Therefore, homes are often equipped with floor heating and / or air conditioners to provide heating to the room. However, the heating uniformity of the air conditioner is not enough, and the heat exchange effect is also poor in the cold winter. Heating in the north with an air conditioner will affect the heating effect. The floor heating temperature is more uniform and more comfortable, which meets the needs of cold weather in the north. However, floor heating heats up very slowly. When the floor heating is turned on, it takes a long time for the indoor temperature to gradually rise to the temperature required by the user.

[0034] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0035] In the north, the winter is quite cold, and a heating system is needed to raise the indoor temperature. Therefore, homes are often equipped with floor heating and / or air conditioners to provide heating to the room. However, the heating uniformity of the air conditioner is not enough, and the heat exchange effect is also poor in the cold winter. Heating with an air conditioner in the north will affect the heating effect. The floor heating temperature is more uniform and more comfortable, which meets the needs of cold weather in the north. However, floor heating heats up very slowly. When the floor heating is turned on, it takes a long time for the indoor temperature to gradually rise to the temperature required by the user. It cannot meet the user's needs for a long time, so the use effect of the heating system affects the user's experience. In the related art, the air conditioner and floor heating are generally controlled independently. The air conditioner operates according to the set temperature, and the floor heating is also controlled according to the set water temperature. In this way, in heating control, if the air conditioner and floor heating are turned on at the same time, not only can the respective advantages of floor heating and air conditioning not be fully utilized to make the indoor temperature reach a comfortable temperature quickly, but energy is also wasted. For example, while the floor heating is heating up, the air conditioner also gradually increases its operating parameters according to the heating trend, or the operating parameters gradually tend to the set temperature. At this time, the comfort level of the indoor temperature decreases, and the heat generated by the air conditioner and floor heating is lost.

[0036] Based on this, an embodiment of the present invention provides a method for controlling a heat exchange system in linkage. When the first heat exchange system provides heat to the room, the first temperature in the action space of the first heat exchange system is obtained, and the operating parameters of the second heat exchange system are determined based on the first temperature, and the operation of the second heat exchange system is controlled according to the operating parameters. That is, the first heat exchange system controls the second heat exchange system in linkage, and the operating parameters of the second heat exchange system are related to the heat exchange effect of the first heat exchange system, such as the first temperature and the operating parameters of the second heat exchange system are negatively correlated. In this way, for the first heat exchange system with a slower heat exchange speed, the temperature can be supplemented by the second heat exchange system, thereby increasing the temperature change rate in the room. For the second heat exchange system with a faster heat exchange speed, the temperature can be adjusted based on the first temperature of the action space of the first heat exchange system, and it can be adjusted to adapt to the changes in the effect of the first heat exchange system on the room, thereby reducing the energy consumption of the second heat exchange system.

[0037] In order to better understand the technical solutions provided by the embodiments of the present invention, exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0038] As an implementation method, the hardware environment architecture involved in the heat exchange system linkage control method can be as follows: Figure 1 shown.

[0039] Optionally, the hardware architecture involved in the heat exchange system linkage control method includes a first heat exchange system and a second heat exchange system, such as the first heat exchange system is floor heating, and the second heat exchange system is an air conditioner. Optionally, the execution terminal of this embodiment can be the second heat exchange system, or it can be a smart home control system, such as the association relationship between the second heat exchange system configuration and the first heat exchange system, when the first heat exchange system is started, the second heat exchange system obtains the heat exchange information of the first heat exchange system to adjust the operating parameters. Alternatively, the smart home control system is connected to the first heat exchange system and the second heat exchange system, and the smart home control system controls the operation of the second heat exchange system based on the operation of the first heat exchange system to achieve linkage control of the heat exchange system.

[0040] As an implementation, the execution terminal includes: a processor 101, such as a CPU, a memory 102, and a communication bus 103. The communication bus 103 is used to realize the connection and communication between these components. The processor 101 is used to call an application to execute a control operation.

