초록
The effect of borehole thermal resistance on the borehole length is studied. In performing this work a new concept BLRR(borehole length reduction rate) is developed based on the line source model. The solution of line source model is shown to be valid through the comparison with the data of thermal response test. It is shown that BLRR is a function of soil thermal conductivity() and borehole thermal resistance(). The value of BLRR increases with increasing , which means reducing is more effective when is high. The reduction of borehole length with change of is easily estimated with BLRR. The validity of BLRR is also examined with EED analysis.
