Description

Technical Field

[0001] The utility model belongs to the technical field of heating and cooling systems, and specifically relates to an intelligent Internet of Things transmission and distribution center. Background Art

[0002] The distribution center is also called the distribution station, which is suitable for large-area, multi-terminal heating and cooling systems. It is usually installed between the heat source and the terminal equipment to connect the heat source and the terminal. The heat source distributes water to multiple terminals through the distribution center to achieve the circulation and control of heating / cooling in the system. The distribution center is mainly composed of a manifold and a mixing center. The primary water is mixed through the mixing center, and the water temperature required for the secondary can be output, and the water supply temperature of the secondary terminal can be controlled to achieve energy saving and comfort. The distribution center thus circulates and controls the temperature and flow of the system medium.

[0003] However, the inventors have found through research that the existing distribution centers have the following problems:

[0004] (1) The water mixing center and the distribution center are mostly separate, and need to be reassembled and connected when in use, which is relatively complicated; and the water mixing center can only be connected to the terminal after being connected to the distribution center. The water mixing center has only one interface, so it can only output one water temperature and one terminal; (2) The core of the existing pump station's water mixing device is to control and adjust the water temperature, and the flow is not coupled, resulting in water grabbing between the primary and secondary sides, unstable flow, and increased selection of secondary side water pumps. Utility Model Content

[0005] The utility model aims to provide an intelligent Internet of Things distribution center, which has high functional integration, is compatible with a variety of terminals and water temperatures, and meets the water temperature requirements of different terminals.

[0006] In order to achieve the above utility model purpose, the technical solution of the utility model is as follows:

[0007] An intelligent Internet of Things distribution center includes a distribution center body, which includes a water collector, a water distributor and a water mixing device arranged between the water distributor and the water collector. The water mixing device includes a water mixing tank, one side of the water mixing tank and the water collector and the water distributor together form a primary water flow circulation system, and the other side of the water mixing tank and the water collector and the water distributor together form a secondary water flow circulation system.

[0008] The intelligent Internet of Things distribution center of the utility model has high functional integration, can output multiple terminals and water temperatures to meet the water temperature requirements of different terminals, and there are multiple options for the number of interfaces for each terminal; at the same time, the water mixing device of the utility model is arranged between the water collector and the water divider, one side of the water mixing tank and the water collector and the water divider together form a primary water flow circulation system, and the other side of the water mixing tank and the water collector and the water divider together form a secondary water flow circulation system, eliminating the coupling relationship between the primary side and the secondary side, so that the primary water flow circulation system and the secondary water flow circulation system do not affect each other, thereby realizing the decoupling function.

[0009] In the above-mentioned intelligent Internet of Things distribution center, the water collector is provided with a plurality of return water end assemblies with different temperatures including a primary return water end assembly and a secondary return water end assembly, the water distributor is provided with a plurality of water supply end assemblies with different temperatures including a primary water supply end assembly and a secondary water supply end assembly, and a circulating water pump is provided on one side of the mixing tank forming the secondary water flow circulation system.

[0010] The primary water return terminal assembly, one side of the mixing tank and the primary water supply terminal assembly form a primary water flow circulation system, and the secondary water return terminal assembly, one side of the mixing tank, the circulating water pump and the secondary water supply terminal assembly form a secondary water flow circulation system.

[0011] The utility model ensures the formation of a secondary water circulation system of the water mixing tank by setting a circulation pump on the side; the three-way proportional regulating valve in the traditional water mixing device has a small diameter, and the internal water flow has a large angle of turning, so the water resistance is relatively much larger, so the performance requirements of the water pump of the secondary water circulation system are relatively high, which increases energy consumption; while the inner diameter of the water mixing tank is very large, and the water resistance is much smaller than that of the traditional manifold, which reduces the performance requirements of the secondary system circulation water pump, thereby reducing energy consumption. In addition, the utility model can allow the primary water circulation system and the secondary water circulation system to operate independently without interfering with each other, solving the contradiction between the different water volume requirements of the two, and can also mix the primary water supply with the secondary return water to adjust the water temperature of the secondary system.

