[0001] This invention relates to the field of air conditioning technology, and more particularly to a control method for an air conditioner, an air conditioner, and a computer-readable storage medium. Background Technology

[0002] With the development of economy and technology, the application of air conditioners has become increasingly widespread. Air conditioners use an indoor heat exchanger in a heat pump cycle to exchange heat with the air, and then send the heated air into the indoor environment through a fan, thus regulating the indoor air temperature. When the air conditioner is operating in a low-temperature environment for heating, the outdoor unit is prone to frosting, requiring defrosting operation to remove the frost from the outdoor unit.

[0003] When an air conditioner is defrosting, the indoor heat exchanger switches to evaporation mode. The air conditioner cannot maintain heat output to the indoor environment and may even output cooling, which can easily lead to a significant drop in indoor temperature and affect the comfort of indoor users. Summary of the Invention

[0004] The main objective of this invention is to provide a control method for an air conditioner, an air conditioner, and a computer-readable storage medium, which aims to prevent a significant drop in indoor temperature during the defrosting process of the air conditioner, thereby ensuring the comfort of indoor users while the air conditioner defrosts.

[0005] To achieve the above objectives, the present invention provides a control method for an air conditioner, the air conditioner comprising a radiant module and a heat pump module, the heat pump module being used to regulate indoor air temperature through heat exchange, and the radiant module being used to release radiant waves to heat indoor air or supplement the heat required by the human body.

[0036] Optionally, the heat pump module includes a refrigerant circulation system and a water circulation system.

[0046] 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

[0047] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0048] The main solution of this invention is: based on an air conditioner equipped with a radiation module and a heat pump module, the heat pump module is used to regulate the indoor air temperature through heat exchange, and the radiation module is used to release radiation waves to heat the indoor air or supplement the heat required by the human body, and the operating mode of the air conditioner is obtained; when the operating mode is defrosting mode, the heat pump module is controlled to defrost and the radiation module is turned on.

[0049] In existing technology, when an air conditioner is defrosting, the indoor heat exchanger switches to evaporation mode. The air conditioner cannot maintain heat output to the indoor environment and may even output cooling, which can easily lead to a significant drop in indoor temperature and affect the comfort of indoor users.

[0050] The present invention provides the above-mentioned solution, which aims to avoid a significant drop in indoor temperature during the defrosting process of the air conditioner, and to ensure the comfort of indoor users while defrosting the air conditioner.

[0051] 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.

[0052] 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 or supplement the body's heat needs. In this embodiment, the radiation module 1 is an infrared radiation module 1, which releases infrared rays to heat indoor air or supplement the body's heat needs.

[0053] The air conditioner may also include a housing 2 and a heat pump module 3, which is used to regulate air temperature through heat exchange. 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, and 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.

[0054] The number of air outlets 22 can be set according to actual needs, and can be one, two or more.

[0055] The radiant module 1 can be installed on the outer wall of the housing 2 or as part of the housing 2, or it can be installed inside the air duct. When the radiant module 1 is installed on the outer wall of the housing 2 or as part of the housing 2, the radiant waves emitted by the radiant module 1 can be directly released into the indoor environment to heat the air in the indoor environment. When the radiant module 1 is installed inside the air duct, it can cooperate with the indoor heat exchanger 31 to heat the indoor air entering the air duct, and the heated air is sent into the indoor environment from the air outlet 22.

[0056] 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. Furthermore, the ventilation openings on the radiant module 1 can serve as return air inlets 21 for heating the return air; alternatively, they can be used as outlet air inlets 22 for heating the outlet air. The radiant module 1 may also be equipped with valves to open or close these ventilation openings.

[0057] The radiation module 1 may be equipped with a reflective layer, which can reflect the radiation generated by the radiation module 1. Specifically, the reflective layer is located on the side of the radiation module 1 close to the indoor heat exchanger 31, so as to reflect the radiation away from the indoor heat exchanger 31 (i.e., the indoor environment), thereby improving the utilization rate of the radiation and improving the heating efficiency of the radiation module 1.

[0058] 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.

[0059] In one embodiment of the air conditioner, such as Figure 1 As shown in (a), the radiation module 1 is fixedly installed on the outside of the housing 2. The air entering the duct from the return air inlet 21 is heated by the indoor heat exchanger 31 and then sent into the indoor environment through the air outlet 22. In addition, the radiation module 1 installed on the outside of the housing 2 releases radiation waves to directly heat the air near the housing 2.

