英文要約Title FY2016 Annual report “Renewable energy-heat utilization technology and development project / Development and standardization of efficiency increasing technology of total system for geo-heat utilization / Development of closed systems using ground heat and flowing water heat (FY2014-FY2016)

In order to promote utilizations of heat from the shallow ground-water and agriculture water and so on as unused heat, we shall carry out
1) Development of a heat exchanger for Shallow Ground-Water-Loop (SGWL) and Surface Flowing Water-Loop (SFWL),
2) Development of optimized operation for heat pump systems, and
3) Development of mapping technology of areas suitable for introduction of the heat from the SGWL and the SFWL, in three years of 2014-2016.
Contents and the result that we carried out in 2016 are as follows.

1) Development of heat exchanger for the SGWL and the SFWL
As the heat exchanger suitable for the SGWL and the SFWL, we chose a sheet-formed polyethylene heat exchanger of 5.6m in length, and 0.9m in width. We started the measurement of the heat exchange performance for the SFWL and the SGWL under the several situations, then we have confirmed with that both of system have been installed with more than 20% less than conventional heat exchangers.

2) Development of the optimized operation for heat pump systems
On the development of load control method for the heat pump systems, we reviewed placement of indoor units of a really used office and carried out adequate load of the heat pump systems, however we might be better to work together with this placement. For verification of systems without non-freezing fluid for both of Akishma and Furumido system, we have been controlled very well with examined temperature detection systems to prevent freeze.

3) Development of the mapping technology of areas suitable for introduction of a heat from the SGWL and the SFWL
We choose a model area and evaluate quantity of natural resources of the SGWL and the SFGL and make the potential map which contributes to select an area suitable for introduction of the heat exchangers for the SFWL and the SGWL.
