Description

Technical Field

[0001] The present invention relates to the technical field of ground source heat pump equipment, and in particular to an energy-saving ground source heat pump air-conditioning device capable of compensating for shallow ground heat in summer. Background Art

[0002] A ground-source heat pump air conditioner is an air conditioner that uses heat exchange from shallow underground geothermal energy for heating and cooling. In some cold regions, the long-term, large-scale heat extraction from traditional geothermal air conditioners in winter can lead to insufficient heat storage in the soil, causing the soil temperature to drop year by year, thus affecting winter heating efficiency.

[0003] Existing ground source heat pump air conditioning devices use U-shaped buried pipes that penetrate deep into the ground to exchange heat and cold. During the installation process, the buried pipes will rub against the soil, rocks and other media underground, and the buried pipes will wear due to friction. The wear of the buried pipes is more likely to cause leakage during long-term use, which increases the maintenance burden of the buried pipes in the later stage. In addition, the U-shaped buried pipes are arranged side by side, resulting in the U-shaped buried pipes being close to each other and easily exchanging heat with each other, which reduces the heat exchange efficiency. Summary of the Invention

[0004] The present invention provides an energy-saving ground source heat pump air-conditioning device which can compensate for shallow geothermal heat in summer, wherein the connecting pipe and the underground heat exchange pipe are tightly fitted to the outside of the underground pipe rack, and the compact structural design effectively reduces the diameter of the overall device, reduces the probability of friction and wear between the underground heat exchange pipe and external soil, rock and other media during installation, and reduces the leakage of the underground heat exchange pipe due to wear. The outer support rod supports the connecting pipe and the underground heat exchange pipe to move outward, and in the process of the underground heat exchange pipe expanding outward, the distance between the underground heat exchange pipes is effectively expanded, thereby expanding the influence range of heat exchange of the underground heat exchange pipe and the expansion of the heat exchange range.

[0005] The present invention provides an energy-saving ground source heat pump air-conditioning device which can compensate for shallow geothermal heat in summer. The device specifically comprises an underground pipe rack, an upper auxiliary fixing frame, a heat pump module and a buffer water tank module. The upper part of the underground pipe rack is rotatably connected to the center circle of the upper auxiliary fixing frame. The heat pump module and the buffer water tank module are arranged above the underground pipe rack. The lower part of the underground pipe rack is rotatably provided with an upper connecting rotating frame. The outer annular array of the upper connecting rotating frame is provided with a rotatable outer support rod. The outer support rod and the middle connecting pipe are rotatably connected through a rotating shaft. The lower part of the underground pipe rack is threadedly connected to the lower threaded rod. The lower part of the lower threaded rod is fixedly connected to the lower connecting fixing frame. The lower end of the lower threaded rod is fixedly connected to the lower conical base. The inner side of the middle connecting pipe is penetrated by an underground heat exchange pipe.

[0006] Furthermore, the lower rotating shaft of the middle connecting pipe is rotatably connected to another outer support rod, and the tail end of the outer support rod at the lower part of the middle connecting pipe is rotatably connected to the lower connecting fixing frame through the rotating shaft. When the buried pipe rack and the lower threaded rod move closer, the middle connecting pipe moves away from the buried pipe rack. After the buried heat exchange pipe expands outward, the distance between the buried heat exchange pipes is further increased.

[0007] Furthermore, the underground heat exchange pipe is a U-structure, and the two ends of the underground heat exchange pipe respectively pass through the middle connecting pipes on both sides of the buried pipe rack. The lower conical base is a conical structure that is wide at the top and narrow at the bottom. The underground heat exchange pipe and the middle connecting pipe are both above the lower conical base, and the lower conical base enters the ground first.

[0008] Furthermore, a through hole is opened in the middle annular array of the upper auxiliary fixing frame, an inner guide rotating frame is rotatably provided on the inner side of the through hole, the upper and lower parts of the inner guide rotating frame are slidably connected to the side movable slide, the inner side of the side movable slide is rotatably connected to the inner pulley, and the upper and lower parts of the inner guide rotating frame are rotatably provided with an external threaded rod.

