[0002] With the development of economy and technology, the application of air conditioners is becoming more and more widespread. Air conditioners use the indoor heat exchanger in the heat pump cycle to heat the air, and then send the heated air into the indoor environment through the fan to adjust the indoor air temperature.

[0003] During the heating process of the air conditioner, the air conditioner generally adjusts the air temperature through the heat pump circulation alone. Its adjustment ability is limited. When the operating conditions are poor or the user has restrictions on wind feeling and noise, the heating efficiency is prone to poor, and the indoor temperature rises too slowly, affecting the comfort of indoor users. Summary of the Invention

[0004] The present invention heats the indoor air by arranging a radiation module on the air conditioner in conjunction with the heat pump module of the air conditioner, thereby improving the heating operation of the air conditioner to meet the user's comfort.

[0053] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0054] The main solution of an embodiment of the present invention is: based on an air conditioner equipped with a device for releasing radiation waves to heat indoor air, the method obtains a characteristic temperature related to the operation of the radiation module when the air conditioner is in heating operation; determines the control parameters of the radiation temperature of the radiation module based on the characteristic temperature; and controls the operation of the radiation module and / or the heat dissipation module corresponding to the radiation module based on the control parameters.

[0055] In the prior art, during the heating process of the air conditioner, the air conditioner generally adjusts the air temperature through the heat pump circulation alone, and its adjustment ability is limited. When the operating conditions are poor or the user has restrictions on the wind feeling and noise, the problem of poor heating efficiency is likely to occur, and the indoor temperature rises too slowly, affecting the comfort of indoor users.

[0056] The present invention provides the above-mentioned solution, which aims to heat the indoor air by setting a radiation module in cooperation with the heat pump module of the air conditioner to improve the heating operation of the air conditioner to meet the user comfort. On this basis, the radiation temperature of the radiation module is regulated according to the relevant characteristic temperature during the operation of the radiation module in the heating state of the air conditioner, which can effectively improve the heating efficiency of the air conditioner while increasing the service life of the radiation module.

[0057] An embodiment of the present invention provides an air conditioner. In this embodiment, the air conditioner is a wall-mounted air conditioner. In other embodiments, the air conditioner may also be a cabinet air conditioner, a window air conditioner, a portable air conditioner, etc.

[0058] In the embodiment of the present invention, referring to Figure 1 The air conditioner includes a radiation module 1. The radiation module 1 is used to release radiation waves to heat the indoor air or replenish the heat required by the human body. In this embodiment, the radiation module 1 is an infrared radiation module 1, which heats the indoor air by releasing infrared rays.

[0059] The air conditioner may further include a housing 2 and a heat pump module 3. The heat pump module 3 includes an indoor heat exchanger 31 and an indoor fan 32 corresponding to the indoor heat exchanger 31. The housing 2 is provided with a return air port 21 and an air outlet 22. An air duct connecting the return air port 21 and the air outlet 22 is provided within the housing 2. The indoor heat exchanger 31 and the indoor fan 32 are disposed within the air duct. The indoor fan 32 drives indoor air from the return air port 21 into the air duct. Liquid carrying heat or cold can enter the indoor heat exchanger 31 to exchange heat with the indoor air in the air duct. The heat-exchanged indoor air can then be delivered into the room through the air outlet 22.

[0060] The number of the air outlets 22 can be set according to actual needs, and can be one, two or more.

[0061] The radiation module 1 can be mounted on the outer surface of the housing 2, or as part of the housing 2, or it can be mounted within the air duct. When mounted on the outer surface of the housing 2, or as part of the housing 2, the radiation waves emitted by the radiation module 1 can be directly released into the indoor environment to heat the air therein. When mounted within the air duct, the radiation module 1 can cooperate with the indoor heat exchanger 31 to heat the indoor air entering the air duct. The heated air is then delivered to the indoor environment through the air outlet 22.

