However, in the actual operation process, due to various working conditions, the set temperature and the indoor temperature reach a dynamic equilibrium state, and the room will always be in a state of energy demand, resulting in energy consumption, and the room temperature will not meet the set requirements, affecting the user experience. Summary of the invention

[0003] The present invention aims to solve one of the technical problems in the related art to at least some extent. To this end, the first object of the present invention is to provide a control method for a radiant air conditioner, which controls the top water collector and the bottom water collector to open in combination with the outdoor temperature when the indoor temperature and the set temperature are in a state of dynamic equilibrium for a long time, so that the indoor temperature reaches the set temperature faster, reduces energy consumption, and improves the user experience.

[0019] According to one embodiment of the present invention, when the radiant air conditioner does not enter cooling operation or heating operation, the method further includes: controlling the top manifold and the bottom manifold to stop outputting circulating water to the top radiant terminal and the bottom radiant terminal respectively.

[0020] To achieve the above-mentioned purpose, according to the second aspect of the present invention, a computer-readable storage medium is proposed, on which a control program for a radiant air conditioner is stored.

[0033] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0034] It should be noted that this application is made based on the inventor's understanding and research of the following issues:

[0035] In the case of radiant air conditioning cooling operation, the control logic of the top manifold and the floor manifold is as follows: Figure 1 As shown, T1_Rn is the room temperature, T1S_Rn is the room set temperature, and dT1SC is the first preset temperature. When the room temperature T1_Rn rises to the temperature sum of the room set temperature T1S_Rn and the first preset temperature dT1SC, the manifold on the top is controlled to be opened, and the manifold on the floor is controlled to be closed; when the room temperature T1_Rn rises to the temperature sum of the room set temperature T1S_Rn plus 4°C, the manifold on the top and the manifold on the floor are controlled to be opened at the same time; when the room temperature T1_Rn drops to the temperature sum of the room set temperature T1S_Rn plus 2°C, the manifold on the top is controlled to be opened, and the manifold on the floor is controlled to be closed; when the room temperature T1_Rn drops to the temperature difference of the room set temperature T1S_Rn minus 0.5°C, the manifold on the top and the manifold on the floor are controlled to be closed at the same time.

[0036] In the case of radiant air conditioning heating operation, the control logic of the top manifold and the floor manifold is as follows: Figure 2 As shown, dT1SC is the second preset temperature. When the room temperature T1_Rn rises to the temperature difference of the room setting temperature T1S_Rn minus 2°C, the manifold on the floor is controlled to open, and the manifold on the top is controlled to close; when the room temperature T1_Rn rises to the temperature sum of the room setting temperature T1S_Rn plus 0.5°C, the manifold on the top and the manifold on the floor are controlled to close at the same time; when the room temperature T1_Rn drops to the temperature sum of the room setting temperature T1S_Rn plus the second preset temperature, the manifold on the floor is controlled to open, and the manifold on the top is controlled to close; when the room temperature T1_Rn drops to the temperature difference of the room setting temperature T1S_Rn minus 4°C, the manifold on the top and the manifold on the floor are controlled to open at the same time.

[0037] Therefore, the control logic of the top manifold and the floor manifold in the related technology only takes the temperature difference between the room temperature and the room set temperature as the control condition. During the actual operation, the room temperature and the room set temperature will reach a dynamic balance. For example, the temperature difference between the room temperature and the room set temperature is stable between 2°C and 4°C. At this time, the manifold is always in the open state, which will consume energy, and the room temperature will not reach the room set temperature, affecting the user experience.

[0038] Based on this, an embodiment of the present invention provides a radiant air conditioner and its control method, an indoor host, and a storage medium. When the indoor temperature and the set temperature are in a state of dynamic equilibrium for a long time, the top and bottom water collectors are controlled to open in combination with the outdoor temperature, so that the indoor temperature is accelerated to reach the set temperature, reducing energy consumption and improving the user experience.

