空气源热泵与燃气锅炉供热系统容量配比

CAPACITY CONFIGURATION OF AIR SOURCE HEAT PUMP AND GAS BOILER HEATING SYSTEM

空气源热泵与燃气锅炉联合供热系统在方案阶段的热源容量配比是重要一环,其决定了系统的技术经济性以及运行效果,所以方案比选需兼顾考虑多维评价指标。文中提出了空气源热泵与燃气锅炉联合供热系统容量配比方案优选的技术路径,同时给出了单目标优选法以及基于TOPSIS的多目标优选法。将技术路径应用于寒冷地区某实际工程项目,结果表明基于单目标优选法和多目标优选法的空气源热泵最优容量占比分别为50%和30%。技术路径在具有单一经济性限制指标及多维度限制指标的热源方案优选上均表现出良好的分析能力与适用性,可为联合供热系统容量配比提供方法依据。

The heat source capacity ratio of air source heat pump and gas boiler combined heating system is an im⁃portant parameter in the scheme design,which determines the economy and operation effectiveness of the system,so the multi-dimensional evaluation index should be taken into account in the scheme selection.The technical path of the optimal ratio of the system is proposed,and the single objective optimization method and the multi-objective op⁃timization method based on TOPSIS are given.The results show that the optimal capacity ratio of air source heat pump based on single objective optimization method and multi-objective optimization method is 50%and 30%,re⁃spectively.This technical path shows good analytical ability and applicability in selecting heat source schemes with single economic limit index and multi-dimension limit index.
