Description

Technical Field

[0001] This application relates to the technical field of smart homes, for example, to a method, device, and radiant air conditioner for controlling a radiant air conditioner. Background Art

[0002] With the improvement of people's requirements for the quality of life and the increasing attention to energy utilization efficiency, the intelligence and precision of temperature control systems have become an important development trend. Currently, most temperature control methods on the market adopt the method of closing the valve when the temperature is reached. This control method has not only been widely used but also meets the basic temperature control requirements to a certain extent.

[0003] At the present stage, a method of closing the valve when the temperature is reached is disclosed in the related art, including: when the ambient temperature is monitored by a sensor and reaches the target temperature set by the user, the control system will immediately issue an instruction to close the valve of the heating or cooling device that is running. However, due to the inertia of temperature change, the ambient temperature will not immediately stop changing after the valve is closed, but will continue to change in the previous heating or cooling trend for a period of time until it reaches a maximum dead band point, and then begins to change in the opposite direction. Taking cooling as an example, when the temperature drops to the set value and the valve of the cooling device is closed, the temperature will continue to drop a certain distance to reach the maximum dead band, and then gradually rise; when the temperature reaches the set value again, the valve of the cooling device is reopened, and the temperature will rise slightly and then drop, and so on in a cycle.

[0004] It can be seen that the temperature control accuracy of the related art is not high, and the actual temperature change range often exceeds the upper and lower limits set by the user, resulting in large fluctuations in the ambient temperature and affecting the comfort of the user. Moreover, since the temperature will continue to change in the current trend for a period of time after the valve is closed, it is easy to cause a certain degree of overcooling or overheating, which not only wastes energy but also may cause unnecessary damage to the equipment. Therefore, how to effectively improve the temperature control accuracy and comfort, while reducing energy waste, has become an urgent problem to be solved in the current temperature control technology field.

[0035] In the embodiments of the present disclosure, an intelligent household appliance device refers to a household appliance product formed by introducing microprocessor, sensor technology, and network communication technology into household appliance devices, and has the characteristics of intelligent control, intelligent perception, and intelligent application. The operation process of intelligent household appliance devices often depends on the application and processing of modern technologies such as the Internet of Things, the Internet, and electronic chips. For example, an intelligent household appliance device can be connected to an electronic device to realize remote control and management of the intelligent household appliance device by the user.

[0036] In the embodiments of the present disclosure, a terminal device refers to an electronic device with a wireless connection function.

[0037] Figure 1 is a schematic diagram of a method for controlling a radiant air conditioner provided by an embodiment of the present disclosure; in combination with Figure 1 As shown, optionally, an embodiment of the present disclosure provides a method for controlling a radiant air conditioner, including:

[0038] S11, the radiant air conditioner obtains the set temperature of the radiant air conditioner, the initial temperature fluctuation value, and the current opening and closing state of the valve.

[0039] S12, the radiant air conditioner determines the corrected set temperature fluctuation value according to the set temperature of the radiant air conditioner, the initial temperature fluctuation value, and the current opening and closing state of the valve.

[0040] S13, the radiant air conditioner controls the valve according to the corrected set temperature fluctuation value and the set temperature.

[0041] In this solution, a valve is provided between the radiant air conditioner and the pipeline system. This valve is used to adjust the refrigerant or heat medium flow rate passing through the radiant air conditioner, thereby controlling the indoor temperature. Specifically, the radiant air conditioner can obtain the preset temperature and the initial temperature fluctuation value stored in advance. For example, the preset temperature stored in advance can be 26°C, and the initial temperature fluctuation value can be 1°C. At the same time, the radiant air conditioner can also detect and record the current opening and closing state of the valve in real time. With this solution, by obtaining the preset temperature, the initial temperature fluctuation value, and the current opening and closing state of the valve of the radiant air conditioner, basic data is provided for subsequent precise control, thereby realizing the optimized control of the radiant air conditioner system.

