Description

Technical Field

[0001] This utility model relates to the field of ground source heat pump heating devices, and in particular to a high-efficiency ground source heat pump heating device that utilizes waste heat recovery. Background Technology

[0002] Ground source heat pump heating systems are highly efficient heating systems that utilize the working principle of heat pumps. They extract shallow geothermal resources from the earth as a heat source and coolant, transferring and enhancing heat to provide heating services to buildings. Their working principle is based on thermal cycles and the constant temperature characteristics of underground soil or water sources. The system mainly consists of three parts: a buried pipe heat exchange system, a heat pump unit, and indoor terminals. During winter heating, the heat pump unit extracts heat from the soil or groundwater through buried pipes, which is then heated by a compressor and released into the rooms to heat the building. This process achieves the conversion of low-grade heat energy into high-grade heat energy.

[0003] In practical applications, ground source heat pump heating systems face heat dissipation issues during heat transfer. Ground source heat pump systems typically exchange heat with geothermal energy through underground pipes. However, due to factors such as pipe material, soil thermal resistance, pipe length, and ambient temperature, some heat inevitably dissipates into the environment during transmission. This heat dissipation reduces the overall thermal efficiency of the system, thereby increasing energy consumption and operating costs.

[0004] During the heating process, ground source heat pumps generate a certain amount of waste heat, which is typically released into the environment. However, due to technological limitations and economic factors, it is currently difficult to effectively recover and utilize this waste heat. This not only leads to energy waste but may also have negative environmental impacts. To improve the utilization rate of waste heat, some researchers are exploring its application in other fields, such as greenhouse heating and wood processing, but these applications are still in their initial stages and have not yet been widely adopted.