[0062] Specifically, the radiation module 1 may be provided with multiple vents to allow air to flow through different locations of the radiation module 1, thereby increasing the heat dissipation area of ​​the radiation module 1 and improving the air heating efficiency of the radiation module 1. Furthermore, the vents on the radiation module 1 can be used as return air vents 21 to heat the return air; alternatively, the vents on the radiation module 1 can be used as outlet vents 22 to heat the outlet air. The radiation module 1 may also be provided with valves to open or close the multiple vents.

[0063] The air outlet 22 may be provided with an air guide member, which can be used to control the air outlet direction and / or the air volume flowing through the air outlet 22. If there are more than one air outlet 22, each air outlet 22 may be provided with an air guide member 4 to achieve independent control of the air outlet direction and / or the air volume flowing through each air outlet 22.

[0064] In one embodiment of the air conditioner, Figure 1 As shown in Figure 2 (a), radiation module 1 is located outside housing 2. Air entering the air duct from return air inlet 21 is heated by indoor heat exchanger 31 before being delivered to the indoor environment through air outlet 22. Furthermore, radiation module 1, located outside housing 2, emits radiation waves that directly heat the air near housing 2.

[0065] In another embodiment of the air conditioner, Figure 1 As shown in Figure (b), the radiation module 1 is disposed within the air duct, with the multiple vents serving as the return air vents 21 of the air conditioner. Driven by the indoor fan 32, indoor air can enter the air duct through the multiple vents of the radiation module 1. The radiation module 1 releases radiation waves to heat the air entering the air duct. The heated air then undergoes further heat exchange in the indoor heat exchanger 31, and the heated air is then delivered to the indoor environment through the air outlet 22. Furthermore, the number of air outlets 22 can be more than one, and each air outlet 22 can be independently regulated in terms of airflow direction and / or airflow volume by a corresponding air guide 4.

[0066] Furthermore, the air conditioner may also include a temperature detection module 5, which is used to detect characteristic temperatures related to the operation of the radiation module 1. The characteristic temperature here can be a temperature parameter that characterizes the heating demand of the radiation module 1, or a temperature parameter that characterizes the operational reliability of the radiation module 1, etc. In this embodiment, the temperature detection module 5 includes a first temperature sensor, a second temperature sensor, and a third temperature sensor. Specifically, the first temperature sensor is provided on the surface of the radiation module 1 to detect the temperature of the radiation module 1. The second temperature sensor is provided on the indoor heat exchanger 31 to detect the temperature of the indoor heat exchanger 31. The third temperature sensor is provided in the indoor environment or outside the housing 2 to detect the indoor ambient temperature.

[0067] Further, refer to Figure 2 The air conditioner may further include a control device, to which the radiation module 1, heat pump module 3, and temperature detection module 5 are all connected. The control device can be used to control the operation of the radiation module 1 and heat pump module 3, and can also be used to obtain temperature detection data from the temperature detection module 5.

[0068] In the embodiment of the present invention, referring to Figure 2 The control device may include: a processor 1001 (e.g., a CPU), a memory 1002, etc. The processor 1001 and the memory 1002 are connected via a communication bus. The memory 1002 may be a high-speed RAM memory or a non-volatile memory such as a disk storage device. The memory 1002 may also be a storage device independent of the processor 1001.

[0069] Those skilled in the art will understand that Figure 2 The device structure shown in the figure does not constitute a limitation of the device, and may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0070] like Figure 2 As shown, the memory 1002 as a computer readable storage medium may include a control program for the air conditioner. Figure 2 In the device shown, the processor 1001 can be used to call the air conditioner control program stored in the memory 1002 and execute the relevant steps of the air conditioner control method in the following embodiments.

[0071] An embodiment of the present invention further provides a method for controlling an air conditioner, for controlling the operation of the air conditioner.

