Review of Research on Factors Affecting Heat Transfer Characteristics of Horizontally Buried Pipe Heat Exchangers
摘要
Abstract
A review was conducted on the research prog-ress regarding factors influencing the heat transfer characteristics of horizontal ground heat exchangers(HGHEs),summarizing current research gaps and pro-viding suggestions for future research directions.At present,the research on factors affecting the heat trans-fer characteristics of HGHEs primarily focuses on the operational parameters and design parameters of ground heat exchangers,as well as material-related pa-rameters such as soil physical properties,circulating medium,and pipe materials.However,some issues persist.For instance,the simulation and analytical models are often established with numerous simplifi-cations compared to actual buried pipe heat exchang-ers,neglecting the effects of actual dynamic environ-ments and changes in soil thermal conductivity,which can lead to certain deviations from reality.To address issues such as low soil temperature recovery rate and decline in long-term heat exchange efficiency,hybrid ground-source heat pump systems combining ground-water or other energy sources can be constructed.A synergistic approach using nanofluids and phase-change backfill materials is proposed to enhance the heat transfer performance of horizontally buried pipe heat exchangers.The payback period is recommended to be evaluated while considering future economic fluc-tuations to improve the thermal economics of the system.Furthermore,the research on parameter combinations is suggested to be strengthened to comprehensively bal-ance the impacts of various factors on both economic ef-ficiency and heat transfer performance,thereby achiev-ing an optimal equilibrium between the two.关键词
