[0023] In conjunction with the above method, another aspect of the present invention provides a control device for a dual-supply system, the dual-supply system having air conditioning and underfloor heating; the control method for the dual-supply system includes: an acquisition unit configured to acquire indoor environmental parameters of the dual-supply system, indoor user activity parameters of the dual-supply system, and outdoor environmental parameters of the dual-supply system when the dual-supply system is in operation; and a control unit configured to control the operation mode of the dual-supply system based on the indoor environmental parameters of the dual-supply system, combined with the indoor user activity parameters and / or the outdoor environmental parameters of the dual-supply system, so as to enable the air conditioning and the underfloor heating to operate in synergy.

[0024] In conjunction with the aforementioned device, the present invention further provides a dual-supply system, comprising: a control device for the dual-supply system described above.

[0025] In conjunction with the above method, the present invention further provides a storage medium comprising a stored program, wherein, when the program is executed, the device containing the storage medium is controlled to perform the steps of the control method for the dual-supply system described above.

[0026] In conjunction with the above method, the present invention further provides a computer program product, including a computer program that, when executed by a processor, implements the steps of the control method for the dual-supply system described above.

[0027] This invention addresses a dual-supply system comprising air conditioning (i.e., an air-source heat pump system) and underfloor heating (i.e., a water-based underfloor heating system). While the dual-supply system is operating, it acquires indoor environmental parameters, indoor user activity parameters, and outdoor environmental parameters. Based on these indoor environmental parameters, combined with the indoor user activity parameters and / or the outdoor environmental parameters, it controls the system's operation mode, such as adjusting the airflow pattern of the air conditioner and the output pattern of the underfloor heating. Thus, by combining indoor environmental parameters (e.g., indoor vertical temperature difference), indoor user activity parameters (e.g., activity intensity), and outdoor environmental parameters (e.g., outdoor temperature and solar radiation intensity), the system's operation mode is adjusted, improving the synergistic efficiency of air conditioning and underfloor heating, reducing energy consumption, and enhancing comfort. This dual-supply system is an energy-saving air conditioning system.

[0028] Specifically, in the solution of this invention, for a dual-supply system with air conditioning (i.e., an air source heat pump system) and underfloor heating (i.e., a water-based underfloor heating system), after the dual-supply system is powered on and started, the indoor fan of the air conditioner is controlled to automatically sweep air at maximum airflow for a certain period of time (e.g., 3 minutes) to ensure sufficient mixing of indoor air. Then, the operating parameters of the dual-supply system are acquired, specifically including: acquiring the temperature at different indoor heights (e.g., the upper indoor air temperature Tup obtained from the indoor unit's air inlet, the middle indoor air temperature Tmid obtained from the base of the wired controller, and the lower indoor air temperature Tdown obtained from the underfloor heating system), and acquiring the indoor temperature based on millimeter-wave radar. Based on the personnel's location coordinates (x, y, z) and movement speed v, the outdoor ambient temperature Tout and outdoor solar radiation parameter G are obtained. The indoor vertical temperature difference (ΔT_w) is determined based on the upper indoor air temperature Tup, middle indoor air temperature Tmid, and lower indoor air temperature Tdown. The activity intensity (Iact) is determined based on the personnel's location coordinates (x, y, z) and movement speed v. An environmental interference correction factor (Iact) is determined based on the outdoor ambient temperature Tout and outdoor solar radiation parameter G. Finally, based on the indoor vertical temperature difference index ΔT_w and the personnel... The activity intensity index Iact and set temperature Tset adjust the operating mode of the combined heat and power system (such as convection compensation priority mode, radiation maintenance mode, and mixed heating mode). Specifically, if the indoor vertical temperature difference index ΔT_w > the first temperature threshold δ1, and the activity intensity index Iact is at rest, then the operating mode of the combined heat and power system is adjusted to convection compensation priority mode: the compressor in the air conditioner is adjusted to operate at a low to medium frequency; the air outlet direction of the indoor fan in the air conditioner is adjusted to horizontal, the fan speed is adjusted to high, and the fan sweeping mode is adjusted to low-frequency up-and-down sweeping; the water pump in the underfloor heating system is adjusted to run at low speed; after a set time, the system returns to normal operation. Reacquire the operating parameters of the dual-supply system; if the indoor vertical temperature difference index ΔT_w ≤ the second temperature threshold δ2, and the difference between the indoor average temperature (i.e., the average temperature of the upper indoor air temperature Tup, the middle indoor air temperature Tmid, and the lower indoor air temperature Tdown) and the set temperature Tset is within the set difference range, then adjust the operating mode of the dual-supply system to radiation maintenance mode: the compressor in the air conditioner operates at an extremely low frequency, the water underfloor heating system maintains a constant temperature water supply, and the set temperature Tset is adjusted according to the outdoor ambient temperature Tout and the environmental interference correction factor. After the set time, return to reacquire the operating parameters of the dual-supply system.If the indoor vertical temperature difference index ΔT_w ≤ the second temperature threshold δ2, and the indoor average temperature is lower than the set temperature Tset by a certain range, the operating mode of the combined cooling, heating, and air conditioning system is adjusted to a mixed heating mode: the air outlet direction of the air conditioner's indoor fan is adjusted to directional airflow away from people and heated airflow is supplied; the water-based underfloor heating system accelerates heat storage; and the heating ratio of the air conditioner and water-based underfloor heating system is adjusted according to the indoor vertical temperature difference index ΔT_w to reduce the indoor vertical temperature difference. After a set time, the system returns to retrieve the operating parameters of the combined cooling, heating, and air conditioning system. Thus, by combining the indoor vertical temperature difference, the intensity of human activity, the outdoor ambient temperature, and the intensity of solar radiation, the operating mode of the combined cooling, heating, and air conditioning system is adjusted to improve the synergistic efficiency of air conditioning and underfloor heating, reduce energy consumption, and improve comfort. This combined cooling, heating, and air conditioning system is an energy-saving air conditioning system.

[0042] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0043] Considering that the control systems of dual-source heat pump systems typically employ simple temperature feedback mechanisms, they cannot accurately control the heat output of both air-source heat pump systems and water-based underfloor heating systems, resulting in high energy consumption. Specifically, in related solutions, the control systems of dual-source heat pump systems collect temperature signals from a single location via a wired controller or return air vent sensor and compare them with a set temperature to control the compressor frequency and water pump speed. However, this control method has significant drawbacks. For example, human temperature perception varies spatially; the temperature difference between the head and feet is a key indicator of comfort, but single-point temperature measurement in related solutions cannot reflect the vertical temperature gradient. Furthermore, the control systems in these solutions lack awareness of human activity and the local microenvironment, often maintaining high power operation even when people are stationary. Additionally, the control logic of these systems is rigid, unable to predictively adjust based on changes in the indoor and outdoor environment (such as solar radiation and the opening and closing of doors and windows), leading to large indoor temperature fluctuations and low energy efficiency.

[0044] Therefore, there is an urgent need for a control scheme for a combined heat and power (CHP) system that can comprehensively consider vertical temperature distribution, human activity status, and environmental interference factors to achieve refined and personalized thermal comfort regulation. Therefore, this invention proposes a control method for a CHP system, specifically a dynamic indoor thermal comfort regulation method based on multi-source heterogeneous data fusion. This method combines vertical temperature difference, human activity intensity, and local heat load to dynamically optimize the air supply strategy of the air conditioning (i.e., air source heat pump system) and the output ratio of the water-based underfloor heating system, improving the synergistic efficiency of the air conditioning (i.e., air source heat pump system) and water-based underfloor heating system, reducing energy consumption and improving comfort. Related schemes calculate the underfloor heating heating time and determine whether to turn it on or off accordingly, concentrating heat to quickly heat the air conditioning system when the water temperature is low and protecting the water pump, achieving start-up protection and equipment safety. However, this invention collects and processes data from multiple dimensions, including indoor vertical temperature difference (including curvature factor), human activity, and outdoor sunlight, and dynamically allocates the output of the three modes of air conditioning and underfloor heating in synergy and heating ratio, achieving refined comfort and energy-saving control during operation.

