Abstract: To address the problems of insufficient adaptability and limited operational efficiency of rural decentralized clean energy heating systems, this paper constructs a photovoltaic-heat pump-biomass coupled heating system and develops four core operation and management technologies: load characteristic parameter modeling, dynamic energy regulation, fin anti-frost treatment, and equipment status diagnosis. Practical verification is carried out in typical rural scenarios. This technical system adapts to rural climate conditions, household layout, and operation and maintenance characteristics, effectively improving the operational stability and energy utilization efficiency of the heating system. It provides technical support for the standardized operation of rural decentralized clean energy heating and contributes to the low-carbon transformation of rural energy.