[0042] Further, taking the heating mode as an example, the radiant air conditioner determines the corrected set temperature fluctuation value according to the set temperature of the radiant air conditioner, the initial temperature fluctuation value, and the current opening and closing state of the valve, which may include: when the current opening and closing state of the valve is open, the radiant air conditioner controls the radiant air conditioner to close the valve according to the set temperature of the radiant air conditioner and the initial temperature fluctuation value. After the radiant air conditioner closes the valve, the radiant air conditioner determines the peak indoor temperature after closing the valve. The radiant air conditioner determines the corrected set temperature fluctuation value according to the peak indoor temperature after closing the valve, the set temperature of the radiant air conditioner, and the initial temperature fluctuation value. In another example, the radiant air conditioner determines the corrected set temperature fluctuation value according to the set temperature of the radiant air conditioner, the initial temperature fluctuation value, and the current opening and closing state of the valve, which may include: when the current opening and closing state of the valve is closed, the radiant air conditioner controls the radiant air conditioner to open the valve according to the set temperature of the radiant air conditioner and the initial temperature fluctuation value. After the radiant air conditioner opens the valve, the radiant air conditioner determines the valley indoor temperature after opening the valve. The radiant air conditioner determines the corrected set temperature fluctuation value according to the valley indoor temperature after opening the valve, the set temperature of the radiant air conditioner, and the initial temperature fluctuation value.

[0043] Further, after the radiant air conditioner determines the corrected set temperature fluctuation value, it can control the valve in combination with the corrected set temperature fluctuation value and the set temperature. Specifically, the radiant air conditioner determines a set temperature range according to the corrected fluctuation value. When the indoor temperature reaches the upper and lower limits of this range, the valve will automatically open and close to adjust the cold and hot water flow rate to ensure that the indoor temperature is always stable within the comfortable range. For example, the corrected temperature fluctuation value is 0.5°C. The set temperature is 26°C, then the set temperature range can be determined to be 25.5°C to 26.5°C based on the corrected set temperature fluctuation value. In this way, the valve is precisely opened and closed when the indoor temperature reaches 25.5°C or 26.5°C.

[0044] By adopting the method for controlling a radiation air conditioner provided by the embodiments of the present disclosure, by obtaining the set temperature of the radiation air conditioner, the initial temperature fluctuation value, and the current opening and closing state of the valve, the corrected set temperature fluctuation value can be accurately determined, and the valve can be accurately controlled accordingly. With this solution, the phenomenon of excessive cooling or heating caused by temperature inertia can be effectively avoided, thereby significantly improving the accuracy and comfort of temperature control, reducing energy waste, extending the service life of the equipment, and meeting people's needs for high-quality life and efficient energy utilization.

[0045] Figure 2 It is a schematic diagram of a method for determining the corrected set temperature fluctuation value provided by the embodiments of the present disclosure; in combination with Figure 2 As shown, optionally, in S12, the radiation air conditioner determines the corrected set temperature fluctuation value according to the set temperature of the radiation air conditioner, the initial temperature fluctuation value, and the current opening and closing state of the valve, including:

[0046] In S21, when the current opening and closing state of the valve is open, the radiation air conditioner controls the radiation air conditioner to close the valve according to the set temperature of the radiation air conditioner and the initial temperature fluctuation value.

[0047] In S22, after the radiation air conditioner closes the valve, the radiation air conditioner determines the peak indoor temperature after the valve is closed.

[0048] In S23, the radiation air conditioner determines the corrected set temperature fluctuation value according to the peak indoor temperature after the valve is closed, the set temperature of the radiation air conditioner, and the initial temperature fluctuation value.

[0049] In this solution, when it is detected that the current opening and closing state of the valve is the open state, the radiation air conditioner can control the radiation air conditioner to close the valve according to the set temperature of the radiation air conditioner and the initial temperature fluctuation value. For example, if the set temperature of the radiation air conditioner is 25 °C and the initial temperature fluctuation value is 1 °C, then the set temperature range can be determined to be 24 °C to 26 °C accordingly. In this way, the radiation air conditioner can be controlled to close the valve when the indoor temperature reaches 24 °C to 26 °C. With this solution, the valve can be closed according to the preset system parameters.