[0045] According to an embodiment of the present invention, a control method for a combined cooling, heating, and power (CCHP) system is provided, such as Figure 1 The diagram shows a flowchart of an embodiment of the method of the present invention. The dual-supply system includes air conditioning and underfloor heating; the air conditioning is such as an air-source heat pump system, and the underfloor heating is such as a water-based underfloor heating system; in the solution of the present invention, as... Figure 1 As shown, the control method of the dual power supply system includes steps S110 to S120.

[0046] In step S110, under the heating mode of the combined heat and power system, and while the combined heat and power system is operating, the indoor environmental parameters, indoor user activity parameters, and outdoor environmental parameters of the combined heat and power system are acquired. The indoor environmental parameters include, for example, the upper indoor air temperature Tup obtained from the indoor unit's air inlet, the middle indoor air temperature Tmid obtained from the wired controller base, and the lower indoor air temperature Tdown obtained from the underfloor heating system. The indoor user activity parameters include, for example, the indoor occupant position coordinates (x, y, z) and occupant movement speed v obtained from the UWB device 1 integrated within the air conditioner (i.e., air source heat pump system). The outdoor environmental parameters include, for example, the outdoor ambient temperature Tout obtained from the outdoor temperature sensor 7 and the outdoor solar radiation parameter G obtained from the radiation sensor 6.

[0047] In step S120, based on the indoor environmental parameters of the combined cooling, heating, and power (CCHP) system, combined with the indoor user activity parameters and / or the outdoor environmental parameters of the CCHP system, the operating mode of the CCHP system is controlled to enable the air conditioning and underfloor heating to operate in synergy. This includes adjusting the air outlet mode of the air conditioning system and the output mode of the underfloor heating system to improve the synergistic efficiency of the air conditioning (i.e., air source heat pump system) and the water-based underfloor heating system, thereby reducing energy consumption and improving comfort. Adjusting the operating mode of the CCHP system includes at least one of the following: adjusting the operating mode of the CCHP system to a convection compensation priority mode, adjusting the operating mode of the CCHP system to a radiation sustaining mode, or adjusting the operating mode of the CCHP system to a mixed heating mode.

[0048] In the present invention, when the combined cooling, heating, and power (CCHP) system is operating, indoor environmental parameters, indoor user activity parameters, and outdoor environmental parameters of the CCHP system are acquired. Based on the indoor environmental parameters, combined with the indoor user activity parameters and / or the outdoor environmental parameters, the operating mode of the CCHP system is controlled, such as adjusting the air outlet mode of the air conditioner and the output mode of the underfloor heating. Thus, by combining the indoor environmental parameters, indoor user activity parameters, and outdoor environmental parameters, the operating mode of the CCHP system is adjusted, improving the synergistic efficiency of air conditioning and underfloor heating, reducing energy consumption, and enhancing comfort.

[0049] In some implementations, step S110, obtaining the indoor environmental parameters of the combined heat and power system, includes:

[0050] The indoor ambient temperature detected by the first temperature sensor 3 at a first set height in the room where the dual-supply system is located, the indoor ambient temperature detected by the second temperature sensor 4 at a second set height in the room where the dual-supply system is located, and the indoor ambient temperature detected by the third temperature sensor 5 at a third set height in the room where the dual-supply system is located are obtained and recorded as the indoor ambient temperature at the first height of the dual-supply system, the indoor ambient temperature at the second height of the dual-supply system, and the indoor ambient temperature at the third height of the dual-supply system, respectively, as the indoor environmental parameters of the dual-supply system; the first set height includes the return air vent of the indoor unit of the air conditioner, the second set height includes the wired controller of the air conditioner, and the third set height includes the contact point between the buried pipe 2 of the underfloor heating and the ground. The indoor ambient temperature at the first set height in the room where the dual-supply system is located is, for example, the upper indoor air temperature Tup obtained from the first temperature sensor 3 at the air inlet of the indoor unit; the indoor ambient temperature at the second set height in the room where the dual-supply system is located is, for example, the middle indoor air temperature Tmid obtained from the base of the wired controller; the indoor ambient temperature at the third set height in the room where the dual-supply system is located is, for example, the lower indoor air temperature Tdown obtained from the underfloor heating system.

[0051] And / or, in step S110, the indoor user activity parameters of the combined heat and power system are obtained, including:

[0052] The location and velocity parameters of the user, detected by a millimeter-wave radar located in the room where the combined cooling, heating, and power (CCHP) system is located, are recorded as the user location parameters and velocity parameters of the CCHP system, respectively, and used as the indoor user activity parameters of the CCHP system. The location of the millimeter-wave radar includes the location of the indoor unit of the air conditioner. The user location parameters in the room where the CCHP system is located are, for example, the indoor personnel location coordinates (x, y, z) obtained based on the UWB device 1 integrated into the air conditioner (i.e., air source heat pump system). The user velocity parameters in the room where the CCHP system is located are, for example, the personnel movement velocity v obtained based on the UWB device 1 integrated into the air conditioner (i.e., air source heat pump system).

[0053] And / or, in step S110, obtaining the outdoor environmental parameters of the combined heat and power system includes:

[0054] The outdoor ambient temperature detected by the outdoor temperature sensor 7, located outside the room where the combined heat and power system is located, and the outdoor solar radiation parameter detected by the outdoor solar radiation sensor 6, located outside the room where the combined heat and power system is located, are obtained and recorded as the outdoor ambient temperature and the outdoor solar radiation parameter of the combined heat and power system, respectively, and are used as the outdoor environmental parameters of the combined heat and power system. The outdoor ambient temperature of the room where the combined heat and power system is located is, for example, the outdoor ambient temperature Tout obtained by the outdoor temperature sensor 7; the outdoor solar radiation parameter of the room where the combined heat and power system is located is, for example, the outdoor solar radiation parameter G obtained by the solar radiation sensor 6.

[0055] The present invention provides a dynamic control scheme for indoor thermal comfort based on multi-source heterogeneous data fusion for a dual-supply system, which can be applied to home decoration environments equipped with air source heat pump air conditioning indoor units (i.e., air source heat pump systems) and water underfloor heating systems. Figure 8 This is a structural schematic diagram of an embodiment of a dual-power system, which can show the connection diagram and location of each device in the dual-power system. Figure 8 In the diagram, the thick black line represents pipe connections, the thin black line represents communication lines, the left side of the blue line indicates the indoor side, the right side indicates the outdoor side, and the area below the blue line indicates the underfloor heating water pipes buried beneath the floor (e.g., underground pipe 2). Figure 8 The dual-supply system shown includes an air-source heat pump system and a water-based underfloor heating system. The air-source heat pump system has an indoor air conditioning unit and an outdoor air conditioning unit, while the water-based underfloor heating system has a buried pipe 2. The indoor air conditioning unit and the buried pipe 2 are located on the indoor side, and the outdoor air conditioning unit is located on the outdoor side. On the indoor side, an Ultra Wide Band (UWB) communication device 1 (such as millimeter-wave radar), a first temperature sensor 3, a second temperature sensor 4, and a third temperature sensor 5 are also installed. The UWB device 1 and the first temperature sensor 3 can be located on the indoor air conditioning unit, the second temperature sensor 4 can be located on the indoor wall, and the third temperature sensor 5 can be located on the buried pipe 2 on the indoor side. The UWB device 1 installed on the indoor side works by emitting high-frequency electromagnetic waves, which are reflected by objects. The received electromagnetic waves are analyzed to determine the size and trajectory of the objects. The UWB device 1 communicates with the indoor unit, sending coordinates and speed information to the indoor unit for application and judgment.