[0041] The memory 102 may be a high-speed RAM memory or a stable memory (non-volatile memory), such as a disk memory.

[0042] It can be understood that, in one embodiment, a linkage control program for implementing the linkage control of the heat exchange system is stored in the memory 102, or in a computer-readable storage medium. When the processor 101 calls the linkage control program from the memory 102 or the computer-readable storage medium, the following operations are performed:

[0043] Acquiring a first temperature in an action space of a first heat exchange system;

[0044] determining an operating parameter of a second heat exchange system based on the first temperature, wherein the first temperature and the operating parameter of the second heat exchange system are negatively correlated, and a heat exchange rate of the second heat exchange system is greater than that of the first heat exchange system;

[0045] The operation of the second heat exchange system is controlled according to the operating parameters.

[0046] Based on the hardware architecture of the above-mentioned air conditioner or mobile device, the following embodiments of the present invention are proposed.

[0047] First embodiment

[0048] Please refer to Figure 2 The heat exchange system linkage control method proposed in the embodiment of the present invention comprises the following steps:

[0049] Step S110, obtaining a first temperature in an action space of a first heat exchange system;

[0050] The heat exchange system involved in the embodiment of the present invention includes but is not limited to air conditioners, floor heating, steam heat exchange and other heating systems. As long as it involves the linkage control of the heat exchange system, it falls within the scope of protection requested by the embodiment of the present invention. In order to make the embodiment of the present invention easier to understand, the following is an example in which the first heat exchange system is floor heating and the second heat exchange system is air conditioners.

[0051] In the application of this embodiment, the first heat exchange system and the second heat exchange system act on the same space. The first heat exchange system and the second heat exchange system are both turned on. Among them, the first heat exchange system and the second heat exchange system can be manually turned on by the user. For example, when the first heat exchange system and the second heat exchange system are both turned on, the process of heat exchange system linkage control in this embodiment is executed. Alternatively, the second heat exchange system can be automatically started based on the linkage relationship between the first heat exchange system and the second heat exchange system when the first heat exchange system is turned on. Alternatively, when the first heat exchange system is turned on, the second heat exchange system is automatically started under the preset conditions, and the preset conditions are such as: if the absolute value of the difference between the first temperature and the target temperature is greater than or equal to the first preset threshold value, it means that the first heat exchange system still needs a relatively long heat exchange time to reach the target temperature. At this time, the second heat exchange system is started, and the operating parameters of the second heat exchange system are determined according to the difference.

[0052] In this embodiment, the first temperature refers to the temperature of the first heat exchange system acting on the action space. For example, if the first heat exchange system is floor heating, the first temperature is the floor temperature. Alternatively, the first temperature is the heat exchange temperature of the first heat exchange system, such as the water temperature of the floor heating.

[0053] Optionally, this embodiment is applied to a heating process.

[0054] Step S120, determining operating parameters of a second heat exchange system based on the first temperature;

[0055] In this embodiment, the heat exchange rate of the second heat exchange system is greater than that of the first heat exchange system. Therefore, when the first heat exchange system is turned on, in order to quickly reach the comfortable temperature required by the user in the room, the second heat exchange system is started in conjunction.

[0056] Optionally, the second heat exchange system is an air conditioner, and the heat exchange speed of the air conditioner can be adjusted. For example, when the air conditioner is turned on, it runs at a maximum operating frequency to increase the heat exchange speed.

[0057] However, the first heat exchange system gradually heats up over time, and the temperature becomes higher and higher, and the indoor heat exchange demand based on the first heat exchange system gradually increases. At this time, the heat exchange demand for the second heat exchange system is relatively reduced, that is, as the opening time of the first heat exchange system gradually increases, the heat exchange capacity of the first heat exchange system becomes larger and larger, and the heat exchange demand for the second heat exchange system is relatively reduced. It can be seen that in this embodiment, the heat exchange demand for the first heat exchange system and the second heat exchange system is negatively correlated, and therefore, the first temperature and the operating parameters of the second heat exchange system are also negatively correlated. For example, the higher the first temperature of the first heat exchange system for the action space, the lower the demand for the second heat exchange system, and the smaller the operating parameters of the second heat exchange system can be.