[0072] Reference Figure 3 , an embodiment of a control method for an air conditioner of the present application is proposed. In this embodiment, the control method for an air conditioner includes:

[0073] Step S10, when the air conditioner is in a heating operation state, obtaining a characteristic temperature related to the operation of the radiation module;

[0074] During the heating operation of the air conditioner, the heat pump module is turned on, the indoor heat exchanger is in a condensing state to release heat, and the indoor heat exchanger heats the indoor air through heat exchange. During this process, the radiation module can be controlled to turn on to release heat synchronously with the indoor heat exchanger to heat the indoor air.

[0075] During the process of turning on the radiation module, characteristic temperatures related to the operation of the radiation module can be obtained. The characteristic temperature here specifically refers to a temperature characteristic parameter that characterizes the operation status or operation requirements of the radiation module. Specifically, it can be a temperature parameter that characterizes the heating demand of the radiation module (such as the indoor heat exchanger temperature and / or the indoor ambient temperature), or a temperature parameter that characterizes the operational reliability of the radiation module (such as the radiation module temperature).

[0076] Here, the number of characteristic temperatures obtained may be one or more. For example, the indoor heat exchanger temperature, the indoor ambient temperature, and the radiation module temperature may be obtained as characteristic temperatures, or a portion of the indoor heat exchanger temperature, the indoor ambient temperature, and the radiation module temperature may be selected as characteristic temperatures.

[0077] Step S20, determining a control parameter of the radiation temperature of the radiation module according to the characteristic temperature;

[0078] The control parameters herein specifically refer to target operating parameters of a temperature control component used to increase, decrease, or maintain the radiation temperature of the radiation module. The temperature control component herein may be the radiation module itself or a heat dissipation module corresponding to the radiation module. For example, the control parameters may include the radiation power of the radiation module, the number of open vents on the radiation module, the heat dissipation power (e.g., fan speed) of the heat dissipation module corresponding to the radiation module, and / or activation parameters of the radiation module.

[0079] Different characteristic temperatures correspond to different control parameters. The correspondence between characteristic temperatures and control parameters can be pre-set and can be a mapping relationship, a calculated relationship, or the like. Based on this mapping relationship, the control parameter corresponding to the current characteristic temperature can be determined. In this correspondence, in this embodiment, as the characteristic temperature increases, the target value of the radiation temperature of the radiation module corresponding to the control parameter decreases. Conversely, as the characteristic temperature decreases, the target value of the radiation temperature of the radiation module corresponding to the control parameter increases. In other embodiments, the relationship between the characteristic temperature and the radiation temperature corresponding to the control parameter may follow other patterns or may not have a clear pattern. For example, the lower the indoor heat exchanger temperature, the radiation module temperature or the indoor ambient temperature, the greater the radiation power of the radiation module may be, and the higher the indoor heat exchanger temperature, the radiation module temperature or the indoor ambient temperature, the smaller the radiation power of the radiation module may be; the lower the radiation module temperature, the lower the fan speed corresponding to the radiation module may be, and the higher the radiation module temperature, the higher the fan speed corresponding to the radiation module may be; the higher the radiation module temperature, the more open vents corresponding to the radiation module may be, and the lower the radiation module temperature, the fewer open vents corresponding to the radiation module may be; the higher the indoor heat exchanger temperature or the indoor ambient temperature, the fewer open vents corresponding to the radiation module may be, and the lower the indoor heat exchanger temperature or the indoor ambient temperature, the more open vents corresponding to the radiation module may be.

[0080] Step S30: controlling the radiation module and / or the heat dissipation module corresponding to the radiation module to operate according to the control parameters.

[0081] When the control parameters include operating parameters such as the radiation power of the radiation module, the radiation module can be controlled to operate at the radiation power, so as to adjust the radiation temperature of the radiation module by adjusting the input of the radiation module itself, for example, controlling the radiation module to use the voltage corresponding to the radiation power as the input voltage of the radiation module.

