[0002] As the concepts of comfortable living and integrated heating and cooling gradually gain popularity, "underfloor heating and air conditioning" are becoming increasingly popular among ordinary consumers. Currently, in addition to air conditioning and hot water production functions, indoor heat pump systems are also increasingly demanding heating from terminal types such as underfloor heating and radiators.
[0003] However, because the water circuit of the indoor heat pump system is relatively long, and there is a need to extend the water circuit when multiple units are working together, the temperature control of the underfloor heating is not precise, and the temperature difference in different parts of the underfloor heating fluctuates greatly. Summary of the Invention
[0004] Therefore, the present invention provides a heat pump floor heating temperature control method and its temperature control device, a heat pump floor heating system, and a readable storage medium, which achieves the purpose of constant temperature in the floor heating system by controlling the temperature of different locations of the floor heating system.
[0005] Therefore, the first objective of this invention is to provide a heat pump floor heating temperature control method.
[0006] The second objective is to provide a heat pump floor heating temperature control device;
[0007] The third objective is to provide a heat pump floor heating system;
[0008] The fourth objective is to provide a readable storage medium;
[0009] To achieve the first objective of this invention, this invention provides a heat pump underfloor heating temperature control method, the method comprising: collecting the real-time temperature T of the underfloor heating water pipes in at least two areas of the underfloor heating room. R1 ......T Rn According to the real-time temperature T R1 ...T Rn Determine the target temperature T in the room with underfloor heating. 目标 According to the target temperature T 目标 With real-time temperature T R1 ......T Rn Determine the temperature difference ΔT between at least two regions. R1-目标 ......△T Rn-目标 Based on the temperature difference ΔT R1-目标 ......△T Rn-目标 The regulating valves control the underfloor heating water circuits in at least two areas respectively.
[0010] Compared with existing technologies, the technical effects achieved by this solution are as follows: This application determines the target temperature and temperature difference within the underfloor heating room by real-time acquisition of the temperature of the underfloor heating water pipes in each area, and then controls the regulating valves of the underfloor heating water circuits in each area based on the temperature difference. This temperature control method effectively ensures consistent temperature across all areas of the underfloor heating room, avoiding large temperature fluctuations in different locations, guaranteeing the stability of water and room temperature control, preventing repeated on / off cycles due to large water temperature fluctuations, improving user comfort, and facilitating more accurate water temperature readings, thus improving system control efficiency, reliability, and floor temperature control precision, ultimately achieving a constant temperature for the underfloor heating system.
[0011] In one technical solution of the present invention, based on the real-time temperature T R1 ...T Rn Determine the target temperature T in the room with underfloor heating. 目标 In the steps,
[0012] Target temperature T 目标 ;
[0013] Where n represents the number of zones in a room with underfloor heating.
[0014] Compared with existing technologies, the technical effects achieved by this technical solution are: through real-time temperature T R1 ...T Rn Determine the target temperature T in the room with underfloor heating. 目标 In the process, since the water pipes in a room with underfloor heating are relatively short, the difference between different areas is small. Therefore, averaging is a more reliable and stable method because it is related to every data point and reflects the most complete information. It is the overall average temperature of the entire room with underfloor heating, which is more scientific.
[0015] In one technical solution of the present invention, based on the temperature difference ΔT R1-目标 ......△T Rn-目标 The regulating valves that control the underfloor heating water circuits in at least two areas respectively include: determining the temperature difference ΔT for each area. R1-目标 ......△T Rn-目标 If the value exceeds the first set value, the regulating valve of the underfloor heating water circuit in the current area will be controlled based on the judgment result.
[0016] Compared with existing technologies, the technical effects achieved by this solution are as follows: it automatically judges the underfloor heating temperature by the difference and determines whether the temperature difference exceeds a first set value. Based on the judgment result, it controls the regulating valve of the underfloor heating water circuit in the current area, thereby improving the heating efficiency of the underfloor heating system and saving energy and protecting the environment. It can also intelligently adjust the temperature according to different temperature zones, avoiding the problem of large temperature fluctuations in different locations of the underfloor heating system in the past.
