Embodiment Construction

[0032] In order to make the purpose, content and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0033] This embodiment proposes a grid division method for a finite element model of a pile foundation spiral buried pipe heat exchanger in a fan-shaped soil area. The grid division method specifically includes the following steps:

[0034] S1. Establish the finite element model of the pile foundation spiral buried tube heat exchanger in the fan-shaped soil area

[0035] The 3D modeling of the finite element model of the pile foundation buried tube heat exchanger in the fan-shaped soil area is carried out by using the DesignModeler software of ANSYS. Among them, the depth of soil area is 50m; the depth of pile foundation is 45m, the radius of pile foundation is 0.5m; the depth of spiral pipe is 44m, the radius of coil p...

Abstract

The invention provides a meshing method for a finite element model of a pile foundation spiral buried pipe heat exchanger in a fan-shaped soil area. The meshing method comprises the steps that the finite element model of the pile foundation spiral buried pipe heat exchanger in the fan-shaped soil area is established; the built finite element model of the pile foundation spiral buried pipe heat exchanger in the fan-shaped soil area is segmented into four parts including lining concrete, soil, a pile foundation inner cylinder and a pile foundation outer circular ring column; and mesh generationis carried out on each segmented part. According to the method, the sequence of grid region division and the minimum size of grid generation are reasonably set, successful grid generation can be guaranteed, the number of generated grids is effectively reduced, the grid generation time is prolonged, and a foundation is laid for subsequent numerical calculation.

Description

technical field [0001] The invention belongs to the technical field of finite element modeling of a ground source heat pump system, and in particular relates to a grid division method for a finite element model of a pile foundation spiral buried pipe heat exchanger in a fan-shaped soil area. Background technique [0002] Ground source heat pump technology is an effective energy-saving technology that uses the shallow soil on the earth's surface as a low-temperature heat source to transfer the heat of the building to the low-temperature soil to achieve the air-conditioning effect of the building. The ground source heat pump system consists of a heat pump unit, a geothermal energy exchange system, and a building system. Among them, the buried pipe heat exchanger is a key component of the geothermal energy exchange system. It places the pipe in the shallow soil on the surface and realizes the exchange and transfer of heat between the circulating water and the soil through water...
