Thermal Performance of Ground Heat Exchanger Based on Infinite-Length Linear Heat-Source Model
Based on the principle of superposition, the Infinite-length Linear Heat-source Model (ILM) is applied to the analysis of the long-term performance of Ground Heat Exchanger for Ground Source Heat Pump.The existing heat transfer models, including the Infinite-length Linear Heat-source Model (ILM), the Finite-length Linear Heat-source Model (FLM) and the Infinite-length Cylindrical Heat-source Model (ICM), are compared.It is found that for deep buried pipe, the results of the ILM are exactly the same with that of the FLM, while the results of ICM show large deviation.Comparing with FLM, IFM is of much higher calculation speed which may save lots of computer burden when applying to actual projects.