[0060] In another embodiment of the air conditioner, such as Figure 1 As shown in (b), the radiant module 1 is located inside the air duct, and multiple vents can serve as return air vents 21 for 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 sent into the indoor environment from the air outlet 22.

[0061] In another embodiment of the air conditioner, such as Figure 1 As shown in (c), the radiation module 1 is movably mounted on the housing 2. Specifically, the radiation module 1 can be mounted on the housing 2 via a rotating shaft. The radiation module 1 has a first state and a second state. In the first state, the radiation module 1 is attached to the outer surface of the housing 2; in the second state, the radiation module 1 rotates away from the housing 2 so that the radiating surface faces the front of the housing 2. In this embodiment, the radiation module 1 can rotate relative to the housing 2 between the first and second states. In the first state, the radiation module 1 is not working and is moved to be attached to the outer surface of the housing 2, ensuring the compactness of the overall appearance and reducing the exposed area and dust adhesion. In the second state, the radiation module 1 is turned on, and the radiating surface faces the outside to radiate heat. At this time, the radiation module 1 is rotated away from the outer surface of the housing 2 so that the radiating surface faces the front of the housing 2, thereby realizing rapid radiative heating of the air in the front space area of ​​the housing 2. It can be understood that in the second state, the radiation module 1 can be fixed in a fixed position or can be rotated and adjusted within a certain area to further expand the range of heat radiated by the radiating surface.

[0062] The angle of rotation of the radiation module 1 relative to the outer surface of the housing 2 is defined as α, which satisfies α∈[0°, 100°].

[0063] Understandably, in the first state, the angle between the radiation module 1 and the outer surface of the housing 2 is 0°; in the second state, the radiation module 1 can rotate outward relative to the outer surface of the housing 2 to a preset position, wherein the preset position is within the range of angle α, and can be arbitrarily adjusted within α, so that the radiation surface can be fixed at a certain position within [0°, 100°] to radiate heat into the room, or the radiation position can be arbitrarily adjusted within the range of [0°, 100°] to expand the heat radiation range. Optionally, the rotation angle of the radiation module 1 relative to the outer surface of the housing 2 cannot be too large, otherwise it may cause the radiation surface to move too far and face the top or back of the housing 2, resulting in poor heat radiation effect.

[0064] 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.

[0065] 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.

[0066] In another embodiment of heat pump module 3, refer to Figure 2 The heat pump module 3 may include a refrigerant circulation system 301 and a water circulation system 302. The water circulation system 302 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 301 is connected to the outdoor heat exchanger for heat exchange. The pipes in the water circulation system 302 are filled with liquid water, while the pipes in the refrigerant circulation system 301 are filled with a refrigerant such as a fluoride (e.g., Freon). When the refrigerant circulation system 301 is activated, the refrigerant circulates and exchanges heat with the water in the outdoor heat exchanger to regulate the temperature of the water circulating in the water circulation system 302. When the water circulation system 302 is activated, water circulates between the indoor heat exchanger 31 and the outdoor heat exchanger. After exchanging heat with the refrigerant circulation system 301, 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 301 and the outdoor heat exchanger is a non-mass transfer heat exchange connection, which means that the water and refrigerant circulate independently and transfer heat to each other without mixing.

[0067] The water circulation system 302 may also include a circulating water pump, which is located in the connecting pipe between the indoor heat exchanger and the outdoor heat exchanger. When the circulating water pump is turned on, it can drive liquid water to circulate between the indoor heat exchanger and the outdoor heat exchanger.

[0068] In this embodiment, the outdoor heat exchanger in the refrigerant circulation system 301 and the water circulation system 302 are connected in the heat exchange device 01 for heat exchange.

[0069] Specifically, the refrigerant circulation system 301 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 302 to regulate the temperature of the circulating water in the water circulation system 302.

[0070] Furthermore, the refrigerant circulation system 301 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's return port, one end of the first heat exchanger, and one end of the second heat exchanger are respectively connected to the four ports of the four-way valve. The four-way valve has different valve positions, and different valve positions correspond to different heat exchange modes of the air conditioner. When the four-way valve is in the first valve position, the air conditioner is in heating mode. The refrigerant from the compressor discharge port passes through the first heat exchanger, the throttling device, and the second heat exchanger in sequence, and then flows back to the compressor from the compressor's return port. The first heat exchanger is in a condensing state. The first heat exchanger exchanges heat with the water in the outdoor heat exchanger in the water circulation system 302 to increase the temperature of the circulating water in the water circulation system 302. 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 302 to reduce the temperature of the circulating water in the water circulation system 302. The low-temperature water exchanges heat with the air in the air duct to reduce the temperature of the air.

