[0002] With the development of economy and technology, the application of air conditioners is becoming more and more widespread. Air conditioners use an indoor heat exchanger in a heat pump cycle to exchange heat with the air, and then send the heat-exchanged air into the indoor environment through a fan to regulate the indoor air temperature.

[0003] During the heating process of an air conditioner, the air conditioner generally regulates the air solely through the heat pump circulation. Its regulation capability is limited.

[0055] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0056] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0057] The main solution of this invention is: based on an air conditioner equipped with a radiation module, the operating mode of the air conditioner is obtained; when the operating mode is heating mode, the radiation module is controlled to turn on, and when the radiation module is turned on, the air on the air inlet side of the indoor heat exchanger is heated.

[0058] In the current technology, during the heating process of an air conditioner, the air conditioner generally regulates the air solely through a heat pump circulation. Its regulation capability is limited. When the operating conditions are poor or the user has restrictions on the wind feel and noise, the heating efficiency is prone to be poor, the indoor temperature rises too slowly, and the comfort of the indoor users is affected.

[0059] The present invention provides the above-mentioned solution, which aims to improve the heating efficiency of air conditioners, thereby improving the comfort of indoor users when the air conditioner is in heating mode.

[0060] This 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 floor-standing air conditioner, a window air conditioner, a portable air conditioner, etc.

[0061] In this embodiment of the invention, reference is made to Figure 1 The air conditioner includes a radiation module 1. The radiation module 1 is used to release radiation waves to heat indoor air. In this embodiment, the radiation module 1 is an infrared radiation module 1, which heats indoor air by releasing infrared rays.

[0062] The air conditioner may also 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 inlet 21 and an air outlet 22. The housing 2 is provided with an air duct connecting the return air inlet 21 and the air outlet 22. The indoor heat exchanger 31 and the indoor fan 32 are located in the air duct. The indoor fan 32 can drive indoor air to enter the air duct from the return air inlet 21. 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 be sent into the room through the air outlet 22.

[0063] The number of air outlets 22 can be set according to actual needs, and can be one, two or more.

[0064] The radiant module 1 can be installed at the return air vent of the air conditioner. When the radiant module is turned on, the indoor air enters the air duct and is first heated by the radiant module 1. Then, it is further heated by the indoor heat exchanger. The heated air is then sent into the environment from the air outlet.

[0065] Specifically, the radiant module 1 can be equipped with multiple ventilation openings to allow air to flow through different locations within the module, increasing its heat dissipation area and improving its heating efficiency. Specifically, the ventilation openings on the radiant module 1 can serve as return air inlets 21 to heat the return air. The radiant module 1 can also be equipped with valves to open or close the aforementioned ventilation openings.

[0066] The air outlet 22 may be equipped with an air guide, which can be used to regulate the air outlet direction and / or the air volume passing through the air outlet 22. When there is more than one air outlet 22, each air outlet 22 may be equipped with an air guide 4 to achieve independent regulation of the air outlet direction and / or the air volume passing through each air outlet 22.

[0067] In this embodiment, there are two air outlets 22. The radiant module 1 is located inside the air duct, and the multiple vents on the radiant module 1 can serve as 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 radiant module 1. The radiant module 1 can release radiation waves to heat the air entering the air duct. The heated air can be further heated by the indoor heat exchanger 31, and the heated air is then sent into the indoor environment through the air outlets 22.

[0068] In one embodiment of the heat pump module 3, the heat pump module 3 may be a refrigerant circulation system, which includes a compressor, an indoor heat exchanger 31, a throttling device, and an outdoor heat exchanger connected in sequence by pipelines. The pipelines of the refrigerant circulation system are filled with a refrigerant such as fluoride (e.g., Freon). When the compressor is turned on, the refrigerant circulates between the compressor, the indoor heat exchanger 31, the throttling device, and the outdoor heat exchanger. The refrigerant flowing through the indoor heat exchanger 31 can exchange heat with the air in the duct to regulate the temperature of the air in the duct.

[0069] Furthermore, the refrigerant circulation system may also include a four-way valve to enable the air conditioner to switch between cooling and heating modes. Specifically, the compressor's discharge port, compressor return port, one end of the indoor heat exchanger 31, and one end of the outdoor heat exchanger are connected to the four ports of the four-way valve. The four-way valve has different valve positions, each corresponding to a different heat exchange mode of the air conditioner. When the four-way valve is in the first position, the air conditioner is in heating mode. The refrigerant from the compressor discharge port passes sequentially through the indoor heat exchanger 31, the throttling device, and the outdoor heat exchanger before returning to the compressor from the compressor's return port. The indoor heat exchanger 31 is in a condensing state, exchanging heat with the air in the duct to raise the air temperature. When the four-way valve is in the second position, the air conditioner is in cooling mode. The refrigerant from the compressor discharge port passes sequentially through the outdoor heat exchanger, the throttling device, and the indoor heat exchanger 31 before returning to the compressor from the compressor's return port. The indoor heat exchanger 31 is in an evaporating state, exchanging heat with the air in the duct to lower the air temperature.

