[0002] A ground source heat pump unit is a device that uses the constant temperature of underground soil or water bodies for heating and cooling. Through heat pump technology, it transfers the heat underground into the building or transfers the heat in the building underground, thus achieving efficient energy utilization.

[0003] The pipes of the existing ground source heat pump units are generally in the outdoor environment. Since the pipes are mainly used for water transportation, the water inside the pipes is likely to freeze in a low-temperature environment.

[0004] In order to overcome the above defects, a Chinese patent of the prior art (publication number: CN206191980U) discloses an energy storage type ground source heat pump unit. Its hot water outlet pipe is nested inside the tap water inlet pipe. The water temperature in the tap water pipe is slightly higher than the air temperature, effectively increasing the heat preservation time of the hot water; at the same time, the tap water pipe contacts the hot water, effectively reducing the frosting phenomenon of the cold water pipe.

[0005] The above prior art optimizes the pipe structure and heats the pipes with hot water, thereby reducing the frosting of the cold water pipes. In the actual use process, the ground source heat pump unit mainly conducts heat exchange between the pipes buried underground and the soil to achieve the heating or cooling of the room. The contact area between the pipes and the soil is limited, resulting in a low heat exchange efficiency. Content of the Utility Model

[0009] Preferably, the heat exchange row is arranged as a hollow structure, and partitions are fixedly connected inside the heat exchange row at equidistant intervals, and the partitions divide the interior of the heat exchange row into heat exchange chambers distributed at equidistant intervals.

[0010] Preferably, both the top and bottom of the heat exchange row are fixedly connected with communicating pipes distributed at equidistant intervals, and the communicating pipes are arranged in a U-shaped structure, and both ends of the communicating pipes are respectively communicated with the interiors of two heat exchange chambers.

[0011] Preferably, the communicating pipes at the top of the heat exchange row and the communicating pipes at the bottom thereof are staggered, and both ends at the top of the heat exchange row are fixedly connected with first diversion pipes, and the lower ends of the first diversion pipes communicate with the interior of the heat exchange chamber.

[0012] Preferably, a pipe structure is arranged at the top of the heat exchange row, and the pipe structure includes a diversion pipe fixedly connected to the top of the first diversion pipe, and a second diversion pipe vertically distributed is fixedly connected to the top of the diversion pipe.

Embodiment Two:

[0036] On the basis of Embodiment One, its specific working principle is as follows:

[0037] This energy storage type ground source heat pump unit is provided with a heat exchange structure. During the use of the device, at this time, the heat exchange row 4 is located in the soil. At this time, the temperature in the soil will enter its interior after passing through the heat exchange row 4, so that the soil heats or absorbs the water temperature inside the heat exchange chamber 7. At the same time, the heat pump unit 1 drives the water inside the heat exchange row 4 to circulate, so that the water circulates indoors through the circulation pipe 3, thereby adjusting the temperature indoors;

[0038] During the heat exchange of the water inside the heat exchange chamber 7, a plurality of convex blocks 5 arranged on the outer side of the heat exchange row 4 make the outer side of the heat exchange row 4 form a wavy structure, so that the contact area between the outer side of the heat exchange row 4 and the soil is increased, thereby improving the heat exchange efficiency of the heat exchange row 4.

At the same time, it protects the diversion pipes 10 and the second diversion pipe 11 to prevent the diversion pipes 10 and the second diversion pipe 11 from being damaged. After the water flows into the interior of the first diversion pipe 9, it enters the heat exchange chamber 7 through the bottom of the first diversion pipe 9. A water path is formed between the heat exchange chamber 7 and the connecting pipe 8, so that the water flows in an S shape inside the heat exchange row 4, increasing the residence time of the water inside the heat exchange row 4 and improving the heat exchange efficiency. The water passing through the interior of the heat exchange row 4 will be transported to the water inlet pipe of the connecting pipe 2 through the first diversion pipe 9 and the third diversion pipe 13. The heat pump unit 1 transports the water inside the water inlet pipe of the connecting pipe 2 to the water outlet pipe of the circulation pipe 3. The water inside the water outlet pipe of the circulation pipe 3 will circulate in the indoor pipes to regulate the indoor temperature.