[0071] Furthermore, the air conditioner may also include a temperature detection module 5, which is used to detect the characteristic temperatures related to the operation of the radiation module 1. 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 disposed on the surface of the radiation module 1 to detect the temperature of the radiation module 1. The second temperature sensor is disposed on the indoor heat exchanger 31 to detect the temperature of the indoor heat exchanger 31. The third temperature sensor is disposed in the indoor environment or on the outside of the housing 2 to detect the indoor ambient temperature.

[0072] Furthermore, the air conditioner may also include a water temperature sensor 6, which may be located in the indoor heat exchanger to detect the water temperature of the indoor heat exchanger.

[0073] Furthermore, the air conditioner may also include a water inlet pipe, which connects the water circulation system to a hot water device (such as a gas water heater, solar water heater, heat pump water heater, or electric water heater) outside the air conditioner. A first hot water pump 7 may be installed on the water inlet pipe, which, when turned on, can supply hot water to the water circulation system.

[0074] Furthermore, the air conditioner may also include a water outlet pipe, which connects the water circulation system to a hot water device (such as a gas water heater, solar water heater, heat pump water heater, or electric water heater) outside the air conditioner. A second hot water pump 8 may be installed on the water outlet pipe. When the second hot water pump 8 is turned on, it introduces part of the hot water from the water circulation system into the hot water device, while the other part of the hot water circulates between the indoor heat exchanger 31 and the outdoor heat exchanger.

[0075] Furthermore, refer to Figure 3 The air conditioner may also include a control device, to which the aforementioned radiant module 1, heat pump module 3, temperature detection module 5, water temperature sensor 6, first hot water pump 7, and second hot water pump 8 are all connected. The refrigerant circulation system 301 and the water circulation system 302 are both connected to the control device. The control device can be used to control the operation of the radiant module 1, heat pump module 3, first hot water pump 7, and second hot water pump 8, and can also be used to acquire temperature detection data from the temperature detection module 5 and water temperature sensor 6.

[0076] In this embodiment of the invention, reference is made to Figure 3 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 3 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 3 As shown, the memory 1002, which is a computer-readable storage medium, may include a control program for an air conditioner. Figure 3 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 air conditioner described above.

[0080] Reference Figure 4 This application proposes an embodiment of a control method for an air conditioner. In this embodiment, 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 air conditioning needs. In this embodiment, the air conditioner's operating modes are divided into cooling mode, heating mode, and defrosting mode. Cooling mode is a mode that aims to lower the indoor air temperature, heating mode is a mode that aims to raise the indoor air temperature, and defrosting mode is a mode that aims to melt the frost on the outdoor unit of the air conditioner.

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

[0084] Step S20: When the operating mode is defrosting mode, control the heat pump module to defrost and turn on the radiation module.

[0085] In this embodiment, during the defrosting operation of the heat pump module, the refrigerant circulation system in the heat pump module is in a cooling state. Specifically, when the heat pump module is a refrigerant circulation system, during the defrosting operation of the heat pump module, the compressor is turned on, the four-way valve operates in the second valve position, and the refrigerant flowing out of the compressor passes through the outdoor heat exchanger, the throttling device, and the indoor heat exchanger in sequence before flowing back to the compressor. The outdoor heat exchanger is in a condensing state, releasing heat to melt the frost on the outdoor heat exchanger and in the space it occupies, while the indoor heat exchanger is in an evaporating state, absorbing heat.

[0086] During defrosting operation, the indoor fan of the heat pump module can be turned off or on. Specifically, when the radiant module is located inside the air duct, the indoor fan is turned on during the defrosting operation of the heat pump module. The operating speed of the indoor fan during operation can be determined according to the air outlet temperature of the air conditioner. The lower the air outlet temperature, the lower the fan speed can be, and the higher the air outlet temperature, the higher the fan speed can be.

[0087] Specifically, when the radiation module is located in the casing, it can directly release radiation waves to heat the indoor air or supplement the heat needed by the human body when it is turned on; when the radiation module is located in the air duct and on the return air side of the air conditioner, it releases radiation waves to heat the air on the air inlet side of the indoor heat exchanger when it is turned on.

[0088] When the radiant module is turned on, it can operate according to the preset fixed radiant parameters, or it can operate according to the radiant parameters determined by the actual operating conditions of the air conditioner (such as the outlet air temperature, indoor ambient temperature, duration of heating operation, water temperature of the indoor heat exchanger, and / or surface temperature of the radiant module).

