[0042] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0043] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0044] Common water systems typically use a water pump within a water chiller to drive the water throughout the system, achieving either cooling or heating. (See reference...) Figure 2 , Figure 2 This is a connection diagram of an integrated control system for an existing water system. The entire water system can only use the built-in water pump BN in the water machine 10 to drive the water in the entire system. However, as the usage scenarios change, this single driving method is no longer suitable for all scenarios.

[0045] Therefore, based on the shortcomings of the above water system design methods, this application proposes an integrated control system for the water system: by connecting an external water pump module between the water supply end of the water turbine and the fan coil unit and the water distribution control module, the water in the entire system can be driven by both the water pump inside the water turbine and the water pump in the external water pump module when needed. Thus, the flow and head of the entire system can be controlled by the driving method of the internal and external water pumps, thereby avoiding the phenomenon that the method of driving only the water pump inside the water turbine cannot meet the needs of different usage scenarios of the water system. This integrated control system for the water system can control the flow and head of the entire system by the driving method of the internal and external water pumps, thereby improving the usage scenarios of the water system.

[0046] Based on this, embodiments of this application provide an integrated control system for a water system, referring to... Figure 1 , Figure 1 This is a schematic diagram of the framework of the first embodiment of the integrated control system of the water system of this application.

[0047] Reference Figure 1 This application provides an integrated control system for a water system, which includes:

[0048] The system includes a water heater 10, a terminal unit 40, and a water distribution control module 30. The floor heating element 42 and the fan coil unit 41 in the terminal unit 10 are connected to the water supply end of the water heater 10 via a water supply pipe. The water distribution control module 30 is connected between the floor heating element 42 and the water supply end of the water heater 10. The communication end of the water distribution control module 30 is connected to the communication end of the water heater 30 and the communication end of the fan coil unit 41.

[0049] An external water pump module 20 is connected to the communication terminal of the water machine 10. The external water pump module 20 is connected between the water supply terminal of the water machine 10 and the fan 41 and the water distribution control module 30.

[0050] For example, as the application scenarios of water systems continue to change, the requirements for pump control also differ in different scenarios. For instance, in primary systems, some require external booster pumps; in secondary systems, some have a single pump on the secondary side, while others have multiple pumps on the secondary side driving different areas or floors, and still others have multiple pumps on the secondary side driving different terminals—the most common being pumps driving fan coil units and underfloor heating. Therefore, based on these requirements, this application proposes an integrated control system for water systems to meet the usage needs in different scenarios.

[0051] In this embodiment, the integrated control system of the water system includes the original water heater 10, terminal unit 40, and manifold control module 30. The underfloor heating unit 42 and fan coil unit 41 in the terminal unit 10 are connected to the water supply end of the water heater 10 via water supply pipes. The manifold control module 30 is connected between the underfloor heating unit 42 and the water supply end of the water heater 10. The communication terminal of the manifold control module 30 is connected to the communication terminals of the water heater 30 and the fan coil unit 41. The water supply pipe includes an outlet pipe and a return pipe, which connect the water heater 10, terminal unit 40, and manifold control module 30 to form a normal water circulation loop. This allows for the normal use of the cold water generated by the water heater 10 for refrigeration or the hot water generated for heating. Further details can be found in the following section. Figure 3 , Figure 3This diagram illustrates a communication connection of the integrated control system for the water system in this application. The water distribution controller 31 in the water distribution control module 30, the hydraulic module 11 in the water turbine 10, and the fan coil unit 41 communicate via RS-485 communication, enabling the drive and control of the entire water system to achieve cooling and heating. The communication transmission and control logic are not detailed here. An external water pump module 20 is added to the integrated control system, connecting the external water pump module 20 to the water supply end of the water turbine 10, the fan coil unit 41, and the water distribution control module 30. When driving the hot and cold water in the system, both the pump in the external water pump module 20 and the built-in pump BN in the water turbine 10 can be used simultaneously to increase the overall system flow rate and head. This increased flow rate and head allows the system to be adapted to different scenarios, at least meeting the needs of high flow rate and high head scenarios, thus expanding the application scenarios of the water system.