[0058] In an optional embodiment, the corresponding relationship between the first temperature and the operating parameters of the second heat exchange system can be preset, and then the corresponding operating parameters of the second heat exchange system can be directly obtained based on the first temperature obtained. For example, as the first temperature changes, the operating parameters of the second heat exchange system are continuously adjusted accordingly. It should be noted that this embodiment is applied to the startup stage of the first heat exchange system before the target temperature set by the user is reached.

[0059] Alternatively, in an optional embodiment, the operating parameters of the second heat exchange system may be determined based on the first temperature in other ways, such as the second embodiment and the third embodiment described below.

[0060] Step S130, controlling the operation of the second heat exchange system according to the operating parameters.

[0061] The heat exchange rate of the second heat exchange system is greater than that of the first heat exchange system. For example, the second heat exchange system is an air conditioner and the first heat exchange system is floor heating. In the initial stage of startup, the air conditioner can operate at a maximum operating frequency or a high operating frequency. In this way, the heat exchange rate of the air conditioner is greater than the heat exchange rate of the floor heating.

[0062] In the actual working process, steps S110 to S130 are repeatedly executed every other cycle, and thus, the operating parameters of the second heat exchange system are adjusted every other cycle. In this way, based on the heat exchange situation of the first heat exchange system, the operating parameters of the second heat exchange system are continuously coordinated, so that when floor heating is used for heating, the indoor temperature can quickly reach the user's required temperature, improve the heating effect, and the floor heating and air conditioner are controlled in linkage, which can also avoid energy waste.

[0063] In this embodiment, when the heat exchange speed of the first heat exchange system is slow, the second heat exchange system is started by linkage, so that the purpose of rapid heat exchange can be achieved indoors. And the operating parameters of the second heat exchange system are determined by the first temperature of the action space of the first heat exchange system. The operating parameters of the second heat exchange system change based on the first temperature of the first heat exchange system. If the first temperature tends to the target temperature, the corresponding operating parameters of the second heat exchange system tend to the minimum value, avoiding energy waste of the second heat exchange system. The linkage control of the first heat exchange system and the second heat exchange system can realize that when the first heat exchange system cannot meet the energy demand, the second heat exchange system provides the energy demand, so that the indoor temperature quickly reaches a comfortable temperature and improves comfort; when the first heat exchange system meets the energy demand, the first heat exchange system is given priority to provide the energy demand. The first heat exchange system is comfortable and does not affect the indoor humidity, so that the indoor temperature remains relatively comfortable. That is, the intelligent linkage control of the first heat exchange system and the second heat exchange system in this embodiment takes into account the advantages of the first heat exchange system and the second heat exchange system, and improves comfort and energy saving effects.

[0064] Second embodiment

[0065] Please refer to Figure 3 Based on the above first embodiment, this embodiment proposes a method for determining the operating parameters of the second heat exchange system. In this embodiment, the step of determining the operating parameters of the second heat exchange system based on the first temperature includes:

[0066] Step S121, calculating the difference between the target temperature and the first temperature;

[0067] Step S122: determining operating parameters of the second heat exchange system according to the difference.

[0068] In this embodiment, the target temperature refers to the target temperature of the user's indoor heating demand. For example, the set temperature of the first heat exchange system, or the set ambient temperature of the working space where the first heat exchange system and the second heat exchange system are located. The operating parameters of the second heat exchange system are adjusted by judging the difference between the first temperature provided by the first heat exchange system to the working space and the target temperature. As the first temperature is constantly changing, the difference from the target temperature is also constantly changing. In this way, during the operation, the operating parameters of the second heat exchange system are constantly adjusted.

