Research on Heat-Exchange Efficiency of Buried Pipe with Numerical Method

Abstract:

The heat-exchange efficiency between buried pipes of the ground coupled heat pump and the surrounding soil is influenced by many factors. To design the Heat Pump better, a three-dimensional FEM method which contains buried pipes and considers changing water temperature along the pipe is applied to simulate the heat exchange progress between buried pipes and the surrounding soil. In this paper, the influence of the inlet water temperature, the flow, operating modes and the distance between branches on the heat-exchange efficiency are analyzed and the reasonable suggestions is proposed to benefit the design and operation of the Ground coupled heat pump.
