operating power 300W" as the numerical "300" string, and so on. The purpose and function of the conversion are to convert the "compressor operating power information" in the air conditioner system parameters into a numerical format that the condenser tube temperature prediction mathematical model can perform calculations on, so that the condenser tube temperature parameters required by the control method of the solution of the present invention can be obtained through the calculation of this model.

[0062] In Figure 6 In a portable air conditioner adaptive control system as shown, the condenser tube temperature prediction module receives the information of the data acquisition module processed by the central control module and the timing module, calculates the air conditioner condenser tube temperature through the condenser tube temperature prediction model, and feeds back the calculation result to the central control module. The central control module determines whether to execute the adaptive adjustment instruction according to the feedback result.

[0063] In Figure 6In a portable air conditioner adaptive control system shown, the actuator module refers to an actuator that can complete adaptive control adjustment. In the solution of the present invention, the actuator module refers to a compressor, a condenser fan, and an evaporator fan.

[0064] The solution of the present invention proposes a portable air conditioner adaptive control method, which does not require additional sensors and can be completed only by using the system parameters of the portable air conditioner. Through corresponding control strategies, the return air temperature of the air conditioner evaporator (i.e., the condenser pipe temperature) can be predicted, which can reflect the average temperature of the air conditioner environment to a certain extent and is beneficial to achieving stable temperature control accuracy during the use of the portable air conditioner.

[0065] In some embodiments, in step S130, based on a set of operating parameters of the mobile air conditioner obtained, according to the outlet air temperature of the evaporator, the target temperature of the mobile air conditioner, and the pipe temperature of the condenser, or according to the outlet air temperature of the evaporator and the target temperature of the mobile air conditioner, the specific process of adjusting the operating frequency of the compressor, adjusting the operating air volume of the evaporator fan, and adjusting the operating air volume of the condenser fan or the rotational speed of the condenser fan is as follows in the following exemplary description.

[0066] Specifically, Figure 8 It is a schematic diagram of the control logic of the adaptive control strategy of an embodiment of a method for adaptive adjustment of a portable air conditioner. As Figure 8 shown, the control method for adaptive adjustment of a portable air conditioner proposed by the solution of the present invention is a series of control strategies and execution actions jointly participated by a data acquisition module, a central control module, a timing module, a condenser pipe temperature prediction module, and an actuator module. As Figure 8 shown, the control method for adaptive adjustment of a portable air conditioner proposed by the solution of the present invention includes:

[0067] Step 1: First, after the air conditioner is turned on and runs, the data acquisition module collects the set operating temperature, operating air volume information, evaporator outlet air temperature information, and compressor operating power information of the air conditioner. Here, the first data information judgment is completed: If the data acquisition module recognizes and judges the operating parameters of the air conditioner compressor, the judgment method here is to identify the compressor operating power of the air conditioner through the data acquisition module. For example, when the compressor operating power P 运行功率 ≤10, it is considered that the compressor is not started. Then, the central control module starts to execute the adaptive control program. However, according to experimental data, in the initial stage of the air conditioner starting and running, the system parameters such as the compressor operating power and the outlet air temperature of the air conditioner are in a fluctuating state, and it is not suitable for adaptive control in this stage.

[0068] Therefore, in the solution of the present invention, after the central control module starts to execute the adaptive control program, it first calls the timing module. The timing module starts timing after the central control module recognizes that the air conditioner starts running. When the running time of the air conditioner reaches the first set time Δt1, the data acquisition module acquires the first set of set running temperature parameters, running wind speed parameters, evaporator outlet air temperature parameters, and compressor running power parameters, and sends this set of parameters to the central control module. According to the actually measured data in the laboratory, the value range of the first set time Δt1 is 5 - 30 min. In the solution of the present invention, the preferred value of the first set time Δt1 is 15 min.

[0069] Step 2: After the central control module receives the first set of set running temperature parameters, running wind speed parameters, evaporator outlet air temperature parameters, and compressor running power parameters acquired by the above data acquisition module, according to the data processing method, it converts the set running temperature parameters, running wind speed parameters, evaporator outlet air temperature parameters, and compressor running power parameters into numerical information that the central control module can process, and then sends the numerical information of the relevant running parameters to the condenser tube temperature prediction module.

[0070] Step 3: The condenser tube temperature prediction module imports the numerical information of the relevant parameters sent by the central control module into the condenser tube temperature prediction mathematical model. The condenser tube temperature prediction mathematical model calculates the condenser tube temperature T of the air conditioner at this moment 冷凝器管温 , and feeds back the calculation result to the central control module.

[0071] Step 4: The central control module retrieves the set running temperature parameter T 设定运行温度 , the evaporator outlet air temperature T 蒸发器出风温度 fed back by the data acquisition module, and the condenser tube temperature T 冷凝器管温 fed back by the condenser tube temperature prediction module. According to the comparison results of the set running temperature parameter T 设定运行温度 , the evaporator outlet air temperature T 蒸发器出风温度 , and the condenser tube temperature T 冷凝器管温 fed back by the condenser tube temperature prediction module, it executes the adaptive adjustment control strategy.

[0072] The following combines Figure 2 a schematic flowchart of an embodiment of adjusting the running frequency of the compressor, the running wind speed of the evaporator fan, and the running wind speed or the rotation speed of the condenser fan in the method of the present invention shown, and further illustrates the specific process of adjusting the running frequency of the compressor, the running wind speed of the evaporator fan, and the running wind speed or the rotation speed of the condenser fan in step S130, including: steps S210 to S250.

[0073] Step S210: Determine the temperature difference between the outlet air temperature of the evaporator and the target temperature of the mobile air conditioner, and denote it as the outlet air temperature difference of the mobile air conditioner.

[0074] Step S220: If the outlet air temperature difference of the mobile air conditioner is greater than or equal to the first set temperature difference, perform a first adjustment on the operating frequency of the compressor, the operating air volume of the evaporator fan, and the operating air volume of the condenser fan or the rotational speed of the condenser fan according to the pipe temperature of the condenser. The first set temperature difference is, for example, 5°C.

