Description

Technical Field

[0001] This application relates to the technical field of heating equipment, and particularly to a heating control method, system, heating equipment and storage medium. Background Art

[0002] In non-central heating areas in the north, in the past, coal was burned to heat water and then the hot water was sent to the radiators in the room to achieve indoor heating. In recent years, the state has vigorously promoted the replacement of this clean heating method with air source heat pump units, and more and more households and enterprises have begun to purchase and use air source heat pump units.

[0003] Because floor heating has better comfort than radiators and does not occupy indoor area, users will mostly choose to install floor heating when building new houses, renovating or adding floors. Therefore, in actual use, there are many users and collectives who use radiators and floor heating together. The end of the floor heating has a large laying area and a large heat dissipation area, so the heat dissipation is large and the required water temperature is relatively low. The indoor temperature can reach a good level at a water temperature of 35-40 degrees. However, the radiator has a small heat dissipation area and requires a higher water temperature to emit a large amount of heat. Its water temperature generally needs to be above 50 degrees. But the air source heat pump unit can only set one outlet water temperature, and when the water temperature requirement of the floor heating end is met, the water temperature requirement of the radiator end cannot be met. That is, the existing air source heat pump unit cannot meet the water temperature requirements of both the floor heating end and the radiator end at the same time. Summary of the Invention

Among them, the heating mode is the radiator mode, the floor heating mode, or a hybrid mode in which both the radiator and the floor heating are enabled at the same time. When the heating mode is the hybrid mode, the working state of the air source heat pump unit in the heating control system and the on / off states of each water pump and switching valve in the hydraulic module of the heating control system are controlled according to the temperature detection data, so that the hot water temperature provided by the water tank in the hydraulic module for the radiator end meets the preset radiator temperature, and at the same time, the hot water temperature provided by the water tank for the floor heating end meets the preset floor heating temperature.

[0007] In a second aspect, the present application provides a heating control method, which is applied to the heating control system as described above. The method includes:

[0008] Obtain the heating mode and temperature detection data of the heating control system. Among them, the heating mode is the radiator mode, the floor heating mode, or a hybrid mode in which both the radiator and the floor heating are enabled at the same time.

[0009] When the heating mode is the hybrid mode, the working state of the air source heat pump unit in the heating control system and the on / off states of each water pump and switching valve in the hydraulic module of the heating control system are controlled according to the temperature detection data, so that the hot water temperature provided by the water tank in the hydraulic module for the radiator end meets the preset radiator temperature, and at the same time, the hot water temperature provided by the water tank for the floor heating end meets the preset floor heating temperature.

The air source heat pump unit is used to provide hot water for the water tank in the hydraulic module according to a set temperature.

To simplify the disclosure of the present invention, the components and configurations of specific examples are described below. Of course, these are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numerals and / or letters in different examples.

[0023] Figure 1 FIG. 1 is an application environment diagram of a heating control method in an embodiment. Figure 1 The heating control method is applied to a heating control system. The heating control system includes an air source heat pump unit 110, a heating control device, and a hydraulic module 130. The air source heat pump unit 110 is used to provide hot water to the water tank according to a set temperature. The hydraulic module 130 includes a water tank. The connecting pipes between the water tank and the air source heat pump unit 110, between the water tank and the radiator terminal 141, and between the water tank and the floor heating terminal 142 are respectively provided with a water pump, a switch valve, and a temperature sensor.

[0024] The heating control device 120 is used to obtain the heating mode and temperature detection data of the heating control system, wherein the heating mode is a radiator mode, a floor heating mode or a mixed mode in which radiators and floor heating are enabled at the same time; when the heating mode is a mixed mode, the working state of the air source heat pump unit 110 in the heating control system and the switching states of each water pump and switch valve in the hydraulic module 130 in the heating control system are controlled according to the temperature detection data, so that the hot water temperature provided by the water tank in the hydraulic module 130 to the radiator terminal 141 meets the preset radiator temperature, and at the same time, the hot water temperature provided by the water tank to the floor heating terminal 142 meets the preset floor heating temperature.

[0025] Specifically, the air source heat pump unit 110 is used to supply hot water to the water tank according to a set temperature, and the set temperature is the higher preset temperature among the preset radiator temperature and the preset floor heating temperature. The preset radiator temperature is denoted as Tn, and the preset floor heating temperature is denoted as Td. The preset radiator temperature and the preset floor heating temperature are the heating temperatures set by the user for the radiator terminal 141 and the floor heating terminal 142 respectively. When the preset radiator temperature is greater than the preset floor heating temperature, the set temperature is the preset radiator temperature; when the preset radiator temperature is less than the preset floor heating temperature, the set temperature is the preset floor heating temperature. Usually, the preset radiator temperature is greater than the preset floor heating temperature, that is, Tn > Td. Therefore, the air source heat pump unit 110 is controlled to supply hot water to the water tank according to the preset radiator temperature.

[0026] The water tank is used to store the hot water provided by the air source heat pump unit 110, and the heating control device 120 is used to obtain the temperature data collected by each temperature sensor and obtain the heating mode in which the heating control system is located. When the heating mode is the mixed mode, it means that the user needs to use the radiator terminal 141 and the floor heating terminal 142 at the same time. Then, according to the temperature detection data, the working state of the air source heat pump unit 110 and the opening and closing states of each water pump and switch valve in the system are controlled. The working state is divided into the running state and the shutdown state, and the opening and closing state is divided into the open state and the closed state. When in the open state, the opening degrees of the water pump and the switch valve are automatically and dynamically adjusted based on the terminal heating situation. Based on the air source heat pump unit 110 being in different working states and different switch valves and water pumps being in different opening and closing states, the water tank can supply hot water at different temperatures to the radiator terminal 141 and the floor heating terminal 142 respectively, so as to simultaneously meet the temperature requirements of the floor heating terminal 142 and the radiator terminal 141.