[0089] This invention proposes a control method for an air conditioner. The method is based on an air conditioner equipped with a heat pump module and a radiant module. In the defrosting mode of the air conditioner, the heat pump module operates while the radiant module is turned on. During the defrosting process, the radiant module can maintain the transfer of heat to the indoor environment, thereby avoiding a significant drop in indoor temperature during the defrosting process of the air conditioner, and ensuring the comfort of indoor users while the air conditioner defrosts.

[0090] Furthermore, in this embodiment, the radiant module has a through hole connecting the air conditioner's ductwork to the indoor environment. In defrost mode, during step S20, the indoor fan can be controlled to operate in a first direction, and the air guide at the air outlet can be controlled to adjust the air guide angle so that the air outlet direction of the air conditioner is towards the air intake area corresponding to the ventilation hole. When the indoor fan operates in the first direction, indoor air enters the ductwork through the through hole on the radiant module and is sent into the room from the air outlet. Since the air outlet direction is towards the air intake area corresponding to the ventilation hole, the air blown into the indoor environment from the air outlet is circulated and heated by the radiant module, thereby increasing the outlet temperature and increasing the heat input by the air conditioner to the indoor environment during the defrost process. This further avoids fluctuations in the indoor temperature and improves the comfort of indoor users during the defrost process.

[0091] In some cases, when the air conditioner has more than one air outlet, the guide vane of one outlet can be adjusted to direct the airflow towards the air intake area corresponding to the ventilation hole, while the guide vane of another outlet can be adjusted to direct the airflow towards the lower part of the space. This ensures that the heat generated during the defrosting process quickly reaches the user's activity area, guaranteeing comfort. Furthermore, when the air conditioner has more than one air outlet, the guide vane of each outlet can be adjusted to direct the airflow towards the air intake area corresponding to the ventilation hole. This achieves air circulation heating, ensuring sufficient heat is delivered into the room during defrosting to maintain a stable indoor temperature and guarantee user comfort during the defrosting process.

[0092] In addition, the air outlet of the air conditioner can be closed by the air guide in defrosting mode to prevent the cold air after heat exchange in the indoor heat exchanger from entering the room and causing indoor temperature fluctuations, so as to ensure user comfort.

[0093] Furthermore, based on 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 5 After step S20, the method further includes:

[0094] Step S30: Obtain a first temperature and a second temperature of the indoor environment; the first temperature is detected before the air conditioner enters the defrost mode, and the second temperature is detected during the defrost mode.

[0095] Specifically, when the air conditioner is running in heating mode, if a defrost command is issued or the defrost activation conditions are met, the temperature data detected by the indoor temperature sensor is used as the first temperature, and then the air conditioner is controlled to enter defrost mode. During defrost mode operation, the temperature data detected by the indoor temperature sensor is used as the second temperature.

[0096] Step S40: Determine the target operating parameters of the radiation module based on the first temperature and / or the second temperature;

[0097] The target operating parameters here may specifically include control parameters for the radiation power of the radiation module (such as the direction of power adjustment or power value), control parameters for the opening and closing of the radiation module (such as the opening or closing of the radiation module), and the opening duration of the radiation module.

[0098] Specifically, the target operating parameters of the radiation module can be determined based on either the first temperature or the second temperature.

[0099] Different first temperatures and / or different second temperatures correspond to different target operating parameters for the radiant modules. Different target operating parameters result in different heating capacities of the radiant modules for the indoor air.

[0100] The correspondence between the first and / or second temperatures and the target operating parameters can be preset, or it can be obtained based on the current operating parameters of the heat pump module (such as compressor frequency, indoor fan speed, and / or the coil temperature of the first heat exchanger exchanging heat with the outdoor heat exchanger of the water circulation system). Different operating parameters correspond to different correspondences. The correspondence can take the form of mapping relationships, calculation relationships, etc. Based on this correspondence, the target operating parameters of the radiation module corresponding to the current first and / or second temperatures can be determined.

[0101] Step S50: Control the operation of the radiation module according to the target operating parameters.

[0102] If the defrosting mode has not ended after step S50, the process can return to step S30 and continue to regulate the operation of the radiation module in the defrosting mode based on the first temperature and the second temperature.

[0103] In this embodiment, the first temperature reflects the heating demand of the radiant module after defrosting begins, and the second temperature reflects the indoor temperature during the heating process of the radiant module in the current defrosting state. Therefore, by controlling the operation of the radiant module in combination with the first and second temperatures, it can be ensured that the radiant module can output enough heat to maintain the stability of the indoor temperature before and after defrosting begins, avoid large fluctuations in the indoor environment during defrosting, and ensure the thermal comfort of users in the indoor environment during the defrosting process.