[0075] In some embodiments, in step S220, performing a first adjustment on the operating frequency of the compressor, the operating air volume of the evaporator fan, and the operating air volume of the condenser fan or the rotational speed of the condenser fan according to the pipe temperature of the condenser includes any of the following first adjustment scenarios:

[0076] The first first adjustment scenario: If the pipe temperature of the condenser is greater than the first set pipe temperature, control the compressor to operate at the preset maximum frequency, control the operating air volume of the evaporator fan not to exceed the set medium-low air volume, and control the condenser fan to operate at the preset maximum rotational speed. The first set pipe temperature is, for example, 65°C.

[0077] The second first adjustment scenario: If the pipe temperature of the condenser is greater than the second set pipe temperature and less than or equal to the first set pipe temperature, control the compressor to operate at the preset maximum frequency, control the operating air volume of the evaporator fan not to exceed the set medium air volume, and control the condenser fan to operate at the preset maximum rotational speed. The second set pipe temperature is, for example, 60°C.

[0078] The third first adjustment scenario: If the pipe temperature of the condenser is less than or equal to the second set pipe temperature, control the compressor to operate at the preset maximum frequency, control the operating air volume of the evaporator fan not to exceed the set medium-high air volume, and control the condenser fan to operate at the preset maximum rotational speed. The second set pipe temperature is, for example, 60°C.

[0079] Specifically, as Figure 8 shown, a control method for adaptive adjustment of a portable air conditioner proposed by the solution of the present invention further includes: In step 4, the execution method of this adaptive adjustment control strategy is as follows:

[0080] Step 41: When T 蒸发器出风温度 -T 设定运行温度 ≥5°C, then perform the following judgment:

[0081] If T 冷凝器管温>65°C, the system considers that the condenser tube temperature is too high, and at this time the central control module executes the adaptive adjustment instruction 1. When the central control module executes the adaptive adjustment instruction 1, in this state, the central control module sends an instruction to the actuator module: (1) The actuator module controls the compressor to preferentially execute the high-frequency operation instruction. (2) The actuator module controls the evaporator fan speed not to exceed the medium-low speed (that is, if the evaporator fan speed is high speed, medium-high speed or medium speed at this time, it is preferentially adjusted to medium-low speed. If the evaporator fan speed is medium-low speed or low speed at this time, it remains at the original set speed). (3) The actuator module controls the condenser fan to preferentially operate at the maximum speed.

[0082] If 60°C < T 冷凝器管温 ≤65°C, the system considers that the heat exchange effect of the condenser is not good, and at this time the central control module executes the adaptive adjustment instruction 2. When the central control module executes the adaptive adjustment instruction 2, in this state, the central control module sends an instruction to the actuator module: (1) The actuator module controls the compressor to preferentially execute the high-frequency operation instruction. (2) The actuator module controls the evaporator fan speed not to exceed the medium speed (that is, if the evaporator fan speed is high speed or medium-high speed at this time, it is preferentially adjusted to medium speed. If the evaporator fan speed is medium speed, medium-low speed or low speed at this time, it remains at the original set speed). (3) The actuator module controls the condenser fan to preferentially operate at the maximum speed.

[0083] If T 冷凝器管温 ≤60°C, the system considers that there is still some margin in the heat exchange capacity of the condenser, and at this time the central control module executes the adaptive adjustment instruction 3. When the central control module executes the adaptive adjustment instruction 3, in this state, the central control module sends an instruction to the actuator module: (1) The actuator module controls the compressor to preferentially execute the high-frequency operation instruction. (2) The actuator module controls the evaporator fan speed not to exceed the medium-high speed (that is, if the evaporator fan speed is high speed at this time, it is preferentially adjusted to medium-high speed. If the evaporator fan speed is medium-high speed, medium speed, medium-low speed or low speed at this time, it remains at the original set speed). (3) The actuator module controls the condenser fan to preferentially operate at the maximum speed.

[0084] Step S230, if the air outlet temperature difference of the mobile air conditioner is greater than the second set temperature difference and less than the first set temperature difference, then according to the tube temperature of the condenser, a second adjustment is made to the operating frequency of the compressor, the operating speed of the evaporator fan, and the operating speed or the rotational speed of the condenser fan. Among them, the second set temperature difference is, for example, 1°C.

[0085] In some embodiments, in step S230, according to the pipe temperature of the condenser, a second adjustment is made to the operating frequency of the compressor, the operating gear of the evaporation fan, and the operating gear of the condensation fan or the rotational speed of the condensation fan, including any of the following second adjustment scenarios:

[0086] The first second adjustment scenario: If the pipe temperature of the condenser is greater than the first set pipe temperature, control the compressor to operate at a preset medium-high frequency, control the operating gear of the evaporation fan not to exceed the set medium-low gear, and control the condensation fan to operate at a preset maximum rotational speed. Wherein, the first set pipe temperature is, for example, 65°C.

[0087] The second second adjustment scenario: If the pipe temperature of the condenser is greater than the second set pipe temperature and less than or equal to the first set pipe temperature, control the compressor to operate at a preset medium-high frequency, control the operating gear of the evaporation fan not to exceed the set medium gear, and control the condensation fan to operate at a preset maximum rotational speed. Wherein, the second set pipe temperature is, for example, 60°C.

[0088] The third second adjustment scenario: If the pipe temperature of the condenser is less than or equal to the second set pipe temperature, control the compressor to operate at a preset medium-high frequency, control the operating gear of the evaporation fan not to exceed the set medium-high gear, and control the condensation fan to operate at a preset maximum rotational speed. Wherein, the second set pipe temperature is, for example, 60°C.