[0070] In another embodiment of the heat pump module 3, the heat pump module 3 may include a refrigerant circulation system and a water circulation system. The water circulation system includes the aforementioned indoor heat exchanger 31 and an outdoor heat exchanger, with the outdoor heat exchanger located in the outdoor environment. The refrigerant circulation system is heat-exchange connected to the outdoor heat exchanger. The pipes in the water circulation system are filled with liquid water, while the pipes in the refrigerant circulation system are filled with a refrigerant such as a fluoride (e.g., Freon). During the refrigerant circulation system, the refrigerant circulates and exchanges heat with the water in the outdoor heat exchanger to regulate the temperature of the circulating water. When the water circulation system is turned on, water circulates between the indoor heat exchanger 31 and the outdoor heat exchanger. After exchanging heat with the refrigerant circulation system, the water enters the indoor heat exchanger 31 and exchanges heat with the air in the duct to regulate the temperature of the air in the duct. It should be noted that the heat exchange connection between the refrigerant circulation system and the outdoor heat exchanger is a non-mass transfer heat exchange connection, meaning that the water and refrigerant circulate independently, and heat is transferred between them without mixing.

[0071] The water circulation system may also include a water pump, which is located in the connecting pipe between the indoor heat exchanger and the outdoor heat exchanger. When the water pump is turned on, it can drive liquid water to circulate between the indoor heat exchanger and the outdoor heat exchanger.

[0072] Specifically, the refrigerant circulation system includes a compressor, a first heat exchanger, a throttling device, and a second heat exchanger connected in sequence via pipelines, wherein the first heat exchanger is connected to the outdoor heat exchanger for heat exchange. When the compressor is turned on, the refrigerant circulates between the compressor, the first heat exchanger, the throttling device, and the second heat exchanger. The refrigerant flowing through the first heat exchanger can exchange heat with the water in the outdoor heat exchanger in the water circulation system to regulate the temperature of the circulating water in the water circulation system.

[0073] Furthermore, the refrigerant circulation system may also include a four-way valve to allow the air conditioner to switch between cooling and heating modes. Specifically, the compressor's discharge port, return port, one end of the first heat exchanger, and one end of the second heat exchanger are connected to the four ports of the four-way valve. The four-way valve has different valve positions, each corresponding to a different heat exchange mode of the air conditioner. When the four-way valve is in the first position, the air conditioner is in heating mode. The refrigerant from the compressor discharge port passes sequentially through the first heat exchanger, the throttling device, and the second heat exchanger before returning to the compressor from the return port. The first heat exchanger is in a condensing state and exchanges heat with the water in the outdoor heat exchanger of the water circulation system to increase the temperature of the circulating water in the water circulation system. The high-temperature water exchanges heat with the air in the air duct to increase the air temperature. When the four-way valve is in the second position, the air conditioner is in cooling mode. The refrigerant from the compressor discharge port passes through the second heat exchanger, the throttling device and the first heat exchanger in sequence, and then flows back to the compressor from the compressor return port. The first heat exchanger is in the evaporation state. The first heat exchanger exchanges heat with the water in the outdoor heat exchanger in the water circulation system to reduce the temperature of the circulating water in the water circulation system. The low-temperature water exchanges heat with the air in the air duct to reduce the temperature of the air.

[0074] Furthermore, the air conditioner may also include a temperature detection module 5, which is used to detect relevant temperature parameters during the operation of the air conditioner. Specifically, the temperature detection module 5 includes a first temperature sensor, which may be located at the air outlet 22 to detect the current air outlet temperature of the air conditioner. The temperature detection module 5 may also include a second temperature sensor, which may be located at the indoor heat exchanger 31 to detect the indoor heat exchanger temperature. The temperature detection module 5 may also include a third temperature sensor, which may be located in the indoor environment to detect the indoor ambient temperature.

[0075] Furthermore, refer to Figure 2 The air conditioner may also include a control device, to which the aforementioned radiant 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 radiant module 1 and heat pump module 3, and can also be used to acquire temperature detection data from the temperature detection module 5.

