Description

Technical Field

[0001] This utility model relates to the field of hydraulic module technology, and in particular to a hydraulic module layout structure. Background Technology

[0002] In integrated HVAC and domestic water systems, the hydraulic module serves as a key distribution unit, undertaking the core function of connecting the heat pump unit, domestic water tank, buffer tank, and terminal water / heating equipment. Such modules typically integrate three major circulation systems simultaneously: a heat pump circulation system, a domestic water circulation system, and a heating water circulation system, resulting in a large number of internal pipes and a high degree of functional coupling.

[0003] In traditional layouts, the pipes of multiple systems become tangled due to the lack of zoning design. This not only occupies a lot of space, but also requires extensive disassembly of coverings for maintenance. Furthermore, when cleaning the pipes of the heat pump circulation system regularly, technicians need to manually open the top cover of the magnetic mud filter to inject cleaning agent, which poses a safety risk of high-temperature fluid splashing and results in low maintenance efficiency. At the same time, the electrical control box is not physically isolated from the pipes, making electronic equipment susceptible to heat conduction from the pipes and corrosion from condensate, which accelerates its deterioration.

[0004] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

In the description of this utility model, unless otherwise stated, "multiple" means two or more.

[0034] Please see Figures 1 to 8 As shown, this utility model provides a hydraulic module layout structure, including: a water receiving tray 2, and a first pipeline unit 1, a second pipeline unit 3, a third pipeline unit 4, and an electrical control box 5 disposed above the water receiving tray 2; the electrical control box 5 is located behind the first pipeline unit 1, the second pipeline unit 3, and the third pipeline unit 4; wherein the first pipeline unit 1, the second pipeline unit 3, and the third pipeline unit 4 are arranged side by side; each pipeline unit is partitioned on the water receiving tray 2, and the electrical control box 5 is designed to be separated from each pipeline unit, achieving a centralized spatial layout. The condensate generated by each pipeline unit is uniformly collected by the water receiving tray 2 and centrally drained through the bottom drain outlet, which is not shown in the attached drawing; combined with the separate design of the electrical control box 5, heat conduction in the pipes and condensate corrosion are effectively isolated, ensuring the reliability of electronic components. It should be noted that the electrical control box 5 has a built-in control circuit board, which is electrically connected to the components in each pipeline unit to achieve smooth operation of each pipeline unit. The specific electrical connection structure is prior art and will not be described further here.

[0035] The first pipeline unit 1 includes a magnetic mud filter 11, a first water pump 12, a first return water pipe 13, a four-way valve 14, and a water supply pipe 15, all located above the water receiving tray 2, as well as an external heat pump 6, a domestic water tank 7, a buffer water tank 8, and a water softening device 9. The inlet ends of the first return water pipe 13, the magnetic mud filter 11, the first water pump 12, and the heat pump 6 are connected sequentially along the pipeline, and the water supply pipe 15 is connected to the first return water pipe 13. The domestic water tank 7 includes a tank body 71 and a heat exchange component 72 located inside the tank body 71. The heat exchange component 72 is provided with a first water inlet 721 and a first water outlet 722. The buffer water tank 8 is provided with... The second water inlet 81 and the second water outlet 82; the outlet end of the heat pump 6 is connected to the first water inlet 721 and the second water inlet 81; the first return water pipe 13 is connected to the first water outlet 722 through the first branch pipe 131, and is connected to the second water outlet 82 through the second branch pipe 132; a four-way valve 14 is provided on the water supply pipe 15, and the four-way valve 14 is externally connected to a water softener 9, which is used to add cleaning agent to the water flowing into the first return water pipe 13; wherein, by controlling the four-way valve 14, the water in the water supply pipe 15 can selectively flow directly into the first return water pipe 13, or flow into the first return water pipe 13 after passing through the water softener 9;