[0012] In the above-mentioned intelligent Internet of Things distribution center, the water mixing tank is provided with a primary water supply interface and a primary return water interface connected to the primary water flow circulation system, and is also provided with a secondary return water interface and a secondary water supply interface connected to the secondary water flow circulation system. The water mixing device also includes a water mixing valve, which is connected to the primary return water interface.

[0013] The utility model arranges a mixing valve at the primary side return water port of the mixing valve, and adjusts the mixing ratio of the primary side supply water and the secondary side return water by controlling the valve core opening, so as to achieve the purpose of adjusting the secondary side supply water temperature, which is more economical and energy-saving to use.

[0014] In the above-mentioned intelligent Internet of Things distribution center, the water mixing device also includes an exhaust valve, which is arranged on the top of the water mixing tank and controls the exhaust of the gas inside the water mixing tank.

[0015] Because the internal space of the mixing tank is large, the flow rate of water will decrease when passing through; at the same time, the gas inside the system is more likely to gather inside the tank to produce a large number of bubbles. Therefore, the utility model facilitates exhaust by placing an exhaust valve on the top of the mixing tank, thereby further reducing energy consumption.

[0016] The water mixing tank is also provided with a pressure sensor which can detect the system pressure and transmit the detection data to the intelligent control center.

[0017] In the above-mentioned intelligent Internet of Things distribution center, the water mixing valve includes an electrothermal actuator and a valve core, and the water mixing valve controls the valve core through the electrothermal actuator.

[0018] The traditional three-way proportional regulating valve uses an electric regulating valve to control the system water temperature. The electric regulating valve operates frequently, makes a lot of noise and is expensive. The water mixing regulating valve of the utility model uses an electric heating actuator to drive the valve core. The working noise of the electric heating actuator is very small, so the overall water mixing device does not make much noise; the price of the three-way proportional regulating valve on the market is much higher than that of the electric heating actuator, so the cost of this water mixing device is lower than that of the traditional three-way proportional regulating actuator. The electric heating actuator can be selected from commercially available products according to actual needs.

[0019] In the above-mentioned intelligent Internet of Things distribution center, the return water terminal component also includes a wind disk return water terminal component, a dehumidification fresh air return water terminal component and a bypass return, and the water supply terminal component also includes a wind disk water supply terminal component, a dehumidification fresh air water supply component and a bypass supply.

[0020] The secondary water return terminal assembly is a floor heating water return terminal assembly, and the secondary water supply terminal assembly is a floor heating water supply terminal assembly. The utility model is compatible with a variety of terminals and water temperatures, meeting the water temperature requirements of different terminals, and there are multiple options for the number of interfaces for each terminal, with high functional integration and easy use.

[0021] In the above-mentioned intelligent Internet of Things distribution center, it also includes an intelligent control center. The return water terminal component and the water supply terminal component are respectively provided with multiple temperature sensors. The return water terminal component is also provided with at least one control valve. The temperature sensor and the control valve are both connected to the intelligent control center.

[0022] The temperature sensor and the control valve can be commercially available products.

[0023] The input and output at the end of the distribution center have independent regulating valves and control valves, and these control valves are uniformly controlled by the intelligent control center of the distribution center, which can meet various needs and is easy to use.

[0024] In the above-mentioned intelligent Internet of Things distribution center, it also includes a distribution center shell with a closed door panel, the distribution center body and the intelligent control center are arranged inside the distribution center shell, the intelligent control center is detachably connected to the inside of the distribution center shell, and the intelligent control center is arranged above the distribution center body.

[0025] Preferably, the intelligent control center is connected to the housing of the distribution center via a pull-out junction box.