[0089] Specifically, as Figure 8 shown, a control method for adaptive adjustment of a portable air conditioner proposed by the solution of the present invention further includes: In step 4, the execution method of this adaptive adjustment control strategy is as follows:

[0090] Step 42: When 1°C < T 蒸发器出风温度 - T 设定运行温度 < 5°C, then perform the following judgment:

[0091] If T 冷凝器管温 > 65°C, the system considers that the pipe temperature of the condenser is too high. At this time, the central control module executes the adaptive adjustment instruction 4. When the central control module executes the adaptive adjustment instruction 4, in this state, the central control module sends an instruction to the actuator module: (1) The actuator module controls the compressor to preferentially execute the medium-high frequency operation instruction. (2) The actuator module controls the evaporator fan gear not to exceed the medium-low gear operation (that is, if the evaporator fan gear is at the high gear, medium-high gear or medium gear at this time, it is preferentially adjusted to execute the medium-low gear. If the evaporator fan gear is at the medium-low gear or low gear at this time, it maintains the original set gear operation). (3) The actuator module controls the condenser fan to preferentially operate at the maximum rotational speed.

[0092] If 60°C < T 冷凝器管温≤65 °C, the system considers that the heat exchange effect of the condenser is not good. At this time, the central control module executes the adaptive adjustment instruction 5. When the central control module executes the adaptive adjustment instruction 5, in this state, the central control module sends an instruction to the actuator module: (1) The actuator module controls the compressor to preferentially execute the medium and high frequency operation instruction. (2) The actuator module controls the evaporator fan speed not to exceed the medium speed (that is, if the evaporator fan speed is at the high speed or medium-high speed at this time, it is preferentially adjusted to the medium speed. If the evaporator fan speed is at the medium speed, medium-low speed or low speed at this time, it remains at the original set speed). (3) The actuator module controls the condenser fan to preferentially operate at the maximum speed.

[0093] If T 冷凝器管温 ≤60 °C, the system considers that there is still some heat exchange capacity in the condenser. At this time, the central control module executes the adaptive adjustment instruction 6. When the central control module executes the adaptive adjustment instruction 6, in this state, the central control module sends an instruction to the actuator module: (1) The actuator module controls the compressor to preferentially execute the medium and high frequency operation instruction. (2) The actuator module controls the evaporator fan speed not to exceed the medium-high speed (that is, if the evaporator fan speed is at the high speed at this time, it is preferentially adjusted to the medium-high speed. If the evaporator fan speed is at the medium-high speed, medium speed, medium-low speed or low speed at this time, it remains at the original set speed). (3) The actuator module controls the condenser fan to preferentially operate at the maximum speed.

[0094] Step S240, if the air outlet temperature difference of the mobile air conditioner is greater than or equal to the third set temperature difference and less than or equal to the second set temperature difference, then a third adjustment is made to the operating frequency of the compressor, the operating speed of the evaporator fan, and the operating speed or the rotational speed of the condenser fan. Among them, the third set temperature difference is, for example, -1 °C.

[0095] In some embodiments, in step S240, the third adjustment to the operating frequency of the compressor, the operating speed of the evaporator fan, and the operating speed or the rotational speed of the condenser fan includes: controlling the compressor to maintain the current frequency operation, controlling the operating speed of the evaporator fan to maintain the current speed, and controlling the condenser fan to maintain the current speed.

[0096] Specifically, as Figure 8 shown, a control method for adaptive adjustment of a portable air conditioner proposed by the solution of the present invention further includes: in step 4, the execution method of this adaptive adjustment control strategy is as follows: Step 43, when -1 °C ≤ T 蒸发器出风温度 -T 设定运行温度When the temperature difference is ≤ 1°C, the system then considers that the parameters have reached stability, and at this time, the central control module executes the adaptive adjustment instruction 7. When the central control module executes the adaptive adjustment instruction 7, in this state, the central control module sends instructions to the actuator module: (1) The actuator module controls the compressor to operate at the original frequency. (2) The actuator module controls the evaporator fan to operate at the original set wind speed. (3) The actuator module controls the condenser fan to operate at the original set wind speed.

[0097] Step S250: If the air outlet temperature difference of the mobile air conditioner is less than the third set temperature difference, then perform a fourth adjustment on the operating frequency of the compressor, the operating wind speed of the evaporator fan, and the operating wind speed of the condenser fan or the rotational speed of the condenser fan.

[0098] In some embodiments, performing the fourth adjustment on the operating frequency of the compressor, the operating wind speed of the evaporator fan, and the operating wind speed of the condenser fan or the rotational speed of the condenser fan in step S250 includes: controlling the compressor to operate at a preset medium frequency, controlling the operating wind speed of the evaporator fan not to exceed the set medium wind speed, and controlling the condenser fan to operate at a preset medium-low rotational speed.

[0099] Specifically, as Figure 8 shown, a control method for adaptive adjustment of a portable air conditioner proposed by the solution of the present invention further includes: in step 4, the execution method of this adaptive adjustment control strategy is as follows: Step 44: When T 蒸发器出风温度 - T 设定运行温度 < -1°C, the system then considers that the refrigeration capacity is excessive, and at this time, the central control module executes the adaptive adjustment instruction 8. When the central control module executes the adaptive adjustment instruction 8, in this state, the central control module sends instructions to the actuator module: (1) The actuator module controls the compressor to preferentially execute the medium-frequency operation instruction. (2) The actuator module controls the evaporator fan to operate at a wind speed not exceeding the medium wind speed (that is, if the evaporator fan is at a high wind speed or medium-high wind speed at this time, it is preferentially adjusted to the medium-high wind speed. If the evaporator fan is at a medium wind speed, medium-low wind speed, or low wind speed at this time, it maintains the original set wind speed). (3) The actuator module controls the condenser fan to preferentially operate at a medium-low rotational speed.

[0100] In some embodiments, in the solution of the present invention, in the control method of the mobile air conditioner, after adjusting the operating frequency of the compressor, the operating speed of the evaporator fan, and the operating speed of the condenser fan or the rotational speed of the condenser fan according to the outlet air temperature of the evaporator, the target temperature of the mobile air conditioner, and the pipe temperature of the condenser, or according to the outlet air temperature of the evaporator and the target temperature of the mobile air conditioner in step S130, it further includes: a process of cyclically controlling the operating frequency of the compressor, the operating speed of the evaporator fan, and the operating speed of the condenser fan or the rotational speed of the condenser fan.

