Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to an air conditioning system, a self-cleaning control method, a device, a vehicle, and related equipment. Background Technology

[0002] To remove bacteria and odors from automotive air conditioning systems, these systems offer a self-cleaning function. The self-cleaning mechanism of automotive air conditioning systems can be similar to that of household air conditioners. However, automotive air conditioning systems have two heat exchangers located inside the vehicle: an evaporator for cooling and a condenser for heating, which makes the self-cleaning effect of household air conditioners less effective. Summary of the Invention

[0003] This application provides an air conditioning system, a self-cleaning control method, an apparatus, a vehicle, and related equipment, which improves the self-cleaning effect of the air conditioning system and at least partially solves the above-mentioned technical problems.

[0004] According to a first aspect of this application, an air conditioning system is provided for use in a vehicle, comprising:

[0005] The evaporator and condenser are located in the passenger compartment of the vehicle;

[0006] The first valve, located in the evaporator, is used to regulate the refrigerant flow through the evaporator;

[0007] The second valve, located on the condenser, is used to regulate the refrigerant flow through the condenser.

[0008] According to a second aspect of this application, a self-cleaning control method is provided, the method being applied to any of the air conditioning systems described above, comprising:

[0009] The valve openings of the first and second valves in the air conditioning system are controlled to allow one of the evaporator and condenser to self-clean first, followed by the other.

[0010] According to a third aspect of this application, a control device is provided, including a processor, a memory, and a computer program or instructions, wherein the computer program or instructions are stored in the memory and executed by the processor to implement any of the self-cleaning control methods.

[0011] According to a fourth aspect of this application, a computer-readable storage medium is provided having a computer program or instructions stored thereon, the computer program or instructions being executed by a processor to implement any of the self-cleaning control methods.

[0012] According to a fifth aspect of this application, a computer program product is provided, comprising a computer program or instructions, which are executed by a processor to implement any of the self-cleaning control methods.

[0013] According to a sixth aspect of this application, a vehicle is provided, including any one of the control devices or any one of the air conditioning systems.

[0014] In summary, the vehicle in this application embodiment includes an air conditioning system, which includes a control device, a computer-readable storage medium, and a computer program product for performing steps in the self-cleaning control method. This allows for the regulation of refrigerant flow through the evaporator using a first valve disposed on the evaporator, and the regulation of refrigerant flow through the condenser using a second valve disposed on the condenser. This provides the possibility for alternating cleaning of the evaporator and condenser, thereby improving the self-cleaning effect of the air conditioning system through alternating cleaning.

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0026] In related technologies, the overall control logic of the self-cleaning function of a household air conditioning system is: condensation-frost-defrost-drying. However, household air conditioning systems are fundamentally different from automotive air conditioning systems. The indoor unit of a household air conditioning system basically only has a heat exchanger that can be used for both cooling and heating, while an automotive air conditioning system has an evaporator for cooling and a condenser for heating. Therefore, a special self-cleaning logic function needs to be developed for automotive air conditioning systems.

[0027] Therefore, embodiments of this application provide an air conditioning system, a self-cleaning control method, an apparatus, a vehicle, and related equipment. The vehicle includes an air conditioning system, and the air conditioning system includes a control device. The control device, a computer-readable storage medium, and a computer program product are used to execute the steps in the self-cleaning control method. This allows for the regulation of refrigerant flow through the evaporator using a first valve located on the evaporator, and the regulation of refrigerant flow through the condenser using a second valve located on the condenser. This provides the possibility for alternating cleaning of the evaporator and condenser, thereby improving the self-cleaning effect of the air conditioning system through alternating cleaning, better removing bacteria and odors from the air conditioning system, and increasing efficiency.

[0028] Specifically, this application provides an air conditioning system applied to a vehicle. (Refer to...) Figure 1 The air conditioning system includes an evaporator 6 and a condenser 5, both located within the vehicle's passenger compartment to provide cooling and heating functions. The passenger compartment is as follows: Figure 1 As shown in the dashed box.

[0029] The air conditioning system also includes a first valve 8 and a second valve 7. The first valve 8 is located on the evaporator 6, for example, at the refrigerant inlet of the evaporator 6, and is used to regulate the refrigerant flow through the evaporator 6. The second valve 7 is located on the condenser 5, for example, at the refrigerant inlet of the condenser 5, and is used to regulate the refrigerant flow through the condenser 5. By controlling the opening degree of the first valve 8 and the second valve 7, the refrigerant flow through the evaporator 6 and the condenser 5 can be regulated, providing the possibility for alternating cleaning of the evaporator 6 and the condenser 5, thereby improving the self-cleaning effect of the air conditioning system through alternating cleaning.

