The invention discloses a road heat collecting underground energy storage double temperature difference cascad flow control system. The system comprises a solar heat collecting tube buried under a heat collecting road surface, an underground heat exchanger buried deeply under the solar heat collecting tube, a solar heat collecting circuit sequentially communicating with the solar heat collecting tube, an upstream water tank, a circulation pump and a first electromagnetic regulating valve, an underground energy storage circuit sequentially communicating with the underground heat exchanger, a downstream water tank, a return water pump, a second electromagnetic regulating valve and a third electromagnetic regulating valve, wherein the solar heat collecting circuit and the underground energy storage circuit are connected in parallel and are connected in parallel between the first electromagnetic regulating valve and the second electromagnetic regulating valve as well as at the third electromagnetic regulating valve. Through the solar energy and underground energy storage linkage system, synergy and unification of heat extraction and heat storage are achieved, and the maximum efficiencyof heat collecting and storage is reached. The invention further provides a road heat collecting underground energy storage double temperature difference cascad flow control method.
Description
technical field [0001] The invention relates to the technical field of renewable energy and energy storage utilization, and more specifically, the invention relates to a dual temperature difference cascade flow control system and control method for road heat collection and underground energy storage. Background technique [0002] Utilizing the technology of road heat collection and energy storage to melt snow and ice, on the one hand, the heat collection and storage in summer can collect the solar heat of the road to realize the purpose of "summer energy storage and winter utilization"; on the other hand, it can effectively reduce the temperature of the hot summer road surface Thermal erosion of the pavement can improve the service life of the road, especially for roads with heavy traffic loads (airport runways, highway ports, bridges, slopes and curves, etc.). Therefore, the multiple functions and functions of heat storage, energy storage, snow melting and ice melting techn...