[0101] The following combines Figure 3 FIG. is a schematic flowchart of an embodiment of cyclically controlling the operating frequency of the compressor, the operating speed of the evaporator fan, and the operating speed of the condenser fan or the rotational speed of the condenser fan in the method of the present invention shown, further illustrating the specific process of cyclically controlling the operating frequency of the compressor, the operating speed of the evaporator fan, and the operating speed of the condenser fan or the rotational speed of the condenser fan, including: steps S310 to S340.

[0102] Step S310, after a first set time after adjusting the operating frequency of the compressor, the operating speed of the evaporator fan, and the operating speed of the condenser fan or the rotational speed of the condenser fan, when the mobile air conditioner runs for a second set time again, a set of operating parameters of the mobile air conditioner is obtained again, and the second set time is less than the first set time. Among them, a set of operating parameters of the mobile air conditioner includes: the target temperature of the mobile air conditioner, the operating speed of the evaporator fan, the temperature at the outlet of the evaporator, that is, the outlet air temperature of the evaporator, and the operating power of the compressor.

[0103] Step S320, based on the set of operating parameters of the mobile air conditioner obtained again, determine the pipe temperature of the condenser according to the target temperature of the mobile air conditioner, the operating speed of the evaporator fan, the outlet air temperature of the evaporator, and the operating power of the compressor.

[0104] Step S330, based on the set of operating parameters of the mobile air conditioner obtained again, adjust the operating frequency of the compressor, the operating speed of the evaporator fan, and the operating speed of the condenser fan or the rotational speed of the condenser fan according to the outlet air temperature of the evaporator, the target temperature of the mobile air conditioner, and the pipe temperature of the condenser, or according to the outlet air temperature of the evaporator and the target temperature of the mobile air conditioner.

[0105] Step S340, thus, cycle according to the second set time.

[0106] As Figure 8 shown, a control method for adaptive adjustment of a portable air conditioner proposed by the solution of the present invention further includes:

[0107] Step 5: After receiving the adaptive adjustment instruction fed back by the evaporator return air temperature prediction module, the central control module sends an instruction to the actuator module to mobilize the actuator module to execute the corresponding adaptive adjustment mechanism.

[0108] Step 6: When the air conditioner operation time reaches the first set time △t1 and completes an adaptive adjustment mechanism, the timing module will execute the second timing instruction. The second timing instruction of the timing module is specifically that when the air conditioner operation time reaches the first set time △t1, the timing module will time at intervals of the second set time △t2, and subsequently, whenever the air conditioner operation time interval reaches the second set time △t2, it will start timing again at intervals of the second set time △t2. According to the laboratory measured data, the value range of the second set time △t2 is 0 to 5 minutes. In the solution of the present invention, the preferred value of the second set time △T2 is 1 minute.

[0109] Particularly, when the air conditioner operation time reaches the first set time △t1, whenever the timing module completes timing at intervals of the second set time △t2, the timing module will feedback a data acquisition instruction to the central control module. After receiving this instruction, the central control module sends an instruction to the data acquisition module. At this time, the data acquisition module will re-acquire the set operation temperature parameter, operation wind gear parameter, evaporator outlet air temperature parameter, and compressor operation power parameter of the air conditioner at this moment, and feedback the relevant information to the central control module. The central control module then calls the condenser tube temperature prediction module to execute a condenser tube temperature calculation once.

[0110] In the solution of the present invention, the following technical descriptions are made for the compressor speed, evaporator fan wind gear, and condenser fan speed in the actuator module: the operating speed range of the compressor is 20 Hz to 90 Hz, the low-frequency speed range of the compressor is 20 Hz to 35 Hz, the medium-low frequency speed range of the compressor is 35 Hz to 55 Hz, the medium-high frequency speed range of the compressor is 55 Hz to 75 Hz, and the high-frequency speed range of the compressor is 75 Hz to 90 Hz. The adjustment range of the evaporator fan wind gear is wind gear 1, wind gear 2, wind gear 3, and wind gear 4. The value range of the condenser fan speed is 800 rpm to 1800 rpm, the maximum speed range of the condenser fan is 1500 rpm to 1700 rpm, the medium-high speed range of the condenser fan is 1300 rpm to 1500 rpm, and the medium speed range of the condenser fan is 1050 rpm to 1250 rpm.

[0111] In the solution of the present invention, the preferred low-frequency rotation speed of the compressor is 20 Hz, the preferred medium-low frequency rotation speed of the compressor is 45 Hz, the preferred medium-high frequency rotation speed of the compressor is 65 Hz, and the preferred high-frequency rotation speed of the compressor is 85 Hz. The preferred low wind speed of the evaporator fan is wind speed 1, the preferred medium-low wind speed of the evaporator fan is wind speed 2, the preferred medium-high wind speed of the evaporator fan is wind speed 3, and the preferred high wind speed of the evaporator fan is wind speed 4.

[0112] The information acquisition module collects the set operating temperature, operating wind speed information, evaporator outlet air temperature information, and operating power information during the operation of the air conditioner. After being processed by the central control model and the timing module, it is sent to the condenser pipe temperature prediction module, and the condenser pipe temperature prediction module completes the data calculation and generates the calculation result of the condenser pipe temperature. The central control module will retrieve the set operating temperature parameter T 设定运行温度 and the evaporator outlet air temperature T 蒸发器出风温度 fed back by the data acquisition module, as well as the condenser pipe temperature T 冷凝器管温 fed back by the condenser pipe temperature prediction module. According to the comparison results of the set operating temperature parameter T 设定运行温度 , the evaporator outlet air temperature T 蒸发器出风温度 , and the condenser pipe temperature T 冷凝器管温 fed back by the condenser pipe temperature prediction module, the adaptive adjustment control strategy is executed.

