Analysis on Influence of Yearly Heat Imbalance on Heat Transfer Characteristic of Groundcoupled Heat Pump System

Abstract:

A research is made on heat transfer characteristic of ground heat exchanger (GHE) with different heat imbalance rates,and then,the suggestions such as auxiliary cool and heat source,ground heat pipe adjustment are put forward for better and efficient operation of system.Furthermore,it is much better that installing ground heat exchanger in the area with high groundwater flowrate for the alleviation of soil heat imbalance problems.