[0039] The following describes the radiant air conditioner and its control method, indoor host, and storage medium according to the embodiments of the present invention with reference to the accompanying drawings.

[0040] Figure 3 Schematic diagram of a radiant air conditioner system according to an embodiment of the present invention. Figure 3 As shown, the radiation air conditioner includes: a top water collector 10, a bottom water collector 20, an indoor host 30, a temperature sensor 40, a top radiation terminal 50 and a bottom radiation terminal 60.

[0041] Among them, the top radiation terminal 50 and the bottom radiation terminal 60 are installed in each room, the top radiation terminal 50 is installed on the indoor ceiling, and the bottom radiation terminal 60 is installed on the indoor floor. The top radiation terminal 50 and the bottom radiation terminal 60 are suitable for exchanging heat and cold between circulating water and indoor air, thereby achieving heating or cooling. The top water collector 10 is suitable for outputting circulating water to the top radiation terminal 50, and the bottom water collector 20 is suitable for outputting circulating water to the bottom radiation terminal 60. The temperature sensor 40 is set in each room and is suitable for detecting the indoor temperature of each room. The control method of the radiation air conditioner of this embodiment is applied to the indoor host 30, and the indoor host 30 is suitable for connecting to the wire controller 70 in the room. The user sets the set temperature by operating the wire controller 70, and the wire controller 70 sends the set temperature to the indoor host 30. The indoor host 30 controls the top water collector 10 and the bottom water collector 20 switches according to the set temperature and the indoor temperature.

[0042] It should be noted that the top radiation terminal 50 may be a radiation panel, and the bottom radiation terminal 60 may be a floor heating coil.

[0043] Figure 4 FIG. 1 is a flow chart of a control method of a radiant air conditioner according to an embodiment of the present invention. Figure 4 As shown, the control method of the radiation air conditioner includes the following steps:

[0044] S101, obtaining indoor temperature and outdoor temperature.

[0045] Specifically, the outdoor temperature will affect the indoor temperature. Although the indoor temperature and the set temperature reach a dynamic balance within a period of time, the indoor temperature is affected by the outdoor temperature and will change after a long time. Therefore, the control method of this embodiment also needs to take the outdoor temperature as a control condition. The outdoor temperature can be obtained by the outdoor temperature sensor of the radiant air conditioner.

[0046] S102, when it is determined that the temperature difference between the indoor temperature and the set temperature, and the outdoor temperature meets the preset conditions and lasts for a preset time, the top manifold and the bottom manifold are controlled to output circulating water to the top radiation terminal and the bottom radiation terminal respectively, so as to accelerate the indoor temperature to reach the set temperature.

[0047] Specifically, the temperature difference is the difference between the set temperature and the indoor temperature. The value range of the temperature difference is different when the radiant air conditioner is in cooling operation or heating operation. When the temperature difference meets the preset conditions and lasts for a preset period of time, it indicates that the indoor temperature and the set temperature have reached a dynamic balance within the preset period of time. Combined with the outdoor temperature, it is judged that the cooling or heating supply in the current room is insufficient. Therefore, it is necessary to control the top manifold and the bottom manifold to output circulating water to the top radiation terminal and the bottom radiation terminal respectively, so that the top radiation terminal and the bottom radiation terminal can exchange heat with the indoor air at the same time, so that the indoor temperature is accelerated to reach the set temperature.

