摘要：
This paper presents the thermal performance and economic analysis of a compound energy-supply System which composed of a ground source heat pump system (GSHPS) and a thermal energy storage system (TES). This system was simulated by TRNSYS and an engineering project was built for experiment, it's found that the compound system could keep the soil in a better heat balance that is more suitable for discontinuous heating and cooling constructions. From the experiment process, it's found the compound system has a higher COP than common GSHPS by 0.37 in winter and 0.04 in summer. For the price policy of off-peak electricity, the compound system could save 35.2% of the running cost in winter and 18.3% in summer than common GSHPS. In some case, the compound system could also has a lower initial investment. (C) 2016 Elsevier B.V. All rights reserved.
