Technical Field

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

[0002] Radiant air conditioning refers to a heating and cooling system that primarily uses thermal radiation and secondarily uses thermal convection. It mainly consists of radiant panels as its core components, supplemented by fresh air systems, main control systems, heat pump systems, etc., and can comprehensively address the needs of indoor environments in terms of temperature, humidity, cleanliness, quietness, oxygen content, and domestic water usage.

[0003] Currently, radiant air conditioners adapt to different ambient temperatures and operate in different modes. When the temperature fluctuates significantly, this can easily lead to frequent switching of operating modes, or even unreasonable operating modes. The radiant terminals of radiant air conditioners are relatively slow to adjust the ambient temperature, and unreasonable operating mode selection can cause the room temperature to deviate significantly from the user's comfort range, affecting the user experience. Summary of the Invention

[0017] Wherein, the first preset temperature is greater than the second preset temperature.

[0018] Optionally, the characteristic parameters include the direction of temperature change and the value of temperature change, the first mode is a cooling mode, the second mode is a heating mode, and after the step of obtaining the temperature value and the characteristic parameters of temperature change of the outdoor environment where the radiant air conditioner is located, the method further includes:

[0019] When the temperature value is less than or equal to a third preset temperature, the temperature change direction is cooling, and the temperature change value is greater than or equal to a third preset amplitude, it is determined that the temperature state parameter has reached the preset switching condition.

[0020] Optionally, after the step of obtaining the temperature value and characteristic parameters of temperature change of the outdoor environment where the radiant air conditioner is located, the method further includes:

[0021] When the temperature value is greater than the fourth preset temperature, or when the temperature value is less than or equal to the third preset temperature, the temperature change direction is rising, and the temperature change value is greater than or equal to the fourth preset amplitude, the count value is reduced and the process returns to the step of obtaining the temperature value and temperature change characteristic parameters of the outdoor environment where the radiant air conditioner is located.

[0033] This invention proposes a control method for a radiant air conditioner. This method acquires the temperature parameters of the outdoor environment during the first operating mode of the radiant air conditioner, counts the number of times the temperature parameters reach the preset switching conditions corresponding to the second mode, and switches the radiant air conditioner to the second mode only when the count value is greater than or equal to the target value; otherwise, it maintains operation in the first mode. Based on this, it can effectively avoid frequent switching between operating modes with different output energy, and can effectively improve the accuracy of the radiant air conditioner's operating mode after switching.

[0040] 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

[0041] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0042] This invention provides a radiant air conditioner for regulating indoor temperature.

[0043] In this embodiment, the radiant air conditioner includes a control device 1, a heat pump system 2, an energy delivery system 3, and a fresh air conditioning system 4. The heat pump system 2, the energy delivery system 3, and the fresh air system 4 are all connected to the control device 1.

[0044] The energy delivery system 3 is used to regulate the temperature of the indoor space using the energy output from the heat pump system 2. The fresh air system 4 is used to introduce fresh air into the indoor space. There may be more than one heat pump system 2, which may include a first heat pump system and a second heat pump system. The first heat pump system is used to provide energy (such as cooling or heating) for heat exchange between the energy delivery system 3 and the indoor space, and the second heat pump system is used to provide energy (such as cooling or heating) for temperature and / or humidity regulation of the fresh air. The number of second heat pump systems may be one or more.

[0045] In this embodiment, the energy delivery system 3 is a water system, and the heat pump system 2 is used to regulate the water supply temperature of the energy delivery system 3, which in turn regulates the indoor temperature. In this embodiment, the water supply temperature of the energy delivery system 3 can be understood as the outlet water temperature of the heat pump system 2. In other embodiments, the energy delivery system 3 may also be a system that uses other media to transfer energy, such as an ethanol solution.

[0046] In this embodiment, the heat pump system 2 is an air source heat pump system 2. In other embodiments, the heat pump system 2 may also be a water source heat pump system, a ground source heat pump system, or a dual-source heat pump system, etc.