[0056] A radiation sensor 6 and an outdoor temperature sensor 7 are also installed on the outdoor side, and both can be installed on the outdoor unit of the air conditioner. The indoor and outdoor units exchange heat, while the outdoor unit exchanges heat with the buried pipe 2 (which consists of a heat exchange device and piping; the heat exchange device can change the temperature of the incoming water from cold to hot or vice versa). The indoor unit cannot exchange heat with the buried pipe 2. Figure 8It can be seen that the communication lines of the indoor unit, outdoor unit, and underground pipe 2 are interconnected and can communicate with each other. However, the pipes of the indoor unit and outdoor unit are connected, and the pipes of the outdoor unit and underground pipe 2 are connected, but the pipes of the indoor unit and underground pipe 2 are not connected.

[0057] In the solution of the present invention, the indoor ambient temperature detected by the first temperature sensor (3) at the first set height in the room where the dual-supply system is located, the indoor ambient temperature detected by the second temperature sensor (4) at the second set height in the room where the dual-supply system is located, and the indoor ambient temperature detected by the third temperature sensor (5) at the third set height in the room where the dual-supply system is located are obtained. The position parameters and speed parameters of the user detected by the millimeter-wave radar in the room where the dual-supply system is located are obtained. The outdoor ambient temperature detected by the outdoor temperature sensor (7) outside the room where the dual-supply system is located, and the outdoor solar radiation parameters detected by the thermal radiation sensor (6) outside the room where the dual-supply system is located are obtained. Then, by using the method of comprehensively judging the data collected by temperature sensors at different locations in the vertical space, the problem of the inaccurate control of the heat source output of the dual-supply system is solved, making the equipment of the dual-supply system more energy-efficient and efficient.

[0058] In some embodiments, the indoor environmental parameters of the combined cooling, heating, and power (CCHP) system include: the indoor environmental temperature at a first altitude, the indoor environmental temperature at a second altitude, and the indoor environmental temperature at a third altitude; the indoor user activity parameters of the CCHP system include: the user location parameters and the user speed parameters; and the outdoor environmental parameters of the CCHP system include: the outdoor environmental temperature and the outdoor solar radiation parameters. Specifically, the first altitude indoor environmental temperature is, for example, the upper indoor air temperature Tup; the second altitude indoor environmental temperature is, for example, the middle indoor air temperature Tmid; and the third altitude indoor environmental temperature is, for example, the lower indoor air temperature Tdown. The user location parameters are, for example, the indoor personnel location coordinates (x, y, z); the user speed parameters are, for example, the personnel movement speed v; the outdoor environmental temperature is, for example, the outdoor environmental temperature Tout; and the outdoor solar radiation parameters are, for example, the solar radiation intensity G.

[0059] In step S120, the specific process of controlling the operation mode of the combined heat and power system based on the indoor environmental parameters of the combined heat and power system, combined with the indoor user activity parameters of the combined heat and power system and / or the outdoor environmental parameters of the combined heat and power system, is described in the following exemplary description.

[0060] The following is combined with Figure 2 The flowchart shown is a schematic diagram of an embodiment of the method of the present invention for controlling the operation mode of the dual power supply system. It further illustrates the specific process of controlling the operation mode of the dual power supply system in step S120, including steps S210 to S230.

[0061] Step S210: Determine the indoor vertical temperature difference parameter of the dual-supply system based on the first height indoor ambient temperature, the second height indoor ambient temperature, and the third height indoor ambient temperature of the dual-supply system; the indoor vertical temperature difference parameter of the dual-supply system is, for example, the indoor vertical temperature difference index ΔT_w.

[0062] Step S220: Determine the user activity intensity parameter of the dual-supply system based on the user location parameter and the user speed parameter of the dual-supply system; the user activity intensity parameter of the dual-supply system is, for example, the personnel activity intensity index Iact.

[0063] Step S230: Based on the indoor vertical temperature difference parameter of the combined heat and power system, and combined with at least one of the user activity intensity parameter of the combined heat and power system, the outdoor ambient temperature of the combined heat and power system, and the outdoor solar radiation parameter of the combined heat and power system, control the operation mode of the combined heat and power system.

[0064] Preferably, the operation mode of the combined cooling, heating, and power (CCHP) system is controlled based on the indoor environmental parameters, combined with the indoor user activity parameters and / or the outdoor environmental parameters. Specifically, this includes: determining the indoor vertical temperature difference parameter of the CCHP system based on the first, second, and third altitude indoor environmental temperatures; the indoor vertical temperature difference parameter may be an indoor vertical temperature difference index ΔT_w. Determining the user activity intensity parameter of the CCHP system based on the user location and speed parameters; the user activity intensity parameter may be an activity intensity index Iact. Determining the outdoor environmental interference parameter of the CCHP system based on the outdoor environmental temperature and outdoor solar radiation parameters; the outdoor environmental interference parameter may be an environmental interference correction factor. Based on the indoor vertical temperature difference parameters of the combined heat and power system, combined with the user activity intensity parameters of the combined heat and power system and / or the outdoor environmental interference parameters of the combined heat and power system, the operation mode of the combined heat and power system is controlled.

[0065] Figure 9This is a flowchart illustrating an embodiment of a dynamic indoor thermal comfort control method for a combined cooling, heating, and power (CCHP) system based on multi-source heterogeneous data fusion. Figure 9 As shown, a method for dynamic indoor thermal comfort control of a combined heat and power (CHP) system based on multi-source heterogeneous data fusion includes:

[0066] Step 1: Power on and start the dual-supply system, then proceed to Step 2.

[0067] Step 2: Collect parameters of the dual power supply system in real time and set threshold parameters, then proceed to Step 3.

[0068] In step 2, the parameters of the dual-supply system detected in real time include: temperatures at different heights in the indoor environment, such as the upper indoor air temperature Tup, the middle indoor air temperature Tmid, and the lower indoor air temperature Tdown; the outdoor ambient temperature Tout; personnel location parameters (UWB), such as personnel location coordinates (x, y, z), personnel movement speed v, and solar radiation intensity G. The set threshold parameters include: a set temperature Tset, a first temperature threshold δ1 (e.g., 2℃) and a second temperature threshold δ2 (e.g., 0.5℃), and a speed threshold v0.

[0069] In step 2, multiple data sources are collected: After the dual-supply system is started, the upper indoor air temperature Tup is collected by the first temperature sensor 3 built into the air inlet of the indoor unit of the air conditioner (i.e., the air source heat pump system); the middle indoor air temperature Tmid is collected by the second temperature sensor 4 installed at the base of the online controller; and the lower indoor air temperature Tdown is collected by the third temperature sensor 5 attached to the floor of the water-based underfloor heating system. Simultaneously, the UWB device 1 integrated into the air conditioner (i.e., the air source heat pump system) monitors the real-time coordinates (x, y, z) of the indoor personnel and their movement speed v. The working principle of the UWB device 1 is roughly as follows: After emitting nanosecond-level pulse signals, the UWB device 1 receives the signals reflected back from objects, and determines the position and movement speed of the personnel by measuring the duration of reflections from multiple angles. All of the above are processed by the UWB device 1 and sent to the indoor unit for direct use.

[0070] Step 3: Preprocess the parameters of the dual-supply system obtained in real time to obtain the indoor vertical temperature difference index ΔT_w and the personnel activity intensity index Iact, and then proceed to step 4.

[0071] Step 4: Determine the target operating condition based on the indoor vertical temperature difference index ΔT_w and the personnel activity intensity index Iact, and compensate the set temperature Tset by combining the outdoor ambient temperature Tout and the environmental interference correction factor. Then, execute any one of steps 5, 6 and 7 respectively to control the operation mode of the dual-supply system based on the indoor vertical temperature difference parameter of the dual-supply system, combined with the user activity intensity parameter of the dual-supply system and / or the outdoor environmental interference parameter of the dual-supply system, so that the air conditioner and the underfloor heating can operate in coordination.