[0050] Furthermore, after the radiation air conditioner closes the valve, the radiation air conditioner determines the peak indoor temperature after the valve is closed. Specifically, after the radiation air conditioner closes the valve, the radiation air conditioner periodically obtains the indoor temperature value. The radiation air conditioner compares the indoor temperature value obtained in the previous cycle with the indoor temperature value obtained in the current cycle until the peak indoor temperature after the valve is closed is screened out. With this solution, it can be ensured that the highest indoor temperature point after the valve is closed is accurately captured, providing reliable data support for the subsequent correction of the set temperature fluctuation value and valve control.

[0051] Further, the radiant air conditioner can determine a corrected set temperature fluctuation value based on the indoor temperature peak value after valve closure, the set temperature of the radiant air conditioner, and the initial temperature fluctuation value. Specifically, the radiant air conditioner calculates the sum of the set temperature of the radiant air conditioner and the initial temperature fluctuation value to obtain a first fluctuation temperature value. The radiant air conditioner compares the indoor temperature peak value after valve closure with the first fluctuation temperature value to obtain a first comparison result. The radiant air conditioner compares the indoor temperature peak value after valve closure with the set temperature of the radiant air conditioner to obtain a second comparison result. The radiant air conditioner determines the corrected set temperature fluctuation value according to the first comparison result or the second comparison result. With this solution, by continuously monitoring the indoor temperature change, the temperature peak value after valve closure is accurately determined, and further combined with the set temperature and the initial fluctuation value, the corrected temperature fluctuation value is calculated. This process not only improves the accuracy and stability of temperature control, but also optimizes the operation efficiency of the radiant air conditioner system and reduces energy waste.

[0052] Figure 3 is a schematic diagram of a method provided by an embodiment of the present disclosure for determining the indoor temperature peak value after valve closure; combined Figure 3 As shown, optionally, S22. After the radiant air conditioner closes the valve, the radiant air conditioner determines the indoor temperature peak value after valve closure, including:

[0053] S31. After the radiant air conditioner closes the valve, the radiant air conditioner periodically obtains the indoor temperature value.

[0054] S32. The radiant air conditioner compares the indoor temperature value obtained in the previous cycle with the indoor temperature value obtained in the current cycle until the indoor temperature peak value after valve closure is screened out.

[0055] In this solution, after the radiant air conditioner closes the valve, it enters the temperature peak monitoring stage. The radiant air conditioner can use the ambient temperature sensor to periodically obtain the indoor temperature value at a fixed time interval. For example, the fixed time interval can be 10 seconds. Specifically, after each temperature value is obtained, the temperature value of the current cycle can be compared with the temperature value of the previous cycle. If the temperature value of the current cycle is higher than the temperature value of the previous cycle, the current value is temporarily stored as a candidate peak value; if the temperature value of the current cycle is lower than or equal to the temperature value of the previous cycle, it is determined that the temperature has reached the peak and begins to decline. At this time, the radiant air conditioner can confirm the highest temperature value temporarily stored before as the indoor temperature peak value after valve closure and end the peak screening process. This process ensures that the highest point of the indoor temperature after valve closure can be accurately captured through cycle-by-cycle temperature comparison, providing accurate data support for subsequent temperature fluctuation correction and control strategies.

[0056] Optionally, S23. The radiant air conditioner determines the corrected set temperature fluctuation value according to the indoor temperature peak value after valve closure, the set temperature of the radiant air conditioner, and the initial temperature fluctuation value, including:

[0057] The radiant air conditioner calculates the sum of the set temperature of the radiant air conditioner and the initial temperature fluctuation value to obtain a first fluctuation temperature value.

[0058] The radiant air conditioner compares the indoor temperature peak value after valve closing with the first fluctuation temperature value to obtain a first comparison result.

[0059] The radiant air conditioner compares the indoor temperature peak value after valve closing with the set temperature of the radiant air conditioner to obtain a second comparison result.

[0060] The radiant air conditioner determines a corrected set temperature fluctuation value according to the first comparison result or the second comparison result.