[0027] In one embodiment, referring to Figure 2 , the connecting pipeline between the air source heat pump unit 110 and the water tank includes a unit outlet pipeline and a unit inlet pipeline. The connecting pipeline between the water tank and the radiator terminal 141 includes a radiator inlet pipeline and a radiator outlet pipeline. The connecting pipeline between the water tank and the floor heating terminal 142 includes a floor heating inlet pipeline and a floor heating outlet pipeline. Temperature sensors are respectively provided on the unit outlet pipeline, the unit inlet pipeline, the radiator inlet pipeline, the radiator outlet pipeline, the floor heating inlet pipeline, and the floor heating outlet pipeline, and a temperature sensor is provided inside the water tank;

[0028] A first three-way diversion valve (three-way valve 2) is provided on the unit outlet pipeline, and a third water pump (water pump 13) is provided on the unit inlet pipeline;

[0029] The radiator inlet pipeline includes a first branch, a second branch, and a third branch. The first branch is connected to the first three-way shunt valve, and a first water pump (water pump 4) is provided on the first branch. A two-way valve is provided on the second branch. The first end of the second branch is connected to the water tank, and the second end of the second branch is connected between the first three-way shunt valve and the first water pump. The first end of the third branch is connected between the second end of the second branch and the first water pump, and the second end of the third branch is connected to a three-way confluence valve (three-way valve 8) on the floor heating inlet pipeline;

[0030] A second water pump (water pump 7) is further provided on the floor heating inlet pipeline. The three-way confluence valve is located between the water tank and the second water pump. A second three-way shunt valve (three-way valve 12) is provided on the floor heating outlet pipeline. The third end of the three-way shunt valve is connected to the second water pump through a connecting pipeline between the three-way confluence valve and the second water pump;

[0031] Among them, when the first three-way shunt valve is in a fully closed state, the water output of the air source heat pump unit 110 only flows to the first water pump. When the first three-way shunt valve is in a fully open state, the water output of the air source heat pump unit 110 only flows to the water tank; when the second three-way shunt valve is in a fully closed state, the floor heating water output of the floor heating terminal 142 only flows to the water tank. When the second three-way shunt valve is in a fully open state, the floor heating water output of the floor heating terminal 142 only flows to the second water pump; when the three-way confluence valve is in a fully closed state, the hot water provided by the water tank only flows to the second water pump. When the three-way confluence valve is in a fully open state, the hot water provided by the water tank cannot flow to the second water pump, and the hot water provided for the first water pump is diverted to the second water pump through the fully open three-way confluence valve.

[0032] Specifically, referring to Figure 2 , 1, 5, 6, 9, 10, 11, 14, 15 are temperature sensors (the temperatures detected by them are T1, T5, T6, T9, T10, T11, T14, Ts) respectively, 2, 12 are electric regulating three-way shunt valves, 8 is an electric regulating three-way confluence valve, 3 is an electric two-way valve (which plays a on-off role. When it is powered on, it opens and there is flow. When it is powered off, it closes and there is no flow), 4, 7 are variable frequency water pumps, and 13 is a fixed frequency water pump.

[0033] The multiple water pumps specifically include a first water pump, a second water pump, and a third water pump. The first water pump and the second water pump are implemented by variable frequency water pumps, and the third water pump is implemented by a fixed frequency water pump. The multiple on-off valves specifically include a two-way valve, a first three-way shunt valve, a second three-way shunt valve, and a three-way confluence valve. Referring to Figure 2, the first water pump is water pump 4, the third water pump is water pump 13, the second water pump is water pump 7, the first three-way diverter valve is three-way valve 2, the second three-way diverter valve is three-way valve 12, and the three-way confluence valve is three-way valve 8.

[0034] Refer to Figure 2 , the first three-way diverter valve and the second three-way diverter valve are electrically adjustable three-way diverter valves, with one inlet and two outlets. The larger the opening degree, the more the flow rate in the XZ vertical branch and the less the flow rate in the XY horizontal branch. When the opening degree is in the fully open state, all the water flow passes through the vertical branch and there is no flow in the horizontal branch; when the opening degree is in the fully closed state, there is no flow in the vertical branch and all the water flow passes through the horizontal branch.

[0035] The three-way confluence valve has two inlets and one outlet. The larger the opening degree, the more the flow rate in the VW vertical branch and the less the flow rate in the UW horizontal branch. When the opening degree is in the fully open state, all the water flow passes through the vertical branch and there is no flow in the horizontal branch; when the opening degree is in the fully closed state, there is no flow in the vertical branch and all the water passes through the horizontal branch.

[0036] The first three-way diverter valve is used to control the water flow rate provided by the air source heat pump unit 110 for the water tank and the radiator terminal 141. That is, when the first three-way diverter valve is in the fully open state, no hot water is provided to the heating terminal, and all the water flow goes through the vertical branch and is provided to the water tank. When the first three-way diverter valve is in the fully closed state, no water flow is provided to the water tank, and all the water flow goes through the horizontal branch and is provided to the radiator terminal 141 through the first water pump. That is, the opening degree of the first water pump is used to control the water flow rate entering the radiator terminal 141. If the three-way confluence valve is in the fully open state at this time, part of the water flow rate provided by the air source heat pump unit 110 for the radiator terminal 141 through the first three-way diverter valve is provided to the radiator terminal 141 through the first water pump, and part of the water flow rate passes through the three-way confluence valve to provide the second water pump. When the second water pump is in the open state, the water flow rate passing through the three-way confluence valve will be provided to the floor heating terminal 142.

[0037] If the three-way confluence valve is in the fully closed state, all the water flow rate provided by the air source heat pump unit 110 for the radiator terminal 141 through the first three-way diverter valve is provided to the radiator terminal 141 through the first water pump. However, at this time, the water flow rate provided by the water tank will all be provided to the second water pump through the fully closed three-way confluence valve, and hot water is provided to the floor heating terminal 142 by turning on the second water pump. That is, the opening degree of the second water pump is used to control the water flow rate entering the floor heating terminal 142.

[0038] The opening degree of the second three-way diverter valve is used to control the water flow rate of the floor heating outlet water flowing from the floor heating end 142 to the second water pump and the water flow rate flowing to the water tank. Generally, the floor heating outlet water temperature is lower than the floor heating inlet water temperature. Therefore, by adjusting the opening degree of the second three-way diverter valve, the floor heating outlet water and the floor heating inlet water with different flow rates can be mixed to reduce the hot water temperature provided to the floor heating end 142, so that the hot water at the floor heating end 142 meets the floor heating requirements.

[0039] The third water pump is used to control the on-off of the unit inlet water pipeline between the water tank and the air source heat pump unit 110. When the third water pump is turned on, the water tank can provide water flow to the air source heat pump unit 110. When the third water pump is turned off, the water tank cannot provide water flow to the air source heat pump unit 110.

[0040] The two-way valve is used to control whether the water tank can provide water flow to the radiator end 141. When the two-way valve is opened, the water tank can provide water flow to the radiator end 141 through the opened first water pump. When the two-way valve is closed, the water tank cannot provide water flow to the first water pump.

[0041] Under different heating modes, adjust the on-off states of the first three-way diverter valve, the second three-way diverter valve, the three-way confluence valve, the first water pump, the second water pump, the third water pump, and the two-way valve according to the corresponding heating requirements, so as to adjust the floor heating inlet water temperature of the floor heating end 142 and the radiator inlet water temperature of the radiator end 141, make the floor heating inlet water temperature equal to the preset floor heating temperature, and make the radiator inlet water temperature equal to the preset radiator temperature.