[0082] When the control parameters include the heat dissipation parameters of the heat dissipation module corresponding to the radiation module, the heat dissipation module can be controlled to operate according to the heat dissipation parameters, thereby adjusting the radiation temperature of the radiation module by adjusting the heat dissipation efficiency of the radiation module. In this embodiment, the heat dissipation module includes a fan. For example, when the radiation module is located within an air duct, the heat dissipation module is an indoor fan within the air duct. In other embodiments, the heat dissipation module can also be any other type of heat dissipation element. Specifically, the heat dissipation module can also include a heat dissipation pipeline connected to the radiation module for heat exchange, such as a pipeline for supplying cold water.

[0083] Specifically, when the control parameters include reducing the operating power of the radiation module, the radiation module can be controlled to reduce the input voltage; when the control parameters include increasing the speed of the cooling fan corresponding to the radiation module, the fan can be controlled to increase the current speed; when the control parameters include turning off the radiation module, the radiation module can be controlled to turn off, stop releasing radiation waves to stop heating the indoor air.

[0084] A control method for an air conditioner proposed in an embodiment of the present invention is based on an air conditioner provided with a radiation module for releasing radiation waves to heat indoor air. The radiation module can be turned on during the heating process of the air conditioner to increase the heating amount of the air conditioner, thereby improving the heating efficiency of the air conditioner for the indoor environment. The method controls the operation of the radiation module or the heat dissipation module corresponding to the radiation module based on the characteristic temperature related to the operation of the radiation module to achieve control of the radiation temperature of the radiation module, which can avoid the radiation temperature of the radiation module being too high or too low, effectively improving the heating efficiency of the air conditioner while increasing the service life of the radiation module.

[0085] Furthermore, based on the above embodiment, another embodiment of the control method for the air conditioner of the present application is proposed. In this embodiment, the characteristic temperature includes the radiation module temperature of the radiation module, the indoor heat exchanger temperature of the air conditioner, or the indoor ambient temperature. The heat dissipation module includes a fan. Specifically, when the radiation module is disposed in an air duct, the fan here refers to the indoor fan in the air duct. The operating parameters of the indoor fan affect the amount of heat dissipated by the radiation module. Specifically, the greater the speed of the indoor fan, the greater the heat dissipation of the radiation module, and the smaller the speed of the indoor fan, the smaller the heat dissipation of the radiation module.

[0086] In one case, when the characteristic temperature includes the radiation module temperature, step S20 includes:

[0087] Step S21, when the temperature of the radiation module is greater than or equal to a first preset temperature, determining the control parameters includes reducing the operating power of the radiation module, increasing the speed of the fan, and shutting down the radiation module; wherein, when the fan speed increases, the heat dissipation of the radiation module increases.

[0088] The temperature of the radiation module is specifically obtained by acquiring temperature data detected by a temperature sensor disposed on the surface of the radiation module.

[0089] The first preset temperature corresponding to the radiation module temperature is the critical value of the radiation module surface temperature used to determine whether the radiation module is operating safely. This first preset temperature can be a fixed temperature configured by the system default, or a temperature selected from multiple preset temperatures based on the maximum speed allowed for the fan and / or the current indoor ambient temperature.

[0090] The power adjustment parameter when reducing power or the speed adjustment parameter when increasing fan speed may be a preset fixed parameter, or a parameter determined based on the temperature difference between the radiation module temperature and the first preset temperature.

[0091] If the radiation module temperature is greater than or equal to the first preset temperature, it indicates that the current operation of the radiation module poses a safety risk. In this case, the radiation module's radiation temperature can be lowered by reducing operating power or shutting down the radiation module to reduce the radiated heat output. Alternatively, the fan speed can be increased to increase the heat dissipation of the radiation module. This prevents damage to the radiation module due to excessive temperature, thereby ensuring reliable operation and extending the service life of the radiation module. If the radiation module temperature is less than the first preset temperature, it indicates that the radiation module is currently in a safe operating state. In this case, the radiation module or its corresponding heat dissipation module can maintain its current state of operation or be controlled based on other parameters without restriction, such as increasing the radiation power of the radiation module or reducing the fan speed.