[0113] The solution of the present invention can predict the return air temperature of the air conditioner by using the system parameters of the portable air conditioner, solving the technical problems of low utilization rate of the system parameters and low intelligence of the portable air conditioner system. To a certain extent, it can achieve the adaptive adjustment of the portable air conditioner, solving the technical problem of the adaptive control of the portable air conditioner. It improves the intelligence level of the portable air conditioner, optimizes the control strategy of the portable air conditioner, reduces the operating energy consumption, and solves the technical problem of the coordinated operation of the actuator components of the portable air conditioner system. By using the existing sensors of the portable air conditioner, no additional sensors are required, and the manufacturing cost will not increase.

[0114] Adopting the technical solution of this embodiment, after the mobile air conditioner is turned on and runs for the first set time, a set of operating parameters of the mobile air conditioner is obtained. This set of operating parameters includes the target temperature of the mobile air conditioner (such as the set operating temperature parameter), the operating wind speed of the blower at the evaporator in the mobile air conditioner (such as the operating wind speed parameter), the outlet air temperature of the evaporator in the mobile air conditioner (such as the evaporator outlet air temperature parameter), and the operating power of the compressor in the mobile air conditioner (such as the compressor operating power parameter). According to this set of operating parameters, the condenser pipe temperature of the mobile air conditioner is calculated. In different temperature ranges of the temperature difference between the outlet air temperature of the evaporator and the target temperature of the mobile air conditioner in this set of operating parameters, according to different temperature ranges of the condenser pipe temperature of the mobile air conditioner, at least one of the compressor frequency, the operating gear of the blower at the evaporator, and the operating gear or speed of the blower at the condenser is adjusted accordingly, completing an adaptive adjustment mechanism for the mobile air conditioner. After that, after the mobile air conditioner runs for the first set time again, at intervals of the second set time, a set of operating parameters of the mobile air conditioner is collected once, and an adaptive adjustment mechanism for the mobile air conditioner is completed according to this set of operating parameters, and so on in a cycle to achieve the adaptive adjustment of the mobile air conditioner. Thus, by predicting the return air temperature of the air conditioner evaporator and combining the control with the return air temperature of the air conditioner evaporator, it is beneficial to achieve stable temperature control accuracy during the use of the portable air conditioner.

[0115] According to an embodiment of the present invention, there is also provided a control device for a mobile air conditioner corresponding to the control method of the mobile air conditioner.

It can be seen that the result comparison between the condenser tube temperature calculated by the condenser tube temperature prediction mathematical model proposed in the solution application of the present invention and the measured condenser tube temperature is relatively consistent, which can meet the usage requirements of the portable air conditioner.

[0126] The control unit 104 is further configured to, based on a set of operating parameters of the mobile air conditioner obtained, adjust the operating frequency of the compressor, adjust the operating gear of the evaporator fan, and adjust the operating gear or the rotational speed of the condenser fan according to the outlet air temperature of the evaporator and the target temperature of the mobile air conditioner, as well as the tube temperature of the condenser, or according to the outlet air temperature of the evaporator and the target temperature of the mobile air conditioner.

[0127] Specifically, Figure 5It is a schematic structural diagram of an embodiment of a control system for adaptive adjustment of a portable air conditioner. As Figure 5 shown, a portable air conditioner adaptive control system proposed by the solution of the present invention includes: a data acquisition module, a central control module, a condenser pipe temperature prediction module, and an actuator module. Figure 6 It is a schematic logical framework diagram of an embodiment of a control system for adaptive adjustment of a portable air conditioner. In the Figure 6 portable air conditioner adaptive control system shown, the data acquisition module is a section responsible for data acquisition, storage, and transmission in the control system. In the solution of the present invention, the data collected by the data acquisition module includes but is not limited to the set operating temperature, operating wind speed, evaporator outlet air temperature, and operating power.

[0128] Among them, the set operating temperature refers to the operating temperature set after the air conditioner is turned on and operates. In the solution of the present invention, the selectable range of the set temperature of the air conditioner is 16°C to 30°C, and the temperature setting accuracy is 1°C.

[0129] The operating wind speed refers to the operating gear set by the evaporator fan of the air conditioner, usually including but not limited to wind speed 1, wind speed 2, wind speed 3, and wind speed 4, etc. In the solution of the present invention, after the system detects the set operating wind speed of the air conditioner, the data acquisition module will convert the operating wind speed into corresponding numerical information (for example, wind speed 1 is recognized as the numerical value "1", wind speed 2 is recognized as the numerical value "2", wind speed 3 is recognized as the numerical value "3", and wind speed 4 is recognized as the numerical value "4").

[0130] The evaporator outlet air temperature refers to the dry bulb temperature of the air at the evaporator outlet of the air conditioner. In the solution of the present invention, the evaporator outlet air temperature information is collected by a temperature sensor set at the evaporator outlet, and the temperature sensor sends the collected outlet air temperature information to the data acquisition module.

[0131] The operating power refers to the real-time power parameter during the operation of the air conditioner. In the solution of the present invention, after the system obtains the power parameter of the compressor module by detecting the power supply module, it sends the information of the power parameter of the compressor operation to the data acquisition module.

[0132] In the Figure 6 portable air conditioner adaptive control system shown, the central control module is the core control section of the air conditioner. In the solution of the present invention, the central control module is responsible for receiving the data information transmitted by the data acquisition module, activating the timing module, completing the recognition, processing, and transmission of the data information, then sending the processed data to the condenser pipe temperature prediction module, and finally, according to the calculation result of the condenser pipe temperature prediction module, activating the actuator module to complete the corresponding adaptive adjustment instruction.

