沈阳市农村公共建筑空气源热泵供热系统运行策略研究

Study on the operation strategy of air source heat pump heating system in Shenyang rural public buildings

针对沈阳农村地区公共建筑清洁取暖改造需求,开展农村地区公共建筑现状调研,建立建筑物室内温度预测模型,优化农村公共建筑空气源热泵供热系统的运行策略。研究结果表明,空气源热泵供热系统可以满足严寒地区公共建筑的供热需求,采暖季应结合建筑蓄热特性充分利用谷电时间为农村公共建筑供热,PSO-BP仿真模型预测表明供水温度35℃时亦可满足采暖初、末期的供热需求。

According to the demand for clean heating renovation of public buildings in rural areas of Shenyang,the current situation of public buildings in rural areas was investigated.We establish the indoor temperature prediction model of the building.At the same time,we set up the indoor temperature prediction model of the building.The operation strategy of air source heat pump heating system in rural public buildings is optimized.The research results show that the air source heat pump heating system can meet the heating demand of rural public buildings in cold areas.Combined with the characteristics of building thermal storage,we should make full use of valley time to heat rural public buildings.The prediction of PSO-BP simulation model shows that the supply water temperature of 35℃ can also meet the heating demand at the beginning and end of the heating season.