[0092] Further, step S21 may include: when the temperature of the radiation module is greater than or equal to the first preset temperature, and the temperature of the radiation module is less than the second preset temperature, determining the control parameter to reduce the operating power of the radiation module and / or increase the speed of the fan; when the temperature of the radiation module is greater than or equal to the second preset temperature, determining the control parameter to shut down the radiation module; wherein, the second preset temperature is greater than the first preset temperature.

[0093] The second preset temperature is specifically a critical value of the surface temperature of the radiation module for distinguishing high and low safety risks of the radiation module operation.

[0094] Among them, when the temperature of the radiation module is greater than or equal to the first preset temperature and the temperature of the radiation module is lower than the second preset temperature, the installation position of the radiation module can be obtained. When the installation position of the radiation module is outside the air duct, the control parameter can be determined to reduce the operating power of the radiation module; when the installation position of the radiation module is inside the air duct, the control parameter can be determined to increase the speed of the fan.

[0095] Specifically, when the radiation module temperature is greater than or equal to the second preset temperature, it indicates that the radiation module is operating at a high risk. Shutting down the radiation module at this time ensures that the radiation module temperature is rapidly reduced, ensuring that the radiation module's operation does not cause safety accidents, thereby extending the radiation module's service life while improving the safety of the air conditioner. When the radiation module temperature is greater than or equal to the first preset temperature but lower than the second preset temperature, it indicates that the radiation module's operating safety risk is low. Increasing the fan speed or reducing the radiation module's power at this time will help maintain the heat output of the radiation module to the indoor environment, ensuring improved heating efficiency and extending the radiation module's service life.

[0096] In another case, when the characteristic temperature includes the indoor heat exchanger temperature, step S20 includes:

[0097] Step S22: When the temperature of the indoor heat exchanger is greater than or equal to a third preset temperature, determining the control parameter includes reducing the operating power of the radiation module or shutting down the radiation module.

[0098] The indoor heat exchanger temperature is specifically obtained by acquiring temperature data detected by a temperature sensor provided on the indoor heat exchanger coil.

[0099] The third preset temperature corresponding to the indoor heat exchanger temperature is a critical value used to determine whether the heat output of the indoor heat exchanger (represented by the change in indoor ambient temperature per unit time) is sufficient. This third preset temperature can be a fixed temperature configured by the system by default, or a temperature selected from multiple preset temperatures based on the current operating speed of the indoor fan and / or the temperature difference between the current outlet air temperature and the target outlet air temperature.

[0100] The power adjustment parameter when reducing the power may be a preset fixed parameter, or may be a parameter determined based on the temperature difference between the indoor heat exchanger temperature and the third preset temperature.

[0101] If the indoor heat exchanger temperature is greater than or equal to the third preset temperature, it indicates that the indoor heat exchanger outputs sufficient heat. In this case, the radiant temperature of the radiant module can be lowered by reducing operating power or shutting down the radiant module to reduce its radiant heat output. This can ensure the air conditioner's heating efficiency while saving energy consumption. In particular, when the radiant module is located within the air duct, reducing the radiant heat output of the radiant module helps improve the heat exchange efficiency of the heat pump module and ensure reliable operation of the air conditioner's heat pump circulation system, thereby improving the air conditioner's energy efficiency. It can also prevent the radiant module from overheating and being damaged by the heat output of the indoor heat exchanger, thereby extending the service life of the radiant module. If the indoor heat exchanger temperature is less than the third preset temperature, it indicates that the indoor heat exchanger outputs insufficient heat. In this case, the radiant module can maintain its current operating state or increase its output power, thereby effectively improving the air conditioner's heating efficiency.