[0133] In the solution of the present invention, the recognition and processing of data information by the central control module refer to: recognizing the set operating temperature information of the air conditioner and converting the set operating temperature information into corresponding numerical information. A condenser tube temperature prediction mathematical model proposed by the solution of the present invention is a numerical calculation model, and its calculation process is a calculation and processing process performed on numerical characters, and cannot perform calculations on other formats of characters, such as text strings, symbol strings, etc. Therefore, it is necessary to process the set operating temperature information of the air conditioner. For example, "set temperature 16°C" is recognized as the numerical "16" string, "set temperature 18°C" string is recognized as the numerical "18" string, "set temperature 20°C" string is recognized as the numerical "20" string, "set temperature 25°C" string is recognized as the numerical "25" string, and so on. The purpose and function of the conversion are to convert the "set operating temperature information" in the air conditioner system parameters into a numerical format that the condenser tube temperature prediction mathematical model can perform calculations on, so that the condenser tube temperature parameters required by the control device of the solution of the present invention can be obtained through the calculation of this model.

[0134] Recognize the operating wind speed information of the air conditioner evaporator fan and convert the operating wind speed information into corresponding numerical information. A condenser tube temperature prediction mathematical model proposed by the solution of the present invention is a numerical calculation model, and its calculation process is a calculation and processing process performed on numerical characters, and cannot perform calculations on other formats of characters, such as text strings, symbol strings, etc. Therefore, it is necessary to process the operating wind speed information of the air conditioner. For example, "wind speed 1" is recognized as the numerical "1" string, "wind speed 2" is recognized as the numerical "2" string, "wind speed 3" is recognized as the numerical "3" string, and "wind speed 4" is recognized as the numerical "4" string. The purpose and function of the conversion are to convert the "operating wind speed information" in the air conditioner system parameters into a numerical format that the condenser tube temperature prediction mathematical model can perform calculations on, so that the condenser tube temperature parameters required by the control device of the solution of the present invention can be obtained through the calculation of this model.

[0135] Identify the outlet air temperature information collected by the evaporator outlet temperature sensor, and convert the temperature information into numerical information that can be processed by the central control module. A condenser tube temperature prediction mathematical model proposed by the solution of the present invention is a numerical calculation model, and its calculation process is a calculation and processing process performed on numerical characters, and cannot perform calculations on other formats of characters, such as text strings, symbol strings, etc. Therefore, it is necessary to process the outlet air temperature information of the air conditioner. For example, identify "outlet air temperature 10°C" as the numerical "10" string, identify the string "outlet air temperature 15°C" as the numerical "15" string, identify the string "outlet air temperature 28°C" as the numerical "28" string, identify the string "outlet air temperature 30°C" as the numerical "30" string, and so on. The purpose and function of the conversion are to convert the "outlet air temperature information" in the air conditioner system parameters into a numerical format that the condenser tube temperature prediction mathematical model can perform calculations on, so that the condenser tube temperature parameters required by the control device of the solution of the present invention can be obtained through the calculation of this model.

[0136] Identify the power parameter information of the compressor module obtained by the power supply module, and convert the power information into numerical information that can be processed by the central control module. A condenser tube temperature prediction mathematical model proposed by the solution of the present invention is a numerical calculation model, and its calculation process is a calculation and processing process performed on numerical characters, and cannot perform calculations on other formats of characters, such as text strings, symbol strings, etc. Therefore, it is necessary to process the compressor operating power information obtained by the air conditioner battery module. For example, identify "compressor operating power 100W" as the numerical "100" string, identify the string "compressor operating power 150W" as the numerical "150" string, identify the string "compressor operating power 280W" as the numerical "280" string, identify the string "compressor operating power 300W" as the numerical "300" string, and so on. The purpose and function of the conversion are to convert the "compressor operating power information" in the air conditioner system parameters into a numerical format that the condenser tube temperature prediction mathematical model can perform calculations on, so that the condenser tube temperature parameters required by the control device of the solution of the present invention can be obtained through the calculation of this model.

[0137] In Figure 6 In a portable air conditioner adaptive control system as shown, the condenser tube temperature prediction module receives the information of the data acquisition module processed by the central control module and the timing module, calculates the air conditioner condenser tube temperature through the condenser tube temperature prediction model, and feeds back the calculation result to the central control module. The central control module determines whether to execute the adaptive adjustment instruction according to the feedback result.

[0138] In Figure 6In a portable air conditioner adaptive control system shown, the actuator module refers to an actuator capable of completing adaptive control adjustment. In the solution of the present invention, the actuator module refers to a compressor, a condenser fan, and an evaporator fan.

[0139] The solution of the present invention proposes a portable air conditioner adaptive control device, which does not require additional sensors and can be completed only by using the system parameters of the portable air conditioner. By corresponding control strategies, it is possible to predict the return air temperature of the air conditioner evaporator (i.e., the condenser tube temperature), which can reflect the average temperature of the air conditioner environment to a certain extent and is beneficial to achieving stable temperature control accuracy during the use of the portable air conditioner.

[0140] In some embodiments, the control unit 104, based on a set of operating parameters of the mobile air conditioner obtained, according to the outlet air temperature of the evaporator, the target temperature of the mobile air conditioner, and the tube temperature of the condenser, or according to the outlet air temperature of the evaporator and the target temperature of the mobile air conditioner, adjusts the operating frequency of the compressor, adjusts the operating air volume of the evaporator fan, and adjusts the operating air volume of the condenser fan or the rotational speed of the condenser fan. For the specific process, refer to the following exemplary description.

[0141] Specifically, Figure 8 It is a schematic diagram of the control logic of the adaptive control strategy for an embodiment of a device for adaptive adjustment of a portable air conditioner. As Figure 8 shown, the solution of the present invention proposes a control device for adaptive adjustment of a portable air conditioner, which is specifically a series of control strategies and execution actions jointly completed by a data acquisition module, a central control module, a timing module, a condenser tube temperature prediction module, and an actuator module. As Figure 8 shown, the solution of the present invention proposes a control device for adaptive adjustment of a portable air conditioner, including:

[0142] Step 1: First, after the air conditioner is turned on and running, the data acquisition module collects the set operating temperature, operating air volume information, evaporator outlet air temperature information, and compressor operating power information of the air conditioner. Here, the first data information judgment is completed: If the data acquisition module identifies that the compressor operating parameters of the air conditioner are completed for identification and judgment, the judgment device here is to identify the compressor operating power through the data acquisition module. For example, when the compressor operating power P 运行功率 ≤10, it is considered that the compressor has not started. Then, the central control module starts to execute the adaptive control program. However, according to experimental data, in the initial stage of the air conditioner starting and running, system parameters such as the compressor operating power and outlet air temperature of the air conditioner are in a fluctuating state, and it is not suitable for adaptive control in this stage.