[0047] In this embodiment, the heat pump system 2 includes a refrigerant circulation loop, which includes a compressor, a first heat exchanger, a throttling device, and a second heat exchanger. The heat pump system 2 can operate in two modes: a cooling mode and a heating mode. When the heat pump system 2 operates in cooling mode, the second heat exchanger is in an evaporating state to absorb heat, and when the heat pump system 2 operates in heating mode, the second heat exchanger is in a condensing state to release heat.

[0048] The energy transfer system 3 includes a medium circulation loop and terminal heat exchange devices located within the medium circulation loop. These terminal heat exchange devices may include underfloor heating coils, radiant panels, fan coil units, or radiators. The cold or heat energy of the water in the medium circulation loop can be released into the indoor space where the terminal heat exchange device is located. There may be one or more terminal heat exchange devices, and more than one terminal heat exchange device may be distributed across different indoor spaces. The heat exchange types of the terminal heat exchange devices in different indoor spaces may be the same or different. Therefore, the cold or heat energy carried by the medium in the medium circulation loop can be used to regulate the ambient temperature of more than one indoor space.

[0049] The energy transfer system 3 also includes a heat exchange module, with a second heat exchanger connected to the heat exchange module for heat exchange. The medium circulation loop has an inlet and an outlet; the inlet of the medium circulation loop is connected to the outlet of the heat exchange module, and the outlet of the medium circulation loop is connected to the inlet of the heat exchange module. The second heat exchanger and the heat exchange module can be either a shell-and-tube heat exchanger or a plate heat exchanger.

[0050] During the operation of the first heat pump system, the medium in the heat exchange module absorbs the cold or heat released by the second heat exchanger, forming a medium carrying the cold or heat. This medium, carrying the cold or heat, flows out of the heat exchange module and enters the medium circulation loop, flowing to the terminal heat exchange equipment to release the cold or heat into the indoor air, thus regulating the indoor ambient temperature. The medium, having released its cold or heat, can re-enter the heat exchange module to exchange heat with the second heat exchanger, and then re-enter the medium circulation loop. This cycle repeats, thereby achieving radiant air conditioning to regulate the indoor temperature.

[0051] When the first heat pump system is in cooling mode, the second heat exchanger is in an evaporation state. The medium in the heat exchange module absorbs the cold energy output by the second heat exchanger and its temperature decreases, forming a medium carrying the cold energy. The medium carrying the cold energy enters the medium circulation loop and flows to the terminal heat exchange equipment, releasing the cold energy into the indoor space, thus lowering the ambient temperature of the indoor space.

[0052] When the first heat pump system is in heating mode, the second heat exchanger is in a condensation state. The medium in the heat exchange module absorbs the heat output by the second heat exchanger and its temperature rises to form a heat-carrying medium. The heat-carrying medium enters the medium circulation loop and flows to the terminal heat exchange equipment, releasing heat into the indoor space and raising the ambient temperature of the indoor space.

[0053] The second heat exchanger in the second heat pump system can be located within the fresh air duct of the fresh air system. There can be more than one second heat pump system, meaning more than one second heat exchanger can be installed within the fresh air duct of the fresh air system. When the second heat pump system operates in cooling mode, the second heat exchanger is in an evaporating state, and the fresh air introduced by the fresh air system can absorb cooling energy for cooling and / or dehumidification. When the second heat pump system operates in heating mode, the second heat exchanger is in a condensing state, and the fresh air introduced by the fresh air system can absorb heat for heating and / or reheating. When more than one second heat exchanger is located within the fresh air duct, all of the heat exchangers can be in an evaporating state, all can be in a condensing state, or some can be in an evaporating state while others are in a condensing state.

[0054] Furthermore, in this embodiment, referring to Figure 2 The control device 1 can also be connected to the environmental detection module 5. The environmental detection module 5 can include an indoor temperature sensor and / or an outdoor temperature sensor. The indoor temperature sensor can detect the ambient temperature of the indoor space regulated by the radiant air conditioner; the outdoor temperature sensor can detect the ambient temperature of the outdoor space where the radiant air conditioner is located.