[0030] In some embodiments, the first valve 8 and the second valve 7 may be, for example, electronic expansion valves to achieve precise regulation of refrigerant flow.

[0031] In some embodiments, the evaporator 6 is connected to the condenser 5 via a second valve 7, that is, the evaporator 6 and the condenser 5 are connected in series. For example, the refrigerant can first pass through the evaporator 6, and then flow through the second valve 7 to the condenser 5, thereby realizing the cooling function of the evaporator 6 and the heating function of the condenser 5 in the passenger compartment.

[0032] In some embodiments, the air conditioning system further includes a first heat exchanger 14, which is located outside the passenger compartment and is connected to the evaporator 6 via a first valve 8. The heat exchanger 14 is used to transfer heat from inside the passenger compartment to outside the passenger compartment by means of the flow of refrigerant between the first heat exchanger 14 and the evaporator 6, thereby realizing the cooling function of the evaporator 6 inside the passenger compartment.

[0033] In some embodiments, the air conditioning system further includes a four-way valve 3, a compressor 1, and a gas-liquid separator 2. The air conditioning system includes a first cleaning mode and a second cleaning mode. In the first cleaning mode, the four-way valve 3 connects the compressor 1 to the first heat exchanger 14, and to the condenser 5 and the gas-liquid separator 2. Thus, the refrigerant output from the compressor 1 passes sequentially through the first heat exchanger 14, the evaporator 6, the condenser 5, and the gas-liquid separator 2, achieving the cooling function of the evaporator 6. In the second cleaning mode, the four-way valve 3 connects the compressor 1 to the condenser 5, and to the first heat exchanger 14 and the gas-liquid separator 2. Thus, the refrigerant output from the compressor 1 passes sequentially through the condenser 5, the evaporator 6, the first heat exchanger 14, and the gas-liquid separator 2, achieving the heating function of the condenser 5. It can be seen that by switching the cleaning mode of the air conditioning system, the cooling function of the evaporator 6 and the heating function of the condenser 5 can be achieved, thereby simplifying the structure of the air conditioning system and reducing its cost.

[0034] In some embodiments, the compressor 1 is connected to the gas-liquid separator 2. In this way, combined with the four-way valve 3, a refrigerant circulation loop can be formed to achieve continuous cooling or continuous heating of the air conditioning system.

[0035] In some embodiments, the air conditioning system further includes a first fan 15, and a first heat exchanger 14 is disposed on the air outlet side or air inlet side of the first fan 15. Alternatively, the first fan 15 may also be disposed outside the passenger compartment. Operation of the first fan 15 can accelerate airflow near the first heat exchanger 14, thereby improving the heat exchange efficiency of the first heat exchanger 14.

[0036] In some embodiments, the air conditioning system further includes a second heat exchanger 10, and the first heat exchanger 14 is also connected to the condenser 5 through the second heat exchanger 10. The second heat exchanger 10 is used to exchange heat with the target battery 12 in the vehicle. For example, the cooling function of the second heat exchanger 10 can be used to cool the target battery 12 to prevent the target battery 12 from becoming too hot. The second heat exchanger 10 may be, for example, a plate heat exchanger.

[0037] In some embodiments, the air conditioning system further includes a third valve 11, through which the first heat exchanger 14 is connected to the second heat exchanger 10. It can be seen that the third valve 11 can be used to regulate the refrigerant flow rate through the second heat exchanger 10, thereby adjusting the heat exchange capacity of the second heat exchanger 10 so that its heat exchange capacity matches the heat exchange requirements of the target battery 12. Furthermore, the third valve 11 can be, for example, an electronic expansion valve to achieve precise regulation of the refrigerant flow rate.

[0038] In some embodiments, the air conditioning system further includes a fourth valve 9, through which the second heat exchanger 10 is connected to the condenser 5. Since refrigerant can flow from the condenser 5 to the second heat exchanger 10 when the four-way valve 3 connects the compressor 1 and the condenser 5, causing the second heat exchanger 10 to heat the target battery 12, the closure of the fourth valve 9 can prevent refrigerant from flowing from the condenser 5 to the second heat exchanger 10, thus avoiding heating of the target battery 12 during self-cleaning. Furthermore, the fourth valve 9 can be, for example, a shut-off valve to control the on / off flow of the refrigerant line.

