Embodiment Construction

[0018] The pipe network 1 of the thermal fluid circulation system for solar heat collection and heat absorption of roads or solid structures and thermal fluid circulation system for melting snow and ice to release heat adopts two identical variable-pitch coil arrangements symmetrical to the center line of the road to form a symmetrical double flow. Among them, the pitch gradually increases from the center to both sides or the multi-level different pitch distribution is dense inside and sparse outside. The pitch variation can usually be within 1.5 times, or it can be determined according to road and climate conditions.

[0019]During the road heat collection and heat absorption and underground energy storage stage in summer, the regulating valve 10 and the shut-off valve 2 are opened, and the regulating valve 4 and the shut-off valve 8 are closed. The net 1 circulates from the edge of both sides of the road to the center respectively. At this time, after the solar radiation (sol...

Abstract

The invention provides an energy stepped system based on pipe network arrangement, flow and temperature potential control and a distribution controlling method, particular to a heat fluid circulating system based on solar heat collection and absorption and heat release by snow and ice melting which applies an energy stepped dual-flow pipe network arrangement mode and an all-weather real-time adjustment mode to roads and other similar building structure bodies. The system and the control method are applied to a linking system of two processes of solar heat collection of the road surface and snow and ice melting in winter, thereby strengthening the internal heat exchange of the road surface, not only ensuring effective collection of solar energy in summer and realizing higher outlet temperature of the circulating fluid, but also achieving rapid smelting of accumulated snow and ice at the middle section of the traffic road surface in winter, improving the condition of the traffic road surface and realizing the maximum utilization rate of energy of a dual-circulating fluid in the processes of heat collection in summer and the heat release in winter.

Description

technical field [0001] The invention belongs to the technical field of renewable energy and energy storage utilization, and in particular relates to the design of solar heat collection and snow melting and ice melting systems similar to roads and bridges, and the design and application of solar heat collection or snow melting and ice melting systems for building facilities in the building environment. Background technique [0002] As a new snow-melting and ice-melting method, the thermal fluid circulation heating technology of solar heat collection and underground energy storage not only realizes the functions of solar heat collection underground energy storage in summer and snow melting and ice melting in winter, but also has the function of cross-seasonal utilization of solar energy. Advantages to achieve sustainable utilization of renewable energy. At the same time, heat collection on the road surface in summer can effectively reduce the temperature of the road surface, r...