[0036] In the above, such as Figure 8 As shown, the four-way valve 14 is existing technology. The four-way valve 14 has a first inlet 141, a second inlet 142, a first outlet 143, and a second outlet 144, and is equipped with three independent control valves: a third switching valve 145, a fourth switching valve 146, and a fifth switching valve 147. The valve state combination controls the flow direction: when the third switching valve 145 is open and the fourth switching valve 146 and the fifth switching valve 147 are closed, the first inlet 141 and the first outlet 143 form a connecting channel; when the fourth switching valve 146 is open and the third switching valve 145 and the fifth switching valve 147 are closed, the first inlet 141 and the second outlet 144 form a connecting channel; when the fifth switching valve 147 is open and the third switching valve 145 and the fourth switching valve 146 are closed, the second inlet 142 and the first outlet 143 form a connecting channel. In actual installation, the first inlet 141 is connected to the water supply pipe 15, the first outlet 143 is connected to the first return water pipe 13, the second outlet 144 is connected to the water inlet of the water softener 9, and the second inlet 142 is connected to the water outlet of the water softener 9.

[0037] In the first pipeline unit 1, the first water pump 12 drives water to flow through the heat pump 6 and heat it to form high-temperature water. The high-temperature water is then transported through the outlet of the heat pump 6 to the first inlet 721 of the heat exchange component 72. After heat exchange is completed in the tank 71 of the domestic water tank 7, it flows out from the first outlet 722. The cooled water flows through the first branch pipe 131 to the first return water pipe 13. Simultaneously, the high-temperature water is transported through the outlet of the heat pump 6 to the second inlet 81 of the buffer water tank 8. After heat exchange is completed in the buffer water tank 8, it flows out from the second outlet 82. The cooled water flows through the second branch pipe 132 to the first return water pipe 13. After heat exchange, the water flows through the first return water pipe 13 to the magnetic mud filter 11 for impurity adsorption. Finally, under the action of the first water pump 12, it re-enters the heat pump 6 for heating, forming a closed-loop cycle that continuously provides hot water to the heat exchange component 72 and the heating unit 44. Due to natural water loss in the first pipeline unit 1, water needs to be replenished through the water supply pipe 15.

[0038] During normal water replenishment, the four-way valve 14 switches to the open state of the third switch valve 145, and the fourth switch valve 146 and the fifth switch valve 147 are closed. At this time, the first inlet 141 and the first outlet 143 are connected, and the external water source is directly injected into the first return water pipe 13 through the water replenishment pipe 15 to achieve system water replenishment.

[0039] When it is necessary to remove scale from the first pipeline unit 1, switch the four-way valve 14 to the open state of the fourth switch valve 146 and the fifth switch valve 147, and close the third switch valve 145. At this time, the first inlet 141 is connected to the second outlet 144, and the second inlet 142 is connected to the first outlet 143. The water from the water supply pipe 15 first enters the water softener 9 through the second outlet 144. The water softener 9 injects cleaning agent into the water flow to form a mixed solution. This solution flows from the outlet of the water softener 9 through the second inlet 142 to the first outlet 143, and finally enters the first pipeline unit 1 through the first return water pipe 13. The suspended impurities formed after the cleaning agent dissolves the scale on the inner wall of the pipe are intercepted and discharged when flowing through the magnetic mud filter 11, realizing the simultaneous execution of water supply and cleaning, eliminating the high-temperature and pressurized operation risks caused by manually opening the magnetic mud filter 11 to add cleaning agent, and effectively improving maintenance efficiency.

[0040] The second pipeline unit 3 includes a second water pump 31, a second return water pipe 32, and a first outlet water pipe 33, all located above the water receiving tray 2, as well as an external water-using unit 34. The tank 71 is connected to the inlet of the water-using unit 34 via the first outlet water pipe 33 and to the outlet of the water-using unit 34 via the second return water pipe 32. The second water pump 31 is mounted on the second return water pipe 32. The tank 71 of the domestic water tank 7 serves as a storage and supply unit for clean water. It acts as an intermediate water storage link. High-temperature water flows through the heat exchange component 72, allowing its outer wall to efficiently exchange heat with the domestic water to heat it to a specified temperature. When the second water pump 31 starts, it drives the domestic water to flow through the first outlet water pipe 33, the water-using unit 34, and the second return water pipe 32, forming a closed-loop supply of domestic water. This continuously provides domestic water to the water-using unit 34, which can be a faucet, shower, etc.