[0104] Furthermore, in this embodiment, before step S30, the temperature of the radiation module can be obtained. If the temperature of the radiation module is greater than or equal to a set temperature threshold, the radiation module can be controlled to reduce its radiation power or turn off. If the temperature of the radiation module is less than the set temperature threshold, the radiation module can be controlled to remain on and step S30 can be executed. Based on this, damage to the radiation module due to excessive temperature can be avoided, ensuring that the radiation module meets the user's thermal comfort requirements in defrosting mode while extending the service life of the radiation module.

[0105] Specifically, in this embodiment, step S40 includes:

[0106] Step S41: Determine a first temperature difference between the first temperature and the second temperature, and / or determine a second temperature difference between the second temperature and the set temperature of the air conditioner;

[0107] The set temperature is specifically the target value that the indoor ambient temperature needs to reach during the operation of the air conditioner. In this embodiment, the first temperature difference is the difference between the first temperature and the second temperature; the second temperature difference is the difference between the second temperature and the set temperature. In other embodiments, the first temperature difference is also the absolute value between the first temperature and the second temperature, and the second temperature difference is the absolute value between the second temperature and the set temperature.

[0108] Step S42: Determine the target operating parameters based on the first temperature difference value and / or the second temperature difference value.

[0109] Different first temperature difference values ​​and / or different second temperature difference values ​​correspond to different target operating parameters. In this embodiment, if the first temperature is greater than or equal to the second temperature, and the first temperature is less than or equal to the set temperature, and the target operating parameter is the radiation power of the radiation module, then the radiation power increases with the increase of the first temperature difference value, and decreases with the increase of the second temperature difference value; conversely, the radiation power decreases with the decrease of the first temperature difference value, and increases with the decrease of the second temperature difference value. In other embodiments, the radiation power and the first and second temperature difference values ​​may have other changing patterns or no specific changing patterns.

[0110] In one embodiment, the target operating parameter can be determined based on a first temperature difference value. Specifically, step S42 includes: when the first temperature difference value is greater than a first preset temperature difference, determining the target operating parameter as increasing the radiation power of the radiation module; when the first temperature difference value is less than or equal to the first preset temperature difference, determining the target operating parameter as decreasing the radiation power of the radiation module or maintaining the current radiation power of the radiation module. Here, the first temperature difference value is the difference between a first temperature and a second temperature; the second temperature difference value is the difference between the second temperature and a set temperature.

[0111] In another embodiment, the target operating parameter can be determined based on the second temperature difference value. Specifically, step S42 includes: when the second temperature difference value is greater than a second preset temperature difference, the target operating parameter is determined to be reducing the power of the radiation module; when the temperature difference value is less than or equal to the second preset temperature difference, the target operating parameter is determined to be increasing the power of the radiation module. Here, the first temperature difference value is the difference between the first temperature and the second temperature; the second temperature difference value is the difference between the second temperature and the set temperature.

[0112] In another embodiment, the target operating parameter can be determined based on a first temperature difference value and a second temperature difference value. Here, the first temperature difference value is the difference between a first temperature and a second temperature; the second temperature difference value is the difference between the second temperature and a set temperature. Step S42 specifically includes: when the first temperature difference value is greater than a first preset temperature difference, the target operating parameter is determined to be increasing the radiation power of the radiation module; when the first temperature difference value is less than the first preset temperature difference and the second temperature difference value is greater than a second preset temperature difference, the target operating parameter is determined to be decreasing the radiation power of the radiation module. Furthermore, when the first temperature difference value is less than the first preset temperature difference and the second temperature difference value is less than or equal to the second preset temperature difference, the target operating parameter is determined to be maintaining the radiation power of the radiation module or increasing the radiation power of the radiation module.

[0113] The power adjustment parameters for reducing or increasing radiant power can be preset fixed parameters, or they can be determined based on air conditioner operating characteristic parameters such as radiant module temperature, indoor ambient temperature, indoor heat exchanger temperature, and / or outlet air temperature. Different air conditioners have different power adjustment parameters corresponding to their operating characteristic parameters.

[0114] The radiation power of the radiation module can be increased or decreased by adjusting its input voltage. Increasing the radiation power of the radiation module increases its input voltage, while decreasing the radiation power decreases its input voltage.