[0076] In this embodiment of the invention, reference is made to Figure 2 The control device may include a processor 1001 (e.g., 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 or a stable memory (non-volatile memory), such as a disk storage device. Optionally, the memory 1002 may also be a storage device independent of the aforementioned processor 1001.

[0077] Those skilled in the art will understand that Figure 2 The device structure shown does not constitute a limitation on the device and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0078] like Figure 2 As shown, the memory 1002, which is a computer-readable storage medium, may include a control program for an air conditioner. Figure 2 In the device shown, the processor 1001 can be used to call the control program of the air conditioner stored in the memory 1002 and execute the relevant steps of the control method of the air conditioner in the following embodiments.

[0079] This invention also provides a control method for an air conditioner, which is used to control the operation of the air conditioner.

[0080] Reference Figure 3 This application proposes an embodiment of a control method for an air conditioner. In this embodiment, the air conditioner includes a radiant module and a heat pump module, the heat pump module includes an indoor heat exchanger, and the control method for the air conditioner includes:

[0081] Step S10: Obtain the operating mode of the air conditioner;

[0082] Air conditioners can be divided into different operating modes based on different target air conditioning needs. In this embodiment, the air conditioner's operating modes are divided into cooling mode and heating mode.

[0083] Specifically, the operating mode of an air conditioner can be determined by obtaining user input commands, or by monitoring indoor scene data and determining the current operating mode of the air conditioner based on the monitored indoor scene data.

[0084] In heating mode, the heat pump module operates to provide heat, the indoor heat exchanger is in a condensing state and releases heat, and the air in the duct exchanges heat with the indoor heat exchanger and its temperature rises.

[0085] Step S20: When the operating mode is heating mode, control the radiant module to turn on. When the radiant module is turned on, it heats the air on the air inlet side of the indoor heat exchanger (e.g., near the return air vent).

[0086] Specifically, the radiant module can be turned on during the start-up phase of the heating mode, when the heating mode enters the defrost mode, or continuously during the heating mode. It can also be turned on when the indoor heat exchanger temperature is detected to be lower than a set threshold.

[0087] After the radiant module is turned on, it can operate according to the preset default parameters, or it can operate according to the operating parameters determined by the actual operating conditions of the air conditioner. For example, the operating parameters after the radiant module is turned on can be determined by the surface temperature of the radiant module, the temperature of the indoor heat exchanger, the indoor ambient temperature, and / or the duration of heating operation.

[0088] In this embodiment, the vent on the radiant module serves as the return air vent of the air conditioner. Indoor air enters the return air vent and first passes through the radiant module, which releases radiation waves to heat the air. The heated air is then blown towards the indoor heat exchanger, which further heats the air through heat exchange. The heated air is then delivered into the indoor environment through the air outlet. In other embodiments, the radiant module may not have a vent. Instead, it is positioned between the indoor heat exchanger and the return air vent. Air entering the duct from the return air vent passes sequentially through the radiant module and the indoor heat exchanger for heating before being delivered into the indoor environment through the air outlet.

[0089] This invention proposes a control method for an air conditioner. Based on an air conditioner equipped with a radiant module, when the air conditioner is operating in heating mode, the radiant module is activated to control the air intake side of the indoor heat exchanger. This significantly increases the heat carried by the air after heat exchange in the indoor heat exchanger, thereby compensating for the insufficient heating capacity of the heat pump cycle. Even under poor operating conditions or when users have restrictions on the operation of the heat pump cycle due to wind feel or noise, the heating capacity of the air conditioner can be effectively increased through the cooperation of the radiant module and the indoor heat exchanger. This effectively improves the heating efficiency of the air conditioner, ensures rapid temperature rise in the indoor environment, and enhances the comfort of indoor users during air conditioning heating operation.

[0090] Among them, the radiation module can effectively increase the outlet air temperature. When there is more than one outlet in the air conditioner, it can be combined with dual air ducts to quickly heat the indoor air, improve the temperature fluctuation during the defrosting stage in the heating mode, and also supplement the body heat to improve the comfort of indoor users during the heating process.

[0091] Furthermore, based on the above embodiments, another embodiment of the control method for the air conditioner of this application is proposed. In this embodiment, as... Figure 1 As shown, the radiant module is located at the return air vent of the air conditioner, and the air conditioner has at least two air outlets, each of which is equipped with an air guide. Specifically, in this embodiment, the return air vent of the air conditioner includes several ventilation openings that penetrate the radiant module. When the radiant module is turned on, it heats the air entering the indoor heat exchanger from the return air vent. (Refer to...) Figure 4 After step S20, the method further includes:

[0092] Step S30: With the radiation module in the on state, obtain the first target air outlet temperature of the air conditioner;

[0093] The first target air outlet temperature here is the target value that the air outlet temperature needs to reach under the current heating state of the air conditioner.