[0009] Furthermore, the upper and lower parts of the upper auxiliary fixing frame are rotatably provided with inner pulleys, the inner pulleys of the upper auxiliary fixing frame and the inner pulleys of the side movable slide are oppositely arranged, the buried heat exchange pipe is located between the inner pulleys of the upper auxiliary fixing frame and the side movable slide, the external threaded rod and the side movable slide are threadedly connected, the side movable slide moves with the external threaded rod, the spacing between the inner pulleys of the side movable slide and the upper auxiliary fixing frame is adjusted, and the distance between the inner pulleys of the side movable slide and the upper auxiliary fixing frame is adjusted.

[0010] Furthermore, the heat pump module is connected to two lower heat exchangers, and a distribution box is fixedly installed above the lower heat exchangers. One of the lower heat exchangers is provided with a water outlet port and a return water port. The water outlet port and the return water port are connected to the water outlet pipe and the return water pipe through a control valve body, and the return water pipe is connected to a circulating pump.

[0011] Furthermore, the buffer water tank module is connected to the solar panel pipeline, and the upper and lower connecting ports of the buffer water tank module are connected to the outlet pipe and the return pipe through the control valve body respectively. The buffer water tank module connects the outlet pipe, the return pipe and the buried heat exchange pipe through the hot water continuously generated by the solar panel.

[0012] Furthermore, the distribution box and the heat pump module, the control valve body, and the circulating pump are electrically connected and controlled, and the head and tail ends of the buried heat exchange pipe are respectively connected to the outlet pipe and the return pipe. The circulating pump drives the water in the buried pipe rack to flow through the underground through the outlet pipe and the return pipe and finally return to the lower heat exchanger.

[0013] The present invention provides an energy-saving ground source heat pump air conditioning device capable of compensating for shallow ground heat in summer, which has the following beneficial effects:

[0014] During the installation of the buried pipe rack deep underground, the middle connecting pipe and the buried heat exchange pipe fit tightly to the outside of the buried pipe rack. The compact structural design effectively reduces the diameter of the entire device, reduces the probability of friction and wear between the buried heat exchange pipe and external soil, rock and other media during the installation process, reduces the leakage of the buried heat exchange pipe due to wear, and significantly improves the safety and reliability of the buried heat exchange pipe.

[0015] After the buried pipe rack moves to the specified depth, the outer support rods support the middle connecting pipe and the buried heat exchange pipe to move outward. In the process of outward expansion of the buried heat exchange pipe, the distance between the buried heat exchange pipes is effectively expanded. Compared with the initial compact state, the influence range of the heat exchange of the buried heat exchange pipe is expanded. The expansion of the heat exchange range means that the heat exchange area between the buried pipe and the surrounding soil is increased, and the heat exchange efficiency is improved.

[0016] When the underground heat exchange tube expands outward, the underground heat exchange tube moves outward along the inner pulley and bends. The inner pulley rotates synchronously with the movement of the underground heat exchange tube, reducing the friction resistance of the underground heat exchange tube during movement. The inner pulley controls the bending amplitude of the underground heat exchange tube to avoid the situation where the underground heat exchange tube bends too much and causes poor water flow, thereby ensuring the normal circulation of the fluid in the underground heat exchange tube. According to the underground heat exchange tubes with different diameters, the side moving slide moves with the external threaded rod, thereby flexibly adjusting the distance between the inner pulleys, and adjusting the inner pulley spacing to be compatible with buried heat exchange tubes with different diameters, eliminating the need for replacement of parts.

[0017] In spring and autumn, the buffer water tank module uses the hot water generated by the solar panels to connect the outlet pipe, return pipe and buried heat exchange pipe to achieve heat compensation for the underground, compensate for the heat storage in the soil, and avoid the soil temperature decreasing year by year, which affects the heating efficiency in winter.