[0061] In this solution, the radiant air conditioner can calculate the sum of the set temperature of the radiant air conditioner and the initial temperature fluctuation value as the first fluctuation temperature value. For example, if the set temperature of the radiant air conditioner is 26 °C and the initial temperature fluctuation value is 0.6 °C, then the radiant air conditioner can calculate the first fluctuation temperature value as 26.6 °C. In this way, the first fluctuation temperature value can be obtained more accurately.

[0062] Furthermore, the radiant air conditioner compares the indoor temperature peak value after valve closing with the first fluctuation temperature value to obtain a first comparison result. Among them, the first comparison result is that the indoor temperature peak value after valve closing is greater than the first fluctuation temperature value or the indoor temperature peak value after valve closing is less than the first fluctuation temperature value.

[0063] Similarly, the radiant air conditioner compares the indoor temperature peak value after valve closing with the set temperature of the radiant air conditioner to obtain a second comparison result. Here, the second comparison result includes: the indoor temperature peak value after valve closing is greater than the set temperature of the radiant air conditioner, or the indoor temperature peak value after valve closing is less than the set temperature of the radiant air conditioner.

[0064] Furthermore, the radiant air conditioner determines a corrected set temperature fluctuation value according to the first comparison result, including: when the first comparison result is that the indoor temperature peak value after valve closing is less than the first fluctuation temperature value, determining the corrected set temperature fluctuation value as the sum of the initial temperature fluctuation value and the first correction value; when the first comparison result is that the indoor temperature peak value after valve closing is greater than the first fluctuation temperature value, determining the corrected set temperature fluctuation value as the sum of the initial temperature fluctuation value and the second correction value. With this solution, the corrected set temperature fluctuation value can be accurately determined in combination with the first comparison result.

[0065] Optionally, the first correction value is determined by the following method:

[0066] When the difference between the set temperature of the radiant air conditioner and the peak indoor temperature after valve closing is less than or equal to the first temperature threshold, the first correction value is determined to be a1; when the difference between the set temperature of the radiant air conditioner and the peak indoor temperature after valve closing is greater than the first temperature threshold and less than or equal to the second temperature threshold, the first correction value is determined to be a2; when the difference between the set temperature of the radiant air conditioner and the peak indoor temperature after valve closing is greater than the second temperature threshold and less than or equal to the third temperature threshold, the first correction value is determined to be a3. Among them, a1 < a2 < a3, and the first temperature threshold < the second temperature threshold < the third temperature threshold. As an example, a1 is 0.1, a2 is 0.2, a3 is 0.3, the first temperature threshold is 0.1, the second temperature threshold is 0.2, and the third temperature threshold is 0.3. In this embodiment, according to this rule, the first correction value can also be determined in turn according to the temperature range where the difference between the set temperature of different radiant air conditioners and the peak indoor temperature after valve closing is located. It should be noted that the maximum value of the first correction value is the initial temperature fluctuation value. With this solution, the first correction value can be accurately obtained.

[0067] Optionally, the second correction value is determined by the following method:

[0068] When the peak indoor temperature after valve closing is greater than the sum of the first fluctuation temperature value and 0.1, the second correction value is determined to be the initial temperature fluctuation value.

[0069] When the peak indoor temperature after valve closing is greater than the sum of the first fluctuation temperature value and 0.2, the second correction value is determined to be the sum of the initial temperature fluctuation value and 0.1.

[0070] When the peak indoor temperature after valve closing is greater than the sum of the first fluctuation temperature value and 0.3, the second correction value is determined to be the sum of the initial temperature fluctuation value and 0.2. With this solution, the second correction value can be accurately obtained.

[0071] Optionally, the radiant air conditioner determines the corrected set temperature fluctuation value according to the second comparison result, including:

[0072] When the second comparison result is that the peak indoor temperature after valve closing is less than the set temperature of the radiant air conditioner, the corrected set temperature fluctuation value is determined to be the difference between the initial temperature fluctuation value and the third correction value. With this solution, the corrected set temperature fluctuation value can be accurately determined in combination with the second comparison result.

