Description

Technical Field

[0001] This application relates to the field of water source heat pumps, and more particularly to a water source heat pump preparation system. Background Technology

[0002] In conventional project design, boilers are used to produce domestic hot water and heating hot water, while chiller units produce chilled water; the chilled water system and the hot water system are essentially unrelated. Later, for energy-saving considerations, heat recovery systems or water source heat pump systems are added to the design to address the recycling of energy within the building. However, in many projects where water source heat pump systems for producing hot water are designed, these devices are rarely operational in practice.

[0003] A water source heat pump unit uses chilled water on the evaporator side and hot water production on the condenser side. For this heat pump unit to operate normally, the balance of heating and cooling supply on both sides must be considered. Because the building's chilled water load curve does not match its hot water load curve, the water source heat pump system cannot function properly if these demands are not matched. Generally, chilled water systems are designed by HVAC professionals, while hot water systems are designed by plumbing or power professionals. This issue of heating and cooling balance is rarely considered, so it's understandable that water source heat pump systems may malfunction.

[0004] However, when a water source heat pump is working, the pumped water needs to be filtered to remove impurities, thus ensuring the lifespan and performance of the heat pump. Current filtration methods typically involve installing a filter screen inside the pipe to remove impurities. However, after a period of use, the filter screen is prone to clogging, requiring the heat pump to be stopped and the filter replaced, which can affect the heat pump's efficiency. Utility Model Content

[0005] To address the issue that filter screens tend to become clogged after a period of use, necessitating the shutdown of the water source heat pump and replacement of the filter, which in turn affects the pump's efficiency, this application provides a water source heat pump preparation system.

[0006] The water source heat pump preparation system provided in this application adopts the following technical solution: it includes a heat pump body, an inlet pipe fixed on one side of the heat pump body, a first tee pipe fixed at one end of the inlet pipe, control valves provided on both sides of the middle of the first tee pipe, corrugated pipes detachably connected to both ends of the first tee pipe, two corrugated pipes detachably connected to both ends of a second tee pipe, connecting rings fixed at both ends of the two corrugated pipes, and second limiting rings fixed near the inner wall of one end of each of the four connecting rings, with filter screens detachably connected to one side of each of the four second limiting rings.

[0007] By adopting the above technical solution, the water flow entering the heat pump body is diverted by using a first three-way pipe, two corrugated pipes, and a second three-way pipe. The water flow is selected by controlling two control valves to select the corresponding pipes. The corrugated pipe and filter screen to be used are selected. When it is necessary to replace the filter screen inside the corrugated pipe, the flow control valve is closed and the closed control valve is opened to perform the subsequent disassembly and assembly of the corrugated pipe and filter screen.

[0008] Preferably, a filter hole is provided through one side of the filter screen, and multiple filter holes are provided. The multiple filter holes are arranged in a filling and equidistant manner, and the width of the filter hole in the filter screen near the heat pump body is smaller than the width of the filter hole in the other filter screen.

[0009] By adopting the above technical solution, the filter screen that first comes into contact with the water flow uses large filter holes for initial filtration, and then uses small filter holes for secondary filtration, making the water flow filtration more thorough.

[0010] Preferably, the outer wall of the connecting ring is rotatably connected to a threaded connecting sleeve, the inner wall of the threaded connecting sleeve is provided with an internal thread, and the outer walls of both ends of the first tee pipe and both ends of the second tee pipe are provided with external threads, the external threads being used in conjunction with the internal threads.

[0011] By adopting the above technical solution, the installation and disassembly of the corrugated pipe can be completed by simply disassembling and installing the threaded connecting sleeve with the first tee pipe and the second tee pipe.

[0012] Preferably, a sealing ring is fixed at the end of each of the four connecting rings away from the bellows, and the four sealing rings are respectively connected to the two ends of the first tee pipe and the two ends of the second tee pipe.

[0013] By adopting the above technical solution, after the corrugated pipe is connected, the sealing ring is squeezed to fill the gap between the connecting ring and the first tee pipe and the second tee pipe, thus preventing water leakage.