[0055] In this embodiment of the invention, reference is made to Figure 2The control device 1 for the radiant air conditioner includes a processor 1001 (e.g., CPU), a memory 1002, a timer 1003, etc. The components in the control device 1 are connected via a communication bus. The memory 1002 can be a high-speed RAM or a stable, non-volatile memory, such as a disk drive. Optionally, the memory 1002 can also be a storage device independent of the aforementioned processor 1001.

[0056] 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.

[0057] like Figure 2 As shown, the memory 1002, which serves as a storage medium, may include a control program for a radiant air conditioner. Figure 2 In the device shown, the processor 1001 can be used to call the control program of the radiant air conditioner stored in the memory 1002 and execute the relevant steps of the control method of the radiant air conditioner in the following embodiments.

[0058] This invention also provides a control method for a radiant air conditioner, which is applied to the aforementioned radiant air conditioner.

[0059] Reference Figure 3 This application proposes an embodiment of a control method for a radiant air conditioner. In this embodiment, the control method for the radiant air conditioner includes:

[0060] Step S10: Control the radiant air conditioner to operate in the first mode and obtain the temperature status parameters of the environment where the radiant air conditioner is located;

[0061] In this embodiment, the first mode is one of the cooling mode and the heating mode.

[0062] The environment here may include outdoor and / or indoor environments.

[0063] Temperature state parameters may include parameters characterizing the instantaneous temperature conditions of the environment and / or parameters characterizing the temperature conditions of the environment over a period of time. Temperature state parameters may include one or more temperature values ​​and / or one or more temperature change parameters (such as the direction of temperature change and / or the value of temperature change, etc.).

[0064] The temperature status parameters of a radiant air conditioner can be obtained by acquiring temperature sensors installed on the radiant air conditioner, sensors outside the radiant air conditioner, or meteorological data acquired via a network.

[0065] In the first mode, the temperature status parameters here can be obtained in real time or at preset intervals.

[0066] Step S20: When the temperature state parameter reaches the preset switching condition corresponding to the second mode, increment the count value;

[0067] The preset switching conditions are specifically the temperature status parameters that need to be met when the radiant air conditioner has the need to operate in the second mode.

[0068] Preset switching conditions may include the target quantity relationship, target size relationship and / or target value range of the temperature status parameters to be achieved.

[0069] The count value is specifically used to count the number of times the temperature status parameter reaches the preset switching condition in the first mode. Specifically, the count value can be initialized to a preset initial value when the first mode is started or the radiant air conditioner is turned on. In this embodiment, the preset initial value is 0. In other embodiments, the preset initial value can also be other non-zero values, such as 1, 3, etc. Increasing the count value specifically involves adding a preset value to the current count value. In this embodiment, the preset value is 1; in other embodiments, the preset value can also be a non-zero positive number such as 2, 3, etc. When the current count value is the preset initial value, the preset initial value is increased to obtain a new count value. When the current count value is the intermediate value after one or more increases from the preset initial value, this intermediate value can be increased to obtain a new count value.

[0070] Step S30: When the count value is less than the target value, return to step S10.

[0071] Step S40: When the count value is greater than or equal to the target value, control the radiant air conditioner to switch to the second mode of operation; wherein, the energy output by the radiant air conditioner is different in the first mode and the second mode.

[0072] The specific order in which steps S30 and S40 are executed is not limited.

[0073] The target value is the minimum count value that must be reached when the user confirms that they require the second mode of operation. For example, the target value could be 2, 3, etc.

[0074] The increased count value can be compared with the target value. If the count value is less than the target value, it indicates that the current switch to the second mode is likely not compatible with user comfort. In this case, return to the step of obtaining temperature status parameters and reconfirm whether the temperature status parameters meet the preset switching conditions. Continue until the count value is greater than or equal to the target value. This indicates that the target switch to the second mode is likely to match user comfort. At this point, switch the radiant air conditioner to the second mode. This helps ensure that the radiant air conditioner's mode switch matches the user's comfort needs, preventing large fluctuations in indoor temperature that could cause user discomfort, thereby effectively improving the user experience.