[0073] Optionally, the third correction value is determined by the following method:

[0074] When the difference between the set temperature of the radiant air conditioner and the peak indoor temperature after valve closing is less than or equal to the first temperature threshold, the third correction value is determined to be a1.

[0075] When the difference between the set temperature of the radiant air conditioner and the peak indoor temperature after the valve is closed is greater than the first temperature threshold and less than or equal to the second temperature threshold, determine the third correction value as a2.

[0076] When the difference between the set temperature of the radiant air conditioner and the peak indoor temperature after the valve is closed is greater than the second temperature threshold and less than or equal to the third temperature threshold, determine the third correction value as a3. Wherein, a1 < a2 < a3, the first temperature threshold < the second temperature threshold < the third temperature threshold. As an example, a1 is 0.1, a2 is 0.2, a3 is 0.3, the first temperature threshold is 0.1, the second temperature threshold is 0.2, and the third temperature threshold is 0.3. With this scheme, the third correction value can be accurately determined.

[0077] In an optimized scheme, in order to more precisely determine the corrected set temperature fluctuation value for the next cycle, the first correction value, the second correction value, or the third correction value can be divided by 2 respectively in the calculation process of the corrected set temperature fluctuation value in the previous cycle, so as to be used as the first correction value, the second correction value, or the third correction value for the next cycle, which is convenient for providing strong data for the correction of the set temperature fluctuation value in the next cycle.

[0078] Figure 4 It is another schematic diagram of a method for determining the corrected set temperature fluctuation value provided by the embodiments of the present disclosure; in combination with Figure 4 As shown, optionally, S12, the radiant air conditioner determines the corrected set temperature fluctuation value according to the set temperature of the radiant air conditioner, the initial temperature fluctuation value, and the current opening and closing state of the valve, including:

[0079] S41, when the current opening and closing state of the valve is closed, the radiant air conditioner controls the valve of the radiant air conditioner to open according to the set temperature of the radiant air conditioner and the initial temperature fluctuation value.

[0080] S42, after the radiant air conditioner opens the valve, the radiant air conditioner determines the valley value of the indoor temperature after the valve is opened.

[0081] S43, the radiant air conditioner determines the corrected set temperature fluctuation value according to the valley value of the indoor temperature after the valve is opened, the set temperature of the radiant air conditioner, and the initial temperature fluctuation value.

[0082] In this scheme, when it is detected that the current opening and closing state of the valve is the closed state, the radiant air conditioner can control the valve of the radiant air conditioner to open according to the set temperature of the radiant air conditioner and the initial temperature fluctuation value. For example, if the set temperature of the radiant air conditioner is 25 °C and the initial temperature fluctuation value is 1 °C, then the set temperature range can be determined to be 24 °C to 26 °C accordingly. In this way, the valve of the radiant air conditioner can be controlled to open when the indoor temperature reaches 24 °C to 26 °C. With this scheme, the valve can be opened according to the pre-set system parameters.

[0083] Further, after the radiation air conditioner opens the valve, the radiation air conditioner determines the minimum indoor temperature value after the valve is opened. Specifically, after the radiation air conditioner opens the valve, the radiation air conditioner periodically obtains the indoor temperature value. The radiation air conditioner compares the indoor temperature value obtained in the previous cycle with the indoor temperature value obtained in the current cycle until the minimum indoor temperature value after the valve is opened is selected. With this solution, it is possible to ensure accurate capture of the lowest indoor temperature after the valve is opened, providing reliable data support for the subsequent correction of the set temperature fluctuation value and valve control.

