Optimal dispatching of household air-source heat pump heating system considering thermal comfort

Abstract

Abstract The use of electric energy substitution technology on the demand side provides a low-carbon solution for energy supply, which is more efficient and environmentally friendly. In order to analyze the economic impact of the indoor temperature set-point on the air-source heat pump heating system considering the thermal comfort, this paper proposed an optimal dispatching method that aims at the lowest daily operating cost. Firstly, a model combined an air-source heat pump heating system and a building was established. Secondly, an optimized dispatching model with the lowest daily operating cost as the goal was built. Finally, a typical case was built and study. And based on weather information released by the Meteorological Station, the system was optimally scheduled at the hour level on a typical day in winter by changing the indoor temperature set-point. Numerical studies demonstrate that the use of the optimized scheduling method proposed in this paper can significantly reduce the electric bill of the air-source heat pump heating system. It will provide customers with a guideline to save electric bill.