[0052] It is worth noting that the external water pump module 20 can be connected to the water system for either the primary or secondary system, thereby expanding the different application scenarios of the primary or secondary system. For example, the primary system can meet the scenario of high flow rate and high head, while the secondary system may meet the scenario of high flow rate, high head, and independent drive by the external water pump. It can also meet the scenario of categorized or zoned drive of the terminal 40 based on the external water pump. Thus, the application scenarios of the water system can be expanded by connecting the external water pump module 20.

[0053] In this embodiment, an integrated control system for a water system is provided, including a water heater 10, a terminal unit 40, and a water distribution control module 30. The underfloor heating element 42 and the fan coil unit 41 in the terminal unit 10 are connected to the water supply end of the water heater 10 via water supply pipes. The water distribution control module 30 is connected between the underfloor heating element 42 and the water supply end of the water heater 10, and its communication terminal is connected to both the water heater 30 and the fan coil unit 41. An external water pump module 20 is also provided, with its communication terminal connected to the communication terminal of the water heater 10. The external water pump module 20 is connected between the water supply end of the water heater 10 and the fan coil unit 41 and the water distribution control module 30. This water system... The integrated control system connects an external water pump module 20 between the water supply end of the water turbine 10, the fan 41, and the water distribution control module 30. This allows the water pumps inside the water turbine 10 and the external water pump module 20 to drive the water in the entire system when needed. By using both internal and external water pumps to drive the entire system's flow and head, the system avoids the problem of relying solely on the water pumps inside the water turbine, which cannot meet the needs of different water system usage scenarios. This integrated control system improves the usability of the water system by using both internal and external water pumps to drive the entire system's flow and head.

[0054] Furthermore, based on the first embodiment of the integrated control system for the water system of this application described above, a second embodiment of the integrated control system for the water system of this application is proposed, with reference to... Figure 4 , Figure 4 This is a connection diagram of the first embodiment of the integrated control system of the water system of this application. When the water system is a primary system, the integrated control system of the water system includes a first buffer water tank 51, the water supply pipe includes an outlet pipe and a return pipe, and the water supply end of the water machine includes a return end HL and an outlet end CL.

[0055] The inlet of the first buffer water tank 51 is connected to the outlet of the fan 41 and the outlet of the water distribution control module 30 through the return water pipe HL. The external water pump module 20 is connected between the outlet of the first buffer water tank 51 and the return water end HL. The outlet end CL is connected to the inlet of the fan 41 and the inlet of the water distribution control module 30 through the outlet pipe.

[0056] Furthermore, the external water pump module 20 includes:

[0057] The first external water pump B1 has its inlet connected to the outlet of the first buffer water tank 51, its outlet connected to the return water end HL, and its communication end connected to the communication end of the water machine 10.

[0058] Furthermore, the communication terminal of the first external water pump B1 is connected to the communication terminal of the water distribution control module 30.

[0059] For example, the components of the integrated control system of the water system will be described first. Terminal 40 is a general term for remote indoor heat exchange equipment in a water-cooled or heated system, such as underfloor heating 42, fan coil unit 41, radiators, radiant panels, capillary networks, etc. This application will use fan coil unit 41 and underfloor heating 42 as examples. Underfloor heating 42 is a type of indoor heat exchange terminal, with coils arranged on the floor and filled with water for heating. Fan coil unit 41 is a type of indoor heat exchange terminal, a room indoor unit using water as a medium, exchanging heat with indoor air through water. It is worth noting that the entire system also includes a buffer water tank. Depending on the setting and connection location of the buffer water tank, the water system is divided into a primary system and a secondary system. The buffer water tank is a water storage container with two or more sets of inlet and outlet pipes, and has functions such as mixing, balancing flow, pressure stabilization, venting, and sewage discharge.

[0060] In this embodiment, based on the design idea of ​​the external water pump module 20 in the first embodiment, an external booster pump control scheme is proposed in the primary system. When the water system is a primary system, the integrated control system of the water system includes a first buffer water tank 51. At this time, the first buffer water tank 51 is set on the return water circuit between the entire water machine 10 and the fan 41, that is, the inlet and outlet water are connected through the return water pipe. At this time, in addition to controlling the original primary side water pump (i.e., the built-in water pump BN in the water machine 10), the integrated control system of the water system also needs a first external water pump B1. At this time, the inlet of the first external water pump B1 is connected to the outlet of the first buffer water tank 51, and the outlet of the first external water pump B1 is connected to the return water end HL (or it can be set on the outlet pipe). Furthermore, due to the communication control principle of the water turbine 10, the first external water pump B1 can be connected to the "host-external water pump control interface," meaning the communication end of the first external water pump B1 is connected to the communication end of the water turbine 10, or it can be connected to the "manifold control box-external water pump control interface," meaning the communication end of the first external water pump B1 is connected to the communication end of the manifold control module 30, thus enabling optional communication connections. In this case, the first external water pump B1 and the built-in water pump BN within the water turbine 10 can be used to drive the water in the entire system within the primary system, thereby expanding the application scenarios of the water system in the primary system by increasing the overall system flow rate and head.