[0014] Preferably, the second limiting ring is rotatably connected to a threaded rod on the side away from the bellows, and the outer wall of the threaded rod is threadedly connected to a first limiting ring. The first limiting ring and the second limiting ring are used in combination.

[0015] By adopting the above technical solution, the position of the first limiting ring is controlled by rotating the threaded rod, so that the first limiting ring presses the filter screen onto the second limiting ring, thereby limiting the filter screen. This makes the filter screen easy to install and remove, and allows for individual replacement when needed, thus saving resources.

[0016] Preferably, the second three-way pipe is provided in multiple ways, and the multiple threaded rods are arranged in a circumferentially equidistant manner, with a cross groove opened on one side of each threaded rod.

[0017] By adopting the above technical solution, the position of the first limiting ring can be adjusted by inserting a screwdriver into the cross groove and rotating the threaded rod.

[0018] Preferably, a flow monitor is fixed through the top of the water inlet pipe, and the bottom of the flow monitor is located in the middle of the water inlet pipe.

[0019] By adopting the above technical solution, the water flow inside the inlet pipe can be monitored by a flow monitor. When the water flow is low, the corrugated pipe and filter screen for filtering water can be switched.

[0020] In summary, this application includes at least the following beneficial technical effects:

[0021] 1. This application monitors the water flow inside the inlet pipe using a flow monitor. When the water flow is low, the flow control valve is closed and the closed control valve is opened to allow for the subsequent disassembly and assembly of the corrugated pipe and filter screen. During filtration, the filter screen that first comes into contact with the water flow uses a large filter hole for initial filtration, and then uses a small filter hole for secondary filtration, making the water flow filtration more thorough. This achieves the effect of double filtration of the water entering the water source heat pump, and replacing the filter device does not affect the operation of the water source heat pump.

[0022] 2. This application allows for easy removal of the old filter screen by disassembling the threaded connecting sleeve from the first tee pipe and the second tee pipe. A screwdriver inserted into the Phillips head groove and the threaded rod rotated can adjust the position of the first limiting ring, allowing the old filter screen to be removed and the new filter screen installed. By adjusting the position of the first limiting ring, the first limiting ring presses the filter screen against the second limiting ring, thus limiting the filter screen's position. This makes filter screen removal and installation convenient, and allows for individual replacement of the filter screen 12 when needed, saving resources and achieving the effect of quick replacement while reducing replacement costs.

Detailed Implementation

[0028] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0029] This application discloses a water source heat pump preparation system, including a heat pump body 1. A water inlet pipe 2 is fixed to one side of the heat pump body 1. A first three-way pipe 3 is fixed to one end of the water inlet pipe 2. Control valves 6 are provided on both sides of the middle of the first three-way pipe 3. Corrugated pipes 7 are detachably connected to both ends of the first three-way pipe 3. One end of each of the two corrugated pipes 7 is detachably connected to both ends of the second three-way pipe 4. Connecting rings 8 are fixed to both ends of the two corrugated pipes 7. Second limiting rings 13 are fixed to the inner wall of each of the four connecting rings 8 near the end of the corrugated pipes 7. Filter screens 12 are detachably connected to one side of each of the four second limiting rings 13. The water flow entering the heat pump body 1 is diverted by using the first three-way pipe 3, the two corrugated pipes 7, and the second three-way pipe 4. The water flow is selected through the corresponding pipe by controlling the two control valves 6. The corrugated pipes 7 and filter screens 12 to be used are selected. When it is necessary to replace the filter screen 12 inside the corrugated pipe 7, the flow control valve 6 is closed and the closed control valve 6 is opened to allow for subsequent disassembly and assembly of the corrugated pipes 7 and filter screens 12.

[0030] Reference Appendix Figure 3 The filter screen 12 has a filter hole 121 through one side. There are multiple filter holes 121, which are arranged in a filling and equidistant manner. The width of the filter hole 121 in the filter screen 12 near the heat pump body 1 is smaller than the width of the filter hole 121 in the other filter screen 12. During filtration, the filter screen 12 that first comes into contact with the water flow uses the larger filter hole 121 for initial filtration, and then uses the smaller filter hole 121 for secondary filtration, so that the water flow filtration is more thorough.

