Terrestrial heat ventilation system coupled to underground building structure and coupling method thereof

Abstract

The invention discloses a terrestrial heat ventilation system coupled to an underground building structure. The terrestrial heat ventilation system comprises an air inlet pipeline, an air conveying pipeline, a central pipeline, an air outlet pipeline and a blowing unit. The air inlet pipeline is arranged outside a building; the air conveying pipeline is buried underground and horizontally laid, one end of the air conveying pipeline is communicated with the air inlet pipeline, and the other end of the air conveying pipeline is communicated with the central pipeline; the central pipeline is arranged in a building pile, spirally surrounds to the bottom of the building pile along a reinforcing mesh of the building pile and then vertically and upwards penetrates through a bearing platform to extend into the building; and the blowing unit is arranged in the building, an air outlet is formed in one connector of the blowing unit, and the other connector of the blowing unit is communicated with the end, located in the building, of the central pipeline through the air outlet pipeline. According to the system, the central pipeline is laid by utilizing an existing underground space in the building pile structure, so that the problem that the engineering cost is too high is well solved, the operation efficiency of the terrestrial heat ventilation system is effectively improved, and a new thought is provided for the application of a terrestrial heat ventilation system technology.

Description

technical field [0001] The invention relates to the technical field of duct ventilation, in particular to a geothermal ventilation system coupled to an underground building structure and a coupling method thereof. Background technique [0002] In ordinary buildings, such as school classrooms, company office buildings, shopping malls and housing, in order to improve the quality of ventilation in airtight houses, ventilation systems are usually installed. Ventilation systems such as heating, cooling systems and fresh air systems in traditional houses consume high energy and costs, while geothermal ventilation systems have the characteristics of low cost, no pollution, economic feasibility and universal application, and have widely won the favor of the world. It fully meets the needs of the country's sustainable development policy of energy conservation, emission reduction and environmental protection. It uses the earth's shallow geothermal resources to perform simple heat tran...
