Borehole heat exchangers (BHE) are the most common solution for ground coupled heat pumps (GCHP).The thermal interactions with ground and the GCHP performance are strictly related to a number of fac-tors, including the ground properties, the BHE field geometry, the sequence and strength of heat loadsrequired by the building. A typical...

Design and simulation of borehole heat exchangers rely on the solution of the transient conduction equation. The typical approach for predicting the ground temperature variations in the short and long term is to recursively apply basic thermal response factors available as analytical functions or as pre-estimated tabulated values. In this paper...

The correct design of borehole fields requires the correct evaluation of the transient ground thermal response in time, but also the accurate estimation of the borehole (BHE) thermal resistance, expecially the grout contribution. Generally, the borehole thermal resistance is considered as steady-state; however, when considering the borefield...

Among the renewable energy sources, a particular interest is due to 'low-enthalpy geothermal resources' that allow an advantageous use of heat pumps for winter heating. A correct exploitation of these resources relies on the existence of a general criterion for the choice of the best locations where GCHPs can be successfully installed from the...

In recent years research has increasingly focused on two-phase heat transfer and fluidynamics inside mini and microchannels. Experience of macroscale convective heat transfer inside channels has shown that, at a certain mass velocity, higher heat transfer coefficient can be obtained by reducing the hydraulic diameter at the expense of...

The pool boiling heat transfer and critical heat flux CHF of saturated HFE-7100 at atmospheric pressure on a confined smooth copper surface were experimentally studied. The horizontal upward boiling surface was confined by a face-to-face parallel unheated surface. We analysed the effects obtained by changing the diameter of the unheated surface...