[0084] Further, the radiation air conditioner can determine the corrected set temperature fluctuation value according to the minimum indoor temperature value after the valve is opened, the set temperature of the radiation air conditioner, and the initial temperature fluctuation value. Specifically, the radiation air conditioner calculates the difference between the set temperature of the radiation air conditioner and the initial temperature fluctuation value to obtain the second fluctuation temperature value. The radiation air conditioner compares the minimum indoor temperature value after the valve is opened with the second fluctuation temperature value to obtain a third comparison result. The radiation air conditioner compares the minimum indoor temperature value after the valve is opened with the set temperature of the radiation air conditioner to obtain a fourth comparison result. The radiation air conditioner determines the corrected set temperature fluctuation value according to the third comparison result or the fourth comparison result. With this solution, by continuously monitoring the change of the indoor temperature, accurately determining the minimum temperature value after the valve is opened, and further calculating the corrected temperature fluctuation value in combination with the set temperature and the initial fluctuation value. This process not only improves the accuracy and stability of temperature control, but also optimizes the operation efficiency of the radiation air conditioner system and reduces energy waste.

[0085] Figure 5 is a schematic diagram of a method provided by an embodiment of the present disclosure for determining the minimum indoor temperature value after the valve is opened; in combination with Figure 5 As shown, optionally, S42, after the radiation air conditioner opens the valve, the radiation air conditioner determines the minimum indoor temperature value after the valve is opened, including:

[0086] S51, after the radiation air conditioner opens the valve, the radiation air conditioner periodically obtains the indoor temperature value.

[0087] S52, the radiation air conditioner compares the indoor temperature value obtained in the previous cycle with the indoor temperature value obtained in the current cycle until the minimum indoor temperature value after the valve is opened is selected.

[0088] In this solution, after the radiation air conditioner opens the valve, it enters the temperature trough monitoring stage. The radiation air conditioner can use the ambient temperature sensor to periodically obtain the indoor temperature value at fixed time intervals. For example, the fixed time interval can be 10 seconds. Specifically, after each temperature value is obtained, the temperature value of the current cycle can be compared with the temperature value of the previous cycle. If the temperature value of the current cycle is lower than the temperature value of the previous cycle, the current value is temporarily stored as a candidate trough value; if the temperature value of the current cycle is higher than or equal to the temperature value of the previous cycle, it is determined that the temperature has reached the trough and starts to rise. At this time, the radiation air conditioner can confirm the lowest temperature value temporarily stored before as the indoor temperature trough value after the valve is opened, and end the trough screening process. This process ensures that the lowest point of the indoor temperature after the valve is closed can be accurately captured through cycle-by-cycle temperature comparison, providing accurate data support for subsequent temperature fluctuation correction and control strategies.

[0089] Optionally, in S43, the radiation air conditioner determines the corrected set temperature fluctuation value according to the indoor temperature trough value after the valve is opened, the set temperature of the radiation air conditioner, and the initial temperature fluctuation value, including:

[0090] The radiation air conditioner calculates the difference between the set temperature of the radiation air conditioner and the initial temperature fluctuation value to obtain the second fluctuation temperature value.

[0091] The radiation air conditioner compares the indoor temperature trough value after the valve is opened with the second fluctuation temperature value to obtain the third comparison result.

[0092] The radiation air conditioner compares the indoor temperature trough value after the valve is opened with the set temperature of the radiation air conditioner to obtain the fourth comparison result.

[0093] The radiation air conditioner determines the corrected set temperature fluctuation value according to the third comparison result or the fourth comparison result.

[0094] In this solution, the radiation air conditioner can calculate the difference between the set temperature of the radiation air conditioner and the initial temperature fluctuation value as the second fluctuation temperature value. For example, if the set temperature of the radiation air conditioner is 26°C and the initial temperature fluctuation value is 0.6°C, the radiation air conditioner can calculate the second fluctuation temperature value as 25.4°C. In this way, the second fluctuation temperature value can be obtained more accurately.

[0095] Further, the radiation air conditioner compares the indoor temperature trough value after the valve is opened with the second fluctuation temperature value to obtain the third comparison result. Among them, the third comparison result is that the indoor temperature trough value after the valve is opened is greater than the second fluctuation temperature value or the indoor temperature trough value after the valve is opened is less than the second fluctuation temperature value.