[0069] Compared with directly presetting the mapping relationship between the first temperature and the operating parameters of the second heat exchange system, this embodiment calculates the operating parameters of the second heat exchange system by the difference between the target temperature and the first temperature. It can be accurately calculated in combination with the user's actual needs for the environment, and the operating parameters of the second heat exchange system can be adjusted according to the temperature difference requirements to achieve more precise control and enhance intelligent control.

[0070] Optionally, in this embodiment, if the second heat exchange system is an air-conditioning system, the operating parameters include but are not limited to the operating frequency of the air conditioner, the fan speed, the opening of the electronic expansion valve, etc.

[0071] The following lists implementation methods for determining the operating parameters of the second heat exchange system based on the temperature difference:

[0072] For example, in one embodiment, a correspondence between a temperature difference and an operating parameter is preset, and the operating parameter of the second heat exchange system is directly determined based on the temperature difference.

[0073] As in another embodiment, the correspondence between the preset temperature difference interval and the operating parameter is configured with at least two intervals. This embodiment takes two intervals as an example: a first interval and a second interval.

[0074] If the difference is in a first interval, the first operating parameter corresponding to the first interval is the operating parameter of the second heat exchange system.

[0075] If the difference is in the second interval, the second operating parameter corresponding to the second interval is the operating parameter of the second heat exchange system.

[0076] It should be noted that, in this embodiment, the difference is the absolute value of the difference between the target temperature and the first temperature.

[0077] Among them, the minimum value of the first interval is greater than the maximum value of the second interval, and the first operating parameter is greater than the second operating parameter. That is, when the difference is in the first interval, the difference is larger, the temperature of the floor heating is farther from reaching the desired temperature, and the required air conditioning capacity is stronger. Therefore, the first operating parameter corresponding to the first interval is configured to be larger. When the difference is in the first interval, the operating parameter of the second heat exchange system is larger. Based on the large demand for indoor heat exchange by the second heat exchange system, the indoor temperature reaching speed is increased. When the difference is in the second interval, the difference is smaller, the temperature of the floor heating is closer to reaching the desired temperature, and the required air conditioning capacity is weaker. Therefore, the second operating parameter corresponding to the second interval is configured to be smaller. When the difference is in the second interval, the energy consumption of the second heat exchange system is reduced based on the small demand for indoor heat exchange by the second heat exchange system.

[0078] Optionally, in order to further improve the control accuracy and control effect, more temperature difference intervals can be configured, such as 4 temperature difference intervals: the first interval, the second interval, the third interval and the fourth interval;

[0079] Among them, the corresponding relationship between the temperature difference range and the operating parameters (taking the operating frequency as an example) is as follows Table 1:

[0080] Table 1:

[0081] Temperature difference △T Absolute frequency The first interval (△T≥4℃) 60HZ The second interval (△T≥2℃and△T<4℃) 42HZ The third interval (△T≥0℃and△T<2℃) 24HZ The fourth interval (△T<0℃) 0HZ

[0082] In Table 1, the absolute frequency refers to the fixed frequency corresponding to each pre-set interval, which has nothing to do with the equipment parameters of the second heat exchange system. Optionally, the absolute frequency is obtained based on experimental tests. When the absolute value of the difference between the first heat exchange system and the target temperature is in the corresponding interval, the second heat exchange system is operated based on the corresponding operating parameters, which can meet the rapid heating demand while giving priority to floor heating, achieving a uniform and comfortable effect, and taking into account the advantages of floor heating and air conditioning.

[0083] In another embodiment, a correspondence between a preset temperature difference interval and a relative coefficient is provided, wherein the relative coefficient refers to a relative coefficient of a rated operating parameter of the second heat exchange system, and a specific operating parameter is determined according to the rated operating parameter and the relative coefficient. If at least two intervals are configured, this embodiment takes two intervals as an example: a first interval and a second interval.