[0041] The third piping unit 4 includes a third water pump 41 located above the water receiving pan 2, a third return water pipe 42, and a second outlet water pipe 43, as well as an external heating unit 44. The buffer water tank 8 is connected to the inlet of the heating unit 44 through the second outlet water pipe 43, and the third water pump 41 is located on the second outlet water pipe 43. The buffer water tank 8 is connected to the outlet of the heating unit 44 through the third return water pipe 42. The buffer water tank 8 serves as a heat energy storage and distribution unit, storing high-temperature hot water continuously heated by the heat pump 6. The stored high-temperature hot water flows to the third piping unit 4 for circulation. When the third water pump 41 starts, it pushes the water in the buffer water tank 8 through the second outlet water pipe 43, the heating unit 44, and the third return water pipe 42, causing the heating unit 44 (such as a floor heating network or radiator assembly) to release heat energy.

[0042] Through the above layout, the three major pipeline units form a compact structure with clear functional zoning on the water receiving pan 2. Combined with the rear protection mechanism of the electrical control box 5, the space utilization and maintenance safety are improved, ensuring the efficient and coordinated operation of the heat pump circulation, domestic water supply and heating system.

[0043] The cleaning agent used above is C3 cleaning agent, model 5709, from CALEFFI, which can remove sludge, scale, and impurities from the water. Alternatively, the cleaning agent can be changed according to actual usage needs, such as replacing it with a bactericide, inhibitor, or leak-proof agent to achieve different maintenance effects on the heat pump circulation system piping.

[0044] See above. Figure 4 , 56. The water softening device 9 includes a tank 91, a stirring device 92, and a dosing device 93. The stirring device 92 is located inside the tank 91. Specifically, the stirring device 92 includes a drive motor 921 located at the top of the tank 91 and a stirring paddle 922 connected to the drive motor 921, with the stirring paddle 922 extending into the tank 91. The tank 91 is provided with a chemical inlet 911, a water inlet pipe 912, and a chemical outlet pipe 913, which are connected to a four-way valve 14. The dosing device 93 includes a chemical tank 931, a dosing pipe 932, and a metering valve 933. The dosing pipe 932 connects the chemical tank 931 to the chemical inlet 911, and the metering valve 933 is located on the dosing pipe 932. The dosing pipe 913 is provided with a second switching valve 914. The chemical tank 931 is used to store cleaning agent, and the metering valve 933 can quantitatively dispense the cleaning agent. When water from the water supply pipe 15 is injected into the tank 91 through the water inlet pipe 912, the metering valve 933 dispenses a quantitative amount of cleaning agent from the medicine compartment 931 into the tank 91 based on the water circulation volume of the first pipeline unit 1 and the third pipeline unit 4. The drive motor 921 synchronously drives the stirring paddle 922 to rotate, so that the cleaning agent and the replenishing water are fully mixed to form a uniform solution. After the second switch valve 914 is opened, the mixed solution is transported to the first return water pipe 13 through the medicine discharge pipe 913, realizing the fully automatic and precise proportioning and dissolution of the cleaning agent during the water replenishment process.

[0045] It should be noted that in actual use, the water softener 9 is an optional component for the user, and its specific structural type can be selected according to the actual use. The water softener 9 is one type of device that can quantitatively add cleaning agent.

[0046] In a preferred embodiment, see [reference] Figure 7 , 8 The water supply pipe 15 is equipped with a backflow preventer 16, and its end is connected to a main pipe 151 and a third branch pipe 152. The main pipe 151 is connected to an external water supply source and is equipped with a first switch valve 153. The housing 71 is equipped with a water inlet 711, and the third branch pipe 152 is connected to the water inlet 711. When the water volume in the first pipeline unit 1 is insufficient, the second switch valve 914 is opened, and the water supply source injects tap water into the main pipe 151. The tap water flows into the water supply pipe 15 through the main pipe 151, thereby replenishing the circulating water in the first pipeline unit 1. When the water level in the tank 71 of the domestic water tank is insufficient, the second switch valve 914 opens, and tap water is injected into the main pipe 151. The tap water flows into the third branch pipe 152 through the main pipe 151, thereby replenishing the domestic water tank 71 with domestic water. By setting up a backflow preventer 16, the backflow of water in the heat pump circulation system pipeline is actively blocked from flowing back into the tank 71 of the domestic water tank 7 through the water replenishment pipe 15 and the third branch pipe 152, thus completely avoiding cross-contamination between circulating water and domestic water and ensuring the safety of domestic water quality.

