Abstract Ground source heat pumps (GSHPs) are one of the renewable energy technologies with features high efficiency, saving, economic feasibility and environmental protection. In China, GSHPs have been widely used for building heating cooling in recent years, shown great potential future development. This paper summarizes classification, development history, use status shallow GSHPs. Several typical engineering cases GSHP technology also specified analyzed. Finally, promising trends some...
We present a second law-based investigation on the heat transfer performance of paddle-shaft components. Entropy generation rate distribution is obtained through numerical simulation. show that design with hollow paddles (HP) transfers more and causes larger entropy than solid (SP). For HP, domain produces much less fluid material-solid interface. In domain, for SP, pressure drop-induced irreversibility negligible; it important when flow large. near holes, local largest, fluid-paddle...

The methanol-reforming solid oxide fuel cell (SOFC) emits high concentration of CO2 from the anode outlet. To achieve goal clean and low-carbon power generation, a capture unit is integrated with SOFC. In this work, were set at different places in conventional SOFC gas turbine (GT) hybrid system. One was to place water-gas-shift membrane reactor (WGSMR) inlet (SOFC-MRpre) other outlet (SOFC-MRpost). key parameters, including off-gas recycling ratio (RR), steam-to-carbon (S/C), operating...
A single-leaf type paddle heat exchanger with molten salt as the working fluid is a proper option in high temperature heating processes of materials. In this paper, based on computational dynamics (CFD) simulations, we present thermo-fluid characteristics flowing hollow paddles view both first law and second thermodynamics. The results show that transfer rate significantly greater than solid paddles. penalty enhancement additional pressure drop larger total irreversibility (i.e., entropy...
Excessive thermal stress and deformation are important reasons causing disservice of high temperature heat exchangers. This paper presents expansion analysis single-leaf type hollow paddle-shaft components with internal molten salt flow based on three-dimensional numerical simulations. The results show that the paddles enhance transfer decrease maximum simultaneously expense a much higher pressure drop than solid paddles. cumulative von Mises distribution curve shows component is more...
The ground heat exchanger (GHE) is a critical component of ground-coupled pump (GCHP) system, and its transient transfer performance significantly affects the overall system. Cost reduction through selecting promising GHE offers potential for increased applications. This study performed comprehensive systematic techno-economic analysis characteristics coaxial multi-external-chamber (MECC) GHEs compared to conventional double U-tube (2U) GHE. A three-dimensional numerical model was adopted...