[0042] In one embodiment, Figure 3 is a schematic flow chart of a heating control method in one embodiment. Referring to Figure 3 , a heating control method is provided. In this embodiment, the method is mainly illustrated by applying it to the heating control device 120 in the above Figure 1 . The heating control method specifically includes the following steps:

[0043] Step S210, obtain the heating mode and temperature detection data of the heating control system, where the heating mode is the radiator mode, the floor heating mode, or a mixed mode of simultaneously enabling the radiator and the floor heating.

[0044] Specifically, the radiator mode means that the user only turns on the radiator, the floor heating mode means that the user only turns on the floor heating, and the mixed mode means that the radiator and the floor heating are turned on simultaneously. The temperature detection data includes the detected temperatures of each temperature sensor in the heating control system.

[0045] Step S220: When the heating mode is the hybrid mode, control the working state of the air source heat pump unit 110 in the heating control system and the on / off states of each water pump and switch valve in the hydraulic module 130 in the heating control system, so that the hot water temperature provided by the water tank in the hydraulic module 130 for the radiator end 141 meets the preset radiator temperature, and at the same time, the hot water temperature provided by the water tank for the floor heating end 142 meets the preset floor heating temperature.

[0046] Specifically, in the hybrid mode, control the working state of the air source heat pump unit 110 according to the corresponding heating demand, and adjust the on / off states of each water pump and switch valve in the hydraulic module 130, so as to adjust the floor heating inlet water temperature of the floor heating end 142 and the radiator inlet water temperature of the radiator end 141, make the floor heating inlet water temperature equal to the preset floor heating temperature, and make the radiator inlet water temperature equal to the preset radiator temperature, so as to solve the problem that the existing air source heat pump unit 110 cannot provide different outlet water temperatures for different ends at the same time.

[0047] In one embodiment, the temperature detection data includes the water tank temperature, the radiator inlet water temperature, the radiator outlet water temperature, the floor heating inlet water temperature, and the floor heating outlet water temperature. The controlling the working state of the air source heat pump unit 110 in the heating control system and the on / off states of each water pump and switch valve in the hydraulic module 130 in the heating control system according to the temperature detection data includes at least one of the following:

[0048] When the water tank temperature is less than or equal to the temperature threshold, control the air source heat pump unit 110 to be in the operating state, open the first three-way diverter valve on the radiator inlet water path between the hydraulic module 130 and the radiator end 141, and the third water pump on the unit inlet water path between the hydraulic module 130 and the air source heat pump unit 110, and close the first water pump, the two-way valve on the radiator inlet water path between the hydraulic module 130 and the radiator end 141, the three-way confluence valve on the floor heating inlet water path between the hydraulic module 130 and the floor heating end 142, the second water pump, and the second three-way diverter valve on the floor heating outlet water path between the hydraulic module 130 and the floor heating end 142;

[0049] When the air source heat pump unit 110 is in a shutdown state and the temperature difference between the preset radiator temperature and the water tank temperature is greater than or equal to the first preset temperature difference, or when the air source heat pump unit 110 is in an operating state and the inlet water temperature of the radiator is less than the preset radiator temperature, control the air source heat pump unit 110 to be in an operating state, open the first water pump according to the first preset opening degree, open the second water pump according to the second preset opening degree, open the third water pump, close the first three-way diverter valve, the two-way valve, the second three-way diverter valve, and the three-way confluence valve. When the control duration reaches the preset duration, then adjust the opening degrees of the first three-way diverter valve, the second three-way diverter valve, and the three-way confluence valve according to the first preset adjustment scheme, so as to adjust the inlet water temperature of the radiator in the radiator inlet water pipeline to the preset radiator temperature, and adjust the inlet water temperature of the floor heating in the floor heating inlet water pipeline to the preset floor heating temperature;

[0050] When the air source heat pump unit 110 is in a shutdown state, the temperature difference between the preset radiator temperature and the water tank temperature is less than the first preset temperature difference, and the water tank temperature is less than the preset radiator temperature, control the air source heat pump unit 110 to be in a shutdown state, open the first water pump according to the first preset opening degree, open the second water pump according to the second preset opening degree, close the third water pump, the first three-way diverter valve, the three-way confluence valve, and the second three-way diverter valve, open the two-way valve. When the control duration reaches the preset duration, then adjust the opening degrees of the first water pump, the second water pump, and the second three-way diverter valve according to the second preset adjustment scheme, so as to adjust the inlet water temperature of the radiator in the radiator inlet water pipeline to the preset radiator temperature, and reduce the inlet water temperature of the floor heating in the floor heating inlet water pipeline to the preset floor heating temperature.

[0051] Specifically, the water tank temperature is denoted as Ts, the temperature threshold is denoted as Tc, referring to Figure 2 The inlet water temperature of the radiator is the temperature collected by the temperature sensor 5 in the hydraulic module 130, denoted as T5; the outlet water temperature of the radiator is the temperature collected by the temperature difference sensor 10 in the hydraulic module 130, denoted as T10; the inlet water temperature of the floor heating is the temperature collected by the temperature sensor 6 in the hydraulic module 130, denoted as T6; the outlet water temperature of the floor heating is the temperature collected by the temperature sensor 11 in the hydraulic module 130, denoted as T11.

[0052] Referring to Figure 2, the temperature collected by temperature sensor 1 is the water outlet temperature of the unit, denoted as T1; the temperature collected by temperature sensor 9 is the water outlet temperature of the water tank, denoted as T9; the temperature collected by temperature sensor 14 is the water outlet temperature of the water tank, denoted as T10. The first water pump is water pump 4, the third water pump is water pump 13, the second water pump is water pump 7, the first three-way flow divider valve is three-way valve 2, the second three-way flow divider valve is three-way valve 12, and the three-way flow combiner valve is three-way valve 8.

[0053] When the user turns on the floor heating and radiator at the same time:

[0054] (1) If Ts ≤ Tc, then control the air source heat pump unit 110 and each water pump and switch valve according to Table 1 below:

[0055]

[0056] Table 1

[0057] That is, when the water tank temperature is lower than the temperature threshold, the end water circuit does not start circulating. First, use the air source heat pump unit 110 to circulate hot water to the water tank to raise the water temperature in the water tank, and then start the end water circulation. In weather with high humidity, the air source heat pump unit 110 frosts quickly. The control method in Table 1 can also be used to quickly increase the water temperature flowing through the air source heat pump unit 110, so that the air source heat pump unit 110 defrosts faster.