[0037] In the embodiment of the present disclosure, the lower rotating shaft of the middle connecting pipe 103 is rotatably connected to another outer support rod 102, and the tail end of the outer support rod 102 at the lower part of the middle connecting pipe 103 is rotatably connected to the lower connecting fixing frame 104 through the rotating shaft. When the buried pipe rack 1 and the lower threaded rod 105 move closer, the middle connecting pipe 103 moves away from the buried pipe rack 1. After the buried heat exchange pipes 107 expand outward, the distance between the buried heat exchange pipes 107 is further expanded. Compared with the initial compact state, the spacing between the buried heat exchange pipes 107 after expansion can be increased by 2 times, further expanding the influence range of heat exchange of the buried heat exchange pipes 107.

[0038] In the embodiment of the present disclosure, the buried heat exchange pipe 107 is a U-structure, and the two ends of the buried heat exchange pipe 107 respectively pass through the middle connecting pipe 103 on both sides of the buried pipe rack 1. The lower conical base 106 is a conical structure that is wide at the top and narrow at the bottom. The buried heat exchange pipe 107 and the middle connecting pipe 103 are both above the lower conical base 106. The lower conical base 106 enters the ground first, and the lower conical base 106 can block and collide with various stones in the ground and on the hole wall.

[0039] In the embodiment of the present disclosure, the upper and lower parts of the upper auxiliary fixing frame 2 are both rotatably provided with inner pulleys 203. The inner pulley 203 of the upper auxiliary fixing frame 2 and the inner pulley 203 of the side movable slide 202 are arranged opposite to each other. The buried heat exchange pipe 107 is located between the inner pulleys 203 of the upper auxiliary fixing frame 2 and the side movable slide 202. The external threaded rod 204 is threadedly connected to the side movable slide 202. The side movable slide 202 moves with the external threaded rod 204, and the distance between the side movable slide 202 and the inner pulley 203 of the upper auxiliary fixing frame 2 is adjusted. The distance between the side movable slide 202 and the inner pulley 203 of the upper auxiliary fixing frame 2 is adjusted to be compatible with buried heat exchange pipes 107 of different diameters, thereby improving the versatility and applicability of the device.

[0040] Invention 2, based on invention 1, the underground heat exchange pipe 107 and the buffer water tank module 4 and the water outlet port 303 and the return water port 304 are connected and switched in pairs through a three-way valve. The two three-way valves switch the circulation of the underground heat exchange pipe 107 and the buffer water tank module 4 or the circulation state of the water outlet port 303, the return water port 304 and the underground heat exchange pipe 107. The four control valve bodies 305 are replaced by two three-way valves to reduce the difficulty of operation.

[0041] The working principle of the present invention is as follows: first, a hole is drilled in the area where geothermal pre-buried is required, and then the buried pipe rack 1 is installed deep underground. The lower conical base 106 first enters the underground. The lower conical base 106 can block and collide with various stones in the underground and the hole wall, avoiding direct contact between the buried heat exchange pipe 107 and various stones on the hole wall. At the same time, the minimum passing diameter of the hole drilled by the lower conical base 106 is ensured, ensuring that the buried heat exchange pipe 107 can smoothly penetrate into the ground, and the middle connecting pipe 103 and the buried heat exchange pipe 107 are tightly fitted on the buried pipe rack 1. On the outside, the buried heat exchange tube 107 is located at a position smaller than the diameter of the lower conical base 106. The compact structural design effectively reduces the diameter of the entire device, reducing the probability of friction and wear between the buried heat exchange tube 107 and external media such as soil and rock during installation, and reducing the risk of leakage due to wear in the buried heat exchange tube 107 during later use. This improves the safety and reliability of the buried heat exchange tube 107, and reduces the probability of leakage due to wear in the buried heat exchange tube 107 by 15%, thereby extending the service life of the equipment and reducing subsequent maintenance costs.

