چکیده
The ground heat exchanger plays a major role in the thermal performance and economic optimization of ground-coupled pump. present study focuses on effect borehole size grout soil properties assessment these exchangers. A double U-tube was studied numerically by COMSOL Multiphysics 5.4 software 3-dimensional discretization model. circuited as parallel flow arrangement situated configuration (PFPD) deep borehole. conductivities were selected range (0.73-2.0) W/m.K (1.24-2.8) respectively. results revealed that conductivity showed more pronounced influence with less extent for grouting one. Increasing filling from (0.73) to (2.0) at fixed (2.4) has augmented transfer rate (10) %. exhibited marked enhancement much when increased (1.24) (2.8) (0.78-2.0) W/m.K. It been verified increasing negligible high utilized ranged examined configurations. steady-state numerical analysis model outcomes work could be implemented preliminary design exchanger.

Ground Source Heat Pumps (GSHP) are economically and environmentally advantageous for the heating and cooling of buildings, provided that the long-term sustainability of the thermal exploitation of the soil is ensured. In particular, the performance of a closed-loop Borehole Heat Exchanger (BHE) strongly depends on the geometrical and physical properties of its components and on the thermo-hydr...

A simulation model for a vertical U-tube steam condenser in which the condensate is stored at the bottom well is developed in this paper. The U-tubes carrying the coolant are partially submerged in the stored condensate and thus the bottom well acts as a heat exchanger. The storage of hydraulic and thermal energies is represented using a coupled pseudo-bond graph model. Advection effects are mo...

Ground-coupled heat pump (GCHP) systems have been gaining increasing popularity for space air conditioning in buildings due to their reduced energy and maintenance costs. The efficiency of GCHP systems is inherently higher than that of the traditional options because it utilizes the ground which maintains a relatively stable temperature all the year round as a heat source/sink. Compared with tr...