[0058] (2) If the air source heat pump unit 110 is in the off state and it is detected that Ts ≤ Tn - △t, that is, △t ≤ Tn - Ts, where △t is the first preset temperature difference, and the first preset temperature difference is the unit start-up water temperature difference, and its value range is 3 - 8 °C, or the air source heat pump unit 110 is in the running state and it is detected that T5 < Tn, then control the air source heat pump unit 110 and each water pump and switch valve according to Table 2 below:

[0059]

[0060] Table 2

[0061] That is, when the heating control system is started but the air source heat pump unit 110 is in a shutdown state, indicating that the air source heat pump unit 110 has not been started yet. At this time, if the detected temperature difference between the preset radiator temperature and the water tank temperature is large, it means that the water temperature in the water tank cannot meet the temperature requirement of the radiator end 141. Or when the air source heat pump unit 110 is in operation and the detected inlet water temperature of the radiator is lower than the preset radiator temperature, the air source heat pump unit 110 needs to directly supply hot water to the radiator end 141 to meet the temperature requirement of the radiator end 141. Open the first water pump according to the first preset opening degree, and open the second water pump according to the second preset opening degree. Since the larger the opening degree of the water pump, the higher the energy consumption, but the smaller the opening degree of the water pump, the worse the heat dissipation effect at the end. Therefore, it is necessary to balance the opening degree of the water pump to avoid excessive energy consumption or poor heat dissipation effect at the end. The first preset opening degree and the second preset opening degree can be custom-set according to actual application requirements or set according to operation experience. The first preset opening degree and the second preset opening degree can be the same or different. In this embodiment, the first preset opening degree is set equal to the second preset opening degree, both being 50%.

[0062] When the three-way valve 2 is fully closed, all the water output from the unit flows to the first water pump. The closing of the two-way valve 3 means that the water tank will not supply water to the first water pump. The full closing of the three-way valve 8 means that all the water output from the water tank flows to the second water pump. The full closing of the three-way valve 12 means that all the water output from the floor heating flows into the water tank. That is, the water output from the unit is directly provided to the radiator end 141 through the opened first water pump, directly providing hot water with a higher temperature to the radiator end 141. The temperature of the water tank is lower than the preset radiator temperature, but the water tank temperature may be greater than or equal to the preset floor heating temperature. Therefore, the water tank can be used to provide hot water with a lower temperature to the floor heating end 142, so as to realize providing hot water with different temperatures to different ends.

[0063] When the control duration of controlling according to Table 2 above reaches the preset duration, then adjust the opening degrees of the first three-way diverter valve, the second three-way diverter valve, and the three-way confluence valve according to the first preset adjustment scheme, that is, dynamically adjust the opening degrees of the three three-way valves according to the heat dissipation conditions of the radiator end 141 and the floor heating end 142 at the end of the control duration, so that the inlet water temperature of the radiator reaches the preset radiator temperature, that is, make T5 = Tn, and make the inlet water temperature of the floor heating reach the preset floor heating temperature, that is, make T6 = Td, to simultaneously meet the temperature requirements of the floor heating end 142 and the radiator end 141.

[0064] (3) If the air source heat pump unit 110 is in the off state and it is detected that Tn - △t < Ts < Tn, that is, Tn - Ts < △t, then control the air source heat pump unit 110 and each water pump and switch valve according to Table 3 below:

[0065]

[0066] Table 3

[0067] That is, when the heating control system is started, but the air source heat pump unit 110 is in a shutdown state, indicating that the air source heat pump unit 110 has not been started yet. At this time, it is detected that the temperature difference between the preset radiator temperature and the water tank temperature is small, but the water tank temperature is lower than the preset radiator temperature. And the preset floor heating temperature is usually more than 10 °C lower than the preset radiator temperature. Therefore, the water temperature in the water tank at this time meets the temperature requirement of the floor heating terminal 142, that is, Ts>Td. Then there is no need to start the air source heat pump unit 110 to continue heating the water tank. Therefore, the air source heat pump unit 110 is turned off to make it in a shutdown state, and the water outlet of the unit is blocked from entering the water tank through the fully closed three-way valve 2, and all the water outlet of the unit flows through the opened first water pump to the radiator terminal 141. The water pump 13 is closed to prevent the water outlet of the water tank from entering the air source heat pump unit 110. At this time, by opening the two-way valve 3, the water tank is used to provide hot water for the radiator terminal 141 at the same time. The fully closed three-way valve 8 and the fully closed three-way valve 12 indicate that the water tank is used to provide hot water for the floor heating terminal 142.

[0068] Continuously using the water tank to provide hot water with a higher temperature for the floor heating terminal 142 will cause the heat dissipation temperature of the floor heating terminal 142 to be higher than the preset floor heating temperature. Therefore, when the control duration of controlling according to Table 3 reaches the preset duration, it is necessary to adjust the opening degrees of the first water pump (water pump 4), the second water pump (water pump 7), and the second three-way shunt valve (three-way valve 12) according to the second preset adjustment scheme to reduce the floor heating inlet water temperature, that is, to achieve T6 = Td. And the air source heat pump unit 110 continuously provides high-temperature hot water for the radiator terminal 141 through the fully closed three-way valve 2, and ultimately T5 = Tn can be achieved, so that hot water with different temperatures can be provided for different terminals.

[0069] In one embodiment, adjusting the opening degrees of the first three-way shunt valve, the second three-way shunt valve, and the three-way confluence valve according to the first preset adjustment scheme includes:

[0070] Obtain the radiator inlet water temperature and the floor heating inlet water temperature;

[0071] Determine the adjustment opening degree according to the product of the temperature difference between the floor heating inlet water temperature and the preset floor heating temperature and the adjustment coefficient;

[0072] According to the comparison result between the radiator inlet water temperature and the preset radiator temperature, and the comparison result between the floor heating inlet water temperature and the preset floor heating temperature, perform one of the following:

[0073] When the inlet water temperature of the radiator is equal to the preset radiator temperature and the inlet water temperature of the floor heating is less than the preset floor heating temperature, reduce the opening degree of the second three-way diverter valve according to the adjustment opening degree, and repeatedly execute the steps of obtaining the inlet water temperature of the radiator and the inlet water temperature of the floor heating until the opening degree of the second three-way diverter valve is reduced to the fully closed state. Then, increase the opening degree of the three-way confluence valve according to the adjustment opening degree, and repeatedly execute the steps of obtaining the inlet water temperature of the radiator and the inlet water temperature of the floor heating until the opening degree of the three-way confluence valve reaches the first specified opening degree. Next, increase the opening degree of the first three-way diverter valve according to the adjustment opening degree, and repeatedly execute the steps of obtaining the inlet water temperature of the radiator and the inlet water temperature of the floor heating until the opening degree of the first three-way diverter valve reaches the second specified opening degree;

[0074] When the inlet water temperature of the radiator is less than the preset radiator temperature and the inlet water temperature of the floor heating is less than the preset floor heating temperature, execute the step of controlling the air source heat pump unit 110 to be in the operating state, opening the first water pump according to the first preset opening degree, opening the second water pump according to the second preset opening degree, turning on the third water pump, closing the first three-way diverter valve, the two-way valve, the second three-way diverter valve, and the three-way confluence valve, and when the control duration reaches the preset duration, adjusting the opening degrees of the first three-way diverter valve, the second three-way diverter valve, and the three-way confluence valve according to the first preset adjustment scheme;