[0061] Furthermore, based on the first and / or second embodiments of the integrated control system for the water system described above, a third embodiment of the integrated control system for the water system of this application is proposed, with reference to... Figure 5 , Figure 5 This is a connection diagram of the second embodiment of the integrated control system of the water system in this application. When the water system is a secondary system, the integrated control system of the water system includes a second buffer water tank 52.

[0062] The first inlet of the second buffer water tank 52 is connected to the outlet of the fan 41 and the outlet of the water distribution control module 30 via a return water pipe. The first outlet of the second buffer water tank 51 is connected to the return water end HL via a return water pipe. The second inlet of the second buffer water tank 51 is connected to the outlet end CL via an outlet water pipe. The second outlet of the second buffer water tank 51 is connected to the inlet of the fan 41 and the inlet of the water distribution control module 30 via an outlet water pipe. The external water pump module 20 is connected between the second outlet and the inlet of the fan 41 and the inlet of the water distribution control module 30.

[0063] Furthermore, when the water system is driven by a secondary-side single pump, the external water pump module 20 includes:

[0064] The second external water pump B2 has its inlet connected to the second outlet of the second buffer water tank 51, and its outlet connected to the inlet of the fan plate 41 and the inlet of the water distribution control module 30. The communication terminal of the second external water pump B2 is connected to the communication terminal of the water machine 10, or the communication terminal of the second external water pump B2 is connected to the communication terminal of the water distribution control module 30.

[0065] In this embodiment, based on the design idea of ​​the external water pump module 20 in the first embodiment, an external booster pump control scheme for the secondary system is proposed. When the water system is a secondary system, the integrated control system of the water system includes a second buffer water tank 52. At this time, the second buffer water tank 52 is set on the loop between the entire water machine 10 and the fan 41, that is, the water inlet and outlet are connected through the return water pipe and the outlet water pipe. At this time, in addition to controlling the original primary side water pump (i.e., the built-in water pump BN in the water machine 10), the integrated control system of the water system also needs a second external water pump B2. At this time, the inlet of the second external water pump B2 is connected to the second outlet of the second buffer water tank 51, and the outlet of the second external water pump B2 is connected to the inlet of the fan 41 and the inlet of the water distribution control module 30 (of course, it can also be set on the return water pipe). Furthermore, due to the communication control principle of the water turbine 10, the second external water pump B2 can be connected to the "main unit-external water pump control interface," meaning the communication end of the second external water pump B2 connects to the communication end of the water turbine 10, or it can be connected to the "manifold control box-external water pump control interface," meaning the communication end of the second external water pump B2 connects to the communication end of the manifold control module 30, thus enabling optional communication connections. In this case, the second external water pump B2 and the built-in water pump BN within the water turbine 10 can be used to drive the water in the entire system within the secondary system. This allows for an expansion of the water system's application scenarios within the secondary system by increasing the overall system flow rate and head.

[0066] In one embodiment, reference is made to Figure 6 , Figure 6 This is a connection diagram of the third embodiment of the integrated control system of the water system in this application. When the water system is driven by a secondary side pump, the external water pump module 20 includes:

[0067] The third external water pump B3 has its inlet connected to the second outlet of the second buffer tank 52, and its outlet connected to the inlet of the fan plate 41. The communication terminal of the third external water pump B3 is connected to the communication terminal of the water machine 10.

[0068] The fourth external water pump B4 has its inlet connected to the second outlet of the second buffer water tank 52, and its outlet connected to the inlet of the water distribution control module 30. The communication terminal of the fourth external water pump B4 is connected to the communication terminal of the water distribution control module 30.

