Reasonable supplied water temperature of air-to-water heat pump connected to the floor heating system can save energy and improve comfort. Based on the variation of hourly ambient temperature and ambient temperature, the fuzzy control table is established to adjust the supplied water temperature of the air-to-water heat pump. Considering the energy consumption and unsatisfied time in the whole season, the fuzzy control table is optimized by Hooke-Jeeves algorithm by a 100 m 2 building in Beijing. Comparing the conventional 45 °C supplied water temperature, the simulation results show that the system energy consumption saved by 11.3% and unsatisfied time saved by 9.0% in the whole heating season.