[0075] When the inlet water temperature of the radiator is less than the preset radiator temperature and the inlet water temperature of the floor heating is equal to the preset floor heating temperature, keep the opening degrees of the first three-way diverter valve, the second three-way diverter valve, and the three-way confluence valve unchanged;

[0076] When the inlet water temperature of the radiator is less than the preset radiator temperature and the inlet water temperature of the floor heating is greater than the preset floor heating temperature, reduce the opening degree of the first three-way diverter valve according to the adjustment opening degree, and repeatedly execute the steps of obtaining the inlet water temperature of the radiator and the inlet water temperature of the floor heating until the opening degree of the first three-way diverter valve reaches the fully closed state. Then, reduce the opening degree of the three-way confluence valve according to the adjustment opening degree, and repeatedly execute the steps of obtaining the inlet water temperature of the radiator and the inlet water temperature of the floor heating until the opening degree of the three-way confluence valve reaches the fully closed state. Next, increase the opening degree of the second three-way diverter valve according to the adjustment opening degree, and repeatedly execute the steps of obtaining the inlet water temperature of the radiator and the inlet water temperature of the floor heating.

[0077] Specifically, the adjusted opening degree D = k * a, where a = T6 - Td, k is the adjustment coefficient, and the value of k ranges from 1 to 6. a can be positive or negative according to the change of the floor heating inlet water temperature. When the control duration of the control according to Table 2 reaches the preset duration, the radiator inlet water temperature is compared with the preset radiator temperature, and the floor heating inlet water temperature is compared with the preset floor heating temperature. Then, according to the comparison results, the first three-way diverter valve (three-way valve 2), the second three-way diverter valve (three-way valve 12), and the three-way confluence valve (three-way valve 8) are dynamically adjusted so that T5 = Tn and T6 = Td, thereby realizing the supply of hot water with different temperatures to different terminals.

[0078] 1) If T5 = Tn and T6 < Td, it means that the radiator inlet water temperature reaches the preset radiator temperature, while the floor heating inlet water temperature is still lower than the preset floor heating temperature. To increase the floor heating inlet water temperature, the second three-way diverter valve is preferentially adjusted, that is, the opening degree of the three-way valve 12 is preferentially adjusted. According to the adjusted opening degree, the opening degree of the three-way valve 12 is reduced. For example, the opening degree of the three-way valve 12 = the current opening degree - D. When the opening degree of the three-way valve 12 is reduced, the vertical flow rate will be reduced and the horizontal flow rate will be increased, that is, the XY direction flow rate will be increased and the XZ direction flow rate will be reduced, so as to reduce the water flow rate transferred from the floor heating outlet to the floor heating inlet end. Since the floor heating outlet water temperature is lower than the floor heating inlet water temperature, this can reduce the temperature reduction effect of the floor heating outlet on the floor heating inlet, thereby increasing the floor heating inlet water temperature.

[0079] Until the opening degree of the three-way valve 12 is reduced to the fully closed state, at this time, no floor heating outlet water enters the floor heating inlet end. However, if the newly obtained radiator inlet water temperature and floor heating inlet water temperature still meet the above conditions (T5 = Tn, T6 < Td), the three-way confluence valve (three-way valve 8) is further adjusted. According to the newly obtained radiator inlet water temperature and floor heating inlet water temperature through recycling, a new adjusted opening degree is recalculated, and the opening degree of the three-way valve 8 is increased using the adjusted opening degree calculated by the new cycle. For example, the opening degree of the three-way valve 8 = the current opening degree + D, so as to increase the vertical flow rate and reduce the horizontal flow rate, that is, increase the VW direction flow rate and reduce the UW direction flow rate, and increase the water flow rate of the unit outlet diverted to the floor heating inlet end, and increase the floor heating inlet water temperature by increasing the water flow rate of the high-temperature unit outlet water to the floor heating inlet end.

[0080] Until the opening degree of the three-way valve 8 increases to the first specified opening degree, the value range of the first specified opening degree is 50% to 80%. In this embodiment, the first specified opening degree is set to 70%. When the opening degree of the three-way valve 8 increases to 70%, if the re-acquired radiator inlet water temperature and the floor heating inlet water temperature still meet the above (T5 = Tn, T6 < Td) conditions, then further adjust the first three-way diverter valve (three-way valve 2), recalculate the new adjustment opening degree according to the re-cycled acquired radiator inlet water temperature and the floor heating inlet water temperature, and increase the opening degree of the three-way valve 2 by using the adjustment opening degree calculated by the new cycle. For example, the opening degree of the three-way valve 2 = the current opening degree + D, so as to increase the vertical direction flow rate and decrease the horizontal direction flow rate, that is, increase the XZ direction flow rate and decrease the XY direction flow rate, increase the water flow rate of the unit outlet water diverted to the water tank, and decrease the water flow rate of the unit outlet water diverted to the radiator end 141. By adding high-temperature hot water to the water tank, the outlet water temperature of the water tank can be increased. The heated water tank outlet water is transmitted to the floor heating end 142 through the three-way valve 8 with an opening degree of 70% to increase the floor heating inlet water temperature.

[0081] 2) If T5 < Tn, T6 < Td, then control according to Table 2 above. First, the air source heat pump unit 110 directly provides hot water for the radiator end 141 to increase the radiator inlet water temperature. When the control duration reaches the preset duration, re-execute the above steps of obtaining the radiator inlet water temperature and the floor heating inlet water temperature to enter a new dynamic adjustment cycle.

[0082] 3) If T5 < Tn, T6 = Td, it means that the floor heating inlet water temperature reaches the preset floor heating temperature, while the radiator inlet water temperature is lower than the preset radiator temperature. Only need to keep the opening degree of each three-way valve unchanged and continue to operate for a period of time. As time goes by, continuously heated hot water enters the radiator end 141 to slowly increase the radiator inlet water temperature until the radiator inlet water temperature reaches the preset radiator temperature.

[0083] 4) If T5 < Tn, T6 > Td, it means that the floor heating inlet water temperature is higher than the preset floor heating temperature, but the radiator inlet water temperature is lower than the preset radiator temperature. Then, first adjust the first three-way diverter valve (three-way valve 2), and decrease the opening degree of the three-way valve 2 according to the adjustment opening degree. For example, the opening degree of the three-way valve 2 = the current opening degree - D. When the opening degree of the three-way valve 2 decreases, the vertical direction flow rate will decrease and the horizontal direction flow rate will increase, that is, increase the XY direction flow rate and decrease the XZ direction flow rate, so as to reduce the water flow rate of the unit outlet water transmitted to the water tank, and increase the water flow rate of the unit outlet water transmitted to the radiator end 141. This can inhibit the heating effect of the hot water in the water tank, thereby inhibiting the continuous increase of the floor heating inlet water temperature, and increasing the radiator inlet water temperature by increasing the water flow rate of the unit outlet water directly leading to the radiator end 141.