[0115] In this embodiment, the first temperature difference value accurately represents the temperature fluctuation of the current indoor environment relative to the indoor environment before defrosting, and the second temperature difference value accurately represents the deviation of the current indoor temperature from the user's comfort temperature. Based on this, determining the target operating parameters of the radiant module according to the first and / or second temperature difference values ​​helps ensure accurate control of the radiant module's operation. This ensures that when the radiant module operates according to the target operating parameters, the heat output can effectively avoid indoor temperature fluctuations while accurately matching the user's comfort needs. Specifically, increasing the radiant power of the radiant module when the first temperature difference is too large helps ensure that the radiant module outputs enough heat to maintain the stability of the indoor temperature before and after defrosting, avoiding temperature fluctuations and ensuring user comfort during the defrosting process. Conversely, when the difference between the first and second temperatures is small and / or the difference between the second temperature and the set temperature is large, the current indoor temperature fluctuation relative to the temperature before defrosting is small and has reached the user's comfort level. In this case, reducing the radiant power of the radiant module helps ensure that the indoor environment remains at the user's comfort level during the defrosting process.

[0116] 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 heat pump module includes a refrigerant circulation system and a water circulation system. The water circulation system includes an indoor heat exchanger and an outdoor heat exchanger. The outdoor heat exchanger is connected to the refrigerant circulation system for heat exchange. When the heat pump module defrosts, the refrigerant circulation system defrosts and exchanges heat with the water in the outdoor heat exchanger. The water after heat exchange circulates between the indoor heat exchanger and the outdoor heat exchanger.

[0117] Furthermore, refer to Figure 6 After step S20, the method further includes:

[0118] Step S60: When the heat pump module is in defrosting mode and the radiant module is turned on, the hot water pump of the air conditioner is turned on. When the hot water pump is turned on, hot water from the hot water device outside the air conditioner is input into the water circulation system.

[0119] The hot water here specifically refers to water with a temperature higher than that in the water circulation system.

[0120] When the hot water pump is turned on, it can run at a fixed speed, or it can run at a speed determined by the compressor frequency of the refrigerant circulation system, the coil temperature of the first heat exchanger, the water temperature of the indoor heat exchanger before the hot water pump is turned on, and / or the current water temperature of the indoor heat exchanger.

[0121] When the heat pump module includes a refrigerant circulation system and a water circulation system, during the defrosting operation of the heat pump module, the compressor in the refrigerant circulation system is turned on, the four-way valve operates in the second valve position, and the refrigerant flowing out of the compressor passes through the second heat exchanger, the throttling device and the first heat exchanger in sequence before flowing back to the compressor. The second heat exchanger is in a condensing state and releases heat to melt the frost on the second heat exchanger and in the space it is in. The first heat exchanger is in an evaporating state and exchanges heat with the outdoor heat exchanger of the water circulation system. During the heat exchange process, the water temperature in the outdoor heat exchanger is reduced, and the low-temperature water circulates between the indoor heat exchanger and the outdoor heat exchanger.

[0122] In this embodiment, during the defrosting process, in addition to activating the radiant module to maintain the air conditioner's input of heat to the indoor environment, heat is also input into the water circulation system to increase the water temperature in the water circulation system, preventing the water volume in the water circulation system from becoming too low during the defrosting process. It can even enable the indoor heat exchanger to transfer heat to the indoor air. In conjunction with the activation of the radiant module, this ensures that the air conditioner's heat output to the indoor environment is further increased during the defrosting process, further preventing the indoor temperature from dropping during the defrosting process, and ensuring the thermal comfort of the indoor users.

[0123] If steps S30 to S50 are included after step S20, then the operation of the radiant module can be controlled according to steps S30 to S50 when the hot water pump, heat pump module, and radiant module are all in the on state.

[0124] Furthermore, in this embodiment, after step S20, the following steps are also included:

[0125] Step S601: When the heat pump modular defrost is running and the radiation module is turned on, obtain the current radiation power of the radiation module and the radiation module temperature of the radiation module.

[0126] Step S602: When the radiation power is greater than the set power, or when the temperature of the radiation module is greater than the preset temperature threshold, execute the step of controlling the hot water pump of the air conditioner to turn on.

[0127] Here, when the radiant power is too high or the radiant module temperature is too high, it indicates that the heat radiated into the air by the radiant module cannot be increased further. If it is increased further, it will damage the radiant module. At this time, by turning on the hot water pump, the external hot water is used to further increase the heating capacity of the air conditioner, so as to ensure that the external hot water and the radiant module work together to ensure the stability of the indoor ambient temperature during the defrosting process, further ensuring the user comfort during the defrosting process and extending the service life of the radiant module.