[0094] The first target air outlet temperature can be determined by obtaining user commands. For example, if the user inputs a control command for high-temperature airflow, the first target air outlet temperature can be determined to be greater than the first preset temperature. If no control command for high-temperature airflow is input by the user, the first target air outlet temperature can be determined to be less than or equal to the first preset temperature. Alternatively, the number of times the air conditioner's temperature-raising command appears within a preset time period can be obtained. If the number of occurrences is greater than or equal to the set number, the first target air outlet temperature can be determined to be greater than the first preset temperature. If the number of occurrences is less than the set number, the first target air outlet temperature can be determined to be less than or equal to the first preset temperature.

[0095] In addition, the first target air outlet temperature can also be determined by monitoring the operating conditions of the environment in which the air conditioner is located. For example, if the detected indoor ambient temperature is lower than the preset ambient temperature, the first target air outlet temperature can be determined to be higher than the first preset temperature; if the detected indoor ambient temperature is higher than or equal to the preset ambient temperature, the first target air outlet temperature can be determined to be lower than or equal to the first preset temperature.

[0096] Step S40: Determine at least two first target air outlet directions corresponding to the first target air outlets based on the first target air outlet temperature; the return air inlets corresponding to different first target air outlet directions have different air inlet states;

[0097] The first target air outlet direction is specifically the direction formed by the combined air outlet directions of at least two air outlets, which enables the air conditioner's outlet air temperature to reach the first target outlet air temperature. Specifically, the first target air outlet direction can be a set of sub-target air outlet directions corresponding to each air outlet. For example, if the air outlets include at least a first air outlet and a second air outlet, then the first target air outlet direction includes the first sub-target air outlet direction corresponding to the first air outlet and the second sub-target air outlet direction corresponding to the second air outlet.

[0098] Different target air outlet temperatures correspond to different target air outlet directions. Under different target air outlet directions, each outlet has a different position relative to the return air inlet, resulting in different airflow volumes and / or airflow velocities at the return air inlet. The higher the target air outlet temperature, the higher the corresponding airflow volume and / or airflow velocity at the return air inlet can be.

[0099] Specifically, the target air outlet direction can be characterized by the angle between the target air outlet direction and the reference direction (such as the horizontal direction, the vertical direction, or other arbitrarily specified direction). Based on this, a mapping relationship, calculation relationship, and other correspondence between the first target air outlet temperature and the angle corresponding to the first target air outlet direction can be established in advance. Based on this correspondence, the angle corresponding to the first target air outlet direction can be determined by the current first target air outlet temperature, thereby obtaining the first target air outlet direction.

[0100] Step S50: Control at least two of the air guides to operate according to the first target air outlet direction so that the air outlet temperature of the air conditioner is greater than or equal to the first target air outlet temperature.

[0101] Specifically, the target air guide position of each air guide component is determined based on the first target air outlet direction, and each air guide component is controlled to operate according to the corresponding target air guide position so that the air outlet direction formed by at least two air outlets is the first target air outlet direction.

[0102] In this embodiment, since the radiant module can heat the air entering through the air return vent of the air conditioner, different air intake states of the air return vent can result in different heating adjustment effects of the radiant module. Based on the target air outlet temperature of the air conditioner, the air outlet direction of at least two air outlets is controlled, thereby enabling the air intake state of the air return vent to change with the first target air outlet temperature. This ensures that the air outlet temperature can accurately reach the first target air outlet temperature during the air conditioner's heating state, improving the heating efficiency of the air conditioner while ensuring the comfort of the air outlet.

[0103] Specifically, in this embodiment, step S40 includes: when the first target air outlet temperature is greater than the first preset temperature, determining that the first target air outlet direction is one of the at least two air outlets directed towards the air inlet area corresponding to the return air outlet, and the other of the at least two air outlets directed towards an area outside the air inlet area; when the first target air outlet temperature is less than or equal to the first preset temperature, determining that the first target air outlet direction is both of the at least two air outlets directed towards an area outside the air inlet area.

[0104] The first preset temperature here refers to the same temperature as the first preset temperature mentioned above. This first preset temperature can be a parameter set by default in the system, or it can be a parameter set by the user.

[0105] Specifically, the radiant module has two radiant surfaces positioned opposite each other, with ventilation holes extending through both surfaces. Based on this, the set of locations in the indoor environment whose distance from the radiant surface furthest from the indoor heat exchanger is less than or equal to a set distance threshold is defined as the air intake zone. Figure 5 The area enclosed by the dotted lines in the diagram.