[0084] Until the opening of the three-way valve 2 is reduced to the fully closed state, at this time, no unit effluent enters the water tank, and all the unit effluent flows to the radiator end 141. However, if the recaptured radiator inlet water temperature and the floor heating inlet water temperature still meet the above conditions (T5 < Tn, T6 > Td), then further adjust the three-way confluence valve (three-way valve 8). Recalculate the new adjustment opening according to the recaptured radiator inlet water temperature and the floor heating inlet water temperature. Use the adjustment opening calculated by the new cycle to reduce the opening of the three-way valve 8. For example, the opening of the three-way valve 8 = the current opening - D, to reduce the vertical flow rate and increase the horizontal flow rate, that is, to reduce the flow rate in the VW direction and increase the flow rate in the UW direction, and reduce the water flow rate of the unit effluent diverted to the floor heating inlet end, thereby suppressing the continuous increase of the floor heating inlet water temperature, and providing most of the water flow rate of the unit effluent to the radiator end 141, and improving the radiator inlet water temperature by increasing the high-temperature unit effluent water flow rate at the radiator inlet end.

[0085] Until the opening of the three-way valve 8 is reduced to the fully closed state, at this time, no unit effluent flows to the floor heating end 142, and all the unit effluent flows to the radiator end 141. However, if the recaptured radiator inlet water temperature and the floor heating inlet water temperature still meet the above conditions (T5 < Tn, T6 > Td), then further adjust the second three-way diverter valve (three-way valve 12). Recalculate the new adjustment opening according to the recaptured radiator inlet water temperature and the floor heating inlet water temperature. Use the adjustment opening calculated by the new cycle to increase the opening of the three-way valve 12. For example, the opening of the three-way valve 12 = the current opening + D, to increase the vertical flow rate and reduce the horizontal flow rate, that is, to increase the flow rate in the XZ direction and reduce the flow rate in the XY direction, and increase the water flow rate of the floor heating effluent flowing to the floor heating inlet end. Since the floor heating effluent temperature is lower than the floor heating inlet water temperature, the floor heating inlet water temperature can be reduced by increasing the low-temperature floor heating effluent at the floor heating inlet end, so that T6 = Td. And the air source heat pump unit 110 continuously provides high-temperature hot water to the radiator end 141 through the fully closed three-way valve 2, and finally T5 = Tn can be achieved, so that hot water at different temperatures can be provided for different ends.

[0086] In one embodiment, adjusting the first water pump and the second water pump according to the second preset adjustment scheme includes:

[0087] Obtain the floor heating water temperature difference between the floor heating inlet water temperature and the floor heating outlet water temperature, and the radiator water temperature difference between the radiator inlet water temperature and the radiator outlet water temperature;

[0088] When the target water temperature difference is greater than the second preset water temperature difference, increase the opening of the water pump corresponding to the target water temperature difference according to the preset adjustment degree, where the target water temperature difference is the floor heating water temperature difference or the radiator water temperature difference, the radiator water temperature difference corresponds to the first water pump, and the floor heating water temperature difference corresponds to the second water pump;

[0089] When the target water temperature difference is less than the third preset temperature difference, reduce the opening degree of the variable frequency water pump corresponding to the target water temperature difference according to the preset adjustment degree, where the third preset temperature difference is less than the second preset temperature difference;

[0090] When the target water temperature difference is between the third preset temperature difference and the second preset temperature difference, keep the opening degree of the variable frequency water pump corresponding to the target water temperature difference unchanged.

[0091] Specifically, the water temperature difference of the floor heating is △td = T6 - T11, the water temperature difference of the radiator is △tn = T5 - T10, the second preset temperature difference and the third preset temperature difference are arbitrary values, and can be specifically set according to actual needs. In this embodiment, the second preset temperature difference is set to 6°C and the third preset temperature difference is set to 3°C. The preset adjustment degree is an arbitrary opening value. In this embodiment, the preset adjustment degree is set to 5%.

[0092] When △tn > 6°C, increase the opening degree of the first water pump by 5%; when △tn < 3°C, reduce the opening degree of the first water pump by 5%; when △tn = 3 - 6°C, keep the opening degree of the first water pump unchanged.

[0093] When △td > 6°C, increase the opening degree of the second water pump by 5%; when △td < 3°C, reduce the opening degree of the second water pump by 5%; when △td = 3 - 6°C, keep the opening degree of the second water pump unchanged.

[0094] When the adjustment duration of the first water pump or the second water pump reaches the preset interval, re - execute the steps of obtaining the water temperature difference of the floor heating between the floor heating inlet water temperature and the floor heating outlet water temperature, and the water temperature difference of the radiator between the radiator inlet water temperature and the radiator outlet water temperature. The value range of the preset interval is 1 - 5 minutes. In this embodiment, the preset interval is set to 2 minutes. Then, obtain the water temperature difference of the floor heating between the floor heating inlet water temperature and the floor heating outlet water temperature, and the water temperature difference of the radiator between the radiator inlet water temperature and the radiator outlet water temperature every 2 minutes, and adjust the opening degree of the first water pump or the second water pump once according to the comparison relationship between the water temperature difference and the second preset temperature difference, so as to dynamically balance the heat dissipation effect at the end and the energy consumption of the water pump.

[0095] In one embodiment, adjusting the second three - way flow - dividing valve according to the second preset adjustment scheme includes:

[0096] Obtain the radiator inlet water temperature and the floor heating inlet water temperature;

[0097] Determine the adjustment opening degree according to the product of the temperature difference between the floor heating inlet water temperature and the preset floor heating temperature and the adjustment coefficient;

[0098] Increase the opening degree of the second three - way flow - dividing valve according to the adjustment opening degree.

[0099] Specifically, on the basis of the control according to Table 3, with reference to the above embodiments, the opening degree D is adjusted as D = k*a, where a = T6 - Td, k is an adjustment coefficient, and the value of k ranges from 1 to 6. a can be positive or negative according to the change in the floor heating inlet water temperature. Increase the opening degree of the second three-way diversion valve (three-way valve 12) according to the adjusted opening degree. For example, the opening degree of the three-way valve 12 = the current opening degree + D, so as to increase the vertical direction flow rate and decrease the horizontal direction flow rate, that is, increase the XZ direction flow rate and decrease the XY direction flow rate, and increase the water flow rate of the floor heating outlet water flowing to the floor heating inlet end. Since the floor heating outlet water temperature is lower than the floor heating inlet water temperature, the floor heating inlet water temperature can be reduced by adding the low-temperature floor heating outlet water to the floor heating inlet end to achieve T6 = Td.

[0100] On the basis of the control according to Table 3, the air source heat pump unit 110 continuously provides high-temperature hot water for the radiator end 141 through the fully closed three-way valve 2, and finally T5 = Tn can be achieved, so that hot water at different temperatures can be provided for different ends.