[0072] In the present invention, based on the indoor environmental parameters of the combined cooling, heating, and power (CCHP) system, combined with the indoor user activity parameters and / or the outdoor environmental parameters of the CCHP system, the operation mode of the CCHP system is controlled. Specifically, this is achieved by constructing a multi-dimensional sensing model that includes vertical temperature difference, activity intensity, and local heat load. By combining these factors, the air supply strategy of the air conditioning (i.e., air source heat pump system) and the output ratio of the water-based underfloor heating system are dynamically optimized. This solves the problem in related solutions where CCHP systems (such as CCHP heating systems) rely solely on single ambient temperature feedback, failing to perceive indoor vertical temperature stratification differences and local thermal comfort needs. This results in low efficiency, high energy consumption, and uneven user comfort (e.g., hot head, cold feet) between the air conditioning (i.e., air source heat pump system) and water-based underfloor heating systems. Local heat load refers to the heat accumulated in a specific room due to the combined effects of solar radiation, building insulation, and ambient temperature and humidity.

[0073] In some embodiments, step S210, determining the indoor vertical temperature difference parameter of the combined heat and power system based on the first-height indoor ambient temperature, the second-height indoor ambient temperature, and the third-height indoor ambient temperature of the combined heat and power system, includes:

[0074] Based on the first, second, and third height indoor ambient temperatures of the combined heat and power (CHP) system, the indoor vertical temperature difference index of the CHP system is calculated using the following formula, and is used as the indoor vertical temperature difference parameter of the CHP system:

[0075] K=|(T_mid-(T_down+T_up) / 2)| / ((T_up-T_down)+ε);

[0076] ΔT_w=(T_up-T_down)*(1+k1*K);

[0077] Wherein, K represents the temperature curve factor, T_up represents the indoor ambient temperature at the first height of the combined heat and power system, T_mid represents the indoor ambient temperature at the second height of the combined heat and power system, T_down represents the indoor ambient temperature at the third height of the combined heat and power system, ε represents the preset minimum value, ΔT_w represents the indoor vertical temperature difference index of the combined heat and power system, and k1 represents the preset calculation coefficient, k1 being greater than 0 and less than 1, preferably k1 being 0.2. Here, the value of k1 is between 0.1 and 0.3. The reason for k1 being 0.2 is that it is adjusted by calculating ΔT_w. ΔT_w needs to be compared with δ1 and δ2. It is more reasonable for δ1 and δ2 to be 2℃ and 0.5℃, respectively. Therefore, it is preferable to take k1 as 0.2, so that the calculated ΔT_w is more appropriate. It is used to adjust the amplification effect of nonlinear distribution on the final temperature difference index.

[0078] like Figure 9 As shown, the indoor thermal comfort dynamic control method for a combined heat and power system based on multi-source heterogeneous data fusion also includes:

[0079] In step 3, the multiple data source preprocessing includes: step 31.

[0080] Step 31: The dual-source heat pump system uses the temperatures from three data collection points to calculate the vertical temperature difference. For example, based on the upper indoor air temperature Tup, the middle indoor air temperature Tmid, and the lower indoor air temperature Tdown, the indoor vertical temperature difference can be calculated, resulting in the indoor vertical temperature difference index ΔT_w.

[0081] ΔT_w=(T_up-T_down)*(1+0.2*K) (1);

[0082] K=|(T_mid-(T_down+T_up) / 2)| / ((T_up-T_down)+ε) (2).

[0083] Where ΔT_w is the indoor vertical temperature difference index, and 0.2 represents the calculation coefficient; K is the temperature curvature factor, and ε is the minimum value to prevent the denominator from being zero.

[0084] In this invention, the indoor vertical temperature difference parameter of the combined cooling, heating, and power (CCHP) system is determined based on the first, second, and third indoor ambient temperatures at the combined cooling, heating, and power (CCHP) system. The indoor heat distribution is quantified by calculating the temperature curvature factor K and the indoor vertical temperature difference index ΔT_w, transforming the determination from a single temperature assessment to a comprehensive assessment of the entire room's thermal field. By collecting temperatures at three dimensions—the upper (Tup), middle (Tmid), and lower (Tdown) of the indoor environment—the CCHP system can calculate the indoor vertical temperature difference for targeted control, preventing the accumulation of hot or cold air in stratified zones and improving comfort.

[0085] In some implementations, the specific process of determining the user activity intensity parameter of the dual-supply system based on the user location parameter and the user speed parameter of the dual-supply system in step S220 is illustrated in the following exemplary description.

[0086] The following is combined with Figure 3 The schematic diagram shown is a flowchart of an embodiment of the method of the present invention for determining the user activity intensity parameter of the dual-supply system. It further illustrates the specific process of determining the user activity intensity parameter of the dual-supply system in step S220, including steps S310 to S340.

[0087] Step S310: Determine whether the user speed parameter of the dual-supply system is greater than a preset speed threshold and whether the change in the user position parameter of the dual-supply system within a set time period is greater than a preset change.

[0088] Step S320: If it is determined that the user speed parameter of the dual-supply system is greater than a preset speed threshold and the change in the user position parameter of the dual-supply system within a set time period is greater than a preset change, then the user status of the dual-supply system is determined to be active.

[0089] Step S330: If it is determined that the user speed parameter of the dual-supply system is greater than the preset speed threshold and the change in the user position parameter of the dual-supply system within the set time period is greater than the preset change amount, then the user state of the dual-supply system is determined to be stationary.

[0090] Step S340: The parameters used to characterize the user status of the dual-supply system as active and the parameters used to characterize the user status of the dual-supply system as inactive are used as the user activity intensity parameters of the dual-supply system; the user activity intensity parameters of the dual-supply system are, for example, the personnel activity intensity index Iact.

[0091] like Figure 9 As shown, the indoor thermal comfort dynamic control method for a combined heat and power system based on multi-source heterogeneous data fusion also includes:

[0092] In step 3, the preprocessing of multiple data sources also includes step 32.

[0093] Step 32: Based on the person's position coordinates (x, y, z) and movement speed v, determine the person's activity intensity and obtain the activity intensity index Iact: If the person's movement speed v > the speed threshold v0 and the person's position coordinates (x, y, z) change significantly, then the person's state represented by the activity intensity index Iact is considered active; otherwise, the person's state represented by the activity intensity index Iact is considered stationary. For example, a person's normal walking speed is 0.5 m / s to 1.5 m / s, the speed threshold v0 can be taken as 0.8 m / s, and a 0.5 m change in position coordinates is used as the standard.

[0094] In the present invention, the user activity intensity parameter of the dual-supply system is determined based on the user location parameter and the user speed parameter of the dual-supply system. Specifically, the static and active states of the user activity are distinguished based on the personnel location coordinates (x, y, z) and the personnel movement speed v, so as to ensure that the most accurate compensation is provided at the moment when comfort is most needed, thereby improving indoor comfort.

[0095] In some implementations, step S230 involves controlling the operation mode of the combined heat and power system based on the indoor vertical temperature difference parameter of the combined heat and power system, combined with at least one of the user activity intensity parameter of the combined heat and power system, the outdoor ambient temperature of the combined heat and power system, and the outdoor solar radiation parameter of the combined heat and power system. This includes controlling the operation mode of the combined heat and power system to operate according to a preset first operation mode.

[0096] The following is combined Figure 4 The flowchart shown is a schematic diagram of an embodiment of the method of the present invention in which the operation mode of the dual power supply system is controlled to operate according to a preset first operation mode. The specific process of controlling the operation mode of the dual power supply system to operate according to the preset first operation mode in step S230 is further explained, including steps S410 to S430.

[0097] Step S410: If it is determined that the indoor vertical temperature difference parameter of the dual-supply system is greater than the first preset temperature difference parameter, and the user status of the dual-supply system characterized by the user activity intensity parameter is a static state, then the operation mode of the dual-supply system is controlled to be the preset first operation mode; wherein, the preset first operation mode is the convection compensation priority mode; the first preset temperature difference parameter is such as the first temperature threshold δ1.