[0143] Therefore, in the solution of the present invention, after the central control module starts to execute the adaptive control program, it first calls the timing module. The timing module starts timing after the central control module recognizes that the air conditioner starts to run. When the running time of the air conditioner reaches the first set time Δt1, the data acquisition module acquires the first set of set running temperature parameters, running wind speed parameters, evaporator outlet air temperature parameters, and compressor running power parameters, and sends this set of parameters to the central control module. According to the measured data in the laboratory, the value range of the first set time Δt1 is 5 - 30 min. In the solution of the present invention, the preferred value of the first set time Δt1 is 15 min.

[0144] Step 2: After the central control module receives the first set of set running temperature parameters, running wind speed parameters, evaporator outlet air temperature parameters, and compressor running power parameters acquired by the data acquisition module, according to the data processing device, it converts the set running temperature parameters, running wind speed parameters, evaporator outlet air temperature parameters, and compressor running power parameters into numerical information that the central control module can process, and then sends the numerical information of the relevant running parameters to the condenser tube temperature prediction module.

[0145] Step 3: The condenser tube temperature prediction module imports the numerical information of the relevant parameters sent by the central control module into the condenser tube temperature prediction mathematical model. The condenser tube temperature prediction mathematical model calculates the condenser tube temperature T of the air conditioner at this moment 冷凝器管温 , and feeds back the calculation result to the central control module.

[0146] Step 4: The central control module retrieves the set running temperature parameter T 设定运行温度 , the evaporator outlet air temperature T 蒸发器出风温度 fed back by the data acquisition module, and the condenser tube temperature T 冷凝器管温 fed back by the condenser tube temperature prediction module, and executes the adaptive adjustment control strategy according to the comparison result of the set running temperature parameter T 设定运行温度 , the evaporator outlet air temperature T 蒸发器出风温度 , and the condenser tube temperature T 冷凝器管温 fed back by the condenser tube temperature prediction module.

[0147] In some embodiments, the control unit 104, based on a set of operating parameters of the portable air conditioner obtained, according to the outlet air temperature of the evaporator and the target temperature of the portable air conditioner, and the tube temperature of the condenser, or according to the outlet air temperature of the evaporator and the target temperature of the portable air conditioner, adjusts the operating frequency of the compressor, adjusts the operating wind speed of the evaporator fan, and adjusts the operating wind speed or the rotational speed of the condenser fan, including:

[0148] The control unit 104 is further specifically configured to determine the temperature difference between the air outlet temperature of the evaporator and the target temperature of the mobile air conditioner, which is denoted as the air outlet temperature difference of the mobile air conditioner. For the specific functions and processes of this control unit 104, refer to step S210.

[0149] The control unit 104 is further specifically configured that if the air outlet temperature difference of the mobile air conditioner is greater than or equal to the first set temperature difference, then according to the pipe temperature of the condenser, perform a first adjustment on the operating frequency of the compressor, the operating air volume level of the evaporator fan, and the operating air volume level of the condenser fan or the rotational speed of the condenser fan. The first set temperature difference is, for example, 5°C. For the specific functions and processes of this control unit 104, refer to step S220.

[0150] In some embodiments, the control unit 104 performs a first adjustment on the operating frequency of the compressor, the operating air volume level of the evaporator fan, and the operating air volume level of the condenser fan or the rotational speed of the condenser fan according to the pipe temperature of the condenser, including any of the following first adjustment situations:

[0151] The first first adjustment situation: The control unit 104 is further specifically configured that if the pipe temperature of the condenser is greater than the first set pipe temperature, then control the compressor to operate at the preset highest frequency, control the operating air volume level of the evaporator fan not to exceed the set medium - low air volume level, and control the condenser fan to operate at the preset maximum rotational speed. The first set pipe temperature is, for example, 65°C.

[0152] The second first adjustment situation: The control unit 104 is further specifically configured that if the pipe temperature of the condenser is greater than the second set pipe temperature and less than or equal to the first set pipe temperature, then control the compressor to operate at the preset highest frequency, control the operating air volume level of the evaporator fan not to exceed the set medium air volume level, and control the condenser fan to operate at the preset maximum rotational speed. The second set pipe temperature is, for example, 60°C.

[0153] The third first adjustment situation: The control unit 104 is further specifically configured that if the pipe temperature of the condenser is less than or equal to the second set pipe temperature, then control the compressor to operate at the preset highest frequency, control the operating air volume level of the evaporator fan not to exceed the set medium - high air volume level, and control the condenser fan to operate at the preset maximum rotational speed. The second set pipe temperature is, for example, 60°C.

[0154] Specifically, as Figure 8 shown, a control device for adaptive adjustment of a portable air conditioner proposed by the solution of the present invention further includes: In step 4, the execution device of this adaptive adjustment control strategy is as follows:

[0155] Step 41. When T 蒸发器出风温度 -T设定运行温度 When the temperature is ≥5℃, the following judgments are executed:

[0156] If T 冷凝器管温 >65℃, the system considers that the condenser tube temperature is too high. At this time, the central control module executes the adaptive adjustment instruction 1. When the central control module executes the adaptive adjustment instruction 1, in this state, the central control module sends an instruction to the actuator module: (1) The actuator module controls the compressor to preferentially execute the high-frequency operation instruction. (2) The actuator module controls the evaporator fan speed not to exceed the medium-low speed (that is, if the evaporator fan speed is high speed, medium-high speed or medium speed at this time, it is preferentially adjusted to medium-low speed. If the evaporator fan speed is medium-low speed or low speed at this time, it maintains the original set speed). (3) The actuator module controls the condenser fan to preferentially operate at the maximum speed.