[0101] In one embodiment, after obtaining the heating mode and temperature detection data of the heating control system, the method further includes:

[0102] When the heating mode is the floor heating mode, according to the comparison result between the water tank temperature and the preset floor heating temperature, control the working state of the air source heat pump unit 110 in the heating control system, and the on-off states of each water pump and switch valve in the hydraulic module 130 in the heating control system, so that the hot water temperature provided by the water tank for the floor heating end 142 meets the preset floor heating temperature; or,

[0103] When the heating mode is the radiator mode, according to the comparison result between the water tank temperature and the preset radiator temperature, control the working state of the air source heat pump unit 110 in the heating control system, and the on-off states of each water pump and switch valve in the hydraulic module 130 in the heating control system, so that the hot water temperature provided by the water tank for the radiator end 141 meets the preset radiator temperature.

[0104] Specifically, when the heating mode is the floor heating mode, it means that the user only uses the floor heating. Then, according to the comparison result between the water tank temperature and the preset floor heating temperature, control the working state of the air source heat pump unit 110, and the on-off states of each water pump and switch valve, so that the floor heating inlet water temperature reaches the preset floor heating temperature.

[0105] When the heating mode is the radiator mode, it means that the user only uses the radiator. Then, according to the comparison result between the water tank temperature and the preset radiator temperature, control the working state of the air source heat pump unit 110, and the on-off states of each water pump and switch valve, so that the radiator inlet water temperature reaches the preset radiator temperature.

[0106] That is, when the user uses a single heating terminal, only the single temperature requirement of T6 = Td or T5 = Tn needs to be achieved.

[0107] In one embodiment, according to the comparison result between the water tank temperature and the preset floor heating temperature, the working state of the air source heat pump unit 110 in the heating control system and the on-off states of each water pump and switch valve in the hydraulic module 130 in the heating control system are controlled, including at least one of the following:

[0108] When the water tank temperature is greater than the preset floor heating temperature, control the air source heat pump unit 110 to be in a shutdown state, close the first water pump, the third water pump, the two-way valve, the three-way confluence valve, the second three-way diversion valve, and open the second water pump and the first three-way diversion valve;

[0109] When the water tank temperature is less than or equal to the preset floor heating temperature and the temperature difference between the preset floor heating temperature and the water tank temperature is less than the first preset temperature difference, control the air source heat pump unit 110 to maintain its current operating state, close the first water pump, the two-way valve, the three-way confluence valve, the second three-way diversion valve, keep the on-off state of the third water pump unchanged, and open the second water pump and the first three-way diversion valve;

[0110] When the water tank temperature is greater than the temperature threshold and the temperature difference between the preset floor heating temperature and the water tank temperature is greater than or equal to the first preset temperature difference, control the air source heat pump unit 110 to be in an operating state, close the first water pump, the two-way valve, the three-way confluence valve, the second three-way diversion valve, and open the third water pump, the second water pump and the first three-way diversion valve;

[0111] When the water tank temperature is less than or equal to the temperature threshold, control the air source heat pump unit 110 to be in an operating state, close the first water pump, the second water pump, the two-way valve, the three-way confluence valve, the second three-way diversion valve, and open the third water pump and the first three-way diversion valve;

[0112] Wherein, when the second water pump is opened, the opening degree of the second water pump is adjusted according to the second preset adjustment scheme.

[0113] Specifically, when Ts > Td, it means that the water tank temperature is higher than the preset floor heating temperature. There is no need to activate the air source heat pump unit 110. Only the water tank is used to supply heat to the floor heating terminal 142. Therefore, the air source heat pump unit 110 is not turned on. The first water pump (water pump 4) is turned off to prohibit heating the radiator terminal 141. The third water pump (water pump 13) is turned off to prevent the water tank from supplying water to the air source heat pump unit 110 and causing a reduction in the hot water in the water tank. The two-way valve 3 is turned off to prohibit the water tank from heating the radiator terminal 141. The first three-way diverter valve (three-way valve 2) in the fully open state only conducts the XZ vertical branch, and there is no water flow in the XY horizontal branch. The three-way confluence valve (three-way valve 8) in the fully closed state only conducts the UW horizontal branch, and there is no water flow in the VW vertical branch. The second water pump (water pump 7) is used to drive all the water discharged from the water tank through the three-way valve 8 to heat the floor heating terminal 142. The second three-way diverter valve (three-way valve 12) in the fully closed state is used to return all the floor heating water to the water tank through the horizontal branch.

[0114] When Td - Δt < Ts ≤ Td, that is, Td - Ts < Δt and Ts ≤ Td, it means that the floor heating inlet water temperature is lower than the preset floor heating temperature, but the floor heating inlet water temperature is close to the preset floor heating temperature. Then, the air source heat pump unit 110 is controlled to maintain its original state to avoid frequent start and stop of the unit. The first water pump (water pump 4) is turned off to prohibit heating the radiator terminal 141. The third water pump (water pump 13) is kept in its original state to match the current working state of the air source heat pump unit 110. The two-way valve 3 is turned off to prohibit the water tank from heating the radiator terminal 141. The first three-way diverter valve (three-way valve 2) in the fully open state only conducts the XZ vertical branch, and there is no water flow in the XY horizontal branch. The three-way confluence valve (three-way valve 8) in the fully closed state only conducts the UW horizontal branch, and there is no water flow in the VW vertical branch. The second water pump (water pump 7) is used to drive all the water discharged from the water tank through the three-way valve 8 to heat the floor heating terminal 142. The second three-way diverter valve (three-way valve 12) in the fully closed state is used to return all the floor heating water to the water tank through the horizontal branch.

[0115] When Tc < Ts ≤ Td - Δt, that is, Δt ≤ Td - Ts, indicating that the temperature difference between the preset floor heating temperature and the water tank temperature is large, it is necessary to activate the air source heat pump unit 110. The air source heat pump unit 110 ensures its operating state. Through the three-way valve 2 in the fully open state, all the water output from the units is provided to the water tank through the XZ vertical branch to heat the water tank. The first water pump (water pump 4) is closed to prohibit heating the radiator end 141. The third water pump (water pump 13) is turned on to enable the water tank to supply the water inlet to the air source heat pump unit 110 to achieve circulating heating of the water tank. The two-way valve 3 is closed to prohibit the water tank from heating the radiator end 141. The first three-way diversion valve (three-way valve 2) in the fully open state only conducts the XZ vertical branch, and there is no water flow in the XY horizontal branch. While the three-way confluence valve (three-way valve 8) in the fully closed state only conducts the UW horizontal branch, and there is no water flow in the VW vertical branch. The second water pump (water pump 7) is used to drive all the water output from the water tank passing through the three-way valve 8 to heat the floor heating end 142. The second three-way diversion valve (three-way valve 12) in the fully closed state is used to return all the floor heating water to the water tank through the horizontal branch.

