Description

Technical Field

[0001] The utility model relates to the technical field of ground source heat pumps, in particular to a heat supplement device for ground source heat pumps based on solar energy. Background Art

[0002] A geothermal heat pump is a device that transfers low-grade heat energy to high-grade heat energy by inputting a small amount of high-grade energy (such as electricity) from shallow land energy. A geothermal heat pump is a central air-conditioning system that uses rock mass, stratum soil, groundwater or surface water as a low-temperature heat source, and is composed of a water-based geothermal heat pump unit, a geothermal energy exchange system, and a system within a building. The long-term operation of the central air-conditioning of the geothermal heat pump system leads to an imbalance between the cold and hot loads and underground energy (generally in the north, the heat load is greater than the cold load), and the efficiency of the heat pump project is reduced. Therefore, the heat of solar energy is introduced into the ground to maintain the underground heat balance, so that the geothermal heat pump system can operate efficiently and be applied sustainably in the long term. In the existing patent application with application number CN202022240301.5, a ground source heat pump heat supplement device based on solar energy is proposed. Although the installation angle of the collector body can be adjusted by adjusting the angle between the upper leg and the lower leg, so that the collector body can better absorb solar energy and improve the utilization rate of solar energy, but after the solar collector is used outdoors for a long time, a large amount of dust will accumulate on the vacuum tube used to absorb solar heat to heat water. At this time, the thermal efficiency of the vacuum tube will be reduced. In severe cases, its efficiency in absorbing sunlight will be reduced by more than 20%. In order to ensure the thermal efficiency of the vacuum tube, the vacuum tube must be cleaned regularly. Therefore, a ground source heat pump heat supplement device based on solar energy is needed to solve the above problems. Utility Model Content
