B-68 Assessment of a Ground Source Heat Pump System in Soen Campus of Sapporo City University : Part-2 Assessment of operation during heating period and comparison to calculation result by using design tool

Abstract

This paper constitutes Part2 in the series of assessment of a ground source heat pump (GSHP) system in Soen campus of Sapporo City University. In this paper, the authors introduce performance and refinement of the GSHP system operation during heating period. In addition, it is shown that the measured temperatures can be reproduced by the calculation with the design tool. Finally, total assessment of the GSHP system is conducted. Then, it is expected that the GSHP can operate with high efficiency long term. From comparison to gas boiler system, the GSHP system can reduce CO_2 emissions and running cost of 40 % and 60 %, respectively.