[0157] If 60℃<T 冷凝器管温 ≤65℃, the system considers that the heat exchange effect of the condenser is not good. At this time, the central control module executes the adaptive adjustment instruction 2. When the central control module executes the adaptive adjustment instruction 2, in this state, the central control module sends an instruction to the actuator module: (1) The actuator module controls the compressor to preferentially execute the high-frequency operation instruction. (2) The actuator module controls the evaporator fan speed not to exceed the medium speed (that is, if the evaporator fan speed is high speed or medium-high speed at this time, it is preferentially adjusted to medium speed. If the evaporator fan speed is medium speed, medium-low speed or low speed at this time, it maintains the original set speed). (3) The actuator module controls the condenser fan to preferentially operate at the maximum speed.

[0158] If T 冷凝器管温 ≤60℃, the system considers that there is still some margin in the heat exchange capacity of the condenser. At this time, the central control module executes the adaptive adjustment instruction 3. When the central control module executes the adaptive adjustment instruction 3, in this state, the central control module sends an instruction to the actuator module: (1) The actuator module controls the compressor to preferentially execute the high-frequency operation instruction. (2) The actuator module controls the evaporator fan speed not to exceed the medium-high speed (that is, if the evaporator fan speed is high speed at this time, it is preferentially adjusted to medium-high speed. If the evaporator fan speed is medium-high speed, medium speed, medium-low speed or low speed at this time, it maintains the original set speed). (3) The actuator module controls the condenser fan to preferentially operate at the maximum speed.

[0159] The control unit 104 is further specifically configured to, if the air outlet temperature difference of the mobile air conditioner is greater than the second set temperature difference and less than the first set temperature difference, perform a second adjustment on the operating frequency of the compressor, the operating air volume level of the evaporator fan, and the operating air volume level of the condenser fan or the rotational speed of the condenser fan according to the pipe temperature of the condenser. The second set temperature difference is, for example, 1°C. For the specific functions and processes of this control unit 104, refer to step S230

[0160] In some embodiments, the control unit 104 performs a second adjustment on the operating frequency of the compressor, the operating air volume level of the evaporator fan, and the operating air volume level of the condenser fan or the rotational speed of the condenser fan according to the pipe temperature of the condenser, including any of the following second adjustment scenarios:

[0161] The first second adjustment scenario: The control unit 104 is further specifically configured to, if the pipe temperature of the condenser is greater than the first set pipe temperature, control the compressor to operate at a preset medium-high frequency, control the operating air volume level of the evaporator fan not to exceed the set medium-low air volume level, and control the condenser fan to operate at a preset maximum rotational speed. The first set pipe temperature is, for example, 65°C.

[0162] The second second adjustment scenario: The control unit 104 is further specifically configured to, if the pipe temperature of the condenser is greater than the second set pipe temperature and less than or equal to the first set pipe temperature, control the compressor to operate at a preset medium-high frequency, control the operating air volume level of the evaporator fan not to exceed the set medium air volume level, and control the condenser fan to operate at a preset maximum rotational speed. The second set pipe temperature is, for example, 60°C.

[0163] The third second adjustment scenario: The control unit 104 is further specifically configured to, if the pipe temperature of the condenser is less than or equal to the second set pipe temperature, control the compressor to operate at a preset medium-high frequency, control the operating air volume level of the evaporator fan not to exceed the set medium-high air volume level, and control the condenser fan to operate at a preset maximum rotational speed. The second set pipe temperature is, for example, 60°C.

[0164] Specifically, as Figure 8 shown, a control device for adaptive adjustment of a portable air conditioner proposed by the solution of the present invention further includes: In step 4, the execution device of this adaptive adjustment control strategy is as follows:

[0165] Step 42. When 1°C < T 蒸发器出风温度 -T 设定运行温度 < 5°C, then perform the following judgment:

[0166] If T 冷凝器管温> 65°C, the system considers that the condenser tube temperature is too high, and at this time the central control module executes the adaptive adjustment instruction 4. When the central control module executes the adaptive adjustment instruction 4, in this state, the central control module sends an instruction to the actuator module: (1) The actuator module controls the compressor to preferentially execute the medium and high frequency operation instruction. (2) The actuator module controls the evaporator fan speed not to exceed the medium and low speed (that is, if the evaporator fan speed is high speed, medium and high speed or medium speed at this time, it is preferentially adjusted to execute medium and low speed. If the evaporator fan speed is medium and low speed or low speed at this time, it maintains the original set speed). (3) The actuator module controls the condenser fan to preferentially operate at the maximum speed.

[0167] If 60°C < T 冷凝器管温 ≤ 65°C, the system considers that the heat exchange effect of the condenser is not good, and at this time the central control module executes the adaptive adjustment instruction 5. When the central control module executes the adaptive adjustment instruction 5, in this state, the central control module sends an instruction to the actuator module: (1) The actuator module controls the compressor to preferentially execute the medium and high frequency operation instruction. (2) The actuator module controls the evaporator fan speed not to exceed the medium speed (that is, if the evaporator fan speed is high speed or medium and high speed at this time, it is preferentially adjusted to execute medium speed. If the evaporator fan speed is medium speed, medium and low speed or low speed at this time, it maintains the original set speed).

After being processed by the central control model and the timing module, it is sent to the condenser tube temperature prediction module, and the condenser tube temperature prediction module completes the data calculation and generates the calculation result of the condenser tube temperature. The central control module will retrieve the set operating temperature parameter T 设定运行温度 , the evaporator outlet air temperature T 蒸发器出风温度 , and the condenser tube temperature T 冷凝器管温 fed back by the condenser tube temperature prediction module, and execute the adaptive adjustment control strategy according to the comparison result of the set operating temperature parameter T 设定运行温度 , the evaporator outlet air temperature T 蒸发器出风温度 , and the condenser tube temperature T 冷凝器管温 fed back by the condenser tube temperature prediction module.