[0075] In one implementation of this embodiment, the first mode is a heating mode and the second mode is a cooling mode. In another implementation of this embodiment, the first mode is a cooling mode and the second mode is a heating mode.

[0076] It should be noted that the first mode and the second mode here can be the operating modes of the first heat pump system and / or the second heat pump system mentioned above.

[0077] This invention proposes a control method for a radiant air conditioner. During the operation of the radiant air conditioner in its first mode, the method acquires the temperature parameters of the outdoor environment. It counts the number of times the temperature parameters reach a preset switching condition corresponding to a second mode. The radiant air conditioner is switched to the second mode only when the count value is greater than or equal to a target value; otherwise, it continues to operate in the first mode. Based on this, it effectively avoids frequent switching between operating modes with different output energy, and effectively improves the accuracy of the radiant air conditioner's operating mode after switching. It also avoids large fluctuations in indoor temperature caused by slow temperature adjustment response of the radiant air conditioner, ensuring that the indoor temperature remains stable within the user's comfortable range, thus effectively improving indoor user comfort.

[0078] Furthermore, in this embodiment, the current user setting parameters of the preset function of the radiant air conditioner are obtained. When the user setting parameter is to enable the preset function, step S10 is executed, thereby ensuring that the radiant air conditioner can automatically switch operating modes according to user needs when the preset function is enabled. When the user setting parameter is to disable the preset function, the radiant air conditioner is controlled to maintain operation in the first mode, and the automatic switching of operating modes according to the steps mentioned above is stopped.

[0079] Furthermore, based on the above embodiments, another embodiment of the control method for a radiant air conditioner of this application is proposed. In this embodiment, obtaining the temperature state parameters of the environment where the radiant air conditioner is located includes: obtaining the temperature value and temperature change characteristic parameters of the outdoor environment where the radiant air conditioner is located, wherein the temperature state parameters include the temperature value and the characteristic parameters. Based on this, step S10 includes:

[0080] Step S11: Control the radiant air conditioner to operate in the first mode, and obtain the temperature value and temperature change characteristic parameters of the outdoor environment where the radiant air conditioner is located. The temperature status parameters include the temperature value and the characteristic parameters.

[0081] In this embodiment, the temperature value is specifically the current ambient temperature of the outdoor environment where the radiant air conditioner is located.

[0082] In this embodiment, the characteristic parameters of temperature change include the direction of temperature change and the value of temperature change. The direction of temperature change includes heating or cooling. The specific direction of temperature change can be determined based on the magnitude or sign of the difference between the current outdoor temperature value and the temperature value at a previous moment. The value of temperature change includes the amplitude of temperature change and / or the rate of temperature change, etc. In other embodiments, the characteristic parameters of temperature change may also include either the direction of temperature change or the value of temperature change.

[0083] Specifically, the temperature value and characteristic parameters can be determined based on the temperature sensor data on the outdoor system components of the radiant air conditioner, or based on the temperature sensor data located in the outdoor environment independently of the radiant air conditioner, or based on local weather data obtained through the network.

[0084] In this embodiment, the outdoor temperature value can accurately reflect the current heat exchange demand of the radiant air conditioning environment in the first mode, and the characteristic parameters of the outdoor temperature change can accurately reflect the change of the current heat exchange demand of the radiant air conditioning environment in the first mode. Therefore, by combining the outdoor temperature value and the characteristic parameters of the temperature change of the radiant air conditioning environment, the demand for switching to the second mode during the operation of the radiant air conditioning in the first mode can be accurately reflected. This is conducive to further improving the accuracy of the radiant air conditioning operation mode switching, thereby improving the comfort of indoor users after the mode switch.

[0085] In other embodiments, one of the temperature values ​​and the characteristic parameters of temperature change may also be used as the temperature state parameter.

