【摘要】：制冷设备产业蓬勃发展，各类产品产量逐年增长，制冷设备的性能评价对规范市场秩序、保证透明消费、促进节能减排事业发展具有重要作用。本文以空调用制冷设备为对象，分析提出其季节性能评价需遵循的原则，评价要素的构建方法，以此分析现行制冷设备季节性能评价方法中存在的问题和改进方法，以及构建新型设备的性能评价体系，对于现行产品标准的修订和新产品标准的建立都具有理论意义和工程应用价值。 本文提出了制冷设备性能指标的确定应遵循公平性、科学性、尽可能反映实际运行效果等原则，其试验方法应遵循方法简单、工况要少、一致性好等原则。对季节性能评价中的三大要素进行研究，验证了建筑负荷线性模型的合理性，明确了空调制冷设备运行时间的统计方法，提出了与真实性能对比以区分各种性能模型准确度的研究方法。 对8台多联机进行全工况制冷或制热性能实验，以实测数据为基础构建了多联机的性能模型，并结合公认的典型建筑负荷和运行时间分布模型，获得多联机季节性能的比较基准，进而分析各种季节性能评价方法及其性能指标的准确性，指出采用ISO标准的APF体系更能反映多联机的实际性能，进而结合中国的建筑负荷特性和气象数据，构建新的多联机季节性能评价体系。 针对冷水机组IPLV季节性能指标存在的争议，从季节性能评价机理出发，提出了一种更能真实反映冷水机组季节性能的新指标——季节部分负荷性能系数（SPLV），并证明了SPLV≤IPLV；分析制冷机房中机组群的“台数控制”特点，，根据单台冷水机组的SPLV的构建思想，推导出机组群的季节性能指标SPLV(N)的计算公式，并给出了SPLV(N)的测量工况。 针对新研发的基站用热虹吸/蒸气压缩复合空调机组的性能特点和应用场合，构建其季节性能评价三要素的数学模型，提出了复合空调机组的APF评价方法，并对一台复合空调机组在我国五个典型地区应用时的季节运行性能进行评价，与实测结果比较表明，所提出的评价方法能够良好地反映产品性能。
[Abstract]:The refrigeration equipment industry is booming and the output of all kinds of products is increasing year by year. The performance evaluation of refrigeration equipment plays an important role in standardizing the market order, ensuring transparent consumption and promoting the development of energy saving and emission reduction.Taking refrigeration equipment for air conditioning as the object, this paper analyzes the principles to be followed in the evaluation of seasonal energy and the method of construction of evaluation elements, so as to analyze the existing problems and improvement methods in the current methods of seasonal performance evaluation of refrigeration equipment.The establishment of new equipment performance evaluation system is of theoretical significance and engineering application value for the revision of current product standards and the establishment of new product standards.This paper puts forward that the determination of performance index of refrigeration equipment should follow the principles of fairness, scientificalness and reflect the actual operation effect as far as possible, and its test method should follow the principles of simple method, less working condition and good consistency.This paper studies the three elements of seasonal energy evaluation, verifies the rationality of the linear model of building load, and clarifies the statistical method of the operating time of air conditioning and refrigeration equipment.A research method is proposed to distinguish the accuracy of various performance models by comparing it with real performance.Based on the measured data, a multi-on-line performance model is constructed for 8 multi-unit cooling or heating performance experiments under full working conditions, and combined with the generally accepted model of building load and running time distribution.The comparison datum of multi-on-line seasonal performance is obtained, and the accuracy of various seasonal performance evaluation methods and performance indexes are analyzed. It is pointed out that the APF system with ISO standard can better reflect the actual performance of multi-online system.Furthermore, a new multi-online seasonal energy evaluation system is constructed based on the characteristics of building load and meteorological data in China.In view of the controversy of seasonal performance index of IPLV of chillers, the mechanism of seasonal performance evaluation is considered.In this paper, a new index which can truly reflect the seasonal performance of chillers, the seasonal partial load performance coefficient is presented, and the SPLV 鈮
