Abstract: Economic performance of initial investment, operational cost and supplying cost of domestic hot water for different scenarios of ground source heat pump system（GSHPS）, which is designed for a hotel located in the hot summer and warm winter area, have been analyzed using the dynamic annual cost method. The results show that the comprehensive benefit of GSHPS with waste heat recovery is distinct compared with conventional GSHPS. When the ratio of waste heat recovery is 50%, the dynamic annual cost of GSHPS is minimum and achieves the optimizing energy-saving effect.

Key words: ground source heat pump; heat recovery; annual cost; whole life cycle; economic analysis
