Energy efficiency analysis and system configuration ofair-source heat pump heating systems

This paper proposes a method of evaluating the heating energy efficiency of the air-source heat pump with the whole heating season as the time span, and obtains a relatively objective and accurate comprehensive energy efficiency ratio of the air-source heat pump system in the heating season. The study results show that the use of this evaluation method is helpful for economic analysis, reasonable configuration and optimization and improvement of control strategy of the air-source heat pump heating system with multi-energy complementation.