[0048] For example, when the radiant air conditioner is in cooling operation, the indoor temperature is greater than the set temperature. If the temperature difference between the set temperature and the indoor temperature is between -4℃ and -2℃ and the outdoor temperature is greater than or equal to the first preset temperature threshold, the preset condition is met and it lasts for 120 minutes, then it is determined that the cooling capacity of the current room is insufficient, and the top manifold and the bottom manifold are controlled to output circulating cold water to the top radiation terminal and the bottom radiation terminal respectively. The top radiation terminal and the bottom radiation terminal simultaneously perform heat exchange with the indoor air, so that the indoor temperature is quickly reduced to the set temperature. When the radiant air conditioner is in heating operation, the indoor temperature is less than the set temperature. If the temperature difference between the set temperature and the indoor temperature is between 2℃ and 4℃ and the outdoor temperature is less than or equal to the second preset temperature threshold, the preset condition is met and it lasts for 120 minutes, then it is determined that the heating capacity of the current room is insufficient. The top manifold and the bottom manifold are controlled to output circulating hot water to the top radiation terminal and the bottom radiation terminal respectively. The top radiation terminal and the bottom radiation terminal simultaneously perform heat exchange with the indoor air, so that the indoor temperature is quickly increased to the set temperature.

[0049] In the above embodiment, when the indoor temperature and the set temperature are in a state of dynamic equilibrium for a long time, combined with the judgment of the outdoor temperature, the top and bottom water collectors are controlled to open, actively breaking the equilibrium state between the indoor temperature and the set temperature, accelerating the indoor temperature to reach the set temperature, reducing energy consumption, and improving the user experience.

[0050] In some embodiments, when the radiant air conditioner is in cooling operation, determining whether the temperature difference between the indoor temperature and the set temperature, and the outdoor temperature meet preset conditions includes: when the temperature difference is in a first preset temperature range and the outdoor temperature is greater than or equal to a first preset temperature threshold, determining that the temperature difference and the outdoor temperature meet the preset conditions.

[0051] It is understandable that when the radiant air conditioner is in cooling operation, if the outdoor temperature is greater than or equal to the first preset temperature threshold, it indicates that the outdoor temperature is too high and the indoor temperature will slowly rise. If only the top water collector is controlled to open, it will affect the user experience. Therefore, it is necessary to control the top water collector and the bottom water collector to open at the same time so that the indoor temperature can be quickly reduced to the set temperature.

[0052] In some embodiments, when the temperature difference is within a preset temperature range and the outdoor temperature is less than a first preset temperature threshold, the method further includes: controlling the top manifold to output circulating cold water to the top radiation terminal, and controlling the bottom manifold to stop outputting circulating cold water to the bottom radiation terminal.

[0053] Specifically, when the outdoor temperature is lower than the first preset temperature threshold, it indicates that the outdoor temperature has little impact on the indoor temperature, and the temperature difference changes little and is still within the preset temperature range, which will not have a significant impact on the user experience. Therefore, there is no need to lower the indoor temperature to the set temperature. At this time, only controlling the top water collector to open can meet the cooling needs in the current room.

[0054] In some embodiments, when the temperature difference is greater than the upper limit value of the first preset temperature range and less than the first preset temperature difference threshold, the method also includes: controlling the top manifold to output circulating cold water to the top radiation end, and controlling the bottom manifold to stop outputting circulating cold water to the bottom radiation end.

[0055] Specifically, when the temperature difference is greater than the upper limit of the first preset temperature range and less than the first preset temperature difference threshold, it indicates that the temperature difference between the indoor temperature and the set temperature is not large, and will not have a significant impact on the user experience. Therefore, there is no need to lower the indoor temperature to the set temperature. At this time, only controlling the top water collector to open can meet the cooling needs in the current room.

[0056] For example, if the first preset temperature range is -4℃--2℃, the first preset temperature threshold is 30℃, and the first preset temperature difference threshold is -0.5℃, when the temperature difference is in the first preset temperature range and the outdoor temperature is greater than or equal to 30℃, and lasts for a preset time, the top sub-manifold and the bottom sub-manifold are controlled to output circulating cold water to the top radiation terminal and the bottom radiation terminal respectively; when the temperature difference is in the first preset temperature range and the outdoor temperature is less than 30℃, the top sub-manifold is controlled to output circulating cold water to the top radiation terminal, and the bottom sub-manifold is controlled to stop outputting circulating cold water to the bottom radiation terminal; when the temperature difference is between -2℃--0.5℃, the top sub-manifold is controlled to output circulating cold water to the top radiation terminal, and the bottom sub-manifold is controlled to stop outputting circulating cold water to the bottom radiation terminal.