[0039] In some embodiments, the air conditioning system further includes a target liquid cooling circuit, in which the second heat exchanger 10 and the target battery 12 are both disposed. The second heat exchanger 10 is used to exchange heat with the target liquid cooling circuit, thereby utilizing the target liquid cooling circuit to exchange heat with the target battery 12. The target liquid cooling circuit may be, for example, a water cooling circuit.

[0040] In some embodiments, the air conditioning system further includes a target pump 13 disposed in a target liquid cooling circuit for driving the liquid cooling medium in the target liquid cooling circuit to circulate, thereby circulating heat exchange between the second heat exchanger 10 and the target battery 12. The target pump 13 may be, for example, a water pump.

[0041] In some embodiments, the air conditioning system further includes a second fan 16, with a condenser 5 and / or an evaporator 6 disposed in the air outlet path of the second fan 16, thereby utilizing the condenser 5 and / or the evaporator 6 to allow the second fan 16 to blow hot air and / or cold air. The second fan 16 may be, for example, a blower.

[0042] In some embodiments, a second fan 16 is also provided in the passenger compartment to blow hot and / or cold air into the passenger compartment.

[0043] In some embodiments, the air conditioning system further includes a control device connected to a first valve 8 and a second valve 7, for controlling the valve opening of the first valve 8 and the second valve 7, thereby adjusting the refrigerant flow through the evaporator 6 and the condenser 5, providing the possibility for alternating cleaning of the evaporator 6 and the condenser 5, and thereby improving the self-cleaning effect of the air conditioning system through alternating cleaning.

[0044] In some embodiments, the air conditioning system further includes a fifth valve 4, through which the condenser 5 is connected to the four-way valve 3. The fifth valve 4 is used for refrigerant flow control when the air conditioning system is not self-cleaning, for example, for refrigerant flow control when the air conditioning system is in cooling mode and / or heating mode.

[0045] According to a second aspect of this application, a self-cleaning control method is provided, which is applied to any of the air conditioning systems described above, specifically to the control device within the air conditioning system. This self-cleaning control method possesses all the beneficial effects of the aforementioned air conditioning systems, which will not be elaborated upon here. Please refer to... Figure 2 The self-cleaning control method provided in this application includes step 100, which will be described in detail below.

[0046] Step 100: Control the valve opening of the first valve and the second valve in the air conditioning system to perform self-cleaning on one of the evaporator and condenser of the air conditioning system first, and then on the other.

[0047] In this embodiment, one of the evaporator and condenser in the air conditioning system is self-cleaned first, and the other is self-cleaned later. This can be done by cleaning the evaporator first and then the condenser, or vice versa; no limitation is made here. By performing self-cleaning on one of the evaporator and condenser first and then the other, the evaporator and condenser can be cleaned separately with focused attention, thereby improving the self-cleaning effect of the air conditioning system.

[0048] In some embodiments, step 100 may include: controlling the opening degree of the first valve to be less than the opening degree of the second valve to perform self-cleaning of the evaporator; and controlling the opening degree of the second valve to be less than the opening degree of the first valve to perform self-cleaning of the condenser. When the opening degree of the first valve is less than the opening degree of the second valve, the refrigerant flow rate into the evaporator is smaller, and the refrigerant entering the evaporator undergoes a greater degree of gas-liquid phase transformation, thereby improving the cooling and / or heating effect of the evaporator and achieving focused cleaning of the evaporator. Similarly, when the opening degree of the second valve is less than the opening degree of the first valve, the refrigerant flow rate into the condenser is smaller, and the refrigerant entering the condenser undergoes a greater degree of gas-liquid phase transformation, thereby improving the cooling and / or heating effect of the condenser and achieving focused cleaning of the condenser.

[0049] In some embodiments, controlling the valve opening of the first valve to be less than the valve opening of the second valve may include: adjusting the valve opening of the second valve to a preset maximum opening and controlling the valve opening of the first valve to be less than the preset maximum opening, thereby further increasing the difference in refrigerant flow between the condenser and the evaporator, and further strengthening the key cleaning of the evaporator.

[0050] In some embodiments, controlling the valve opening of the second valve to be less than the valve opening of the first valve may include: adjusting the valve opening of the first valve to a preset maximum opening and controlling the valve opening of the second valve to be less than the preset maximum opening, thereby further increasing the difference in refrigerant flow between the evaporator and the condenser, and further strengthening the key cleaning of the condenser.