[0096] Similarly, the radiant air conditioner compares the valley value of the indoor temperature after the valve is opened with the set temperature of the radiant air conditioner to obtain a fourth comparison result. Here, the fourth comparison result is that the valley value of the indoor temperature after the valve is opened is greater than the set temperature of the radiant air conditioner, or the valley value of the indoor temperature after the valve is opened is less than the set temperature of the radiant air conditioner.

[0097] Furthermore, the radiant air conditioner determines a corrected set temperature fluctuation value according to the third comparison result, including:

[0098] When the third comparison result is that the valley value of the indoor temperature after the valve is opened is less than the second fluctuation temperature value, it is determined that the corrected set temperature fluctuation value is the sum of the initial temperature fluctuation value and the fourth correction value.

[0099] When the third comparison result is that the valley value of the indoor temperature after the valve is opened is greater than the second fluctuation temperature value and less than or equal to the set temperature of the radiant air conditioner, it is determined that the corrected set temperature fluctuation value is the sum of the initial temperature fluctuation value and the fifth correction value.

[0100] Optionally, the fourth correction value is determined by the following method:

[0101] If the valley value of the indoor temperature after the valve is opened is less than or equal to the difference between the second fluctuation temperature value and a1, the fourth correction value is determined to be a1.

[0102] If the valley value of the indoor temperature after the valve is opened is less than or equal to the difference between the second fluctuation temperature value and a2, the fourth correction value is determined to be a2.

[0103] If the valley value of the indoor temperature after the valve is opened is less than or equal to the difference between the second fluctuation temperature value and a3, the fourth correction value is determined to be a3.

[0104] Wherein, a1 < a2 < a3. As an example, a1 is 0.1, a2 is 0.2, and a3 is 0.3. With this scheme, the fourth correction value can be accurately determined.

[0105] Optionally, the fifth correction value is determined by the following method:

[0106] If the difference between the set temperature of the radiant air conditioner and the valley value of the indoor temperature after the valve is opened is less than or equal to a1, the fifth correction value is determined to be a1.

[0107] If the difference between the set temperature of the radiant air conditioner and the valley value of the indoor temperature after the valve is opened is less than or equal to a2, the fifth correction value is determined to be a2.

[0108] If the difference between the set temperature of the radiant air conditioner and the valley value of the indoor temperature after the valve is opened is less than or equal to a3, the fifth correction value is determined to be a3. Wherein, a1 < a2 < a3. As an example, a1 is 0.1, a2 is 0.2, and a3 is 0.3. With this scheme, the fifth correction value can be accurately determined.

[0109] Optionally, the radiant air conditioner determines a corrected set temperature fluctuation value according to the fourth comparison result, including:

[0110] If the indoor temperature trough value after the valve is opened is greater than the set temperature of the radiant air conditioner, it is determined that the corrected set temperature fluctuation value is the difference between the initial temperature fluctuation value and the sixth correction value. With this solution, the corrected set temperature fluctuation value can be accurately determined.

[0111] Optionally, the sixth correction value is determined in the following manner, including:

[0112] If the difference between the indoor temperature trough value after the valve is opened and the set temperature of the radiant air conditioner is less than or equal to a1, the sixth correction value is determined to be a1.

[0113] If the difference between the indoor temperature trough value after the valve is opened and the set temperature of the radiant air conditioner is less than or equal to a2, the sixth correction value is determined to be a2.

[0114] If the difference between the indoor temperature trough value after the valve is opened and the set temperature of the radiant air conditioner is less than or equal to a3, the sixth correction value is determined to be a3. Wherein, a1 < a2 < a3. As an example, a1 is 0.1, a2 is 0.2, and a3 is 0.3. With this solution, the sixth correction value can be accurately determined.

[0115] In an optimized solution, in order to more precisely determine the corrected set temperature fluctuation value for the next cycle, the fourth correction value, the fifth correction value, or the sixth correction value can be divided by 2 respectively during the calculation of the corrected set temperature fluctuation value for the previous cycle, so as to be used as the fourth correction value, the fifth correction value, or the sixth correction value for the next cycle, which is convenient for providing favorable data for the correction of the set temperature fluctuation value for the next cycle.
