Design and Simulation Analysis of Pile Foundation Ground Source Heat Exchanger System

Abstract:

Pile foundation thermal response test method was adopted to measure the heat transfer capacity of the pile foundation U-pipe heat exchanger of large buildings in Shanghai. The heat exchanger system of pile foundation buried pipe was designed. CFD numerical simulation method was adopted to analyze temperature distribution characteristics of a single concrete pile and dense arrangement of concrete piles heat exchanger. Further, the number and spacing of ground heat exchanger with U-type pile foundation was optimized design . Finally, the U-shaped heat exchanger was buried in the pile base system which was designed to require 24 piles and pile spacing at 12m.