[0051] In some embodiments, self-cleaning of the evaporator may include: controlling the evaporator to cool, so that the evaporator undergoes condensation and frosting processes sequentially; and controlling the evaporator to heat, so that the evaporator undergoes defrosting and drying processes sequentially. It can be seen that this embodiment utilizes the evaporator's condensation-frost-defrosting-drying logic to achieve self-cleaning of the evaporator.

[0052] In some embodiments, during the self-cleaning process of the evaporator, the air conditioning system may meet at least one of the following conditions:

[0053] When the evaporator is frosting, the valve opening of the first valve is smaller than that when the evaporator is condensing, so as to reduce the evaporation temperature when the evaporator is frosting, which is beneficial to the frosting of the evaporator.

[0054] When the evaporator is frosting, the speed of the second fan in the air conditioning system is lower than that when the evaporator is condensing, so as to reduce the air velocity near the evaporator during the frosting process, which is beneficial to the frosting of the evaporator.

[0055] When the evaporator is frosting, the operating frequency of the compressor in the air conditioning system is greater than that when the evaporator is condensing, in order to improve the cooling capacity of the evaporator during the frosting process and facilitate the frosting of the evaporator.

[0056] When the evaporator is frosting, the speed of the first fan in the air conditioning system is greater than the speed of the first fan when the evaporator is condensing, so as to improve the cooling capacity of the evaporator during the frosting process and facilitate the frosting of the evaporator.

[0057] When the evaporator is drying, the valve opening of the first valve is smaller than that when the evaporator is defrosting, so as to increase the condensation temperature of the evaporator during the drying process, which is beneficial to the drying of the evaporator.

[0058] The speed of the second fan during the drying process of the evaporator is greater than that during the defrosting process of the evaporator, so as to increase the air velocity near the evaporator during the drying process, which is beneficial to the drying of the evaporator.

[0059] The compressor operates at a higher frequency during the drying process than during the defrosting process, in order to improve the heating capacity of the evaporator during the drying process and facilitate the drying of the evaporator.

[0060] The speed of the first fan during the drying process of the evaporator is greater than that during the defrosting process of the evaporator, so as to improve the heating capacity of the evaporator during the drying process and facilitate the drying of the evaporator.

[0061] In some embodiments, during the self-cleaning process of the evaporator, the air conditioning system may also meet at least one of the following conditions:

[0062] When the evaporator is defrosting, the valve opening of the first valve is greater than that when the evaporator is condensing, so that the evaporator can gradually begin to defrost.

[0063] When the evaporator is defrosting, the speed of the second fan is greater than that when the evaporator is condensing, so as to increase the air velocity near the evaporator during defrosting, which is beneficial to defrosting and dust removal of the evaporator.

[0064] The compressor operates at a higher frequency during defrosting than during condensation, in order to improve the heating capacity of the evaporator during defrosting and facilitate defrosting.

[0065] When the evaporator is defrosting, the speed of the first fan is greater than that when the evaporator is condensing, in order to improve the heating capacity of the evaporator during defrosting and facilitate defrosting.

[0066] In some embodiments, it is detected whether the evaporator is sufficiently frosted. Specifically, the self-cleaning control method further includes: when the evaporator is frosting, acquiring a first evaporation temperature of the evaporator; if the first evaporation temperature meets a first preset condition, determining that the evaporator is sufficiently frosted, and thus executing the step of controlling the evaporator to heat, so that the evaporator sequentially performs defrosting and drying processes.

[0067] In some embodiments, the first preset condition may include: a first evaporation temperature less than or equal to a first evaporation threshold, and the duration of the first evaporation temperature being less than or equal to the first evaporation threshold being greater than a first preset duration. Wherein, the first evaporation temperature being less than or equal to the first evaporation threshold indicates that the evaporator will frost at the first evaporation temperature, and the duration of the first evaporation temperature being less than or equal to the first evaporation threshold being greater than the first preset duration indicates that the evaporator is sufficiently frosted.

[0068] In some embodiments, the complete drying of the evaporator is detected. Specifically, the self-cleaning control method further includes: during the drying process of the evaporator, obtaining a first condensing temperature of the evaporator; if the first condensing temperature meets a second preset condition, determining that the evaporator is completely dried, and thus executing a step of controlling the valve opening of the first valve to be greater than the valve opening of the second valve to perform self-cleaning of the condenser.