[0084] If the difference is in a first interval, determining a first relative coefficient associated with the first interval, and determining the operating parameters of the second heat exchange system according to the rated operating parameters of the second heat exchange system and the first relative coefficient;

[0085] If the difference is in a second interval, determining a second relative coefficient associated with the second interval, and determining the operating parameters of the second heat exchange system according to the rated operating parameters of the second heat exchange system and the second relative coefficient;

[0086] It should be noted that, in this embodiment, the difference is the absolute value of the difference between the target temperature and the first temperature.

[0087] Among them, the minimum value of the first interval is greater than the maximum value of the second interval, and the first operating parameter is greater than the second operating parameter. That is, when the difference is in the first interval, the difference is larger, the temperature of the floor heating is farther from reaching the desired temperature, and the required air conditioning capacity is stronger. Therefore, the first relative coefficient corresponding to the first interval is configured to be larger. When the difference is in the first interval, the operating parameters of the second heat exchange system are larger. Based on the large demand for indoor heat exchange by the second heat exchange system, the indoor temperature reaching speed is increased. When the difference is in the second interval, the difference is smaller, the temperature of the floor heating is closer to reaching the desired temperature, and the required air conditioning capacity is weaker. Therefore, the second relative coefficient corresponding to the second interval is configured to be smaller. When the difference is in the second interval, based on the small demand for indoor heat exchange by the second heat exchange system, the energy consumption of the second heat exchange system is reduced.

[0088] Optionally, in order to further improve the control accuracy and control effect, more temperature difference intervals can be configured, such as 4 temperature difference intervals: the first interval, the second interval, the third interval and the fourth interval;

[0089] Among them, the corresponding relationship between the temperature difference range and the operating parameters (taking the operating frequency as an example) is shown in Table 2 below:

[0090] Table 2:

[0091] Temperature difference △T Relative coefficient The first interval (△T≥4℃) 100％ The second interval (△T≥2℃and△T<4℃) 70％ The third interval (△T≥0℃and△T<2℃) 40％ The fourth interval (△T<0℃) 0％

[0092] In Table 2, the relative coefficient refers to the ratio relative to the rated frequency.

[0093] This embodiment pre-configures the relative coefficient corresponding to each temperature difference interval, and then calculates the operating parameters required for the second heat exchange system based on the equipment information (rated operating parameters) of the second heat exchange system and the relative coefficient. For example, if the rated frequency is W, the required operating frequency is W*relative coefficient.

[0094] This embodiment uses relative coefficients to calculate the operating parameters of the second heat exchange system, combined with the rated operating parameters of the second heat exchange system. If the rated operating parameters are larger, then the larger rated operating parameters can be used for operation. If the rated operating parameters are smaller, then a smaller rated operating frequency is used for operation. This adapts to various types of second heat exchange systems, increases the universality of the linkage method of the embodiment of the present invention, and enables the indoor heating demand to be quickly met while giving priority to floor heating to achieve a uniform and comfortable effect, taking into account the advantages of floor heating and air conditioning.

[0095] Compared with the above implementations, the present implementation differs in that: with relative frequency, the heating capacity of the air conditioner is controlled according to the relative coefficient of the rated frequency; with absolute frequency, the heating capacity of the air conditioner is controlled according to the absolute frequency value.

[0096] Take floor heating and air conditioning as an example: turn on the linkage control of floor heating and air conditioning; the user sets 26℃, then the floor heating temperature and air conditioning temperature are both set to 26℃.

[0097] When the floor heating and air conditioning are started in conjunction for 0min to 5min, the floor heating water temperature is 15℃, and the temperature difference from reaching the desired temperature is △T=11℃, the air conditioner maintains 100% rated frequency operation, or operates at 60HZ.

[0098] 5min to 15min, the floor heating water temperature is 23℃, and the temperature difference from reaching the desired temperature is △T=3℃, so the air conditioner maintains 70% of the rated frequency, or runs at 42HZ.

[0099] From 15min to 25min, the floor heating water temperature is 25℃, and the temperature difference from reaching the desired temperature is △T=1℃. The air conditioner will maintain 40% of the rated frequency, or run at 24HZ.

