Problems solved by technology

There are two ways of heat storage, sensible heat storage and latent heat storage. Latent heat storage, such as chemical heat storage, phase change heat storage, etc., especially in application systems that have not reached a certain scale, its economic and technical indicators are not ideal
Sensible heat storage, such as water body heat storage, is widely used in small body heat storage application systems, but water body heat storage is less economical in large-scale heat storage systems

Abstract

The invention relates to the field of heat storage and solar photo-thermal clean energy plus heat supply, in particular to a high-efficiency heat-exchange cross-season heat storage way for soil. The high-efficiency heat-exchange cross-season heat storage way comprises a solar double-shaft groove type heat collector, a solar soil heat-exchange cross-season heat storage unit and a heat energy transformation control unit, wherein the solar double-shaft groove type heat collector comprises a base, a height angle drive mechanism, an azimuth angle drive mechanism, a medium hose, a vacuum heat collecting tube, an upright post and a parabolic heat collection mirror field; the parabolic heat collection mirror field is fixed to the upper end of the upright post; the lower end of the upright post isfixed to the base; the vacuum heat collecting tube is fixed to the axis of the parabolic heat collection mirror field; the parabolic heat collection mirror field is respectively connected with the height angle drive mechanism and the azimuth angle drive mechanism; and the heat energy transformation control unit is electrically connected with the height angle drive mechanism and the azimuth angle drive mechanism. The high-efficiency heat-exchange cross-season heat storage way for soil is utilized to realize large-scale cross-season heat storage, increases the thermal utilization rate of solar light and improves the using efficiency of solar energy.

Description

technical field [0001] The invention relates to the fields of heat storage and solar thermal clean energy + heat supply, in particular to a cross-season heat storage method for soil high-efficiency heat exchange. Background technique [0002] Solar energy is a clean energy, green and pollution-free. It is a real zero-cost energy. It is widely used, but it has certain limitations, such as the discontinuity of day and night, sunny, cloudy, rainy and snowy days. As far as heating is concerned, solar radiation in summer There is a mismatch between supply and demand, such as strong intensity and weak irradiance in the heating season. [0003] It is a very feasible way to store the solar thermal energy in the non-heating season for use in the heating season. There are two ways of heat storage: sensible heat storage and latent heat storage. Latent heat storage, such as chemical heat storage, phase change heat storage, etc., especially in application systems that have not reached a...