[0017] In one technical solution of the present invention, controlling the regulating valve of the underfloor heating water circuit in the current area according to the judgment result includes: if the judgment result is no more than a first set value, then the regulating valve of the underfloor heating water circuit in the current area maintains the current opening degree; if the judgment result is more than the first set value, then controlling the opening degree of the regulating valve of the underfloor heating water circuit in the current area changes.
[0018] Compared with existing technologies, the technical effects achieved by this solution are as follows: By setting a first set value, if the judgment result is no more than the first set value, the regulating valve of the underfloor heating water circuit in the current area will maintain its current opening; if the judgment result is more than the first set value, the opening of the regulating valve of the underfloor heating water circuit in the current area will be controlled to change. The regulating valve of the underfloor heating water circuit can intelligently adjust the temperature according to different temperature zones to make the temperature control more precise. Moreover, the current area refers to one area in the underfloor heating water circuit. This application selects one temperature-controlled section for temperature control operation without increasing the overall heating demand of the heat pump system, thus saving more energy.
[0019] In one technical solution of the present invention, controlling the change in the opening degree of the regulating valve of the underfloor heating water circuit in the current area further includes: determining the temperature of the underfloor heating water circuit in the current area. If the value exceeds the second set value and the second set value is greater than the first set value, then adjust the opening of the regulating valve of the underfloor heating water circuit in the current area; if the value exceeds the second set value, then adjust the opening of the regulating valve of the underfloor heating water circuit in the current area to the maximum.
[0020] Compared with existing technologies, the technical effect achieved by adopting this technical solution is: when determining the temperature of the underfloor heating water circuit in the current area... If the temperature does not exceed the second set value, adjust the opening of the regulating valve in the current area's underfloor heating water circuit; if the judgment result is the temperature of the underfloor heating water circuit in the current area... If the value exceeds the second set value, the opening of the regulating valve of the underfloor heating water circuit in the current area will be adjusted to the maximum. By setting the second set value again, the temperature of the underfloor heating water circuit can be controlled more precisely. At the same time, by adjusting the proportional relationship between the valve ratio and the temperature ratio, the corresponding algorithm for the automatic valve control opening can be obtained, so that the underfloor heating water circuit can control the temperature more accurately, save heating resources, and improve heating comfort.
[0021] In one technical solution of the present invention, the change in the opening degree of the regulating valve satisfies the following relationship:
[0022] ;
[0023] in, This refers to the opening coefficient of the regulating valve in the current area's underfloor heating water circuit. To adjust the angle when the valve is fully open, This is the second set value. The real-time temperature T and target temperature T of the current area's underfloor heating water system. 目标 The difference; k is the temperature compensation parameter; The opening degree of the current area's underfloor heating water circuit regulating valve and the angle when the regulating valve is fully open. The difference.
[0024] Compared with existing technologies, the technical effects achieved by this solution are as follows: due to the small temperature difference and the accuracy of 0.1℃, the compensation parameter k is increased to improve the control accuracy and make the temperature control more precise; furthermore, by using the proportional relationship between the valve opening ratio and the temperature ratio, the corresponding algorithm for the automatic control opening of the regulating valve can be derived, which facilitates the rapid adjustment of the regulating valve to the optimal opening, reduces system fluctuations caused by water temperature fluctuations or start-stop control, and extends the service life of the regulating valve and its control components.
[0025] In one technical solution of the present invention, based on the temperature difference ΔT R1-目标 ......△T Rn-目标 After controlling the regulating valves of the underfloor heating water circuits in at least two areas, the method further includes: if the operating time of the regulating valves of the underfloor heating water circuits in at least two areas reaches the set time; and then collecting the real-time temperature t of the underfloor heating water circuits in at least two areas again. R1 ......t Rn According to the real-time temperature t R1 ......t Rn Redetermine the target temperature t 目标 According to the target temperature t 目标 With real-time temperature t R1 ......t Rn Determine the temperature difference Δt between at least two regions.

R1-目标 ......△t Rn-目标 It does not exceed the first set value.