[0100] Optionally, in this embodiment, the mapping relationship between the interval and the operating parameter / relative coefficient can be a factory default setting, or can be preset by the user, or can be automatically generated based on self-learning of user behavior habits over a period of time, or can be generated based on self-learning of a large amount of data within a preset distance range.

[0101] Optionally, in this embodiment, after the step of controlling the second heat exchange system according to the operating parameters, the step further includes:

[0102] If the difference is less than a second preset threshold, the second heat exchange system is closed.

[0103] For example, the second preset threshold is 0 to 1, etc. When the difference between the target temperature and the first temperature is less than the second preset threshold, it means that the heat exchange capacity of the first heat exchange system meets the user's needs and the second heat exchange system is not needed. At this time, the second heat exchange system can be turned off to reduce resource waste.

[0104] The temperature of the first heat exchange system is more even and more comfortable, while the temperature rise rate of the second heat exchange system is fast. In this embodiment, the first heat exchange system and the second heat exchange system are coordinated and controlled. When the temperature provided by the first heat exchange system is low, the heat exchange capacity of the second heat exchange system is increased to meet the demand for rapid heating; when the temperature provided by the first heat exchange system is high, the heat exchange capacity of the second heat exchange system is reduced to make heating more comfortable; the advantages of the first heat exchange system and the second heat exchange system are taken into account.

[0105] Third embodiment

[0106] Based on the above first embodiment, this embodiment proposes another embodiment of determining the operating parameters of the second heat exchange system. In this embodiment, the step of determining the operating parameters of the second heat exchange system based on the first temperature includes:

[0107] determining a first temperature change rate of the first heat exchange system based on the first temperature and the first temperature collected before a preset time interval;

[0108] The operating parameters of the second heat exchange system are determined according to a preset relationship between the first temperature change rate and the second temperature change rate of the second heat exchange system.

[0109] In this embodiment, a corresponding relationship between the first temperature change rate of the first heat exchange system and the second temperature change rate of the second heat exchange system is preset. When the first temperature change rate is faster, the speed of adjusting the operating parameters of the corresponding second heat exchange system is also correspondingly accelerated. When the energy of the first heat exchange system is increased, the energy of the second heat exchange system is correspondingly reduced.

[0110] The second temperature refers to the temperature provided by the second heat exchange system to the active space.

[0111] The heat exchange rate of the first heat exchange system can be determined according to the first temperature change rate. When the heat exchange rate of the first heat exchange system is faster, the operating parameters of the second heat exchange system can be adjusted to be smaller, and when the heat exchange rate of the first heat exchange system is slower, the operating parameters of the second heat exchange system can be adjusted to be larger.

[0112] Alternatively, in other embodiments, the operating parameters further include an adjustment period of the operating parameters. When the heat exchange rate of the first heat exchange system is faster, the adjustment period is shortened. When the heat exchange rate of the first heat exchange system is slower, the adjustment period is extended to reduce the number of adjustments.

[0113] This embodiment realizes coordinated control of the first heat exchange system and the second heat exchange system. The second heat exchange system can be adjusted based on the actual operation of the first heat exchange system, thereby increasing the coordination effect and improving the intelligent control.

[0114] The present invention also provides a heat exchange system linkage control device, which includes a memory, a processor, and a linkage control program stored in the memory and executable on the processor. When the linkage control program is executed by the processor, the steps of the heat exchange system linkage control method as described above are implemented.

[0115] Optionally, it further comprises a first heat exchange system and / or a second heat exchange system, wherein the first heat exchange system comprises floor heating, and the second heat exchange system comprises an air conditioner.

[0116] The present invention also provides a computer-readable storage medium, wherein the computer-readable storage medium stores a linkage control program, and when the linkage control program is executed by a processor, the steps of the linkage control method for a heat exchange system as described above are implemented.

[0117] It should be noted that the above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
