Description

Technical Field

[0001] This utility model relates to the field of heat pump components, specifically a geothermal source heat pump installation component. Background Technology

[0002] A geothermal heat pump system extracts relatively high-temperature groundwater into a heat pump circulation network. The circulation network passes through a water tank filled with water. Utilizing the temperature difference between the inside and outside of the heat pump network, the groundwater in the network heats the cold water in the tank for use at indoor water points. After heat exchange, the groundwater returns to the ground or to a pre-buried storage tank near the underground geothermal source via the heat pump network.

[0003] As one of the components in a geothermal heat pump installation, the heat exchange layout inside the water tank typically involves twisting the heat pump pipe network into a spiral shape to increase the contact area between water bodies of different temperatures inside and outside the pipe. Although the spiral coil expands the heat conduction area, this static layout inevitably results in the water body near the pipe wall being at a higher temperature, while the water body further away from the pipe body takes a relatively long time to obtain sufficient heat. This leads to the problem that obtaining hot water and heat from the heat pump always requires a certain amount of time. If the heat source water circulation inside the heat pump continues, although it can keep the water in the tank at a relatively high constant temperature, the continuous operation of the heat pump means that indoor water use occurs indirectly, leading to unnecessary energy waste and violating the original intention of saving energy by utilizing geothermal energy.

[0004] Therefore, a geothermal source heat pump installation component is provided. Utility Model Content

[0005] I. Technical problems to be solved

[0006] The technical problem this utility model aims to solve is that in geothermal heat pump systems, continuous water supply, coupled with indirect water and heat use, can lead to energy waste. Furthermore, when heating begins before water use, the water in the tank heats up relatively slowly, and the water temperature may be uneven when needed, causing the water flowing from the indoor outlet pipe to fluctuate in temperature.

[0007] II. Technical Solution

[0008] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a geothermal heat pump installation component, including a hot water tank, a heat pump water supply pipe installed above the hot water tank, an indoor water supply pipe connected to the top of the hot water tank, and a heat pump return water pipe and an indoor water supply pipe respectively connected to the bottom two sides of the hot water tank.

[0009] The hot water tank is rotatably connected to a heat exchange tube assembly whose upper and lower ends are respectively connected to the heat pump water supply pipe and the heat pump water return pipe. The heat exchange tube assembly contains multiple thin-walled and slender heat-conducting tubes. A drive assembly for driving the heat exchange tube assembly to rotate is installed above the hot water tank.

[0010] A circulation pipe is installed on one side of the hot water tank, with its upper and lower ends respectively connected to the top and bottom of the hot water tank. A circulation pump is installed on the circulation pipe.

[0011] Furthermore, the drive assembly includes a drive shaft rotatably mounted above the hot water tank, a motor that drives and cooperates with the drive shaft is mounted on the top of the hot water tank, a worm gear is connected to the drive shaft, and a worm wheel that cooperates with the worm gear is connected to the top of the heat exchange tube assembly extending outside the hot water tank.

[0012] Furthermore, the heat exchange tube assembly also includes connecting pipes located at the top and bottom, having a tee pipe and a reducing pipe structure, with the worm gear connected to the connecting pipe located at the top.

[0013] Furthermore, the ends of the connecting pipes are respectively connected to the bottom end of the heat pump water supply pipe and the top end of the heat pump water return pipe via sealed rotary joints.

[0014] Furthermore, the indoor water supply pipe is connected to the circulation pipe, and an output pump is installed on the indoor water supply pipe.

[0015] III. Beneficial Effects

[0016] The advantages of this utility model compared with the prior art are as follows: the water tank assembly in the geothermal heat pump system, by setting a water stirring mechanism and a circulation mechanism inside the tank, promotes the internal circulation of water in the tank, and ensures that the water comes into uniform and sufficient contact with the heat exchange tube, thereby improving the heating speed and the degree of heat absorption, so as to quickly obtain hot water and heat at a sufficient temperature.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0024] Example 1

[0025] A geothermal heat pump installation assembly, combined with an attached Figure 1-2 It includes a hot water tank 1, a heat pump water supply pipe 3 installed above the hot water tank 1, an indoor water supply pipe 2 connected to the top of the hot water tank 1, and a heat pump return pipe 6 and an indoor water supply pipe 9 respectively connected to the bottom two sides of the hot water tank 1.

[0026] Hot water tank 1 is a component of the geothermal heat pump assembly. Its main function is to use the groundwater extracted by the heat pump to extend into the hot water tank 1 through the circulation system composed of the heat pump supply pipe 3 and the heat pump return pipe 6, exchange heat with the water stored in the hot water tank 1, thereby heating the water in the hot water tank 1, and then transporting it to the indoor water point through the indoor water supply pipe 9.