[0057] In some embodiments, when the temperature difference is less than a lower limit of the first preset temperature interval, the method further includes: controlling the top manifold and the bottom manifold to output circulating water to the top radiation terminal and the bottom radiation terminal respectively.

[0058] It is understandable that if the temperature difference is less than the lower limit of the first preset temperature range, it indicates that the set temperature is too different from the indoor temperature, resulting in a poor user experience. Therefore, it is necessary to control the top and bottom water collectors to open at the same time so that the indoor temperature quickly reaches the set temperature, thereby improving the user experience.

[0059] In some embodiments, when the temperature difference is greater than or equal to a first preset temperature difference threshold, the method further includes: controlling the top manifold and the bottom manifold to stop outputting circulating water to the top radiation terminal and the bottom radiation terminal respectively.

[0060] That is, when the temperature difference is less than or equal to the first preset temperature difference threshold, the indoor temperature is close to the set temperature, and the room does not need to be cooled. Therefore, the top manifold and the bottom manifold are controlled to stop at the same time.

[0061] In some embodiments, when the radiant air conditioning is operating for heating, determining whether the temperature difference between the indoor temperature and the set temperature, and the outdoor temperature meet preset conditions includes: when the temperature difference is in a second preset temperature range and the outdoor temperature is less than or equal to a second preset temperature threshold, determining that the temperature difference and the outdoor temperature meet the preset conditions.

[0062] It is understandable that when the radiant air conditioner is operating in heating mode, if the outdoor temperature is less than or equal to the second preset temperature threshold, it indicates that the outdoor temperature is too low and the indoor temperature will slowly drop. If only the bottom water collector is controlled to open, it will affect the user experience. Therefore, it is necessary to control the top and bottom water collectors to open at the same time so that the indoor temperature can quickly rise to the set temperature.

[0063] In some embodiments, when the temperature difference is within a preset temperature range and the outdoor temperature is greater than a second preset temperature threshold, the method further includes: controlling the bottom manifold to output circulating hot water to the bottom radiation terminal, and controlling the top manifold to stop outputting circulating hot water to the top radiation terminal.

[0064] Specifically, if the outdoor temperature is greater than the second preset temperature threshold, it indicates that the outdoor temperature has little impact on the indoor temperature, and the temperature difference changes little and is still within the preset temperature range, which will not have a significant impact on the user experience. Therefore, there is no need to raise the indoor temperature to the set temperature at this time. Only controlling the bottom manifold to open can meet the heating needs in the current room.

[0065] In some embodiments, when the temperature difference is less than the lower limit of the second preset temperature range and greater than the second preset temperature difference threshold, the method also includes: controlling the bottom manifold to output circulating hot water to the bottom radiation terminal, and controlling the top manifold to stop outputting circulating hot water to the top radiation terminal.

[0066] Specifically, when the temperature difference is less than the minimum value of the preset temperature range and the temperature difference is greater than the preset temperature difference, it indicates that the temperature difference between the indoor temperature and the set temperature is not large, and will not have a significant impact on the user experience. Therefore, there is no need to raise the indoor temperature to the set temperature at this time. Only controlling the bottom manifold to open can meet the heating needs in the current room.