[0069] In this embodiment, the secondary system may further include a secondary side fan coil unit 41 and a sub-pump drive scheme for the underfloor heating system 42. In this case, in addition to controlling the original primary side water pump, the water system also needs to control two external secondary side circulating water pumps, namely the third external water pump B3 and the fourth external water pump B4. The third external water pump B3 drives the fan coil unit 41, and the fourth external water pump B4 drives the underfloor heating system 42, thus realizing the separate driving of the fan coil unit 41 and the underfloor heating system 42 using different water pumps. Moreover, due to the communication control principle of the water turbine 10, in this secondary system, the third external water pump B3 is connected to the "host-external water pump control interface", that is, the communication terminal of the third external water pump B3 is connected to the communication terminal of the water turbine 10, and the fourth external water pump B4 is connected to the "manifold control box-external water pump control interface", that is, the communication terminal of the fourth external water pump B4 is connected to the communication terminal of the manifold control module 30. At this point, not only can the fourth external water pump B4, the third external water pump B3, and the built-in water pump BN in the water unit 10 be used to drive the water in the entire system, but the fourth external water pump B4 or the third external water pump B3 can also be selected to drive according to the needs, so as to realize the cooling and heating functions of the fan coil 41 or the underfloor heating 42. In this way, targeted drive control can be performed for scenarios that require the fan coil 41 or the underfloor heating 42 to work independently, thereby expanding the application scenarios of the water system in the secondary system.

[0070] In one embodiment, reference is made to Figure 7 , Figure 7 This is a connection diagram of the fourth embodiment of the integrated control system for the water system of this application. When the water system is driven by a secondary side partition, the external water pump module 20 includes:

[0071] Multiple fifth external water pumps B5 are connected. The inlet of the fifth external water pump B5 is connected to the second outlet of the second buffer water tank 52. The outlet of one fifth external water pump B5 is connected to the inlet of the air fan 41 and the inlet of the water distribution control module 30 in a certain area. The communication terminal of the fifth external water pump B5 is connected to the communication terminal of the water distribution control module 30 in that area.

[0072] In this embodiment, the secondary system may further include a secondary-side multi-zone pump drive scheme. In this case, in addition to controlling the original primary-side water pump, the water system also needs to control multiple external secondary-side circulating water pumps, namely the fifth external water pump B5. The inlet of the fifth external water pump B5 is connected to the second outlet of the second buffer tank 52, and the outlet of one fifth external water pump B5 is connected to the inlet of the fan coil unit 41 and the inlet of the manifold control module 30 in a certain area. This enables the use of different water pumps to drive the fan coil unit 41 and the underfloor heating 42 in a certain area. Moreover, due to the communication control principle of the water machine 10, in this secondary-side multi-zone pump drive scheme, the fifth external water pump B5 is connected to the "manifold control box - external water pump control interface", that is, the communication terminal of the fifth external water pump B5 is connected to the communication terminal of the manifold control module 30 in that area. At this point, not only can the fifth external water pump B5 and the built-in water pump BN in the water unit 10 be used to drive the water in the entire system, but the fifth external water pump B5 can also be selected according to needs to achieve the function of cooling and heating the fan coil 41 or the underfloor heating 42 in a certain area (for example, the first, second and third floors of a three-story building are divided into one area. If only the second floor needs to be heated, the fifth external water pump B5 corresponding to the second floor will be turned on to achieve the heating of the second floor). In this way, targeted drive control can be performed for scenarios where the fan coil 41 and the underfloor heating 42 in the corresponding area need to work separately, so as to expand the application scenarios of the water system in the secondary system.

[0073] In one embodiment, the control logic of the entire system is described in the following table, based on the design of the external water pumps in the primary and secondary systems described above:

[0074]

[0075]

[0076] Table 1

[0077] As shown in Table 1, the integrated control system of the water system can integrate the control scheme of the external booster pump of the primary system, the single pump drive scheme of the secondary side of the secondary system, the multi-zone pump drive scheme of the secondary side of the secondary system, and the fan coil floor heating pump drive scheme of the secondary system. Users can flexibly select the scheme according to the actual scenario and connect the wiring according to the control topology.

[0078] Based on the first, second, and / or third embodiments of the integrated control system for the water system described above, a fourth embodiment of the integrated control system for the water system of this application is proposed, wherein the water distribution control module 30 includes:

[0079] The communication terminal of the water distribution controller 31 is connected to the communication terminal of the water turbine 10 and the communication terminal of the fan 41.

