Summary

THE PAPER PRESENTS THE RESULTS OF STUDIES CONCERNING VERTICAL SOIL HEAT EXCHANGERS. IT TURNED OUT THAT DRASTICALLY REDUCING INVESTMENT COSTS IS NECESSARY FOR THESE TYPES OF HEAT EXCHANGERS TO BECOME COMPETITIVE WITH AMBIENT AIR AS A HEAT SOURCE FOR HEAT PUMPS. REDUCTION OF COSTS CAN BE ACHIEVED BY IMPROVING DRILLING METHODS, DEVELOPING SPECIAL TOOLS, OPTIMIZING THE CONCENTRIC TUBE AND ORGANIZING THE WORK ON SITE EFFICIENTLY. DEDUCING RELEVANT INFORMATION ON THE SOIL HEAT EXCHANGERS ITSELF, HOWEVER, TURNED OUT TO BE ALMOST IMPOSSIBLE WITHOUT THE HELP OF AN ANALYSIS MODEL, BECAUSE OF THE MANY INTERRELATED VARIABLES INVOLVED. FINALLY, A SURVEY IS PRESENTED OF ALL TOPICS FOR RESEARCH, WHICH COULD LEAD TO AN EFFECTIVE APPLICATION OF HEAT EXCHANGERS FOR THE SOIL AS A HEAT SOURCE.
