- Abstract
This paper describes the annual energy consumption and economic assessment of air-source heat pump(ASHP) and ground-source heat pump(GSHP),based on hourly building load of typical house in Fuzhou.Analysis results show that the energy consumption of GSHP is 15% less than that of ASHP through all year,where there is 13% less in summer and 20% less in winter.Although the seasonal energy efficiency ratio of GSHP in Fuzhou is higher than that of ASHP,it has no obvious effect on the energy efficiency as it is in the hot summer and cold winter zone.In comparison with ASHP,the GSHP is not cost-effective.
