Summary

REPORTS INVESTIGATIONS INTO THE BEHAVIOUR OF HORIZONTAL SOIL HEAT EXCHANGERS FOR HEAT PUMP SYSTEMS IN ORDER TO TEST A NEW CALCULATION MODEL. EXPERIMENTS WERE CARRIED OUT ON A 10 M LONG SHAFT OF TWO PARALLEL PIPES, WITHOUT A HEAT PUMP. THE MEASUREMENTS LASTED FOR A FULL HEATING SEASON AND THE SUCCEEDING SUMMER PERIOD. AGREEMENT WAS FOUND BETWEEN MEASURED SOIL TEMPERATURES AND CALCULATED HEAT FLOWS PROVIDED THAT FREEZING OF SOIL WAS TAKEN INTO ACCOUNT. FINDS THAT, PER METRE RUN OF PIPE, HEAT WITHDRAWN FROM SOIL BY A VERTICAL SHAFT IS TWICE THAT BY A HORIZONTAL SHAFT. GOES ALSO INTO CURRENT PROJECTS ON VERTICAL SOIL HEAT EXCHANGERS. (INT. BUILD.