[0128] In the case of steps S30 to S50 after step S20, if the target operating parameters determined based on the first temperature and the second temperature include increasing the radiation power of the radiation module, steps S601 and S602 are executed here. When the radiation power is less than or equal to the set power and the temperature of the radiation module is less than or equal to the preset temperature threshold, the radiation module can be controlled to operate according to the target operating parameters (i.e., the radiation module can be controlled to increase the radiation power).

[0129] Furthermore, based on the above embodiment, another embodiment of the control method for the air conditioner of this application is proposed. In this embodiment, the water circulation system further includes an indoor fan corresponding to the indoor heat exchanger, as described above. Figure 7 After step S60, the method further includes:

[0130] Step S70: During the process of turning on the hot water pump, the water temperature inside the indoor heat exchanger is obtained;

[0131] The specific water temperature inside the indoor heat exchanger can be obtained by acquiring data from the water temperature sensor installed on the indoor heat exchanger.

[0132] Step S80: Determine the fan control parameters and / or hot water regulation parameters based on the water temperature;

[0133] Fan control parameters are parameters used to control the operation of indoor fans. Specific fan control parameters include the direction of speed adjustment (e.g., increasing speed, decreasing speed, or maintaining speed), the target speed value for fan operation, or fan on / off parameters (e.g., turning the fan on or off).

[0134] Hot water control parameters are control parameters used to regulate the flow rate and / or temperature of hot water supplied by the hot water device to the water circulation system. These parameters can be control parameters for the operation of the hot water pump or the hot water device itself. Hot water control parameters may include the direction of hot water temperature adjustment (e.g., increasing or decreasing the water temperature), the target water temperature value, the direction of hot water pump speed adjustment (e.g., increasing, decreasing, or maintaining the speed), and / or the target value of the hot water pump's operating speed.

[0135] Different water temperatures correspond to different fan control parameters and / or hot water regulation parameters. The correspondence between water temperature and fan control parameters and / or hot water regulation parameters (such as mapping relationships, calculation relationships, etc.) can be preset or obtained based on the current operating parameters of the radiant module (e.g., the surface temperature of the radiant module and / or the radiant power of the radiant module). Different operating parameters of the radiant module correspond to different relationships between water temperature and control parameters. Based on this correspondence, the fan control parameters and / or hot water regulation parameters corresponding to the current water temperature can be determined.

[0136] In the above correspondence, the indoor fan speed corresponding to the fan control parameters increases with increasing water temperature; the hot water temperature input to the water circulation system by the hot water device corresponding to the hot water control parameters increases with decreasing water temperature; and the operating speed of the hot water pump corresponding to the hot water control parameters increases with increasing water temperature. Conversely, the indoor fan speed corresponding to the fan control parameters decreases with decreasing water temperature; the hot water temperature input to the water circulation system by the hot water device corresponding to the hot water control parameters decreases with increasing water temperature; and the operating speed of the hot water pump corresponding to the hot water control parameters decreases with decreasing water temperature. In other embodiments, the relationship between water temperature and the fan speed corresponding to the fan control parameters and / or the hot water temperature and water volume corresponding to the hot water control parameters may have other patterns or no clear pattern.

[0137] Step S90: Control the operation of the indoor fan according to the fan control parameters, and / or control the operation of the hot water pump and / or the hot water device according to the hot water regulation parameters.

[0138] In this embodiment, different fan control parameters can result in different heat exchange efficiencies in the indoor heat exchanger, and different hot water control parameters can result in different amounts of heat input from the hot water device to the water circulation system. Based on this, the operation of the fan, water pump, and / or hot water device is adjusted according to the current water temperature of the indoor heat exchanger. This ensures that during the process of increasing heat through external water supply, the hot water device can provide sufficient heat for the heat exchange between the indoor heat exchanger and the air. It also ensures that the heat exchange efficiency of the indoor heat exchanger controlled by the fan can match its heat supply, ensuring that the air temperature after heat exchange and adjustment by the indoor heat exchanger is high enough, and ensuring the comfort of the air outlet during the heating process of the air conditioner.

[0139] After step S90, the current indoor temperature can be obtained, and the operating parameters of the radiation module are determined based on the third temperature difference between the current indoor temperature and the set temperature. In this embodiment, the third temperature difference is the absolute value of the difference between the indoor temperature and the set temperature. Specifically, the operating parameter here is the radiation power of the radiation module. When the indoor temperature is lower than the set temperature, the radiation power increases with the increase of the third temperature difference and decreases with the decrease of the third temperature difference. Based on this, it is beneficial to ensure that the heat dissipation output of the air conditioner can accurately match the actual needs of the user in the indoor environment, and improve the user comfort during the defrosting process.

