THE OUTLINE OF THE HEAT SOURCE SYSTEM THAT IS COMBINED WITH THE GROUND SOURCE HEAT PUMP SYSTEM AND THE AQUIFER THERMAL ENERGY STORAGE IN THE SAKATA CITY HALL

Abstract

The subject of this paper is the heat source system with the Ground Source Heat Pump(GSHP) system and the Aquifer Thermal Energy Storage(ATES) system. The site of this city hall building is near from the Mogami River, so the ratio of the soil is almost sand and the level of the underground water is high. Therefore the GSHP and ATES system is expected to make high performance. The heat exchanger of the GSHP system is installed in cast in place concrete foundation. The ATES system is converted from the snow melting equipment using the well water in the summer.
