Study on the Heat Source System Utilizing Combined Underground Heat (Part1)The Outline of the Building Plan and the Heat Source System

Abstract

The city hall of Sakata was designed as environmentally friendly building. Ground Source Heat Pump (GSHP) system and Aquifer Thermal Energy Storage (ATES) system are the significant features of the building. The heat exchanger of GSHP system has been installed in the Cast in-place Concrete Piles. The ATES system is operated as road heating equipment in the winter, and as cooling device of heat source system for air conditioning in the summer. So the heat source system, with is combined operations yields the high performance. This paper describes the outline of the building plan, heat source system and the construction process.