[0080] The manifold 32 has a first outlet connected to the inlet of the underfloor heating system 42 via an outlet pipe, a first inlet connected to the outlet end CL via an outlet pipe, a second outlet connected to the return end HL via a return pipe, a second inlet connected to the outlet of the underfloor heating system 42 via a return pipe, and a controlled end connected to the control end of the manifold 32.

[0081] In this embodiment, the water distribution control module 30 includes a water distribution manifold 32, which is a device for distributing and collecting water flow, equipped with an electrically adjustable valve, and a water distribution controller 31, i.e., a water distribution manifold control box. This controller has the electrically adjustable valve control function of the water distribution manifold 32, can control an external water pump, and has communication interfaces with the water pump 10 and the fan coil unit 41. The communication terminal of the water distribution controller 31 is connected to the communication terminals of the water pump 10 and the fan coil unit 41. The first outlet of the water distribution manifold 32 is connected to the inlet of the underfloor heating system 42 via an outlet pipe, and the first inlet of the water distribution manifold 32 is connected to the outlet terminal CL via an outlet pipe. The second outlet of the water distribution manifold 32 is connected to the return terminal HL via a return pipe, and the second inlet of the water distribution manifold 32 is connected to the outlet of the underfloor heating system 42 via a return pipe. The controlled terminal of the water distribution manifold 32 is connected to the water distribution control... The control terminal of the device 31 is connected to the manifold 32, which is used to collect the water entering the underfloor heating 42 and adjust the output based on the manifold controller 31 to realize the control of the circulating water of the underfloor heating 42. At the same time, the manifold controller 31 has a communication interface with the water machine 10 and the fan coil 41, so it can communicate with the water machine 10 and the fan coil 41 to complete the control of the entire system. It can also control an external water pump to realize the control of the added external water pump to ensure the control accuracy of the entire system.

[0082] In one embodiment, the water dispenser 10 includes:

[0083] Water purifier and water pipes;

[0084] Built-in water pump BN, the inlet of built-in water pump BN is connected to the return water end HL through the water pipe of the water machine;

[0085] Heat exchanger 11, the input end of heat exchanger 11 is connected to the inlet of built-in water pump BN through water pipe, and the input end of heat exchanger 11 is connected to the outlet end CL through water pipe.

[0086] Hydraulic module 12 is connected to the control terminal of the built-in water pump BN, the communication terminal of the fan 41, the communication terminal of the external water pump module 20, and the communication terminal of the water distribution control module 30.

[0087] In this embodiment, the water chiller 10 refers to a system that exchanges heat with air through an internal compressed refrigerant circulation, and then exchanges heat with water through a water-fluoride heat exchanger to achieve either chilled water or hot water production. The water chiller 10 includes a hydraulic module 12, i.e., a hydraulic module electrical control. This hydraulic module electrical control can achieve wired communication with the fan coil unit 41 and the manifold control box, and can also control two water pumps. If the water chiller 10 has a built-in water pump, the hydraulic module electrical control can control one built-in water pump and one external water pump; if the water chiller does not have a water pump, the hydraulic module electrical control can control two external water pumps. At this time, the water heater 10 includes a built-in water pump BN, a heat exchanger 11, and a hydraulic module 12. The connection between the built-in water pump BN, the heat exchanger 11, and the hydraulic module 12 is used to generate chilled water or hot water, which is then circulated to the fan coil unit 41 and / or the underfloor heating system 42 to achieve cooling or heating. With the addition of the external water pump module 20, the flow rate and head of the entire water system can be expanded, thereby expanding the application scenarios of the water system.

[0088] It is worth noting that the water pipes of the water machine refer to the water pipes inside the water machine 10, which can be divided into return water pipes and outlet water pipes for the heat exchanger 11, so as to realize the function of circulating water returning to the heat exchanger 11 or driving the water out of the heat exchanger 11.

[0089] It is worth noting that the integrated control system of the water system may also include other hardware, which will not be described in detail here. The integrated control system of the entire water system can be set up in the usage scenario of multi-story villas, or in other usage scenarios that require the integrated control system of the water system, without limitation here.

[0090] The integrated control system for water systems provided in this application can solve the technical problem of limited application scenarios for water systems. Compared with the prior art, the beneficial effects of the integrated control system for water systems provided in this application are the same as those described in the above embodiments, and will not be repeated here.