[0069] In some embodiments, the second preset condition may include: a first condensing temperature greater than or equal to a first condensing threshold, and the duration for which the first condensing temperature is greater than or equal to the first condensing threshold is greater than a second preset duration. Wherein, a first condensing temperature greater than or equal to the first condensing threshold indicates that moisture on the evaporator will evaporate at the first condensing temperature, and the duration for which the first condensing temperature is greater than or equal to the first condensing threshold is greater than the second preset duration indicates that moisture on the evaporator has been completely evaporated.

[0070] In some embodiments, the evaporator is detected to ensure sufficient condensation. Specifically, the self-cleaning control method may further include: when the evaporator is undergoing condensation treatment, acquiring the duration of the condensation treatment; if the duration of the condensation treatment is longer than a third preset duration, it indicates that the evaporator is sufficiently condensed, and therefore the evaporator can be controlled to perform frosting treatment.

[0071] In some embodiments, the complete defrosting of the evaporator is detected. Specifically, the self-cleaning control method may further include: during the defrosting process of the evaporator, acquiring the duration of the defrosting process; if the duration of the defrosting process of the evaporator is greater than a fourth preset duration, it indicates that the evaporator is completely defrosted, and therefore the evaporator can be controlled to perform a drying process.

[0072] In some embodiments, self-cleaning of the condenser may include: controlling the condenser to cool, so that the condenser undergoes condensation and frosting processes sequentially; and controlling the condenser to heat, so that the condenser undergoes defrosting and drying processes sequentially. It can be seen that this embodiment utilizes the condenser's condensation-frost-defrosting-drying logic to achieve self-cleaning of the condenser.

[0073] In some embodiments, during the self-cleaning process of the condenser, the air conditioning system may meet at least one of the following conditions:

[0074] When the condenser is frosting, the valve opening of the second valve is smaller than that when the condenser is condensing, so as to reduce the evaporation temperature of the condenser during frosting and facilitate the frosting of the condenser.

[0075] When the condenser is frosting, the speed of the second fan in the air conditioning system is lower than that when the condenser is condensing, so as to reduce the air velocity near the condenser during the frosting process, which is beneficial to the frosting of the condenser.

[0076] When the condenser is frosting, the operating frequency of the compressor in the air conditioning system is greater than that when the condenser is condensing, in order to improve the cooling capacity of the condenser during the frosting process and facilitate the frosting of the condenser.

[0077] When the condenser is frosting, the speed of the first fan in the air conditioning system is greater than the speed of the first fan when the condenser is condensing, so as to improve the cooling capacity of the condenser during the frosting process and facilitate the frosting of the condenser.

[0078] When the condenser is being dried, the valve opening of the second valve is smaller than that when the condenser is being defrosted, so as to increase the condensing temperature when the condenser is being dried, which is beneficial to the drying of the condenser.

[0079] The speed of the second fan during the drying process of the condenser is greater than the speed of the second fan during the defrosting process of the condenser, so as to increase the air velocity near the condenser during the drying process, which is beneficial to the drying of the condenser.

[0080] The compressor operates at a higher frequency during the drying process than during the defrosting process, in order to improve the heating capacity of the condenser during the drying process and to facilitate the drying of the condenser.

[0081] The speed of the first fan during the drying process of the condenser is greater than that during the defrosting process of the condenser, so as to improve the heating capacity of the condenser during the drying process and facilitate the drying of the condenser.

[0082] In some embodiments, during the self-cleaning process of the condenser, the air conditioning system may also meet at least one of the following conditions:

[0083] When the condenser is defrosting, the valve opening of the second valve is greater than that when the condenser is condensing, so that the condenser can gradually begin to defrost.

[0084] When the condenser is defrosting, the speed of the second fan is greater than that when the condenser is condensing, in order to increase the air velocity near the condenser during defrosting, which is beneficial for defrosting and dust removal.

[0085] The compressor operates at a higher frequency during defrosting than during condensation, in order to improve the heating capacity of the condenser during defrosting and facilitate defrosting.

[0086] When the condenser is defrosting, the speed of the first fan is greater than that when the condenser is condensing, in order to improve the heating capacity of the condenser during defrosting and facilitate defrosting.

