AI Technical Summary

Technical Problem

Existing solar collectors have large footprints, high costs, and serious heat dissipation issues. Furthermore, ground source heat pump systems consume a lot of energy during heat extraction, and traditional cross-seasonal heat storage systems have low heat storage density and short cycles, making it difficult to meet the needs of large-scale applications.

Method used

Multiple sets of parallel-arranged heat collection tubes are used, combined with angle-adjustable concave concentrating mirrors and serpentine black corrugated pipes to form a high-efficiency heat collection structure. The high thermal inertia and low thermal conductivity of the lithosphere are used for heat storage. Combined with the coordinated operation of electric three-way valves and water pumps, the automatic switching between heat storage in summer and heat release in winter is realized.

Benefits of technology

It improves solar thermal collection efficiency, reduces energy consumption, enhances thermal storage density and cycle, ensures a stable supply of heat in winter, and reduces operating costs.