[0098] Step S420: In the preset first operating mode, control the compressor in the air conditioner to operate at a first preset operating frequency, control the air outlet direction of the indoor unit in the air conditioner to be horizontal, control the fan speed of the indoor unit to be a preset low speed, and control the water pump in the underfloor heating system to operate at a first preset speed. Specifically, control the air guide direction of the air deflector of the indoor unit in the air conditioner to be horizontal, control the fan speed of the indoor fan to be a preset high speed, control the air outlet grille of the indoor unit to sweep air up and down at a first preset sweeping frequency, and control the water pump of the underfloor heating system to operate at a first preset speed. Wherein, the compressor operating at the first preset operating frequency is equivalent to the compressor operating at a low frequency, the fan speed of the indoor fan is a preset low speed (e.g., the indoor fan is outleting air at a low speed), and the water pump operating at the first preset speed is equivalent to the water pump running at a low speed. The main issue addressed here is the problem of the head being hot and the feet being cold (i.e., the upper part being hot and the lower part being cold). Therefore, the air guide plate is kept horizontal, the windshield is set to a low setting, and there is no need for air sweeping. This prevents the air above the air conditioner from rising rapidly, reduces the temperature difference between the upper and lower parts of the room, and achieves a suitable temperature.

[0099] Step S430: After the first set time, return to the previous step to re-control the operation mode of the combined heat and power system based on the indoor environmental parameters of the combined heat and power system, combined with the indoor user activity parameters of the combined heat and power system and / or the outdoor environmental parameters of the combined heat and power system.

[0100] like Figure 9 As shown, the indoor thermal comfort dynamic control method for a combined heat and power system based on multi-source heterogeneous data fusion also includes:

[0101] Step 5: If the indoor vertical temperature difference index ΔT_w > the first temperature threshold δ1 and the personnel activity intensity index Iact is in a static state, it is determined that there is a serious head-hot-feet-cold phenomenon in the current indoor environment, and the convection compensation priority mode is entered to execute step 51.

[0102] Step 51: The compressor in the outdoor unit of the air conditioner operates at a low to medium frequency. The air outlet blades of the indoor fan in the indoor unit of the air conditioner are adjusted to a horizontal position and the powerful air outlet is turned on. The water pump of the water-based underfloor heating system runs at a low speed. After the set time, return to step 2.

[0103] In the scheme of the present invention, in the convection compensation priority mode, the air conditioner (i.e., air source heat pump system) compressor is controlled to operate at low and medium frequency, and the air outlet blades are adjusted to a horizontal position or the strong air outlet mode is turned on to increase the air volume to force convection and mix the upper and lower layers of air; at the same time, the water underfloor heating pump is controlled to operate at low speed to keep the underfloor heating water supply temperature at a low level (e.g., 35°C) to provide only the basic ground temperature and prevent the upper part from overheating.

[0104] In the present invention, based on the indoor vertical temperature difference parameter of the combined heat and power system, and combined with at least one of the user activity intensity parameter, outdoor ambient temperature, and outdoor solar radiation parameter of the combined heat and power system, the operation mode of the combined heat and power system is controlled. This includes controlling the operation mode of the combined heat and power system to operate according to a preset first operation mode. An adaptive airflow compensation mechanism is employed: when a large vertical temperature difference is detected and the person is stationary, the air deflector of the air conditioner (i.e., the air source heat pump system) is automatically adjusted to a horizontal airflow or low-frequency oscillation mode to promote air mixing between upper and lower layers, rather than simply increasing heating capacity and thus increasing energy consumption. This solves the problems of delayed response from a single heat source and unreasonable airflow organization leading to localized overcooling or overheating. It achieves the effect of using the air conditioner (i.e., the air source heat pump system) to quickly adjust airflow organization to equalize room temperature and using underfloor heating to provide basic radiant heat to stabilize the base temperature, thereby achieving a constant temperature throughout the house without dead zones and improving overall comfort.

[0105] In some implementations, step S230, based on the indoor vertical temperature difference parameter of the combined heat and power system, and combined with at least one of the user activity intensity parameter of the combined heat and power system, the outdoor ambient temperature of the combined heat and power system, and the outdoor solar radiation parameter of the combined heat and power system, controls the operation mode of the combined heat and power system, and further includes: controlling the operation mode of the combined heat and power system to operate according to a preset second operation mode.

[0106] The following is combined Figure 5 The flowchart shown is a schematic diagram of an embodiment of the method of the present invention in which the operation mode of the dual power supply system is controlled to operate according to a preset second operation mode. The specific process of controlling the operation mode of the dual power supply system to operate according to the preset second operation mode in step S230 is further explained, including steps S510 to S540.

[0107] Step S510: Determine the average value of the first-height indoor ambient temperature, the second-height indoor ambient temperature, and the third-height indoor ambient temperature of the combined heat and power system as the average indoor temperature of the combined heat and power system; wherein, the first-height indoor ambient temperature of the combined heat and power system is, for example, the upper indoor air temperature Tup; the second-height indoor ambient temperature of the combined heat and power system is, for example, the middle indoor air temperature Tmid; and the third-height indoor ambient temperature of the combined heat and power system is, for example, the lower indoor air temperature Tdown.

[0108] Step S520: If it is determined that the indoor vertical temperature difference parameter of the combined heat and power system is less than or equal to the second preset temperature difference parameter, and the absolute value of the temperature difference between the indoor average temperature of the combined heat and power system and the set temperature of the combined heat and power system is less than the preset temperature difference threshold, then the operating mode of the combined heat and power system is controlled to be the preset second operating mode; the second preset temperature difference parameter is less than the first preset temperature difference parameter; wherein, the preset second operating mode is a convection compensation priority mode; the first preset temperature difference parameter is such as the first temperature threshold δ1, the second preset temperature difference parameter is such as the second temperature threshold δ2; the set temperature of the combined heat and power system is such as the set temperature Tset.

[0109] Step S530: In the preset second operating mode, control the compressor in the air conditioner to operate at a second preset operating frequency, control the water supply mode of the underfloor heating to a preset constant temperature water supply mode, and adjust the set temperature of the dual-supply system according to the outdoor ambient temperature of the dual-supply system and / or the outdoor solar radiation parameters of the dual-supply system; the second preset operating frequency is less than the first preset operating frequency; the compressor in the air conditioner operates at the second preset operating frequency, such as the compressor operating at a very low frequency, and the water supply mode of the underfloor heating is a preset constant temperature water supply mode, such as the underfloor heating maintaining a constant temperature water supply.

[0110] Step S540: After the second set time, return to the previous step to re-control the operation mode of the combined heat and power system based on the indoor environmental parameters of the combined heat and power system, combined with the indoor user activity parameters of the combined heat and power system and / or the outdoor environmental parameters of the combined heat and power system.

[0111] In the solution of this invention, based on the indoor vertical temperature difference parameter of the dual-source heat pump system, and combined with at least one of the user activity intensity parameter of the dual-source heat pump system, the outdoor ambient temperature of the dual-source heat pump system, and the outdoor solar radiation parameter of the dual-source heat pump system, the operation mode of the dual-source heat pump system is controlled, including: controlling the operation mode of the dual-source heat pump system to operate according to a preset second operation mode; in this way, through the combined action of the air source heat pump system and the water underfloor heating system, combined with the data collected by different types of sensors (temperature, UWB, light intensity) to jointly determine, the problem of local overheating or overcooling caused by a single heat source in related solutions is solved, achieving the effect of constant temperature throughout the house without dead corners and improving comfort.

[0112] In some embodiments, step S530 involves adjusting the set temperature of the combined heat and power system based on the outdoor ambient temperature and / or the outdoor solar radiation parameters of the combined heat and power system, including any of the following situations where the set temperature of the combined heat and power system is adjusted.

