Abstract

The invention provides a straight-through vacuum pipe ground cold air taking device and belongs to the technical field of solar energy. An underground air pipe is arranged to obtain cold air, a straight-through vacuum pipe conducts solar heat collection and heating to produce a high-speed air flow to be introduced into an underground air pipe outlet section, solar heat collection air outlet flow forms a pressure difference and generates extraction kinetic energy, and underground pipe cold air is taken and used. The straight-through vacuum pipe ground cold air taking device can also operate in winter to extract underground hot air. The whole taking device and the straight-through vacuum pipe both can be used as basic assemblies to be superimposed in the vertical and transverse directions in a modularization mode to obtain full power and increase the power. The underground pipe can also be connected in series or in parallel to increase the capacity. The straight-through vacuum pipe ground cold air taking device can be used for extracting geothermal energy of soil heat, earth surface water heat, underground water heat and the like. Air heat taking is harmless to soil and the groundwater environment. Full nature passive operation is achieved, and no energy and environmental cost exists. Machining and manufacturing are easy, materials can be cheap, operating maintenance is simple and convenient, and the straight-through vacuum pipe ground cold air taking device can be utilized for industrial and civilian development on occasions of heat collecting, refrigeration, air conditioning, ventilation, drying, technique processes and the like.

Description

technical field [0001] The invention relates to a ground-cooled air extractor, which is driven by the buoyancy force generated by the solar heat collection and heating of a straight-through vacuum tube to generate a high-speed air flow, which is used to flow upward in the geothermal buried pipe to generate an extraction effect and obtain geothermal buried Geocooled air in the tube. The cold air extraction device here operates in winter and can also extract the hot air in the geothermal buried pipe. And it can be applied not only to the extraction of soil heat, but also to the extraction of surface water and groundwater heat. The invention belongs to the technical field of solar energy. Background technique [0002] Solar energy and soil heat are all green natural energy sources. Corresponding to the same heat generated by consuming fossil energy or direct electricity consumption, the effective use of solar energy and geothermal energy can eliminate and reduce energy and en...