[0087] In some embodiments, the condenser is sufficiently frosted. Specifically, the self-cleaning control method further includes: when the condenser is frosting, acquiring a second evaporation temperature of the condenser; if the second evaporation temperature meets a third preset condition, determining that the condenser is sufficiently frosted, and thus executing the step of controlling the condenser to heat, so that the condenser sequentially undergoes defrosting and drying processes.

[0088] In some embodiments, the third preset condition may include: the second evaporation temperature is less than or equal to the second evaporation threshold, and the duration of the second evaporation temperature being less than or equal to the second evaporation threshold is greater than a fifth preset duration. Wherein, the second evaporation temperature being less than or equal to the second evaporation threshold indicates that the condenser will frost at the second evaporation temperature, and the duration of the second evaporation temperature being less than or equal to the second evaporation threshold being greater than the fifth preset duration indicates that the condenser is sufficiently frosted.

[0089] In some embodiments, the completeness of the condenser drying process is detected. Specifically, the self-cleaning control method further includes: acquiring a second condensation temperature of the condenser during the drying process; if the second condensation temperature meets a fourth preset condition, it is determined that the condenser is completely dry, and thus the drying process can be stopped, thereby completing the self-cleaning of the condenser.

[0090] In some embodiments, the fourth preset condition may include: a second condensation temperature greater than or equal to a second condensation threshold, and the duration for which the second condensation temperature is greater than or equal to the second condensation threshold is greater than a sixth preset duration. Wherein, a second condensation temperature greater than or equal to the second condensation threshold indicates that moisture on the condenser will evaporate at the second condensation temperature, and the duration for which the second condensation temperature is greater than or equal to the second condensation threshold is greater than the sixth preset duration indicates that moisture on the condenser has been completely evaporated.

[0091] In some embodiments, the condenser is detected to be sufficiently condensed. Specifically, the self-cleaning control method may further include: when the condenser is undergoing condensation treatment, acquiring the duration of the condensation treatment; if the duration of the condensation treatment is longer than a seventh preset duration, it indicates that the condenser is sufficiently condensed, and therefore the condenser can be controlled to undergo frosting treatment.

Specifically, the self-cleaning control method may further include: during the defrosting process of the condenser, acquiring the duration of the defrosting process; if the duration of the defrosting process of the condenser is greater than an eighth preset duration, it indicates that the condenser is completely defrosted, and therefore the condenser can be controlled to perform a drying process.

[0093] In some embodiments, the cooling and heating of the evaporator and / or condenser can be achieved by switching the cleaning mode of the air conditioning system. Specifically, the air conditioning system can be controlled in a first cleaning mode to cool the evaporator and / or condenser, and the air conditioning system can be controlled in a second cleaning mode to heat the evaporator and / or condenser.

[0094] In some embodiments, the self-cleaning function of the air conditioning system can be activated based on the triggering of a corresponding command. Specifically, the self-cleaning control method may further include: in response to an air conditioning self-cleaning command, executing a step of controlling the valve opening of a first valve and a second valve in the air conditioning system to perform self-cleaning on one of the evaporator and condenser of the air conditioning system first, followed by self-cleaning on the other. The air conditioning self-cleaning command can be triggered, for example, through the user interface of the vehicle's central control screen.

[0095] In some embodiments, the self-cleaning control method may further include: periodically outputting self-cleaning reminder information for the air conditioning system to trigger an air conditioning self-cleaning command based on the self-cleaning reminder information. In this way, by periodically reminding the user to activate the self-cleaning function of the air conditioning system, the evaporator and condenser in the air conditioning system can be kept clean.

[0096] In some embodiments, combined with Figure 1 and Figure 2The self-cleaning control method is illustrated with an example. In this example, the self-cleaning control method is divided into a first cleaning cycle and a second cleaning cycle. The first cleaning cycle is used to self-clean the evaporator 6, and the second cleaning cycle is used to self-clean the condenser 5.

[0097] The first cleaning cycle consists of two parts of logic that are executed sequentially, as follows:

[0098] (1) The air conditioning system is in the first cleaning mode. At this time, the refrigerant is compressed in the compressor 1 and then enters the first heat exchanger 14. At this time, the third valve 11 is closed. Then the refrigerant passes through the first valve 8 and enters the evaporator 6. At this time, the second valve 7 is fully open. The refrigerant continues to flow through the condenser 5 and the fifth valve 4. At this time, the fifth valve 4 is fully open. Finally, the refrigerant passes through the gas-liquid separator 2 and returns to the suction end of the compressor 1, completing the refrigerant cycle in the first part of the logic.