[0026] Traditional equipment control boxes require the removal of the inspection panel for operation, and the operating space is usually small, which makes operation very inconvenient. In this solution, the intelligent control center is connected to the inside of the distribution center shell by a pull-out method, such as a pull-out junction box. When operation is required, just pull out the box and hang it outside the body, which is convenient for early wiring and subsequent maintenance. There is also enough operating space, and the main power switch on the outside of the junction box can ensure personnel safety.

[0027] In the above-mentioned intelligent Internet of Things distribution center, the distribution center shell also includes a hanging plate, a bracket and a support plate. The hanging plate and the support plate are plugged together, and the support plate and the lower end of the distribution center shell are matched.

[0028] Traditional distribution station installation methods include ceiling-mounted and wall-mounted. The ceiling-mounted type needs to be installed on the ceiling, which is the most complicated. The wall-mounted type uses expansion screws to fix the entire product to the wall. When installing the expansion screws, the installer needs to lift it all the time, and the same is true when disassembling the machine. This distribution center can be installed conveniently and quickly by installing fixed components. Before installing the whole machine, first fix the bracket and support plate on the wall to the appropriate position, then lift the entire distribution center shell, align the notch of the hanging plate with the bracket, and then drive the fixing screws into the bottom, saving installation time and reducing installation costs.

[0029] In the above-mentioned intelligent Internet of Things distribution center, the main body of the distribution center also includes a main pipe component and a branch pipe component, the main pipe component is respectively connected to multiple pipe ports, the multiple pipe ports are arranged on any one side of the two sides of the distribution center shell, and the branch pipe component includes an upper pipe and a lower pipe.

[0030] The utility model has a large adjustment space, and the position of the water mixing device between the manifold can be changed left and right, which can change the number of primary and secondary terminal devices, adapt to different scenes and customer usage needs, distribute on demand, save energy and reduce consumption, and provide users with better use effects. In addition, the connection direction of the main component of the intelligent Internet of Things transmission and distribution center has left connection and right connection, and the terminal branch connection component has upper connection or lower connection, which can meet the connection needs of different sites and has a higher adaptability to the site environment.

[0031] Compared with the prior art, the beneficial effects of the utility model are embodied in:

[0057] Specific implementation modes are listed below to further explain the technical solution of the utility model in detail.

[0058] Example 1

[0059] like Figure 1 and Figure 2 As shown, this embodiment provides an intelligent Internet of Things distribution center, which includes a distribution center body 1, an intelligent control center 2 and a distribution center shell 3 provided with a closed door panel 31. The distribution center body 1 and the intelligent control center 2 are arranged inside the distribution center shell 3, and the intelligent control center 2 is detachably connected to the inside of the distribution center shell 3. The intelligent control center 2 is arranged above the distribution center body 1.

[0060] like Figure 3 As shown, the intelligent Internet of Things distribution center of this embodiment has high functional integration, can output a variety of terminals and water temperatures, meet the water temperature requirements of different terminals, and there are multiple options for the number of interfaces of each terminal. The water collector 11 is provided with a variety of return water terminal components with different temperatures, and the water distributor 13 is provided with a variety of water supply terminal components with different temperatures. The return water terminal components of this embodiment include a primary return water terminal component 111, a secondary return water terminal component 112, a fan disk return water terminal component 113, a dehumidification fresh air return water terminal component 114 and a bypass return 115, and the water supply terminal component includes a primary water supply terminal component 131, a secondary water supply terminal component 132, a fan disk water supply terminal component 133, a dehumidification fresh air water supply component 134 and a bypass supply 135. The secondary return water terminal component 112 is a floor heating return water terminal component, and the secondary water supply terminal component 132 is a floor heating water supply terminal component. The floor heating water return terminal assembly and the floor heating water supply terminal assembly are connected to the branch of the floor radiation cooling and heating; the fan disk water return terminal assembly 113 and the fan disk water supply terminal assembly 133 are connected to the branch of the fan coil; the dehumidification fresh air water return terminal assembly 114 and the dehumidification fresh air water supply assembly 134 are connected to the branch of the dehumidification equipment; the bypass return 115 and the bypass supply 135 form a loop. When the water flow in the system is insufficient, the bypass function is turned on to protect the host and prevent the host from frequent start and stop. This embodiment has 6-way floor heating, 2-way fan disk, 1-way dehumidification and 1-way bypass.