[0106] In this embodiment, as Figure 1 The air conditioner has at least two air outlets, including an upper air outlet and a lower air outlet, with a return air inlet located between the upper and lower air outlets. When the first target air outlet temperature is greater than the first preset temperature, the first target air outlet direction can be that the upper air outlet outlet directs airflow diagonally downwards (the air outlet direction of the upper air outlet does not intersect with the air inlet direction of the return air inlet), and the lower air outlet outlet outlet directs airflow towards the air inlet area. The specific first target air outlet direction is as follows: Figure 5 As shown in (a); the first target air outlet direction can be an upper air outlet facing the air inlet area, or a lower air outlet facing downwards (the air outlet direction of the lower air outlet does not intersect with the air inlet direction of the return air outlet). The specific first target air outlet direction is as follows: Figure 5 As shown in (b). When the first target air outlet temperature is less than or equal to the first preset temperature, the first target air outlet direction can be such that the air outlet direction of the upper air outlet and the air outlet direction of the lower air outlet do not intersect with the air inlet direction of the return air inlet. The specific first target air outlet direction is as follows: Figure 6 (a) and Figure 6 As shown in (b). When the air outlet is vented downwards, it facilitates the diffusion of hot air in the indoor environment, effectively improving the heating efficiency and temperature uniformity of the air conditioner.

[0107] In this embodiment, when the first target air outlet temperature is high, some air outlets direct airflow towards the air inlet area of ​​the return air vent. This allows the radiant module, in conjunction with the indoor heat exchanger, to circulate and heat a portion of the air outlet from the air conditioner. The heated air is then delivered into the indoor environment through areas outside the air inlet area of ​​the return air vent, effectively increasing the air outlet temperature of the air conditioner. This ensures the air outlet temperature reaches above the first preset temperature, further improving the air conditioner's heating efficiency to meet the high-temperature air demand of indoor users and enhance their thermal comfort during air conditioning operation. Conversely, when the first target air outlet temperature is low, all air outlets direct airflow towards areas outside the air inlet area of ​​the return air vent. This increases the air volume and range of the air conditioner, allowing the indoor temperature to quickly reach a uniform level. This ensures the radiant module enables the air conditioner to heat quickly while further improving the thermal comfort of users in different locations within the room.

[0108] Furthermore, in this embodiment, the at least two air outlets correspond to at least two fans, and the air outlets and fans are configured in a one-to-one correspondence. A first fan is defined as the fan at the air outlet that directs airflow towards the air inlet area, and a second fan is defined as the fan at the air outlet that directs airflow towards an area outside the air inlet area. After the step of controlling the operation of the at least two air guides according to the first target airflow direction, the method further includes:

[0109] Step S501: Obtain the current air outlet temperature of the air conditioner;

[0110] The current air outlet temperature is obtained by acquiring data from a temperature sensor located at the air outlet of the air conditioner.

[0111] Step S502: Determine the first speed of the first fan and the second speed of the second fan based on the target temperature difference value; the first speed is less than the second speed; the target temperature difference value is the temperature difference between the current outlet air temperature and the first target outlet air temperature;

[0112] The target temperature difference is specifically the absolute value of the difference between the current outlet air temperature and the first target outlet air temperature.

[0113] Different target temperature difference values ​​correspond to different first and second rotational speeds. The correspondence between the target temperature difference value and the first and second rotational speeds can be a mapping relationship, a calculation relationship, etc. Based on this correspondence, the first and second rotational speeds corresponding to the current target temperature difference value can be determined.

[0114] Specifically, the quantitative relationship between the first and second rotational speeds differs depending on the target temperature difference value. In this embodiment, different target temperature difference values ​​result in different ratios between the first and second rotational speeds, while the rotational speed difference between the first and second speeds can be fixed at a preset value. Based on this, by determining the rotational speed ratio between the first and second speeds using the target temperature difference value, the first and second rotational speeds can be determined based on the preset rotational speed difference. In other embodiments, different target temperature difference values ​​result in different rotational speed differences between the first and second speeds. Based on the rotational speed difference and the preset rotational speed sum between the first and second speeds, the first and second rotational speeds corresponding to the current target temperature difference value can be calculated.

[0115] Step S503: Control the first fan to run at the first speed and control the second fan to run at the second speed.

[0116] In this embodiment, the rotation speeds of the fan supplying air to the air intake area and the fan supplying air to areas outside the air intake area are adjusted based on the temperature difference between the current air outlet temperature and the first target air outlet temperature, so that the air outlet of the air conditioner can accurately reach the first target air outlet temperature through the cooperation of at least two fans, thereby further improving the thermal comfort of indoor users.