[0067] For example, when the radiant air conditioner is in heating operation, the indoor temperature is lower than the set temperature, so the second preset temperature range is 2°C-4°C, the second preset temperature threshold is 10°C, and the first preset temperature difference threshold is 0.5°C. When the temperature difference is in the second preset temperature range and the outdoor temperature is less than or equal to 10°C, and lasts for a preset period of time, the top manifold and the bottom manifold are controlled to output circulating hot water to the top radiation terminal and the bottom radiation terminal respectively; when the temperature difference is in the second preset temperature range and the outdoor temperature is greater than or equal to 10°C, the bottom manifold is controlled to output circulating hot water to the bottom radiation terminal, and the top manifold is controlled to stop outputting circulating hot water to the top radiation terminal; when the temperature difference is between 0.5°C-2°C, the bottom manifold is controlled to output circulating hot water to the bottom radiation terminal, and the top manifold is controlled to stop outputting circulating hot water to the top radiation terminal.

[0068] In some embodiments, when the temperature difference is greater than an upper limit of the second preset temperature interval, the method further includes: controlling the top manifold and the bottom manifold to output circulating water to the top radiation terminal and the bottom radiation terminal respectively.

[0069] It is understandable that if the temperature difference is greater than the upper limit value of the second preset temperature range, it indicates that the set temperature is too different from the indoor temperature, resulting in a poor user experience. Therefore, it is necessary to control the top and bottom manifolds to open at the same time so that the indoor temperature quickly reaches the set temperature, thereby improving the user experience.

[0070] For example, when the radiant air conditioner is in cooling operation, the indoor temperature is greater than the set temperature. If the temperature difference between the set temperature and the indoor temperature is -5°C, the lower limit of the first preset temperature interval is -4°C, and the cooling capacity of the current room is insufficient, the top manifold and the bottom manifold are controlled to output circulating cold water to the top radiation terminal and the bottom radiation terminal respectively, and the top radiation terminal and the bottom radiation terminal simultaneously perform heat exchange with the indoor air, so that the indoor temperature is quickly reduced to the set temperature. When the radiant air conditioner is in heating operation, the indoor temperature is less than the set temperature. If the temperature difference between the set temperature and the indoor temperature is 5°C, the maximum value of the preset temperature interval is 4°C, and the temperature difference between the indoor temperature and the set temperature exceeds the upper limit of the preset temperature interval, the heating capacity of the current room is insufficient, and the top manifold and the bottom manifold are controlled to output circulating hot water to the top radiation terminal and the bottom radiation terminal respectively, and the top radiation terminal and the bottom radiation terminal simultaneously perform heat exchange with the indoor air, so that the indoor temperature is quickly increased to the set temperature.

[0071] In some embodiments, when the temperature difference is less than or equal to a second preset temperature difference threshold, the method further includes: controlling the top manifold and the bottom manifold to stop outputting circulating water to the top radiation end and the bottom radiation end respectively.

[0072] That is, when the temperature difference is less than or equal to the second preset temperature difference threshold, the indoor temperature is close to the set temperature, and the room does not need to be heated. Therefore, the top manifold and the bottom manifold are controlled to stop at the same time.

[0073] It should be noted that after the top manifold and the bottom manifold are controlled to output circulating water to the top radiation terminal and the bottom radiation terminal respectively, if the temperature difference is less than or equal to the preset temperature difference, the top manifold and the bottom manifold are controlled to stop outputting circulating water to the top radiation terminal and the bottom radiation terminal respectively. When the temperature difference is reduced to below the preset temperature difference, it is considered that the indoor temperature reaches the set temperature. If the top manifold and the bottom manifold are kept turned on at the same time, the temperature difference between the indoor temperature and the set temperature will increase again, thereby affecting the user experience.

[0074] In some embodiments, when the radiant air conditioner does not enter cooling operation or heating operation, the method further includes: controlling the top manifold and the bottom manifold to stop outputting circulating water to the top radiant terminal and the bottom radiant terminal respectively.

[0075] It is understandable that when the radiant air conditioner is not in cooling operation or heating operation, heat exchange is not required in the room. Therefore, the top manifold and the bottom manifold are controlled to stop outputting circulating water to the top radiation terminal and the bottom radiation terminal respectively.

[0076] The technical solution of the present application is further described in detail below in conjunction with specific implementation methods:
