运用模糊数学综合评判方法,从设备初投资、年运行费用、年维护费用和设备寿命4个方面,对太阳能压缩式热泵的经济性进行了研究,并结合具体实例进行验证。结果表明:太阳能压缩式热泵的经济性等级属于较高级别,与实际评标结果吻合较好;建立太阳能压缩式热泵的经济性评价模型,并分别给出一阶模糊评判、二阶模糊评判和评判等级标准;由模糊综合评判法得出的定量结果较好地克服了定性评价方法的主观性和随意性,对太阳能热泵系统的优化设计及推广应用具有良好价值。
By using the fuzzy mathematics comprehensive evaluation method, the economical efficiency of the solar heat pump heat pump is studied from four aspects: equipment investment, annual running cost, annual maintenance cost and equipment life span, and verified with the concrete example. The results show that the economical grade of the solar heat pump heat pump belongs to a higher level, which is in good agreement with the actual evaluation result. The economic evaluation model of the solar heat pump heat pump is established and the first-order fuzzy evaluation, second-order fuzzy evaluation and The quantitative results obtained by the fuzzy comprehensive evaluation method can well overcome the subjectivity and arbitrariness of the qualitative evaluation method and have a good value for the optimal design and popularization and application of the solar heat pump system.
