In order to understand the implementation effectiveness of the"coal to electricity"project in rural areas of cold regions,a field survey was conducted among rural coal to electricity users in Baoding City,Hebei Province.The usage behavior characteristics of air source heat pump hot water units among rural residents and their heating needs were analyzed.The results show that over 60%of rural households in Baoding area use air source heat pump hot water units all day during the heating season,and the majority of users do not regulate the supply water temperature of the air source heat pump hot water units or the heating terminals of the room during use;Under the heating conditions of air source heat pump hot water units,the heating areas of rural residential buildings are generally the living room and bedroom,and the indoor temperature is mainly concentrated in 16-18℃;The satisfaction survey results of rural residents show that the air source heat pump hot water unit can generally meet the basic heating needs of rural residents.The high operating cost of the heating system and the poor thermal comfort of the heating room are the main problems in the practical application of the air source heat pump hot water unit in rural areas of Baoding.
