小量的不凝性气体可以存在于冷凝器里——特别是那些蒸发器低于大气压运行的冷凝器。有不凝性气体存在的时候,冷凝压力就升高,这是因为传热热阻增大了。因此,压缩机的功率相应与不凝性气体的存在有关。本文的目的是确定不凝性气体对传热的作用,并且建立起已知的不凝性气体量与有 Small amounts of non-condensable gases can be found in condensers - especially those with evaporators operating below subatmospheric pressure. Condensation pressure increases with the presence of non-condensable gases due to increased heat transfer resistance. Therefore, the compressor power corresponding to the presence of non-condensable gases. The purpose of this paper is to determine the effect of non-condensable gases on heat transfer and to establish the relationship between the amount of known non-condensable gases and
