PERFORMANCE AND FEASIBILITY STUDY OF HYBRID GROUND SOURCE HEAT PUMP SYSTEM FOR A PUBLIC BUILDING BASED ON A BEIJING CASE

ABSTRACT
With the increasing demand for renewable energy sources, shallow geothermal energy has become a reliable alternative energy source for building heating and cooling. In this paper, we present a methodology for estimating the shallow geothermal potential to meet heating demand for a public building. Firstly, the geothermal reserves and the cooling heating demand of the building are evaluated. Then the simulation model of hybrid ground source heat pump system is established, which aims at solving the problem of soil heat accumulation. Finally, one-year and five-year variation of performance parameters of hybrid ground source heat pump system are calculated. Our results indicate that hybrid ground source heat pump system could effectively solve heat accumulation problem and reduce traditional energy consumption.