[0117] Furthermore, based on any of the above embodiments, another embodiment of the control method for the air conditioner of this application is proposed. In this embodiment, the radiant module is disposed at the return air vent of the air conditioner. After the step of controlling the radiant module to turn on when the operating mode is heating mode, the method further includes:

[0118] Step S301: If the air conditioner is in the defrosting stage of the heating mode, and the radiant module is in the on state, control at least one air outlet of the air conditioner to send air towards the air inlet area corresponding to the return air outlet.

[0119] The definition of the air intake area here is the same as in the above embodiment, and will not be repeated here.

[0120] Specifically, when an air conditioner has one air outlet, it can be controlled to direct airflow towards the air intake area of ​​the return air vent. When an air conditioner has more than one air outlet, it can be controlled to direct airflow towards the air intake area of ​​the return air vent, or it can be controlled to direct airflow towards the air intake area of ​​the return air vent.

[0121] In this embodiment, during the defrosting process in heating mode, while the radiant module is turned on to heat the indoor air and replenish the heat needed by the human body, air is sent from the air outlet of the air conditioner towards the air inlet of the return air outlet. This allows the air conditioner to circulate and heat the air outlet through the radiant module, thereby increasing the heat delivered into the indoor environment during the defrosting process, reducing temperature fluctuations in the indoor environment during the defrosting process, and ensuring the comfort of indoor users.

[0122] If the air conditioner is in the non-defrosting stage of the heating mode, the air outlet of the air conditioner can be controlled according to the above steps S30, S40 and S50 and their refinements to improve the heating efficiency of the air conditioner.

[0123] Furthermore, in this embodiment, the air conditioner includes a first air outlet and a second air outlet. The step of controlling at least one air outlet of the air conditioner to deliver air towards the air inlet area corresponding to the return air inlet includes: obtaining the indoor coil temperature of the air conditioner; when the indoor coil temperature is greater than or equal to a set coil temperature, controlling the first air outlet of the air conditioner to deliver air towards the air inlet area, and controlling the second air outlet of the air conditioner to deliver air towards the outer area of ​​the air inlet area. When the indoor coil temperature is less than the set coil temperature, controlling both the first air outlet and the second air outlet to deliver air towards the air inlet area, or controlling the first air outlet to deliver air towards the air inlet area and controlling the second air outlet to close.

[0124] Here, when the coil temperature of the air conditioner is high enough, the air outlet is circulated and heated to increase the intake air temperature, allowing the other outlet to blow slightly higher temperatures, thus accelerating defrosting and providing heating to the room. When the coil temperature is low, the air outlets of both outlets are circulated and heated, or one outlet is circulated and heated while the other is closed. This ensures that no low-temperature air is blown towards the user during the defrosting process. At the same time, the circulating heating ensures that the air conditioner inputs enough heat into the room during the defrosting process, reducing fluctuations in the indoor temperature and ensuring user comfort during defrosting.

[0125] Furthermore, based on any of the above embodiments, another embodiment of the control method for the air conditioner of this application is proposed. In this embodiment, after step S10, the method further includes:

[0126] Step S101: If the air conditioner is in the start-up phase of the heating mode, with the radiation module in the on state, the air guide of the air outlet of the air conditioner is controlled to operate at a first air guide angle; the air outlet direction of the air conditioner corresponding to the first air guide angle is directed towards the area outside the human activity area.

[0127] Step S102: During the operation of the air guide at the first air guide angle, if the temperature of the indoor heat exchanger or the air outlet temperature of the air conditioner is greater than a preset temperature threshold, the air guide is controlled to operate at the second air guide angle; the air outlet direction of the air conditioner corresponding to the second air guide angle is towards the human activity area.

[0128] The human activity area here can be a pre-set fixed area or an area determined based on indoor human information monitored by the air conditioner.

[0129] In this embodiment, as Figure 1 The air conditioner shown is a wall-mounted unit. It can define the area formed by a set of spatial locations with a height greater than or equal to a preset height as the area outside the human activity area; and define the area formed by a set of spatial locations with a height less than a preset height as the human activity area. The first air guide angle corresponds to an air outlet direction facing the direction of the spatial locations with a height greater than or equal to the preset height (i.e., the upper area of ​​the indoor space). The air outlet direction of the air conditioner corresponding to the first air guide angle includes the air inlet area corresponding to the return air vent. The second air guide angle corresponds to an air outlet direction facing the direction of the spatial locations with a height less than the preset height (i.e., the lower area of ​​the indoor space). Based on this, when the heating mode is activated... Figure 1 The air conditioner in the middle can be according to Figure 7 The first airflow angle shown is used when the indoor heat exchanger temperature or the air conditioner's outlet air temperature is high. Figure 1 The air conditioner in the middle can be according to Figure 6The second air guide angle shown indicates air delivery.