[0031] Reference Appendix Figure 2 The outer wall of the connecting ring 8 is rotatably connected to a threaded connecting sleeve 9. The inner wall of the threaded connecting sleeve 9 is provided with an internal thread 91. The outer walls of both ends of the first tee pipe 3 and both ends of the second tee pipe 4 are provided with external threads. The external threads are used in conjunction with the internal threads 91. When installing and disassembling the bellows 7, the threaded connecting sleeve 9 can be disassembled and installed with the first tee pipe 3 and the second tee pipe 4.

[0032] Reference Appendix Figure 3Each of the four connecting rings 8 has a sealing ring 10 fixed at the end away from the corrugated pipe 7. The four sealing rings 10 are respectively connected to the two ends of the first tee pipe 3 and the two ends of the second tee pipe 4. After the corrugated pipe 7 is connected, the sealing rings 10 are squeezed and fill the gap between the connecting rings 8 and the first tee pipe 3 and the second tee pipe 4 to prevent water leakage.

[0033] Reference Appendix Figure 3 and 4 The second limiting ring 13 is rotatably connected to a threaded rod 14 on the side away from the bellows 7. The outer wall of the threaded rod 14 is threadedly connected to a first limiting ring 11. The first limiting ring 11 and the second limiting ring 13 are used together. By rotating the threaded rod 14, the position of the first limiting ring 11 is adjusted, so that the first limiting ring 11 presses the filter screen 12 onto the second limiting ring 13, thereby limiting the filter screen 12. This makes it easy to install and remove the filter screen 12. When it needs to be replaced later, the filter screen 12 can be replaced separately, which saves more resources.

[0034] Reference Appendix Figure 3 and 4 The second three-way pipe 4 is provided with multiple threaded rods 14 arranged in a circumferentially equidistant pattern. A cross groove 141 is provided on one side of the threaded rod 14. By inserting a screwdriver into the cross groove 141 and rotating the threaded rod 14, the position of the first limiting ring 11 can be adjusted.

[0035] Reference Appendix Figure 1 The top of the inlet pipe 2 is fixed with a flow monitor 5, and the bottom of the flow monitor 5 is located in the middle of the inlet pipe 2. The flow monitor 5 monitors the water flow inside the inlet pipe 2. When the water flow is small, the corrugated pipe 7 and the filter screen 12 for filtering water can be switched.

[0036] The implementation principle of a water source heat pump preparation system according to an embodiment of this application is as follows: First, the second three-way pipe 4 is connected to an external underground water source. Water is introduced from the corrugated pipe 7 into the first three-way pipe 3, and then from the inlet pipe 2 into the heat pump body 1. During use, the water flow rate inside the inlet pipe 2 is monitored by the flow monitor 5. When the water flow is small, the flow control valve 6 is closed and the closed control valve 6 is opened to allow for subsequent disassembly and assembly of the corrugated pipe 7 and the filter screen 12. At this time, the filter screen 12 is replaced without affecting the normal operation of the heat pump body 1. Both ends of the first three-way pipe 3 and both ends of the second three-way pipe 4 are provided with external threads on their outer walls. The external threads are used in conjunction with the internal threads 91. Subsequently, when disassembling the corrugated pipe 7, the threaded connecting sleeve 9 is disconnected from the first three-way pipe 3 and the second three-way pipe 4. Insert a screwdriver into the Phillips head groove 141 and rotate the threaded rod 14 to adjust the position of the first limiting ring 11. Remove the old filter screen 12 and install the new filter screen 12. By rotating the threaded rod 14, the position of the first limiting ring 11 is adjusted so that the first limiting ring 11 presses the filter screen 12 onto the second limiting ring 13, thus limiting the filter screen 12. This makes it easy to install and remove the filter screen 12. When it needs to be replaced later, the filter screen 12 can be replaced separately, which saves resources. After the new filter screen 12 is installed, install the corrugated pipe 7 and connect the threaded connecting sleeve 9 to the first tee pipe 3 and the second tee pipe 4. The sealing ring 10 is compressed and fills the gap between the connecting ring 8 and the first tee pipe 3 and the second tee pipe 4 to prevent water leakage.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