[0061] The utility model is compatible with a variety of terminals and water temperatures, meeting the water temperature requirements of different terminals, and there are a variety of options for the number of interfaces for each terminal, with high functional integration and easy use.

[0062] In the return water terminal assembly: the primary return water terminal assembly 111 includes a copper body and a primary return water side temperature sensor 111a, which detects the system return water temperature; the secondary return water terminal assembly 112 includes a valve body and a secondary return water side temperature sensor 112a, which detects the secondary return water temperature; the dehumidification fresh air return water terminal assembly 114 includes a dehumidification fresh air return water connector 114a.

[0063] In the water supply terminal assembly: the primary water supply terminal assembly 131 includes a copper body and a primary water supply side temperature sensor 131a to detect the system water supply temperature; the secondary water supply terminal assembly 132 includes a valve body and a secondary water supply side temperature sensor 132a to detect the secondary water supply temperature; the dehumidification fresh air water supply assembly 134 includes a dehumidification fresh air water supply connector 134a. The water supply terminal assembly of this embodiment also includes a secondary water supply regulating valve 136 to control the secondary water supply water flow. The temperature sensor and the control valve are both connected to the intelligent control center 2.

[0064] The input and output at the end of the distribution center have independent regulating valves and control valves, and these control valves are uniformly controlled by the intelligent control center 2 of the distribution center, which can meet various needs and is easy to use.

[0065] Combination Figure 3 As shown, the main body 1 of the distribution center of this embodiment includes a water collector 11, a water distributor 13, and a water mixing device 12 disposed between the water distributor 13 and the water collector 11. The water mixing device 12 includes a water mixing tank 121, one side of the water mixing tank 121 and the water collector 11 and the water distributor 13 together form a primary water flow circulation system, and the other side of the water mixing tank 121 and the water collector 11 and the water distributor 13 together form a secondary water flow circulation system.

[0066] The water mixing device 12 is arranged between the water collector 11 and the water divider 13. One side of the water mixing tank 121 and the water collector 11 and the water divider 13 together form a primary water flow circulation system, and the other side of the water mixing tank 121 and the water collector 11 and the water divider 13 together form a secondary water flow circulation system, eliminating the coupling relationship between the primary side and the secondary side, so that the primary water flow circulation system and the secondary water flow circulation system do not affect each other, thereby realizing the decoupling function.

[0067] A circulating water pump 122 is arranged on one side of the mixing tank 121 forming a secondary water circulation system. The secondary return water terminal assembly 112, one side of the mixing tank 121, the circulating water pump 122 and the secondary water supply terminal assembly 132 form a secondary water circulation system.

[0068] A circulation pump is arranged on the side to ensure the formation of a secondary water circulation system of the mixing tank 121; the three-way proportional regulating valve in the traditional water mixing device 12 is not large, and the internal water flow has a large angle of turning, the water resistance is relatively much larger, so the performance requirements of the water pump of the secondary water circulation system are relatively high, which increases the energy consumption; while the inner diameter of the mixing tank 121 is large, and the water resistance is much smaller than that of the traditional manifold 11, which reduces the performance requirements of the secondary system circulation water pump 122, thereby reducing energy consumption.

[0069] like Figure 4 As shown, the water mixing tank 121 is provided with a primary water supply interface 121d and a primary water return interface 121c connected to the primary water circulation system, and is also provided with a secondary water return interface 121e and a secondary water supply interface 121f connected to the secondary water circulation system.