[0027] Combined with appendix Figure 3 The hot water tank 1 is rotatably connected to a heat exchange tube group 5, which is connected to the heat pump water supply pipe 3 and the heat pump water return pipe 6 at its upper and lower ends respectively. The heat exchange tube group 5 contains a number of thin-walled and slender heat-conducting tubes.

[0028] The heat exchange section of the tube is divided into multiple thin tubes, which can accelerate the heat transfer between the water inside and outside the tube.

[0029] Furthermore, multiple heat exchange tubes are neatly arranged in a row, forming a shape similar to a stirring plate inside the hot water tank 1. When the heat exchange tube assembly 5 rotates inside the hot water tank 1, it will cause the water flow inside the hot water tank 1 to rotate, further improving the efficiency of water temperature balance inside and outside the tubes, allowing the water inside the hot water tank 1 to heat up quickly. If it is summer, this method is also feasible to obtain cold water using a geothermal heat pump system.

[0030] Combined with appendix Figure 4A drive assembly for driving the heat exchange tube assembly 5 to rotate is installed above the hot water tank 1. The drive assembly includes a drive shaft 11 rotatably installed above the hot water tank 1. A motor 12 that drives and cooperates with the drive shaft 11 is installed on the top of the hot water tank 1. A worm gear 13 is connected to the drive shaft 11. The top of the heat exchange tube assembly 5 extends to the outside of the hot water tank 1 and is connected to a worm wheel 14 that cooperates with the worm gear 13.

[0031] After the motor 12 starts running, it drives the transmission shaft 11 to rotate. Under the mutual transmission and cooperation of the worm gear 14 and the worm 13, the heat exchange tube group 5 rotates in the hot water tank 1, stirring the water stored in the hot water tank 1 and making it churn, thus increasing the degree of heat transfer.

[0032] Combined with appendix Figure 3 The heat exchange tube assembly 5 also includes connecting pipes 4 located at the top and bottom, which have a three-way pipe and a reducing pipe structure. The worm gear 14 is connected to the connecting pipe 4 located at the top. The ends of the connecting pipe 4 are respectively connected to the bottom end of the heat pump water supply pipe 3 and the top end of the heat pump water return pipe 6 through sealed rotary joints.

[0033] Example 2

[0034] Combined with appendix Figure 1 and attached Figure 3 The hot water tank 1 is provided with a circulation pipe 7 installed on one side, with the upper and lower ends respectively connected to the top and bottom of the hot water tank 1. A circulation pump 8 is installed on the circulation pipe 7. An indoor water supply pipe 9 is connected to the circulation pipe 7 and an output pump 10 is installed on the indoor water supply pipe 9.

[0035] The plate-type heat exchange tube assembly 5 used for stirring the water in the hot water tank 1 is arranged as high as possible inside the hot water tank 1, and a circulation pipe 7 is connected to the bottom. The end of the circulation pipe 7 is connected to the top of the hot water tank 1. This can transport the cold water at the bottom that is far away from the heat exchange area to the top, and can also effectively break the stratification phenomenon caused by the horizontal rotation and stirring of the heat exchange tube assembly 5 in the water. This promotes increased connection and full integration of different areas in the water, making the water temperature relatively uniform, and can also further accelerate the efficiency of heat transfer.

[0036] The indoor output pipe is installed on the circulation pipe 7, forming two branches together with the latter half of the circulation pipe 7. On each branch, a circulation pump 8 and an output pump 10 are installed respectively. When heating water, the circulation pump 8 is turned on and the output pump 10 is turned off. When the water temperature reaches a suitable level, hot water is delivered to the indoor water point. At this time, the circulation pump 8 is turned off and the output pump 10 is turned on.

[0037] In practical implementation, the hot water tank 1, as one of the heat pump components, operates by drawing hot water from underground into a pipe network system consisting of the heat pump supply pipe 3, the heat exchange pipe assembly 5, and the heat pump return pipe 6. The hot water in the pipes exchanges heat with the cooler water in the hot water tank 1, thus raising the temperature of the water in the tank. Simultaneously, the heat exchange pipe assembly 5, which is shaped like a plate frame, continuously rotates within the hot water tank 1 under the operation of the motor 12, agitating the water and promoting relatively sufficient heat exchange. Furthermore, the circulation pipe 7, equipped with a circulation pump 8 on one side of the hot water tank 1, continuously pumps water from the bottom to the top, further improving the heating efficiency and thoroughness of the water. Soon, the water in the hot water tank 1 reaches a sufficient temperature, at which point all the aforementioned mechanisms can stop operating, and the output pump 10 can be turned on to deliver the hot water from the tank 1 to the corresponding water point indoors for use.

[0038] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
