Abstract

本報では研究対象とした病院のGSHPシステムについて設計趣旨や研究結果を示すのみではなく、この技術が広く認知され、普及していくことを目標に、設計・施工のプロセスを実際の経験における知見に関して可能な限り掲載することを目指した。施工面ではPHC杭を利用した地中熱ヒートポンプシステムの設計・施工プロセスの解説と、熱応答試験の結果の提示、そしてシステムの最大の特徴である昼夜間採放熱による熱効率向上に関して、設計段階における数値解析を用いた検証結果を示した。

This paper deals with a summary of the GSHP system and the project process, and the anticipated effect of GSHP system. Heat exchange pipes are installed in the PHC foundation. The GSHP system is expected to improve the COP by introducing short term thermal energy storage operation. In this paper, it is shown a condition in the soil as a geologic column, the operating concept, conception drawing, the result of the thermal response test. It is also noted the result of simulation about short term thermal energy storage system of the GSHP system. As the result, annual power consumption of the GSHP and summer season power consumption of the air source Heat Pumps for hot water supply in this model (case2) is estimated 8% lower than usual model (case1).