[0102] Further, step S22 includes: when the temperature of the indoor heat exchanger is greater than or equal to a third preset temperature and the indoor heat exchanger is less than a fourth preset temperature, determining that the control parameter is to reduce the operating power of the radiation module; when the temperature of the indoor heat exchanger is greater than or equal to the fourth preset temperature, determining that the control parameter is to turn off the radiation module; wherein the fourth preset temperature is greater than the third preset temperature.

[0103] The fourth preset temperature is specifically a temperature critical value of the indoor heat exchanger used to distinguish whether a heat pump circulation system in which the indoor heat exchanger is located has a reliability risk.

[0104] Here, the power adjustment parameters in the process of reducing the operating power can be determined according to the exhaust temperature of the compressor of the heat pump module where the indoor heat exchanger is located. Different exhaust temperatures correspond to different power adjustment parameters. The radiation module can be controlled to reduce the operating power according to the determined power adjustment parameters.

[0105] Specifically, when the temperature of the indoor heat exchanger is greater than or equal to the fourth preset temperature, the heat pump circulation system in which the indoor heat exchanger resides is reliable. At this time, shutting down the radiation module can rapidly reduce the radiation temperature of the radiation module, ensuring that the system pressure of the heat pump circulation system does not become excessively high, ensuring the reliable operation of the heat pump circulation system, and ensuring its stable heat output to the indoor air. When the temperature of the indoor heat exchanger reaches above the third preset temperature but below the fourth preset temperature, it indicates that the heat output of the indoor heat exchanger is sufficient and the heat pump system in which it resides is operating reliably. Reducing the operating power of the radiation module in this case can help save energy consumption, avoid reliability issues with the heat pump system, and ensure that the heat pump system in which the indoor heat exchanger resides can exchange heat for the indoor air with high energy efficiency.

[0106] In another case, when the characteristic temperature includes the indoor ambient temperature, step S20 includes:

[0107] Step S23: When the indoor ambient temperature is greater than or equal to a fifth preset temperature, determining the control parameter includes reducing the operating power of the radiation module or shutting down the radiation module.

[0108] The indoor environment temperature can be specifically obtained by acquiring temperature data detected by a temperature sensor installed in the indoor environment.

[0109] The fifth preset temperature corresponding to the indoor ambient temperature is specifically the temperature threshold used to determine whether the indoor environment will cause the user to experience a cold indoor environment. This fifth preset temperature can be a fixed temperature configured by the system by default, or a temperature selected from multiple preset temperatures based on the current fan speed, the current temperature of the indoor heat exchanger, and / or the current temperature of the radiation module.

[0110] The power adjustment parameter when reducing the power may be a preset fixed parameter, or may be a parameter determined based on the temperature difference between the indoor ambient temperature and the fifth preset temperature.

[0111] If the indoor ambient temperature is greater than or equal to the fifth preset temperature, the current indoor ambient temperature is high enough to not make the user feel cold. In this case, the radiant module's temperature is lowered by reducing operating power or shutting down the module, thereby reducing its radiant heat output and effectively saving the air conditioner's energy consumption. If the indoor ambient temperature is less than the fifth preset temperature, the current indoor ambient temperature is low enough to make the user feel cold. In this case, the radiant module remains on or its operating power is increased to ensure effective heating efficiency, allowing the indoor environment to quickly reach a comfortable temperature for the user.

[0112] Further, in this embodiment, step S23 includes: when the indoor ambient temperature is greater than or equal to the fifth preset temperature, obtaining the target state of the heating operation of the air conditioner; the target state includes the target heating amount or the target operating noise required to be achieved when the air conditioner is heating operation; when the target state is a state other than the first state and the second state, executing the step of determining the control parameters including reducing the operating power of the radiation module or turning off the radiation module; wherein, the first state is that the target heating amount is greater than the set heating amount or the current heating amount of the air conditioner, and the second state is that the target operating noise is less than the set noise threshold or the current operating noise of the air conditioner.