[0113] The first method for adjusting the set temperature of the combined cooling, heating, and power (CCHP) system is as follows: If the current time is determined to be within a first preset time interval, the set temperature of the CCHP system is adjusted according to the outdoor ambient temperature: The set temperature is adjusted in the opposite direction based on the difference between the outdoor ambient temperature and a preset temperature reference value. For example, if the outdoor ambient temperature exceeds the preset temperature reference value, the set temperature is decreased according to a preset correspondence based on the amount by which the outdoor ambient temperature exceeds the preset temperature reference value; if the outdoor ambient temperature does not reach the preset temperature reference value, the set temperature is increased according to a preset first correspondence based on the amount by which the outdoor ambient temperature does not reach the preset temperature reference value.

[0114] The second method for adjusting the set temperature of the combined cooling, heating, and power (CCHP) system is as follows: If the current time is determined to be within a second preset time interval, the set temperature of the CCHP system is adjusted according to its outdoor solar radiation parameters. Specifically, the set temperature is adjusted in the opposite direction based on the difference between the outdoor solar radiation parameters and a preset radiation reference value. For example, if the outdoor solar radiation parameters exceed the preset radiation reference value, the set temperature is lowered according to a preset correspondence based on the amount by which the outdoor solar radiation parameters exceed the preset radiation reference value; conversely, if the outdoor solar radiation parameters do not reach the preset radiation reference value, the set temperature is increased according to a preset second correspondence based on the amount by which the outdoor solar radiation parameters do not reach the preset radiation reference value.

[0115] like Figure 9 As shown, the indoor thermal comfort dynamic control method for a combined heat and power system based on multi-source heterogeneous data fusion also includes:

[0116] Step 6: If the indoor vertical temperature difference index ΔT_w ≤ the second temperature threshold δ2 and the indoor average temperature is close to the set temperature Tset, then enter the radiation maintenance mode to execute step 61.

[0117] Step 61: The compressor in the outdoor unit of the air conditioner operates at an extremely low frequency, the water-based underfloor heating system maintains a constant water supply, the set temperature Tset is reasonably compensated according to the outdoor ambient temperature Tout and the solar radiation intensity G, and after setting the time, return to step 2.

[0118] Among them, the indoor vertical temperature difference index ΔT_w ≤ the second temperature threshold δ2 and the indoor average temperature is close to the set temperature Tset, indicating that the indoor temperature is relatively suitable. The outdoor unit operates at extremely low frequency, which enables the indoor unit to blow out some cold or hot air. The water underfloor heating system constantly heats or cools the water, keeping the water temperature constant as it flows in the buried pipes. The two work together, namely, the compressor in the outdoor unit of the air conditioner operates at extremely low frequency and the water underfloor heating system maintains a constant water supply, thus keeping the temperature constant.

[0119] Outdoor ambient temperature Tout and solar radiation intensity G were collected as environmental disturbance correction factors. The indoor temperature difference ΔT relative to the outdoor temperature is directly proportional to the solar radiation intensity G, which varies at different times and under different weather conditions.

It refers to the size of the window area. It is based on the heat flux density and temperature data of the entire building obtained from heat flux meters and temperature sensors. It is obtained by using the heat flux density and / or temperature data of the entire building. . G is the room's area. G is the solar radiation intensity.

[0122] The set temperature Tset is adjusted based on the outdoor ambient temperature Tout and the environmental interference correction factor. During use, Tset can be adjusted according to the outdoor ambient temperature during the day; at night, when the outdoor temperature is lower but indoor heat has not dissipated, Tset needs to be adjusted according to the environmental interference correction factor. For example, adjust the set temperature Tset according to the outdoor ambient temperature during the day, and adjust it according to the environmental interference correction factor at night. For instance, in heating mode, with the outdoor ambient temperature Tout as a baseline of 25°C, the set temperature Tset decreases by 0.1°C for every degree the outdoor ambient temperature Tout increases. Similarly, for the environmental interference correction factor, if the environmental interference correction factor is higher than the baseline value by a certain amount, the set temperature Tset decreases by that amount; if the environmental interference correction factor is lower than the baseline value by a certain amount, the set temperature Tset increases by that amount.

[0123] In this invention, static environmental data, such as the temperatures of the upper, middle, and lower floors of an indoor space, are linked to the dynamic human metabolic rate. Different activity intensity indices (Iact) correspond to different optimal comfort temperatures (e.g., a preference for lower temperatures during exercise), and the target set temperature (Tset) is automatically fine-tuned. When the activity intensity index (Iact) is determined to be in an active state, the set temperature (Tset) is automatically adjusted down by 1 degree to ensure that the body generates heat during active movement, thus lowering the indoor temperature appropriately.

[0124] In the solution of this invention, under the radiation maintenance mode: the compressor of the air conditioner (i.e., the air source heat pump system) operates at a very low frequency, and only the fan is kept running at a low speed to assist air circulation; the underfloor heating maintains a constant temperature water supply, and relies on radiant heat to maintain a stable indoor temperature, thus achieving quiet and energy-saving operation.

[0125] In some implementations, step S230, based on the indoor vertical temperature difference parameter of the combined heat and power system, and combined with at least one of the user activity intensity parameter of the combined heat and power system, the outdoor ambient temperature of the combined heat and power system, and the outdoor solar radiation parameter of the combined heat and power system, controls the operation mode of the combined heat and power system, and further includes: controlling the operation mode of the combined heat and power system to operate according to a preset third operation mode.

[0126] The following is combined Figure 6 The flowchart shown is a schematic diagram of an embodiment of the method of the present invention in which the operation mode of the dual power supply system is controlled to operate according to a preset third operation mode. The specific process of controlling the operation mode of the dual power supply system to operate according to the preset third operation mode in step S230 is further explained, including steps S610 to S640.

[0127] Step S610: If it is determined that the indoor vertical temperature difference parameter of the combined heat and power system is less than or equal to the second preset temperature difference parameter, the indoor average temperature of the combined heat and power system has not reached the set temperature of the combined heat and power system, and the absolute value of the temperature difference between the indoor average temperature of the combined heat and power system and the set temperature of the combined heat and power system is greater than or equal to the preset temperature difference threshold, then the operating mode of the combined heat and power system is controlled to be the preset third operating mode; the second preset temperature difference parameter is less than the first preset temperature difference parameter; wherein, the preset second operating mode is a convection compensation priority mode; the first preset temperature difference parameter is such as the first temperature threshold δ1, the second preset temperature difference parameter is such as the second temperature threshold δ2; the set temperature of the combined heat and power system is such as the set temperature Tset.

[0128] Step S620: In the preset third operating mode, in the heating mode, control the air outlet direction of the indoor unit of the air conditioner to the preset direction of avoiding people, control the electric auxiliary heating device of the indoor unit of the air conditioner to turn on, and control the heating method of the floor heating to the preset method of accelerating the floor temperature rise.

[0129] Step S630: After the third set time, adjust the heating ratio of the air conditioner and the underfloor heating according to the indoor vertical temperature difference parameter of the dual-supply system to maintain the indoor vertical temperature difference parameter of the dual-supply system less than or equal to the second preset temperature difference parameter.

[0130] Step S640, after the fourth set time, return to the previous step to re-control the operation mode of the combined heat and power system based on the indoor environmental parameters of the combined heat and power system, combined with the indoor user activity parameters of the combined heat and power system and / or the outdoor environmental parameters of the combined heat and power system.

[0131] In the present invention, based on the indoor vertical temperature difference parameter of the combined heat and power system, and combined with at least one of the user activity intensity parameter, outdoor ambient temperature, and outdoor solar radiation parameter of the combined heat and power system, the operation mode of the combined heat and power system is controlled, including: controlling the operation mode of the combined heat and power system to operate according to a preset third operation mode; thus, a multi-dimensional thermal comfort perception model is adopted: integrating the return air temperature of the indoor unit of the air conditioner (i.e., air source heat pump system), the ground temperature at the wired controller, and the personnel activity status parameters detected by millimeter-wave radar, to construct a comprehensive evaluation system including the vertical temperature difference index and the personnel heat load index, so as to combine the vertical temperature difference, personnel activity intensity, and local heat load to dynamically optimize the air supply strategy of the air conditioner (i.e., air source heat pump system) and the output ratio of the water underfloor heating system, improve the synergistic efficiency of the air conditioner (i.e., air source heat pump system) and the water underfloor heating system, reduce energy consumption, and improve comfort.

