Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat pump technology, and in particular to an energy storage ground source heat pump unit. Background Technology
[0002] Ground source heat pump units utilize the relatively constant temperature of underground soil as a heat source and cold source. In winter, they extract heat from the soil to heat buildings, and in summer, they release heat into the soil to cool buildings. By adding an energy storage device to the system, the heat pump is turned on to store energy during off-peak electricity hours or when cooling / heating demand is low. During peak electricity hours or when cooling / heating demand is high, the energy stored in the energy storage device is used first, reducing or even shutting down the operation of the heat pump unit.
[0003] A Chinese patent (publication number: CN223165620U) discloses a ground source heat pump unit with a heat exchange structure. During the heat exchange process, multiple protrusions on the outside of the heat exchange rack form a wave-shaped structure, which increases the contact area between the outside of the heat exchange rack and the soil, thereby improving the heat exchange efficiency of the heat exchange rack. At the same time, the heat exchange rack is designed as a wave-shaped structure, which further improves the heat exchange efficiency of the heat exchange rack by increasing the overall contact area between the heat exchange rack and the soil. However, when the above-mentioned patent is used, the heat exchanger is made into a wave shape and a large number of protrusions are welded. Numerous baffles and U-shaped connecting pipes are also installed inside. The process is overly complicated and the production cost is high. The key point is that in the invisible and unmaintainable environment of underground burial, the complex structure and welding points make the patented technology have a higher risk of failure in actual application.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] like Figures 1 to 4 As shown, this utility model provides a technical solution: a ground source heat pump unit with energy storage, comprising: Mounting bracket 1; The water supply assembly 2 includes a water collection tank 21 and a water distribution tank 28 connected to the top and bottom of the mounting bracket 1, respectively. A heat exchange assembly 3 is connected between the water collection tank 21 and the water distribution tank 28. The heat exchange assembly 3 includes at least one vertically arranged vertical pipe 34. A heat-conducting extension structure for increasing the heat exchange area is fixedly connected to the outside of the vertical pipe 34. Side water pumps 24 are installed on both sides of the mounting bracket 1. The end of the side water pump 24 away from the mounting bracket 1 is fixedly connected to a threaded water pipe 23 through a bottom pipe 26 and a horizontal pipe 27. A side water tank 22 is fixedly connected to the outer wall of the horizontal pipe 27. A first installation valve 25 and a second installation valve 4 are respectively installed at the top of the side water tank 22 and the top of the water collection tank 21.
[0025] like Figures 1 to 5 As shown, this utility model employs a modular, vertical corrugated pipe, a series heat-conducting plate 35, and a side-mounted threaded water pipe 23 in a split structure. During use, the mounting bracket 1 and the side water tank 22 are placed underground. Workers connect the inlet pipe 33 via the first mounting valve 25 and the outlet pipe via the second mounting valve 4. When the system is running, the water collection tank 21 stores water, and the inlet pump 32 mounted on the mounting bracket 1 is activated to pump water through the inlet pipe 33 into the vertical pipe 34. At this time, the side water pump 24 is not activated, allowing the heat-conducting plate 35 and the series plate 31 to fully conduct heat to the soil. The heat exchanger heats or releases heat from the water in the vertical pipe 34. When the water temperature in the vertical pipe 34 reaches the set value, the side water pump 24 is activated to pump the water into the threaded water pipe 23 in the side water tank 22. The threaded design extends the heat exchange path, achieving efficient secondary heat exchange. Finally, the water flows out through the second installation valve 4. The standardized components replace the complex internal flow channels and irregular welding, which greatly reduces production costs and flow resistance energy consumption. Through the staged heat exchange operation mode, while ensuring efficient heat exchange, the system's long-term stability and anti-clogging ability in non-maintainable environments are improved.
[0026] like Figures 2 to 4 As shown, the heat exchange assembly 3 includes an inlet pipe 33 fixedly connected to the bottom of the water collection tank 21. An inlet pump 32 is fixedly connected to one end of the inlet pipe 33 away from the water collection tank 21. In use, the inlet pipe 33 facilitates the inlet pump 32 to pump the water stored in the water collection tank 21 to the vertical pipe 34, where the vertical pipe 34 absorbs and releases heat. The water collection tank 21 and the water distribution tank 28 are both fixed to the mounting bracket 1 by bolts.
[0027] like Figures 2 to 5As shown, the water inlet pump 32 is fixedly connected inside the mounting bracket 1. The end of the water inlet pump 32 away from the water inlet pipe 33 is fixedly connected to the top of the vertical pipe 34, and the bottom of the vertical pipe 34 is fixedly connected to the top of the water distribution tank 28. In use, by setting the water inlet pump 32 to be fixedly connected inside the mounting bracket 1, and the vertical pipe 34 being a corrugated stainless steel pipe, heat from the soil is conducted through a series of heat-conducting plates 31 and heat-conducting plates 35, achieving the effect of heat collection and release.
[0028] like Figure 5 As shown, a series plate 31 is fixedly connected to the outer wall of the vertical pipe 34. In use, the series plate 31, which is made of metal and is used for heat conduction, is placed in the middle position, and the outer wall of the series plate 31 directly contacts the soil.
[0029] like Figures 1 to 3 As shown, heat-conducting plates 35 are fixedly connected to both sides of the mounting bracket 1. The inner walls of the heat-conducting plates 35 are fixedly connected to the series plates 31 on both sides. The series plates 31 of the same material are welded and fixed to the heat-conducting plates 35 to facilitate heat conduction.
[0030] like Figures 3 to 5 As shown, the bottom pipe 26 is fixedly connected to the horizontal pipe 27. When in use, the bottom pipe 26 is fixedly connected to the horizontal pipe 27. The bottom pipe 26 and the water pump are fixed on both sides of the mounting bracket 1. Both ends of the water pump are connected to the bottom pipe 26. The part of the bottom pipe 26 placed inside the mounting bracket is fixedly connected to the vertical pipe 34.
[0031] In this utility model, the series plate 31, the heat-conducting plate 35, and the side water tank 22 are all made of aluminum alloy.
[0032] Working principle: like Figure 1-5 As shown, during use, the mounting bracket 1 and the side water tank 22 are placed underground. Before burying, the workers use bolts to connect the inlet pipe through the first mounting valve 25 and bolts to connect the outlet pipe through the second mounting valve 4. Water is stored in the water collection tank 21. The water inlet pump 32 installed on the mounting bracket 1 is started. The water inlet pump 32 pumps water into the vertical pipe 34 through the water inlet pipe 33. At this time, the side water pump 24 is not started, so that the heat conduction plate 35 and the series plate 31 can conduct heat fully, and the water in the vertical pipe 34 is heated or released. When the water temperature in the vertical pipe 34 increases, the side water pump 24 is started, which pumps water into the threaded water pipe 23. The side water tank 22 also uses heat-conducting material, and the threaded water pipe 23 arranged in the side water tank 22 can better achieve heat exchange. At this time, the second installation valve 4 is opened, so that the water is pumped out by the side water pump 24 and flows out from the second installation valve 4.
[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
