Abstract Vapor Compression Refrigeration Systems (VCRS) are widely used to provide
cooling or freezing for domestic/office buildings, supermarkets, data centres, etc., which …

Due to the installation of energy piles, the surrounding soil will be inevitably disturbed,
leading to a smaller void ratio and larger thermal conductivity. This study proposes a new …

A thermal response test (TRT) was conducted on a full-scale precast high strength concrete
(PHC) pipe pile installed in multi-layered ground, in order to investigate the thermal …

The ground surface condition is crucial in the thermal analysis of borehole heat exchange
(BHE) systems, as it directly influences the thermal regime within the subsurface. However …

Ground heat exchanges (GHEs) are widely applied in the ground source heat pump (GSHP)
system for exploration of shallow geothermal energy. Heat transfer around a single GHE in …

This paper presents a new analytical multilayer cylindrical heat source model for vertical
ground heat exchangers (GHEs) installed in layered ground using the new integral …

This study presents a field test to investigate the thermal injection performance of a full-scale
energy pile for underground solar energy storage (USES). The tested energy comprises a …

Heat transfer between the ground heat exchanger and surrounding stratum under the action
of groundwater seepage is a potential problem in karst areas, few systematic studies on it …

Borehole heat exchangers (BHEs) are widely used with ground source heat pump (GSHP)
system for utilization of shallow geothermal energy. In this paper, heat transfer between a …

One-dimensional heat conduction process in the cylindrical coordinate is investigated, and a
similarity type of general solution is developed using the Kummer functions. The limiting …