[0026] Compared with existing technologies, the technical effect achieved by adopting this technical solution is: by continuously monitoring the indoor underfloor heating temperature in real time within a set time period, the indoor underfloor heating water circuit is kept at a constant temperature, thereby improving heating comfort.
[0027] To achieve the second objective of this invention, the present invention provides a heat pump underfloor heating temperature control device, the temperature control device comprising: a temperature module for collecting real-time temperature T of the underfloor heating water pipes in at least two areas of the underfloor heating room.

[0042] As the concepts of comfortable living and integrated heating and cooling gradually gain popularity, "underfloor heating and air conditioning" are becoming increasingly popular among ordinary consumers. Currently, in addition to air conditioning and hot water production functions, indoor heat pump systems are also increasingly demanding heating from terminal types such as underfloor heating and radiators.
[0043] However, because indoor heat pump systems have long water circuits, and there is a need to extend the water circuits when multiple units are working together, the temperature control of underfloor heating is not precise, and the temperature difference in different locations of the underfloor heating system fluctuates greatly. Therefore, this application provides the following embodiments to solve the above problems.
[0044] [First Embodiment]
[0045] This embodiment provides a heat pump floor heating temperature control method, such as... Figure 1 As shown, the temperature control method includes: collecting the real-time temperature T of the underfloor heating water pipes in at least two areas of the room with underfloor heating. R1 ......T Rn According to the real-time temperature T R1 ...T Rn Determine the target temperature T in the room with underfloor heating. 目标 According to the target temperature T 目标 With real-time temperature T R1 ......T Rn Determine the temperature difference ΔT between at least two regions. R1-目标 ......△T Rn-目标 Based on the temperature difference ΔT R1-目标 ......△T Rn-目标 The regulating valves control the underfloor heating water circuits in at least two areas respectively.
[0046] Preferably, this invention determines the target temperature and temperature difference within the underfloor heating room by real-time acquisition of the temperature of the underfloor heating water pipes in each area, and then controls the regulating valves of the underfloor heating water circuits in each area based on the temperature difference. This temperature control method effectively ensures consistent temperature across all areas of the underfloor heating room, avoiding large temperature fluctuations in different locations, guaranteeing the stability of water and room temperature control, preventing repeated on / off cycles due to large water temperature fluctuations, improving user comfort, and allowing for more accurate water temperature values. Furthermore, this temperature control method improves system control efficiency, enhances system reliability, and increases the precision of floor temperature control, thereby achieving the goal of constant temperature in the underfloor heating system.
[0047] Furthermore, in this embodiment, the temperature of the underfloor heating water pipes in each area of the underfloor heating room is collected in real time by a temperature sensor, and the temperature sensor is installed in the underfloor heating water circuit, so the control of the water temperature is more precise.
[0048] In one embodiment of the present invention, based on the real-time temperature T R1 ...T Rn Determine the target temperature T in the room with underfloor heating. 目标 In the steps,
[0049] Target temperature T 目标 ;
[0050] Where n represents the number of zones in a room with underfloor heating.
[0051] Preferably, by real-time temperature T R1 ...T Rn Determine the target temperature T in the room with underfloor heating. 目标 In the process, since the water pipes in a room with underfloor heating are relatively short, the difference between different areas is small. Therefore, averaging is a more reliable and stable method because it is related to every data point and reflects the most complete information. It is the overall average temperature of the entire room with underfloor heating, which is more scientific.
[0052] Furthermore, the target temperature can be controlled according to the user's selected temperature control area without increasing the overall heating demand of the heat pump system, thus saving more energy; and after the user sets the initial target temperature, the heat pump system can automatically and adaptively control the temperature, making it more convenient to use.
[0053] In one embodiment of the present invention, based on the temperature difference ΔT R1-目标 ......△T Rn-目标 The regulating valves that control the underfloor heating water circuits in at least two areas respectively include: determining the temperature difference ΔT for each area. R1-目标 ......△TRn-目标 If the value exceeds the first set value, the regulating valve of the underfloor heating water circuit in the current area will be controlled based on the judgment result.
