An overview of the problems and solutions of soil thermal imbalance of ground-coupled heat pumps in cold regions

T You, W Wu, W Shi, B Wang, X Li - Applied Energy, 2016 - Elsevier
Ground-coupled heat pumps are widely applied in cold regions, but soil thermal imbalances
in some projects greatly deteriorate the systems' practical performances and heavily inhibit
the systems' reasonable applications. This paper presents a comprehensive overview of the
main problems caused by soil thermal imbalance and the existing solutions targeting on
them. The caused problems mainly present in the following aspects: soil temperature
decrease, heating performance deterioration, heating reliability decline, and even system …