[0130] In other embodiments, human information in the indoor space can be identified, and the area where the human body is located can be determined based on the identified human body information. Based on this, the first air guiding angle and the second air guiding angle can both be directed towards the lower area of ​​the indoor space. It is only necessary that the air outlet direction corresponding to the first air guiding angle avoids the human body, and the air outlet direction corresponding to the second air guiding angle is directed towards the human body.

[0131] In this embodiment, during the start-up phase of the heating mode, with the radiant module activated, the air conditioner first avoids blowing air towards the user and then directs air towards the user only when the indoor heat exchanger temperature or the outlet air temperature is high enough. This effectively prevents cold air from blowing into people. The activation of the radiant module also helps to quickly improve the heating efficiency of the air conditioner, which is beneficial for the stability of the indoor heat exchanger or for the air conditioner outlet air temperature to quickly reach the preset temperature threshold. This shortens the duration of the air conditioner's anti-cold air control and ensures that hot air can be quickly blown towards the user, further improving the user's thermal comfort during the air conditioner's heating operation.

[0132] Furthermore, based on any of the above embodiments, another embodiment of the control method for the air conditioner of this application is proposed. In this embodiment, reference is made to... Figure 8 Following S10, the method further includes:

[0133] Step S200: When the operating mode is cooling mode, control the radiation module to shut down.

[0134] In cooling mode, turning off the radiant module helps avoid unnecessary energy consumption while ensuring the air conditioner's cooling effect.

[0135] Specifically, in this embodiment, the radiant module is located between the return air vent of the air conditioner and the indoor heat exchanger. The air conditioner has at least two air outlets, each of which is equipped with an air guide. After step S200, the method further includes:

[0136] Step S300: With the radiation module in the off state, obtain the second target air outlet temperature of the air conditioner;

[0137] The second target outlet air temperature here is the target value that the air outlet temperature needs to reach under the current cooling state of the air conditioner.

[0138] The second target air outlet temperature can be determined by acquiring user commands. For example, if the user inputs a low-temperature air control command, the second target air outlet temperature can be determined to be lower than the second preset temperature. If no user inputs a low-temperature air control command, the second target air outlet temperature can be determined to be greater than or equal to the second preset temperature. Alternatively, the number of times the air conditioner's cooling command appears within a preset time period can be acquired. If the number of occurrences is greater than or equal to the set number, the second target air outlet temperature can be determined to be lower than the second preset temperature. If the number of occurrences is less than the set number, the second target air outlet temperature can be determined to be greater than or equal to the second preset temperature.

[0139] In addition, the second target air outlet temperature can also be determined by monitoring the operating conditions of the environment in which the air conditioner is located. For example, if the detected indoor ambient temperature is greater than the set ambient temperature, the second target air outlet temperature can be determined to be less than the second preset temperature; if the detected indoor ambient temperature is less than or equal to the set ambient temperature, the second target air outlet temperature can be determined to be greater than or equal to the second preset temperature.

[0140] Step S400: Determine at least two second target air outlet directions corresponding to the second target air outlets based on the second target air outlet temperature; the return air inlets corresponding to different second target air outlet directions have different air inlet states;

[0141] The second target air outlet direction is specifically the direction formed by the combined air outlet directions of at least two air outlets, which enables the air conditioner's outlet air temperature to reach the second target outlet air temperature. Specifically, the second target air outlet direction can be a set of sub-target air outlet directions corresponding to each air outlet. For example, if the air outlets include at least a first air outlet and a second air outlet, then the second target air outlet direction includes a third sub-target air outlet direction corresponding to the first air outlet and a fourth sub-target air outlet direction corresponding to the second air outlet.

[0142] Different target air outlet temperatures correspond to different target air outlet directions. Under different target air outlet directions, each outlet has a different position relative to the return air inlet, resulting in different airflow volumes and / or airflow velocities at the return air inlet. The lower the target air outlet temperature, the greater the airflow volume and / or airflow velocity that can be at the return air inlet.

[0143] Specifically, the target air outlet direction can be characterized by the angle between the target air outlet direction and the reference direction (such as the horizontal direction, the vertical direction, or other arbitrarily specified direction). Based on this, a mapping relationship, calculation relationship, and other correspondence between the second target air outlet temperature and the angle corresponding to the second target air outlet direction can be established in advance. Based on this correspondence, the angle corresponding to the second target air outlet direction can be determined by the current second target air outlet temperature, thereby obtaining the second target air outlet direction.