[0086] Furthermore, in one implementation of this embodiment, the characteristic parameters include the direction of temperature change and the value of temperature change, the first mode is a heating mode, and the second mode is a cooling mode, as shown in the reference. Figure 4 After step S11, the following steps are also included:

[0087] Step S12: When the temperature value is greater than or equal to the first preset temperature, the temperature change direction is heating, and the temperature change value is greater than or equal to the first preset amplitude, it is determined that the temperature state parameter has reached the preset switching condition.

[0088] In this embodiment, the first preset temperature can be a value in the range [25℃, 28℃]. For example, 25℃, 26℃, 27℃, 28℃, etc.

[0089] The first preset amplitude can be a value in the range [1℃, 5℃]. For example, 1℃, 2℃, 3℃, 4℃, etc.

[0090] When a radiant air conditioner is operating in heating mode, if the detected outdoor ambient temperature is high and the temperature rise is excessive, it indicates that continuing to operate in heating mode will lead to a high indoor temperature and cause user discomfort. The radiant air conditioner needs to switch to cooling mode under the current conditions. At this point, the temperature parameters are determined to meet the preset switching conditions. The number of times the radiant air conditioner needs to switch to cooling mode, represented by a counter value, is accumulated. Only when the counter value reaches the target value is the radiant air conditioner switched from heating mode to cooling mode. This improves the accuracy of the radiant air conditioner's switch from heating to cooling mode, avoids erroneous switching from heating mode to cooling mode during operation, and effectively improves indoor user comfort.

[0091] In other embodiments, the temperature value and temperature change value can be substituted into a preset formula to calculate the magnitude of the demand for switching to the cooling mode. When the magnitude value is greater than a preset threshold, it is determined that the temperature state parameter has reached the preset switching condition; when the magnitude value is less than or equal to the preset threshold, it is determined that the temperature state parameter has not reached the preset switching condition.

[0092] Furthermore, in this embodiment, after step S11, the method further includes: when the temperature value is less than the second preset temperature, or when the temperature value is greater than or equal to the first preset temperature, the temperature change direction is cooling, and the temperature change value is greater than or equal to the second preset amplitude, the count value is reduced and the method returns to the step of obtaining the temperature value and temperature change characteristic parameters of the outdoor environment where the radiant air conditioner is located; wherein, the first preset temperature is greater than the second preset temperature.

[0093] In this embodiment, a preset initial value is set as the count value, which is less than the target value. Specifically, the preset initial value can be 0 or other values ​​greater than 0. In other embodiments, the count value can be reduced by a preset adjustment value to obtain a new count value, and then the process can return to the step of obtaining the temperature value and temperature change characteristic parameters of the outdoor environment where the radiant air conditioner is located.

[0094] In this embodiment, the second preset temperature can be a value in the range [18℃, 24℃]. For example, 18℃, 20℃, 22℃, 24℃, etc.

[0095] The second preset amplitude can be a value in the range [1℃, 5℃]. For example, 1℃, 2℃, 3℃, 4℃, etc.

[0096] Specifically, when the temperature value is greater than or equal to the second preset temperature and less than the first preset temperature, or when the temperature value is greater than or equal to the first preset temperature, the direction of temperature change is cooling and the temperature change value is less than the second preset amplitude, or when the temperature value is greater than or equal to the first preset temperature, the direction of temperature change is heating and the temperature change value is less than the first preset amplitude, the current count value can be maintained unchanged and the process can return to the step of obtaining the temperature value and temperature change characteristic parameters of the outdoor environment where the radiant air conditioner is located.

[0097] A temperature value lower than the second preset temperature indicates that the outdoor ambient temperature is low, and the indoor environment still requires heating, so there is no need to switch to cooling mode. A temperature value greater than or equal to the first preset temperature, with the temperature changing in a cooling direction and the temperature change value greater than or equal to the second preset amplitude, indicates that the outdoor temperature is high but has a cooling trend. Switching to cooling mode would easily match the indoor user's comfort needs after cooling, so it can be considered that the indoor environment still requires heating, and there is no need to switch to cooling mode. In both cases, the count value is initialized, and the need to switch to cooling mode is re-detected. This further ensures that the radiant air conditioner does not mistakenly switch to cooling mode, further improving the accuracy of switching from heating mode to cooling mode and enhancing the comfort of indoor users.