[0047] In the above, the backflow preventer 16 is a BA type backflow preventer, whose structure is existing technology, and its specific structure and working principle will not be described in detail here.

[0048] It should be noted that, regardless of whether the circulating water in the heat pump circulation system or the domestic water in the tank 71 is being replenished, after the second switch valve 914 is opened, when the four-way valve 14 is open, tap water flows through the main pipe 151 to the water supply pipe 15 to replenish the circulating water. At the same time, the tap water flows through the main pipe 151 to the third branch pipe 152 to replenish the domestic water. Furthermore, under the action of the backflow preventer 16, the circulating water in the heat pump circulation system is prevented from flowing back into the third branch pipe 152 through the water supply pipe 15. When the four-way valve 14 is closed, the tap water only flows through the main pipe 151 to the third branch pipe 152 to replenish the domestic water independently.

[0049] In a preferred embodiment, see [reference] Figure 7 The end of the water supply pipe 15 is connected to a vertically arranged buffer pipe 17, and the two are connected at the top of the buffer pipe 17. The diameter of the buffer pipe 17 is larger than that of the main pipe 151, the third branch pipe 152, and the water supply pipe 15. The lower end of the buffer pipe 17 is connected to the main pipe 151 and the third branch pipe 152 respectively. When the water supply program is started, tap water is injected into the main pipe 151 at high speed. The buffer pipe 17, with the gravity buffer cavity formed by its vertical pipe section and the volume effect generated by the enlarged pipe diameter, actively absorbs the instantaneous flow fluctuations, reducing the water flow velocity entering the water supply pipe 15 by 62%-75%, thereby effectively eliminating the hydraulic shock caused to the heat pump cycle system during the water supply process and avoiding structural damage to the components in the heat pump cycle system.

[0050] In a preferred embodiment, see [reference] Figure 3 , 4 5. The first pipeline unit 1 also includes a heater 18 mounted on the water receiving tray 2. The heater 18 is located below the third pipeline unit 4. The inlet of the heater 18 is connected to the outlet of the heat pump 6 through a first inlet pipe 181. The outlet of the heater 18 is connected to an electric three-way valve 182. The first inlet 721 is connected to the electric three-way valve 182 through a third outlet pipe 183, and the second inlet 81 is connected to the electric three-way valve 182 through a fourth outlet pipe 184. The heater 18 adopts an electric heating mode to perform secondary heating on the water flow that has been initially heated by the heat pump 6, ensuring that the system reaches the preset temperature value. Specifically, the first inlet pipe 181 is equipped with a flow meter to monitor the amount of water entering the heater 18 in real time. The electric three-way valve 182, based on the water usage of the second pipeline unit 3 and the third pipeline unit 4, selectively diverts the secondary heated high-temperature water flow to either the heat exchange component 72 of the domestic water tank 7 or the buffer water tank 8, achieving precise on-demand distribution of heat energy.

[0051] Further, see Figure 3 , 4The third pipeline unit 4 consists of two units. Each of the two third water pumps 41 has a fourth branch pipe 45 at its inlet end, and its outlet end is connected to the inlet end of the corresponding heating unit 44 via a second inlet pipe 46. The two heating units 44 are a floor heating network and a radiator group. Two fourth branch pipes 45 are connected by a mixing three-way valve 47, and a second outlet pipe 43 is connected to one of its fourth branch pipes 45. Specifically, the second outlet pipe 43 is connected to the fourth branch pipe 45 of the third pipeline unit 4 where the radiator group is located. The buffer tank 8 is connected to a fourth return pipe 83. Two third return pipes 42 and the fourth return pipe 83 are arranged side-by-side, and all three are connected at their ends to a mixing pipe 48, which is connected to the mixing three-way valve 47. Based on the temperature difference characteristics of different heating terminals: the floor heating network requires low-temperature water supply, while the radiator group requires high-temperature water supply. When the dual systems are running synchronously, the high-temperature return water from the radiator units is injected into the mixing pipe 48 via the third return pipe 42. After pre-mixing with the high-temperature fresh water output from the buffer tank 8 in the mixing three-way valve 47, a mixed water flow that meets the temperature requirements of underfloor heating is introduced into the corresponding third piping unit 4. Through the cascade utilization of heat energy, the energy waste caused by directly supplying high-temperature water to the underfloor heating is avoided. Furthermore, by recovering waste heat from the high-temperature water of the radiator units, the overall energy efficiency of the system is improved.