[0132] In some implementations, in step S630, the heating ratio of the air conditioner and the underfloor heating is adjusted according to the indoor vertical temperature difference parameter of the dual-supply system to maintain the indoor vertical temperature difference parameter of the dual-supply system being less than or equal to a second preset temperature difference parameter, including any of the following situations where the heating ratio of the air conditioner and the underfloor heating is adjusted.

[0133] The first method for adjusting the heating ratio of the air conditioner and the underfloor heating is as follows: If it is determined that the indoor vertical temperature difference parameter of the dual-supply system is less than 0, then the heating ratio of the air conditioner is increased and the heating ratio of the underfloor heating is decreased, so as to maintain the indoor vertical temperature difference parameter of the dual-supply system less than or equal to the second preset temperature difference parameter.

[0134] The second method for adjusting the heating ratio of the air conditioner and the underfloor heating is as follows: If it is determined that the indoor vertical temperature difference parameter of the dual-supply system is greater than 0, then the heating ratio of the air conditioner is reduced and the heating ratio of the underfloor heating is increased, so as to maintain the indoor vertical temperature difference parameter of the dual-supply system less than or equal to the second preset temperature difference parameter.

[0135] like Figure 9 As shown, the indoor thermal comfort dynamic control method for a combined heat and power system based on multi-source heterogeneous data fusion also includes:

[0136] Step 7: If the indoor vertical temperature difference index ΔT_w ≤ the second temperature threshold δ2 and the indoor average temperature is lower than the set temperature Tset by a certain range, then the current indoor environment is determined to be a low-temperature environment, and the mixed heating mode is entered to execute step 71.

[0137] Step 71: The air conditioner directs airflow away from people and activates the electric auxiliary heating function. The water-based underfloor heating system accelerates the floor's heat storage and temperature rise. Based on the dynamic changes in the indoor vertical temperature difference index ΔT_w, the heating ratio of the air conditioner and / or the water-based underfloor heating system is adjusted. For example, when the temperature is lower at higher elevations, the air conditioner's heating capacity is increased; when the temperature is lower at lower elevations, the underfloor heating capacity is increased to reduce the temperature difference between higher and lower elevations. After setting a time, return to Step 2. This indicates that the temperature is low, requiring both air conditioner heat pump heating and electric heating to quickly raise the indoor temperature. Activating the electric heating is for faster temperature rise. Here, the opening of the air conditioner's electronic expansion valve is controlled to further control the air conditioner's heating capacity, and the temperature and flow rate of the water from the water-based underfloor heating system are controlled to accelerate heating.

[0138] In the solution of this invention, under the hybrid heating mode: the air conditioner (i.e., the air source heat pump system) and the water-based underfloor heating system operate simultaneously. The air conditioner (i.e., the air source heat pump system) directs airflow to avoid people, preventing cold or hot air from blowing directly on them; the underfloor heating system raises the water supply temperature to a comfortable range (e.g., 40℃~45℃), accelerating the floor's heat storage and temperature rise. At this time, the dual-supply system adjusts the ratio of the air conditioner (i.e., the air source heat pump system) fan speed to the underfloor heating flow rate in real time according to the dynamic changes of the indoor vertical temperature difference index ΔT_w, ensuring that the indoor vertical temperature difference index ΔT_w gradually converges to within the second temperature threshold δ2. For example, in the convection compensation priority mode, the upper temperature is high and the lower temperature is low, so the underfloor heating water outlet temperature and flow rate need to be high. At this time, the lower temperature rises, and the fan speed is reduced so that the upper temperature no longer rises rapidly but is maintained. In the mixed heating mode, the underfloor heating water outlet temperature and flow rate are high, and the fan speed also needs to be increased to heat the entire room quickly and quickly approach Tset. In the radiant maintenance mode, the water outlet temperature, flow rate, and fan speed are slowly adjusted to maintain the temperature.

[0139] In this invention, an asymmetric collaborative control strategy is adopted: three operating conditions are defined: convection-dominated, radiation-dominated, and hybrid equilibrium. Based on the vertical temperature difference threshold and the intensity of human activity, the weights of the air conditioner (i.e., air source heat pump system) fan speed / air guide angle and the water supply temperature of the underfloor heating system are dynamically allocated to avoid conflicts between heat and cold sources. This solves the technical problem in related solutions where dual-supply systems cannot quantify the impact of vertical temperature gradients on comfort. It can accurately match the output ratio of heat and cold sources based on the physiological characteristics of warm feet and cool head, eliminating the energy-inefficient drawbacks caused by vertical temperature differences.

[0140] In this invention, the return air temperature of the indoor unit of the air conditioner (i.e., air source heat pump system), the floor temperature at the wired controller, and the personnel activity status parameters detected by millimeter-wave radar are integrated to construct a comprehensive evaluation system that includes a vertical temperature difference index and a personnel heat load index. Three operating conditions are defined: convection-dominated, radiation-dominated, and mixed equilibrium. Based on the vertical temperature difference threshold and the intensity of personnel activity, the weights of the air conditioner (i.e., air source heat pump system) fan speed or air deflector angle and the water supply temperature of the underfloor heating system are dynamically allocated (e.g., prioritizing air conditioning or underfloor heating heating) to avoid conflicts between heat and cold sources. When an excessively large vertical temperature difference is detected and personnel are stationary, the air conditioner (i.e., air source heat pump system) air deflector is automatically adjusted to horizontal airflow, promoting air mixing between upper and lower levels and improving comfort, rather than simply increasing heating capacity and energy consumption.

[0141] The existing solutions primarily target ordinary split-type or multi-split air conditioning systems (i.e., air source heat pump systems); while the solution of this invention is specifically designed for dual-supply systems combining air source heat pump systems and water-based underfloor heating systems. Existing solutions only derive a single result from the entire algorithm model, emphasizing the uniqueness of the algorithm itself; while the solution of this invention embodies the dynamic and precise adjustment of the air source heat pump system and water-based underfloor heating system based on data collected from vertical temperature difference, human activity, and outdoor weather factors. Existing solutions mainly improve local comfort by adjusting air guides and setting temperature compensation values ​​based on the horizontal or oblique temperature difference between the installation height of the air conditioner (i.e., the air source heat pump system) and the target position of the human body, representing the adjustment of a single device; while the solution of this invention does not emphasize the specific adjustment method of a single device, but rather the coordinated control of the air source heat pump system and water-based underfloor heating system after collecting parameters.

[0142] In some embodiments, the control method for the dual-supply system of the present invention further includes at least one of the following additional control processes: a first additional control process, a second additional control process, and a third additional control process.

[0143] The first additional control process, which prioritizes the operation of the air conditioner after the dual-supply system is started, is as follows:

[0144] After the dual-supply system is started, the indoor fan of the air conditioner is controlled to operate at the preset maximum air volume and in the preset automatic air sweep mode; after the fifth preset time, while the dual-supply system is running, the indoor environmental parameters of the dual-supply system, the indoor user activity parameters of the dual-supply system, and the outdoor environmental parameters of the dual-supply system are obtained; wherein, the first preset time is, for example, 3 minutes.