[0098] Furthermore, in another implementation of this embodiment, the characteristic parameters include the direction of temperature change and the value of temperature change, the first mode is a cooling mode, and the second mode is a heating mode, as shown in the reference. Figure 5 After step S11, the following steps are also included:

[0099] Step S13: When the temperature value is less than or equal to the third preset temperature, the temperature change direction is cooling, and the temperature change value is greater than or equal to the third preset amplitude, it is determined that the temperature state parameter has reached the preset switching condition.

[0100] Here, the third preset temperature is lower than the first preset temperature mentioned above. In this embodiment, the third preset temperature can be a value in the range [20℃, 23℃]. For example, 20℃, 21℃, 22℃, 23℃, etc.

[0101] The third preset amplitude can be a value in the range [1℃, 5℃]. For example, 1℃, 2℃, 3℃, 4℃, etc.

[0102] When a radiant air conditioner is operating in cooling mode, if the detected outdoor ambient temperature is too low and the temperature drop is too large, it indicates that continuing to operate in cooling mode will lead to excessively low indoor temperatures and user discomfort. The radiant air conditioner needs to switch to heating mode under the current conditions. At this point, the temperature parameters are determined to meet the preset switching conditions. The number of times the radiant air conditioner needs to switch to heating mode, represented by a counter value, is accumulated. Only when the counter value reaches the target value is the radiant air conditioner switched from cooling mode to heating mode. This improves the accuracy of the radiant air conditioner's switch from cooling to heating mode and avoids erroneous switching during operation, thereby effectively improving indoor user comfort.

[0103] Furthermore, in this embodiment, after step S11, the method further includes: when the temperature value is greater than the fourth preset temperature, or when the temperature value is less than or equal to the third preset temperature, the temperature change direction is upward, and the temperature change value is greater than or equal to the fourth preset amplitude, the count value is reduced and the method returns to the step of obtaining the temperature value and temperature change characteristic parameters of the outdoor environment where the radiant air conditioner is located; wherein, the preset initial value is less than the target value, and the fourth preset temperature is greater than the third preset temperature.

[0104] In this embodiment, a preset initial value is set as the count value, which is less than the target value. Specifically, the preset initial value can be 0 or other values ​​greater than 0. In other embodiments, the count value can be reduced by a preset adjustment value to obtain a new count value, and then the process can return to the step of obtaining the temperature value and temperature change characteristic parameters of the outdoor environment where the radiant air conditioner is located.

[0105] In this embodiment, the fourth preset temperature can be a value in the range [24℃, 28℃]. For example, 24℃, 25℃, 27℃, 28℃, etc.

[0106] The fourth preset amplitude can be a value in the range [1℃, 5℃]. For example, 1℃, 2℃, 3℃, 4℃, etc.

[0107] Specifically, when the temperature value is less than or equal to the fourth preset temperature and greater than the third preset temperature, or when the temperature value is less than or equal to the third preset temperature, the direction of temperature change is cooling and the temperature change value is less than the third preset amplitude, or when the temperature value is less than or equal to the third preset temperature, the direction of temperature change is heating and the temperature change value is less than the fourth preset amplitude, the current count value can be maintained unchanged and the process can return to the step of obtaining the temperature value and temperature change characteristic parameters of the outdoor environment where the radiant air conditioner is located.

[0108] A temperature value greater than the fourth preset temperature indicates that the outdoor ambient temperature is high. In this case, there is still a need for cooling indoors, and there is no need to switch to heating mode. When the temperature value is less than or equal to the third preset temperature, the temperature change direction is upward, and the temperature change value is greater than or equal to the fourth preset amplitude, it indicates that the outdoor temperature is low but has a rising trend. Switching to heating mode would easily match the indoor user's comfort needs after the temperature rise. Therefore, it can be considered that there is still a need for cooling indoors, and there is no need to switch to heating mode. In both cases, the count value is initialized and the need to switch to heating mode is re-detected. This further ensures that the radiant air conditioner does not switch to heating mode incorrectly, further improving the accuracy of switching from cooling mode to heating mode and improving the comfort of indoor users.