[0099] (2) The air conditioning system is in the second cleaning mode. At this time, the refrigerant is compressed in the compressor 1, and then enters the condenser 5 through the fifth valve 4. At this time, the fourth valve 9 is closed. The refrigerant enters the evaporator 6 through the second valve 7, which is fully open. Then, it enters the first heat exchanger 14 through the first valve 8, where the third valve 11 is closed. Finally, the refrigerant returns to the suction end of the compressor 1 through the gas-liquid separator 2, completing the refrigerant cycle in the second part of the logic.

[0100] The second cleaning cycle consists of two parts of logic that are executed sequentially, as follows:

[0101] (1) The air conditioning system is in the first cleaning mode. At this time, the refrigerant is compressed in the compressor 1 and then enters the first heat exchanger 14. At this time, the third valve 11 is closed. Then the refrigerant passes through the first valve 8 and enters the evaporator 6. At this time, the first valve 8 is fully open. The refrigerant continues to flow through the condenser 5 and the fifth valve 4. At this time, the fifth valve 4 is fully open. Finally, the refrigerant passes through the gas-liquid separator 2 and returns to the suction end of the compressor 1, completing the refrigerant cycle in the first part of the logic.

[0102] (2) The air conditioning system is in the second cleaning mode. At this time, the refrigerant is compressed in the compressor 1, and then enters the condenser 5 through the fifth valve 4. At this time, the fourth valve 9 is closed. The refrigerant enters the evaporator 6 through the second valve 7. The first valve 8 is fully open. The refrigerant enters the first heat exchanger 14 through the first valve 8. At this time, the third valve 11 is closed. Finally, the refrigerant returns to the suction end of the compressor 1 through the gas-liquid separator 2, completing the refrigerant cycle in the second part of the logic.

[0103] Reference Figure 3Taking the self-cleaning of evaporator 6 using the first cleaning cycle as an example:

[0104] The first part of the logic for entering the first cleaning cycle is as follows: The purpose of the first step is to condense water to produce condensate. The speed of the second fan 16 is within the second speed range, which is relatively low and conducive to producing more condensate water. At this time, the operating frequency of the compressor 1, the speed of the first fan 15, and the valve opening of the first valve 8 are relatively small, which also facilitates condensation. After the condensation operation time t, sufficient condensate water is produced, and the second step begins. The second step is the frosting stage. At this time, the operating frequency of the compressor 1 increases, the speed of the first fan 15 increases, and the valve opening of the first valve 8 decreases to lower the evaporation temperature of the evaporator 6 to achieve a frosting state. Subsequently, the evaporation temperature is judged, and frosting is detected based on the evaporation temperature. After running for time t1, sufficient frosting is ensured.

[0105] The second part of the first cleaning cycle logic is as follows: The first step is the initial defrosting stage. The speed of the second fan 16 is within the first speed range, which is conducive to defrosting and dust blowing; the operating frequency of compressor 1 is within the first frequency range, the speed of the first fan 15 is within the first speed range, and the valve opening of the first valve 8 is within the first opening range. After running t2, the second step begins, which is the high-temperature drying and steam washing stage. The speed of the second fan 16 is increased to accelerate the flow of hot steam, the operating frequency of compressor 1 is increased, the speed of the first fan 15 is increased, and the valve opening of the first valve 8 is decreased to increase the condensing temperature of evaporator 6. Subsequently, the condensing temperature of evaporator 6 is judged, and it is detected whether the high-temperature drying temperature has been reached. After running t3, the high-temperature drying is ensured to be completed.

[0106] Reference Figure 4 This illustrates the logic for self-cleaning of condenser 5 using the first cleaning cycle.

[0107] Among them, the first frequency range of compressor 1 is greater than the second frequency range of compressor 1. For example, the first frequency range of compressor 1 is 80 Hz-110 Hz, and the second frequency range of compressor 1 is 50-80 Hz.

[0108] The first speed range of the first fan 15 is greater than the second speed range of the first fan 15. For example, the first speed range of the first fan 15 is 2000-3000, and the second speed range of the first fan 15 is 1000-2000.

[0109] The first speed range of the second fan 16 is greater than the second speed range of the second fan 16. For example, the first speed range of the second fan 16 is 1200-2500 revolutions per minute, and the second speed range of the second fan 16 is 800-1200 revolutions per minute.

[0110] The first opening range of the first valve 8 is greater than the second opening range of the first valve 8.