[0070] The water mixing device 12 also includes Figure 5 The mixing valve 123 shown in the figure includes an electrothermal actuator 123a, a mixing valve body 123b, a baffle 123c, a primary return water port 123d of the mixing tank, and a valve core 123e 123e. The mixing valve 123 is connected to the primary return water port 121c. The mixing valve 123 includes an electrothermal actuator 123a and a valve core 123e. The mixing valve 123 controls the valve core 123e through the electrothermal actuator 123a. By controlling the opening of the valve core 123e, the mixing ratio of the primary side water supply and the secondary side return water is adjusted to achieve the purpose of adjusting the secondary side water supply temperature, which is more economical and energy-saving to use.

[0071] like Figure 6 As shown, the electric heating actuator 123a is not opened, the valve core 123e is supported by the electric heating actuator 123a, and the water inlet of the mixing valve body 123b is blocked. At this time, the floor heating water cannot flow out and can only circulate internally; Figure 7 As shown, the electric actuator 123a is turned on, and the valve core 123e is pulled up by the electric actuator 123a. At this time, the water mixing valve 123 is opened, and the floor heating water can enter the water mixing valve 123 and participate in the system water circulation; the opening of the valve core 123e is controlled by the electric actuator 123a. When cooling in summer, the valve core 123e is opened to mix the low-temperature cold water supplied by the primary side and the high-temperature cold water returned by the secondary side. By controlling the opening of the valve core 123e by the electric actuator 123a, any temperature between the primary side water supply and the secondary side return water can be mixed; when heating in winter, the valve core 123e is opened, and the high-temperature hot water supplied by the primary side and the low-temperature hot water returned by the secondary side are mixed. By controlling the opening of the valve core 123e by the electric actuator 123a, any temperature between the primary side water supply and the secondary side return water can be mixed.

[0072] Because the internal space of the mixing tank 121 is large, the flow rate of water will decrease when passing through; at the same time, the gas inside the system is more likely to gather inside the tank to produce a large number of bubbles. Therefore, the utility model controls the discharge of the gas inside the mixing tank 121 by placing an exhaust valve 124 on the top of the mixing tank 121. The mixing tank 121 is provided with an exhaust valve interface 121a that cooperates with the exhaust valve.

[0073] The water mixing tank 121 is also provided with a pressure sensor 125. The pressure sensor 125 can detect the system pressure and transmit the detection data to the intelligent control center 2. The water mixing tank 121 is provided with a pressure sensor interface 121b that cooperates with the pressure sensor 12.

[0074] like Fig.10 and Fig.11 As shown, in this solution, the intelligent control center 2 is connected to the inside of the distribution center shell 3 by a pull-out connection, and a pull-out junction box can be used, for example: when operation is needed, just pull out the box and hang it outside the body, which is convenient for early wiring and subsequent maintenance, and the operating space is sufficient. The main power switch on the outside of the junction box can ensure the safety of personnel.

[0075] like Fig.15 , Fig.16 and Fig.17 As shown, the distribution center housing 3 of this embodiment further includes a hanging plate 32, a bracket 33 and a support plate 34. Fig.12 , Fig.13 and Fig.14 As shown, the hanging plate 32 and the support plate 34 are plugged together, and the support plate 34 is matched with the lower end of the distribution center housing 3. Before installing the whole machine, the bracket 33 and the support plate 34 are fixed to the wall to a suitable position, and then the distribution center housing 3 is lifted up, the notch of the hanging plate 32 is aligned with the bracket 33, and then the fixing screws are driven into the bottom, which saves installation time and reduces installation costs.

[0076] The distribution center body 1 also includes a main pipe assembly 14 and a branch pipe assembly 15. The main pipe assembly 14 is respectively connected to a plurality of pipe ports 35. The plurality of pipe ports 35 are arranged on any one of the two sides of the distribution center shell 3. The branch pipe assembly 15 includes an upper pipe and a lower pipe. The pipe connection direction of the main pipe assembly 14 of the distribution center of the present intelligent Internet of Things is left-connected and right-connected. The corresponding distribution center shell 33 is provided with a pipe port 35 on the left or right side. The pipe connection direction of the main pipe assembly 14 of the present embodiment is right-connected.