[0109] Furthermore, based on any of the above embodiments, another embodiment of the control method for radiant air conditioning of this application is proposed. In this embodiment, reference is made to... Figure 6 Following S40, the following is also included:

[0110] Step S50: Obtain the current set temperature of the indoor space regulated by the radiant air conditioner, and obtain the reference value of the set temperature corresponding to the second mode;

[0111] The set temperature is specifically the target value that the current indoor room temperature needs to be achieved for the operation and control of the radiant air conditioner. Specifically, the set temperature is the temperature value currently stored in the corresponding storage area of ​​the memory.

[0112] The reference value is specifically the target room temperature value used for regulating the operation of the radiant air conditioner in the pre-set second mode. Different second modes correspond to different reference values. The reference value for the heating mode is lower than that for the cooling mode.

[0113] Step S60: Determine the target temperature of the indoor space based on the set temperature and the reference value. The target temperature is the target value that the room temperature of the indoor space needs to reach when the radiant air conditioner is running.

[0114] Different set temperatures and different reference values ​​correspond to different target temperatures.

[0115] In one implementation of this embodiment, when the first mode is a heating mode and the second mode is a cooling mode, if the set temperature is less than the reference value, then the reference value is determined to be the target temperature; if the set temperature is greater than or equal to the reference value, then the set temperature is determined to be the target temperature. Based on this, it is beneficial to ensure that after the radiant air conditioner switches from heating mode to cooling mode, the user does not need to readjust the set temperature of the indoor space, simplifying user operation while ensuring that the target temperature used for temperature control by the radiant air conditioner after switching to cooling mode is not too low, ensuring that the indoor temperature can be maintained within the user's comfort range before and after the mode switch, further improving indoor user comfort.

[0116] In another implementation of this embodiment, when the first mode is cooling mode and the second mode is heating mode, if the set temperature is greater than the reference value, then the reference value is determined to be the target temperature; if the set temperature is less than or equal to the reference value, then the set temperature is determined to be the target temperature. Based on this, it is beneficial to ensure that after the radiant air conditioner switches from cooling mode to heating mode, the user does not need to readjust the set temperature of the indoor space, simplifying user operation while ensuring that the target temperature used for temperature control by the radiant air conditioner after switching to heating mode is not too high, ensuring that the indoor temperature can be maintained within the user's comfort range before and after the mode switch, further improving indoor user comfort.

[0117] In another implementation of this embodiment, the average of the reference value and the set temperature can also be used as the target temperature. Alternatively, the weight values ​​corresponding to the reference value and the set temperature can be determined according to the second mode, and the target temperature can be calculated by weighted averaging the reference value and the set temperature according to the determined weight values. The weight values ​​corresponding to the reference value and the set temperature are different depending on the second mode.

[0118] When there is more than one indoor space, different indoor spaces correspond to different set temperatures, and different set temperatures and reference values ​​can correspond to different target temperatures.

[0119] Step S70: Control the operation of the radiant air conditioner according to the target temperature.

[0120] Specifically, the operation of the radiant air conditioning system is controlled to achieve the target temperature in the indoor space.

[0121] In this embodiment, the above method can ensure that after switching from the first mode to the second mode, the set temperature of the radiant air conditioner in the original first mode can be adjusted in a timely and accurate manner to the target temperature that meets the user's comfort needs, thereby regulating the operation of the radiant air conditioner and further ensuring that the indoor temperature is not too high or too low, and can be stably maintained within the user's comfort range, thereby further improving the indoor user comfort after the radiant air conditioner mode is switched.

[0122] Furthermore, this embodiment of the invention also proposes a storage medium storing a control program for a radiant air conditioner. When the control program for the radiant air conditioner is executed by a processor, it implements the relevant steps of any embodiment of the control method for the radiant air conditioner described above.