[0116] When Ts ≤ Tc, indicating that the water tank temperature is too low, the first water pump (water pump 4), the second water pump (water pump 7), the two-way valve 3, the three-way valve 8, and the three-way valve 12 are closed. Only the water pump 13 and the three-way valve 2 are turned on to prevent the end water circuit from starting circulation. After the air source heat pump unit 110 heats up the water tank temperature first, the end circulation is then started. In weather with high humidity, the unit frosts quickly. This measure can quickly increase the water temperature flowing through the unit and make the unit defrost faster.

[0117] That is, when the user only turns on the floor heating, the control is carried out according to Table 4 below:

[0118]

[0119] Table 4

[0120] After the control is carried out according to Table 4, when the control duration reaches the preset duration, the step of adjusting the second water pump according to the second preset adjustment scheme is executed. That is, when Δtd > 6°C, the opening of the second water pump is increased by 5%; when Δtd < 3°C, the opening of the second water pump is decreased by 5%; when Δtd = 3 - 6°C, the opening of the second water pump remains unchanged. To dynamically balance the heat dissipation effect of the floor heating end 142 and the energy consumption of the second water pump.

[0121] In one embodiment, when the heating mode is the radiator mode, according to the comparison result between the water tank temperature and the preset radiator temperature, the working state of the air source heat pump unit 110 in the heating control system, and the on / off states of each water pump and switch valve in the hydraulic module 130 in the heating control system are controlled, including at least one of the following:

[0122] When the temperature of the water tank is greater than the preset radiator temperature, control the air source heat pump unit 110 to be in a shutdown state, close the second water pump, the third water pump, the three-way confluence valve, and the second three-way diverter valve, and open the two-way valve, the first water pump, and the first three-way diverter valve;

[0123] When the temperature of the water tank is less than or equal to the preset radiator temperature and the temperature difference between the preset radiator temperature and the water tank temperature is less than the first preset temperature difference, control the air source heat pump unit 110 to maintain its current operating state, close the second water pump, the three-way confluence valve, and the second three-way diverter valve, keep the switch state of the third water pump unchanged, and open the first water pump, the two-way valve, and the first three-way diverter valve;

[0124] When the temperature of the water tank is greater than the temperature threshold and the temperature difference between the preset radiator temperature and the water tank temperature is greater than or equal to the first preset temperature difference, control the air source heat pump unit 110 to be in an operating state, close the second water pump, the three-way confluence valve, and the second three-way diverter valve, and open the third water pump, the two-way valve, the first water pump, and the first three-way diverter valve;

[0125] When the temperature of the water tank is less than or equal to the temperature threshold, control the air source heat pump unit 110 to be in an operating state, close the first water pump, the second water pump, the two-way valve, the three-way confluence valve, and the second three-way diverter valve, and open the third water pump and the first three-way diverter valve;

[0126] Among them, when the first water pump is opened, adjust the opening degree of the first water pump according to the second preset adjustment scheme.

[0127] Specifically, when Ts > Tn, it means that the temperature of the water tank is higher than the preset radiator temperature. There is no need to activate the air source heat pump unit 110. Only the water tank is used to supply heat to the radiator end 141. Therefore, the air source heat pump unit 110 is not turned on. The second water pump (water pump 7) is turned off to prevent heating the floor heating end 142. The third water pump (water pump 13) is turned off to prevent the water tank from supplying water to the air source heat pump unit 110 and causing a reduction in the hot water in the water tank. The two-way valve 3 is opened to allow the water tank to supply heat to the radiator end 141. The first three-way shunt valve (three-way valve 2) in the fully open state only conducts the XZ vertical branch, and there is no water flow in the XY horizontal branch. That is, all the unit's outlet water flows through the three-way valve 2 to the water tank. The three-way confluence valve (three-way valve 8) in the fully closed state only conducts the UW horizontal branch, and there is no water flow in the VW vertical branch. The second three-way shunt valve (three-way valve 12) in the fully closed state is used to return all the radiator outlet water to the water tank through the horizontal branch. Since the water pump 7 is turned off, there is no water flow circulation in the floor heating end 142. Only the first water pump (water pump 4) drives all the water tank outlet water passing through the two-way valve 3 to heat the radiator end 141.

[0128] When Td - Δt < Ts ≤ Tn, that is, Tn - Ts < Δt and Ts ≤ Tn, it means that the inlet temperature of the radiator is lower than the preset radiator temperature, but the inlet temperature of the radiator is close to the preset radiator temperature. Then, control the air source heat pump unit 110 to maintain its original state to avoid frequent start and stop of the unit. The second water pump (water pump 7) is turned off to prevent heating the floor heating end 142. Keep the third water pump (water pump 13) in its original state to match the current working state of the air source heat pump unit 110. Open the two-way valve 3 to allow the water tank to supply heat to the radiator end 141. After a period of time, make T5 = Tn.

[0129] When Tc < Ts ≤ Tn - Δt, that is, Δt ≤ Tn - Ts, it means that the temperature difference between the preset radiator temperature and the water tank temperature is large. Then, it is necessary to activate the air source heat pump unit 110. The air source heat pump unit 110 ensures its operating state. All the unit's outlet water is supplied to the water tank through the XZ vertical branch by the fully open three-way valve 2 to heat the water tank. The second water pump (water pump 7) is turned off to prevent heating the floor heating end 142. The third water pump (water pump 13) is turned on to allow the water tank to supply water to the air source heat pump unit 110 to achieve circulating heating of the water tank. The two-way valve 3 is opened to allow the water tank to supply heat to the radiator end 141.

[0130] When Ts ≤ Tc, it indicates that the water temperature in the water tank is too low. The first water pump (water pump 4), the second water pump (water pump 7), the two-way valve 3, the three-way valve 8, and the three-way valve 12 are closed. Only the water pump 13 and the three-way valve 2 are opened, so that the end water circuit does not start circulating. After the air source heat pump unit 110 heats up the water temperature in the water tank first, the end circulation is then started. On days with high humidity, the unit frosts quickly. This measure can quickly increase the water temperature flowing through the unit, enabling the unit to defrost faster.

[0131] That is, when the user only turns on the floor heating, the control is carried out according to Table 5 below:

[0132]

[0133] Table 5

[0134] After the control is carried out according to Table 5, when the control duration reaches the preset duration, the step of adjusting the first water pump according to the second preset adjustment scheme is executed. That is, when △tn > 6°C, the opening degree of the first water pump is increased by 5%; when △tn < 3°C, the opening degree of the first water pump is decreased by 5%; when △tn = 3 - 6°C, the opening degree of the first water pump remains unchanged. To dynamically balance the heat dissipation effect of the radiator end 141 and the energy consumption of the first water pump.
