本文针对冷水机组能效测试名义工况在不同标准、规范之间的分歧,重点讨论了GB/T 18430.1关于污垢系数的调整、调整原因及其带来的影响。提出应根据我国气候和水质条件对污垢系数进行重新修订,并且指出标准规范编制和修订过程中应注重对既有标准规范的衔接。 This paper focuses on the differences between different standards and norms in the energy efficiency test of chiller. It mainly discusses the adjustment and adjustment reasons of GB / T 18430.1 about the fouling coefficient and the impact of the adjustment. It is suggested that the fouling coefficient should be revised according to the climate and water quality conditions in our country. It is also pointed out that the convergence of the existing standards should be emphasized in the process of compiling and revising standards.
