Finds documents with exactly this word group, in exactly this word order and spelling (e.g. "employer branding").
Finds documents with both search terms (e.g. sales AND bonus).
Finds documents with one or the other search term (e.g. porsche OR volkswagen).
Finds documents with all search terms. Blank space is understood as AND (e.g. man robot production).
Finds documents with no appearance of the word behind NOT (e.g. ford NOT "harrison ford").
Finds documents where the search term is mentioned at least "n" times."n" may be any number (e.g. COUNT(gear)>8).
Finds documents with both search terms in any word order, permitting "n" words as a maximum distance between them. Best choose between 15 and 30 (e.g. NEAR(recruit, professionals, 20)).
Finds documents with the search term in word versions or composites. The asterisk * marks whether you wish them BEFORE, BEHIND, or BEFORE and BEHIND the search term (e.g. lightweight*, *lightweight, *lightweight*).
Finds documents with the search term in different spellings. "?" allows only one character (e.g. organi?ation).
Special characters are understood as AND (e.g. Miller Bros. & Sons).

Abstract

This chapter explores the enhanced thermal efficiency of borehole heat exchangers (BHEs) using microencapsulated phase change backfill materials (MPCM). The study addresses the critical issue of soil thermal imbalance in severely cold regions, which can lead to declining system performance. Through a three-dimensional numerical model and experimental validation, the research demonstrates that MPCM backfill materials significantly improve heat transfer performance and mitigate soil thermal imbalance. Key findings include a 6-fold increase in average heat transfer rate and a 15.8% improvement in the coefficient of performance (COP) of ground source heat pump (GSHP) systems compared to conventional grout. The study also highlights the ability of MPCM to reduce the thermal influence radius, effectively concentrating heat around the borehole and inhibiting outward heat diffusion. This research provides valuable insights into the potential of MPCM as a sustainable solution for enhancing the efficiency and longevity of geothermal energy systems.