[0052] Further, see Figure 3 The two third water pumps 41 are located on both sides of the mixing three-way valve 47, and the second water pump 31 is located in front of the mixing three-way valve 47. Through spatial nesting arrangement, the compactness of the layout of the second pipeline unit 3 and the two third pipeline units 4 is further improved, so that the overall layout shortens the overall length compared with the traditional side-by-side layout.

[0053] In a preferred embodiment, see [reference] Figure 2 , 3 The magnetic mud filter 11 and the first water pump 12 are arranged sequentially away from the electrical control box 5. The first return water pipe 13 is located above the magnetic mud filter 11. The four-way valve 14 is located near the electrical control box 5. The water supply pipe 15 extends to the front of the electrical control box 5, and the backflow preventer 16 is located near the first water pump 12. This arrangement allows the first pipeline unit 1, the second pipeline unit 3, and the third pipeline unit 4 to be arranged side by side. Since the first pipeline unit 1 is a heat pump circulation system (focused on the preparation of high-temperature circulating water), and the second pipeline unit 3 and the third pipeline unit 4 belong to the water / heating circulation system (performing heat exchange, transportation, and distribution), the parallel layout of the three functional areas achieves physical separation between the high-temperature water preparation pipeline and the heat exchange unit pipeline, avoiding the cross-setting of the three system pipelines and making assembly and maintenance more efficient.

[0054] In a preferred embodiment, see [reference] Figure 2 , 3The system also includes a first support bar 10 and a second support bar 20, which are arranged sequentially from bottom to top on the side of the water receiving tray 2 away from the electrical control box 5. The inlet ends of the main pipe 151, the third branch pipe 152, the first inlet pipe 181, the third outlet pipe 183, the fourth outlet pipe 184, and the second return pipe 32 are fixed to the water receiving tray 2. The first branch pipe 131, the second branch pipe 132, the first outlet pipe 33, the two third return pipes 42, and the fourth return pipe 83 are fixed to the first support bar 10. The outlet ends of the second outlet pipe 43, the two second inlet pipes 46, and the second return pipe 32 are fixed to the second support bar 20. Through the water receiving tray 2, the first support bar 10, and the second support bar 20, pipes of different heights are installed in layers, which facilitates the installation of each pipe and effectively improves the installation stability. All pipe openings face away from the electrical control box 5, forming an unobstructed operating interface and improving the efficiency of external pipe connections; and the pipe connection work area is far away from the electrical control box 5, ensuring the waterproof performance of the electrical control box 5.

[0055] In summary, this utility model uses a water receiving tray 2 to collect condensate, above which are arranged three functional piping units: the first piping unit 1 (heat pump circulation system), the second piping unit 3 (domestic water circulation system), and the third piping unit 4 (heating water circulation system). Each unit has an independent electrical control box 5 at its rear, forming a physically isolated layout structure of "piping at the front, electrical control at the rear." This partitioned, parallel layout eliminates the tangling of pipes, creating a highly integrated three-dimensional structure that effectively improves space utilization and maintenance safety. The first piping unit 1 integrates a magnetic mud filter 11, a first water pump 12, and a water supply pipe 15 with a four-way valve 14. The four-way valve 14 switches between automatic cleaning and circulating water supply modes, and the water supply pipe 15 is equipped with a backflow preventer 16 to effectively prevent circulating water from flowing back and contaminating the domestic water supply. The dual third pipeline unit 4 is connected by a mixing three-way valve 47 and a mixing pipe 48 to realize the tiered utilization of heat between heating units 44 with temperature differences. By utilizing the waste heat recovery of high-temperature water, the overall energy efficiency of the system is effectively improved.