[0144] Step S500: Control at least two of the air guides to operate according to the second target air outlet direction so that the air outlet temperature of the air conditioner is less than or equal to the second target air outlet temperature.

[0145] Specifically, the target air guide position of each air guide component is determined based on the second target air outlet direction, and each air guide component is controlled to operate according to the corresponding target air guide position so that the air outlet direction formed by at least two air outlets is the second target air outlet direction.

[0146] In this embodiment, the temperature regulation effect of the indoor heat exchanger can be different due to the different air intake states of the return air vent. The air outlet direction of at least two air outlets is controlled based on the target air outlet temperature of the air conditioner, so that the air intake state of the return air vent can change with the second target air outlet temperature. This ensures that the air outlet temperature can accurately reach the second target air outlet temperature when the air conditioner is in cooling mode, thereby improving the heating efficiency of the air conditioner while ensuring the air outlet comfort of the air conditioner.

[0147] Specifically, in this embodiment, step S400 includes: when the second target air outlet temperature is less than the second preset temperature, determining that the second target air outlet direction is one of the at least two air outlets directed towards the air inlet area corresponding to the return air outlet, and the other of the at least two air outlets directed towards an area outside the air inlet area; when the second target air outlet temperature is greater than or equal to the second preset temperature, determining that the second target air outlet direction is both of the at least two air outlets directed towards an area outside the air inlet area.

[0148] The second preset temperature here refers to the same temperature as the second preset temperature mentioned above. This second preset temperature can be a parameter set by default in the system, or it can be a parameter set by the user.

[0149] Specifically, the radiant module has two radiant surfaces positioned opposite each other, with ventilation holes extending through both surfaces. Based on this, the set of locations in the indoor environment whose distance from the radiant surface furthest from the indoor heat exchanger is less than or equal to a set distance threshold is defined as the air intake zone. Figure 9 The area enclosed by the dotted lines in the diagram.

[0150] In this embodiment, as Figure 1 The air conditioner has at least two air outlets, including an upper air outlet and a lower air outlet, with a return air inlet located between the upper and lower air outlets. When the second target air outlet temperature is lower than the second preset temperature, the second target air outlet direction can be that the upper air outlet outlet directs airflow diagonally downwards (the air outlet direction of the upper air outlet does not intersect with the air inlet direction of the return air inlet), and the lower air outlet outlet outlet directs airflow towards the air inlet area. The specific second target air outlet direction is as follows: Figure 9As shown in (a); the second target air outlet direction can be an upper air outlet facing the air inlet area, or a lower air outlet facing downwards (the air outlet direction of the lower air outlet does not intersect with the air inlet direction of the return air outlet). The specific second target air outlet direction is as follows: Figure 9 As shown in (b). When the second target air outlet temperature is greater than or equal to the second preset temperature, the second target air outlet direction can be such that the air outlet direction of the upper air outlet and the air outlet direction of the lower air outlet do not intersect with the air inlet direction of the return air inlet. The specific second target air outlet direction is as follows: Figure 10 (a) and Figure 10 As shown in (b). When the air outlet is directed towards the upper part of the space, it is beneficial for the cold air to diffuse in the indoor environment, effectively improving the cooling efficiency and temperature uniformity of the air conditioner.

[0151] In this embodiment, when the second target air outlet temperature is low, some air outlets direct airflow towards the air inlet area of ​​the return air vent. This allows the indoor heat exchanger to circulate and cool a portion of the air outlet from the air conditioner. The circulated and cooled air is then delivered into the indoor environment through areas outside the air inlet area of ​​the return air vent, effectively reducing the air outlet temperature of the air conditioner. This ensures that the air outlet temperature reaches below the second preset temperature, further improving the cooling efficiency of the air conditioner to meet the low-temperature air requirements of indoor users and enhance user comfort during air conditioning operation. Conversely, when the second target air outlet temperature is high, all air outlets direct airflow towards areas outside the air inlet area of ​​the return air vent. This increases the air volume and range of the air conditioner, allowing the indoor temperature to quickly reach a uniform level. This ensures that the radiant module enables the air conditioner to cool rapidly while further improving the temperature comfort of users in different locations within the room.

[0152] Furthermore, this invention also proposes a computer-readable storage medium storing a control program for an air conditioner. When the control program is executed by a processor, it implements the relevant steps of any of the above-described air conditioner control methods.