[0042] After the underground pipe rack 1 moves to the specified depth, the underground pipe rack 1 moves axially along the thread of the lower threaded rod 105, and the underground pipe rack 1 moves close to the lower threaded rod 105. The distance between the upper connecting rotating frame 101 and the lower connecting fixing frame 104 is synchronously closed. The outer support rod 102 connected to the upper connecting rotating frame 101 and the lower connecting fixing frame 104 is tilted toward the horizontal direction. The outer support rod 102 supports the middle connecting pipe 103 and the underground heat exchange pipe 107 to move outward, and the middle connecting pipe 103 and the underground heat exchange pipe 107 move away from the ground. The buried pipe rack 1 is expanded, and the buried heat exchange pipes 107 are expanded outward, further increasing the distance between the buried heat exchange pipes 107. Compared with the initial compact state, the spacing between the buried heat exchange pipes 107 after expansion can be increased by 2 times, further expanding the influence range of the heat exchange of the buried heat exchange pipes 107. The expansion of the heat exchange range means that the heat exchange area between the buried pipes and the surrounding soil is increased, and the heat exchange efficiency is improved, which greatly improves the overall performance of the ground source heat pump system and provides more efficient heating and cooling services for the building.

[0043] When the middle connecting pipe 103 supports the underground heat exchange pipe 107 to expand outward, the middle part of the underground heat exchange pipe 107 bends outward to extend the length deep into the ground, further increasing the length of the underground heat exchange part of the underground heat exchange pipe 107. The upper auxiliary fixing frame 2 is tilted and rotated synchronously, and the underground heat exchange pipe 107 moves outward along the inner pulley 203 and bends. The inner pulley 203 rotates synchronously with the movement of the underground heat exchange pipe 107, reducing the friction resistance of the underground heat exchange pipe 107 during the movement. The inner pulley 203 controls the underground heat exchange pipe 107 to move downward. The bending amplitude of the buried heat exchange pipe 107 avoids the situation where the buried heat exchange pipe 107 is bent too much and causes the water flow to be blocked, thereby ensuring the normal circulation of the fluid in the buried heat exchange pipe 107 and maintaining the efficient operation of the ground source heat pump system. According to the buried heat exchange pipe 107 with different pipe diameters, the thread of the external threaded rod 204 guides the axial movement of the side moving slide 202, and the side moving slide 202 moves with the external threaded rod 204. The distance between the side moving slide 202 and the inner pulley 203 of the upper auxiliary fixing frame 2 is adjusted, so as to flexibly The distance between the side movable slide 202 and the inner pulley 203 of the upper auxiliary fixed frame 2 can be adjusted to achieve compatibility of the inner pulley 203 spacing with underground heat exchange pipes 107 of different diameters, eliminating the need for replacement of parts, greatly improving the versatility and applicability of the device, and reducing equipment procurement and maintenance costs; after the underground pipe rack 1 is installed in place, the underground heat exchange pipe 107 is connected to the outlet pipe 306 and the return pipe 307, and the circulating pump 308 drives the water in the underground pipe rack 1 back to the lower heat exchanger 30 through the underground. 1. The compressor of the heat pump module 3 drives the medium to achieve heat exchange with water in the lower heat exchanger 301. The lower heat exchanger 301 is a tubular heat exchanger. The medium flows through the compressor of the heat pump module 3 to another lower heat exchanger 301. The medium exchanges heat with water at one end of the room in the other lower heat exchanger 301. The other lower heat exchanger 301 is connected to the pipes of the indoor radiator and the indoor fan. The other lower heat exchanger 301 realizes heating or cooling of the indoor terminal, thereby achieving heating or cooling of the room.

[0044] In the spring and autumn seasons when there is no need to start cooling, the outlet port 303, the return water port 304 and the control valve body 305 are closed, and the control valve body 305 of the buffer water tank module 4 is opened to realize the connection between the buffer water tank module 4 and the outlet pipe 306 and the return water pipe 307. The outlet port 303, the return water port 304 and the outlet pipe 306 and the return water pipe 307 are disconnected, and the buffer water tank module 4 uses the hot water continuously generated by the solar panel 401 to connect the outlet pipe 306, the return water pipe 307 and The buried heat exchange pipe 107 compensates for the underground heat and the heat storage of the soil, thereby preventing the soil temperature from decreasing year by year and affecting the heating efficiency in winter. This ensures that the ground source heat pump system can operate stably and efficiently in winter, providing users with a continuous and comfortable heating experience. The buffer water tank module 4 is isolated from the water outlet port 303 and the return water port 304 through the control valve body 305, thereby preventing the high temperature of the buffer water tank module 4 in summer from reducing the heat exchange efficiency of the heat pump module 3.