[0113] The target state can be determined by obtaining a command input by the user, or by monitoring the scene within the current air conditioner's operating space. For example, when there is a first command input by the user indicating that heating priority is present, the target state can be determined to be the first state (i.e., the target heating amount is greater than the set heating amount or the current heating amount of the air conditioner). When there is a second command input by the user indicating that silent priority is present, the target state can be determined to be the second state (i.e., the target operating noise is less than the set noise threshold or the current operating noise of the air conditioner). If there is no first command or second command input by the user, the target state can be determined to be a state other than the first state and the second state. Alternatively, the number of occurrences of the heating command within the current time and set duration is obtained. If the number of occurrences is greater than or equal to the set number, the target state can be determined to be the first state (i.e., the target heating amount is greater than the set heating amount or the current heating amount of the air conditioner). If the current time period is within a preset rest period (such as a nighttime sleep period or a midday sleep period), the target state can be determined to be the second state (i.e., the target operating noise is less than the set noise threshold). If the number of occurrences is less than the set number and the current time period is outside the preset rest period, the target state can be determined to be a state other than the first state and the second state. When the target state is other than the first state and the second state, it indicates that there is no demand for large heating capacity or low noise, and there is no need to use the radiation module and the heat pump module to work together to make the air conditioner achieve the effect of large heating capacity or low noise. At this time, reducing the operating power of the radiation module or even turning off the radiation module can ensure that the heating operation of the air conditioner meets the actual comfort needs of the user while reducing the energy consumption of the air conditioner.

[0114] Furthermore, after the step of obtaining the target state of the heating operation of the air conditioner, it also includes: when the target state is the first state, controlling the heat pump module of the air conditioner to maintain the heating operation and controlling the radiation module to maintain the on state; when the target state is the second state, controlling the heat pump module to stop the heating operation and controlling the radiation module to maintain the on state. In the first state, the heat pump module and the radiation module of the air conditioner are used for synchronous heating, which is beneficial for the two modules to cooperate so that the air conditioner can output a large amount of heat, achieve rapid heating of the indoor environment, and ensure that the indoor environment can quickly reach the user's comfortable temperature. In the second state, the heat pump module of the air conditioner is turned off (the compressor and / or indoor fan are turned off), while the radiation module is kept on to release radiation waves to heat the indoor air, which is beneficial for reducing the operating noise of the compressor, fan, etc. of the heat pump module while maintaining the required heat for the indoor environment through the radiation module, ensuring the thermal comfort of the users in the indoor environment.

[0115] In this embodiment, during the operation of the air conditioner, one of the above three temperatures can be pre-configured as the default characteristic temperature, or one of the above three temperatures can be selected as the characteristic temperature based on the actual operation of the air conditioner combined with preset rules, or all three temperatures can be used as characteristic temperatures.

[0116] Specifically, when the characteristic temperature is one of the three temperatures described above, one of steps S21, S22, and S23 may be selected to determine the control parameters for the radiation temperature of the radiation module. When the characteristic parameter is more than one of the three temperatures described above, step S20 may include at least two of steps S21, S22, and S23. When any one of the temperatures reaches the corresponding condition, the operation of the radiation module and / or the heat dissipation module corresponding to the radiation module is controlled according to the corresponding control parameters.

[0117] It should be noted that, in other embodiments, the characteristic temperature may be a temperature other than the above three temperatures, such as the outdoor ambient temperature, the air outlet temperature, etc.

[0118] Furthermore, based on any of the above embodiments, another embodiment of the control method of the air conditioner of the present application is proposed. In this embodiment, referring to Figure 4 , the step S10 includes:

[0119] Step S11, obtaining the radiation module temperature of the radiation module, the indoor heat exchanger temperature of the air conditioner, the indoor ambient temperature, and the duration of the heating operation of the air conditioner;

[0120] The specific method for obtaining the radiation module temperature, the indoor heat exchanger temperature and the indoor ambient temperature can be found in the above embodiment and will not be described in detail here.

