摘要
针对现有评价冰箱性能指标分析,指出各自的局限性,提出一个能综合评判冰箱特性的新指标——单位折合容积电耗。分析表明,该指标有明确的物理意义,有严格的热力学基础,因此是科学的,文中给出了计算例子,结论指出,新指标可作为评价冰箱性能的准则数。
It' s desirable to have a function parameter that can fairly indicate the relative operating economy of domestic refrigerators of various sizes, types and brands. Analysis indicates that the function parameters currently used have some limitations. A new function parameter called ECPRV is presented which can measure the efficiency of refrigerators. The mechanism for calculating it and examples given show that it can indeed account for the variables that affect energy consumption.
