Web Ground Club, which is a cloud-based geothermal heat pump design and performance prediction program, and Japan's Nationwide 3D Grid Strata Database
It can also calculate the effect of multi-layered ground and groundwater flow and incidental cooling towers.
About 10 years ago, we developed Ground Club (GC), a design and performance prediction tool for geothermal heat pump systems (GSHP), and distributed about 150 of these. We have also released an advanced version called Ground Club Cloud (GCC) for cloud computing on a trial basis, and developed a 3D geological properties database for the entire Japan and implemented it in GCC.
Content of research
Potential for social implementation
- ・It is possible to design large-scale GSHP facilities, calculate the performance prediction, and use the data anytime, anywhere.
- ・Performance prediction calculation is possible for ground with rich groundwater flow and multiple strata.
- ・It is possible to evaluate the stability of the ground temperature by adding cooling towers and solar collectors.
- ・It is possible to use a 3D grid strata database.
- ・Geothermal heat utilization potential maps can be developed.
Appealing points to industry and local governments
Ground Club Cloud (GCC) can also be used for systems that include cooling towers, solar collectors, and variable flow control, and can evaluate the stability of underground temperatures and energy efficiency spanning many years, taking into account the effects of groundwater flow. A three-dimensional grid stratum database has been developed using a kriging method based on the stratum information obtained from data of hundreds of thousands of deep wells in Japan, and is installed in GCC so that it can be freely used for design purposes.