[0121] The duration here can be specifically started when the air conditioner starts heating. While the air conditioner maintains heating, the timed duration can be used as the duration here. It should be noted that when the air conditioner starts heating, the heat pump module can be controlled to heat and the radiation module can be controlled to turn on, so that the two modules can heat synchronously.

[0122] Step S12: determining one of the radiation module temperature, the indoor heat exchanger temperature, and the indoor ambient temperature as the characteristic temperature according to the duration.

[0123] Among the radiation module temperature, indoor ambient temperature, and indoor heat exchanger temperature, different durations correspond to different characteristic temperatures.

[0124] Specifically, in this embodiment, when the duration is less than the first preset duration, the radiation module temperature is determined to be the characteristic temperature; when the duration is greater than or equal to the first preset duration and the duration is less than the second preset duration, the indoor heat exchanger temperature is determined to be the characteristic temperature; when the duration is greater than or equal to the second preset duration, the indoor ambient temperature is determined to be the characteristic temperature; wherein, the second preset duration is greater than the first preset duration.

[0125] The first preset duration and the second preset duration here may be preset duration parameters.

[0126] In this embodiment, based on the different heating times of the air conditioner, different temperatures are selected from the indoor ambient temperature, indoor heat exchanger temperature and radiation module temperature as characteristic temperatures, so as to achieve precise control of the temperature of the radiation module during the heating process, so as to ensure that the radiation module improves the heating efficiency of the air conditioner while extending its service life and saving energy consumption.

[0127] Among them, at the beginning of heating, the temperature of the indoor heat exchanger is generally low, while the heat demand of the radiation module is large. At this time, the radiation temperature of the radiation module is controlled based on the radiation module temperature, which can ensure that the heat radiated by the radiation module meets the heating efficiency of the air conditioner while extending the service life of the radiation module; and when the heating continues for a certain period of time, the temperature of the indoor heat exchanger is high enough. At this time, the radiation temperature of the radiation module is regulated based on the indoor heat exchanger temperature, which can ensure the heating efficiency of the air conditioner while reducing the energy consumption of the radiation module and improving the heating energy efficiency of the heat pump module; when the heating operation time is long enough, the radiation temperature of the radiation module is regulated based on the indoor ambient temperature, thereby ensuring the heating efficiency of the air conditioner while reducing the energy consumption of the radiation module.

[0128] In other embodiments, the above three temperatures and a preset formula may be combined to calculate a characteristic temperature, and the control parameters of the radiation temperature of the radiation module may be determined based on the calculated characteristic temperature.

[0129] Furthermore, based on any of the above embodiments, another embodiment of the control method of the air conditioner of the present application is proposed. In this embodiment, the heat dissipation module corresponding to the radiation module includes a fan, referring to Figure 5 , while executing step S30, further comprising:

[0130] Step S40, when there is a shutdown instruction for the air conditioner, if the radiation module is in the on state or the current temperature of the radiation module is greater than or equal to the set temperature threshold, the radiation module is controlled to be turned off, and the fan is controlled to remain on for a preset time.

[0131] The shutdown command is specifically used to power off the air conditioner. When the shutdown command is issued, indicating that the air conditioner is no longer needed for heating, the heat pump module's compressor is shut down, and the current operating status or surface temperature of the radiation module is obtained. If the radiation module is on or indicates that the temperature is too high, the fan is delayed for a preset period of time to dissipate heat from the radiation module, ensuring safe operation of the air conditioner while extending the module's service life.

[0132] In addition, an embodiment of the present invention further proposes a computer-readable storage medium, on which a control program for an air conditioner is stored. When the control program for the air conditioner is executed by a processor, the relevant steps of any embodiment of the above air conditioner control method are implemented.
