Résumé

Ground source heat pump (GSHP) systems have been gaining attention in recent years as a one of renewable energy utilization system, but its widespread use in Japan has been delayed due to high installation costs. The introduction of horizontal ground heat exchangers (GHEs) has a possibility to reduce the initial cost, therefore, appropriate system design is required to install the horizontal GHEs. The authors developed a simulation tool for GSHP systems using horizontal GHEs. The developed simulation tool can calculate the ground temperature surrounding the GHE, which is affected by not only the heat extraction/injection via GHEs but also the temperature change at ground surface. In addition, this tool calculates the ground temperature surrounding the GHE by superposing the temperature response, and the temperature response of the spiral coil type GHE is calculated by an applying artificial neural network (ANN). In this paper, outlines of calculation method are firstly introduced. Next, the required length of GHE was estimated as a case study using the developed simulation tool.