[0140] Furthermore, in this embodiment, the fan control parameters include the rotational speed of the indoor fan, and the rotational speed of the indoor fan increases with the increase of the water temperature.

[0141] Specifically, when the water temperature is less than or equal to the first preset temperature, the fan control parameters are determined to maintain the speed of the indoor fan or reduce the speed of the indoor fan; when the water temperature is greater than the second preset temperature, the fan control parameters are determined to increase the speed of the indoor fan; the second preset temperature is greater than or equal to the first preset temperature.

[0142] The first preset temperature and the second preset temperature can be fixed temperatures set in advance, or they can be temperatures selected from multiple preset temperatures based on the current operating parameters of the radiation module (e.g., the surface temperature of the radiation module and / or the radiation power of the radiation module). In this embodiment, the second preset temperature is greater than the first preset temperature. In other embodiments, the second preset temperature may also be equal to the first preset temperature.

[0143] When the fan speed is reduced or increased, the speed adjustment parameters (such as the speed adjustment range or speed adjustment speed) can be fixed parameters that are preset, or parameters that are determined according to the actual operating conditions of the air conditioner. For example, the speed adjustment parameters when the indoor fan speed is increased or decreased can be determined according to the indoor ambient temperature, the air outlet temperature of the air conditioner, the temperature difference between the current water temperature and the target water temperature, and / or the current operating parameters of the radiation module (such as the surface temperature of the radiation module and / or the radiation power of the radiation module).

[0144] Specifically, when the water temperature is low, if the current speed of the indoor fan is less than the set speed, the indoor fan can be controlled to maintain the current speed; if the current speed of the indoor fan is greater than the set speed, the indoor fan can be controlled to reduce the current speed.

[0145] In this embodiment, when the indoor heat exchanger water temperature is low, it indicates that the heat input from the indoor heat exchanger to the air is insufficient. By maintaining or reducing the indoor fan speed, the indoor fan speed is limited to prevent further increases, thus avoiding excessively low air temperature after heat exchange through the indoor heat exchanger and preventing a large amount of low-temperature air from being blown towards the user, which helps ensure the comfort of the air conditioner's output. When the indoor heat exchanger water temperature is high, it indicates that the indoor heat exchanger has sufficient heat to exchange with the indoor air. At this time, increasing the fan speed helps improve the heat exchange efficiency of the air conditioner and the heating efficiency of the indoor environment.

[0146] Furthermore, in this embodiment, the hot water control parameters include a first operating parameter of the hot water pump and a second operating parameter of the hot water device. Therefore, controlling the operation of the hot water pump and / or the hot water device according to the hot water control parameters includes controlling the hot water pump to operate with the first operating parameter and controlling the hot water device to operate with the second operating parameter. The step of determining the hot water control parameters based on the water temperature includes: when the water temperature is less than or equal to a preset water temperature, determining the second operating parameter to increase the hot water temperature output by the hot water device to the water circulation system; when the water temperature is greater than the preset water temperature, determining the first operating parameter to increase the speed of the hot water pump.

[0147] In this embodiment, the preset water temperature is equal to the first preset temperature mentioned above. In other embodiments, the preset water temperature may also be set to a temperature that is not equal to the first preset temperature.

[0148] The preset water temperature can be a fixed temperature set in advance, or it can be a temperature selected from multiple preset temperatures based on the current operating parameters of the radiation module (such as the surface temperature of the radiation module and / or the radiation power of the radiation module).

[0149] Specifically, the hot water device can increase its operating heating power to increase the temperature of the hot water it outputs to the water circulation system.

[0150] The adjustment parameters for the hot water device to increase the water temperature and / or the speed adjustment parameters for the first hot water pump can be determined based on the temperature difference between the current water temperature and the preset water temperature.

[0151] In this embodiment, when the water temperature is low, the temperature of the hot water supplied by the hot water device is increased by controlling the hot water device, thereby ensuring that the heating efficiency of the air conditioner can be effectively improved when it inputs hot water into the water circulation system. When the water temperature is high, increasing the speed of the hot water pump helps to further increase the heat supply of the hot water device to the water circulation system, thereby effectively improving the heating efficiency of the air conditioner during the defrosting process and further ensuring stable indoor temperature.