[0145] In this invention, differentiated collaborative control is implemented for the air conditioning (i.e., air source heat pump system) and the water-based underfloor heating system: After the equipment is turned on and enters 3D mode (i.e., both the air conditioning (i.e., air source heat pump system) and the water-based underfloor heating system are turned on), the air conditioning (i.e., air source heat pump system) first runs automatic air sweep + maximum airflow for 3 minutes to fully mix the indoor air, ensuring the readiness of data collection and avoiding interference from accidental factors. Then, based on the judgment after step 4, it enters which operating mode, determines the target operating condition based on the indoor vertical temperature difference index ΔT_w and the occupant activity intensity index Iact, and intelligently allocates the workload of the air conditioning (i.e., air source heat pump system) and the underfloor heating system, improving the collaborative efficiency of the air conditioning (i.e., air source heat pump system) and the water-based underfloor heating system, reducing energy consumption and improving comfort.

[0146] And / or, a second additional control process for distinguishing between manned and unmanned areas during the operation of the combined heat and power system is as follows:

[0147] When the dual-supply system is in operation, if it is determined that there are no users in the current area, the air conditioner is turned off and the water supply of the underfloor heating is reduced; if it is determined that there are users in the current area, the air conditioner and the underfloor heating are controlled to operate normally.

[0148] In some alternative embodiments, fine-grained zoning control is based on visual assistance. Building upon the above embodiments, a camera, binocular vision, or time-of-flight (TOF) depth camera is introduced as a third sensing source. The dual-supply system uses image recognition algorithms to distinguish different functional areas within the room (such as rest areas, reading areas, and corridors). The UWB device 1 can be replaced by a privacy-protecting camera to more intuitively capture indoor human activity. In the rest area, the fan speed is reduced to avoid direct cold airflow, and the temperature is appropriately increased (less heat is generated during sleep). In the reading area, the fan speed is reduced to avoid interference, and the temperature is appropriately lowered in the activity area. If an unoccupied area is detected (such as the living room corridor), even if there is a slight temperature difference in that area, the dual-supply system automatically cuts off the corresponding air conditioning (i.e., air source heat pump system) indoor unit or lowers the underfloor heating circuit valve, focusing heating or cooling only on occupied areas (such as the sofa area), which improves indoor comfort and reduces energy consumption.

[0149] And / or, a third additional control process, which combines the control of outdoor solar radiation intensity during the operation of the combined heat and power system, is as follows:

[0150] When the dual-supply system is operating, if it is determined that the outdoor solar radiation intensity of the dual-supply system is greater than the set radiation intensity threshold and the curtains in the room where the dual-supply system is located are open, then the set temperature of the dual-supply system is lowered; when the dual-supply system is not operating, if it is determined that the outdoor solar radiation intensity of the dual-supply system is less than or equal to the set radiation intensity threshold and / or the curtains in the room where the dual-supply system is located are closed, then the dual-supply system is turned on before the user's predetermined opening time to pre-adjust the indoor ambient temperature of the dual-supply system.

[0151] In some alternative embodiments, visually-assisted refined zoning control, further combined with curtain opening / closing status sensors, allows the dual-supply system to automatically reduce the target temperature of the air conditioning (i.e., air-source heat pump system) or preheat or precool the floor if direct sunlight is detected entering the room. This utilizes the building's thermal inertia to offset solar radiation heat gain, achieving more precise predictive control, which improves indoor comfort and reduces energy consumption. Water-based underfloor heating not only provides hot water but can also be extended to provide cooling water; heating and cooling can be activated in advance, whether the water is directly entering the room or not, to prevent the indoor temperature from becoming too low or too high.

[0152] The technical solution of this embodiment, targeting a dual-supply system (air source heat pump system) and underfloor heating (water-based underfloor heating system), acquires indoor environmental parameters, indoor user activity parameters, and outdoor environmental parameters of the dual-supply system during operation. Based on the indoor environmental parameters, combined with the indoor user activity parameters and / or the outdoor environmental parameters, the operating mode of the dual-supply system is controlled, such as adjusting the air outlet mode of the air conditioner and the output mode of the underfloor heating. Thus, by combining indoor environmental parameters (such as indoor vertical temperature difference), indoor user activity parameters (such as activity intensity), and outdoor environmental parameters (such as outdoor temperature and solar radiation intensity), the operating mode of the dual-supply system is adjusted, improving the synergistic efficiency of air conditioning and underfloor heating, reducing energy consumption, and improving comfort. This dual-supply system is an energy-saving air conditioning system.

[0153] Specifically, in the solution of this invention, for a dual-supply system with air conditioning (i.e., an air source heat pump system) and underfloor heating (i.e., a water-based underfloor heating system), after the dual-supply system is powered on and started, the indoor fan of the air conditioner is controlled to automatically sweep air at maximum airflow for a certain period of time (e.g., 3 minutes) to ensure sufficient mixing of indoor air. Then, the operating parameters of the dual-supply system are obtained, specifically including: obtaining the temperature at different indoor heights (e.g., the upper indoor air temperature Tup obtained from the indoor unit's air inlet, the middle indoor air temperature Tmid obtained from the base of the wired controller, and the lower indoor air temperature Tdown obtained from the underfloor heating system), based on millimeter-wave radar. Based on the indoor occupants' location coordinates (x, y, z) and movement speed v, the outdoor ambient temperature Tout and outdoor solar radiation parameter G are obtained. The indoor vertical temperature difference (ΔT_w) is determined based on the upper indoor air temperature Tup, the middle indoor air temperature Tmid, and the lower indoor air temperature Tdown. The activity intensity (Iact) is determined based on the occupants' location coordinates (x, y, z) and movement speed v. An environmental interference correction factor (Iact) is determined based on the outdoor ambient temperature Tout and outdoor solar radiation parameter G. Finally, based on the indoor vertical temperature difference index ΔT_w and combined with the human... The activity intensity index Iact and the set temperature Tset are used to adjust the operating mode of the combined heat and power system (such as convection compensation priority mode, radiation maintenance mode, and mixed heating mode). Specifically, if the indoor vertical temperature difference index ΔT_w > the first temperature threshold δ1 and the activity intensity index Iact is at rest, then the operating mode of the combined heat and power system is adjusted to convection compensation priority mode: the compressor in the air conditioner is adjusted to operate at a low to medium frequency; the air outlet direction of the indoor fan in the air conditioner is adjusted to horizontal, the fan speed is adjusted to high, and the fan sweeping mode is adjusted to low-frequency up-and-down sweeping; the water pump in the underfloor heating system is adjusted to run at low speed; after a set time, the system returns to normal operation. Reacquire the operating parameters of the dual-supply system; if the indoor vertical temperature difference index ΔT_w ≤ the second temperature threshold δ2, and the difference between the indoor average temperature (i.e., the average temperature of the upper indoor air temperature Tup, the middle indoor air temperature Tmid, and the lower indoor air temperature Tdown) and the set temperature Tset is within the set difference range, then adjust the operating mode of the dual-supply system to radiation maintenance mode: the compressor in the air conditioner operates at an extremely low frequency, the water underfloor heating system maintains a constant temperature water supply, and the set temperature Tset is adjusted according to the outdoor ambient temperature Tout and the environmental interference correction factor. After the set time, return to reacquire the operating parameters of the dual-supply system.If the indoor vertical temperature difference index ΔT_w ≤ the second temperature threshold δ2, and the indoor average temperature is lower than the set temperature Tset by a certain range, the operating mode of the combined cooling, heating, and air conditioning system is adjusted to a mixed heating mode: the air outlet direction of the air conditioner's indoor fan is adjusted to directional airflow away from people and heated airflow is supplied; the water-based underfloor heating system accelerates heat storage; and the heating ratio of the air conditioner and water-based underfloor heating system is adjusted according to the indoor vertical temperature difference index ΔT_w to reduce the indoor vertical temperature difference. After a set time, the system returns to retrieve the operating parameters of the combined cooling, heating, and air conditioning system. Thus, by combining the indoor vertical temperature difference, the intensity of human activity, the outdoor ambient temperature, and the intensity of solar radiation, the operating mode of the combined cooling, heating, and air conditioning system is adjusted to improve the synergistic efficiency of air conditioning and underfloor heating, reduce energy consumption, and improve comfort. This combined cooling, heating, and air conditioning system is an energy-saving air conditioning system.
