Evaluation of the Performance of the Groundwater Heat Source System and Examination of Operation Improvement at Education / Research Facility

Abstract

Since geothermal heat is not affected by the outside air condition, and the temperature change is small throughout the year, it is gaining attention as renewable energy that can be used stably. Therefore, in this research, we analyze the relation between the primary energy consumption units of each of the two categories and the heat demand required for the heat source system. In addition, energy saving effect of the groundwater heat source system at the research facility was investigated. As a result, it was confirmed that during actual operation the heat source system using groundwater is an effective system for reducing the primary energy consumption. In addition to the past survey, we examined the optimum operation method of the entire heat source system in the target building.