[0054] Preferably, it automatically judges the underfloor heating temperature by the difference, improving the heating efficiency of the underfloor heating system and saving energy and protecting the environment; and it can intelligently adjust the temperature according to different temperature zones, avoiding the problem of large temperature fluctuations in different locations of the underfloor heating system in the past.
[0055] In one embodiment of the present invention, controlling the regulating valve of the underfloor heating water circuit in the current area according to the judgment result includes: if the judgment result is no more than a first set value, then the regulating valve of the underfloor heating water circuit in the current area maintains the current opening degree; if the judgment result is more than the first set value, then controlling the opening degree of the regulating valve of the underfloor heating water circuit in the current area changes.
[0056] Preferably, by setting a first set value, the regulating valve of the underfloor heating water circuit can intelligently adjust the temperature according to different temperature zones to make the temperature control more precise; and the current zone refers to one of the zones in the underfloor heating water circuit. This application selects one temperature-controlled section for temperature control operation without increasing the overall heating demand of the heat pump system, which is more energy-efficient.
[0057] In one embodiment of the present invention, controlling the change in the opening degree of the regulating valve of the underfloor heating water circuit in the current area further includes: determining the temperature of the underfloor heating water circuit in the current area. If the value exceeds the second set value and the second set value is greater than the first set value, then adjust the opening of the regulating valve of the underfloor heating water circuit in the current area; if the value exceeds the second set value, then adjust the opening of the regulating valve of the underfloor heating water circuit in the current area to the maximum.
[0058] Preferably, when determining the temperature of the underfloor heating water circuit in the current area If the temperature does not exceed the second set value, adjust the opening of the regulating valve in the current area's underfloor heating water circuit; if the judgment result is the temperature of the underfloor heating water circuit in the current area... If the value exceeds the second set value, the opening of the regulating valve of the underfloor heating water circuit in the current area will be adjusted to the maximum. By setting the second set value again, the temperature of the underfloor heating water circuit can be controlled more precisely. At the same time, by adjusting the proportional relationship between the valve ratio and the temperature ratio, the corresponding algorithm for the automatic valve control opening can be obtained, so that the underfloor heating water circuit can control the temperature more accurately, save heating resources, and improve heating comfort.
[0059] Furthermore, since the temperature difference is small and the accuracy is generally 0.1℃, the first setting value can be set to an absolute value of the temperature difference not exceeding 0℃-0.1℃, preferably 0℃; the second setting value can be set to 1℃-5℃. Moreover, since the underfloor heating water circuit is relatively short, a 2℃ temperature difference results in a large difference in perceived temperature. Therefore, when the second setting value is preferably 2℃, the opening of the regulating valve of the underfloor heating water circuit in the current area is adjusted to the maximum to make the temperature adjustment more accurate and faster.
[0060] In one embodiment of the present invention, the change in the opening degree of the regulating valve satisfies the following relationship:
[0061] ;
[0062] in, This refers to the opening coefficient of the regulating valve in the current area's underfloor heating water circuit. To adjust the angle when the valve is fully open, This is the second set value. The real-time temperature T and target temperature T of the current area's underfloor heating water system. 目标 The difference; k is the temperature compensation parameter; The opening degree of the current area's underfloor heating water circuit regulating valve and the angle when the regulating valve is fully open. The difference.
[0063] Preferably, since the temperature difference is small and the accuracy is generally 0.1℃, the compensation parameter k is increased to improve the control accuracy and make the temperature control more precise. Furthermore, by using the proportional relationship between the valve opening ratio and the temperature ratio, the corresponding algorithm for the automatic control opening of the regulating valve can be obtained, which facilitates the rapid adjustment of the regulating valve to the optimal opening. This can reduce system fluctuations caused by water temperature fluctuations or start-stop control and extend the service life of the regulating valve and its control components.
[0064] Furthermore, the difference between the current water valve angle and the angle when the water valve is fully open is Δθ, and the difference between the current sensor temperature and the average temperature is Δt. Currently, The angle at which the regulating valve is fully open is typically 90°. The second set value is generally 2℃. The opening coefficient of the regulating valve for the current underfloor heating water circuit in the area is 0.5-2. The preferred value is 1, therefore the change in the valve opening satisfies the following relationship:
[0065] ;
