冷冻管道绝热层的最小厚度,应保证其外表面温度等于最热月的日高温平均值相应的空气露点温度,否则会引起绝热层外层的结露现象,会恶化绝热层的绝热性能,致使冷损失增大。但是,此绝热层露点厚度不一定是经济厚度,随着电能价格的提高与对节电的普遍重视,有必要探讨一下冷冻管道绝热层的经济厚度问题。本文阐明在露点厚度的基础上再增加绝热
The minimum thickness of the insulation layer of the freezing pipeline shall ensure that its outer surface temperature is equal to the air dew point temperature corresponding to the highest daily average of the hottest month, otherwise it will cause the condensation of the outer layer of the insulation layer, which will deteriorate the thermal insulation performance of the insulation layer, resulting in Cold loss increases. However, the thickness of the dew point of this insulation layer is not necessarily the economic thickness. With the increase of the price of electric energy and the general emphasis on power saving, it is necessary to discuss the economic thickness of the insulation layer of the freezing pipe. This article clarifies the increase in thermal insulation based on the dew point thickness
